COMMANDS
Repository creation
clone
make a copy of an existing repository:
hg clone [OPTION]... SOURCE [DEST]
Create a copy of an existing repository in a new directory.
If no destination directory name is specified, it defaults to the basename of the source.
The location of the source is added to the new repository's .hg/hgrc file, as the default to be used for
future pulls.
Only local paths and ssh:// URLs are supported as destinations. For ssh:// destinations, no working
directory or .hg/hgrc will be created on the remote side.
If the source repository has a bookmark called '@' set, that revision will be checked out in the new
repository by default.
To check out a particular version, use -u/--update, or -U/--noupdate to create a clone with no working
directory.
To pull only a subset of changesets, specify one or more revisions identifiers with -r/--rev or branches
with -b/--branch. The resulting clone will contain only the specified changesets and their ancestors.
These options (or 'clone src#rev dest') imply --pull, even for local source repositories.
In normal clone mode, the remote normalizes repository data into a common exchange format and the
receiving end translates this data into its local storage format. --stream activates a different clone
mode that essentially copies repository files from the remote with minimal data processing. This
significantly reduces the CPU cost of a clone both remotely and locally. However, it often increases the
transferred data size by 30-40%. This can result in substantially faster clones where I/O throughput is
plentiful, especially for larger repositories. A side-effect of --stream clones is that storage settings
and requirements on the remote are applied locally: a modern client may inherit legacy or inefficient
storage used by the remote or a legacy Mercurial client may not be able to clone from a modern Mercurial
remote.
Note Specifying a tag will include the tagged changeset but not the changeset containing the tag.
For efficiency, hardlinks are used for cloning whenever the source and destination are on the same
filesystem (note this applies only to the repository data, not to the working directory). Some
filesystems, such as AFS, implement hardlinking incorrectly, but do not report errors. In these cases,
use the --pull option to avoid hardlinking.
Mercurial will update the working directory to the first applicable revision from this list:
a. null if -U or the source repository has no changesets
b. if -u . and the source repository is local, the first parent of the source repository's working
directory
c. the changeset specified with -u (if a branch name, this means the latest head of that branch)
d. the changeset specified with -r
e. the tipmost head specified with -b
f. the tipmost head specified with the url#branch source syntax
g. the revision marked with the '@' bookmark, if present
h. the tipmost head of the default branch
i. tip
When cloning from servers that support it, Mercurial may fetch pre-generated data from a
server-advertised URL or inline from the same stream. When this is done, hooks operating on incoming
changesets and changegroups may fire more than once, once for each pre-generated bundle and as well as
for any additional remaining data. In addition, if an error occurs, the repository may be rolled back to
a partial clone. This behavior may change in future releases. See hg help -e clonebundles for more.
Examples:
• clone a remote repository to a new directory named hg/:
hg clone https://www.mercurial-scm.org/repo/hg/
• create a lightweight local clone:
hg clone project/ project-feature/
• clone from an absolute path on an ssh server (note double-slash):
hg clone ssh://user@server//home/projects/alpha/
• do a streaming clone while checking out a specified version:
hg clone --stream http://server/repo -u 1.5
• create a repository without changesets after a particular revision:
hg clone -r 04e544 experimental/ good/
• clone (and track) a particular named branch:
hg clone https://www.mercurial-scm.org/repo/hg/#stable
See hg help urls for details on specifying URLs.
Returns 0 on success.
Options:
-U, --noupdate
the clone will include an empty working directory (only a repository)
-u,--updaterev <REV>
revision, tag, or branch to check out
-r,--rev <REV[+]>
do not clone everything, but include this changeset and its ancestors
-b,--branch <BRANCH[+]>
do not clone everything, but include this branch's changesets and their ancestors
--pull use pull protocol to copy metadata
--uncompressed
an alias to --stream (DEPRECATED)
--stream
clone with minimal data processing
-e,--ssh <CMD>
specify ssh command to use
--remotecmd <CMD>
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
[+] marked option can be specified multiple times
init
create a new repository in the given directory:
hg init [-e CMD] [--remotecmd CMD] [DEST]
Initialize a new repository in the given directory. If the given directory does not exist, it will be
created.
If no directory is given, the current directory is used.
It is possible to specify an ssh:// URL as the destination. See hg help urls for more information.
Returns 0 on success.
Options:
-e,--ssh <CMD>
specify ssh command to use
--remotecmd <CMD>
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
Remote repository management
incoming
show new changesets found in source:
hg incoming [-p] [-n] [-M] [-f] [-r REV]... [--bundle FILENAME] [SOURCE]
Show new changesets found in the specified path/URL or the default pull location. These are the
changesets that would have been pulled by hg pull at the time you issued this command.
See pull for valid source format details.
With -B/--bookmarks, the result of bookmark comparison between local and remote repositories is
displayed. With -v/--verbose, status is also displayed for each bookmark like below:
BM1 01234567890a added
BM2 1234567890ab advanced
BM3 234567890abc diverged
BM4 34567890abcd changed
The action taken locally when pulling depends on the status of each bookmark:
added
pull will create it
advanced
pull will update it
diverged
pull will create a divergent bookmark
changed
result depends on remote changesets
From the point of view of pulling behavior, bookmark existing only in the remote repository are treated
as added, even if it is in fact locally deleted.
For remote repository, using --bundle avoids downloading the changesets twice if the incoming is followed
by a pull.
Examples:
• show incoming changes with patches and full description:
hg incoming -vp
• show incoming changes excluding merges, store a bundle:
hg in -vpM --bundle incoming.hg
hg pull incoming.hg
• briefly list changes inside a bundle:
hg in changes.hg -T "{desc|firstline}\n"
Returns 0 if there are incoming changes, 1 otherwise.
Options:
-f, --force
run even if remote repository is unrelated
-n, --newest-first
show newest record first
--bundle <FILE>
file to store the bundles into
-r,--rev <REV[+]>
a remote changeset intended to be added
-B, --bookmarks

-b,--branch <BRANCH[+]>
a specific branch you would like to pull
-p, --patch
show patch
-g, --git
use git extended diff format
-l,--limit <NUM>

-M, --no-merges
do not show merges
--stat output diffstat-style summary of changes
-G, --graph

--style <STYLE>
display using template map file (DEPRECATED)
-T,--template <TEMPLATE>
display with template
-e,--ssh <CMD>
specify ssh command to use
--remotecmd <CMD>
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
-S, --subrepos
recurse into subrepositories
[+] marked option can be specified multiple times
aliases: in
outgoing
show changesets not found in the destination:
hg outgoing [-M] [-p] [-n] [-f] [-r REV]... [DEST]...
Show changesets not found in the specified destination repository or the default push location. These are
the changesets that would be pushed if a push was requested.
See pull for details of valid destination formats.
With -B/--bookmarks, the result of bookmark comparison between local and remote repositories is
displayed. With -v/--verbose, status is also displayed for each bookmark like below:
BM1 01234567890a added
BM2 deleted
BM3 234567890abc advanced
BM4 34567890abcd diverged
BM5 4567890abcde changed
The action taken when pushing depends on the status of each bookmark:
added
push with -B will create it
deleted
push with -B will delete it
advanced
push will update it
diverged
push with -B will update it
changed
push with -B will update it
From the point of view of pushing behavior, bookmarks existing only in the remote repository are treated
as deleted, even if it is in fact added remotely.
Returns 0 if there are outgoing changes, 1 otherwise.
Options:
-f, --force
run even when the destination is unrelated
-r,--rev <REV[+]>
a changeset intended to be included in the destination
-n, --newest-first
show newest record first
-B, --bookmarks
compare bookmarks
-b,--branch <BRANCH[+]>
a specific branch you would like to push
-p, --patch

-S, --subrepos
recurse into subrepositories
[+] marked option can be specified multiple times
aliases: out
paths
show aliases for remote repositories:
hg paths [NAME]
Show definition of symbolic path name NAME. If no name is given, show definition of all available names.
Option -q/--quiet suppresses all output when searching for NAME and shows only the path names when
listing all definitions.
Path names are defined in the [paths] section of your configuration file and in /etc/mercurial/hgrc. If
run inside a repository, .hg/hgrc is used, too.
The path names default and default-push have a special meaning. When performing a push or pull
operation, they are used as fallbacks if no location is specified on the command-line. When default-push
is set, it will be used for push and default will be used for pull; otherwise default is used as the
fallback for both. When cloning a repository, the clone source is written as default in .hg/hgrc.
Note default and default-push apply to all inbound (e.g. hg incoming) and outbound (e.g. hg outgoing,
hg email and hg bundle) operations.
See hg help urls for more information.
Template:
The following keywords are supported. See also hg help templates.
name String. Symbolic name of the path alias.
pushurl
String. URL for push operations.
url String. URL or directory path for the other operations.
Returns 0 on success.
Options:
-T,--template <TEMPLATE>
display with template
pull
pull changes from the specified source:
hg pull [-u] [-f] [-r REV]... [-e CMD] [--remotecmd CMD] [SOURCE]...
Pull changes from a remote repository to a local one.
This finds all changes from the repository at the specified path or URL and adds them to a local
repository (the current one unless -R is specified). By default, this does not update the copy of the
project in the working directory.
When cloning from servers that support it, Mercurial may fetch pre-generated data. When this is done,
hooks operating on incoming changesets and changegroups may fire more than once, once for each
pre-generated bundle and as well as for any additional remaining data. See hg help -e clonebundles for
more.
Use hg incoming if you want to see what would have been added by a pull at the time you issued this
command. If you then decide to add those changes to the repository, you should use hg pull -r X where X
is the last changeset listed by hg incoming.
If SOURCE is omitted, the 'default' path will be used. See hg help urls for more information.
If multiple sources are specified, they will be pulled sequentially as if the command was run multiple
time. If --update is specify and the command will stop at the first failed --update.
Specifying bookmark as . is equivalent to specifying the active bookmark's name.
One can use the --remote-hidden flag to pull changesets hidden on the remote. This flag is "best effort",
and will only work if the server supports the feature and is configured to allow the user to access
hidden changesets. This option is experimental and backwards compatibility is not garanteed.
Returns 0 on success, 1 if an update had unresolved files.
Options:
-u, --update
update to new branch head if new descendants were pulled
-f, --force
run even when remote repository is unrelated
--confirm
confirm pull before applying changes
-r,--rev <REV[+]>
a remote changeset intended to be added
-B,--bookmark <BOOKMARK[+]>
bookmark to pull
-b,--branch <BRANCH[+]>
a specific branch you would like to pull
--remote-hidden
include changesets hidden on the remote (EXPERIMENTAL)
-e,--ssh <CMD>
specify ssh command to use
--remotecmd <CMD>
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
[+] marked option can be specified multiple times
push
push changes to the specified destination:
hg push [-f] [-r REV]... [-e CMD] [--remotecmd CMD] [DEST]...
Push changesets from the local repository to the specified destination.
This operation is symmetrical to pull: it is identical to a pull in the destination repository from the
current one.
By default, push will not allow creation of new heads at the destination, since multiple heads would make
it unclear which head to use. In this situation, it is recommended to pull and merge before pushing.
Use --new-branch if you want to allow push to create a new named branch that is not present at the
destination. This allows you to only create a new branch without forcing other changes.
Note Extra care should be taken with the -f/--force option, which will push all new heads on all
branches, an action which will almost always cause confusion for collaborators.
If -r/--rev is used, the specified revision and all its ancestors will be pushed to the remote
repository.
If -B/--bookmark is used, the specified bookmarked revision, its ancestors, and the bookmark will be
pushed to the remote repository. Specifying . is equivalent to specifying the active bookmark's name. Use
the --all-bookmarks option for pushing all current bookmarks.
Please see hg help urls for important details about ssh:// URLs. If DESTINATION is omitted, a default
path will be used.
When passed multiple destinations, push will process them one after the other, but stop should an error
occur.
The --pushvars option sends strings to the server that become environment variables prepended with
HG_USERVAR_. For example, --pushvars ENABLE_FEATURE=true, provides the server side hooks with
HG_USERVAR_ENABLE_FEATURE=true as part of their environment.
pushvars can provide for user-overridable hooks as well as set debug levels. One example is having a hook
that blocks commits containing conflict markers, but enables the user to override the hook if the file is
using conflict markers for testing purposes or the file format has strings that look like conflict
markers.
By default, servers will ignore --pushvars. To enable it add the following to your configuration file:
[push]
pushvars.server = true
Returns 0 if push was successful, 1 if nothing to push.
Options:
-f, --force
force push
-r,--rev <REV[+]>
a changeset intended to be included in the destination
-B,--bookmark <BOOKMARK[+]>
bookmark to push
--all-bookmarks
push all bookmarks (EXPERIMENTAL)
-b,--branch <BRANCH[+]>
a specific branch you would like to push
--new-branch
allow pushing a new branch
--pushvars <VALUE[+]>
variables that can be sent to server (ADVANCED)
--publish
push the changeset as public (EXPERIMENTAL)
-e,--ssh <CMD>
specify ssh command to use
--remotecmd <CMD>
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
[+] marked option can be specified multiple times
serve
start stand-alone webserver:
hg serve [OPTION]...
Start a local HTTP repository browser and pull server. You can use this for ad-hoc sharing and browsing
of repositories. It is recommended to use a real web server to serve a repository for longer periods of
time.
Please note that the server does not implement access control. This means that, by default, anybody can
read from the server and nobody can write to it by default. Set the web.allow-push option to * to allow
everybody to push to the server. You should use a real web server if you need to authenticate users.
By default, the server logs accesses to stdout and errors to stderr. Use the -A/--accesslog and
-E/--errorlog options to log to files.
To have the server choose a free port number to listen on, specify a port number of 0; in this case, the
server will print the port number it uses.
Returns 0 on success.
Options:
-A,--accesslog <FILE>
name of access log file to write to
-d, --daemon
run server in background
--daemon-postexec <VALUE[+]>
used internally by daemon mode
-E,--errorlog <FILE>
name of error log file to write to
-p,--port <PORT>
port to listen on (default: 8000)
-a,--address <ADDR>
address to listen on (default: all interfaces)
--prefix <PREFIX>
prefix path to serve from (default: server root)
-n,--name <NAME>
name to show in web pages (default: working directory)
--web-conf <FILE>
name of the hgweb config file (see 'hg help hgweb')

-6, --ipv6
use IPv6 instead of IPv4
--certificate <FILE>
SSL certificate file
--print-url
start and print only the URL
-S, --subrepos
recurse into subrepositories
[+] marked option can be specified multiple times
Change creation
commit
commit the specified files or all outstanding changes:
hg commit [OPTION]... [FILE]...
Commit changes to the given files into the repository. Unlike a centralized SCM, this operation is a
local operation. See hg push for a way to actively distribute your changes.
If a list of files is omitted, all changes reported by hg status will be committed.
If you are committing the result of a merge, do not provide any filenames or -I/-X filters.
If no commit message is specified, Mercurial starts your configured editor where you can enter a message.
In case your commit fails, you will find a backup of your message in .hg/last-message.txt.
The --close-branch flag can be used to mark the current branch head closed. When all heads of a branch
are closed, the branch will be considered closed and no longer listed.
The --amend flag can be used to amend the parent of the working directory with a new commit that contains
the changes in the parent in addition to those currently reported by hg status, if there are any. The old
commit is stored in a backup bundle in .hg/strip-backup (see hg help bundle and hg help unbundle on how
to restore it).
Message, user and date are taken from the amended commit unless specified. When a message isn't specified
on the command line, the editor will open with the message of the amended commit.
It is not possible to amend public changesets (see hg help phases) or changesets that have children.
See hg help dates for a list of formats valid for -d/--date.
Returns 0 on success, 1 if nothing changed.
Examples:
• commit all files ending in .py:
hg commit --include "set:**.py"
• commit all non-binary files:
hg commit --exclude "set:binary()"
• amend the current commit and set the date to now:
hg commit --amend --date now
Options:
-A, --addremove
mark new/missing files as added/removed before committing
--close-branch
mark a branch head as closed
--amend
amend the parent of the working directory
-s, --secret
use the secret phase for committing
--draft
use the draft phase for committing
-e, --edit
invoke editor on commit messages
--force-close-branch
forcibly close branch from a non-head changeset (ADVANCED)
-i, --interactive
use interactive mode
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
-m,--message <TEXT>
use text as commit message
-l,--logfile <FILE>
read commit message from file
-d,--date <DATE>
record the specified date as commit date
-u,--user <USER>
record the specified user as committer
-S, --subrepos
recurse into subrepositories
[+] marked option can be specified multiple times
aliases: ci
Change manipulation
abort
abort an unfinished operation (EXPERIMENTAL):
hg abort
Aborts a multistep operation like graft, histedit, rebase, merge, and unshelve if they are in an
unfinished state.
use --dry-run/-n to dry run the command.
Options:
-n, --dry-run
do not perform actions, just print output
backout
reverse effect of earlier changeset:
hg backout [OPTION]... [-r] REV
Prepare a new changeset with the effect of REV undone in the current working directory. If no conflicts
were encountered, it will be committed immediately.
If REV is the parent of the working directory, then this new changeset is committed automatically (unless
--no-commit is specified).
Note hg backout cannot be used to fix either an unwanted or incorrect merge.
Examples:
• Reverse the effect of the parent of the working directory. This backout will be committed immediately:
hg backout -r .
• Reverse the effect of previous bad revision 23:
hg backout -r 23
• Reverse the effect of previous bad revision 23 and leave changes uncommitted:
hg backout -r 23 --no-commit
hg commit -m "Backout revision 23"
By default, the pending changeset will have one parent, maintaining a linear history. With --merge, the
pending changeset will instead have two parents: the old parent of the working directory and a new child
of REV that simply undoes REV.
Before version 1.7, the behavior without --merge was equivalent to specifying --merge followed by hg
update --clean . to cancel the merge and leave the child of REV as a head to be merged separately.
See hg help dates for a list of formats valid for -d/--date.
See hg help revert for a way to restore files to the state of another revision.
Returns 0 on success, 1 if nothing to backout or there are unresolved files.
Options:
--merge
merge with old dirstate parent after backout
--commit
commit if no conflicts were encountered (DEPRECATED)
--no-commit
do not commit
--parent <REV>
parent to choose when backing out merge (DEPRECATED)
-r,--rev <REV>

-e, --edit
invoke editor on commit messages
-t,--tool <TOOL>

-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>

-l,--logfile <FILE>
read commit message from file
-d,--date <DATE>

[+] marked option can be specified multiple times
continue
resumes an interrupted operation (EXPERIMENTAL):
hg continue
Finishes a multistep operation like graft, histedit, rebase, merge, and unshelve if they are in an
interrupted state.
use --dry-run/-n to dry run the command.
Options:
-n, --dry-run
do not perform actions, just print output
graft
copy changes from other branches onto the current branch:
hg graft [OPTION]... [-r REV]... REV...
This command uses Mercurial's merge logic to copy individual changes from other branches without merging
branches in the history graph. This is sometimes known as 'backporting' or 'cherry-picking'. By default,
graft will copy user, date, and description from the source changesets.
Changesets that are ancestors of the current revision, that have already been grafted, or that are merges
will be skipped.
If --log is specified, log messages will have a comment appended of the form:
(grafted from CHANGESETHASH)
If --force is specified, revisions will be grafted even if they are already ancestors of, or have been
grafted to, the destination. This is useful when the revisions have since been backed out.
If a graft merge results in conflicts, the graft process is interrupted so that the current merge can be
manually resolved. Once all conflicts are addressed, the graft process can be continued with the
-c/--continue option.
The -c/--continue option reapplies all the earlier options.
The --base option exposes more of how graft internally uses merge with a custom base revision. --base can
be used to specify another ancestor than the first and only parent.
The command:
hg graft -r 345 --base 234
is thus pretty much the same as:
hg diff --from 234 --to 345 | hg import
but using merge to resolve conflicts and track moved files.
The result of a merge can thus be backported as a single commit by specifying one of the merge parents as
base, and thus effectively grafting the changes from the other side.
It is also possible to collapse multiple changesets and clean up history by specifying another ancestor
as base, much like rebase --collapse --keep.
The commit message can be tweaked after the fact using commit --amend .
For using non-ancestors as the base to backout changes, see the backout command and the hidden --parent
option.
Examples:
• copy a single change to the stable branch and edit its description:
hg update stable
hg graft --edit 9393
• graft a range of changesets with one exception, updating dates:
hg graft -D "2085::2093 and not 2091"
• continue a graft after resolving conflicts:
hg graft -c
• show the source of a grafted changeset:
hg log --debug -r .
• show revisions sorted by date:
hg log -r "sort(all(), date)"
• backport the result of a merge as a single commit:
hg graft -r 123 --base 123^
• land a feature branch as one changeset:
hg up -cr default
hg graft -r featureX --base "ancestor('featureX', 'default')"
See hg help revisions for more about specifying revisions.
Returns 0 on successful completion, 1 if there are unresolved files.
Options:
-r,--rev <REV[+]>

record the current user as committer
-d,--date <DATE>
record the specified date as commit date
-u,--user <USER>
record the specified user as committer
-t,--tool <TOOL>
specify merge tool
-n, --dry-run
do not perform actions, just print output
[+] marked option can be specified multiple times
merge
merge another revision into working directory:
hg merge [-P] [[-r] REV]
The current working directory is updated with all changes made in the requested revision since the last
common predecessor revision.
Files that changed between either parent are marked as changed for the next commit and a commit must be
performed before any further updates to the repository are allowed. The next commit will have two
parents.
--tool can be used to specify the merge tool used for file merges. It overrides the HGMERGE environment
variable and your configuration files. See hg help merge-tools for options.
If no revision is specified, the working directory's parent is a head revision, and the current branch
contains exactly one other head, the other head is merged with by default. Otherwise, an explicit
revision with which to merge must be provided.
See hg help resolve for information on handling file conflicts.
To undo an uncommitted merge, use hg merge --abort which will check out a clean copy of the original
merge parent, losing all changes.
Returns 0 on success, 1 if there are unresolved files.
Options:
-f, --force
force a merge including outstanding changes (DEPRECATED)

bookmarks
create a new bookmark or list existing bookmarks:
hg bookmarks [OPTIONS]... [NAME]...
Bookmarks are labels on changesets to help track lines of development. Bookmarks are unversioned and can
be moved, renamed and deleted. Deleting or moving a bookmark has no effect on the associated changesets.
Creating or updating to a bookmark causes it to be marked as 'active'. The active bookmark is indicated
with a '*'. When a commit is made, the active bookmark will advance to the new commit. A plain hg
update will also advance an active bookmark, if possible. Updating away from a bookmark will cause it to
be deactivated.
Bookmarks can be pushed and pulled between repositories (see hg help push and hg help pull). If a shared
bookmark has diverged, a new 'divergent bookmark' of the form 'name@path' will be created. Using hg merge
will resolve the divergence.
Specifying bookmark as '.' to -m/-d/-l options is equivalent to specifying the active bookmark's name.
A bookmark named '@' has the special property that hg clone will check it out by default if it exists.
Template:
The following keywords are supported in addition to the common template keywords and functions such as
{bookmark}. See also hg help templates.
active Boolean. True if the bookmark is active.
Examples:
• create an active bookmark for a new line of development:
hg book new-feature
• create an inactive bookmark as a place marker:
hg book -i reviewed
• create an inactive bookmark on another changeset:
hg book -r .^ tested
• rename bookmark turkey to dinner:
hg book -m turkey dinner
• move the '@' bookmark from another branch:
hg book -f @
• print only the active bookmark name:
hg book -ql .
Options:
-f, --force
force
-r,--rev <REV>
revision for bookmark action
-d, --delete
delete a given bookmark
-m,--rename <OLD>
rename a given bookmark
-i, --inactive
mark a bookmark inactive
-l, --list
list existing bookmarks
-T,--template <TEMPLATE>
display with template
aliases: bookmark
branch
set or show the current branch name:
hg branch [-fC] [NAME]
Note Branch names are permanent and global. Use hg bookmark to create a light-weight bookmark instead.
See hg help glossary for more information about named branches and bookmarks.
With no argument, show the current branch name. With one argument, set the working directory branch name
(the branch will not exist in the repository until the next commit). Standard practice recommends that
primary development take place on the 'default' branch.
Unless -f/--force is specified, branch will not let you set a branch name that already exists.
Use -C/--clean to reset the working directory branch to that of the parent of the working directory,
negating a previous branch change.
Use the command hg update to switch to an existing branch. Use hg commit --close-branch to mark this
branch head as closed. When all heads of a branch are closed, the branch will be considered closed.
Returns 0 on success.
Options:
-f, --force
set branch name even if it shadows an existing branch
-C, --clean
reset branch name to parent branch name
-r,--rev <VALUE[+]>
change branches of the given revs (EXPERIMENTAL)
[+] marked option can be specified multiple times
branches
list repository named branches:
hg branches [-c]
List the repository's named branches, indicating which ones are inactive. If -c/--closed is specified,
also list branches which have been marked closed (see hg commit --close-branch).
Use the command hg update to switch to an existing branch.
Template:
The following keywords are supported in addition to the common template keywords and functions such as
{branch}. See also hg help templates.
active Boolean. True if the branch is active.
closed Boolean. True if the branch is closed.
current
Boolean. True if it is the current branch.
Returns 0.
Options:
-a, --active
show only branches that have unmerged heads (DEPRECATED)
-c, --closed
show normal and closed branches
-r,--rev <VALUE[+]>
show branch name(s) of the given rev
-T,--template <TEMPLATE>
display with template
[+] marked option can be specified multiple times
phase
set or show the current phase name:
hg phase [-p|-d|-s] [-f] [-r] [REV...]
With no argument, show the phase name of the current revision(s).
With one of -p/--public, -d/--draft or -s/--secret, change the phase value of the specified revisions.
Unless -f/--force is specified, hg phase won't move changesets from a lower phase to a higher phase.
Phases are ordered as follows:
public < draft < secret
Returns 0 on success, 1 if some phases could not be changed.
(For more information about the phases concept, see hg help phases.)
Options:
-p, --public
set changeset phase to public
-d, --draft
set changeset phase to draft
-s, --secret
set changeset phase to secret
-f, --force
allow to move boundary backward
-r,--rev <REV[+]>
target revision
[+] marked option can be specified multiple times
tag
add one or more tags for the current or given revision:
hg tag [-f] [-l] [-m TEXT] [-d DATE] [-u USER] [-r REV] NAME...
Name a particular revision using <name>.
Tags are used to name particular revisions of the repository and are very useful to compare different
revisions, to go back to significant earlier versions or to mark branch points as releases, etc. Changing
an existing tag is normally disallowed; use -f/--force to override.
If no revision is given, the parent of the working directory is used.
To facilitate version control, distribution, and merging of tags, they are stored as a file named
".hgtags" which is managed similarly to other project files and can be hand-edited if necessary. This
also means that tagging creates a new commit. The file ".hg/localtags" is used for local tags (not shared
among repositories).
Tag commits are usually made at the head of a branch. If the parent of the working directory is not a
branch head, hg tag aborts; use -f/--force to force the tag commit to be based on a non-head changeset.
See hg help dates for a list of formats valid for -d/--date.
Since tag names have priority over branch names during revision lookup, using an existing branch name as
a tag name is discouraged.
Returns 0 on success.
Options:
-f, --force
force tag
-l, --local
make the tag local
-r,--rev <REV>
revision to tag
--remove
remove a tag
-e, --edit
invoke editor on commit messages
-m,--message <TEXT>
use text as commit message
-d,--date <DATE>
record the specified date as commit date
-u,--user <USER>
record the specified user as committer
tags
list repository tags:
hg tags
This lists both regular and local tags. When the -v/--verbose switch is used, a third column "local" is
printed for local tags. When the -q/--quiet switch is used, only the tag name is printed.
Template:
The following keywords are supported in addition to the common template keywords and functions such as
{tag}. See also hg help templates.
type String. local for local tags.
Returns 0 on success.
Options:
-T,--template <TEMPLATE>

File content management
annotate
show changeset information by line for each file:
hg annotate [-r REV] [-f] [-a] [-u] [-d] [-n] [-c] [-l] FILE...
List changes in files, showing the revision id responsible for each line.
This command is useful for discovering when a change was made and by whom.
If you include --file, --user, or --date, the revision number is suppressed unless you also include
--number.
Without the -a/--text option, annotate will avoid processing files it detects as binary. With -a,
annotate will annotate the file anyway, although the results will probably be neither useful nor
desirable.
Use -L/--line-range FILE,M:N options to filter the output to the lines from M to N in FILE. This option
is incompatible with --no-follow and cannot be combined with file pattern arguments. When combined with
--rev the line ranges refer to the state of the file at the requested revision.
Template:
The following keywords are supported in addition to the common template keywords and functions. See also
hg help templates.
lines List of lines with annotation data.
path String. Repository-absolute path of the specified file.
And each entry of {lines} provides the following sub-keywords in addition to {date}, {node}, {rev},
{user}, etc.
line String. Line content.
lineno Integer. Line number at that revision.
path String. Repository-absolute path of the file at that revision.
See hg help templates.operators for the list expansion syntax.
Returns 0 on success.
Options:
-r,--rev <REV>
annotate the specified revision
--follow

cat
output the current or given revision of files:
hg cat [OPTION]... FILE...
Print the specified files as they were at the given revision. If no revision is given, the parent of the
working directory is used.
Output may be to a file, in which case the name of the file is given using a template string. See hg help
templates. In addition to the common template keywords, the following formatting rules are supported:
%%
literal "%" character
%s
basename of file being printed
%d
dirname of file being printed, or '.' if in repository root
%p
root-relative path name of file being printed
%H
changeset hash (40 hexadecimal digits)

copy
mark files as copied for the next commit:
hg copy [OPTION]... (SOURCE... DEST | --forget DEST...)
Mark dest as having copies of source files. If dest is a directory, copies are put in that directory. If
dest is a file, the source must be a single file.
By default, this command copies the contents of files as they exist in the working directory. If invoked
with -A/--after, the operation is recorded, but no copying is performed.
To undo marking a destination file as copied, use --forget. With that option, all given (positional)
arguments are unmarked as copies. The destination file(s) will be left in place (still tracked). Note
that hg copy --forget behaves the same way as hg rename --forget.
This command takes effect with the next commit by default.
Returns 0 on success, 1 if errors are encountered.
Options:
--forget
unmark a destination file as copied
-A, --after
record a copy that has already occurred
--at-rev <REV>

[+] marked option can be specified multiple times
aliases: cp
diff
diff repository (or selected files):
hg diff [OPTION]... ([-c REV] | [--from REV1] [--to REV2]) [FILE]...
Show differences between revisions for the specified files.
Differences between files are shown using the unified diff format.
Note hg diff may generate unexpected results for merges, as it will default to comparing against the
working directory's first parent changeset if no revisions are specified. To diff against the
conflict regions, you can use --config diff.merge=yes.
By default, the working directory files are compared to its first parent. To see the differences from
another revision, use --from. To see the difference to another revision, use --to. For example, hg diff
--from .^ will show the differences from the working copy's grandparent to the working copy, hg diff --to
. will show the diff from the working copy to its parent (i.e. the reverse of the default), and hg diff
--from 1.0 --to 1.2 will show the diff between those two revisions.
Alternatively you can specify -c/--change with a revision to see the changes in that changeset relative
to its first parent (i.e. hg diff -c 42 is equivalent to hg diff --from 42^ --to 42)
Without the -a/--text option, diff will avoid generating diffs of files it detects as binary. With -a,
diff will generate a diff anyway, probably with undesirable results.
Use the -g/--git option to generate diffs in the git extended diff format. For more information, read hg
help diffs.
Examples:
• compare a file in the current working directory to its parent:
hg diff foo.c
• compare two historical versions of a directory, with rename info:
hg diff --git --from 1.0 --to 1.2 lib/
• get change stats relative to the last change on some date:
hg diff --stat --from "date('may 2')"
• diff all newly-added files that contain a keyword:
hg diff "set:added() and grep(GNU)"
• compare a revision and its parents:
hg diff -c 9353 # compare against first parent
hg diff --from 9353^ --to 9353 # same using revset syntax
hg diff --from 9353^2 --to 9353 # compare against the second parent
Returns 0 on success.

[+] marked option can be specified multiple times
grep
search for a pattern in specified files:
hg grep [--diff] [OPTION]... PATTERN [FILE]...
Search the working directory or revision history for a regular expression in the specified files for the
entire repository.
By default, grep searches the repository files in the working directory and prints the files where it
finds a match. To specify historical revisions instead of the working directory, use the --rev flag.
To search instead historical revision differences that contains a change in match status ("-" for a match
that becomes a non-match, or "+" for a non-match that becomes a match), use the --diff flag.
PATTERN can be any Python (roughly Perl-compatible) regular expression.
If no FILEs are specified and the --rev flag isn't supplied, all files in the working directory are
searched. When using the --rev flag and specifying FILEs, use the --follow argument to also follow the
specified FILEs across renames and copies.
Template:
The following keywords are supported in addition to the common template keywords and functions. See also
hg help templates.
change String. Character denoting insertion + or removal -. Available if --diff is specified.
lineno Integer. Line number of the match.
path String. Repository-absolute path of the file.
texts List of text chunks.
And each entry of {texts} provides the following sub-keywords.
matched
Boolean. True if the chunk matches the specified pattern.
text String. Chunk content.
See hg help templates.operators for the list expansion syntax.

bisect
subdivision search of changesets:
hg bisect [-gbsr] [-U] [-c CMD] [REV]
This command helps to find changesets which introduce problems. To use, mark the earliest changeset you
know exhibits the problem as bad, then mark the latest changeset which is free from the problem as good.
Bisect will update your working directory to a revision for testing (unless the -U/--noupdate option is
specified). Once you have performed tests, mark the working directory as good or bad, and bisect will
either update to another candidate changeset or announce that it has found the bad revision.
As a shortcut, you can also use the revision argument to mark a revision as good or bad without checking
it out first.
If you supply a command, it will be used for automatic bisection. The environment variable HG_NODE will
contain the ID of the changeset being tested. The exit status of the command will be used to mark
revisions as good or bad: status 0 means good, 125 means to skip the revision, 127 (command not found)
will abort the bisection, and any other non-zero exit status means the revision is bad.
Some examples:
• start a bisection with known bad revision 34, and good revision 12:
hg bisect --bad 34
hg bisect --good 12
• advance the current bisection by marking current revision as good or bad:
hg bisect --good
hg bisect --bad
• mark the current revision, or a known revision, to be skipped (e.g. if that revision is not usable
because of another issue):
hg bisect --skip
hg bisect --skip 23
• skip all revisions that do not touch directories foo or bar:
hg bisect --skip "!( file('path:foo') & file('path:bar') )"
• forget the current bisection:
hg bisect --reset
• use 'make && make tests' to automatically find the first broken revision:
hg bisect --reset
hg bisect --bad 34
hg bisect --good 12
hg bisect --command "make && make tests"
• see all changesets whose states are already known in the current bisection:
hg log -r "bisect(pruned)"
• see the changeset currently being bisected (especially useful if running with -U/--noupdate):
hg log -r "bisect(current)"
• see all changesets that took part in the current bisection:
hg log -r "bisect(range)"
• you can even get a nice graph:
hg log --graph -r "bisect(range)"
See hg help revisions.bisect for more about the bisect() predicate.
Returns 0 on success.
Options:
-r, --reset
reset bisect state
-g, --good
mark changeset good
-b, --bad
mark changeset bad
-s, --skip
skip testing changeset
-e, --extend
extend the bisect range
-c,--command <CMD>
use command to check changeset state
-U, --noupdate
do not update to target
heads
show branch heads:
hg heads [-ct] [-r STARTREV] [REV]...
With no arguments, show all open branch heads in the repository. Branch heads are changesets that have
no descendants on the same branch. They are where development generally takes place and are the usual
targets for update and merge operations.
If one or more REVs are given, only open branch heads on the branches associated with the specified
changesets are shown. This means that you can use hg heads . to see the heads on the currently
checked-out branch.
If -c/--closed is specified, also show branch heads marked closed (see hg commit --close-branch).
If STARTREV is specified, only those heads that are descendants of STARTREV will be displayed.
If -t/--topo is specified, named branch mechanics will be ignored and only topological heads (changesets
with no children) will be shown.
Returns 0 if matching heads are found, 1 if not.
Options:
-r,--rev <STARTREV>
show only heads which are descendants of STARTREV
-t, --topo
show topological heads only
-a, --active
show active branchheads only (DEPRECATED)
-c, --closed
show normal and closed branch heads
--style <STYLE>
display using template map file (DEPRECATED)
-T,--template <TEMPLATE>

identify
identify the working directory or specified revision:
hg identify [-nibtB] [-r REV] [SOURCE]
Print a summary identifying the repository state at REV using one or two parent hash identifiers,
followed by a "+" if the working directory has uncommitted changes, the branch name (if not default), a
list of tags, and a list of bookmarks.
When REV is not given, print a summary of the current state of the repository including the working
directory. Specify -r. to get information of the working directory parent without scanning uncommitted
changes.
Specifying a path to a repository root or Mercurial bundle will cause lookup to operate on that
repository/bundle.
Template:
The following keywords are supported in addition to the common template keywords and functions. See also
hg help templates.
dirty String. Character + denoting if the working directory has uncommitted changes.
id String. One or two nodes, optionally followed by +.
parents
List of strings. Parent nodes of the changeset.
Examples:
• generate a build identifier for the working directory:
hg id --id > build-id.dat
• find the revision corresponding to a tag:
hg id -n -r 1.3
• check the most recent revision of a remote repository:
hg id -r tip https://www.mercurial-scm.org/repo/hg/
See hg log for generating more information about specific revisions, including full hash identifiers.
Returns 0 if successful.
Options:
-r,--rev <REV>
identify the specified revision
-n, --num
show local revision number
-i, --id
show global revision id
-b, --branch
show branch
-t, --tags

aliases: id
log
show revision history of entire repository or files:
hg log [OPTION]... [FILE]
Print the revision history of the specified files or the entire project.
If no revision range is specified, the default is tip:0 unless --follow is set.
File history is shown without following rename or copy history of files. Use -f/--follow with a filename
to follow history across renames and copies. --follow without a filename will only show ancestors of the
starting revisions. The starting revisions can be specified by -r/--rev, which default to the working
directory parent.
By default this command prints revision number and changeset id, tags, non-trivial parents, user, date
and time, and a summary for each commit. When the -v/--verbose switch is used, the list of changed files
and full commit message are shown.
With --graph the revisions are shown as an ASCII art DAG with the most recent changeset at the top. 'o'
is a changeset, '@' is a working directory parent, '%' is a changeset involved in an unresolved merge
conflict, '_' closes a branch, 'x' is obsolete, '*' is unstable, and '+' represents a fork where the
changeset from the lines below is a parent of the 'o' merge on the same line. Paths in the DAG are
represented with '|', '/' and so forth. ':' in place of a '|' indicates one or more revisions in a path
are omitted.
Use -L/--line-range FILE,M:N options to follow the history of lines from M to N in FILE. With -p/--patch
only diff hunks affecting specified line range will be shown. This option requires --follow; it can be
specified multiple times. Currently, this option is not compatible with --graph. This option is
experimental.
Note hg log --patch may generate unexpected diff output for merge changesets, as it will only compare
the merge changeset against its first parent. Also, only files different from BOTH parents will
appear in files:.
Note For performance reasons, hg log FILE may omit duplicate changes made on branches and will not show
removals or mode changes. To see all such changes, use the --removed switch.
Note The history resulting from -L/--line-range options depends on diff options; for instance if
white-spaces are ignored, respective changes with only white-spaces in specified line range will
not be listed.
Some examples:
• changesets with full descriptions and file lists:
hg log -v
• changesets ancestral to the working directory:
hg log -f
• last 10 commits on the current branch:
hg log -l 10 -b .
• changesets showing all modifications of a file, including removals:
hg log --removed file.c
• all changesets that touch a directory, with diffs, excluding merges:
hg log -Mp lib/
• all revision numbers that match a keyword:
hg log -k bug --template "{rev}\n"
• the full hash identifier of the working directory parent:
hg log -r . --template "{node}\n"
• list available log templates:
hg log -T list
• check if a given changeset is included in a tagged release:
hg log -r "a21ccf and ancestor(1.9)"
• find all changesets by some user in a date range:
hg log -k alice -d "may 2008 to jul 2008"
• summary of all changesets after the last tag:
hg log -r "last(tagged())::" --template "{desc|firstline}\n"
• changesets touching lines 13 to 23 for file.c:
hg log -L file.c,13:23
• changesets touching lines 13 to 23 for file.c and lines 2 to 6 of main.c with patch:
hg log -L file.c,13:23 -L main.c,2:6 -p
See hg help dates for a list of formats valid for -d/--date.
See hg help revisions for more about specifying and ordering revisions.
See hg help templates for more about pre-packaged styles and specifying custom templates. The default
template used by the log command can be customized via the command-templates.log configuration setting.
Returns 0 on success.

parents
show the parents of the working directory or revision (DEPRECATED):
hg parents [-r REV] [FILE]
Print the working directory's parent revisions. If a revision is given via -r/--rev, the parent of that
revision will be printed. If a file argument is given, the revision in which the file was last changed
(before the working directory revision or the argument to --rev if given) is printed.
This command is equivalent to:
hg log -r "p1()+p2()" or
hg log -r "p1(REV)+p2(REV)" or
hg log -r "max(::p1() and file(FILE))+max(::p2() and file(FILE))" or
hg log -r "max(::p1(REV) and file(FILE))+max(::p2(REV) and file(FILE))"
See hg summary and hg help revsets for related information.
Returns 0 on success.
Options:
-r,--rev <REV>
show parents of the specified revision
--style <STYLE>
display using template map file (DEPRECATED)
-T,--template <TEMPLATE>
display with template
tip
show the tip revision (DEPRECATED):
hg tip [-p] [-g]
The tip revision (usually just called the tip) is the changeset most recently added to the repository
(and therefore the most recently changed head).
If you have just made a commit, that commit will be the tip. If you have just pulled changes from another
repository, the tip of that repository becomes the current tip. The "tip" tag is special and cannot be
renamed or assigned to a different changeset.
This command is deprecated, please use hg heads instead.
Returns 0 on success.
Options:
-p, --patch
show patch
-g, --git
use git extended diff format
--style <STYLE>

Working directory management
add
add the specified files on the next commit:
hg add [OPTION]... [FILE]...
Schedule files to be version controlled and added to the repository.
The files will be added to the repository at the next commit. To undo an add before that, see hg forget.
If no names are given, add all files to the repository (except files matching .hgignore).
Examples:
• New (unknown) files are added automatically by hg add:
$ ls
foo.c
$ hg status
? foo.c
$ hg add
adding foo.c
$ hg status
A foo.c
• Specific files to be added can be specified:
$ ls
bar.c foo.c
$ hg status
? bar.c
? foo.c
$ hg add bar.c
$ hg status
A bar.c
? foo.c
Returns 0 if all files are successfully added.
Options:
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
-S, --subrepos
recurse into subrepositories
-n, --dry-run
do not perform actions, just print output
[+] marked option can be specified multiple times
addremove
add all new files, delete all missing files:
hg addremove [OPTION]... [FILE]...
Add all new files and remove all missing files from the repository.
Unless names are given, new files are ignored if they match any of the patterns in .hgignore. As with
add, these changes take effect at the next commit.
Use the -s/--similarity option to detect renamed files. This option takes a percentage between 0
(disabled) and 100 (files must be identical) as its parameter. With a parameter greater than 0, this
compares every removed file with every added file and records those similar enough as renames. Detecting
renamed files this way can be expensive. After using this option, hg status -C can be used to check which
files were identified as moved or renamed. If not specified, -s/--similarity defaults to 100 and only
renames of identical files are detected.
Examples:
• A number of files (bar.c and foo.c) are new, while foobar.c has been removed (without using hg
remove) from the repository:
$ ls
bar.c foo.c
$ hg status
! foobar.c
? bar.c
? foo.c
$ hg addremove
adding bar.c
adding foo.c
removing foobar.c
$ hg status
A bar.c
A foo.c
R foobar.c
• A file foobar.c was moved to foo.c without using hg rename. Afterwards, it was edited slightly:
$ ls
foo.c
$ hg status
! foobar.c
? foo.c
$ hg addremove --similarity 90
removing foobar.c
adding foo.c
recording removal of foobar.c as rename to foo.c (94% similar)
$ hg status -C
A foo.c
foobar.c
R foobar.c
Returns 0 if all files are successfully added.
Options:
-s,--similarity <SIMILARITY>
guess renamed files by similarity (0<=s<=100)
-S, --subrepos
recurse into subrepositories
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
-n, --dry-run
do not perform actions, just print output
[+] marked option can be specified multiple times
files
list tracked files:
hg files [OPTION]... [FILE]...
Print files under Mercurial control in the working directory or specified revision for given files
(excluding removed files). Files can be specified as filenames or filesets.
If no files are given to match, this command prints the names of all files under Mercurial control.
Template:
The following keywords are supported in addition to the common template keywords and functions. See also
hg help templates.
flags String. Character denoting file's symlink and executable bits.
path String. Repository-absolute path of the file.
size Integer. Size of the file in bytes.
Examples:
• list all files under the current directory:
hg files .
• shows sizes and flags for current revision:
hg files -vr .
• list all files named README:
hg files -I "**/README"
• list all binary files:
hg files "set:binary()"
• find files containing a regular expression:
hg files "set:grep('bob')"
• search tracked file contents with xargs and grep:
hg files -0 | xargs -0 grep foo
See hg help patterns and hg help filesets for more information on specifying file patterns.
Returns 0 if a match is found, 1 otherwise.
Options:
-r,--rev <REV>
search the repository as it is in REV
-0, --print0
end filenames with NUL, for use with xargs
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
-T,--template <TEMPLATE>
display with template
-S, --subrepos
recurse into subrepositories
[+] marked option can be specified multiple times
forget
forget the specified files on the next commit:
hg forget [OPTION]... FILE...
Mark the specified files so they will no longer be tracked after the next commit.
This only removes files from the current branch, not from the entire project history, and it does not
delete them from the working directory.
To delete the file from the working directory, see hg remove.
To undo a forget before the next commit, see hg add.
Examples:
• forget newly-added binary files:
hg forget "set:added() and binary()"
• forget files that would be excluded by .hgignore:
hg forget "set:hgignore()"
Returns 0 on success.
Options:
-i, --interactive
use interactive mode
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
-n, --dry-run
do not perform actions, just print output
[+] marked option can be specified multiple times
locate
locate files matching specific patterns (DEPRECATED):
hg locate [OPTION]... [PATTERN]...
Print files under Mercurial control in the working directory whose names match the given patterns.
By default, this command searches all directories in the working directory. To search just the current
directory and its subdirectories, use "--include .".
If no patterns are given to match, this command prints the names of all files under Mercurial control in
the working directory.
If you want to feed the output of this command into the "xargs" command, use the -0 option to both this
command and "xargs". This will avoid the problem of "xargs" treating single filenames that contain
whitespace as multiple filenames.
See hg help files for a more versatile command.
Returns 0 if a match is found, 1 otherwise.
Options:
-r,--rev <REV>
search the repository as it is in REV
-0, --print0
end filenames with NUL, for use with xargs
-f, --fullpath
print complete paths from the filesystem root
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
[+] marked option can be specified multiple times
purge
removes files not tracked by Mercurial:
hg purge [OPTION]... [DIR]...
Delete files not known to Mercurial. This is useful to test local and uncommitted changes in an
otherwise-clean source tree.
This means that purge will delete the following by default:
• Unknown files: files marked with "?" by hg status
• Empty directories: in fact Mercurial ignores directories unless they contain files under source control
management
But it will leave untouched:
• Modified and unmodified tracked files
• Ignored files (unless -i or --all is specified)
• New files added to the repository (with hg add)
The --files and --dirs options can be used to direct purge to delete only files, only directories, or
both. If neither option is given, both will be deleted.
If directories are given on the command line, only files in these directories are considered.
Be careful with purge, as you could irreversibly delete some files you forgot to add to the repository.
If you only want to print the list of files that this program would delete, use the --print option.
Options:
-a, --abort-on-err
abort if an error occurs
--all purge ignored files too
-i, --ignored
purge only ignored files
--dirs purge empty directories
--files
purge files
-p, --print
print filenames instead of deleting them
-0, --print0
end filenames with NUL, for use with xargs (implies -p/--print)
--confirm
ask before permanently deleting files
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
[+] marked option can be specified multiple times
aliases: clean
remove
remove the specified files on the next commit:
hg remove [OPTION]... FILE...
Schedule the indicated files for removal from the current branch.
This command schedules the files to be removed at the next commit. To undo a remove before that, see hg
revert. To undo added files, see hg forget.
-A/--after can be used to remove only files that have already been deleted, -f/--force can be used to
force deletion, and -Af can be used to remove files from the next revision without deleting them from the
working directory.
The following table details the behavior of remove for different file states (columns) and option
combinations (rows). The file states are Added [A], Clean [C], Modified [M] and Missing [!] (as reported
by hg status). The actions are Warn, Remove (from branch) and Delete (from disk):
┌───────────┬───┬────┬────┬───┐
│ opt/state │ A │ C │ M │ ! │
├───────────┼───┼────┼────┼───┤
│ none │ W │ RD │ W │ R │
├───────────┼───┼────┼────┼───┤
│ -f │ R │ RD │ RD │ R │
├───────────┼───┼────┼────┼───┤
│ -A │ W │ W │ W │ R │
├───────────┼───┼────┼────┼───┤
│ -Af │ R │ R │ R │ R │
└───────────┴───┴────┴────┴───┘
Note hg remove never deletes files in Added [A] state from the working directory, not even if --force
is specified.
Returns 0 on success, 1 if any warnings encountered.
Options:
-A, --after
record delete for missing files
-f, --force
forget added files, delete modified files
-S, --subrepos
recurse into subrepositories
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
-n, --dry-run
do not perform actions, just print output
[+] marked option can be specified multiple times
aliases: rm
rename
rename files; equivalent of copy + remove:
hg rename [OPTION]... SOURCE... DEST
Mark dest as copies of sources; mark sources for deletion. If dest is a directory, copies are put in that
directory. If dest is a file, there can only be one source.
By default, this command copies the contents of files as they exist in the working directory. If invoked
with -A/--after, the operation is recorded, but no copying is performed.
To undo marking a destination file as renamed, use --forget. With that option, all given (positional)
arguments are unmarked as renames. The destination file(s) will be left in place (still tracked). The
source file(s) will not be restored. Note that hg rename --forget behaves the same way as hg copy
--forget.
This command takes effect with the next commit by default.
Returns 0 on success, 1 if errors are encountered.
Options:
--forget
unmark a destination file as renamed
-A, --after
record a rename that has already occurred
--at-rev <REV>
(un)mark renames in the given revision (EXPERIMENTAL)
-f, --force
forcibly move over an existing managed file
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
-n, --dry-run
do not perform actions, just print output
[+] marked option can be specified multiple times
aliases: move mv
resolve
redo merges or set/view the merge status of files:
hg resolve [OPTION]... [FILE]...
Merges with unresolved conflicts are often the result of non-interactive merging using the internal:merge
configuration setting, or a command-line merge tool like diff3. The resolve command is used to manage the
files involved in a merge, after hg merge has been run, and before hg commit is run (i.e. the working
directory must have two parents). See hg help merge-tools for information on configuring merge tools.
The resolve command can be used in the following ways:
• hg resolve [--re-merge] [--tool TOOL] FILE...: attempt to re-merge the specified files, discarding any
previous merge attempts. Re-merging is not performed for files already marked as resolved. Use --all/-a
to select all unresolved files. --tool can be used to specify the merge tool used for the given files.
It overrides the HGMERGE environment variable and your configuration files. Previous file contents are
saved with a .orig suffix.
• hg resolve -m [FILE]: mark a file as having been resolved (e.g. after having manually fixed-up the
files). The default is to mark all unresolved files.
• hg resolve -u [FILE]...: mark a file as unresolved. The default is to mark all resolved files.
• hg resolve -l: list files which had or still have conflicts. In the printed list, U = unresolved and R
= resolved. You can use set:unresolved() or set:resolved() to filter the list. See hg help filesets
for details.
Note Mercurial will not let you commit files with unresolved merge conflicts. You must use hg resolve
-m ... before you can commit after a conflicting merge.
Template:
The following keywords are supported in addition to the common template keywords and functions. See also
hg help templates.
mergestatus
String. Character denoting merge conflicts, U or R.
path String. Repository-absolute path of the file.
Returns 0 on success, 1 if any files fail a resolve attempt.
Options:
-a, --all
select all unresolved files
-l, --list
list state of files needing merge
-m, --mark
mark files as resolved
-u, --unmark
mark files as unresolved
-n, --no-status
hide status prefix
--re-merge
re-merge files
-t,--tool <TOOL>

-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
-T,--template <TEMPLATE>
display with template
[+] marked option can be specified multiple times
revert
restore files to their checkout state:
hg revert [OPTION]... [-r REV] [NAME]...
Note To check out earlier revisions, you should use hg update REV. To cancel an uncommitted merge (and
lose your changes), use hg merge --abort.
With no revision specified, revert the specified files or directories to the contents they had in the
parent of the working directory. This restores the contents of files to an unmodified state and
unschedules adds, removes, copies, and renames. If the working directory has two parents, you must
explicitly specify a revision.
Using the -r/--rev or -d/--date options, revert the given files or directories to their states as of a
specific revision. Because revert does not change the working directory parents, this will cause these
files to appear modified. This can be helpful to "back out" some or all of an earlier change. See hg
backout for a related method.
Modified files are saved with a .orig suffix before reverting. To disable these backups, use
--no-backup. It is possible to store the backup files in a custom directory relative to the root of the
repository by setting the ui.origbackuppath configuration option.
See hg help dates for a list of formats valid for -d/--date.
See hg help backout for a way to reverse the effect of an earlier changeset.
Returns 0 on success.
Options:
-a, --all
revert all changes when no arguments given
-d,--date <DATE>
tipmost revision matching date
-r,--rev <REV>
revert to the specified revision
-C, --no-backup
do not save backup copies of files
-i, --interactive
interactively select the changes
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
-n, --dry-run
do not perform actions, just print output
[+] marked option can be specified multiple times
root
print the root (top) of the current working directory:
hg root
Print the root directory of the current repository.
Template:
The following keywords are supported in addition to the common template keywords and functions. See also
hg help templates.
hgpath String. Path to the .hg directory.
storepath
String. Path to the directory holding versioned data.
Returns 0 on success.
Options:
-T,--template <TEMPLATE>
display with template
shelve
save and set aside changes from the working directory:
hg shelve [OPTION]... [FILE]...
Shelving takes files that "hg status" reports as not clean, saves the modifications to a bundle (a
shelved change), and reverts the files so that their state in the working directory becomes clean.
To restore these changes to the working directory, using "hg unshelve"; this will work even if you switch
to a different commit.
When no files are specified, "hg shelve" saves all not-clean files. If specific files or directories are
named, only changes to those files are shelved.
In bare shelve (when no files are specified, without interactive, include and exclude option), shelving
remembers information if the working directory was on newly created branch, in other words working
directory was on different branch than its first parent. In this situation unshelving restores branch
information to the working directory.
Each shelved change has a name that makes it easier to find later. The name of a shelved change defaults
to being based on the active bookmark, or if there is no active bookmark, the current named branch. To
specify a different name, use --name.
To see a list of existing shelved changes, use the --list option. For each shelved change, this will
print its name, age, and description; use --patch or --stat for more details.
To delete specific shelved changes, use --delete. To delete all shelved changes, use --cleanup.
Options:
-A, --addremove
mark new/missing files as added/removed before shelving
-u, --unknown
store unknown files in the shelve
--cleanup
delete all shelved changes
--date <DATE>
shelve with the specified commit date
-d, --delete
delete the named shelved change(s)
-e, --edit
invoke editor on commit messages
-k, --keep
shelve, but keep changes in the working directory
-l, --list
list current shelves
-m,--message <TEXT>
use text as shelve message
-n,--name <NAME>
use the given name for the shelved commit
-p, --patch
output patches for changes (provide the names of the shelved changes as positional arguments)
-i, --interactive
interactive mode
--stat output diffstat-style summary of changes (provide the names of the shelved changes as positional
arguments)
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
[+] marked option can be specified multiple times
status
show changed files in the working directory:
hg status [OPTION]... [FILE]...
Show status of files in the repository. If names are given, only files that match are shown. Files that
are clean or ignored or the source of a copy/move operation, are not listed unless -c/--clean,
-i/--ignored, -C/--copies or -A/--all are given. Unless options described with "show only ..." are
given, the options -mardu are used.
Option -q/--quiet hides untracked (unknown and ignored) files unless explicitly requested with
-u/--unknown or -i/--ignored.
Note hg status may appear to disagree with diff if permissions have changed or a merge has occurred.
The standard diff format does not report permission changes and diff only reports changes relative
to one merge parent.
If one revision is given, it is used as the base revision. If two revisions are given, the differences
between them are shown. The --change option can also be used as a shortcut to list the changed files of a
revision from its first parent.
The codes used to show the status of files are:
M = modified
A = added
R = removed
C = clean
! = missing (deleted by non-hg command, but still tracked)
? = not tracked
I = ignored
= origin of the previous file (with --copies)
The -t/--terse option abbreviates the output by showing only the directory name if all the files in it
share the same status. The option takes an argument indicating the statuses to abbreviate: 'm' for
'modified', 'a' for 'added', 'r' for 'removed', 'd' for 'deleted', 'u' for 'unknown', 'i' for 'ignored'
and 'c' for clean.
It abbreviates only those statuses which are passed. Note that clean and ignored files are not displayed
with '--terse ic' unless the -c/--clean and -i/--ignored options are also used.
The -v/--verbose option shows information when the repository is in an unfinished merge, shelve, rebase
state etc. You can have this behavior turned on by default by enabling the commands.status.verbose
option.
You can skip displaying some of these states by setting commands.status.skipstates to one or more of:
'bisect', 'graft', 'histedit', 'merge', 'rebase', or 'unshelve'.
Template:
The following keywords are supported in addition to the common template keywords and functions. See also
hg help templates.
path String. Repository-absolute path of the file.
source String. Repository-absolute path of the file originated from. Available if --copies is specified.
status String. Character denoting file's status.
Examples:
• show changes in the working directory relative to a changeset:
hg status --rev 9353
• show changes in the working directory relative to the current directory (see hg help patterns for more
information):
hg status re:
• show all changes including copies in an existing changeset:
hg status --copies --change 9353
• get a NUL separated list of added files, suitable for xargs:
hg status -an0
• show more information about the repository status, abbreviating added, removed, modified, deleted, and
untracked paths:
hg status -v -t mardu
Returns 0 on success.
Options:
-A, --all
show status of all files
-m, --modified
show only modified files
-a, --added
show only added files
-r, --removed
show only removed files
-d, --deleted
show only missing files
-c, --clean
show only files without changes
-u, --unknown
show only unknown (not tracked) files
-i, --ignored
show only ignored files
-n, --no-status

-t,--terse <VALUE>
show the terse output (EXPERIMENTAL) (default: nothing)
-C, --copies
show source of copied files (DEFAULT: ui.statuscopies)
-0, --print0
end filenames with NUL, for use with xargs
--rev <REV[+]>
show difference from revision
--change <REV>
list the changed files of a revision
-I,--include <PATTERN[+]>

summary
summarize working directory state:
hg summary [--remote]
This generates a brief summary of the working directory state, including parents, branch, commit status,
phase and available updates.
With the --remote option, this will check the default paths for incoming and outgoing changes. This can
be time-consuming.
Returns 0 on success.
Options:
--remote
check for push and pull
aliases: sum
unshelve
restore a shelved change to the working directory:
hg unshelve [OPTION]... [[-n] SHELVED]
This command accepts an optional name of a shelved change to restore. If none is given, the most recent
shelved change is used.
If a shelved change is applied successfully, the bundle that contains the shelved changes is moved to a
backup location (.hg/shelve-backup).
Since you can restore a shelved change on top of an arbitrary commit, it is possible that unshelving will
result in a conflict between your changes and the commits you are unshelving onto. If this occurs, you
must resolve the conflict, then use --continue to complete the unshelve operation. (The bundle will not
be moved until you successfully complete the unshelve.)
(Alternatively, you can use --abort to abandon an unshelve that causes a conflict. This reverts the
unshelved changes, and leaves the bundle in place.)
If bare shelved change (without interactive, include and exclude option) was done on newly created branch
it would restore branch information to the working directory.
After a successful unshelve, the shelved changes are stored in a backup directory. Only the N most recent
backups are kept. N defaults to 10 but can be overridden using the shelve.maxbackups configuration
option.
Timestamp in seconds is used to decide order of backups. More than maxbackups backups are kept, if same
timestamp prevents from deciding exact order of them, for safety.
Selected changes can be unshelved with --interactive flag. The working directory is updated with the
selected changes, and only the unselected changes remain shelved. Note: The whole shelve is applied to
working directory first before running interactively. So, this will bring up all the conflicts between
working directory and the shelve, irrespective of which changes will be unshelved.
Options:
-a, --abort
abort an incomplete unshelve operation
-c, --continue
continue an incomplete unshelve operation
-i, --interactive
use interactive mode (EXPERIMENTAL)
-k, --keep
keep shelve after unshelving
-n,--name <NAME>
restore shelved change with given name
-t,--tool <VALUE>
specify merge tool
--date <DATE>
set date for temporary commits (DEPRECATED)
update
update working directory (or switch revisions):
hg update [-C|-c|-m] [-d DATE] [[-r] REV]
Update the repository's working directory to the specified changeset. If no changeset is specified,
update to the tip of the current named branch and move the active bookmark (see hg help bookmarks).
Update sets the working directory's parent revision to the specified changeset (see hg help parents).
If the changeset is not a descendant or ancestor of the working directory's parent and there are
uncommitted changes, the update is aborted. With the -c/--check option, the working directory is checked
for uncommitted changes; if none are found, the working directory is updated to the specified changeset.
The -C/--clean, -c/--check, and -m/--merge options control what happens if the working directory contains
uncommitted changes. At most of one of them can be specified.
1. If no option is specified, and if the requested changeset is an ancestor or descendant of the working
directory's parent, the uncommitted changes are merged into the requested changeset and the merged
result is left uncommitted. If the requested changeset is not an ancestor or descendant (that is, it
is on another branch), the update is aborted and the uncommitted changes are preserved.
2. With the -m/--merge option, the update is allowed even if the requested changeset is not an ancestor
or descendant of the working directory's parent.
3. With the -c/--check option, the update is aborted and the uncommitted changes are preserved.
4. With the -C/--clean option, uncommitted changes are discarded and the working directory is updated to
the requested changeset.
To cancel an uncommitted merge (and lose your changes), use hg merge --abort.
Use null as the changeset to remove the working directory (like hg clone -U).
If you want to revert just one file to an older revision, use hg revert [-r REV] NAME.
See hg help dates for a list of formats valid for -d/--date.
Returns 0 on success, 1 if there are unresolved files.
Options:
-C, --clean
discard uncommitted changes (no backup)
-c, --check

Change import/export
archive
create an unversioned archive of a repository revision:
hg archive [OPTION]... DEST
By default, the revision used is the parent of the working directory; use -r/--rev to specify a different
revision.
The archive type is automatically detected based on file extension (to override, use -t/--type).
Examples:
• create a zip file containing the 1.0 release:
hg archive -r 1.0 project-1.0.zip
• create a tarball excluding .hg files:
hg archive project.tar.gz -X ".hg*"
Valid types are:
files
a directory full of files (default)
tar
tar archive, uncompressed
tbz2
tar archive, compressed using bzip2
tgz
tar archive, compressed using gzip
txz
tar archive, compressed using lzma (only in Python 3)
uzip
zip archive, uncompressed
zip
zip archive, compressed using deflate
The exact name of the destination archive or directory is given using a format string; see hg help export
for details.
Each member added to an archive file has a directory prefix prepended. Use -p/--prefix to specify a
format string for the prefix. The default is the basename of the archive, with suffixes removed.
Returns 0 on success.
Options:
--no-decode
do not pass files through decoders
-p,--prefix <PREFIX>
directory prefix for files in archive
-r,--rev <REV>

recurse into subrepositories
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
[+] marked option can be specified multiple times
bundle
create a bundle file:
hg bundle [-f] [-t BUNDLESPEC] [-a] [-r REV]... [--base REV]... FILE [DEST]...
Generate a bundle file containing data to be transferred to another repository.
To create a bundle containing all changesets, use -a/--all (or --base null). Otherwise, hg assumes the
destination will have all the nodes you specify with --base parameters. Otherwise, hg will assume the
repository has all the nodes in destination, or default-push/default if no destination is specified,
where destination is the repositories you provide through DEST option.
You can change bundle format with the -t/--type option. See hg help bundlespec for documentation on this
format. By default, the most appropriate format is used and compression defaults to bzip2.
The bundle file can then be transferred using conventional means and applied to another repository with
the unbundle or pull command. This is useful when direct push and pull are not available or when
exporting an entire repository is undesirable.
Applying bundles preserves all changeset contents including permissions, copy/rename information, and
revision history.
Returns 0 on success, 1 if no changes found.
Options:
--exact
compute the base from the revision specified
-f, --force
run even when the destination is unrelated
-r,--rev <REV[+]>
a changeset intended to be added to the destination
-b,--branch <BRANCH[+]>
a specific branch you would like to bundle
--base <REV[+]>
a base changeset assumed to be available at the destination
-a, --all
bundle all changesets in the repository
-t,--type <TYPE>
bundle compression type to use (default: bzip2)
-e,--ssh <CMD>
specify ssh command to use
--remotecmd <CMD>
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
[+] marked option can be specified multiple times
export
dump the header and diffs for one or more changesets:
hg export [OPTION]... [-o OUTFILESPEC] [-r] [REV]...
Print the changeset header and diffs for one or more revisions. If no revision is given, the parent of
the working directory is used.
The information shown in the changeset header is: author, date, branch name (if non-default), changeset
hash, parent(s) and commit comment.
Note hg export may generate unexpected diff output for merge changesets, as it will compare the merge
changeset against its first parent only.
Output may be to a file, in which case the name of the file is given using a template string. See hg help
templates. In addition to the common template keywords, the following formatting rules are supported:
%%
literal "%" character
%H
changeset hash (40 hexadecimal digits)
%N
number of patches being generated
%R
changeset revision number
%b
basename of the exporting repository
%h
short-form changeset hash (12 hexadecimal digits)
%m
first line of the commit message (only alphanumeric characters)
%n
zero-padded sequence number, starting at 1
%r
zero-padded changeset revision number
\
literal "" character
Without the -a/--text option, export will avoid generating diffs of files it detects as binary. With -a,
export will generate a diff anyway, probably with undesirable results.
With -B/--bookmark changesets reachable by the given bookmark are selected.
Use the -g/--git option to generate diffs in the git extended diff format. See hg help diffs for more
information.
With the --switch-parent option, the diff will be against the second parent. It can be useful to review a
merge.
Template:
The following keywords are supported in addition to the common template keywords and functions. See also
hg help templates.
diff String. Diff content.
parents
List of strings. Parent nodes of the changeset.
Examples:
• use export and import to transplant a bugfix to the current branch:
hg export -r 9353 | hg import -
• export all the changesets between two revisions to a file with rename information:
hg export --git -r 123:150 > changes.txt
• split outgoing changes into a series of patches with descriptive names:
hg export -r "outgoing()" -o "%n-%m.patch"
Returns 0 on success.
Options:
-B,--bookmark <BOOKMARK>
export changes only reachable by given bookmark
-o,--output <FORMAT>
print output to file with formatted name
--switch-parent
diff against the second parent
-r,--rev <REV[+]>
revisions to export
-a, --text
treat all files as text
-g, --git
use git extended diff format (DEFAULT: diff.git)
--binary
generate binary diffs in git mode (default)
--nodates
omit dates from diff headers
-T,--template <TEMPLATE>
display with template
[+] marked option can be specified multiple times
import
import an ordered set of patches:
hg import [OPTION]... PATCH...
Import a list of patches and commit them individually (unless --no-commit is specified).
To read a patch from standard input (stdin), use "-" as the patch name. If a URL is specified, the patch
will be downloaded from there.
Import first applies changes to the working directory (unless --bypass is specified), import will abort
if there are outstanding changes.
Use --bypass to apply and commit patches directly to the repository, without affecting the working
directory. Without --exact, patches will be applied on top of the working directory parent revision.
You can import a patch straight from a mail message. Even patches as attachments work (to use the body
part, it must have type text/plain or text/x-patch). From and Subject headers of email message are used
as default committer and commit message. All text/plain body parts before first diff are added to the
commit message.
If the imported patch was generated by hg export, user and description from patch override values from
message headers and body. Values given on command line with -m/--message and -u/--user override these.
If --exact is specified, import will set the working directory to the parent of each patch before
applying it, and will abort if the resulting changeset has a different ID than the one recorded in the
patch. This will guard against various ways that portable patch formats and mail systems might fail to
transfer Mercurial data or metadata. See hg bundle for lossless transmission.
Use --partial to ensure a changeset will be created from the patch even if some hunks fail to apply.
Hunks that fail to apply will be written to a <target-file>.rej file. Conflicts can then be resolved by
hand before hg commit --amend is run to update the created changeset. This flag exists to let people
import patches that partially apply without losing the associated metadata (author, date, description,
...).
Note When no hunks apply cleanly, hg import --partial will create an empty changeset, importing only
the patch metadata.
With -s/--similarity, hg will attempt to discover renames and copies in the patch in the same way as hg
addremove.
It is possible to use external patch programs to perform the patch by setting the ui.patch configuration
option. For the default internal tool, the fuzz can also be configured via patch.fuzz. See hg help
config for more information about configuration files and how to use these options.
See hg help dates for a list of formats valid for -d/--date.
Examples:
• import a traditional patch from a website and detect renames:
hg import -s 80 http://example.com/bugfix.patch
• import a changeset from an hgweb server:
hg import https://www.mercurial-scm.org/repo/hg/rev/5ca8c111e9aa
• import all the patches in an Unix-style mbox:
hg import incoming-patches.mbox
• import patches from stdin:
hg import -
• attempt to exactly restore an exported changeset (not always possible):
hg import --exact proposed-fix.patch
• use an external tool to apply a patch which is too fuzzy for the default internal tool.
hg import --config ui.patch="patch --merge" fuzzy.patch
• change the default fuzzing from 2 to a less strict 7
hg import --config ui.fuzz=7 fuzz.patch
Returns 0 on success, 1 on partial success (see --partial).
Options:
-p,--strip <NUM>
directory strip option for patch. This has the same meaning as the corresponding patch option
(default: 1)
-b,--base <PATH>
base path (DEPRECATED)
--secret
use the secret phase for committing
-e, --edit
invoke editor on commit messages
-f, --force
skip check for outstanding uncommitted changes (DEPRECATED)
--no-commit
don't commit, just update the working directory
--bypass
apply patch without touching the working directory
--partial
commit even if some hunks fail
--exact
abort if patch would apply lossily
--prefix <DIR>
apply patch to subdirectory
--import-branch
use any branch information in patch (implied by --exact)
-m,--message <TEXT>
use text as commit message
-l,--logfile <FILE>
read commit message from file
-d,--date <DATE>
record the specified date as commit date
-u,--user <USER>
record the specified user as committer
-s,--similarity <SIMILARITY>
guess renamed files by similarity (0<=s<=100)
aliases: patch
unbundle
apply one or more bundle files:
hg unbundle [-u] FILE...
Apply one or more bundle files generated by hg bundle.
Returns 0 on success, 1 if an update has unresolved files.
Options:
-u, --update
update to new branch head if changesets were unbundled
Repository maintenance
admin::verify
verify the integrity of the repository:
hg admin::verify
Alternative UI to hg verify with a lot more control over the verification process and better error
reporting.
Options:
-c,--check <CHECK[+]>
add a check
-o,--option <OPTION[+]>
pass an option to a check
[+] marked option can be specified multiple times
manifest
output the current or given revision of the project manifest:
hg manifest [-r REV]
Print a list of version controlled files for the given revision. If no revision is given, the first
parent of the working directory is used, or the null revision if no revision is checked out.
With -v, print file permissions, symlink and executable bits. With --debug, print file revision hashes.
If option --all is specified, the list of all files from all revisions is printed. This includes deleted
and renamed files.
Returns 0 on success.
Options:
-r,--rev <REV>
revision to display
--all list files from all revisions
-T,--template <TEMPLATE>
display with template
recover
roll back an interrupted transaction:
hg recover
Recover from an interrupted commit or pull.
This command tries to fix the repository status after an interrupted operation. It should only be
necessary when Mercurial suggests it.
Returns 0 if successful, 1 if nothing to recover or verify fails.
Options:
--verify
run hg verify after successful recover
rollback
roll back the last transaction (DANGEROUS) (DEPRECATED):
hg rollback
Please use hg commit --amend instead of rollback to correct mistakes in the last commit.
This command should be used with care. There is only one level of rollback, and there is no way to undo a
rollback. It will also restore the dirstate at the time of the last transaction, losing any dirstate
changes since that time. This command does not alter the working directory.
Transactions are used to encapsulate the effects of all commands that create new changesets or propagate
existing changesets into a repository.
For example, the following commands are transactional, and their effects can be rolled back:
• commit
• import
• pull
• push (with this repository as the destination)
• unbundle
To avoid permanent data loss, rollback will refuse to rollback a commit transaction if it isn't checked
out. Use --force to override this protection.
The rollback command can be entirely disabled by setting the ui.rollback configuration setting to false.
If you're here because you want to use rollback and it's disabled, you can re-enable the command by
setting ui.rollback to true.
This command is not intended for use on public repositories. Once changes are visible for pull by other
users, rolling a transaction back locally is ineffective (someone else may already have pulled the
changes). Furthermore, a race is possible with readers of the repository; for example an in-progress pull
from the repository may fail if a rollback is performed.
Returns 0 on success, 1 if no rollback data is available.
Options:
-n, --dry-run
do not perform actions, just print output
-f, --force
ignore safety measures
verify
verify the integrity of the repository:
hg verify
Verify the integrity of the current repository.
This will perform an extensive check of the repository's integrity, validating the hashes and checksums
of each entry in the changelog, manifest, and tracked files, as well as the integrity of their crosslinks
and indices.
Please see https://mercurial-scm.org/wiki/RepositoryCorruption for more information about recovery from
corruption of the repository.
For an alternative UI with a lot more control over the verification process and better error reporting,
try hg help admin::verify.
Returns 0 on success, 1 if errors are encountered.
Options:
--full perform more checks (EXPERIMENTAL)

Uncategorized commands
admin::chainsaw-update
pull and update to a given revision, no matter what, (EXPERIMENTAL):
hg admin::chainsaw-update [OPTION] --rev REV --source SOURCE --dest DEST
Context of application: some Continuous Integration (CI) systems, packaging or deployment tools.
Wanted end result: local repository at the given REPO_PATH, having the latest changes to the given
revision and with a clean working directory updated at the given revision.
chainsaw-update pulls from one source, then updates the working directory to the given revision,
overcoming anything that would stand in the way.
By default, it will:
• clone if the local repo does not exist yet, removing any directory at the given path that would not be
a Mercurial repository. The initial clone is full by default, so that clonebundles can be applied. Use
the --initial-clone-minimal flag to avoid this.
• break locks if needed, leading to possible corruption if there is a concurrent write access.
• perform recovery actions if needed
• revert any local modification.
• purge unknown and ignored files.
• go as far as to reclone if everything else failed (not implemented yet).
DO NOT use it for anything else than performing a series of unattended updates, with full exclusive
repository access each time and without any other local work than running build scripts. In case the
local repository is a share (see hg help share), exclusive write access to the share source is also
mandatory.
It is recommended to run these commands with the HGPLAIN environment variable (see hg scripting).
Motivation: in Continuous Integration and Delivery systems (CI/CD), the occasional remnant or bogus lock
are common sources of waste of time (both working time and calendar time). CI/CD scripts tend to grow
with counter- measures, often done in urgency. Also, whilst it is neat to keep repositories from one job
to the next (especially with large repositories), an exceptional recloning is better than missing a
release deadline.
Options:
--purge-unknown
Remove unversioned files before update. Disabling this can in some cases interfere with the
update.See also hg purge. (default: True)
--purge-ignored
Remove ignored files before update. Disable this for instance to reuse previous compiler object
files. See also hg purge. (default: True)
--rev <VALUE>
revision to update to
--source <VALUE>
repository to clone from
--dest <VALUE>
repository to update to REV (possibly cloning)
--initial-clone-minimal
Pull only the prescribed revision upon initial cloning. This has the side effect of ignoring
clone-bundles, which if often slower on the client side and stressful to the server than applying
available clone bundles.
BUNDLE FILE FORMATS
Mercurial supports generating standalone "bundle" files that hold repository data. These "bundles" are
typically saved locally and used later or exchanged between different repositories, possibly on different
machines. Example commands using bundles are hg bundle and hg unbundle.
Generation of bundle files is controlled by a "bundle specification" ("bundlespec") string. This string
tells the bundle generation process how to create the bundle.
A "bundlespec" string is composed of the following elements:
type A string denoting the bundle format to use.
compression
Denotes the compression engine to use compressing the raw bundle data.
parameters
Arbitrary key-value parameters to further control bundle generation.
A "bundlespec" string has the following formats:
<type> The literal bundle format string is used.
<compression>-<type>
The compression engine and format are delimited by a hyphen (-).
Optional parameters follow the <type>. Parameters are URI escaped key=value pairs. Each pair is delimited
by a semicolon (;). The first parameter begins after a ; immediately following the <type> value.
Available Types
The following bundle <type> strings are available:
v1 Produces a legacy "changegroup" version 1 bundle.
This format is compatible with nearly all Mercurial clients because it is the oldest. However, it
has some limitations, which is why it is no longer the default for new repositories.
v1 bundles can be used with modern repositories using the "generaldelta" storage format. However,
it may take longer to produce the bundle and the resulting bundle may be significantly larger than
a v2 bundle.
v1 bundles can only use the gzip, bzip2, and none compression formats.
v2 Produces a version 2 bundle.
Version 2 bundles are an extensible format that can store additional repository data (such as
bookmarks and phases information) and they can store data more efficiently, resulting in smaller
bundles.
Version 2 bundles can also use modern compression engines, such as zstd, making them faster to
compress and often smaller.
Available Compression Engines
The following bundle <compression> engines can be used:
bzip2
An algorithm that produces smaller bundles than gzip.
All Mercurial clients should support this format.
This engine will likely produce smaller bundles than gzip but will be significantly slower, both
during compression and decompression.
If available, the zstd engine can yield similar or better compression at much higher speeds.
gzip
zlib compression using the DEFLATE algorithm.
All Mercurial clients should support this format. The compression algorithm strikes a reasonable
balance between compression ratio and size.
none
No compression is performed.
Use this compression engine to explicitly disable compression.
The compression engines can be prepended with stream to create a streaming bundle. These are bundles
that are extremely efficient to produce and consume, but do not have guaranteed compatibility with older
clients.
Available Options
The following options exist:
changegroup
Include the changegroup data in the bundle (default to True).
cg.version
Select the version of the changegroup to use. Available options are : 01, 02 or 03. By default it
will be automatically selected according to the current repository format.
obsolescence
Include obsolescence-markers relevant to the bundled changesets.
phases Include phase information relevant to the bundled changesets.
revbranchcache
Include the "tags-fnodes" cache inside the bundle.
tagsfnodescache
Include the "tags-fnodes" cache inside the bundle.
Examples
v2
Produce a v2 bundle using default options, including compression.
none-v1
Produce a v1 bundle with no compression.
zstd-v2
Produce a v2 bundle with zstandard compression using default settings.
zstd-v1
This errors because zstd is not supported for v1 types.
none-streamv2
Produce a v2 streaming bundle with no compression.
zstd-v2;obsolescence=true;phases=true
Produce a v2 bundle with zstandard compression which includes obsolescence markers and phases.
COLORIZING OUTPUTS
Mercurial colorizes output from several commands.
For example, the diff command shows additions in green and deletions in red, while the status command
shows modified files in magenta. Many other commands have analogous colors. It is possible to customize
these colors.
To enable color (default) whenever possible use:
[ui]
color = yes
To disable color use:
[ui]
color = no
See hg help config.ui.color for details.
The default pager on Windows does not support color, so enabling the pager will effectively disable
color. See hg help config.ui.paginate to disable the pager. Alternately, MSYS and Cygwin shells provide
less as a pager, which can be configured to support ANSI color mode. Windows 10 natively supports ANSI
color mode.
Mode
Mercurial can use various systems to display color. The supported modes are ansi, win32, and terminfo.
See hg help config.color for details about how to control the mode.
Effects
Other effects in addition to color, like bold and underlined text, are also available. By default, the
terminfo database is used to find the terminal codes used to change color and effect. If terminfo is not
available, then effects are rendered with the ECMA-48 SGR control function (aka ANSI escape codes).
The available effects in terminfo mode are 'blink', 'bold', 'dim', 'inverse', 'invisible', 'italic',
'standout', and 'underline'; in ECMA-48 mode, the options are 'bold', 'inverse', 'italic', and
'underline'. How each is rendered depends on the terminal emulator. Some may not be available for a
given terminal type, and will be silently ignored.
If the terminfo entry for your terminal is missing codes for an effect or has the wrong codes, you can
add or override those codes in your configuration:
[color]
terminfo.dim = \E[2m
where 'E' is substituted with an escape character.
Labels
Text receives color effects depending on the labels that it has. Many default Mercurial commands emit
labelled text. You can also define your own labels in templates using the label function, see hg help
templates. In order to receive effects, labels must have a dot, such as log.secret or branch.active. A
single portion of text may have more than one label. In that case, effects given to the last label will
override any other effects. This includes the special "none" effect, which nullifies other effects.
Labels are normally invisible. In order to see these labels and their position in the text, use the
global --color=debug option. The same anchor text may be associated to multiple labels, e.g.
[log.changeset changeset.secret|changeset: 22611:6f0a53c8f587]
The following are the default effects for some default labels. Default effects may be overridden from
your configuration file:
[color]
status.modified = blue bold underline red_background
status.added = green bold
status.removed = red bold blue_background
status.deleted = cyan bold underline
status.unknown = magenta bold underline
status.ignored = black bold
# 'none' turns off all effects
status.clean = none
status.copied = none
qseries.applied = blue bold underline
qseries.unapplied = black bold
qseries.missing = red bold
diff.diffline = bold
diff.extended = cyan bold
diff.file_a = red bold
diff.file_b = green bold
diff.hunk = magenta
diff.deleted = red
diff.inserted = green
diff.changed = white
diff.tab =
diff.trailingwhitespace = bold red_background
# Blank so it inherits the style of the surrounding label
changeset.public =
changeset.draft =
changeset.secret =
resolve.unresolved = red bold
resolve.resolved = green bold
bookmarks.active = green
branches.active = none
branches.closed = black bold
branches.current = green
branches.inactive = none
tags.normal = green
tags.local = black bold
rebase.rebased = blue
rebase.remaining = red bold
shelve.age = cyan
shelve.newest = green bold
shelve.name = blue bold
histedit.remaining = red bold
Custom colors
Because there are only eight standard colors, Mercurial allows you to define color names for other color
slots which might be available for your terminal type, assuming terminfo mode. For instance:
color.brightblue = 12
color.pink = 207
color.orange = 202
to set 'brightblue' to color slot 12 (useful for 16 color terminals that have brighter colors defined in
the upper eight) and, 'pink' and 'orange' to colors in 256-color xterm's default color cube. These
defined colors may then be used as any of the pre-defined eight, including appending '_background' to set
the background to that color.
DATE FORMATS
Some commands allow the user to specify a date, e.g.:
• backout, commit, import, tag: Specify the commit date.
• log, revert, update: Select revision(s) by date.
Many date formats are valid. Here are some examples:
• Wed Dec 6 13:18:29 2006 (local timezone assumed)
• Dec 6 13:18 -0600 (year assumed, time offset provided)
• Dec 6 13:18 UTC (UTC and GMT are aliases for +0000)
• Dec 6 (midnight)
• 13:18 (today assumed)
• 3:39 (3:39AM assumed)
• 3:39pm (15:39)
• 2006-12-06 13:18:29 (ISO 8601 format)
• 2006-12-6 13:18
• 2006-12-6
• 12-6
• 12/6
• 12/6/6 (Dec 6 2006)
• today (midnight)
• yesterday (midnight)
• now - right now
Lastly, there is Mercurial's internal format:
• 1165411109 0 (Wed Dec 6 13:18:29 2006 UTC)
This is the internal representation format for dates. The first number is the number of seconds since the
epoch (1970-01-01 00:00 UTC). The second is the offset of the local timezone, in seconds west of UTC
(negative if the timezone is east of UTC).
The log command also accepts date ranges:
• <DATE - at or before a given date/time
• >DATE - on or after a given date/time
• DATE to DATE - a date range, inclusive
• -DAYS - within a given number of days from today
DEPRECATED FEATURES
Mercurial evolves over time, some features, options, commands may be replaced by better and more secure
alternatives. This topic will help you migrating your existing usage and/or configuration to newer
features.
Commands
The following commands are still available but their use are not recommended:
locate
This command has been replaced by hg files.
parents
This command can be replaced by hg summary or hg log with appropriate revsets. See hg help revsets for
more information.
tip
The recommended alternative is hg heads.
Options
web.allowpull
Renamed to allow-pull.
web.allow_push
Renamed to allow-push.
DIFF FORMATS
Mercurial's default format for showing changes between two versions of a file is compatible with the
unified format of GNU diff, which can be used by GNU patch and many other standard tools.
While this standard format is often enough, it does not encode the following information:
• executable status and other permission bits
• copy or rename information
• changes in binary files
• creation or deletion of empty files
Mercurial also supports the extended diff format from the git VCS which addresses these limitations. The
git diff format is not produced by default because a few widespread tools still do not understand this
format.
This means that when generating diffs from a Mercurial repository (e.g. with hg export), you should be
careful about things like file copies and renames or other things mentioned above, because when applying
a standard diff to a different repository, this extra information is lost. Mercurial's internal
operations (like push and pull) are not affected by this, because they use an internal binary format for
communicating changes.
To make Mercurial produce the git extended diff format, use the --git option available for many commands,
or set 'git = True' in the [diff] section of your configuration file. You do not need to set this option
when importing diffs in this format or using them in the mq extension.
ENVIRONMENT VARIABLES
HG Path to the 'hg' executable, automatically passed when running hooks, extensions or external
tools. If unset or empty, this is the hg executable's name if it's frozen, or an executable named
'hg' (with %PATHEXT% [defaulting to COM/EXE/BAT/CMD] extensions on Windows) is searched.
HGEDITOR
This is the name of the editor to run when committing. See EDITOR.
(deprecated, see hg help config.ui.editor)
HGENCODING
This overrides the default locale setting detected by Mercurial. This setting is used to convert
data including usernames, changeset descriptions, tag names, and branches. This setting can be
overridden with the --encoding command-line option.
HGENCODINGMODE
This sets Mercurial's behavior for handling unknown characters while transcoding user input. The
default is "strict", which causes Mercurial to abort if it can't map a character. Other settings
include "replace", which replaces unknown characters, and "ignore", which drops them. This setting
can be overridden with the --encodingmode command-line option.
HGENCODINGAMBIGUOUS
This sets Mercurial's behavior for handling characters with "ambiguous" widths like accented Latin
characters with East Asian fonts. By default, Mercurial assumes ambiguous characters are narrow,
set this variable to "wide" if such characters cause formatting problems.
HGMERGE
An executable to use for resolving merge conflicts. The program will be executed with three
arguments: local file, remote file, ancestor file.
(deprecated, see hg help config.ui.merge)
HGRCPATH
A list of files or directories to search for configuration files. Item separator is ":" on Unix,
";" on Windows. If HGRCPATH is not set, platform default search path is used. If empty, only the
.hg/hgrc from the current repository is read.
For each element in HGRCPATH:
• if it's a directory, all files ending with .rc are added
• otherwise, the file itself will be added
HGRCSKIPREPO
When set, the .hg/hgrc from repositories are not read.
HGPLAIN
When set, this disables any configuration settings that might change Mercurial's default output.
This includes encoding, defaults, verbose mode, debug mode, quiet mode, tracebacks, and
localization. This can be useful when scripting against Mercurial in the face of existing user
configuration.
In addition to the features disabled by HGPLAIN=, the following values can be specified to adjust
behavior:
+strictflags
Restrict parsing of command line flags.
Equivalent options set via command line flags or environment variables are not overridden.
See hg help scripting for details.
HGPLAINEXCEPT
This is a comma-separated list of features to preserve when HGPLAIN is enabled. Currently the
following values are supported:
alias
Don't remove aliases.
color
Don't disable colored output.
i18n
Preserve internationalization.
revsetalias
Don't remove revset aliases.
templatealias
Don't remove template aliases.
progress
Don't hide progress output.
Setting HGPLAINEXCEPT to anything (even an empty string) will enable plain mode.
HGUSER This is the string used as the author of a commit. If not set, available values will be considered
in this order:
• HGUSER (deprecated)
• configuration files from the HGRCPATH
• EMAIL
• interactive prompt
• LOGNAME (with @hostname appended)
(deprecated, see hg help config.ui.username)
EMAIL May be used as the author of a commit; see HGUSER.
LOGNAME
May be used as the author of a commit; see HGUSER.
VISUAL This is the name of the editor to use when committing. See EDITOR.
EDITOR Sometimes Mercurial needs to open a text file in an editor for a user to modify, for example when
writing commit messages. The editor it uses is determined by looking at the environment variables
HGEDITOR, VISUAL and EDITOR, in that order. The first non-empty one is chosen. If all of them are
empty, the editor defaults to 'vi'.
PYTHONPATH
This is used by Python to find imported modules and may need to be set appropriately if this
Mercurial is not installed system-wide.
SAFELY REWRITING HISTORY (EXPERIMENTAL)
Obsolescence markers make it possible to mark changesets that have been deleted or superseded in a new
version of the changeset.
Unlike the previous way of handling such changes, by stripping the old changesets from the repository,
obsolescence markers can be propagated between repositories. This allows for a safe and simple way of
exchanging mutable history and altering it after the fact. Changeset phases are respected, such that only
draft and secret changesets can be altered (see hg help phases for details).
Obsolescence is tracked using "obsolescence markers", a piece of metadata tracking which changesets have
been made obsolete, potential successors for a given changeset, the moment the changeset was marked as
obsolete, and the user who performed the rewriting operation. The markers are stored separately from
standard changeset data can be exchanged without any of the precursor changesets, preventing unnecessary
exchange of obsolescence data.
The complete set of obsolescence markers describes a history of changeset modifications that is
orthogonal to the repository history of file modifications. This changeset history allows for detection
and automatic resolution of edge cases arising from multiple users rewriting the same part of history
concurrently.
Current feature status
This feature is still in development.
Instability
Rewriting changesets might introduce instability.
There are two main kinds of instability: orphaning and diverging.
Orphans are changesets left behind when their ancestors are rewritten. Divergence has two variants:
• Content-divergence occurs when independent rewrites of the same changesets lead to different results.
• Phase-divergence occurs when the old (obsolete) version of a changeset becomes public.
It is possible to prevent local creation of orphans by using the following config:
[experimental]
evolution.createmarkers = true
evolution.exchange = true
You can also enable that option explicitly:
[experimental]
evolution.createmarkers = true
evolution.exchange = true
evolution.allowunstable = true
USING ADDITIONAL FEATURES
Mercurial has the ability to add new features through the use of extensions. Extensions may add new
commands, add options to existing commands, change the default behavior of commands, or implement hooks.
To enable the "foo" extension, either shipped with Mercurial or in the Python search path, create an
entry for it in your configuration file, like this:
[extensions]
foo =
You may also specify the full path to an extension:
[extensions]
myfeature = ~/.hgext/myfeature.py
See hg help config for more information on configuration files.
Extensions are not loaded by default for a variety of reasons: they can increase startup overhead; they
may be meant for advanced usage only; they may provide potentially dangerous abilities (such as letting
you destroy or modify history); they might not be ready for prime time; or they may alter some usual
behaviors of stock Mercurial. It is thus up to the user to activate extensions as needed.
To explicitly disable an extension enabled in a configuration file of broader scope, prepend its path
with !:
[extensions]
# disabling extension bar residing in /path/to/extension/bar.py
bar = !/path/to/extension/bar.py
# ditto, but no path was supplied for extension baz
baz = !
disabled extensions:
acl hooks for controlling repository access

SPECIFYING FILE SETS
Mercurial supports a functional language for selecting a set of files.
Like other file patterns, this pattern type is indicated by a prefix, 'set:'. The language supports a
number of predicates which are joined by infix operators. Parenthesis can be used for grouping.
Identifiers such as filenames or patterns must be quoted with single or double quotes if they contain
characters outside of [.*{}[]?/\_a-zA-Z0-9\x80-\xff] or if they match one of the predefined predicates.
This generally applies to file patterns other than globs and arguments for predicates. Pattern prefixes
such as path: may be specified without quoting.
Special characters can be used in quoted identifiers by escaping them, e.g., \n is interpreted as a
newline. To prevent them from being interpreted, strings can be prefixed with r, e.g. r'...'.
See also hg help patterns.
Operators
There is a single prefix operator:
not x
Files not in x. Short form is ! x.
These are the supported infix operators:
x and y
The intersection of files in x and y. Short form is x & y.
x or y
The union of files in x and y. There are two alternative short forms: x | y and x + y.
x - y
Files in x but not in y.
Predicates
The following predicates are supported:
added()
File that is added according to hg status.
binary()
File that appears to be binary (contains NUL bytes).
clean()
File that is clean according to hg status.
copied()
File that is recorded as being copied.
deleted()
Alias for missing().
encoding(name)
File can be successfully decoded with the given character encoding. May not be useful for
encodings other than ASCII and UTF-8.
eol(style)
File contains newlines of the given style (dos, unix, mac). Binary files are excluded, files with
mixed line endings match multiple styles.
exec()
File that is marked as executable.
grep(regex)
File contains the given regular expression.
hgignore()
File that matches the active .hgignore pattern.
ignored()
File that is ignored according to hg status.
missing()
File that is missing according to hg status.
modified()
File that is modified according to hg status.
portable()
File that has a portable name. (This doesn't include filenames with case collisions.)
removed()
File that is removed according to hg status.
resolved()
File that is marked resolved according to hg resolve -l.
revs(revs, pattern)
Evaluate set in the specified revisions. If the revset match multiple revs, this will return file
matching pattern in any of the revision.
size(expression)
File size matches the given expression. Examples:
• size('1k') - files from 1024 to 2047 bytes
• size('< 20k') - files less than 20480 bytes
• size('>= .5MB') - files at least 524288 bytes
• size('4k - 1MB') - files from 4096 bytes to 1048576 bytes
status(base, rev, pattern)
Evaluate predicate using status change between base and rev. Examples:
• status(3, 7, added()) - matches files added from "3" to "7"
subrepo([pattern])
Subrepositories whose paths match the given pattern.
symlink()
File that is marked as a symlink.
tracked()
File that is under Mercurial control.
unknown()
File that is unknown according to hg status.
unresolved()
File that is marked unresolved according to hg resolve -l.
Examples
Some sample queries:
• Show status of files that appear to be binary in the working directory:
hg status -A "set:binary()"
• Forget files that are in .hgignore but are already tracked:
hg forget "set:hgignore() and not ignored()"
• Find text files that contain a string:
hg files "set:grep(magic) and not binary()"
• Find C files in a non-standard encoding:
hg files "set:**.c and not encoding('UTF-8')"
• Revert copies of large binary files:
hg revert "set:copied() and binary() and size('>1M')"
• Revert files that were added to the working directory:
hg revert "set:revs('wdir()', added())"
• Remove files listed in foo.lst that contain the letter a or b:
hg remove "set: listfile:foo.lst and (**a* or **b*)"
COMMAND-LINE FLAGS
Most Mercurial commands accept various flags.
Flag names
Flags for each command are listed in hg help for that command. Additionally, some flags, such as
--repository, are global and can be used with any command - those are seen in hg help -v, and can be
specified before or after the command.
Every flag has at least a long name, such as --repository. Some flags may also have a short one-letter
name, such as the equivalent -R. Using the short or long name is equivalent and has the same effect. The
long name may be abbreviated to any unambiguous prefix. For example, hg commit --amend can be abbreviated
to hg commit --am.
Flags that have a short name can also be bundled together - for instance, to specify both --edit (short
-e) and --interactive (short -i), one could use:
hg commit -ei
If any of the bundled flags takes a value (i.e. is not a boolean), it must be last, followed by the
value:
hg commit -im 'Message'
Flag types
Mercurial command-line flags can be strings, numbers, booleans, or lists of strings.
Specifying flag values
The following syntaxes are allowed, assuming a flag 'flagname' with short name 'f':
--flagname=foo
--flagname foo
-f foo
-ffoo
This syntax applies to all non-boolean flags (strings, numbers or lists).
Specifying boolean flags
Boolean flags do not take a value parameter. To specify a boolean, use the flag name to set it to true,
or the same name prefixed with 'no-' to set it to false:
hg commit --interactive
hg commit --no-interactive
Specifying list flags
List flags take multiple values. To specify them, pass the flag multiple times:
hg files --include mercurial --include tests
Setting flag defaults
In order to set a default value for a flag in an hgrc file, it is recommended to use aliases:
[alias]
commit = commit --interactive
For more information on hgrc files, see hg help config.
Overriding flags on the command line
If the same non-list flag is specified multiple times on the command line, the latest specification is
used:
hg commit -m "Ignored value" -m "Used value"
This includes the use of aliases - e.g., if one has:
[alias]
committemp = commit -m "Ignored value"
then the following command will override that -m:
hg committemp -m "Used value"
Overriding flag defaults
Every flag has a default value, and you may also set your own defaults in hgrc as described above.
Except for list flags, defaults can be overridden on the command line simply by specifying the flag in
that location.
Hidden flags
Some flags are not shown in a command's help by default - specifically, those that are deemed to be
experimental, deprecated or advanced. To show all flags, add the --verbose flag for the help command:
hg help --verbose commit
GLOSSARY
Ancestor
Any changeset that can be reached by an unbroken chain of parent changesets from a given
changeset. More precisely, the ancestors of a changeset can be defined by two properties: a parent
of a changeset is an ancestor, and a parent of an ancestor is an ancestor. See also: 'Descendant'.
Bookmark
Bookmarks are pointers to certain commits that move when committing. They are similar to tags in
that it is possible to use bookmark names in all places where Mercurial expects a changeset ID,
e.g., with hg update. Unlike tags, bookmarks move along when you make a commit.
Bookmarks can be renamed, copied and deleted. Bookmarks are local, unless they are explicitly
pushed or pulled between repositories. Pushing and pulling bookmarks allow you to collaborate
with others on a branch without creating a named branch.
Branch (Noun) A child changeset that has been created from a parent that is not a head. These are known
as topological branches, see 'Branch, topological'. If a topological branch is named, it becomes a
named branch. If a topological branch is not named, it becomes an anonymous branch. See 'Branch,
anonymous' and 'Branch, named'.
Branches may be created when changes are pulled from or pushed to a remote repository, since new
heads may be created by these operations. Note that the term branch can also be used informally to
describe a development process in which certain development is done independently of other
development. This is sometimes done explicitly with a named branch, but it can also be done
locally, using bookmarks or clones and anonymous branches.
Example: "The experimental branch."
(Verb) The action of creating a child changeset which results in its parent having more than one
child.
Example: "I'm going to branch at X."
Branch, anonymous
Every time a new child changeset is created from a parent that is not a head and the name of the
branch is not changed, a new anonymous branch is created.
Branch, closed
A named branch whose branch heads have all been closed.
Branch, default
The branch assigned to a changeset when no name has previously been assigned.
Branch head
See 'Head, branch'.
Branch, inactive
If a named branch has no topological heads, it is considered to be inactive. As an example, a
feature branch becomes inactive when it is merged into the default branch. The hg branches command
shows inactive branches by default, though they can be hidden with hg branches --active.
NOTE: this concept is deprecated because it is too implicit. Branches should now be explicitly
closed using hg commit --close-branch when they are no longer needed.
Branch, named
A collection of changesets which have the same branch name. By default, children of a changeset in
a named branch belong to the same named branch. A child can be explicitly assigned to a different
branch. See hg help branch, hg help branches and hg commit --close-branch for more information on
managing branches.
Named branches can be thought of as a kind of namespace, dividing the collection of changesets
that comprise the repository into a collection of disjoint subsets. A named branch is not
necessarily a topological branch. If a new named branch is created from the head of another named
branch, or the default branch, but no further changesets are added to that previous branch, then
that previous branch will be a branch in name only.
Branch tip
See 'Tip, branch'.
Branch, topological
Every time a new child changeset is created from a parent that is not a head, a new topological
branch is created. If a topological branch is named, it becomes a named branch. If a topological
branch is not named, it becomes an anonymous branch of the current, possibly default, branch.
Changelog
A record of the changesets in the order in which they were added to the repository. This includes
details such as changeset id, author, commit message, date, and list of changed files.
Changeset
A snapshot of the state of the repository used to record a change.
Changeset, child
The converse of parent changeset: if P is a parent of C, then C is a child of P. There is no limit
to the number of children that a changeset may have.
Changeset id
A SHA-1 hash that uniquely identifies a changeset. It may be represented as either a "long" 40
hexadecimal digit string, or a "short" 12 hexadecimal digit string.
Changeset, merge
A changeset with two parents. This occurs when a merge is committed.
Changeset, parent
A revision upon which a child changeset is based. Specifically, a parent changeset of a changeset
C is a changeset whose node immediately precedes C in the DAG. Changesets have at most two
parents.
Checkout
(Noun) The working directory being updated to a specific revision. This use should probably be
avoided where possible, as changeset is much more appropriate than checkout in this context.
Example: "I'm using checkout X."
(Verb) Updating the working directory to a specific changeset. See hg help update.
Example: "I'm going to check out changeset X."
Child changeset
See 'Changeset, child'.
Close changeset
See 'Head, closed branch'.
Closed branch
See 'Branch, closed'.
Clone (Noun) An entire or partial copy of a repository. The partial clone must be in the form of a
revision and its ancestors.
Example: "Is your clone up to date?"
(Verb) The process of creating a clone, using hg clone.
Example: "I'm going to clone the repository."
Closed branch head
See 'Head, closed branch'.
Commit (Noun) A synonym for changeset.
Example: "Is the bug fixed in your recent commit?"
(Verb) The act of recording changes to a repository. When files are committed in a working
directory, Mercurial finds the differences between the committed files and their parent changeset,
creating a new changeset in the repository.
Example: "You should commit those changes now."
Cset A common abbreviation of the term changeset.
DAG The repository of changesets of a distributed version control system (DVCS) can be described as a
directed acyclic graph (DAG), consisting of nodes and edges, where nodes correspond to changesets
and edges imply a parent -> child relation. This graph can be visualized by graphical tools such
as hg log --graph. In Mercurial, the DAG is limited by the requirement for children to have at
most two parents.
Deprecated
Feature removed from documentation, but not scheduled for removal.
Default branch
See 'Branch, default'.
Descendant
Any changeset that can be reached by a chain of child changesets from a given changeset. More
precisely, the descendants of a changeset can be defined by two properties: the child of a
changeset is a descendant, and the child of a descendant is a descendant. See also: 'Ancestor'.
Diff (Noun) The difference between the contents and attributes of files in two changesets or a
changeset and the current working directory. The difference is usually represented in a standard
form called a "diff" or "patch". The "git diff" format is used when the changes include copies,
renames, or changes to file attributes, none of which can be represented/handled by classic "diff"
and "patch".
Example: "Did you see my correction in the diff?"
(Verb) Diffing two changesets is the action of creating a diff or patch.
Example: "If you diff with changeset X, you will see what I mean."
Directory, working
The working directory represents the state of the files tracked by Mercurial, that will be
recorded in the next commit. The working directory initially corresponds to the snapshot at an
existing changeset, known as the parent of the working directory. See 'Parent, working directory'.
The state may be modified by changes to the files introduced manually or by a merge. The
repository metadata exists in the .hg directory inside the working directory.
Draft Changesets in the draft phase have not been shared with publishing repositories and may thus be
safely changed by history-modifying extensions. See hg help phases.
Experimental
Feature that may change or be removed at a later date.
Graph See DAG and hg log --graph.
Head The term 'head' may be used to refer to both a branch head or a repository head, depending on the
context. See 'Head, branch' and 'Head, repository' for specific definitions.
Heads are where development generally takes place and are the usual targets for update and merge
operations.
Head, branch
A changeset with no descendants on the same named branch.
Head, closed branch
A changeset that marks a head as no longer interesting. The closed head is no longer listed by hg
heads. A branch is considered closed when all its heads are closed and consequently is not listed
by hg branches.
Closed heads can be re-opened by committing new changeset as the child of the changeset that marks
a head as closed.
Head, repository
A topological head which has not been closed.
Head, topological
A changeset with no children in the repository.
History, immutable
Once committed, changesets cannot be altered. Extensions which appear to change history actually
create new changesets that replace existing ones, and then destroy the old changesets. Doing so in
public repositories can result in old changesets being reintroduced to the repository.
History, rewriting
The changesets in a repository are immutable. However, extensions to Mercurial can be used to
alter the repository, usually in such a way as to preserve changeset contents.
Immutable history
See 'History, immutable'.
Merge changeset
See 'Changeset, merge'.
Manifest
Each changeset has a manifest, which is the list of files that are tracked by the changeset.
Merge Used to bring together divergent branches of work. When you update to a changeset and then merge
another changeset, you bring the history of the latter changeset into your working directory. Once
conflicts are resolved (and marked), this merge may be committed as a merge changeset, bringing
two branches together in the DAG.
Named branch
See 'Branch, named'.
Null changeset
The empty changeset. It is the parent state of newly-initialized repositories and repositories
with no checked out revision. It is thus the parent of root changesets and the effective ancestor
when merging unrelated changesets. Can be specified by the alias 'null' or by the changeset ID
'000000000000'.
Parent See 'Changeset, parent'.
Parent changeset
See 'Changeset, parent'.
Parent, working directory
The working directory parent reflects a virtual revision which is the child of the changeset (or
two changesets with an uncommitted merge) shown by hg parents. This is changed with hg update.
Other commands to see the working directory parent are hg summary and hg id. Can be specified by
the alias ".".
Patch (Noun) The product of a diff operation.
Example: "I've sent you my patch."
(Verb) The process of using a patch file to transform one changeset into another.
Example: "You will need to patch that revision."
Phase A per-changeset state tracking how the changeset has been or should be shared. See hg help phases.
Public Changesets in the public phase have been shared with publishing repositories and are therefore
considered immutable. See hg help phases.
Pull An operation in which changesets in a remote repository which are not in the local repository are
brought into the local repository. Note that this operation without special arguments only updates
the repository, it does not update the files in the working directory. See hg help pull.
Push An operation in which changesets in a local repository which are not in a remote repository are
sent to the remote repository. Note that this operation only adds changesets which have been
committed locally to the remote repository. Uncommitted changes are not sent. See hg help push.
Repository
The metadata describing all recorded states of a collection of files. Each recorded state is
represented by a changeset. A repository is usually (but not always) found in the .hg subdirectory
of a working directory. Any recorded state can be recreated by "updating" a working directory to a
specific changeset.
Repository head
See 'Head, repository'.
Revision
A state of the repository at some point in time. Earlier revisions can be updated to by using hg
update. See also 'Revision number'; See also 'Changeset'.
Revision number
This integer uniquely identifies a changeset in a specific repository. It represents the order in
which changesets were added to a repository, starting with revision number 0. Note that the
revision number may be different in each clone of a repository. To identify changesets uniquely
between different clones, see 'Changeset id'.
Revlog History storage mechanism used by Mercurial. It is a form of delta encoding, with occasional full
revision of data followed by delta of each successive revision. It includes data and an index
pointing to the data.
Rewriting history
See 'History, rewriting'.
Root A changeset that has only the null changeset as its parent. Most repositories have only a single
root changeset.
Secret Changesets in the secret phase may not be shared via push, pull, or clone. See hg help phases.
Tag An alternative name given to a changeset. Tags can be used in all places where Mercurial expects a
changeset ID, e.g., with hg update. The creation of a tag is stored in the history and will thus
automatically be shared with other using push and pull.
Tip The changeset with the highest revision number. It is the changeset most recently added in a
repository.
Tip, branch
The head of a given branch with the highest revision number. When a branch name is used as a
revision identifier, it refers to the branch tip. See also 'Branch, head'. Note that because
revision numbers may be different in different repository clones, the branch tip may be different
in different cloned repositories.
Update (Noun) Another synonym of changeset.
Example: "I've pushed an update."
(Verb) This term is usually used to describe updating the state of the working directory to that
of a specific changeset. See hg help update.
Example: "You should update."
Working directory
See 'Directory, working'.
Working directory parent
See 'Parent, working directory'.
SYNTAX FOR MERCURIAL IGNORE FILES
Synopsis
The Mercurial system uses a file called .hgignore in the root directory of a repository to control its
behavior when it searches for files that it is not currently tracking.
Description
The working directory of a Mercurial repository will often contain files that should not be tracked by
Mercurial. These include backup files created by editors and build products created by compilers. These
files can be ignored by listing them in a .hgignore file in the root of the working directory. The
.hgignore file must be created manually. It is typically put under version control, so that the settings
will propagate to other repositories with push and pull.
An untracked file is ignored if its path relative to the repository root directory, or any prefix path of
that path, is matched against any pattern in .hgignore.
For example, say we have an untracked file, file.c, at a/b/file.c inside our repository. Mercurial will
ignore file.c if any pattern in .hgignore matches a/b/file.c, a/b or a.
In addition, a Mercurial configuration file can reference a set of per-user or global ignore files. See
the ignore configuration key on the [ui] section of hg help config for details of how to configure these
files.
To control Mercurial's handling of files that it manages, many commands support the -I and -X options;
see hg help <command> and hg help patterns for details.
Files that are already tracked are not affected by .hgignore, even if they appear in .hgignore. An
untracked file X can be explicitly added with hg add X, even if X would be excluded by a pattern in
.hgignore.
Syntax
An ignore file is a plain text file consisting of a list of patterns, with one pattern per line. Empty
lines are skipped. The # character is treated as a comment character, and the \ character is treated as
an escape character.
Mercurial supports several pattern syntaxes. The default syntax used is Python/Perl-style regular
expressions.
To change the syntax used, use a line of the following form:
syntax: NAME
where NAME is one of the following:
regexp
Regular expression, Python/Perl syntax.
glob
Shell-style glob.
rootglob
A variant of glob that is rooted (see below).
The chosen syntax stays in effect when parsing all patterns that follow, until another syntax is
selected.
Neither glob nor regexp patterns are rooted. A glob-syntax pattern of the form *.c will match a file
ending in .c in any directory, and a regexp pattern of the form \.c$ will do the same. To root a regexp
pattern, start it with ^. To get the same effect with glob-syntax, you have to use rootglob.
Subdirectories can have their own .hgignore settings by adding subinclude:path/to/subdir/.hgignore to the
root .hgignore. See hg help patterns for details on subinclude: and include:.
Note Patterns specified in other than .hgignore are always rooted. Please see hg help patterns for
details.
Example
Here is an example ignore file.
# use glob syntax.
syntax: glob
*.elc
*.pyc
*~
# switch to regexp syntax.
syntax: regexp
^\.pc/
Debugging
Use the debugignore command to see if and why a file is ignored, or to see the combined ignore pattern.
See hg help debugignore for details.
CONFIGURING HGWEB
Mercurial's internal web server, hgweb, can serve either a single repository, or a tree of repositories.
In the second case, repository paths and global options can be defined using a dedicated configuration
file common to hg serve, hgweb.wsgi, hgweb.cgi and hgweb.fcgi.
This file uses the same syntax as other Mercurial configuration files but recognizes only the following
sections:
• web
• paths
• collections
The web options are thoroughly described in hg help config.
The paths section maps URL paths to paths of repositories in the filesystem. hgweb will not expose the
filesystem directly - only Mercurial repositories can be published and only according to the
configuration.
The left hand side is the path in the URL. Note that hgweb reserves subpaths like rev or file, try using
different names for nested repositories to avoid confusing effects.
The right hand side is the path in the filesystem. If the specified path ends with * or ** the filesystem
will be searched recursively for repositories below that point. With * it will not recurse into the
repositories it finds (except for .hg/patches). With ** it will also search inside repository working
directories and possibly find subrepositories.
In this example:
[paths]
/projects/a = /srv/tmprepos/a
/projects/b = c:/repos/b
/ = /srv/repos/*
/user/bob = /home/bob/repos/**
• The first two entries make two repositories in different directories appear under the same directory in
the web interface
• The third entry will publish every Mercurial repository found in /srv/repos/, for instance the
repository /srv/repos/quux/ will appear as http://server/quux/
• The fourth entry will publish both http://server/user/bob/quux/ and
http://server/user/bob/quux/testsubrepo/
The collections section is deprecated and has been superseded by paths.
URLs and Common Arguments
URLs under each repository have the form /{command}[/{arguments}] where {command} represents the name of
a command or handler and {arguments} represents any number of additional URL parameters to that command.
The web server has a default style associated with it. Styles map to a collection of named templates.
Each template is used to render a specific piece of data, such as a changeset or diff.
The style for the current request can be overridden two ways. First, if {command} contains a hyphen (-),
the text before the hyphen defines the style. For example, /atom-log will render the log command handler
with the atom style. The second way to set the style is with the style query string argument. For
example, /log?style=atom. The hyphenated URL parameter is preferred.
Not all templates are available for all styles. Attempting to use a style that doesn't have all templates
defined may result in an error rendering the page.
Many commands take a {revision} URL parameter. This defines the changeset to operate on. This is commonly
specified as the short, 12 digit hexadecimal abbreviation for the full 40 character unique revision
identifier. However, any value described by hg help revisions typically works.
Commands and URLs
The following web commands and their URLs are available:
/annotate/{revision}/{path}
Show changeset information for each line in a file.
The ignorews, ignorewsamount, ignorewseol, and ignoreblanklines query string arguments have the same
meaning as their [annotate] config equivalents. It uses the hgrc boolean parsing logic to interpret the
value. e.g. 0 and false are false and 1 and true are true. If not defined, the server default settings
are used.
The fileannotate template is rendered.
/archive/{revision}.{format}[/{path}]
Obtain an archive of repository content.
The content and type of the archive is defined by a URL path parameter. format is the file extension of
the archive type to be generated. e.g. zip or tar.bz2. Not all archive types may be allowed by your
server configuration.
The optional path URL parameter controls content to include in the archive. If omitted, every file in the
specified revision is present in the archive. If included, only the specified file or contents of the
specified directory will be included in the archive.
No template is used for this handler. Raw, binary content is generated.
/bookmarks
Show information about bookmarks.
No arguments are accepted.
The bookmarks template is rendered.
/branches
Show information about branches.
All known branches are contained in the output, even closed branches.
No arguments are accepted.
The branches template is rendered.
/changelog[/{revision}]
Show information about multiple changesets.
If the optional revision URL argument is absent, information about all changesets starting at tip will be
rendered. If the revision argument is present, changesets will be shown starting from the specified
revision.
If revision is absent, the rev query string argument may be defined. This will perform a search for
changesets.
The argument for rev can be a single revision, a revision set, or a literal keyword to search for in
changeset data (equivalent to hg log -k).
The revcount query string argument defines the maximum numbers of changesets to render.
For non-searches, the changelog template will be rendered.
/changeset[/{revision}]
Show information about a single changeset.
A URL path argument is the changeset identifier to show. See hg help revisions for possible values. If
not defined, the tip changeset will be shown.
The changeset template is rendered. Contents of the changesettag, changesetbookmark, filenodelink,
filenolink, and the many templates related to diffs may all be used to produce the output.
/comparison/{revision}/{path}
Show a comparison between the old and new versions of a file from changes made on a particular revision.
This is similar to the diff handler. However, this form features a split or side-by-side diff rather than
a unified diff.
The context query string argument can be used to control the lines of context in the diff.
The filecomparison template is rendered.
/diff/{revision}/{path}
Show how a file changed in a particular commit.
The filediff template is rendered.
This handler is registered under both the /diff and /filediff paths. /diff is used in modern code.
/file/{revision}[/{path}]
Show information about a directory or file in the repository.
Info about the path given as a URL parameter will be rendered.
If path is a directory, information about the entries in that directory will be rendered. This form is
equivalent to the manifest handler.
If path is a file, information about that file will be shown via the filerevision template.
If path is not defined, information about the root directory will be rendered.
/diff/{revision}/{path}
Show how a file changed in a particular commit.
The filediff template is rendered.
This handler is registered under both the /diff and /filediff paths. /diff is used in modern code.
/filelog/{revision}/{path}
Show information about the history of a file in the repository.
The revcount query string argument can be defined to control the maximum number of entries to show.
The filelog template will be rendered.
/graph[/{revision}]
Show information about the graphical topology of the repository.
Information rendered by this handler can be used to create visual representations of repository topology.
The revision URL parameter controls the starting changeset. If it's absent, the default is tip.
The revcount query string argument can define the number of changesets to show information for.
The graphtop query string argument can specify the starting changeset for producing jsdata variable that
is used for rendering graph in JavaScript. By default it has the same value as revision.
This handler will render the graph template.
/help[/{topic}]
Render help documentation.
This web command is roughly equivalent to hg help. If a topic is defined, that help topic will be
rendered. If not, an index of available help topics will be rendered.
The help template will be rendered when requesting help for a topic. helptopics will be rendered for the
index of help topics.
/log[/{revision}[/{path}]]
Show repository or file history.
For URLs of the form /log/{revision}, a list of changesets starting at the specified changeset identifier
is shown. If {revision} is not defined, the default is tip. This form is equivalent to the changelog
handler.
For URLs of the form /log/{revision}/{file}, the history for a specific file will be shown. This form is
equivalent to the filelog handler.
/manifest[/{revision}[/{path}]]
Show information about a directory.
If the URL path arguments are omitted, information about the root directory for the tip changeset will be
shown.
Because this handler can only show information for directories, it is recommended to use the file handler
instead, as it can handle both directories and files.
The manifest template will be rendered for this handler.
/changeset[/{revision}]
Show information about a single changeset.
A URL path argument is the changeset identifier to show. See hg help revisions for possible values. If
not defined, the tip changeset will be shown.
The changeset template is rendered. Contents of the changesettag, changesetbookmark, filenodelink,
filenolink, and the many templates related to diffs may all be used to produce the output.
/shortlog
Show basic information about a set of changesets.
This accepts the same parameters as the changelog handler. The only difference is the shortlog template
will be rendered instead of the changelog template.
/summary
Show a summary of repository state.
Information about the latest changesets, bookmarks, tags, and branches is captured by this handler.
The summary template is rendered.
/tags
Show information about tags.
No arguments are accepted.
The tags template is rendered.

MERGE TOOLS
To merge files Mercurial uses merge tools.
A merge tool combines two different versions of a file into a merged file. Merge tools are given the two
files and the greatest common ancestor of the two file versions, so they can determine the changes made
on both branches.
Merge tools are used both for hg resolve, hg merge, hg update, hg backout and in several extensions.
Usually, the merge tool tries to automatically reconcile the files by combining all non-overlapping
changes that occurred separately in the two different evolutions of the same initial base file.
Furthermore, some interactive merge programs make it easier to manually resolve conflicting merges,
either in a graphical way, or by inserting some conflict markers. Mercurial does not include any
interactive merge programs but relies on external tools for that.
Available merge tools
External merge tools and their properties are configured in the merge-tools configuration section - see
hgrc(5) - but they can often just be named by their executable.
A merge tool is generally usable if its executable can be found on the system and if it can handle the
merge. The executable is found if it is an absolute or relative executable path or the name of an
application in the executable search path. The tool is assumed to be able to handle the merge if it can
handle symlinks if the file is a symlink, if it can handle binary files if the file is binary, and if a
GUI is available if the tool requires a GUI.
There are some internal merge tools which can be used. The internal merge tools are:
:dump
Creates three versions of the files to merge, containing the contents of local, other and base.
These files can then be used to perform a merge manually. If the file to be merged is named a.txt,
these files will accordingly be named a.txt.local, a.txt.other and a.txt.base and they will be
placed in the same directory as a.txt.
This implies premerge. Therefore, files aren't dumped, if premerge runs successfully. Use
:forcedump to forcibly write files out.
(actual capabilities: binary, symlink)
:fail
Rather than attempting to merge files that were modified on both branches, it marks them as
unresolved. The resolve command must be used to resolve these conflicts.
(actual capabilities: binary, symlink)
:forcedump
Creates three versions of the files as same as :dump, but omits premerge.
(actual capabilities: binary, symlink)
:local
Uses the local p1() version of files as the merged version.
(actual capabilities: binary, symlink)
:merge
Uses the internal non-interactive simple merge algorithm for merging files. It will fail if there
are any conflicts and leave markers in the partially merged file. Markers will have two sections,
one for each side of merge.
:merge-local
Like :merge, but resolve all conflicts non-interactively in favor of the local p1() changes.
:merge-other
Like :merge, but resolve all conflicts non-interactively in favor of the other p2() changes.
:merge3
Uses the internal non-interactive simple merge algorithm for merging files. It will fail if there
are any conflicts and leave markers in the partially merged file. Marker will have three sections,
one from each side of the merge and one for the base content.
:mergediff
Uses the internal non-interactive simple merge algorithm for merging files. It will fail if there
are any conflicts and leave markers in the partially merged file. The marker will have two
sections, one with the content from one side of the merge, and one with a diff from the base
content to the content on the other side. (experimental)
:other
Uses the other p2() version of files as the merged version.
(actual capabilities: binary, symlink)
:prompt
Asks the user which of the local p1() or the other p2() version to keep as the merged version.
(actual capabilities: binary, symlink)
:tagmerge
Uses the internal tag merge algorithm (experimental).
:union
Uses the internal non-interactive simple merge algorithm for merging files. It will use both local
and other sides for conflict regions by adding local on top of other. No markers are inserted.
:union-other-first
Like :union, but add other on top of local.
Internal tools are always available and do not require a GUI but will by default not handle symlinks or
binary files. See next section for detail about "actual capabilities" described above.
Choosing a merge tool
Mercurial uses these rules when deciding which merge tool to use:
1. If a tool has been specified with the --tool option to merge or resolve, it is used. If it is the
name of a tool in the merge-tools configuration, its configuration is used. Otherwise the specified
tool must be executable by the shell.
2. If the HGMERGE environment variable is present, its value is used and must be executable by the shell.
3. If the filename of the file to be merged matches any of the patterns in the merge-patterns
configuration section, the first usable merge tool corresponding to a matching pattern is used.
4. If ui.merge is set it will be considered next. If the value is not the name of a configured tool, the
specified value is used and must be executable by the shell. Otherwise the named tool is used if it is
usable.
5. If any usable merge tools are present in the merge-tools configuration section, the one with the
highest priority is used.
6. If a program named hgmerge can be found on the system, it is used - but it will by default not be used
for symlinks and binary files.
7. If the file to be merged is not binary and is not a symlink, then internal :merge is used.
8. Otherwise, :prompt is used.
For historical reason, Mercurial treats merge tools as below while examining rules above.
┌────────────┬────────────────┬────────┬─────────┐
│ step │ specified via │ binary │ symlink │
├────────────┼────────────────┼────────┼─────────┤
│ │ --tool │ o/o │ o/o │
│ 1. │ │ │ │
├────────────┼────────────────┼────────┼─────────┤
│ │ HGMERGE │ o/o │ o/o │
│ 2. │ │ │ │
├────────────┼────────────────┼────────┼─────────┤
│ │ merge-patterns │ o/o(*) │ x/?(*) │
│ 3. │ │ │ │
├────────────┼────────────────┼────────┼─────────┤
│ │ ui.merge │ x/?(*) │ x/?(*) │
│ 4. │ │ │ │
└────────────┴────────────────┴────────┴─────────┘
Each capability column indicates Mercurial behavior for internal/external merge tools at examining each
rule.
• "o": "assume that a tool has capability"
• "x": "assume that a tool does not have capability"
• "?": "check actual capability of a tool"
If merge.strict-capability-check configuration is true, Mercurial checks capabilities of merge tools
strictly in (*) cases above (= each capability column becomes "?/?"). It is false by default for backward
compatibility.
Note After selecting a merge program, Mercurial will by default attempt to merge the files using a
simple merge algorithm first. Only if it doesn't succeed because of conflicting changes will
Mercurial actually execute the merge program. Whether to use the simple merge algorithm first can
be controlled by the premerge setting of the merge tool. Premerge is enabled by default unless the
file is binary or a symlink.
See the merge-tools and ui sections of hgrc(5) for details on the configuration of merge tools.
PAGER SUPPORT
Some Mercurial commands can produce a lot of output, and Mercurial will attempt to use a pager to make
those commands more pleasant.
To set the pager that should be used, set the application variable:
[pager]
pager = less -FRX
If no pager is set in the user or repository configuration, Mercurial uses the environment variable
$PAGER. If $PAGER is not set, pager.pager from the default or system configuration is used. If none of
these are set, a default pager will be used, typically less on Unix and more on Windows.
On Windows, more is not color aware, so using it effectively disables color. MSYS and Cygwin shells
provide less as a pager, which can be configured to support ANSI color codes. See hg help
config.color.pagermode to configure the color mode when invoking a pager.
You can disable the pager for certain commands by adding them to the pager.ignore list:
[pager]
ignore = version, help, update
To ignore global commands like hg version or hg help, you have to specify them in your user configuration
file.
To control whether the pager is used at all for an individual command, you can use --pager=<value>:
• use as needed: auto.
• require the pager: yes or on.
• suppress the pager: no or off (any unrecognized value will also work).
To globally turn off all attempts to use a pager, set:
[ui]
paginate = never
which will prevent the pager from running.
FILE NAME PATTERNS
Mercurial accepts several notations for identifying one or more files at a time.
By default, Mercurial treats filenames verbatim without pattern matching, relative to the current working
directory. Note that your system shell might perform pattern matching of its own before passing filenames
into Mercurial.
Alternate pattern notations must be specified explicitly.
Note Patterns specified in .hgignore are not rooted. Please see hg help hgignore for details.
To use a plain path name without any pattern matching, start it with path:. These path names must
completely match starting at the current repository root, and when the path points to a directory, it is
matched recursively. To match all files in a directory non-recursively (not including any files in
subdirectories), rootfilesin: can be used, specifying an absolute path (relative to the repository root).
To match a single file exactly, relative to the repository root, you can use filepath:.
To use an extended glob, start a name with glob:. Globs are rooted at the current directory; a glob such
as *.c will only match files in the current directory ending with .c. rootglob: can be used instead of
glob: for a glob that is rooted at the root of the repository.
The supported glob syntax extensions are ** to match any string across path separators and {a,b} to mean
"a or b".
To use a Perl/Python regular expression, start a name with re:. Regexp pattern matching is anchored at
the root of the repository.
To read name patterns from a file, use listfile: or listfile0:. The latter expects null delimited
patterns while the former expects line feeds. Each string read from the file is itself treated as a file
pattern.
To read a set of patterns from a file, use include: or subinclude:. include: will use all the patterns
from the given file and treat them as if they had been passed in manually. subinclude: will only apply
the patterns against files that are under the subinclude file's directory. See hg help hgignore for
details on the format of these files.
All patterns, except for glob: specified in command line (not for -I or -X options), can match also
against directories: files under matched directories are treated as matched. For -I and -X options,
glob: will match directories recursively.
Plain examples:
path:foo/bar a name bar in a directory named foo in the root
of the repository
path:some/path a file or directory named "some/path"
filepath:some/path/to/a/file exactly a single file named
"some/path/to/a/file", relative to the root
of the repository
rootfilesin:foo/bar the files in a directory called foo/bar, but
not any files in its subdirectories and not
a file bar in directory foo
Glob examples:
glob:*.c any name ending in ".c" in the current directory
*.c any name ending in ".c" in the current directory
**.c any name ending in ".c" in any subdirectory of the
current directory including itself.
foo/* any file in directory foo
foo/** any file in directory foo plus all its subdirectories,
recursively
foo/*.c any name ending in ".c" in the directory foo
foo/**.c any name ending in ".c" in any subdirectory of foo
including itself.
rootglob:*.c any name ending in ".c" in the root of the repository
Regexp examples:
re:.*\.c$ any name ending in ".c", anywhere in the repository
File examples:
listfile:list.txt read list from list.txt with one file pattern per line
listfile0:list.txt read list from list.txt with null byte delimiters
See also hg help filesets.
Include examples:
include:path/to/mypatternfile reads patterns to be applied to all paths
subinclude:path/to/subignorefile reads patterns specifically for paths in the
subdirectory
WORKING WITH PHASES
What are phases?
Phases are a system for tracking which changesets have been or should be shared. This helps prevent
common mistakes when modifying history (for instance, with the mq or rebase extensions).
Each changeset in a repository is in one of the following phases:
• public : changeset is visible on a public server
• draft : changeset is not yet published
• secret : changeset should not be pushed, pulled, or cloned
These phases are ordered (public < draft < secret) and no changeset can be in a lower phase than its
ancestors. For instance, if a changeset is public, all its ancestors are also public. Lastly, changeset
phases should only be changed towards the public phase.
How are phases managed?
For the most part, phases should work transparently. By default, a changeset is created in the draft
phase and is moved into the public phase when it is pushed to another repository.
Once changesets become public, extensions like mq and rebase will refuse to operate on them to prevent
creating duplicate changesets. Phases can also be manually manipulated with the hg phase command if
needed. See hg help -v phase for examples.
To make your commits secret by default, put this in your configuration file:
[phases]
new-commit = secret
Phases and servers
Normally, all servers are publishing by default. This means:
- all draft changesets that are pulled or cloned appear in phase
public on the client
- all draft changesets that are pushed appear as public on both
client and server
- secret changesets are neither pushed, pulled, or cloned
Note Pulling a draft changeset from a publishing server does not mark it as public on the server side
due to the read-only nature of pull.
Sometimes it may be desirable to push and pull changesets in the draft phase to share unfinished work.
This can be done by setting a repository to disable publishing in its configuration file:
[phases]
publish = False
See hg help config for more information on configuration files.
Note Servers running older versions of Mercurial are treated as publishing.
Note Changesets in secret phase are not exchanged with the server. This applies to their content: file
names, file contents, and changeset metadata. For technical reasons, the identifier (e.g.
d825e4025e39) of the secret changeset may be communicated to the server.
Examples
• list changesets in draft or secret phase:
hg log -r "not public()"
• change all secret changesets to draft:
hg phase --draft "secret()"
• forcibly move the current changeset and descendants from public to draft:
hg phase --force --draft .
• show a list of changeset revisions and each corresponding phase:
hg log --template "{rev} {phase}\n"
• resynchronize draft changesets relative to a remote repository:
hg phase -fd "outgoing(URL)"
See hg help phase for more information on manually manipulating phases.
SPECIFYING REVISIONS
Mercurial supports several ways to specify revisions.
Specifying single revisions
A plain integer is treated as a revision number. Negative integers are treated as sequential offsets from
the tip, with -1 denoting the tip, -2 denoting the revision prior to the tip, and so forth.
A 40-digit hexadecimal string is treated as a unique revision identifier. A hexadecimal string less than
40 characters long is treated as a unique revision identifier and is referred to as a short-form
identifier. A short-form identifier is only valid if it is the prefix of exactly one full-length
identifier.
Any other string is treated as a bookmark, tag, or branch name. A bookmark is a movable pointer to a
revision. A tag is a permanent name associated with a revision. A branch name denotes the tipmost open
branch head of that branch - or if they are all closed, the tipmost closed head of the branch. Bookmark,
tag, and branch names must not contain the ":" character.
The reserved name "tip" always identifies the most recent revision.
The reserved name "null" indicates the null revision. This is the revision of an empty repository, and
the parent of revision 0.
The reserved name "." indicates the working directory parent. If no working directory is checked out, it
is equivalent to null. If an uncommitted merge is in progress, "." is the revision of the first parent.
Finally, commands that expect a single revision (like hg update) also accept revsets (see below for
details). When given a revset, they use the last revision of the revset. A few commands accept two single
revisions (like hg diff). When given a revset, they use the first and the last revisions of the revset.
Specifying multiple revisions
Mercurial supports a functional language for selecting a set of revisions. Expressions in this language
are called revsets.
The language supports a number of predicates which are joined by infix operators. Parenthesis can be used
for grouping.
Identifiers such as branch names may need quoting with single or double quotes if they contain characters
like - or if they match one of the predefined predicates.
Special characters can be used in quoted identifiers by escaping them, e.g., \n is interpreted as a
newline. To prevent them from being interpreted, strings can be prefixed with r, e.g. r'...'.
Operators
There is a single prefix operator:
not x
Changesets not in x. Short form is ! x.
These are the supported infix operators:
x::y
A DAG range, meaning all changesets that are descendants of x and ancestors of y, including x and
y themselves. If the first endpoint is left out, this is equivalent to ancestors(y), if the second
is left out it is equivalent to descendants(x).
An alternative syntax is x..y.
x:y
All changesets with revision numbers between x and y, both inclusive. Either endpoint can be left
out, they default to 0 and tip.
x and y
The intersection of changesets in x and y. Short form is x & y.
x or y
The union of changesets in x and y. There are two alternative short forms: x | y and x + y.
x - y
Changesets in x but not in y.
x % y
Changesets that are ancestors of x but not ancestors of y (i.e. ::x - ::y). This is shorthand
notation for only(x, y) (see below). The second argument is optional and, if left out, is
equivalent to only(x).
x^n
The nth parent of x, n == 0, 1, or 2. For n == 0, x; for n == 1, the first parent of each
changeset in x; for n == 2, the second parent of changeset in x.
x~n
The nth first ancestor of x; x~0 is x; x~3 is x^^^. For n < 0, the nth unambiguous descendent of
x.
x ## y
Concatenate strings and identifiers into one string.
All other prefix, infix and postfix operators have lower priority than ##. For example, a1 ## a2~2
is equivalent to (a1 ## a2)~2.
For example:
[revsetalias]
issue(a1) = grep(r'\bissue[ :]?' ## a1 ## r'\b|\bbug\(' ## a1 ## r'\)')
issue(1234) is equivalent to grep(r'\bissue[ :]?1234\b|\bbug\(1234\)') in this case. This matches
against all of "issue 1234", "issue:1234", "issue1234" and "bug(1234)".
There is a single postfix operator:
x^
Equivalent to x^1, the first parent of each changeset in x.
Patterns
Where noted, predicates that perform string matching can accept a pattern string. The pattern may be
either a literal, or a regular expression. If the pattern starts with re:, the remainder of the pattern
is treated as a regular expression. Otherwise, it is treated as a literal. To match a pattern that
actually starts with re:, use the prefix literal:.
Matching is case-sensitive, unless otherwise noted. To perform a case- insensitive match on a
case-sensitive predicate, use a regular expression, prefixed with (?i).
For example, tag(r're:(?i)release') matches "release" or "RELEASE" or "Release", etc.
Predicates
The following predicates are supported:
adds(pattern)
Changesets that add a file matching pattern.
The pattern without explicit kind like glob: is expected to be relative to the current directory
and match against a file or a directory.
all()
All changesets, the same as 0:tip.
ancestor(*changeset)
A greatest common ancestor of the changesets.
Accepts 0 or more changesets. Will return empty list when passed no args. Greatest common
ancestor of a single changeset is that changeset.
ancestors(set[, depth])
Changesets that are ancestors of changesets in set, including the given changesets themselves.
If depth is specified, the result only includes changesets up to the specified generation.
author(string)
Alias for user(string).
bisect(string)
Changesets marked in the specified bisect status:
• good, bad, skip: csets explicitly marked as good/bad/skip
• goods, bads : csets topologically good/bad
• range : csets taking part in the bisection
• pruned : csets that are goods, bads or skipped
• untested : csets whose fate is yet unknown
• ignored : csets ignored due to DAG topology
• current : the cset currently being bisected
bookmark([name])
The named bookmark or all bookmarks.
Pattern matching is supported for name. See hg help revisions.patterns.
branch(string or set)
All changesets belonging to the given branch or the branches of the given changesets.
Pattern matching is supported for string. See hg help revisions.patterns.
branchpoint()
Changesets with more than one child.
bundle()
Changesets in the bundle.
Bundle must be specified by the -R option.
children(set)
Child changesets of changesets in set.
closed()
Changeset is closed.
commonancestors(set)
Changesets that are ancestors of every changeset in set.
conflictlocal()
The local side of the merge, if currently in an unresolved merge.
"merge" here includes merge conflicts from e.g. 'hg rebase' or 'hg graft'.
conflictother()
The other side of the merge, if currently in an unresolved merge.
"merge" here includes merge conflicts from e.g. 'hg rebase' or 'hg graft'.
contains(pattern)
The revision's manifest contains a file matching pattern (but might not modify it). See hg help
patterns for information about file patterns.
The pattern without explicit kind like glob: is expected to be relative to the current directory
and match against a file exactly for efficiency.
converted([id])
Changesets converted from the given identifier in the old repository if present, or all converted
changesets if no identifier is specified.
date(interval)
Changesets within the interval, see hg help dates.
desc(string)
Search commit message for string. The match is case-insensitive.
Pattern matching is supported for string. See hg help revisions.patterns.
descendants(set[, depth])
Changesets which are descendants of changesets in set, including the given changesets themselves.
If depth is specified, the result only includes changesets up to the specified generation.
destination([set])
Changesets that were created by a graft, transplant or rebase operation, with the given revisions
specified as the source. Omitting the optional set is the same as passing all().
diffcontains(pattern)
Search revision differences for when the pattern was added or removed.
The pattern may be a substring literal or a regular expression. See hg help revisions.patterns.
draft()
Changeset in draft phase.
expectsize(set[, size])
Return the given revset if size matches the revset size. Abort if the revset doesn't expect given
size. size can either be an integer range or an integer.
For example, expectsize(0:1, 3:5) will abort as revset size is 2 and 2 is not between 3 and 5
inclusive.
extra(label, [value])
Changesets with the given label in the extra metadata, with the given optional value.
Pattern matching is supported for value. See hg help revisions.patterns.
file(pattern)
Changesets affecting files matched by pattern.
For a faster but less accurate result, consider using filelog() instead.
This predicate uses glob: as the default kind of pattern.
filelog(pattern)
Changesets connected to the specified filelog.
For performance reasons, visits only revisions mentioned in the file-level filelog, rather than
filtering through all changesets (much faster, but doesn't include deletes or duplicate changes).
For a slower, more accurate result, use file().
The pattern without explicit kind like glob: is expected to be relative to the current directory
and match against a file exactly for efficiency.
first(set, [n])
An alias for limit().
follow([file[, startrev]])
An alias for ::. (ancestors of the working directory's first parent). If file pattern is
specified, the histories of files matching given pattern in the revision given by startrev are
followed, including copies.
followlines(file, fromline:toline[, startrev=., descend=False])
Changesets modifying file in line range ('fromline', 'toline').
Line range corresponds to 'file' content at 'startrev' and should hence be consistent with file
size. If startrev is not specified, working directory's parent is used.
By default, ancestors of 'startrev' are returned. If 'descend' is True, descendants of 'startrev'
are returned though renames are (currently) not followed in this direction.
grep(regex)
Like keyword(string) but accepts a regex. Use grep(r'...') to ensure special escape characters are
handled correctly. Unlike keyword(string), the match is case-sensitive.
head()
Changeset is a named branch head.
heads(set)
Members of set with no children in set.
hidden()
Hidden changesets.
id(string)
Revision non-ambiguously specified by the given hex string prefix.
keyword(string)
Search commit message, user name, and names of changed files for string. The match is
case-insensitive.
For a regular expression or case sensitive search of these fields, use grep(regex).
last(set, [n])
Last n members of set, defaulting to 1.
limit(set[, n[, offset]])
First n members of set, defaulting to 1, starting from offset.
matching(revision [, field])
Changesets in which a given set of fields match the set of fields in the selected revision or set.
To match more than one field pass the list of fields to match separated by spaces (e.g. author
description).
Valid fields are most regular revision fields and some special fields.
Regular revision fields are description, author, branch, date, files, phase, parents, substate,
user and diff. Note that author and user are synonyms. diff refers to the contents of the
revision. Two revisions matching their diff will also match their files.
Special fields are summary and metadata: summary matches the first line of the description.
metadata is equivalent to matching description user date (i.e. it matches the main metadata
fields).
metadata is the default field which is used when no fields are specified. You can match more than
one field at a time.
max(set)
Changeset with highest revision number in set.
merge()
Changeset is a merge changeset.
min(set)
Changeset with lowest revision number in set.
modifies(pattern)
Changesets modifying files matched by pattern.
The pattern without explicit kind like glob: is expected to be relative to the current directory
and match against a file or a directory.
named(namespace)
The changesets in a given namespace.
Pattern matching is supported for namespace. See hg help revisions.patterns.
nodefromfile(path)
Read a list of nodes from the file at path.
This applies id(LINE) to each line of the file.
This is useful when the amount of nodes you need to specify gets too large for the command line.
none()
No changesets.
only(set, [set])
Changesets that are ancestors of the first set that are not ancestors of any other head in the
repo. If a second set is specified, the result is ancestors of the first set that are not
ancestors of the second set (i.e. ::<set1> - ::<set2>).
origin([set])
Changesets that were specified as a source for the grafts, transplants or rebases that created the
given revisions. Omitting the optional set is the same as passing all(). If a changeset created
by these operations is itself specified as a source for one of these operations, only the source
changeset for the first operation is selected.
outgoing([path])
Changesets not found in the specified destination repository, or the default push location.
If the location resolve to multiple repositories, the union of all outgoing changeset will be
used.
p1([set])
First parent of changesets in set, or the working directory.
p2([set])
Second parent of changesets in set, or the working directory.
parents([set])
The set of all parents for all changesets in set, or the working directory.
present(set)
An empty set, if any revision in set isn't found; otherwise, all revisions in set.
If any of specified revisions is not present in the local repository, the query is normally
aborted. But this predicate allows the query to continue even in such cases.
public()
Changeset in public phase.
remote([id [,path]])
Local revision that corresponds to the given identifier in a remote repository, if present. Here,
the '.' identifier is a synonym for the current local branch.
removes(pattern)
Changesets which remove files matching pattern.
The pattern without explicit kind like glob: is expected to be relative to the current directory
and match against a file or a directory.
rev(number)
Revision with the given numeric identifier.
reverse(set)
Reverse order of set.
revset(set)
Strictly interpret the content as a revset.
The content of this special predicate will be strictly interpreted as a revset. For example,
revset(id(0)) will be interpreted as "id(0)" without possible ambiguity with a "id(0)" bookmark or
tag.
roots(set)
Changesets in set with no parent changeset in set.
secret()
Changeset in secret phase.
sort(set[, [-]key... [, ...]])
Sort set by keys. The default sort order is ascending, specify a key as -key to sort in descending
order.
The keys can be:
• rev for the revision number,
• branch for the branch name,
• desc for the commit message (description),
• user for user name (author can be used as an alias),
• date for the commit date
• topo for a reverse topographical sort
• node the nodeid of the revision
• random randomly shuffle revisions
The topo sort order cannot be combined with other sort keys. This sort takes one optional
argument, topo.firstbranch, which takes a revset that specifies what topographical branches to
prioritize in the sort.
The random sort takes one optional random.seed argument to control the pseudo-randomness of the
result.
subrepo([pattern])
Changesets that add, modify or remove the given subrepo. If no subrepo pattern is named, any
subrepo changes are returned.
tag([name])
The specified tag by name, or all tagged revisions if no name is given.
Pattern matching is supported for name. See hg help revisions.patterns.
user(string)
User name contains string. The match is case-insensitive.
Pattern matching is supported for string. See hg help revisions.patterns.
Aliases
New predicates (known as "aliases") can be defined, using any combination of existing predicates or other
aliases. An alias definition looks like:
<alias> = <definition>
in the revsetalias section of a Mercurial configuration file. Arguments of the form a1, a2, etc. are
substituted from the alias into the definition.
For example,
[revsetalias]
h = heads()
d(s) = sort(s, date)
rs(s, k) = reverse(sort(s, k))
defines three aliases, h, d, and rs. rs(0:tip, author) is exactly equivalent to reverse(sort(0:tip,
author)).
Equivalents
Command line equivalents for hg log:
-f -> ::.
-d x -> date(x)
-k x -> keyword(x)
-m -> merge()
-u x -> user(x)
-b x -> branch(x)
-P x -> !::x
-l x -> limit(expr, x)
Examples
Some sample queries:
• Changesets on the default branch:
hg log -r "branch(default)"
• Changesets on the default branch since tag 1.5 (excluding merges):
hg log -r "branch(default) and 1.5:: and not merge()"
• Open branch heads:
hg log -r "head() and not closed()"
• Changesets between tags 1.3 and 1.5 mentioning "bug" that affect hgext/*:
hg log -r "1.3::1.5 and keyword(bug) and file('hgext/*')"
• Changesets committed in May 2008, sorted by user:
hg log -r "sort(date('May 2008'), user)"
• Changesets mentioning "bug" or "issue" that are not in a tagged release:
hg log -r "(keyword(bug) or keyword(issue)) and not ancestors(tag())"
• Update to the commit that bookmark @ is pointing to, without activating the bookmark (this works
because the last revision of the revset is used):
hg update :@
• Show diff between tags 1.3 and 1.5 (this works because the first and the last revisions of the revset
are used):
hg diff -r 1.3::1.5
RUST IN MERCURIAL
Mercurial can be augmented with Rust extensions for speeding up certain operations.
Compatibility
Though the Rust extensions are only tested by the project under Linux, users of MacOS, FreeBSD and other
UNIX-likes have been using the Rust extensions. Your mileage may vary, but by all means do give us
feedback or signal your interest for better support.
No Rust extensions are available for Windows at this time.
Features
The following operations are sped up when using Rust:
• discovery of differences between repositories (pull/push)
• nodemap (see hg help config.format.use-persistent-nodemap)
• all commands using the dirstate (status, commit, diff, add, update, etc.)
• dirstate-v2 (see hg help config.format.use-dirstate-v2)
• iteration over ancestors in a graph
More features are in the works, and improvements on the above listed are still in progress. For more
experimental work see the "rhg" section.
Checking for Rust
You may already have the Rust extensions depending on how you install Mercurial:
$ hg debuginstall | grep -i rust
checking Rust extensions (installed)
checking module policy (rust+c-allow)
If those lines don't even exist, you're using an old version of hg which does not have any Rust
extensions yet.
Installing
You will need cargo to be in your $PATH. See the "MSRV" section for which version to use.
Using pip
Users of pip can install the Rust extensions with the following command:
$ pip install mercurial --global-option --rust --no-use-pep517
--no-use-pep517 is here to tell pip to preserve backwards compatibility with the legacy setup.py system.
Mercurial has not yet migrated its complex setup to the new system, so we still need this to add compiled
extensions.
This might take a couple of minutes because you're compiling everything.
See the "Checking for Rust" section to see if the install succeeded.
From your distribution
Some distributions are shipping Mercurial with Rust extensions enabled and pre-compiled (meaning you
won't have to install cargo), or allow you to specify an install flag. Check with your specific
distribution for how to do that, or ask their team to add support for hg+Rust!
From source
Please refer to the rust/README.rst file in the Mercurial repository for instructions on how to install
from source.
MSRV
The minimum supported Rust version is defined in rust/clippy.toml. The project's policy is to keep it at
or below the version from Debian testing, to make the distributions' job easier.
rhg
There exists an experimental pure-Rust version of Mercurial called rhg with a fallback mechanism for
unsupported invocations. It allows for much faster execution of certain commands while adding no
discernable overhead for the rest.
The only way of trying it out is by building it from source. Please refer to rust/README.rst in the
Mercurial repository.
See hg help config.rhg for configuration options.

USING MERCURIAL FROM SCRIPTS AND AUTOMATION
It is common for machines (as opposed to humans) to consume Mercurial. This help topic describes some of
the considerations for interfacing machines with Mercurial.
Choosing an Interface
Machines have a choice of several methods to interface with Mercurial. These include:
• Executing the hg process
• Querying a HTTP server
• Calling out to a command server
Executing hg processes is very similar to how humans interact with Mercurial in the shell. It should
already be familiar to you.
hg serve can be used to start a server. By default, this will start a "hgweb" HTTP server. This HTTP
server has support for machine-readable output, such as JSON. For more, see hg help hgweb.
hg serve can also start a "command server." Clients can connect to this server and issue Mercurial
commands over a special protocol. For more details on the command server, including links to client
libraries, see https://www.mercurial-scm.org/wiki/CommandServer.
hg serve based interfaces (the hgweb and command servers) have the advantage over simple hg process
invocations in that they are likely more efficient. This is because there is significant overhead to
spawn new Python processes.
Tip If you need to invoke several hg processes in short order and/or performance is important to you,
use of a server-based interface is highly recommended.
Environment Variables
As documented in hg help environment, various environment variables influence the operation of Mercurial.
The following are particularly relevant for machines consuming Mercurial:
HGPLAIN
If not set, Mercurial's output could be influenced by configuration settings that impact its
encoding, verbose mode, localization, etc.
It is highly recommended for machines to set this variable when invoking hg processes.
HGENCODING
If not set, the locale used by Mercurial will be detected from the environment. If the determined
locale does not support display of certain characters, Mercurial may render these character
sequences incorrectly (often by using "?" as a placeholder for invalid characters in the current
locale).
Explicitly setting this environment variable is a good practice to guarantee consistent results.
"utf-8" is a good choice on UNIX-like environments.
HGRCPATH
If not set, Mercurial will inherit config options from config files using the process described in
hg help config. This includes inheriting user or system-wide config files.
When utmost control over the Mercurial configuration is desired, the value of HGRCPATH can be set
to an explicit file with known good configs. In rare cases, the value can be set to an empty file
or the null device (often /dev/null) to bypass loading of any user or system config files. Note
that these approaches can have unintended consequences, as the user and system config files often
define things like the username and extensions that may be required to interface with a
repository.
HGRCSKIPREPO
When set, the .hg/hgrc from repositories are not read.
Note that not reading the repository's configuration can have unintended consequences, as the
repository config files can define things like extensions that are required for access to the
repository.
Command-line Flags
Mercurial's default command-line parser is designed for humans, and is not robust against malicious
input. For instance, you can start a debugger by passing --debugger as an option value:
$ REV=--debugger sh -c 'hg log -r "$REV"'
This happens because several command-line flags need to be scanned without using a concrete command
table, which may be modified while loading repository settings and extensions.
Since Mercurial 4.4.2, the parsing of such flags may be restricted by setting HGPLAIN=+strictflags. When
this feature is enabled, all early options (e.g. -R/--repository, --cwd, --config) must be specified
first amongst the other global options, and cannot be injected to an arbitrary location:
$ HGPLAIN=+strictflags hg -R "$REPO" log -r "$REV"
In earlier Mercurial versions where +strictflags isn't available, you can mitigate the issue by
concatenating an option value with its flag:
$ hg log -r"$REV" --keyword="$KEYWORD"
Consuming Command Output
It is common for machines to need to parse the output of Mercurial commands for relevant data. This
section describes the various techniques for doing so.
Parsing Raw Command Output
Likely the simplest and most effective solution for consuming command output is to simply invoke hg
commands as you would as a user and parse their output.
The output of many commands can easily be parsed with tools like grep, sed, and awk.
A potential downside with parsing command output is that the output of commands can change when Mercurial
is upgraded. While Mercurial does generally strive for strong backwards compatibility, command output
does occasionally change. Having tests for your automated interactions with hg commands is generally
recommended, but is even more important when raw command output parsing is involved.
Using Templates to Control Output
Many hg commands support templatized output via the -T/--template argument. For more, see hg help
templates.
Templates are useful for explicitly controlling output so that you get exactly the data you want
formatted how you want it. For example, log -T {node}\n can be used to print a newline delimited list of
changeset nodes instead of a human-tailored output containing authors, dates, descriptions, etc.
Tip If parsing raw command output is too complicated, consider using templates to make your life
easier.
The -T/--template argument allows specifying pre-defined styles. Mercurial ships with the
machine-readable styles cbor, json, and xml, which provide CBOR, JSON, and XML output, respectively.
These are useful for producing output that is machine readable as-is.
(Mercurial 5.0 is required for CBOR style.)
Important
The json and xml styles are considered experimental. While they may be attractive to use for
easily obtaining machine-readable output, their behavior may change in subsequent versions.
These styles may also exhibit unexpected results when dealing with certain encodings. Mercurial
treats things like filenames as a series of bytes and normalizing certain byte sequences to JSON
or XML with certain encoding settings can lead to surprises.
Command Server Output
If using the command server to interact with Mercurial, you are likely using an existing library/API that
abstracts implementation details of the command server. If so, this interface layer may perform parsing
for you, saving you the work of implementing it yourself.
Output Verbosity
Commands often have varying output verbosity, even when machine readable styles are being used (e.g. -T
json). Adding -v/--verbose and --debug to the command's arguments can increase the amount of data exposed
by Mercurial.
An alternate way to get the data you need is by explicitly specifying a template.
Other Topics
revsets
Revisions sets is a functional query language for selecting a set of revisions. Think of it as SQL
for Mercurial repositories. Revsets are useful for querying repositories for specific data.
See hg help revsets for more.
share extension
The share extension provides functionality for sharing repository data across several working
copies. It can even automatically "pool" storage for logically related repositories when cloning.
Configuring the share extension can lead to significant resource utilization reduction,
particularly around disk space and the network. This is especially true for continuous integration
(CI) environments.
See hg help -e share for more.
SUBREPOSITORIES
Subrepositories let you nest external repositories or projects into a parent Mercurial repository, and
make commands operate on them as a group.
Mercurial currently supports Mercurial, Git, and Subversion subrepositories.
Subrepositories are made of three components:
1. Nested repository checkouts. They can appear anywhere in the parent working directory.
2. Nested repository references. They are defined in .hgsub, which should be placed in the root of
working directory, and tell where the subrepository checkouts come from. Mercurial subrepositories are
referenced like:
path/to/nested = https://example.com/nested/repo/path
Git and Subversion subrepos are also supported:
path/to/nested = [git]git://example.com/nested/repo/path
path/to/nested = [svn]https://example.com/nested/trunk/path
where path/to/nested is the checkout location relatively to the parent Mercurial root, and
https://example.com/nested/repo/path is the source repository path. The source can also reference a
filesystem path.
Note that .hgsub does not exist by default in Mercurial repositories, you have to create and add it to
the parent repository before using subrepositories.
3. Nested repository states. They are defined in .hgsubstate, which is placed in the root of working
directory, and capture whatever information is required to restore the subrepositories to the state
they were committed in a parent repository changeset. Mercurial automatically record the nested
repositories states when committing in the parent repository.
Note
The .hgsubstate file should not be edited manually.
Adding a Subrepository
If .hgsub does not exist, create it and add it to the parent repository. Clone or checkout the external
projects where you want it to live in the parent repository. Edit .hgsub and add the subrepository entry
as described above. At this point, the subrepository is tracked and the next commit will record its state
in .hgsubstate and bind it to the committed changeset.
Synchronizing a Subrepository
Subrepos do not automatically track the latest changeset of their sources. Instead, they are updated to
the changeset that corresponds with the changeset checked out in the top-level changeset. This is so
developers always get a consistent set of compatible code and libraries when they update.
Thus, updating subrepos is a manual process. Simply check out target subrepo at the desired revision,
test in the top-level repo, then commit in the parent repository to record the new combination.
Deleting a Subrepository
To remove a subrepository from the parent repository, delete its reference from .hgsub, then remove its
files.
Interaction with Mercurial Commands
add add does not recurse in subrepos unless -S/--subrepos is specified. However, if you specify the
full path of a file in a subrepo, it will be added even without -S/--subrepos specified.
Subversion subrepositories are currently silently ignored.
addremove
addremove does not recurse into subrepos unless -S/--subrepos is specified. However, if you
specify the full path of a directory in a subrepo, addremove will be performed on it even without
-S/--subrepos being specified. Git and Subversion subrepositories will print a warning and
continue.
archive
archive does not recurse in subrepositories unless -S/--subrepos is specified.
cat Git subrepositories only support exact file matches. Subversion subrepositories are currently
ignored.
commit commit creates a consistent snapshot of the state of the entire project and its subrepositories.
If any subrepositories have been modified, Mercurial will abort. Mercurial can be made to instead
commit all modified subrepositories by specifying -S/--subrepos, or setting
"ui.commitsubrepos=True" in a configuration file (see hg help config). After there are no longer
any modified subrepositories, it records their state and finally commits it in the parent
repository. The --addremove option also honors the -S/--subrepos option. However, Git and
Subversion subrepositories will print a warning and abort.
diff diff does not recurse in subrepos unless -S/--subrepos is specified. However, if you specify the
full path of a file or directory in a subrepo, it will be diffed even without -S/--subrepos being
specified. Subversion subrepositories are currently silently ignored.
files files does not recurse into subrepos unless -S/--subrepos is specified. However, if you specify
the full path of a file or directory in a subrepo, it will be displayed even without -S/--subrepos
being specified. Git and Subversion subrepositories are currently silently ignored.
forget forget currently only handles exact file matches in subrepos. Git and Subversion subrepositories
are currently silently ignored.
incoming
incoming does not recurse in subrepos unless -S/--subrepos is specified. Git and Subversion
subrepositories are currently silently ignored.
outgoing
outgoing does not recurse in subrepos unless -S/--subrepos is specified. Git and Subversion
subrepositories are currently silently ignored.
pull pull is not recursive since it is not clear what to pull prior to running hg update. Listing and
retrieving all subrepositories changes referenced by the parent repository pulled changesets is
expensive at best, impossible in the Subversion case.
push Mercurial will automatically push all subrepositories first when the parent repository is being
pushed. This ensures new subrepository changes are available when referenced by top-level
repositories. Push is a no-op for Subversion subrepositories.
serve serve does not recurse into subrepositories unless -S/--subrepos is specified. Git and Subversion
subrepositories are currently silently ignored.
status status does not recurse into subrepositories unless -S/--subrepos is specified. Subrepository
changes are displayed as regular Mercurial changes on the subrepository elements. Subversion
subrepositories are currently silently ignored.
remove remove does not recurse into subrepositories unless -S/--subrepos is specified. However, if you
specify a file or directory path in a subrepo, it will be removed even without -S/--subrepos. Git
and Subversion subrepositories are currently silently ignored.
update update restores the subrepos in the state they were originally committed in target changeset. If
the recorded changeset is not available in the current subrepository, Mercurial will pull it in
first before updating. This means that updating can require network access when using
subrepositories.
Remapping Subrepositories Sources
A subrepository source location may change during a project life, invalidating references stored in the
parent repository history. To fix this, rewriting rules can be defined in parent repository hgrc file or
in Mercurial configuration. See the [subpaths] section in hgrc(5) for more details.
TEMPLATE USAGE
Mercurial allows you to customize output of commands through templates. You can either pass in a template
or select an existing template-style from the command line, via the --template option.
You can customize output for any "log-like" command: log, outgoing, incoming, tip, parents, and heads.
Some built-in styles are packaged with Mercurial. These can be listed with hg log --template list.
Example usage:
$ hg log -r1.0::1.1 --template changelog
A template is a piece of text, with markup to invoke variable expansion:
$ hg log -r1 --template "{node}\n"
b56ce7b07c52de7d5fd79fb89701ea538af65746
Keywords
Strings in curly braces are called keywords. The availability of keywords depends on the exact context of
the templater. These keywords are usually available for templating a log-like command:
_fast_rank
the rank of a changeset if cached
The rank of a revision is the size of the sub-graph it defines as a head. Equivalently, the rank
of a revision r is the size of the set ancestors(r), r included.
activebookmark
String. The active bookmark, if it is associated with the changeset.
author Alias for {user}
bisect String. The changeset bisection status.
bookmarks
List of strings. Any bookmarks associated with the changeset. Also sets 'active', the name of the
active bookmark.
branch String. The name of the branch on which the changeset was committed.
changessincelatesttag
Integer. All ancestors not in the latest tag.
children
List of strings. The children of the changeset.
date Date information. The date when the changeset was committed.
desc String. The text of the changeset description.
diffstat
String. Statistics of changes with the following format: "modified files: +added/-removed lines"
extras List of dicts with key, value entries of the 'extras' field of this changeset.
file_adds
List of strings. Files added by this changeset.
file_copies
List of strings. Files copied in this changeset with their sources.
file_copies_switch
List of strings. Like "file_copies" but displayed only if the --copied switch is set.
file_dels
List of strings. Files removed by this changeset.
file_mods
List of strings. Files modified by this changeset.
files List of strings. All files modified, added, or removed by this changeset.
graphnode
String. The character representing the changeset node in an ASCII revision graph.
graphwidth
Integer. The width of the graph drawn by 'log --graph' or zero.
index Integer. The current iteration of the loop. (0 indexed)
latesttag
List of strings. The global tags on the most recent globally tagged ancestor of this changeset.
If no such tags exist, the list consists of the single string "null".
latesttagdistance
Integer. Longest path to the latest tag.
namespaces
Dict of lists. Names attached to this changeset per namespace.
negrev Integer. The repository-local changeset negative revision number, which counts in the opposite
direction.
node String. The changeset identification hash, as a 40 hexadecimal digit string.
onelinesummary
String. A one-line summary for the ctx (not including trailing newline). The default template be
overridden in command-templates.oneline-summary.
p1 Changeset. The changeset's first parent. {p1.rev} for the revision number, and {p1.node} for the
identification hash.
p2 Changeset. The changeset's second parent. {p2.rev} for the revision number, and {p2.node} for the
identification hash.
parents
List of strings. The parents of the changeset in "rev:node" format. If the changeset has only one
"natural" parent (the predecessor revision) nothing is shown.
peerurls
A dictionary of repository locations defined in the [paths] section of your configuration file.
phase String. The changeset phase name.
reporoot
String. The root directory of the current repository.
rev Integer. The repository-local changeset revision number.
subrepos
List of strings. Updated subrepositories in the changeset.
tags List of strings. Any tags associated with the changeset.
termwidth
Integer. The width of the current terminal.
user String. The unmodified author of the changeset.
verbosity
String. The current output verbosity in 'debug', 'quiet', 'verbose', or ''.
The "date" keyword does not produce human-readable output. If you want to use a date in your output, you
can use a filter to process it. Filters are functions which return a string based on the input variable.
Be sure to use the stringify filter first when you're applying a string-input filter to a list-like input
variable. You can also use a chain of filters to get the desired output:
$ hg tip --template "{date|isodate}\n"
2008-08-21 18:22 +0000
Filters
List of filters:
addbreaks
Any text. Add an XHTML "<br />" tag before the end of every line except the last.
age Date. Returns a human-readable date/time difference between the given date/time and the current
date/time.
basename
Any text. Treats the text as a path, and returns the last component of the path after splitting by
the path separator. For example, "foo/bar/baz" becomes "baz" and "foo/bar//" becomes "".
cbor Any object. Serializes the object to CBOR bytes.
commondir
List of text. Treats each list item as file name with / as path separator and returns the longest
common directory prefix shared by all list items. Returns the empty string if no common prefix
exists.
The list items are not normalized, i.e. "foo/../bar" is handled as file "bar" in the directory
"foo/..". Leading slashes are ignored.
For example, ["foo/bar/baz", "foo/baz/bar"] becomes "foo" and ["foo/bar", "baz"] becomes "".
count List or text. Returns the length as an integer.
dirname
Any text. Treats the text as a path, and strips the last component of the path after splitting by
the path separator.
domain Any text. Finds the first string that looks like an email address, and extracts just the domain
component. Example: User <user@example.com> becomes example.com.
email Any text. Extracts the first string that looks like an email address. Example: User
<user@example.com> becomes user@example.com.
emailuser
Any text. Returns the user portion of an email address.
escape Any text. Replaces the special XML/XHTML characters "&", "<" and ">" with XML entities, and
filters out NUL characters.
fill68 Any text. Wraps the text to fit in 68 columns.
fill76 Any text. Wraps the text to fit in 76 columns.
firstline
Any text. Returns the first line of text.
hex Any text. Convert a binary Mercurial node identifier into its long hexadecimal representation.
hgdate Date. Returns the date as a pair of numbers: "1157407993 25200" (Unix timestamp, timezone offset).
isodate
Date. Returns the date in ISO 8601 format: "2009-08-18 13:00 +0200".
isodatesec
Date. Returns the date in ISO 8601 format, including seconds: "2009-08-18 13:00:13 +0200". See
also the rfc3339date filter.
json Any object. Serializes the object to a JSON formatted text.
lower Any text. Converts the text to lowercase.
nonempty
Any text. Returns '(none)' if the string is empty.
obfuscate
Any text. Returns the input text rendered as a sequence of XML entities.
person Any text. Returns the name before an email address, interpreting it as per RFC 5322.
reverse
List. Reverses the order of list items.
revescape
Any text. Escapes all "special" characters, except @. Forward slashes are escaped twice to
prevent web servers from prematurely unescaping them. For example, "@foo bar/baz" becomes
"@foo%20bar%252Fbaz".
rfc3339date
Date. Returns a date using the Internet date format specified in RFC 3339:
"2009-08-18T13:00:13+02:00".
rfc822date
Date. Returns a date using the same format used in email headers: "Tue, 18 Aug 2009 13:00:13
+0200".
short Changeset hash. Returns the short form of a changeset hash, i.e. a 12 hexadecimal digit string.
shortbisect
Any text. Treats label as a bisection status, and returns a single-character representing the
status (G: good, B: bad, S: skipped, U: untested, I: ignored). Returns single space if text is not
a valid bisection status.
shortdate
Date. Returns a date like "2006-09-18".
slashpath
Any text. Replaces the native path separator with slash.
splitlines
Any text. Split text into a list of lines.
stringify
Any type. Turns the value into text by converting values into text and concatenating them.
stripdir
Treat the text as path and strip a directory level, if possible. For example, "foo" and "foo/bar"
becomes "foo".
tabindent
Any text. Returns the text, with every non-empty line except the first starting with a tab
character.
upper Any text. Converts the text to uppercase.
urlescape
Any text. Escapes all "special" characters. For example, "foo bar" becomes "foo%20bar".
user Any text. Returns a short representation of a user name or email address.
utf8 Any text. Converts from the local character encoding to UTF-8.
Note that a filter is nothing more than a function call, i.e. expr|filter is equivalent to filter(expr).
Functions
In addition to filters, there are some basic built-in functions:
config(section, name[, default])
Returns the requested hgrc config option as a string.
configbool(section, name[, default])
Returns the requested hgrc config option as a boolean.
configint(section, name[, default])
Returns the requested hgrc config option as an integer.
date(date[, fmt])
Format a date. The format string uses the Python strftime format. The default is a Unix date
format, including the timezone: "Mon Sep 04 15:13:13 2006 0700".
dict([[key=]value...])
Construct a dict from key-value pairs. A key may be omitted if a value expression can provide an
unambiguous name.
diff([includepattern [, excludepattern]])
Show a diff, optionally specifying files to include or exclude.
files(pattern)
All files of the current changeset matching the pattern. See hg help patterns.
fill(text[, width[, initialident[, hangindent]]])
Fill many paragraphs with optional indentation. See the "fill" filter.
filter(iterable[, expr])
Remove empty elements from a list or a dict. If expr specified, it's applied to each element to
test emptiness.
get(dict, key)
Get an attribute/key from an object. Some keywords are complex types. This function allows you to
obtain the value of an attribute on these types.
if(expr, then[, else])
Conditionally execute based on the result of an expression.
ifcontains(needle, haystack, then[, else])
Conditionally execute based on whether the item "needle" is in "haystack".
ifeq(expr1, expr2, then[, else])
Conditionally execute based on whether 2 items are equivalent.
indent(text, indentchars[, firstline])
Indents all non-empty lines with the characters given in the indentchars string. An optional third
parameter will override the indent for the first line only if present.
join(list, sep)
Join items in a list with a delimiter.
label(label, expr)
Apply a label to generated content. Content with a label applied can result in additional
post-processing, such as automatic colorization. In order to receive effects, labels must have a
dot, such as log.secret or branch.active.
latesttag([pattern])
The global tags matching the given pattern on the most recent globally tagged ancestor of this
changeset. If no such tags exist, the "{tag}" template resolves to the string "null". See hg help
revisions.patterns for the pattern syntax.
localdate(date[, tz])
Converts a date to the specified timezone. The default is local date.
mailmap(author)
Return the author, updated according to the value set in the .mailmap file
max(iterable)
Return the max of an iterable
min(iterable)
Return the min of an iterable
mod(a, b)
Calculate a mod b such that a / b + a mod b == a
pad(text, width[, fillchar=' '[, left=False[, truncate=False]]])
Pad text with a fill character.
relpath(path)
Convert a repository-absolute path into a filesystem path relative to the current working
directory.
revset(query[, formatargs...])
Execute a revision set query. See hg help revset.
rstdoc(text, style)
Format reStructuredText.
search(pattern, text)
Look for the first text matching the regular expression pattern. Groups are accessible as {1},
{2}, ... in %-mapped template.
separate(sep, args...)
Add a separator between non-empty arguments.
shortest(node, minlength=4)
Obtain the shortest representation of a node.
startswith(pattern, text)
Returns the value from the "text" argument if it begins with the content from the "pattern"
argument.
strip(text[, chars])
Strip characters from a string. By default, strips all leading and trailing whitespace.
sub(pattern, replacement, expression)
Perform text substitution using regular expressions.
subsetparents(rev, revset)
Look up parents of the rev in the sub graph given by the revset.
word(number, text[, separator])
Return the nth word from a string.
Operators
We provide a limited set of infix arithmetic operations on integers:
+ for addition
- for subtraction
* for multiplication
/ for floor division (division rounded to integer nearest -infinity)
Division fulfills the law x = x / y + mod(x, y).
Also, for any expression that returns a list, there is a list operator:
expr % "{template}"
As seen in the above example, {template} is interpreted as a template. To prevent it from being
interpreted, you can use an escape character \{ or a raw string prefix, r'...'.
The dot operator can be used as a shorthand for accessing a sub item:
• expr.member is roughly equivalent to expr % '{member}' if expr returns a non-list/dict. The returned
value is not stringified.
• dict.key is identical to get(dict, 'key').
Aliases
New keywords and functions can be defined in the templatealias section of a Mercurial configuration file:
<alias> = <definition>
Arguments of the form a1, a2, etc. are substituted from the alias into the definition.
For example,
[templatealias]
r = rev
rn = "{r}:{node|short}"
leftpad(s, w) = pad(s, w, ' ', True)
defines two symbol aliases, r and rn, and a function alias leftpad().
It's also possible to specify complete template strings, using the templates section. The syntax used is
the general template string syntax.
For example,
[templates]
nodedate = "{node|short}: {date(date, "%Y-%m-%d")}\n"
defines a template, nodedate, which can be called like:
$ hg log -r . -Tnodedate
A template defined in templates section can also be referenced from another template:
$ hg log -r . -T "{rev} {nodedate}"
but be aware that the keywords cannot be overridden by templates. For example, a template defined as
templates.rev cannot be referenced as {rev}.
A template defined in templates section may have sub templates which are inserted before/after/between
items:
[templates]
myjson = ' {dict(rev, node|short)|json}'
myjson:docheader = '\{\n'
myjson:docfooter = '\n}\n'
myjson:separator = ',\n'
Examples
Some sample command line templates:
• Format lists, e.g. files:
$ hg log -r 0 --template "files:\n{files % ' {file}\n'}"
• Join the list of files with a ", ":
$ hg log -r 0 --template "files: {join(files, ', ')}\n"
• Join the list of files ending with ".py" with a ", ":
$ hg log -r 0 --template "pythonfiles: {join(files('**.py'), ', ')}\n"
• Separate non-empty arguments by a " ":
$ hg log -r 0 --template "{separate(' ', node, bookmarks, tags}\n"
• Modify each line of a commit description:
$ hg log --template "{splitlines(desc) % '**** {line}\n'}"
• Format date:
$ hg log -r 0 --template "{date(date, '%Y')}\n"
• Display date in UTC:
$ hg log -r 0 --template "{localdate(date, 'UTC')|date}\n"
• Output the description set to a fill-width of 30:
$ hg log -r 0 --template "{fill(desc, 30)}"
• Use a conditional to test for the default branch:
$ hg log -r 0 --template "{ifeq(branch, 'default', 'on the main branch',
'on branch {branch}')}\n"
• Append a newline if not empty:
$ hg tip --template "{if(author, '{author}\n')}"
• Label the output for use with the color extension:
$ hg log -r 0 --template "{label('changeset.{phase}', node|short)}\n"
• Invert the firstline filter, i.e. everything but the first line:
$ hg log -r 0 --template "{sub(r'^.*\n?\n?', '', desc)}\n"
• Display the contents of the 'extra' field, one per line:
$ hg log -r 0 --template "{join(extras, '\n')}\n"
• Mark the active bookmark with '*':
$ hg log --template "{bookmarks % '{bookmark}{ifeq(bookmark, active, '*')} '}\n"
• Find the previous release candidate tag, the distance and changes since the tag:
$ hg log -r . --template "{latesttag('re:^.*-rc$') % '{tag}, {changes}, {distance}'}\n"
• Mark the working copy parent with '@':
$ hg log --template "{ifcontains(rev, revset('.'), '@')}\n"
• Show details of parent revisions:
$ hg log --template "{revset('parents(%d)', rev) % '{desc|firstline}\n'}"
• Show only commit descriptions that start with "template":
$ hg log --template "{startswith('template', firstline(desc))}\n"
• Print the first word of each line of a commit message:
$ hg log --template "{word(0, desc)}\n"
URL PATHS
Valid URLs are of the form:
local/filesystem/path[#revision]
file://local/filesystem/path[#revision]
http://[user[:pass]@]host[:port]/[path][#revision]
https://[user[:pass]@]host[:port]/[path][#revision]
ssh://[user@]host[:port]/[path][#revision]
path://pathname
Paths in the local filesystem can either point to Mercurial repositories or to bundle files (as created
by hg bundle or hg incoming --bundle). See also hg help paths.
An optional identifier after # indicates a particular branch, tag, or changeset to use from the remote
repository. See also hg help revisions.
Some features, such as pushing to http:// and https:// URLs are only possible if the feature is
explicitly enabled on the remote Mercurial server.
Note that the security of HTTPS URLs depends on proper configuration of web.cacerts.
Some notes about using SSH with Mercurial:
• SSH requires an accessible shell account on the destination machine and a copy of hg in the remote path
or specified with remotecmd.
• path is relative to the remote user's home directory by default. Use an extra slash at the start of a
path to specify an absolute path:
ssh://example.com//tmp/repository
• Mercurial doesn't use its own compression via SSH; the right thing to do is to configure it in your
~/.ssh/config, e.g.:
Host *.mylocalnetwork.example.com
Compression no
Host *
Compression yes
Alternatively specify "ssh -C" as your ssh command in your configuration file or with the --ssh command
line option.
These URLs can all be stored in your configuration file with path aliases under the [paths] section like
so:
[paths]
alias1 = URL1
alias2 = URL2
...
You can then use the alias for any command that uses a URL (for example hg pull alias1 will be treated as
hg pull URL1).
Two path aliases are special because they are used as defaults when you do not provide the URL to a
command:
default:
When you create a repository with hg clone, the clone command saves the location of the source
repository as the new repository's 'default' path. This is then used when you omit path from push-
and pull-like commands (including incoming and outgoing).
default-push:
The push command will look for a path named 'default-push', and prefer it over 'default' if both
are defined.
These alias can also be use in the path:// scheme:
[paths]
alias1 = URL1
alias2 = path://alias1
...
check hg help config.paths for details about the behavior of such "sub-path".
EXTENSIONS
This section contains help for extensions that are distributed together with Mercurial. Help for other
extensions is available in the help system.
absorb
apply working directory changes to changesets (EXPERIMENTAL)
The absorb extension provides a command to use annotate information to amend modified chunks into the
corresponding non-public changesets.
[absorb]
# only check 50 recent non-public changesets at most
max-stack-size = 50
# whether to add noise to new commits to avoid obsolescence cycle
add-noise = 1
# make `amend --correlated` a shortcut to the main command
amend-flag = correlated
[color]
absorb.description = yellow
absorb.node = blue bold
absorb.path = bold
Commands
Change creation
absorb
incorporate corrections into the stack of draft changesets:
hg absorb [OPTION] [FILE]...
absorb analyzes each change in your working directory and attempts to amend the changed lines into the
changesets in your stack that first introduced those lines.
If absorb cannot find an unambiguous changeset to amend for a change, that change will be left in the
working directory, untouched. They can be observed by hg status or hg diff afterwards. In other words,
absorb does not write to the working directory.
Changesets outside the revset ::. and not public() and not merge() will not be changed.
Changesets that become empty after applying the changes will be deleted.
By default, absorb will show what it plans to do and prompt for confirmation. If you are confident that
the changes will be absorbed to the correct place, run hg absorb -a to apply the changes immediately.
Returns 0 on success, 1 if all chunks were ignored and nothing amended.
Options:
-a, --apply-changes
apply changes without prompting for confirmation
-p, --print-changes
always print which changesets are modified by which changes
-i, --interactive
interactively select which chunks to apply
-e, --edit-lines
edit what lines belong to which changesets before commit (EXPERIMENTAL)
-n, --dry-run
do not perform actions, just print output
--style <STYLE>
display using template map file (DEPRECATED)
-T,--template <TEMPLATE>
display with template
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
[+] marked option can be specified multiple times
acl
hooks for controlling repository access
This hook makes it possible to allow or deny write access to given branches and paths of a repository
when receiving incoming changesets via pretxnchangegroup and pretxncommit.
The authorization is matched based on the local user name on the system where the hook runs, and not the
committer of the original changeset (since the latter is merely informative).
The acl hook is best used along with a restricted shell like hgsh, preventing authenticating users from
doing anything other than pushing or pulling. The hook is not safe to use if users have interactive shell
access, as they can then disable the hook. Nor is it safe if remote users share an account, because then
there is no way to distinguish them.
The order in which access checks are performed is:
1. Deny list for branches (section acl.deny.branches)
2. Allow list for branches (section acl.allow.branches)
3. Deny list for paths (section acl.deny)
4. Allow list for paths (section acl.allow)
The allow and deny sections take key-value pairs.
Branch-based Access Control
Use the acl.deny.branches and acl.allow.branches sections to have branch-based access control. Keys in
these sections can be either:
• a branch name, or
• an asterisk, to match any branch;
The corresponding values can be either:
• a comma-separated list containing users and groups, or
• an asterisk, to match anyone;
You can add the "!" prefix to a user or group name to invert the sense of the match.
Path-based Access Control
Use the acl.deny and acl.allow sections to have path-based access control. Keys in these sections accept
a subtree pattern (with a glob syntax by default). The corresponding values follow the same syntax as the
other sections above.
Bookmark-based Access Control
Use the acl.deny.bookmarks and acl.allow.bookmarks sections to have bookmark-based access control. Keys
in these sections can be either:
• a bookmark name, or
• an asterisk, to match any bookmark;
The corresponding values can be either:
• a comma-separated list containing users and groups, or
• an asterisk, to match anyone;
You can add the "!" prefix to a user or group name to invert the sense of the match.
Note: for interactions between clients and servers using Mercurial 3.6+ a rejection will generally reject
the entire push, for interactions involving older clients, the commit transactions will already be
accepted, and only the bookmark movement will be rejected.
Groups
Group names must be prefixed with an @ symbol. Specifying a group name has the same effect as specifying
all the users in that group.
You can define group members in the acl.groups section. If a group name is not defined there, and
Mercurial is running under a Unix-like system, the list of users will be taken from the OS. Otherwise,
an exception will be raised.
Example Configuration
[hooks]
# Use this if you want to check access restrictions at commit time
pretxncommit.acl = python:hgext.acl.hook
# Use this if you want to check access restrictions for pull, push,
# bundle and serve.
pretxnchangegroup.acl = python:hgext.acl.hook
[acl]
# Allow or deny access for incoming changes only if their source is
# listed here, let them pass otherwise. Source is "serve" for all
# remote access (http or ssh), "push", "pull" or "bundle" when the
# related commands are run locally.
# Default: serve
sources = serve
[acl.deny.branches]
# Everyone is denied to the frozen branch:
frozen-branch = *
# A bad user is denied on all branches:
* = bad-user
[acl.allow.branches]
# A few users are allowed on branch-a:
branch-a = user-1, user-2, user-3
# Only one user is allowed on branch-b:
branch-b = user-1
# The super user is allowed on any branch:
* = super-user
# Everyone is allowed on branch-for-tests:
branch-for-tests = *
[acl.deny]
# This list is checked first. If a match is found, acl.allow is not
# checked. All users are granted access if acl.deny is not present.
# Format for both lists: glob pattern = user, ..., @group, ...
# To match everyone, use an asterisk for the user:
# my/glob/pattern = *
# user6 will not have write access to any file:
** = user6
# Group "hg-denied" will not have write access to any file:
** = @hg-denied
# Nobody will be able to change "DONT-TOUCH-THIS.txt", despite
# everyone being able to change all other files. See below.
src/main/resources/DONT-TOUCH-THIS.txt = *
[acl.allow]
# if acl.allow is not present, all users are allowed by default
# empty acl.allow = no users allowed
# User "doc_writer" has write access to any file under the "docs"
# folder:
docs/** = doc_writer
# User "jack" and group "designers" have write access to any file
# under the "images" folder:
images/** = jack, @designers
# Everyone (except for "user6" and "@hg-denied" - see acl.deny above)
# will have write access to any file under the "resources" folder
# (except for 1 file. See acl.deny):
src/main/resources/** = *
.hgtags = release_engineer
Examples using the ! prefix
Suppose there's a branch that only a given user (or group) should be able to push to, and you don't want
to restrict access to any other branch that may be created.
The "!" prefix allows you to prevent anyone except a given user or group to push changesets in a given
branch or path.
In the examples below, we will: 1) Deny access to branch "ring" to anyone but user "gollum" 2) Deny
access to branch "lake" to anyone but members of the group "hobbit" 3) Deny access to a file to anyone
but user "gollum"
[acl.allow.branches]
# Empty
[acl.deny.branches]
# 1) only 'gollum' can commit to branch 'ring';
# 'gollum' and anyone else can still commit to any other branch.
ring = !gollum
# 2) only members of the group 'hobbit' can commit to branch 'lake';
# 'hobbit' members and anyone else can still commit to any other branch.
lake = !@hobbit
# You can also deny access based on file paths:
[acl.allow]
# Empty
[acl.deny]
# 3) only 'gollum' can change the file below;
# 'gollum' and anyone else can still change any other file.
/misty/mountains/cave/ring = !gollum

bugzilla
hooks for integrating with the Bugzilla bug tracker
This hook extension adds comments on bugs in Bugzilla when changesets that refer to bugs by Bugzilla ID
are seen. The comment is formatted using the Mercurial template mechanism.
The bug references can optionally include an update for Bugzilla of the hours spent working on the bug.
Bugs can also be marked fixed.
Four basic modes of access to Bugzilla are provided:
1. Access via the Bugzilla REST-API. Requires bugzilla 5.0 or later.
2. Access via the Bugzilla XMLRPC interface. Requires Bugzilla 3.4 or later.
3. Check data via the Bugzilla XMLRPC interface and submit bug change via email to Bugzilla email
interface. Requires Bugzilla 3.4 or later.
4. Writing directly to the Bugzilla database. Only Bugzilla installations using MySQL are supported.
Requires Python MySQLdb.
Writing directly to the database is susceptible to schema changes, and relies on a Bugzilla contrib
script to send out bug change notification emails. This script runs as the user running Mercurial, must
be run on the host with the Bugzilla install, and requires permission to read Bugzilla configuration
details and the necessary MySQL user and password to have full access rights to the Bugzilla database.
For these reasons this access mode is now considered deprecated, and will not be updated for new Bugzilla
versions going forward. Only adding comments is supported in this access mode.
Access via XMLRPC needs a Bugzilla username and password to be specified in the configuration. Comments
are added under that username. Since the configuration must be readable by all Mercurial users, it is
recommended that the rights of that user are restricted in Bugzilla to the minimum necessary to add
comments. Marking bugs fixed requires Bugzilla 4.0 and later.
Access via XMLRPC/email uses XMLRPC to query Bugzilla, but sends email to the Bugzilla email interface to
submit comments to bugs. The From: address in the email is set to the email address of the Mercurial
user, so the comment appears to come from the Mercurial user. In the event that the Mercurial user email
is not recognized by Bugzilla as a Bugzilla user, the email associated with the Bugzilla username used to
log into Bugzilla is used instead as the source of the comment. Marking bugs fixed works on all supported
Bugzilla versions.
Access via the REST-API needs either a Bugzilla username and password or an apikey specified in the
configuration. Comments are made under the given username or the user associated with the apikey in
Bugzilla.
Configuration items common to all access modes:
bugzilla.version
The access type to use. Values recognized are:
restapi
Bugzilla REST-API, Bugzilla 5.0 and later.
xmlrpc
Bugzilla XMLRPC interface.
xmlrpc+email
Bugzilla XMLRPC and email interfaces.
3.0
MySQL access, Bugzilla 3.0 and later.
2.18
MySQL access, Bugzilla 2.18 and up to but not including 3.0.
2.16
MySQL access, Bugzilla 2.16 and up to but not including 2.18.
bugzilla.regexp
Regular expression to match bug IDs for update in changeset commit message. It must contain one
"()" named group <ids> containing the bug IDs separated by non-digit characters. It may also
contain a named group <hours> with a floating-point number giving the hours worked on the bug. If
no named groups are present, the first "()" group is assumed to contain the bug IDs, and work time
is not updated. The default expression matches Bug 1234, Bug no. 1234, Bug number 1234, Bugs
1234,5678, Bug 1234 and 5678 and variations thereof, followed by an hours number prefixed by h or
hours, e.g. hours 1.5. Matching is case insensitive.
bugzilla.fixregexp
Regular expression to match bug IDs for marking fixed in changeset commit message. This must
contain a "()" named group <ids>` containing the bug IDs separated by non-digit characters. It may
also contain a named group ``<hours> with a floating-point number giving the hours worked on the
bug. If no named groups are present, the first "()" group is assumed to contain the bug IDs, and
work time is not updated. The default expression matches Fixes 1234, Fixes bug 1234, Fixes bugs
1234,5678, Fixes 1234 and 5678 and variations thereof, followed by an hours number prefixed by h
or hours, e.g. hours 1.5. Matching is case insensitive.
bugzilla.fixstatus
The status to set a bug to when marking fixed. Default RESOLVED.
bugzilla.fixresolution
The resolution to set a bug to when marking fixed. Default FIXED.
bugzilla.style
The style file to use when formatting comments.
bugzilla.template
Template to use when formatting comments. Overrides style if specified. In addition to the usual
Mercurial keywords, the extension specifies:
{bug}
The Bugzilla bug ID.
{root}
The full pathname of the Mercurial repository.
{webroot}
Stripped pathname of the Mercurial repository.
{hgweb}
Base URL for browsing Mercurial repositories.
Default changeset {node|short} in repo {root} refers to bug {bug}.\ndetails:\n\t{desc|tabindent}
bugzilla.strip
The number of path separator characters to strip from the front of the Mercurial repository path
({root} in templates) to produce {webroot}. For example, a repository with {root}
/var/local/my-project with a strip of 2 gives a value for {webroot} of my-project. Default 0.
web.baseurl
Base URL for browsing Mercurial repositories. Referenced from templates as {hgweb}.
Configuration items common to XMLRPC+email and MySQL access modes:
bugzilla.usermap
Path of file containing Mercurial committer email to Bugzilla user email mappings. If specified,
the file should contain one mapping per line:
committer = Bugzilla user
See also the [usermap] section.
The [usermap] section is used to specify mappings of Mercurial committer email to Bugzilla user email.
See also bugzilla.usermap. Contains entries of the form committer = Bugzilla user.
XMLRPC and REST-API access mode configuration:
bugzilla.bzurl
The base URL for the Bugzilla installation. Default http://localhost/bugzilla.
bugzilla.user
The username to use to log into Bugzilla via XMLRPC. Default bugs.
bugzilla.password
The password for Bugzilla login.
REST-API access mode uses the options listed above as well as:
bugzilla.apikey
An apikey generated on the Bugzilla instance for api access. Using an apikey removes the need to
store the user and password options.
XMLRPC+email access mode uses the XMLRPC access mode configuration items, and also:
bugzilla.bzemail
The Bugzilla email address.
In addition, the Mercurial email settings must be configured. See the documentation in hgrc(5), sections
[email] and [smtp].

Bugzilla user.
bugzilla.bzdir
Bugzilla install directory. Used by default notify. Default /var/www/html/bugzilla.
bugzilla.notify
The command to run to get Bugzilla to send bug change notification emails. Substitutes from a map
with 3 keys, bzdir, id (bug id) and user (committer bugzilla email). Default depends on version;
from 2.18 it is "cd %(bzdir)s && perl -T contrib/sendbugmail.pl %(id)s %(user)s".

censor
erase file content at a given revision
The censor command instructs Mercurial to erase all content of a file at a given revision without
updating the changeset hash. This allows existing history to remain valid while preventing future
clones/pulls from receiving the erased data.
Typical uses for censor are due to security or legal requirements, including:
* Passwords, private keys, cryptographic material
* Licensed data/code/libraries for which the license has expired
* Personally Identifiable Information or other private data
Censored nodes can interrupt mercurial's typical operation whenever the excised data needs to be
materialized. Some commands, like hg cat/hg revert, simply fail when asked to produce censored data.
Others, like hg verify and hg update, must be capable of tolerating censored data to continue to function
in a meaningful way. Such commands only tolerate censored file As having a censored version in a checkout
is impractical. The current head revisions of the repository are checked. If the revision to be censored
is in any of them the command will abort.
A few informative commands such as hg grep will unconditionally ignore censored data and merely report
that it was encountered.
Commands
Repository maintenance
censor
hg censor -r REV [-t TEXT] [FILE]
Options:
-r,--rev <REV[+]>
censor file from specified revision
--check-heads
check that repository heads are not affected (default: True)
-t,--tombstone <TEXT>
replacement tombstone data
[+] marked option can be specified multiple times
children
command to display child changesets (DEPRECATED)
This extension is deprecated. You should use hg log -r "children(REV)" instead.
Commands
Change navigation
children
show the children of the given or working directory revision:
hg children [-r REV] [FILE]
Print the children of the working directory's revisions. If a revision is given via -r/--rev, the
children of that revision will be printed. If a file argument is given, revision in which the file was
last changed (after the working directory revision or the argument to --rev if given) is printed.
Please use hg log instead:
hg children => hg log -r "children(.)"
hg children -r REV => hg log -r "children(REV)"
See hg help log and hg help revsets.children.
Options:
-r,--rev <REV>
show children of the specified revision (default: .)
--style <STYLE>
display using template map file (DEPRECATED)
-T,--template <TEMPLATE>
display with template
churn
command to display statistics about repository history
Commands
Repository maintenance
churn
histogram of changes to the repository:
hg churn [-d DATE] [-r REV] [--aliases FILE] [FILE]
This command will display a histogram representing the number of changed lines or revisions, grouped
according to the given template. The default template will group changes by author. The --dateformat
option may be used to group the results by date instead.
Statistics are based on the number of changed lines, or alternatively the number of matching revisions if
the --changesets option is specified.
Examples:
# display count of changed lines for every committer
hg churn -T "{author|email}"
# display daily activity graph
hg churn -f "%H" -s -c
# display activity of developers by month
hg churn -f "%Y-%m" -s -c
# display count of lines changed in every year
hg churn -f "%Y" -s
# display count of lines changed in a time range
hg churn -d "2020-04 to 2020-09"
It is possible to map alternate email addresses to a main address by providing a file using the following
format:
<alias email> = <actual email>
Such a file may be specified with the --aliases option, otherwise a .hgchurn file will be looked for in
the working directory root. Aliases will be split from the rightmost "=".
Options:
-r,--rev <REV[+]>
count rate for the specified revision or revset
-d,--date <DATE>
count rate for revisions matching date spec

--diffstat
display added/removed lines separately
--aliases <FILE>
file with email aliases
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns

clonebundles
advertise pre-generated bundles to seed clones
"clonebundles" is a server-side extension used to advertise the existence of pre-generated, externally
hosted bundle files to clients that are cloning so that cloning can be faster, more reliable, and require
less resources on the server. "pullbundles" is a related feature for sending pre-generated bundle files
to clients as part of pull operations.
Cloning can be a CPU and I/O intensive operation on servers. Traditionally, the server, in response to a
client's request to clone, dynamically generates a bundle containing the entire repository content and
sends it to the client. There is no caching on the server and the server will have to redundantly
generate the same outgoing bundle in response to each clone request. For servers with large repositories
or with high clone volume, the load from clones can make scaling the server challenging and costly.
This extension provides server operators the ability to offload potentially expensive clone load to an
external service. Pre-generated bundles also allow using more CPU intensive compression, reducing the
effective bandwidth requirements.
Here's how clone bundles work:
1. A server operator establishes a mechanism for making bundle files available on a hosting service where
Mercurial clients can fetch them.
2. A manifest file listing available bundle URLs and some optional metadata is added to the Mercurial
repository on the server.
3. A client initiates a clone against a clone bundles aware server.
4. The client sees the server is advertising clone bundles and fetches the manifest listing available
bundles.
5. The client filters and sorts the available bundles based on what it supports and prefers.
6. The client downloads and applies an available bundle from the server-specified URL.
7. The client reconnects to the original server and performs the equivalent of hg pull to retrieve all
repository data not in the bundle. (The repository could have been updated between when the bundle was
created and when the client started the clone.) This may use "pullbundles".
Instead of the server generating full repository bundles for every clone request, it generates full
bundles once and they are subsequently reused to bootstrap new clones. The server may still transfer data
at clone time. However, this is only data that has been added/changed since the bundle was created. For
large, established repositories, this can reduce server load for clones to less than 1% of original.
Here's how pullbundles work:
1. A manifest file listing available bundles and describing the revisions is added to the Mercurial
repository on the server.
2. A new-enough client informs the server that it supports partial pulls and initiates a pull.
3. If the server has pull bundles enabled and sees the client advertising partial pulls, it checks for a
matching pull bundle in the manifest. A bundle matches if the format is supported by the client, the
client has the required revisions already and needs something from the bundle.
4. If there is at least one matching bundle, the server sends it to the client.
5. The client applies the bundle and notices that the server reply was incomplete. It initiates another
pull.
To work, this extension requires the following of server operators:
• Generating bundle files of repository content (typically periodically, such as once per day).
• Clone bundles: A file server that clients have network access to and that Python knows how to talk to
through its normal URL handling facility (typically an HTTP/HTTPS server).
• A process for keeping the bundles manifest in sync with available bundle files.
Strictly speaking, using a static file hosting server isn't required: a server operator could use a
dynamic service for retrieving bundle data. However, static file hosting services are simple and scalable
and should be sufficient for most needs.
Bundle files can be generated with the hg bundle command. Typically hg bundle --all is used to produce a
bundle of the entire repository.
The bundlespec option stream (see hg help bundlespec) can be used to produce a special streaming
clonebundle, typically using hg bundle --all --type="none-streamv2". These are bundle files that are
extremely efficient to produce and consume (read: fast). However, they are larger than traditional bundle
formats and require that clients support the exact set of repository data store formats in use by the
repository that created them. Typically, a newer server can serve data that is compatible with older
clients. However, streaming clone bundles don't have this guarantee. Server operators need to be aware
that newer versions of Mercurial may produce streaming clone bundles incompatible with older Mercurial
versions.
A server operator is responsible for creating a .hg/clonebundles.manifest file containing the list of
available bundle files suitable for seeding clones. If this file does not exist, the repository will not
advertise the existence of clone bundles when clients connect. For pull bundles, .hg/pullbundles.manifest
is used.
The manifest file contains a newline (n) delimited list of entries.
Each line in this file defines an available bundle. Lines have the format:
<URL> [<key>=<value>[ <key>=<value>]]
That is, a URL followed by an optional, space-delimited list of key=value pairs describing additional
properties of this bundle. Both keys and values are URI encoded.
For pull bundles, the URL is a path under the .hg directory of the repository.
Keys in UPPERCASE are reserved for use by Mercurial and are defined below. All non-uppercase keys can be
used by site installations. An example use for custom properties is to use the datacenter attribute to
define which data center a file is hosted in. Clients could then prefer a server in the data center
closest to them.
The following reserved keys are currently defined:
BUNDLESPEC
A "bundle specification" string that describes the type of the bundle.
These are string values that are accepted by the "--type" argument of hg bundle.
The values are parsed in strict mode, which means they must be of the "<compression>-<type>" form.
See mercurial.exchange.parsebundlespec() for more details.
hg debugbundle --spec can be used to print the bundle specification string for a bundle file. The
output of this command can be used verbatim for the value of BUNDLESPEC (it is already escaped).
Clients will automatically filter out specifications that are unknown or unsupported so they won't
attempt to download something that likely won't apply.
The actual value doesn't impact client behavior beyond filtering: clients will still sniff the
bundle type from the header of downloaded files.
Use of this key is highly recommended, as it allows clients to easily skip unsupported bundles. If
this key is not defined, an old client may attempt to apply a bundle that it is incapable of
reading.
REQUIRESNI
Whether Server Name Indication (SNI) is required to connect to the URL. SNI allows servers to use
multiple certificates on the same IP. It is somewhat common in CDNs and other hosting providers.
Older Python versions do not support SNI. Defining this attribute enables clients with older
Python versions to filter this entry without experiencing an opaque SSL failure at connection
time.
If this is defined, it is important to advertise a non-SNI fallback URL or clients running old
Python releases may not be able to clone with the clonebundles facility.
Value should be "true".
REQUIREDRAM
Value specifies expected memory requirements to decode the payload. Values can have suffixes for
common bytes sizes. e.g. "64MB".
This key is often used with zstd-compressed bundles using a high compression level / window size,
which can require 100+ MB of memory to decode.
heads Used for pull bundles. This contains the ; separated changeset hashes of the heads of the bundle
content.
bases Used for pull bundles. This contains the ; separated changeset hashes of the roots of the bundle
content. This can be skipped if the bundle was created without --base.
Manifests can contain multiple entries. Assuming metadata is defined, clients will filter entries from
the manifest that they don't support. The remaining entries are optionally sorted by client preferences
(ui.clonebundleprefers config option). The client then attempts to fetch the bundle at the first URL in
the remaining list.
Errors when downloading a bundle will fail the entire clone operation: clients do not automatically fall
back to a traditional clone. The reason for this is that if a server is using clone bundles, it is
probably doing so because the feature is necessary to help it scale. In other words, there is an
assumption that clone load will be offloaded to another service and that the Mercurial server isn't
responsible for serving this clone load. If that other service experiences issues and clients start mass
falling back to the original Mercurial server, the added clone load could overwhelm the server due to
unexpected load and effectively take it offline. Not having clients automatically fall back to cloning
from the original server mitigates this scenario.
Because there is no automatic Mercurial server fallback on failure of the bundle hosting service, it is
important for server operators to view the bundle hosting service as an extension of the Mercurial server
in terms of availability and service level agreements: if the bundle hosting service goes down, so does
the ability for clients to clone. Note: clients will see a message informing them how to bypass the clone
bundles facility when a failure occurs. So server operators should prepare for some people to follow
these instructions when a failure occurs, thus driving more load to the original Mercurial server when
the bundle hosting service fails.
inline clonebundles
It is possible to transmit clonebundles inline in case repositories are accessed over SSH. This avoids
having to setup an external HTTPS server and results in the same access control as already present for
the SSH setup.
Inline clonebundles should be placed into the .hg/bundle-cache directory. A clonebundle at
.hg/bundle-cache/mybundle.bundle is referred to in the clonebundles.manifest file as
peer-bundle-cache://mybundle.bundle.
auto-generation of clone bundles
It is possible to set Mercurial to automatically re-generate clone bundles when enough new content is
available.
Mercurial will take care of the process asynchronously. The defined list of bundle-type will be
generated, uploaded, and advertised. Older bundles will get decommissioned as newer ones replace them.
Bundles Generation:
The extension can generate multiple variants of the clone bundle. Each different variant will be defined
by the "bundle-spec" they use:
[clone-bundles]
auto-generate.formats= zstd-v2, gzip-v2
See hg help bundlespec for details about available options.
By default, new bundles are generated when 5% of the repository contents or at least 1000 revisions are
not contained in the cached bundles. This option can be controlled by the
clone-bundles.trigger.below-bundled-ratio option (default 0.95) and the clone-bundles.trigger.revs option
(default 1000):
[clone-bundles]
trigger.below-bundled-ratio=0.95
trigger.revs=1000
This logic can be manually triggered using the admin::clone-bundles-refresh command, or automatically on
each repository change if clone-bundles.auto-generate.on-change is set to yes:
[clone-bundles]
auto-generate.on-change=yes
auto-generate.formats= zstd-v2, gzip-v2
Automatic Inline serving
The simplest way to serve the generated bundle is through the Mercurial protocol. However it is not the
most efficient as request will still be served by that main server. It is useful in case where
authentication is complexe or when an efficient mirror system is already in use anyway. See the inline
clonebundles section above for details about inline clonebundles
To automatically serve generated bundle through inline clonebundle, simply set the following option:
auto-generate.serve-inline=yes
Enabling this option disable the managed upload and serving explained below.
Bundles Upload and Serving:
This is the most efficient way to serve automatically generated clone bundles, but requires some setup.
The generated bundles need to be made available to users through a "public" URL. This should be donne
through clone-bundles.upload-command configuration. The value of this command should be a shell command.
It will have access to the bundle file path through the $HGCB_BUNDLE_PATH variable. And the expected
basename in the "public" URL is accessible at:
[clone-bundles]
upload-command=sftp put $HGCB_BUNDLE_PATH sftp://bundles.host/clone-bundles/$HGCB_BUNDLE_BASENAME
If the file was already uploaded, the command must still succeed.
After upload, the file should be available at an url defined by clone-bundles.url-template.
[clone-bundles] url-template=https://bundles.host/cache/clone-bundles/{basename}
Old bundles cleanup:
When new bundles are generated, the older ones are no longer necessary and can be removed from storage.
This is done through the clone-bundles.delete-command configuration. The command is given the url of the
artifact to delete through the $HGCB_BUNDLE_URL environment variable.
[clone-bundles] delete-command=sftp rm sftp://bundles.host/clone-bundles/$HGCB_BUNDLE_BASENAME
If the file was already deleted, the command must still succeed.

convert
import revisions from foreign VCS repositories into Mercurial
Commands
Uncategorized commands
convert
convert a foreign SCM repository to a Mercurial one.:
hg convert [OPTION]... SOURCE [DEST [REVMAP]]
Accepted source formats [identifiers]:
• Mercurial [hg]
• CVS [cvs]
• Darcs [darcs]
• git [git]
• Subversion [svn]
• Monotone [mtn]
• GNU Arch [gnuarch]
• Bazaar [bzr]
• Perforce [p4]
Accepted destination formats [identifiers]:
• Mercurial [hg]
• Subversion [svn] (history on branches is not preserved)
If no revision is given, all revisions will be converted. Otherwise, convert will only import up to the
named revision (given in a format understood by the source).
If no destination directory name is specified, it defaults to the basename of the source with -hg
appended. If the destination repository doesn't exist, it will be created.
By default, all sources except Mercurial will use --branchsort. Mercurial uses --sourcesort to preserve
original revision numbers order. Sort modes have the following effects:
--branchsort
convert from parent to child revision when possible, which means branches are usually converted
one after the other. It generates more compact repositories.
--datesort
sort revisions by date. Converted repositories have good-looking changelogs but are often an order
of magnitude larger than the same ones generated by --branchsort.
--sourcesort
try to preserve source revisions order, only supported by Mercurial sources.
--closesort
try to move closed revisions as close as possible to parent branches, only supported by Mercurial
sources.
If REVMAP isn't given, it will be put in a default location (<dest>/.hg/shamap by default). The REVMAP is
a simple text file that maps each source commit ID to the destination ID for that revision, like so:
<source ID> <destination ID>
If the file doesn't exist, it's automatically created. It's updated on each commit copied, so hg convert
can be interrupted and can be run repeatedly to copy new commits.
The authormap is a simple text file that maps each source commit author to a destination commit author.
It is handy for source SCMs that use unix logins to identify authors (e.g.: CVS). One line per author
mapping and the line format is:
source author = destination author
Empty lines and lines starting with a # are ignored.
The filemap is a file that allows filtering and remapping of files and directories. Each line can contain
one of the following directives:
include path/to/file-or-dir
exclude path/to/file-or-dir
rename path/to/source path/to/destination
Comment lines start with #. A specified path matches if it equals the full relative name of a file or one
of its parent directories. The include or exclude directive with the longest matching path applies, so
line order does not matter.
The include directive causes a file, or all files under a directory, to be included in the destination
repository. The default if there are no include statements is to include everything. If there are any
include statements, nothing else is included. The exclude directive causes files or directories to be
omitted. The rename directive renames a file or directory if it is converted. To rename from a
subdirectory into the root of the repository, use . as the path to rename to.
--full will make sure the converted changesets contain exactly the right files with the right content. It
will make a full conversion of all files, not just the ones that have changed. Files that already are
correct will not be changed. This can be used to apply filemap changes when converting incrementally.
This is currently only supported for Mercurial and Subversion.
The splicemap is a file that allows insertion of synthetic history, letting you specify the parents of a
revision. This is useful if you want to e.g. give a Subversion merge two parents, or graft two
disconnected series of history together. Each entry contains a key, followed by a space, followed by one
or two comma-separated values:
key parent1, parent2
The key is the revision ID in the source revision control system whose parents should be modified (same
format as a key in .hg/shamap). The values are the revision IDs (in either the source or destination
revision control system) that should be used as the new parents for that node. For example, if you have
merged "release-1.0" into "trunk", then you should specify the revision on "trunk" as the first parent
and the one on the "release-1.0" branch as the second.
The branchmap is a file that allows you to rename a branch when it is being brought in from whatever
external repository. When used in conjunction with a splicemap, it allows for a powerful combination to
help fix even the most badly mismanaged repositories and turn them into nicely structured Mercurial
repositories. The branchmap contains lines of the form:
original_branch_name new_branch_name
where "original_branch_name" is the name of the branch in the source repository, and "new_branch_name" is
the name of the branch is the destination repository. No whitespace is allowed in the new branch name.
This can be used to (for instance) move code in one repository from "default" to a named branch.
Mercurial Source
The Mercurial source recognizes the following configuration options, which you can set on the command
line with --config:
convert.hg.ignoreerrors
ignore integrity errors when reading. Use it to fix Mercurial repositories with missing revlogs,
by converting from and to Mercurial. Default is False.
convert.hg.saverev
store original revision ID in changeset (forces target IDs to change). It takes a boolean argument
and defaults to False.
convert.hg.startrev
specify the initial Mercurial revision. The default is 0.
convert.hg.revs
revset specifying the source revisions to convert.
Bazaar Source
The following options can be used with --config:
convert.bzr.saverev
whether to store the original Bazaar commit ID in the metadata of the destination commit. The
default is True.
CVS Source
CVS source will use a sandbox (i.e. a checked-out copy) from CVS to indicate the starting point of what
will be converted. Direct access to the repository files is not needed, unless of course the repository
is :local:. The conversion uses the top level directory in the sandbox to find the CVS repository, and
then uses CVS rlog commands to find files to convert. This means that unless a filemap is given, all
files under the starting directory will be converted, and that any directory reorganization in the CVS
sandbox is ignored.
The following options can be used with --config:
convert.cvsps.cache
Set to False to disable remote log caching, for testing and debugging purposes. Default is True.
convert.cvsps.fuzz
Specify the maximum time (in seconds) that is allowed between commits with identical user and log
message in a single changeset. When very large files were checked in as part of a changeset then
the default may not be long enough. The default is 60.
convert.cvsps.logencoding
Specify encoding name to be used for transcoding CVS log messages. Multiple encoding names can be
specified as a list (see hg help config.Syntax), but only the first acceptable encoding in the
list is used per CVS log entries. This transcoding is executed before cvslog hook below.
convert.cvsps.mergeto
Specify a regular expression to which commit log messages are matched. If a match occurs, then the
conversion process will insert a dummy revision merging the branch on which this log message
occurs to the branch indicated in the regex. Default is {{mergetobranch ([-\w]+)}}
convert.cvsps.mergefrom
Specify a regular expression to which commit log messages are matched. If a match occurs, then the
conversion process will add the most recent revision on the branch indicated in the regex as the
second parent of the changeset. Default is {{mergefrombranch ([-\w]+)}}
convert.localtimezone
use local time (as determined by the TZ environment variable) for changeset date/times. The
default is False (use UTC).
hooks.cvslog
Specify a Python function to be called at the end of gathering the CVS log. The function is passed
a list with the log entries, and can modify the entries in-place, or add or delete them.
hooks.cvschangesets
Specify a Python function to be called after the changesets are calculated from the CVS log. The
function is passed a list with the changeset entries, and can modify the changesets in-place, or
add or delete them.
An additional "debugcvsps" Mercurial command allows the builtin changeset merging code to be run without
doing a conversion. Its parameters and output are similar to that of cvsps 2.1. Please see the command
help for more details.
Subversion Source
Subversion source detects classical trunk/branches/tags layouts. By default, the supplied
svn://repo/path/ source URL is converted as a single branch. If svn://repo/path/trunk exists it replaces
the default branch. If svn://repo/path/branches exists, its subdirectories are listed as possible
branches. If svn://repo/path/tags exists, it is looked for tags referencing converted branches. Default
trunk, branches and tags values can be overridden with following options. Set them to paths relative to
the source URL, or leave them blank to disable auto detection.
The following options can be set with --config:
convert.svn.branches
specify the directory containing branches. The default is branches.
convert.svn.tags
specify the directory containing tags. The default is tags.
convert.svn.trunk
specify the name of the trunk branch. The default is trunk.
convert.localtimezone
use local time (as determined by the TZ environment variable) for changeset date/times. The
default is False (use UTC).
Source history can be retrieved starting at a specific revision, instead of being integrally converted.
Only single branch conversions are supported.
convert.svn.startrev
specify start Subversion revision number. The default is 0.
Git Source
The Git importer converts commits from all reachable branches (refs in refs/heads) and remotes (refs in
refs/remotes) to Mercurial. Branches are converted to bookmarks with the same name, with the leading
'refs/heads' stripped. Git submodules are converted to Git subrepos in Mercurial.
The following options can be set with --config:
convert.git.similarity
specify how similar files modified in a commit must be to be imported as renames or copies, as a
percentage between 0 (disabled) and 100 (files must be identical). For example, 90 means that a
delete/add pair will be imported as a rename if more than 90% of the file hasn't changed. The
default is 50.
convert.git.findcopiesharder
while detecting copies, look at all files in the working copy instead of just changed ones. This
is very expensive for large projects, and is only effective when convert.git.similarity is greater
than 0. The default is False.
convert.git.renamelimit
perform rename and copy detection up to this many changed files in a commit. Increasing this will
make rename and copy detection more accurate but will significantly slow down computation on large
projects. The option is only relevant if convert.git.similarity is greater than 0. The default is
400.
convert.git.committeractions
list of actions to take when processing author and committer values.
Git commits have separate author (who wrote the commit) and committer (who applied the commit)
fields. Not all destinations support separate author and committer fields (including Mercurial).
This config option controls what to do with these author and committer fields during conversion.
A value of messagedifferent will append a committer: ... line to the commit message if the Git
committer is different from the author. The prefix of that line can be specified using the syntax
messagedifferent=<prefix>. e.g. messagedifferent=git-committer:. When a prefix is specified, a
space will always be inserted between the prefix and the value.
messagealways behaves like messagedifferent except it will always result in a committer: ... line
being appended to the commit message. This value is mutually exclusive with messagedifferent.
dropcommitter will remove references to the committer. Only references to the author will remain.
Actions that add references to the committer will have no effect when this is set.
replaceauthor will replace the value of the author field with the committer. Other actions that
add references to the committer will still take effect when this is set.
The default is messagedifferent.
convert.git.extrakeys
list of extra keys from commit metadata to copy to the destination. Some Git repositories store
extra metadata in commits. By default, this non-default metadata will be lost during conversion.
Setting this config option can retain that metadata. Some built-in keys such as parent and branch
are not allowed to be copied.
convert.git.remoteprefix
remote refs are converted as bookmarks with convert.git.remoteprefix as a prefix followed by a /.
The default is 'remote'.
convert.git.saverev
whether to store the original Git commit ID in the metadata of the destination commit. The default
is True.
convert.git.skipsubmodules
does not convert root level .gitmodules files or files with 160000 mode indicating a submodule.
Default is False.
Perforce Source
The Perforce (P4) importer can be given a p4 depot path or a client specification as source. It will
convert all files in the source to a flat Mercurial repository, ignoring labels, branches and
integrations. Note that when a depot path is given you then usually should specify a target directory,
because otherwise the target may be named ...-hg.
The following options can be set with --config:
convert.p4.encoding
specify the encoding to use when decoding standard output of the Perforce command line tool. The
default is default system encoding.
convert.p4.startrev
specify initial Perforce revision (a Perforce changelist number).
Mercurial Destination
The Mercurial destination will recognize Mercurial subrepositories in the destination directory, and
update the .hgsubstate file automatically if the destination subrepositories contain the
<dest>/<sub>/.hg/shamap file. Converting a repository with subrepositories requires converting a single
repository at a time, from the bottom up.
An example showing how to convert a repository with subrepositories:
# so convert knows the type when it sees a non empty destination
$ hg init converted
$ hg convert orig/sub1 converted/sub1
$ hg convert orig/sub2 converted/sub2
$ hg convert orig converted
The following options are supported:
convert.hg.clonebranches
dispatch source branches in separate clones. The default is False.
convert.hg.tagsbranch
branch name for tag revisions, defaults to default.
convert.hg.usebranchnames
preserve branch names. The default is True.
convert.hg.sourcename
records the given string as a 'convert_source' extra value on each commit made in the target
repository. The default is None.
convert.hg.preserve-hash
only works with mercurial sources. Make convert prevent performance improvement to the list of
modified files in commits when such an improvement would cause the hash of a commit to change.
The default is False.
All Destinations
All destination types accept the following options:
convert.skiptags
does not convert tags from the source repo to the target repo. The default is False.
Subversion Destination
Original commit dates are not preserved by default.
convert.svn.dangerous-set-commit-dates
preserve original commit dates, forcefully setting svn:date revision properties. This option is
DANGEROUS and may break some subversion functionality for the resulting repository (e.g. filtering
revisions with date ranges in svn log), as original commit dates are not guaranteed to be
monotonically increasing.
For commit dates setting to work destination repository must have pre-revprop-change hook configured to
allow setting of svn:date revision properties. See Subversion documentation for more details.
Options:
--authors <FILE>
username mapping filename (DEPRECATED) (use --authormap instead)
-s,--source-type <TYPE>

eol
automatically manage newlines in repository files
This extension allows you to manage the type of line endings (CRLF or LF) that are used in the repository
and in the local working directory. That way you can get CRLF line endings on Windows and LF on Unix/Mac,
thereby letting everybody use their OS native line endings.
The extension reads its configuration from a versioned .hgeol configuration file found in the root of the
working directory. The .hgeol file use the same syntax as all other Mercurial configuration files. It
uses two sections, [patterns] and [repository].
The [patterns] section specifies how line endings should be converted between the working directory and
the repository. The format is specified by a file pattern. The first match is used, so put more specific
patterns first. The available line endings are LF, CRLF, and BIN.
Files with the declared format of CRLF or LF are always checked out and stored in the repository in that
format and files declared to be binary (BIN) are left unchanged. Additionally, native is an alias for
checking out in the platform's default line ending: LF on Unix (including Mac OS X) and CRLF on Windows.
Note that BIN (do nothing to line endings) is Mercurial's default behavior; it is only needed if you need
to override a later, more general pattern.
The optional [repository] section specifies the line endings to use for files stored in the repository.
It has a single setting, native, which determines the storage line endings for files declared as native
in the [patterns] section. It can be set to LF or CRLF. The default is LF. For example, this means that
on Windows, files configured as native (CRLF by default) will be converted to LF when stored in the
repository. Files declared as LF, CRLF, or BIN in the [patterns] section are always stored as-is in the
repository.
Example versioned .hgeol file:
[patterns]
**.py = native
**.vcproj = CRLF
**.txt = native
Makefile = LF
**.jpg = BIN
[repository]
native = LF
Note The rules will first apply when files are touched in the working directory, e.g. by updating to
null and back to tip to touch all files.
The extension uses an optional [eol] section read from both the normal Mercurial configuration files and
the .hgeol file, with the latter overriding the former. You can use that section to control the overall
behavior. There are three settings:
• eol.native (default os.linesep) can be set to LF or CRLF to override the default interpretation of
native for checkout. This can be used with hg archive on Unix, say, to generate an archive where files
have line endings for Windows.
• eol.only-consistent (default True) can be set to False to make the extension convert files with
inconsistent EOLs. Inconsistent means that there is both CRLF and LF present in the file. Such files
are normally not touched under the assumption that they have mixed EOLs on purpose.
• eol.fix-trailing-newline (default False) can be set to True to ensure that converted files end with a
EOL character (either \n or \r\n as per the configured patterns).
The extension provides cleverencode: and cleverdecode: filters like the deprecated win32text extension
does. This means that you can disable win32text and enable eol and your filters will still work. You only
need to these filters until you have prepared a .hgeol file.
The win32text.forbid* hooks provided by the win32text extension have been unified into a single hook
named eol.checkheadshook. The hook will lookup the expected line endings from the .hgeol file, which
means you must migrate to a .hgeol file first before using the hook. eol.checkheadshook only checks
heads, intermediate invalid revisions will be pushed. To forbid them completely, use the eol.checkallhook
hook. These hooks are best used as pretxnchangegroup hooks.
See hg help patterns for more information about the glob patterns used.
extdiff
command to allow external programs to compare revisions
The extdiff Mercurial extension allows you to use external programs to compare revisions, or revision
with working directory. The external diff programs are called with a configurable set of options and two
non-option arguments: paths to directories containing snapshots of files to compare.
If there is more than one file being compared and the "child" revision is the working directory, any
modifications made in the external diff program will be copied back to the working directory from the
temporary directory.
The extdiff extension also allows you to configure new diff commands, so you do not need to type hg
extdiff -p kdiff3 always.
[extdiff]
# add new command that runs GNU diff(1) in 'context diff' mode
cdiff = gdiff -Nprc5
## or the old way:
#cmd.cdiff = gdiff
#opts.cdiff = -Nprc5
# add new command called meld, runs meld (no need to name twice). If
# the meld executable is not available, the meld tool in [merge-tools]
# will be used, if available
meld =
# add new command called vimdiff, runs gvimdiff with DirDiff plugin
# (see http://www.vim.org/scripts/script.php?script_id=102) Non
# English user, be sure to put "let g:DirDiffDynamicDiffText = 1" in
# your .vimrc
vimdiff = gvim -f "+next" \
"+execute 'DirDiff' fnameescape(argv(0)) fnameescape(argv(1))"
Tool arguments can include variables that are expanded at runtime:
$parent1, $plabel1 - filename, descriptive label of first parent
$child, $clabel - filename, descriptive label of child revision
$parent2, $plabel2 - filename, descriptive label of second parent
$root - repository root
$parent is an alias for $parent1.
The extdiff extension will look in your [diff-tools] and [merge-tools] sections for diff tool arguments,
when none are specified in [extdiff].
[extdiff]
kdiff3 =
[diff-tools]
kdiff3.diffargs=--L1 '$plabel1' --L2 '$clabel' $parent $child
If a program has a graphical interface, it might be interesting to tell Mercurial about it. It will
prevent the program from being mistakenly used in a terminal-only environment (such as an SSH terminal
session), and will make hg extdiff --per-file open multiple file diffs at once instead of one by one (if
you still want to open file diffs one by one, you can use the --confirm option).
Declaring that a tool has a graphical interface can be done with the gui flag next to where diffargs are
specified:
[diff-tools]
kdiff3.diffargs=--L1 '$plabel1' --L2 '$clabel' $parent $child
kdiff3.gui = true
You can use -I/-X and list of file or directory names like normal hg diff command. The extdiff extension
makes snapshots of only needed files, so running the external diff program will actually be pretty fast
(at least faster than having to compare the entire tree).
Commands
File content management
extdiff
use external program to diff repository (or selected files):
hg extdiff [OPT]... [FILE]...
Show differences between revisions for the specified files, using an external program. The default
program used is diff, with default options "-Npru".
To select a different program, use the -p/--program option. The program will be passed the names of two
directories to compare, unless the --per-file option is specified (see below). To pass additional options
to the program, use -o/--option. These will be passed before the names of the directories or files to
compare.
The --from, --to, and --change options work the same way they do for hg diff.
The --per-file option runs the external program repeatedly on each file to diff, instead of once on two
directories. By default, this happens one by one, where the next file diff is open in the external
program only once the previous external program (for the previous file diff) has exited. If the external
program has a graphical interface, it can open all the file diffs at once instead of one by one. See hg
help -e extdiff for information about how to tell Mercurial that a given program has a graphical
interface.
The --confirm option will prompt the user before each invocation of the external program. It is ignored
if --per-file isn't specified.

factotum
http authentication with factotum
This extension allows the factotum(4) facility on Plan 9 from Bell Labs platforms to provide
authentication information for HTTP access. Configuration entries specified in the auth section as well
as authentication information provided in the repository URL are fully supported. If no prefix is
specified, a value of "*" will be assumed.
By default, keys are specified as:
proto=pass service=hg prefix=<prefix> user=<username> !password=<password>
If the factotum extension is unable to read the required key, one will be requested interactively.
A configuration section is available to customize runtime behavior. By default, these entries are:
[factotum]
executable = /bin/auth/factotum
mountpoint = /mnt/factotum
service = hg
The executable entry defines the full path to the factotum binary. The mountpoint entry defines the path
to the factotum file service. Lastly, the service entry controls the service name used when reading keys.
fastannotate
yet another annotate implementation that might be faster (EXPERIMENTAL)
The fastannotate extension provides a 'fastannotate' command that makes use of the linelog data structure
as a cache layer and is expected to be faster than the vanilla 'annotate' if the cache is present.
In most cases, fastannotate requires a setup that mainbranch is some pointer that always moves forward,
to be most efficient.
Using fastannotate together with linkrevcache would speed up building the annotate cache greatly. Run
"debugbuildlinkrevcache" before "debugbuildannotatecache".
[fastannotate]
# specify the main branch head. the internal linelog will only contain
# the linear (ignoring p2) "mainbranch". since linelog cannot move
# backwards without a rebuild, this should be something that always moves
# forward, usually it is "master" or "@".
mainbranch = master
# fastannotate supports different modes to expose its feature.
# a list of combination:
# - fastannotate: expose the feature via the "fastannotate" command which
# deals with everything in a most efficient way, and provides extra
# features like --deleted etc.
# - fctx: replace fctx.annotate implementation. note:
# a. it is less efficient than the "fastannotate" command
# b. it will make it practically impossible to access the old (disk
# side-effect free) annotate implementation
# c. it implies "hgweb".
# - hgweb: replace hgweb's annotate implementation. conflict with "fctx".
# (default: fastannotate)
modes = fastannotate
# default format when no format flags are used (default: number)
defaultformat = changeset, user, date
# serve the annotate cache via wire protocol (default: False)
# tip: the .hg/fastannotate directory is portable - can be rsynced
server = True
# build annotate cache on demand for every client request (default: True)
# disabling it could make server response faster, useful when there is a
# cronjob building the cache.
serverbuildondemand = True
# update local annotate cache from remote on demand
client = False
# path to use when connecting to the remote server (default: default)
remotepath = default
# minimal length of the history of a file required to fetch linelog from
# the server. (default: 10)
clientfetchthreshold = 10
# for "fctx" mode, always follow renames regardless of command line option.
# this is a BC with the original command but will reduced the space needed
# for annotate cache, and is useful for client-server setup since the
# server will only provide annotate cache with default options (i.e. with
# follow). do not affect "fastannotate" mode. (default: True)
forcefollow = True
# for "fctx" mode, always treat file as text files, to skip the "isbinary"
# check. this is consistent with the "fastannotate" command and could help
# to avoid a file fetch if remotefilelog is used. (default: True)
forcetext = True
# use unfiltered repo for better performance.
unfilteredrepo = True
# sacrifice correctness in some corner cases for performance. it does not
# affect the correctness of the annotate cache being built. the option
# is experimental and may disappear in the future (default: False)

Remote repository management
fetch
pull changes from a remote repository, merge new changes if needed.:
hg fetch [SOURCE]
This finds all changes from the repository at the specified path or URL and adds them to the local
repository.
If the pulled changes add a new branch head, the head is automatically merged, and the result of the
merge is committed. Otherwise, the working directory is updated to include the new changes.
When a merge is needed, the working directory is first updated to the newly pulled changes. Local changes
are then merged into the pulled changes. To switch the merge order, use --switch-parent.
See hg help dates for a list of formats valid for -d/--date.
Returns 0 on success.

fix
rewrite file content in changesets or working copy (EXPERIMENTAL)
Provides a command that runs configured tools on the contents of modified files, writing back any fixes
to the working copy or replacing changesets.
Fixer tools are run in the repository's root directory. This allows them to read configuration files from
the working copy, or even write to the working copy. The working copy is not updated to match the
revision being fixed. In fact, several revisions may be fixed in parallel. Writes to the working copy are
not amended into the revision being fixed; fixer tools MUST always read content to be fixed from stdin,
and write fixed file content back to stdout.
Here is an example configuration that causes hg fix to apply automatic formatting fixes to modified lines
in C++ code:
[fix]
clang-format:command=clang-format --assume-filename={rootpath}
clang-format:linerange=--lines={first}:{last}
clang-format:pattern=set:**.cpp or **.hpp
The :command suboption forms the first part of the shell command that will be used to fix a file. The
content of the file is passed on standard input, and the fixed file content is expected on standard
output. Any output on standard error will be displayed as a warning. If the exit status is not zero, the
file will not be affected. A placeholder warning is displayed if there is a non-zero exit status but no
standard error output. Some values may be substituted into the command:
{rootpath} The path of the file being fixed, relative to the repo root
{basename} The name of the file being fixed, without the directory path
If the :linerange suboption is set, the tool will only be run if there are changed lines in a file. The
value of this suboption is appended to the shell command once for every range of changed lines in the
file. Some values may be substituted into the command:
{first} The 1-based line number of the first line in the modified range
{last} The 1-based line number of the last line in the modified range
Deleted sections of a file will be ignored by :linerange, because there is no corresponding line range in
the version being fixed.
By default, tools that set :linerange will only be executed if there is at least one changed line range.
This is meant to prevent accidents like running a code formatter in such a way that it unexpectedly
reformats the whole file. If such a tool needs to operate on unchanged files, it should set the
:skipclean suboption to false.
The :pattern suboption determines which files will be passed through each configured tool. See hg help
patterns for possible values. However, all patterns are relative to the repo root, even if that text says
they are relative to the current working directory. If there are file arguments to hg fix, the
intersection of these patterns is used.
There is also a configurable limit for the maximum size of file that will be processed by hg fix:
[fix]
maxfilesize = 2MB
Normally, execution of configured tools will continue after a failure (indicated by a non-zero exit
status). It can also be configured to abort after the first such failure, so that no files will be
affected if any tool fails. This abort will also cause hg fix to exit with a non-zero status:
[fix]
failure = abort
When multiple tools are configured to affect a file, they execute in an order defined by the :priority
suboption. The priority suboption has a default value of zero for each tool. Tools are executed in order
of descending priority. The execution order of tools with equal priority is unspecified. For example, you
could use the 'sort' and 'head' utilities to keep only the 10 smallest numbers in a text file by ensuring
that 'sort' runs before 'head':
[fix]
sort:command = sort -n
head:command = head -n 10
sort:pattern = numbers.txt
head:pattern = numbers.txt
sort:priority = 2
head:priority = 1
To account for changes made by each tool, the line numbers used for incremental formatting are recomputed
before executing the next tool. So, each tool may see different values for the arguments added by the
:linerange suboption.
Each fixer tool is allowed to return some metadata in addition to the fixed file content. The metadata
must be placed before the file content on stdout, separated from the file content by a zero byte. The
metadata is parsed as a JSON value (so, it should be UTF-8 encoded and contain no zero bytes). A fixer
tool is expected to produce this metadata encoding if and only if the :metadata suboption is true:
[fix]
tool:command = tool --prepend-json-metadata
tool:metadata = true
The metadata values are passed to hooks, which can be used to print summaries or perform other
post-fixing work. The supported hooks are:
"postfixfile"
Run once for each file in each revision where any fixer tools made changes
to the file content. Provides "$HG_REV" and "$HG_PATH" to identify the file,
and "$HG_METADATA" with a map of fixer names to metadata values from fixer
tools that affected the file. Fixer tools that didn't affect the file have a
value of None. Only fixer tools that executed are present in the metadata.
"postfix"
Run once after all files and revisions have been handled. Provides
"$HG_REPLACEMENTS" with information about what revisions were created and
made obsolete. Provides a boolean "$HG_WDIRWRITTEN" to indicate whether any
files in the working copy were updated. Provides a list "$HG_METADATA"
mapping fixer tool names to lists of metadata values returned from
executions that modified a file. This aggregates the same metadata
previously passed to the "postfixfile" hook.
Commands
File content management
fix
rewrite file content in changesets or working directory:
hg fix [OPTION]... [FILE]...
Runs any configured tools to fix the content of files. (See hg help -e fix for details about configuring
tools.) Only affects files with changes, unless file arguments are provided. Only affects changed lines
of files, unless the --whole flag is used. Some tools may always affect the whole file regardless of
--whole.
If --working-dir is used, files with uncommitted changes in the working copy will be fixed. Note that no
backup are made.
If revisions are specified with --source, those revisions and their descendants will be checked, and they
may be replaced with new revisions that have fixed file content. By automatically including the
descendants, no merging, rebasing, or evolution will be required. If an ancestor of the working copy is
included, then the working copy itself will also be fixed, and the working copy will be updated to the
fixed parent.
When determining what lines of each file to fix at each revision, the whole set of revisions being fixed
is considered, so that fixes to earlier revisions are not forgotten in later ones. The --base flag can be

fsmonitor
Faster status operations with the Watchman file monitor (EXPERIMENTAL)
Integrates the file-watching program Watchman with Mercurial to produce faster status results.
On a particular Linux system, for a real-world repository with over 400,000 files hosted on ext4, vanilla
hg status takes 1.3 seconds. On the same system, with fsmonitor it takes about 0.3 seconds.
fsmonitor requires no configuration -- it will tell Watchman about your repository as necessary. You'll
need to install Watchman from https://facebook.github.io/watchman/ and make sure it is in your PATH.
fsmonitor is incompatible with the largefiles and eol extensions, and will disable itself if any of those
are active.
The following configuration options exist:
[fsmonitor]
mode = {off, on, paranoid}
When mode = off, fsmonitor will disable itself (similar to not loading the extension at all). When mode =
on, fsmonitor will be enabled (the default). When mode = paranoid, fsmonitor will query both Watchman
and the filesystem, and ensure that the results are consistent.
[fsmonitor]
timeout = (float)
A value, in seconds, that determines how long fsmonitor will wait for Watchman to return results.
Defaults to 2.0.
[fsmonitor]
blacklistusers = (list of userids)
A list of usernames for which fsmonitor will disable itself altogether.
[fsmonitor]
walk_on_invalidate = (boolean)
Whether or not to walk the whole repo ourselves when our cached state has been invalidated, for example
when Watchman has been restarted or .hgignore rules have been changed. Walking the repo in that case can
result in competing for I/O with Watchman. For large repos it is recommended to set this value to false.
You may wish to set this to true if you have a very fast filesystem that can outpace the IPC overhead of
getting the result data for the full repo from Watchman. Defaults to false.
[fsmonitor]
warn_when_unused = (boolean)
Whether to print a warning during certain operations when fsmonitor would be beneficial to performance
but isn't enabled.
[fsmonitor]
warn_update_file_count = (integer)
# or when mercurial is built with rust support
warn_update_file_count_rust = (integer)
If warn_when_unused is set and fsmonitor isn't enabled, a warning will be printed during working
directory updates if this many files will be created.
git
grant Mercurial the ability to operate on Git repositories. (EXPERIMENTAL)
This is currently super experimental. It probably will consume your firstborn a la Rumpelstiltskin, etc.
githelp
try mapping git commands to Mercurial commands
Tries to map a given git command to a Mercurial command:
$ hg githelp -- git checkout master hg update master
If an unknown command or parameter combination is detected, an error is produced.

hgk
browse the repository in a graphical way
The hgk extension allows browsing the history of a repository in a graphical way. It requires Tcl/Tk
version 8.4 or later. (Tcl/Tk is not distributed with Mercurial.)
hgk consists of two parts: a Tcl script that does the displaying and querying of information, and an
extension to Mercurial named hgk.py, which provides hooks for hgk to get information. hgk can be found in
the contrib directory, and the extension is shipped in the hgext repository, and needs to be enabled.
The hg view command will launch the hgk Tcl script. For this command to work, hgk must be in your search
path. Alternately, you can specify the path to hgk in your configuration file:
[hgk]
path = /location/of/hgk
hgk can make use of the extdiff extension to visualize revisions. Assuming you had already configured
extdiff vdiff command, just add:
[hgk]
vdiff=vdiff
Revisions context menu will now display additional entries to fire vdiff on hovered and selected
revisions.
Commands
Change navigation
view
start interactive history viewer:
hg view [-l LIMIT] [REVRANGE]

highlight
syntax highlighting for hgweb (requires Pygments)
It depends on the Pygments syntax highlighting library: http://pygments.org/
There are the following configuration options:
[web]
pygments_style = <style> (default: colorful)
highlightfiles = <fileset> (default: size('<5M'))
highlightonlymatchfilename = <bool> (default False)
highlightonlymatchfilename will only highlight files if their type could be identified by their filename.
When this is not enabled (the default), Pygments will try very hard to identify the file type from
content and any match (even matches with a low confidence score) will be used.
histedit
interactive history editing
With this extension installed, Mercurial gains one new command: histedit. Usage is as follows, assuming
the following history:
@ 3[tip] 7c2fd3b9020c 2009-04-27 18:04 -0500 durin42
| Add delta
|
o 2 030b686bedc4 2009-04-27 18:04 -0500 durin42
| Add gamma
|
o 1 c561b4e977df 2009-04-27 18:04 -0500 durin42
| Add beta
|
o 0 d8d2fcd0e319 2009-04-27 18:04 -0500 durin42
Add alpha
If you were to run hg histedit c561b4e977df, you would see the following file open in your editor:
pick c561b4e977df Add beta
pick 030b686bedc4 Add gamma
pick 7c2fd3b9020c Add delta
# Edit history between c561b4e977df and 7c2fd3b9020c
#
# Commits are listed from least to most recent
#
# Commands:
# p, pick = use commit
# e, edit = use commit, but allow edits before making new commit
# f, fold = use commit, but combine it with the one above
# r, roll = like fold, but discard this commit's description and date
# d, drop = remove commit from history
# m, mess = edit commit message without changing commit content
# b, base = checkout changeset and apply further changesets from there
#
In this file, lines beginning with # are ignored. You must specify a rule for each revision in your
history. For example, if you had meant to add gamma before beta, and then wanted to add delta in the same
revision as beta, you would reorganize the file to look like this:
pick 030b686bedc4 Add gamma
pick c561b4e977df Add beta
fold 7c2fd3b9020c Add delta
# Edit history between c561b4e977df and 7c2fd3b9020c
#
# Commits are listed from least to most recent
#
# Commands:
# p, pick = use commit
# e, edit = use commit, but allow edits before making new commit
# f, fold = use commit, but combine it with the one above
# r, roll = like fold, but discard this commit's description and date
# d, drop = remove commit from history
# m, mess = edit commit message without changing commit content
# b, base = checkout changeset and apply further changesets from there
#
At which point you close the editor and histedit starts working. When you specify a fold operation,
histedit will open an editor when it folds those revisions together, offering you a chance to clean up
the commit message:
Add beta
***
Add delta
Edit the commit message to your liking, then close the editor. The date used for the commit will be the
later of the two commits' dates. For this example, let's assume that the commit message was changed to
Add beta and delta. After histedit has run and had a chance to remove any old or temporary revisions it
needed, the history looks like this:
@ 2[tip] 989b4d060121 2009-04-27 18:04 -0500 durin42
| Add beta and delta.
|
o 1 081603921c3f 2009-04-27 18:04 -0500 durin42
| Add gamma
|
o 0 d8d2fcd0e319 2009-04-27 18:04 -0500 durin42
Add alpha
Note that histedit does not remove any revisions (even its own temporary ones) until after it has
completed all the editing operations, so it will probably perform several strip operations when it's
done. For the above example, it had to run strip twice. Strip can be slow depending on a variety of
factors, so you might need to be a little patient. You can choose to keep the original revisions by
passing the --keep flag.
The edit operation will drop you back to a command prompt, allowing you to edit files freely, or even use
hg record to commit some changes as a separate commit. When you're done, any remaining uncommitted
changes will be committed as well. When done, run hg histedit --continue to finish this step. If there
are uncommitted changes, you'll be prompted for a new commit message, but the default commit message will
be the original message for the edit ed revision, and the date of the original commit will be preserved.
The message operation will give you a chance to revise a commit message without changing the contents.
It's a shortcut for doing edit immediately followed by hg histedit --continue`.
If histedit encounters a conflict when moving a revision (while handling pick or fold), it'll stop in a
similar manner to edit with the difference that it won't prompt you for a commit message when done. If
you decide at this point that you don't like how much work it will be to rearrange history, or that you
made a mistake, you can use hg histedit --abort to abandon the new changes you have made and return to
the state before you attempted to edit your history.
If we clone the histedit-ed example repository above and add four more changes, such that we have the
following history:
@ 6[tip] 038383181893 2009-04-27 18:04 -0500 stefan
| Add theta
|
o 5 140988835471 2009-04-27 18:04 -0500 stefan
| Add eta

|
o 0 d8d2fcd0e319 2009-04-27 18:04 -0500 durin42
Add alpha
If you run hg histedit --outgoing on the clone then it is the same as running hg histedit 836302820282.
If you need plan to push to a repository that Mercurial does not detect to be related to the source repo,
you can add a --force option.
Config
Histedit rule lines are truncated to 80 characters by default. You can customize this behavior by setting
a different length in your configuration file:
[histedit]
linelen = 120 # truncate rule lines at 120 characters
The summary of a change can be customized as well:
[histedit]
summary-template = '{rev} {bookmarks} {desc|firstline}'
The customized summary should be kept short enough that rule lines will fit in the configured line
length. See above if that requires customization.
hg histedit attempts to automatically choose an appropriate base revision to use. To change which base
revision is used, define a revset in your configuration file:
[histedit]
defaultrev = only(.) & draft()
By default each edited revision needs to be present in histedit commands. To remove revision you need to
use drop operation. You can configure the drop to be implicit for missing commits by adding:
[histedit]
dropmissing = True
By default, histedit will close the transaction after each action. For performance purposes, you can
configure histedit to use a single transaction across the entire histedit. WARNING: This setting
introduces a significant risk of losing the work you've done in a histedit if the histedit aborts
unexpectedly:
[histedit]
singletransaction = True
Commands
Change manipulation
histedit
interactively edit changeset history:
hg histedit [OPTIONS] ([ANCESTOR] | --outgoing [URL])
This command lets you edit a linear series of changesets (up to and including the working directory,
which should be clean). You can:
• pick to [re]order a changeset
• drop to omit changeset
• mess to reword the changeset commit message
• fold to combine it with the preceding changeset (using the later date)
• roll like fold, but discarding this commit's description and date
• edit to edit this changeset (preserving date)
• base to checkout changeset and apply further changesets from there
There are a number of ways to select the root changeset:
• Specify ANCESTOR directly
• Use --outgoing -- it will be the first linear changeset not included in destination. (See hg help
config.paths.default-push)
• Otherwise, the value from the "histedit.defaultrev" config option is used as a revset to select the
base revision when ANCESTOR is not specified. The first revision returned by the revset is used. By
default, this selects the editable history that is unique to the ancestry of the working directory.
If you use --outgoing, this command will abort if there are ambiguous outgoing revisions. For example, if
there are multiple branches containing outgoing revisions.
Use "min(outgoing() and ::.)" or similar revset specification instead of --outgoing to specify edit
target revision exactly in such ambiguous situation. See hg help revsets for detail about selecting
revisions.
Examples:
• A number of changes have been made. Revision 3 is no longer needed.
Start history editing from revision 3:
hg histedit -r 3
An editor opens, containing the list of revisions, with specific actions specified:
pick 5339bf82f0ca 3 Zworgle the foobar
pick 8ef592ce7cc4 4 Bedazzle the zerlog
pick 0a9639fcda9d 5 Morgify the cromulancy
Additional information about the possible actions to take appears below the list of revisions.
To remove revision 3 from the history, its action (at the beginning of the relevant line) is changed
to 'drop':
drop 5339bf82f0ca 3 Zworgle the foobar
pick 8ef592ce7cc4 4 Bedazzle the zerlog
pick 0a9639fcda9d 5 Morgify the cromulancy
• A number of changes have been made. Revision 2 and 4 need to be swapped.
Start history editing from revision 2:
hg histedit -r 2
An editor opens, containing the list of revisions, with specific actions specified:
pick 252a1af424ad 2 Blorb a morgwazzle
pick 5339bf82f0ca 3 Zworgle the foobar
pick 8ef592ce7cc4 4 Bedazzle the zerlog
To swap revision 2 and 4, its lines are swapped in the editor:
pick 8ef592ce7cc4 4 Bedazzle the zerlog
pick 5339bf82f0ca 3 Zworgle the foobar
pick 252a1af424ad 2 Blorb a morgwazzle
Returns 0 on success, 1 if user intervention is required (not only for intentional "edit" command, but
also for resolving unexpected conflicts).
Options:
--commands <FILE>

hooklib
collection of simple hooks for common tasks (EXPERIMENTAL)
This extension provides a number of simple hooks to handle issues commonly found in repositories with
many contributors: - email notification when changesets move from draft to public phase - email
notification when changesets are obsoleted - enforcement of draft phase for all incoming changesets -
enforcement of a no-branch-merge policy - enforcement of a no-multiple-heads policy
The implementation of the hooks is subject to change, e.g. whether to implement them as individual hooks
or merge them into the notify extension as option. The functionality itself is planned to be supported
long-term.
journal
track previous positions of bookmarks (EXPERIMENTAL)
This extension adds a new command: hg journal, which shows you where bookmarks were previously located.
Commands
Change organization
journal
show the previous position of bookmarks and the working copy:
hg journal [OPTION]... [BOOKMARKNAME]
The journal is used to see the previous commits that bookmarks and the working copy pointed to. By
default the previous locations for the working copy. Passing a bookmark name will show all the previous
positions of that bookmark. Use the --all switch to show previous locations for all bookmarks and the
working copy; each line will then include the bookmark name, or '.' for the working copy, as well.
If name starts with re:, the remainder of the name is treated as a regular expression. To match a name
that actually starts with re:, use the prefix literal:.
By default hg journal only shows the commit hash and the command that was running at that time.
-v/--verbose will show the prior hash, the user, and the time at which it happened.
Use -c/--commits to output log information on each commit hash; at this point you can use the usual
--patch, --git, --stat and --template switches to alter the log output for these.
hg journal -T json can be used to produce machine readable output.
Options:
--all show history for all names
-c, --commits
show commit metadata
-p, --patch
show patch
-g, --git
use git extended diff format
-l,--limit <NUM>
limit number of changes displayed
--stat output diffstat-style summary of changes
--style <STYLE>
display using template map file (DEPRECATED)
-T,--template <TEMPLATE>
display with template
keyword
expand keywords in tracked files
This extension expands RCS/CVS-like or self-customized $Keywords$ in tracked text files selected by your
configuration.
Keywords are only expanded in local repositories and not stored in the change history. The mechanism can
be regarded as a convenience for the current user or for archive distribution.
Keywords expand to the changeset data pertaining to the latest change relative to the working directory
parent of each file.
Configuration is done in the [keyword], [keywordset] and [keywordmaps] sections of hgrc files.
Example:
[keyword]
# expand keywords in every python file except those matching "x*"
**.py =
x* = ignore
[keywordset]
# prefer svn- over cvs-like default keywordmaps
svn = True
Note The more specific you are in your filename patterns the less you lose speed in huge repositories.
For [keywordmaps] template mapping and expansion demonstration and control run hg kwdemo. See hg help
templates for a list of available templates and filters.
Three additional date template filters are provided:
utcdate
"2006/09/18 15:13:13"
svnutcdate
"2006-09-18 15:13:13Z"
svnisodate
"2006-09-18 08:13:13 -700 (Mon, 18 Sep 2006)"
The default template mappings (view with hg kwdemo -d) can be replaced with customized keywords and
templates. Again, run hg kwdemo to control the results of your configuration changes.
Before changing/disabling active keywords, you must run hg kwshrink to avoid storing expanded keywords in
the change history.
To force expansion after enabling it, or a configuration change, run hg kwexpand.
Expansions spanning more than one line and incremental expansions, like CVS' $Log$, are not supported. A
keyword template map "Log = {desc}" expands to the first line of the changeset description.

are actual candidates for expansion.
See hg help keyword on how to construct patterns both for inclusion and exclusion of files.
With -A/--all and -v/--verbose the codes used to show the status of files are:
K = keyword expansion candidate
k = keyword expansion candidate (not tracked)
I = ignored
i = ignored (not tracked)
Options:
-A, --all
show keyword status flags of all files
-i, --ignore
show files excluded from expansion

largefiles
track large binary files
Large binary files tend to be not very compressible, not very diffable, and not at all mergeable. Such
files are not handled efficiently by Mercurial's storage format (revlog), which is based on compressed
binary deltas; storing large binary files as regular Mercurial files wastes bandwidth and disk space and
increases Mercurial's memory usage. The largefiles extension addresses these problems by adding a
centralized client-server layer on top of Mercurial: largefiles live in a central store out on the
network somewhere, and you only fetch the revisions that you need when you need them.
largefiles works by maintaining a "standin file" in .hglf/ for each largefile. The standins are small (41
bytes: an SHA-1 hash plus newline) and are tracked by Mercurial. Largefile revisions are identified by
the SHA-1 hash of their contents, which is written to the standin. largefiles uses that revision ID to
get/put largefile revisions from/to the central store. This saves both disk space and bandwidth, since
you don't need to retrieve all historical revisions of large files when you clone or pull.
To start a new repository or add new large binary files, just add --large to your hg add command. For
example:
$ dd if=/dev/urandom of=randomdata count=2000
$ hg add --large randomdata
$ hg commit -m "add randomdata as a largefile"
When you push a changeset that adds/modifies largefiles to a remote repository, its largefile revisions
will be uploaded along with it. Note that the remote Mercurial must also have the largefiles extension
enabled for this to work.
When you pull a changeset that affects largefiles from a remote repository, the largefiles for the
changeset will by default not be pulled down. However, when you update to such a revision, any largefiles
needed by that revision are downloaded and cached (if they have never been downloaded before). One way to
pull largefiles when pulling is thus to use --update, which will update your working copy to the latest
pulled revision (and thereby downloading any new largefiles).
If you want to pull largefiles you don't need for update yet, then you can use pull with the --lfrev
option or the hg lfpull command.
If you know you are pulling from a non-default location and want to download all the largefiles that
correspond to the new changesets at the same time, then you can pull with --lfrev "pulled()".
If you just want to ensure that you will have the largefiles needed to merge or rebase with new heads
that you are pulling, then you can pull with --lfrev "head(pulled())" flag to pre-emptively download any
largefiles that are new in the heads you are pulling.
Keep in mind that network access may now be required to update to changesets that you have not previously
updated to. The nature of the largefiles extension means that updating is no longer guaranteed to be a
local-only operation.
If you already have large files tracked by Mercurial without the largefiles extension, you will need to
convert your repository in order to benefit from largefiles. This is done with the hg lfconvert command:
$ hg lfconvert --size 10 oldrepo newrepo
In repositories that already have largefiles in them, any new file over 10MB will automatically be added
as a largefile. To change this threshold, set largefiles.minsize in your Mercurial config file to the
minimum size in megabytes to track as a largefile, or use the --lfsize option to the add command (also in
megabytes):
[largefiles]
minsize = 2
$ hg add --lfsize 2
The largefiles.patterns config option allows you to specify a list of filename patterns (see hg help
patterns) that should always be tracked as largefiles:
[largefiles]
patterns =
*.jpg
re:.*\.(png|bmp)$
library.zip
content/audio/*
Files that match one of these patterns will be added as largefiles regardless of their size.
The largefiles.minsize and largefiles.patterns config options will be ignored for any repositories not
already containing a largefile. To add the first largefile to a repository, you must explicitly do so
with the --large flag passed to the hg add command.

Convert repository SOURCE to a new repository DEST, identical to SOURCE except that certain files will be
converted as largefiles: specifically, any file that matches any PATTERN or whose size is above the
minimum size threshold is converted as a largefile. The size used to determine whether or not to track a
file as a largefile is the size of the first version of the file. The minimum size can be specified
either with --size or in configuration as largefiles.size.
After running this command you will need to make sure that largefiles is enabled anywhere you intend to
push the new repository.
Use --to-normal to convert largefiles back to normal files; after this, the DEST repository can be used
without largefiles at all.
Options:
-s,--size <SIZE>
minimum size (MB) for files to be converted as largefiles
--to-normal
convert from a largefiles repo to a normal repo
lfpull
pull largefiles for the specified revisions from the specified source:
hg lfpull -r REV... [-e CMD] [--remotecmd CMD] [SOURCE]
Pull largefiles that are referenced from local changesets but missing locally, pulling from a remote
repository to the local cache.
If SOURCE is omitted, the 'default' path will be used. See hg help urls for more information.
Some examples:
• pull largefiles for all branch heads:
hg lfpull -r "head() and not closed()"
• pull largefiles on the default branch:
hg lfpull -r "branch(default)"
Options:
-r,--rev <VALUE[+]>
pull largefiles for these revisions
-e,--ssh <CMD>
specify ssh command to use
--remotecmd <CMD>
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
[+] marked option can be specified multiple times
lfs
lfs - large file support (EXPERIMENTAL)
This extension allows large files to be tracked outside of the normal repository storage and stored on a
centralized server, similar to the largefiles extension. The git-lfs protocol is used when communicating
with the server, so existing git infrastructure can be harnessed. Even though the files are stored
outside of the repository, they are still integrity checked in the same manner as normal files.
The files stored outside of the repository are downloaded on demand, which reduces the time to clone, and
possibly the local disk usage. This changes fundamental workflows in a DVCS, so careful thought should
be given before deploying it. hg convert can be used to convert LFS repositories to normal repositories
that no longer require this extension, and do so without changing the commit hashes. This allows the
extension to be disabled if the centralized workflow becomes burdensome. However, the pre and post
convert clones will not be able to communicate with each other unless the extension is enabled on both.
To start a new repository, or to add LFS files to an existing one, just create an .hglfs file as
described below in the root directory of the repository. Typically, this file should be put under
version control, so that the settings will propagate to other repositories with push and pull. During
any commit, Mercurial will consult this file to determine if an added or modified file should be stored
externally. The type of storage depends on the characteristics of the file at each commit. A file that
is near a size threshold may switch back and forth between LFS and normal storage, as needed.
Alternately, both normal repositories and largefile controlled repositories can be converted to LFS by
using hg convert and the lfs.track config option described below. The .hglfs file should then be created
and added, to control subsequent LFS selection. The hashes are also unchanged in this case. The LFS and
non-LFS repositories can be distinguished because the LFS repository will abort any command if this
extension is disabled.
Committed LFS files are held locally, until the repository is pushed. Prior to pushing the normal
repository data, the LFS files that are tracked by the outgoing commits are automatically uploaded to the
configured central server. No LFS files are transferred on hg pull or hg clone. Instead, the files are
downloaded on demand as they need to be read, if a cached copy cannot be found locally. Both committing
and downloading an LFS file will link the file to a usercache, to speed up future access. See the
usercache config setting described below.
The extension reads its configuration from a versioned .hglfs configuration file found in the root of the
working directory. The .hglfs file uses the same syntax as all other Mercurial configuration files. It
uses a single section, [track].
The [track] section specifies which files are stored as LFS (or not). Each line is keyed by a file
pattern, with a predicate value. The first file pattern match is used, so put more specific patterns
first. The available predicates are all(), none(), and size(). See "hg help filesets.size" for the
latter.
Example versioned .hglfs file:
[track]
# No Makefile or python file, anywhere, will be LFS
**Makefile = none()
**.py = none()
**.zip = all()
**.exe = size(">1MB")
# Catchall for everything not matched above
** = size(">10MB")
Configs:
[lfs]
# Remote endpoint. Multiple protocols are supported:
# - http(s)://user:pass@example.com/path
# git-lfs endpoint
# - file:///tmp/path
# local filesystem, usually for testing
# if unset, lfs will assume the remote repository also handles blob storage
# for http(s) URLs. Otherwise, lfs will prompt to set this when it must
# use this value.
# (default: unset)
url = https://example.com/repo.git/info/lfs
# Which files to track in LFS. Path tests are "**.extname" for file
# extensions, and "path:under/some/directory" for path prefix. Both
# are relative to the repository root.
# File size can be tested with the "size()" fileset, and tests can be
# joined with fileset operators. (See "hg help filesets.operators".)
#
# Some examples:
# - all() # everything
# - none() # nothing
# - size(">20MB") # larger than 20MB
# - !**.txt # anything not a *.txt file
# - **.zip | **.tar.gz | **.7z # some types of compressed files
# - path:bin # files under "bin" in the project root
# - (**.php & size(">2MB")) | (**.js & size(">5MB")) | **.tar.gz
# | (path:bin & !path:/bin/README) | size(">1GB")
# (default: none())
#
# This is ignored if there is a tracked '.hglfs' file, and this setting
# will eventually be deprecated and removed.
track = size(">10M")
# how many times to retry before giving up on transferring an object
retry = 5
# the local directory to store lfs files for sharing across local clones.
# If not set, the cache is located in an OS specific cache location.

Commands
Uncategorized commands
logtoprocess
send ui.log() data to a subprocess (EXPERIMENTAL)
This extension lets you specify a shell command per ui.log() event, sending all remaining arguments to as
environment variables to that command.
Positional arguments construct a log message, which is passed in the MSG1 environment variables. Each
keyword argument is set as a OPT_UPPERCASE_KEY variable (so the key is uppercased, and prefixed with
OPT_). The original event name is passed in the EVENT environment variable, and the process ID of
mercurial is given in HGPID.
So given a call ui.log('foo', 'bar %s ', 'baz', spam='eggs'), a script configured for the `foo event can
expect an environment with MSG1=bar baz, and OPT_SPAM=eggs.
Scripts are configured in the [logtoprocess] section, each key an event name. For example:
[logtoprocess]
commandexception = echo "$MSG1" > /var/log/mercurial_exceptions.log
would log the warning message and traceback of any failed command dispatch.
Scripts are run asynchronously as detached daemon processes; mercurial will not ensure that they exit
cleanly.
mq
manage a stack of patches
This extension lets you work with a stack of patches in a Mercurial repository. It manages two stacks of
patches - all known patches, and applied patches (subset of known patches).
Known patches are represented as patch files in the .hg/patches directory. Applied patches are both patch
files and changesets.
Common tasks (use hg help COMMAND for more details):
create new patch qnew
import existing patch qimport
print patch series qseries
print applied patches qapplied
add known patch to applied stack qpush
remove patch from applied stack qpop
refresh contents of top applied patch qrefresh
By default, mq will automatically use git patches when required to avoid losing file mode changes, copy
records, binary files or empty files creations or deletions. This behavior can be configured with:
[mq]
git = auto/keep/yes/no
If set to 'keep', mq will obey the [diff] section configuration while preserving existing git patches
upon qrefresh. If set to 'yes' or 'no', mq will override the [diff] section and always generate git or
regular patches, possibly losing data in the second case.
It may be desirable for mq changesets to be kept in the secret phase (see hg help phases), which can be
enabled with the following setting:
[mq]
secret = True
You will by default be managing a patch queue named "patches". You can create other, independent patch
queues with the hg qqueue command.
If the working directory contains uncommitted files, qpush, qpop and qgoto abort immediately. If
-f/--force is used, the changes are discarded. Setting:
[mq]
keepchanges = True
make them behave as if --keep-changes were passed, and non-conflicting local changes will be tolerated
and preserved. If incompatible options such as -f/--force or --exact are passed, this setting is ignored.
This extension used to provide a strip command. This command now lives in the strip extension.
Commands
Repository creation
qclone
clone main and patch repository at same time:
hg qclone [OPTION]... SOURCE [DEST]
If source is local, destination will have no patches applied. If source is remote, this command can not
check if patches are applied in source, so cannot guarantee that patches are not applied in destination.
If you clone remote repository, be sure before that it has no patches applied.
Source patch repository is looked for in <src>/.hg/patches by default. Use -p <url> to change.
The patch directory must be a nested Mercurial repository, as would be created by hg init --mq.
Return 0 on success.
Options:
--pull use pull protocol to copy metadata
-U, --noupdate
do not update the new working directories
--uncompressed
use uncompressed transfer (fast over LAN)
-p,--patches <REPO>
location of source patch repository
-e,--ssh <CMD>
specify ssh command to use
--remotecmd <CMD>
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
qinit
init a new queue repository (DEPRECATED):
hg qinit [-c]
The queue repository is unversioned by default. If -c/--create-repo is specified, qinit will create a
separate nested repository for patches (qinit -c may also be run later to convert an unversioned patch
repository into a versioned one). You can use qcommit to commit changes to this queue repository.
This command is deprecated. Without -c, it's implied by other relevant commands. With -c, use hg init
--mq instead.
Options:
-c, --create-repo
create queue repository
Change creation
qcommit
commit changes in the queue repository (DEPRECATED):
hg qcommit [OPTION]... [FILE]...
This command is deprecated; use hg commit --mq instead.
Options:
-A, --addremove
mark new/missing files as added/removed before committing
--close-branch
mark a branch head as closed
--amend
amend the parent of the working directory
-s, --secret

[+] marked option can be specified multiple times
aliases: qci
qnew
create a new patch:
hg qnew [-e] [-m TEXT] [-l FILE] PATCH [FILE]...
qnew creates a new patch on top of the currently-applied patch (if any). The patch will be initialized
with any outstanding changes in the working directory. You may also use -I/--include, -X/--exclude,
and/or a list of files after the patch name to add only changes to matching files to the new patch,
leaving the rest as uncommitted modifications.
-u/--user and -d/--date can be used to set the (given) user and date, respectively. -U/--currentuser and
-D/--currentdate set user to current user and date to current date.
-e/--edit, -m/--message or -l/--logfile set the patch header as well as the commit message. If none is
specified, the header is empty and the commit message is '[mq]: PATCH'.
Use the -g/--git option to keep the patch in the git extended diff format. Read the diffs help topic for
more information on why this is important for preserving permission changes and copy/rename information.
Returns 0 on successful creation of a new patch.
Options:
-e, --edit
invoke editor on commit messages
-f, --force
import uncommitted changes (DEPRECATED)
-g, --git
use git extended diff format
-U, --currentuser

read commit message from file
[+] marked option can be specified multiple times
qrefresh
update the current patch:
hg qrefresh [-I] [-X] [-e] [-m TEXT] [-l FILE] [-s] [FILE]...
If any file patterns are provided, the refreshed patch will contain only the modifications that match
those patterns; the remaining modifications will remain in the working directory.
If -s/--short is specified, files currently included in the patch will be refreshed just like matched
files and remain in the patch.
If -e/--edit is specified, Mercurial will start your configured editor for you to enter a message. In
case qrefresh fails, you will find a backup of your message in .hg/last-message.txt.
hg add/remove/copy/rename work as usual, though you might want to use git-style patches (-g/--git or
[diff] git=1) to track copies and renames. See the diffs help topic for more information on the git diff
format.
Returns 0 on success.
Options:
-e, --edit
invoke editor on commit messages
-g, --git
use git extended diff format
-s, --short
refresh only files already in the patch and specified files
-U, --currentuser
add/update author field in patch with current user

Change manipulation
qfold
fold the named patches into the current patch:
hg qfold [-e] [-k] [-m TEXT] [-l FILE] PATCH...
Patches must not yet be applied. Each patch will be successively applied to the current patch in the
order given. If all the patches apply successfully, the current patch will be refreshed with the new
cumulative patch, and the folded patches will be deleted. With -k/--keep, the folded patch files will not
be removed afterwards.
The header for each folded patch will be concatenated with the current patch header, separated by a line
of * * *.
Returns 0 on success.
Options:
-e, --edit
invoke editor on commit messages
-k, --keep
keep folded patch files
-m,--message <TEXT>
use text as commit message
-l,--logfile <FILE>
read commit message from file
Change organization
qapplied
print the patches already applied:
hg qapplied [-1] [-s] [PATCH]
Returns 0 on success.
Options:
-1, --last
show only the preceding applied patch
-s, --summary
print first line of patch header
qdelete
remove patches from queue:
hg qdelete [-k] [PATCH]...
The patches must not be applied, and at least one patch is required. Exact patch identifiers must be
given. With -k/--keep, the patch files are preserved in the patch directory.
To stop managing a patch and move it into permanent history, use the hg qfinish command.
Options:
-k, --keep
keep patch file
-r,--rev <REV[+]>
stop managing a revision (DEPRECATED)
[+] marked option can be specified multiple times
aliases: qremove qrm
qfinish
move applied patches into repository history:
hg qfinish [-a] [REV]...
Finishes the specified revisions (corresponding to applied patches) by moving them out of mq control into
regular repository history.
Accepts a revision range or the -a/--applied option. If --applied is specified, all applied mq revisions
are removed from mq control. Otherwise, the given revisions must be at the base of the stack of applied
patches.
This can be especially useful if your changes have been applied to an upstream repository, or if you are
about to push your changes to upstream.
Returns 0 on success.
Options:
-a, --applied
finish all applied changesets
qgoto
push or pop patches until named patch is at top of stack:
hg qgoto [OPTION]... PATCH
Returns 0 on success.
Options:
--keep-changes
tolerate non-conflicting local changes
-f, --force
overwrite any local changes
--no-backup
do not save backup copies of files
qguard
set or print guards for a patch:
hg qguard [-l] [-n] [PATCH] [-- [+GUARD]... [-GUARD]...]
Guards control whether a patch can be pushed. A patch with no guards is always pushed. A patch with a
positive guard ("+foo") is pushed only if the hg qselect command has activated it. A patch with a
negative guard ("-foo") is never pushed if the hg qselect command has activated it.
With no arguments, print the currently active guards. With arguments, set guards for the named patch.
Note Specifying negative guards now requires '--'.
To set guards on another patch:
hg qguard other.patch -- +2.6.17 -stable
Returns 0 on success.
Options:
-l, --list
list all patches and guards
-n, --none
drop all guards
qheader
print the header of the topmost or specified patch:
hg qheader [PATCH]
Returns 0 on success.
qnext
print the name of the next pushable patch:
hg qnext [-s]
Returns 0 on success.
Options:
-s, --summary
print first line of patch header
qpop
pop the current patch off the stack:
hg qpop [-a] [-f] [PATCH | INDEX]
Without argument, pops off the top of the patch stack. If given a patch name, keeps popping off patches
until the named patch is at the top of the stack.
By default, abort if the working directory contains uncommitted changes. With --keep-changes, abort only
if the uncommitted files overlap with patched files. With -f/--force, backup and discard changes made to
such files.
Return 0 on success.
Options:
-a, --all
pop all patches
-n,--name <NAME>
queue name to pop (DEPRECATED)
--keep-changes
tolerate non-conflicting local changes
-f, --force
forget any local changes to patched files
--no-backup
do not save backup copies of files
qprev
print the name of the preceding applied patch:
hg qprev [-s]
Returns 0 on success.
Options:
-s, --summary
print first line of patch header
qpush
push the next patch onto the stack:
hg qpush [-f] [-l] [-a] [--move] [PATCH | INDEX]
By default, abort if the working directory contains uncommitted changes. With --keep-changes, abort only
if the uncommitted files overlap with patched files. With -f/--force, backup and patch over uncommitted
changes.
Return 0 on success.
Options:
--keep-changes
tolerate non-conflicting local changes
-f, --force
apply on top of local changes
-e, --exact
apply the target patch to its recorded parent
-l, --list
list patch name in commit text
-a, --all
apply all patches
-m, --merge
merge from another queue (DEPRECATED)
-n,--name <NAME>
merge queue name (DEPRECATED)
--move reorder patch series and apply only the patch
--no-backup
do not save backup copies of files
qqueue
manage multiple patch queues:
hg qqueue [OPTION] [QUEUE]
Supports switching between different patch queues, as well as creating new patch queues and deleting
existing ones.
Omitting a queue name or specifying -l/--list will show you the registered queues - by default the
"normal" patches queue is registered. The currently active queue will be marked with "(active)".
Specifying --active will print only the name of the active queue.
To create a new queue, use -c/--create. The queue is automatically made active, except in the case where
there are applied patches from the currently active queue in the repository. Then the queue will only be
created and switching will fail.
To delete an existing queue, use --delete. You cannot delete the currently active queue.
Returns 0 on success.
Options:
-l, --list
list all available queues
--active
print name of active queue
-c, --create
create new queue
--rename
rename active queue
--delete
delete reference to queue
--purge
delete queue, and remove patch dir
qrename
rename a patch:
hg qrename PATCH1 [PATCH2]
With one argument, renames the current patch to PATCH1. With two arguments, renames PATCH1 to PATCH2.
Returns 0 on success.
aliases: qmv
qrestore
restore the queue state saved by a revision (DEPRECATED):
hg qrestore [-d] [-u] REV
This command is deprecated, use hg rebase instead.
Options:
-d, --delete
delete save entry
-u, --update
update queue working directory
qsave
save current queue state (DEPRECATED):
hg qsave [-m TEXT] [-l FILE] [-c] [-n NAME] [-e] [-f]
This command is deprecated, use hg rebase instead.
Options:
-c, --copy
copy patch directory
-n,--name <NAME>
copy directory name
-e, --empty
clear queue status file
-f, --force
force copy
-m,--message <TEXT>
use text as commit message
-l,--logfile <FILE>
read commit message from file
qselect
set or print guarded patches to push:
hg qselect [OPTION]... [GUARD]...
Use the hg qguard command to set or print guards on patch, then use qselect to tell mq which guards to
use. A patch will be pushed if it has no guards or any positive guards match the currently selected
guard, but will not be pushed if any negative guards match the current guard. For example:
qguard foo.patch -- -stable (negative guard)
qguard bar.patch +stable (positive guard)
qselect stable
This activates the "stable" guard. mq will skip foo.patch (because it has a negative match) but push
bar.patch (because it has a positive match).
With no arguments, prints the currently active guards. With one argument, sets the active guard.
Use -n/--none to deactivate guards (no other arguments needed). When no guards are active, patches with
positive guards are skipped and patches with negative guards are pushed.
qselect can change the guards on applied patches. It does not pop guarded patches by default. Use --pop
to pop back to the last applied patch that is not guarded. Use --reapply (which implies --pop) to push
back to the current patch afterwards, but skip guarded patches.
Use -s/--series to print a list of all guards in the series file (no other arguments needed). Use -v for
more information.
Returns 0 on success.
Options:
-n, --none
disable all guards
-s, --series
list all guards in series file
--pop pop to before first guarded applied patch
--reapply
pop, then reapply patches
qseries
print the entire series file:
hg qseries [-ms]
Returns 0 on success.
Options:
-m, --missing
print patches not in series
-s, --summary
print first line of patch header
qtop
print the name of the current patch:
hg qtop [-s]
Returns 0 on success.
Options:
-s, --summary
print first line of patch header
qunapplied
print the patches not yet applied:
hg qunapplied [-1] [-s] [PATCH]
Returns 0 on success.
Options:
-1, --first
show only the first patch
-s, --summary
print first line of patch header
File content management
qdiff
diff of the current patch and subsequent modifications:
hg qdiff [OPTION]... [FILE]...
Shows a diff which includes the current patch as well as any changes which have been made in the working
directory since the last refresh (thus showing what the current patch would become after a qrefresh).
Use hg diff if you only want to see the changes made since the last qrefresh, or hg export qtip if you
want to see changes made by the current patch without including changes made since the qrefresh.
Returns 0 on success.
Options:
-a, --text
treat all files as text
-g, --git
use git extended diff format (DEFAULT: diff.git)
--binary
generate binary diffs in git mode (default)
--nodates
omit dates from diff headers
--noprefix
omit a/ and b/ prefixes from filenames
-p, --show-function
show which function each change is in (DEFAULT: diff.showfunc)
--reverse
produce a diff that undoes the changes
-w, --ignore-all-space
ignore white space when comparing lines
-b, --ignore-space-change
ignore changes in the amount of white space
-B, --ignore-blank-lines
ignore changes whose lines are all blank
-Z, --ignore-space-at-eol

--stat output diffstat-style summary of changes
--root <DIR>
produce diffs relative to subdirectory
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>

[+] marked option can be specified multiple times
Change import/export
qimport
import a patch or existing changeset:
hg qimport [-e] [-n NAME] [-f] [-g] [-P] [-r REV]... [FILE]...
The patch is inserted into the series after the last applied patch. If no patches have been applied,
qimport prepends the patch to the series.
The patch will have the same name as its source file unless you give it a new one with -n/--name.
You can register an existing patch inside the patch directory with the -e/--existing flag.
With -f/--force, an existing patch of the same name will be overwritten.
An existing changeset may be placed under mq control with -r/--rev (e.g. qimport --rev . -n patch will
place the current revision under mq control). With -g/--git, patches imported with --rev will use the git
diff format. See the diffs help topic for information on why this is important for preserving rename/copy
information and permission changes. Use hg qfinish to remove changesets from mq control.
To import a patch from standard input, pass - as the patch file. When importing from standard input, a
patch name must be specified using the --name flag.
To import an existing patch while renaming it:
hg qimport -e existing-patch -n new-name
Returns 0 if import succeeded.
Options:
-e, --existing
import file in patch directory
-n,--name <NAME>
name of patch file
-f, --force
overwrite existing files
-r,--rev <REV[+]>
place existing revisions under mq control
-g, --git
use git extended diff format
-P, --push
qpush after importing
[+] marked option can be specified multiple times
narrow
create clones which fetch history data for subset of files (EXPERIMENTAL)
Commands
Repository maintenance
tracked
show or change the current narrowspec:
hg tracked [OPTIONS]... [REMOTE]
With no argument, shows the current narrowspec entries, one per line. Each line will be prefixed with 'I'
or 'X' for included or excluded patterns, respectively.
The narrowspec is comprised of expressions to match remote files and/or directories that should be pulled
into your client. The narrowspec has include and exclude expressions, with excludes always trumping
includes: that is, if a file matches an exclude expression, it will be excluded even if it also matches
an include expression. Excluding files that were never included has no effect.
Each included or excluded entry is in the format described by 'hg help patterns'.
The options allow you to add or remove included and excluded expressions.
If --clear is specified, then all previous includes and excludes are DROPPED and replaced by the new ones
specified to --addinclude and --addexclude. If --clear is specified without any further options, the
narrowspec will be empty and will not match any files.
If --auto-remove-includes is specified, then those includes that don't match any files modified by
currently visible local commits (those not shared by the remote) will be added to the set of explicitly
specified includes to remove.
--import-rules accepts a path to a file containing rules, allowing you to add --addinclude, --addexclude
rules in bulk. Like the other include and exclude switches, the changes are applied immediately.
Options:
--addinclude <VALUE[+]>
new paths to include
--removeinclude <VALUE[+]>
old paths to no longer include
--auto-remove-includes
automatically choose unused includes to remove
--addexclude <VALUE[+]>
new paths to exclude
--import-rules <VALUE>
import narrowspecs from a file
--removeexclude <VALUE[+]>
old paths to no longer exclude
--clear
whether to replace the existing narrowspec
--force-delete-local-changes
forces deletion of local changes when narrowing
--backup
back up local changes when narrowing (default: True)
--update-working-copy
update working copy when the store has changed
-e,--ssh <CMD>
specify ssh command to use
--remotecmd <CMD>

notify
hooks for sending email push notifications
This extension implements hooks to send email notifications when changesets are sent from or received by
the local repository.
First, enable the extension as explained in hg help extensions, and register the hook you want to run.
incoming and changegroup hooks are run when changesets are received, while outgoing hooks are for
changesets sent to another repository:
[hooks]
# one email for each incoming changeset
incoming.notify = python:hgext.notify.hook
# one email for all incoming changesets
changegroup.notify = python:hgext.notify.hook
# one email for all outgoing changesets
outgoing.notify = python:hgext.notify.hook
This registers the hooks. To enable notification, subscribers must be assigned to repositories. The
[usersubs] section maps multiple repositories to a given recipient. The [reposubs] section maps multiple
recipients to a single repository:
[usersubs]
# key is subscriber email, value is a comma-separated list of repo patterns
user@host = pattern
[reposubs]
# key is repo pattern, value is a comma-separated list of subscriber emails
pattern = user@host
A pattern is a glob matching the absolute path to a repository, optionally combined with a revset
expression. A revset expression, if present, is separated from the glob by a hash. Example:
[reposubs]
*/widgets#branch(release) = qa-team@example.com
This sends to qa-team@example.com whenever a changeset on the release branch triggers a notification in
any repository ending in widgets.
In order to place them under direct user management, [usersubs] and [reposubs] sections may be placed in
a separate hgrc file and incorporated by reference:
[notify]
config = /path/to/subscriptionsfile
Notifications will not be sent until the notify.test value is set to False; see below.
Notifications content can be tweaked with the following configuration entries:
notify.test
If True, print messages to stdout instead of sending them. Default: True.
notify.sources
Space-separated list of change sources. Notifications are activated only when a changeset's source
is in this list. Sources may be:
serve
changesets received via http or ssh
pull
changesets received via hg pull
unbundle
changesets received via hg unbundle
push
changesets sent or received via hg push
bundle
changesets sent via hg unbundle
Default: serve.
notify.strip
Number of leading slashes to strip from url paths. By default, notifications reference
repositories with their absolute path. notify.strip lets you turn them into relative paths. For
example, notify.strip=3 will change /long/path/repository into repository. Default: 0.
notify.domain
Default email domain for sender or recipients with no explicit domain. It is also used for the
domain part of the Message-Id when using notify.messageidseed.
notify.messageidseed
Create deterministic Message-Id headers for the mails based on the seed and the revision
identifier of the first commit in the changeset.
notify.style
Style file to use when formatting emails.
notify.template
Template to use when formatting emails.
notify.incoming
Template to use when run as an incoming hook, overriding notify.template.
notify.outgoing
Template to use when run as an outgoing hook, overriding notify.template.
notify.changegroup
Template to use when running as a changegroup hook, overriding notify.template.
notify.maxdiff
Maximum number of diff lines to include in notification email. Set to 0 to disable the diff, or -1
to include all of it. Default: 300.
notify.maxdiffstat
Maximum number of diffstat lines to include in notification email. Set to -1 to include all of it.
Default: -1.
notify.maxsubject
Maximum number of characters in email's subject line. Default: 67.
notify.diffstat
Set to True to include a diffstat before diff content. Default: True.
notify.showfunc
If set, override diff.showfunc for the diff content. Default: None.
notify.merge
If True, send notifications for merge changesets. Default: True.
notify.mbox
If set, append mails to this mbox file instead of sending. Default: None.
notify.fromauthor
If set, use the committer of the first changeset in a changegroup for the "From" field of the
notification mail. If not set, take the user from the pushing repo. Default: False.
notify.reply-to-predecessor (EXPERIMENTAL)
If set and the changeset has a predecessor in the repository, try to thread the notification mail
with the predecessor. This adds the "In-Reply-To" header to the notification mail with a reference
to the predecessor with the smallest revision number. Mail threads can still be torn, especially
when changesets are folded.
This option must be used in combination with notify.messageidseed.
If set, the following entries will also be used to customize the notifications:
email.from
Email From address to use if none can be found in the generated email content.
web.baseurl
Root repository URL to combine with repository paths when making references. See also
notify.strip.
pager
browse command output with an external pager (DEPRECATED)
Forcibly enable paging for individual commands that don't typically request pagination with the
attend-<command> option. This setting takes precedence over ignore options and defaults:
[pager]
attend-cat = false
patchbomb
command to send changesets as (a series of) patch emails
The series is started off with a "[PATCH 0 of N]" introduction, which describes the series as a whole.
Each patch email has a Subject line of "[PATCH M of N] ...", using the first line of the changeset
description as the subject text. The message contains two or three body parts:
• The changeset description.
• [Optional] The result of running diffstat on the patch.
• The patch itself, as generated by hg export.
Each message refers to the first in the series using the In-Reply-To and References headers, so they will
show up as a sequence in threaded mail and news readers, and in mail archives.
To configure other defaults, add a section like this to your configuration file:
[email]
from = My Name <my@email>
to = recipient1, recipient2, ...
cc = cc1, cc2, ...
bcc = bcc1, bcc2, ...
reply-to = address1, address2, ...
Use [patchbomb] as configuration section name if you need to override global [email] address settings.
Then you can use the hg email command to mail a series of changesets as a patchbomb.
You can also either configure the method option in the email section to be a sendmail compatible mailer
or fill out the [smtp] section so that the patchbomb extension can automatically send patchbombs directly
from the commandline. See the [email] and [smtp] sections in hgrc(5) for details.
By default, hg email will prompt for a To or CC header if you do not supply one via configuration or the
command line. You can override this to never prompt by configuring an empty value:
[email]
cc =
You can control the default inclusion of an introduction message with the patchbomb.intro configuration
option. The configuration is always overwritten by command line flags like --intro and --desc:
[patchbomb]
intro=auto # include introduction message if more than 1 patch (default)
intro=never # never include an introduction message
intro=always # always include an introduction message
You can specify a template for flags to be added in subject prefixes. Flags specified by --flag option
are exported as {flags} keyword:
[patchbomb]
flagtemplate = "{separate(' ',
ifeq(branch, 'default', '', branch|upper),
flags)}"
You can set patchbomb to always ask for confirmation by setting patchbomb.confirm to true.
Commands
Change import/export
email
send changesets by email:
hg email [OPTION]... [DEST]...
By default, diffs are sent in the format generated by hg export, one per message. The series starts with
a "[PATCH 0 of N]" introduction, which describes the series as a whole.
Each patch email has a Subject line of "[PATCH M of N] ...", using the first line of the changeset
description as the subject text. The message contains two or three parts. First, the changeset
description.
With the -d/--diffstat option, if the diffstat program is installed, the result of running diffstat on
the patch is inserted.
Finally, the patch itself, as generated by hg export.
With the -d/--diffstat or --confirm options, you will be presented with a final summary of all messages
and asked for confirmation before the messages are sent.
By default the patch is included as text in the email body for easy reviewing. Using the -a/--attach
option will instead create an attachment for the patch. With -i/--inline an inline attachment will be
created. You can include a patch both as text in the email body and as a regular or an inline attachment
by combining the -a/--attach or -i/--inline with the --body option.
With -B/--bookmark changesets reachable by the given bookmark are selected.
With -o/--outgoing, emails will be generated for patches not found in the destination repository (or only
those which are ancestors of the specified revisions if any are provided)
With -b/--bundle, changesets are selected as for --outgoing, but a single email containing a binary
Mercurial bundle as an attachment will be sent. Use the patchbomb.bundletype config option to control the
bundle type as with hg bundle --type.
With -m/--mbox, instead of previewing each patchbomb message in a pager or sending the messages directly,
it will create a UNIX mailbox file with the patch emails. This mailbox file can be previewed with any
mail user agent which supports UNIX mbox files.
With -n/--test, all steps will run, but mail will not be sent. You will be prompted for an email
recipient address, a subject and an introductory message describing the patches of your patchbomb. Then
when all is done, patchbomb messages are displayed.
In case email sending fails, you will find a backup of your series introductory message in
.hg/last-email.txt.
The default behavior of this command can be customized through configuration. (See hg help patchbomb for
details)
Examples:
hg email -r 3000 # send patch 3000 only
hg email -r 3000 -r 3001 # send patches 3000 and 3001
hg email -r 3000:3005 # send patches 3000 through 3005
hg email 3000 # send patch 3000 (deprecated)
hg email -o # send all patches not in default
hg email -o DEST # send all patches not in DEST
hg email -o -r 3000 # send all ancestors of 3000 not in default
hg email -o -r 3000 DEST # send all ancestors of 3000 not in DEST
hg email -B feature # send all ancestors of feature bookmark
hg email -b # send bundle of all patches not in default
hg email -b DEST # send bundle of all patches not in DEST
hg email -b -r 3000 # bundle of all ancestors of 3000 not in default
hg email -b -r 3000 DEST # bundle of all ancestors of 3000 not in DEST
hg email -o -m mbox && # generate an mbox file...
mutt -R -f mbox # ... and view it with mutt
hg email -o -m mbox && # generate an mbox file ...
formail -s sendmail \ # ... and use formail to send from the mbox
-bm -t < mbox # ... using sendmail
Before using this command, you will need to enable email in your hgrc. See the [email] section in hgrc(5)
for details.

phabricator
simple Phabricator integration (EXPERIMENTAL)
This extension provides a phabsend command which sends a stack of changesets to Phabricator, and a
phabread command which prints a stack of revisions in a format suitable for hg import, and a phabupdate
command to update statuses in batch.
A "phabstatus" view for hg show is also provided; it displays status information of Phabricator
differentials associated with unfinished changesets.
By default, Phabricator requires Test Plan which might prevent some changeset from being sent. The
requirement could be disabled by changing differential.require-test-plan-field config server side.
Config:
[phabricator]
# Phabricator URL
url = https://phab.example.com/
# Repo callsign. If a repo has a URL https://$HOST/diffusion/FOO, then its
# callsign is "FOO".
callsign = FOO
# curl command to use. If not set (default), use builtin HTTP library to
# communicate. If set, use the specified curl command. This could be useful
# if you need to specify advanced options that is not easily supported by
# the internal library.
curlcmd = curl --connect-timeout 2 --retry 3 --silent
# retry failed command N time (default 0). Useful when using the extension
# over flakly connection.
#
# We wait `retry.interval` between each retry, in seconds.
# (default 1 second).
retry = 3
retry.interval = 10
# the retry option can combine well with the http.timeout one.
#
# For example to give up on http request after 20 seconds:
[http]
timeout=20
[auth]
example.schemes = https
example.prefix = phab.example.com
# API token. Get it from https://$HOST/conduit/login/
example.phabtoken = cli-xxxxxxxxxxxxxxxxxxxxxxxxxxxx
Commands
Change import/export
phabimport
import patches from Phabricator for the specified Differential Revisions:
hg phabimport DREVSPEC... [OPTIONS]
The patches are read and applied starting at the parent of the working directory.
See hg help phabread for how to specify DREVSPEC.
Options:
--stack
import dependencies as well
--test-vcr <VALUE>
Path to a vcr file. If nonexistent, will record a new vcr transcript, otherwise will mock all http
requests using the specified vcr file. (ADVANCED)
phabread
print patches from Phabricator suitable for importing:
hg phabread DREVSPEC... [OPTIONS]
DREVSPEC could be a Differential Revision identity, like D123, or just the number 123. It could also have
common operators like +, -, &, (, ) for complex queries. Prefix : could be used to select a stack. If
multiple DREVSPEC values are given, the result is the union of each individually evaluated value. No
attempt is currently made to reorder the values to run from parent to child.
abandoned, accepted, closed, needsreview, needsrevision could be used to filter patches by status. For
performance reason, they only represent a subset of non-status selections and cannot be used alone.
For example, :D6+8-(2+D4) selects a stack up to D6, plus D8 and exclude D2 and D4. :D9 & needsreview
selects "Needs Review" revisions in a stack up to D9.
If --stack is given, follow dependencies information and read all patches. It is equivalent to the :
operator.
Options:
--stack
read dependencies
--test-vcr <VALUE>
Path to a vcr file. If nonexistent, will record a new vcr transcript, otherwise will mock all http
requests using the specified vcr file. (ADVANCED)
phabsend
upload changesets to Phabricator:
hg phabsend REV [OPTIONS]
If there are multiple revisions specified, they will be send as a stack with a linear dependencies
relationship using the order specified by the revset.
For the first time uploading changesets, local tags will be created to maintain the association. After
the first time, phabsend will check obsstore and tags information so it can figure out whether to update
an existing Differential Revision, or create a new one.
If --amend is set, update commit messages so they have the Differential Revision URL, remove related
tags. This is similar to what arcanist will do, and is more desired in author-push workflows. Otherwise,
use local tags to record the Differential Revision association.
The --confirm option lets you confirm changesets before sending them. You can also add following to your
configuration file to make it default behaviour:
[phabsend]
confirm = true
By default, a separate review will be created for each commit that is selected, and will have the same
parent/child relationship in Phabricator. If --fold is set, multiple commits are rolled up into a single
review as if diffed from the parent of the first revision to the last. The commit messages are
concatenated in the summary field on Phabricator.
phabsend will check obsstore and the above association to decide whether to update an existing
Differential Revision, or create a new one.
Options:
-r,--rev <REV[+]>
revisions to send
--amend
update commit messages (default: True)
--reviewer <VALUE[+]>
specify reviewers
--blocker <VALUE[+]>
specify blocking reviewers
-m,--comment <VALUE>
add a comment to Revisions with new/updated Diffs
--confirm
ask for confirmation before sending
--fold combine the revisions into one review
--test-vcr <VALUE>
Path to a vcr file. If nonexistent, will record a new vcr transcript, otherwise will mock all http
requests using the specified vcr file. (ADVANCED)
[+] marked option can be specified multiple times
phabupdate
update Differential Revision in batch:
hg phabupdate [DREVSPEC...| -r REV...] [OPTIONS]
DREVSPEC selects revisions. See hg help phabread for its usage.
Options:
--accept
accept revisions
--reject
reject revisions
--request-review
request review on revisions
--abandon
abandon revisions
--reclaim
reclaim revisions
--close
close revisions
--reopen
reopen revisions
--plan-changes
plan changes for revisions
--resign
resign as a reviewer from revisions
--commandeer
commandeer revisions
-m,--comment <VALUE>
comment on the last revision
-r,--rev <REV>
local revision to update
--test-vcr <VALUE>
Path to a vcr file. If nonexistent, will record a new vcr transcript, otherwise will mock all http
requests using the specified vcr file. (ADVANCED)
Uncategorized commands
purge
command to delete untracked files from the working directory (DEPRECATED)
The functionality of this extension has been included in core Mercurial since version 5.7. Please use hg
purge ... instead. hg purge --confirm is now the default, unless the extension is enabled for backward
compatibility.
rebase
command to move sets of revisions to a different ancestor
This extension lets you rebase changesets in an existing Mercurial repository.
For more information: https://mercurial-scm.org/wiki/RebaseExtension
Commands
Change manipulation
rebase
move changeset (and descendants) to a different branch:
hg rebase [[-s REV]... | [-b REV]... | [-r REV]...] [-d REV] [OPTION]...
Rebase uses repeated merging to graft changesets from one part of history (the source) onto another (the
destination). This can be useful for linearizing local changes relative to a master development tree.
Published commits cannot be rebased (see hg help phases). To copy commits, see hg help graft.
If you don't specify a destination changeset (-d/--dest), rebase will use the same logic as hg merge to
pick a destination. if the current branch contains exactly one other head, the other head is merged with
by default. Otherwise, an explicit revision with which to merge with must be provided. (destination
changeset is not modified by rebasing, but new changesets are added as its descendants.)
Here are the ways to select changesets:
1. Explicitly select them using --rev.
2. Use --source to select a root changeset and include all of its descendants.
3. Use --base to select a changeset; rebase will find ancestors and their descendants which are not
also ancestors of the destination.
4. If you do not specify any of --rev, --source, or --base, rebase will use --base . as above.
If --source or --rev is used, special names SRC and ALLSRC can be used in --dest. Destination would be
calculated per source revision with SRC substituted by that single source revision and ALLSRC substituted
by all source revisions.
Rebase will destroy original changesets unless you use --keep. It will also move your bookmarks (even if
you do).
Some changesets may be dropped if they do not contribute changes (e.g. merges from the destination
branch).
Unlike merge, rebase will do nothing if you are at the branch tip of a named branch with two heads. You
will need to explicitly specify source and/or destination.
If you need to use a tool to automate merge/conflict decisions, you can specify one with --tool, see hg
help merge-tools. As a caveat: the tool will not be used to mediate when a file was deleted, there is no
hook presently available for this.
If a rebase is interrupted to manually resolve a conflict, it can be continued with --continue/-c,
aborted with --abort/-a, or stopped with --stop.
Examples:
• move "local changes" (current commit back to branching point) to the current branch tip after a pull:
hg rebase
• move a single changeset to the stable branch:
hg rebase -r 5f493448 -d stable
• splice a commit and all its descendants onto another part of history:
hg rebase --source c0c3 --dest 4cf9
• rebase everything on a branch marked by a bookmark onto the default branch:
hg rebase --base myfeature --dest default
• collapse a sequence of changes into a single commit:
hg rebase --collapse -r 1520:1525 -d .
• move a named branch while preserving its name:
hg rebase -r "branch(featureX)" -d 1.3 --keepbranches
• stabilize orphaned changesets so history looks linear:
hg rebase -r 'orphan()-obsolete()' -d 'first(max((successors(max(roots(ALLSRC) & ::SRC)^)-obsolete())::) + max(::((roots(ALLSRC) & ::SRC)^)-obsolete()))'
Configuration Options:
You can make rebase require a destination if you set the following config option:
[commands]
rebase.requiredest = True
By default, rebase will close the transaction after each commit. For performance purposes, you can
configure rebase to use a single transaction across the entire rebase. WARNING: This setting introduces a
significant risk of losing the work you've done in a rebase if the rebase aborts unexpectedly:
[rebase]
singletransaction = True
By default, rebase writes to the working copy, but you can configure it to run in-memory for better
performance. When the rebase is not moving the parent(s) of the working copy (AKA the "currently checked
out changesets"), this may also allow it to run even if the working copy is dirty:
[rebase]
experimental.inmemory = True
Return Values:
Returns 0 on success, 1 if nothing to rebase or there are unresolved conflicts.
Options:
-s,--source <REV[+]>
rebase the specified changesets and their descendants
-b,--base <REV[+]>

record
commands to interactively select changes for commit/qrefresh (DEPRECATED)
The feature provided by this extension has been moved into core Mercurial as hg commit --interactive.
Commands
Change creation
qrecord
interactively record a new patch:
hg qrecord [OPTION]... PATCH [FILE]...
See hg help qnew & hg help record for more information and usage.
record

releasenotes
generate release notes from commit messages (EXPERIMENTAL)
It is common to maintain files detailing changes in a project between releases. Maintaining these files
can be difficult and time consuming. The hg releasenotes command provided by this extension makes the
process simpler by automating it.
Commands
Change navigation
releasenotes
parse release notes from commit messages into an output file:
hg releasenotes [-r REV] [-c] FILE
Given an output file and set of revisions, this command will parse commit messages for release notes then
add them to the output file.
Release notes are defined in commit messages as ReStructuredText directives. These have the form:
.. directive:: title
content
Each directive maps to an output section in a generated release notes file, which itself is
ReStructuredText. For example, the .. feature:: directive would map to a New Features section.
Release note directives can be either short-form or long-form. In short- form, title is omitted and the
release note is rendered as a bullet list. In long form, a sub-section with the title title is added to
the section.
The FILE argument controls the output file to write gathered release notes to. The format of the file is:
Section 1
=========
...
Section 2
=========
...
Only sections with defined release notes are emitted.
If a section only has short-form notes, it will consist of bullet list:
Section
=======
* Release note 1
* Release note 2
If a section has long-form notes, sub-sections will be emitted:
Section
=======
Note 1 Title
------------
Description of the first long-form note.
Note 2 Title
------------
Description of the second long-form note.
If the FILE argument points to an existing file, that file will be parsed for release notes having the
format that would be generated by this command. The notes from the processed commit messages will be
merged into this parsed set.
During release notes merging:
• Duplicate items are automatically ignored
• Items that are different are automatically ignored if the similarity is greater than a threshold.
This means that the release notes file can be updated independently from this command and changes should
not be lost when running this command on that file. A particular use case for this is to tweak the
wording of a release note after it has been added to the release notes file.
The -c/--check option checks the commit message for invalid admonitions.
The -l/--list option, presents the user with a list of existing available admonitions along with their
title. This also includes the custom admonitions (if any).
Options:
-r,--rev <REV>
revisions to process for release notes
-c, --check
checks for validity of admonitions (if any)
-l, --list
list the available admonitions with their title
Uncategorized commands
relink
recreates hardlinks between repository clones
Commands
Repository maintenance
relink
recreate hardlinks between two repositories:
hg relink [ORIGIN]
When repositories are cloned locally, their data files will be hardlinked so that they only use the space
of a single repository.
Unfortunately, subsequent pulls into either repository will break hardlinks for any files touched by the
new changesets, even if both repositories end up pulling the same changes.
Similarly, passing --rev to "hg clone" will fail to use any hardlinks, falling back to a complete copy of
the source repository.
This command lets you recreate those hardlinks and reclaim that wasted space.
This repository will be relinked to share space with ORIGIN, which must be on the same local disk. If
ORIGIN is omitted, looks for "default-relink", then "default", in [paths].
Do not attempt any read operations on this repository while the command is running. (Both repositories
will be locked against writes.)
remotefilelog
remotefilelog causes Mercurial to lazilly fetch file contents (EXPERIMENTAL)
This extension is HIGHLY EXPERIMENTAL. There are NO BACKWARDS COMPATIBILITY GUARANTEES. This means that
repositories created with this extension may only be usable with the exact version of this
extension/Mercurial that was used. The extension attempts to enforce this in order to prevent repository
corruption.
remotefilelog works by fetching file contents lazily and storing them in a cache on the client rather
than in revlogs. This allows enormous histories to be transferred only partially, making them easier to
operate on.
Configs:
packs.maxchainlen specifies the maximum delta chain length in pack files
packs.maxpacksize specifies the maximum pack file size
packs.maxpackfilecount specifies the maximum number of packs in the
shared cache (trees only for now)
remotefilelog.backgroundprefetch runs prefetch in background when True
remotefilelog.bgprefetchrevs specifies revisions to fetch on commit and
update, and on other commands that use them. Different from pullprefetch.
remotefilelog.gcrepack does garbage collection during repack when True
remotefilelog.nodettl specifies maximum TTL of a node in seconds before
it is garbage collected
remotefilelog.repackonhggc runs repack on hg gc when True
remotefilelog.prefetchdays specifies the maximum age of a commit in
days after which it is no longer prefetched.
remotefilelog.prefetchdelay specifies delay between background
prefetches in seconds after operations that change the working copy parent
remotefilelog.data.gencountlimit constraints the minimum number of data
pack files required to be considered part of a generation. In particular, minimum number of
packs files > gencountlimit.
remotefilelog.data.generations list for specifying the lower bound of
each generation of the data pack files. For example, list ['100MB','1MB'] or ['1MB', '100MB']
will lead to three generations: [0, 1MB), [ 1MB, 100MB) and [100MB, infinity).
remotefilelog.data.maxrepackpacks the maximum number of pack files to
include in an incremental data repack.
remotefilelog.data.repackmaxpacksize the maximum size of a pack file for
it to be considered for an incremental data repack.
remotefilelog.data.repacksizelimit the maximum total size of pack files
to include in an incremental data repack.
remotefilelog.history.gencountlimit constraints the minimum number of
history pack files required to be considered part of a generation. In particular, minimum
number of packs files > gencountlimit.
remotefilelog.history.generations list for specifying the lower bound of
each generation of the history pack files. For example, list [ '100MB', '1MB'] or ['1MB',
'100MB'] will lead to three generations: [ 0, 1MB), [1MB, 100MB) and [100MB, infinity).
remotefilelog.history.maxrepackpacks the maximum number of pack files to
include in an incremental history repack.
remotefilelog.history.repackmaxpacksize the maximum size of a pack file
for it to be considered for an incremental history repack.
remotefilelog.history.repacksizelimit the maximum total size of pack
files to include in an incremental history repack.
remotefilelog.backgroundrepack automatically consolidate packs in the
background
remotefilelog.cachepath path to cache
remotefilelog.cachegroup if set, make cache directory sgid to this
group
remotefilelog.cacheprocess binary to invoke for fetching file data
remotefilelog.debug turn on remotefilelog-specific debug output
remotefilelog.excludepattern pattern of files to exclude from pulls
remotefilelog.includepattern pattern of files to include in pulls
remotefilelog.fetchwarning: message to print when too many
single-file fetches occur
remotefilelog.getfilesstep number of files to request in a single RPC
remotefilelog.getfilestype if set to 'threaded' use threads to fetch
files, otherwise use optimistic fetching
remotefilelog.pullprefetch revset for selecting files that should be
eagerly downloaded rather than lazily
remotefilelog.reponame name of the repo. If set, used to partition
data from other repos in a shared store.
remotefilelog.server if true, enable server-side functionality
remotefilelog.servercachepath path for caching blobs on the server
remotefilelog.serverexpiration number of days to keep cached server
blobs
remotefilelog.validatecache if set, check cache entries for corruption
before returning blobs
remotefilelog.validatecachelog if set, check cache entries for
corruption before returning metadata
Commands
Repository maintenance
prefetch
prefetch file revisions from the server:
hg prefetch [OPTIONS] [FILE...]
Prefetchs file revisions for the specified revs and stores them in the local remotefilelog cache. If no
rev is specified, the default rev is used which is the union of dot, draft, pullprefetch and
bgprefetchrev. File names or patterns can be used to limit which files are downloaded.
Return 0 on success.
Options:
-r,--rev <REV[+]>
prefetch the specified revisions
--repack
run repack after prefetch
-b,--base <VALUE>
rev that is assumed to already be local
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
[+] marked option can be specified multiple times
Uncategorized commands
gc
garbage collect the client and server filelog caches:
hg gc [REPO...]
garbage collect the client and server filelog caches
repack
hg repack [OPTIONS]
Options:
--background
run in a background process
--incremental
do an incremental repack
--packsonly
only repack packs (skip loose objects)
verifyremotefilelog
hg verifyremotefilelogs <directory>
Options:
-d, --decompress
decompress the filelogs first
remotenames
showing remotebookmarks and remotebranches in UI (EXPERIMENTAL)
By default both remotebookmarks and remotebranches are turned on. Config knob to control the individually
are as follows.
Config options to tweak the default behaviour:
remotenames.bookmarks
Boolean value to enable or disable showing of remotebookmarks (default: True)
remotenames.branches
Boolean value to enable or disable showing of remotebranches (default: True)
remotenames.hoistedpeer
Name of the peer whose remotebookmarks should be hoisted into the top-level namespace (default:
'default')
schemes
extend schemes with shortcuts to repository swarms
This extension allows you to specify shortcuts for parent URLs with a lot of repositories to act like a
scheme, for example:
[schemes]
py = http://code.python.org/hg/
After that you can use it like:
hg clone py://trunk/
Additionally there is support for some more complex schemas, for example used by Google Code:
[schemes]
gcode = http://{1}.googlecode.com/hg/
The syntax is taken from Mercurial templates, and you have unlimited number of variables, starting with
{1} and continuing with {2}, {3} and so on. This variables will receive parts of URL supplied, split by
/. Anything not specified as {part} will be just appended to an URL.
For convenience, the extension adds these schemes by default:
[schemes]
py = http://hg.python.org/
bb = https://bitbucket.org/
bb+ssh = ssh://hg@bitbucket.org/
gcode = https://{1}.googlecode.com/hg/
kiln = https://{1}.kilnhg.com/Repo/
You can override a predefined scheme by defining a new scheme with the same name.
Commands
Uncategorized commands
share
share a common history between several working directories
The share extension introduces a new command hg share to create a new working directory. This is similar
to hg clone, but doesn't involve copying or linking the storage of the repository. This allows working on
different branches or changes in parallel without the associated cost in terms of disk space.
Note: destructive operations or extensions like hg rollback should be used with care as they can result
in confusing problems.
Automatic Pooled Storage for Clones
When this extension is active, hg clone can be configured to automatically share/pool storage across
multiple clones. This mode effectively converts hg clone to hg clone + hg share. The benefit of using
this mode is the automatic management of store paths and intelligent pooling of related repositories.
The following share. config options influence this feature:
share.pool
Filesystem path where shared repository data will be stored. When defined, hg clone will
automatically use shared repository storage instead of creating a store inside each clone.
share.poolnaming
How directory names in share.pool are constructed.
"identity" means the name is derived from the first changeset in the repository. In this mode,
different remotes share storage if their root/initial changeset is identical. In this mode, the
local shared repository is an aggregate of all encountered remote repositories.
"remote" means the name is derived from the source repository's path or URL. In this mode, storage
is only shared if the path or URL requested in the hg clone command matches exactly to a
repository that was cloned before.
The default naming mode is "identity".
Sharing requirements and configs of source repository with shares:
By default creating a shared repository only enables sharing a common history and does not share
requirements and configs between them. This may lead to problems in some cases, for example when you
upgrade the storage format from one repository but does not set related configs in the shares.
Setting format.exp-share-safe = True enables sharing configs and requirements. This only applies to
shares which are done after enabling the config option.
For enabling this in existing shares, enable the config option and reshare.
For resharing existing shares, make sure your working directory is clean and there are no untracked
files, delete that share and create a new share.
Commands
Repository creation
share
create a new shared repository:
hg share [-U] [-B] SOURCE [DEST]
Initialize a new repository and working directory that shares its history (and optionally bookmarks) with
another repository.
Note using rollback or extensions that destroy/modify history (mq, rebase, etc.) can cause considerable
confusion with shared clones. In particular, if two shared clones are both updated to the same
changeset, and one of them destroys that changeset with rollback, the other clone will suddenly
stop working: all operations will fail with "abort: working directory has unknown parent". The
only known workaround is to use debugsetparents on the broken clone to reset it to a changeset
that still exists.
Options:
-U, --noupdate
do not create a working directory
-B, --bookmarks
also share bookmarks
--relative
point to source using a relative path
Repository maintenance
unshare
convert a shared repository to a normal one:
hg unshare
Copy the store data to the repo and remove the sharedpath data.
show
unified command to show various repository information (EXPERIMENTAL)
This extension provides the hg show command, which provides a central command for displaying
commonly-accessed repository data and views of that data.
The following config options can influence operation.
commands
show.aliasprefix
List of strings that will register aliases for views. e.g. s will effectively set config options
alias.s<view> = show <view> for all views. i.e. hg swork would execute hg show work.
Aliases that would conflict with existing registrations will not be performed.
Commands
Change navigation
show
show various repository information:
hg show VIEW
A requested view of repository data is displayed.
If no view is requested, the list of available views is shown and the command aborts.
Note There are no backwards compatibility guarantees for the output of this command. Output may change
in any future Mercurial release.
Consumers wanting stable command output should specify a template via -T/--template.
List of available views:
bookmarks bookmarks and their associated changeset
stack current line of work
work changesets that aren't finished
Options:
-T,--template <TEMPLATE>
display with template
sparse
allow sparse checkouts of the working directory (EXPERIMENTAL)
(This extension is not yet protected by backwards compatibility guarantees. Any aspect may break in
future releases until this notice is removed.)
This extension allows the working directory to only consist of a subset of files for the revision. This
allows specific files or directories to be explicitly included or excluded. Many repository operations
have performance proportional to the number of files in the working directory. So only realizing a subset
of files in the working directory can improve performance.
Sparse Config Files
The set of files that are part of a sparse checkout are defined by a sparse config file. The file defines
3 things: includes (files to include in the sparse checkout), excludes (files to exclude from the sparse
checkout), and profiles (links to other config files).
The file format is newline delimited. Empty lines and lines beginning with # are ignored.
Lines beginning with %include `` denote another sparse config file to include. e.g. ``%include
tests.sparse. The filename is relative to the repository root.
The special lines [include] and [exclude] denote the section for includes and excludes that follow,
respectively. It is illegal to have [include] after [exclude].
Non-special lines resemble file patterns to be added to either includes or excludes. The syntax of these
lines is documented by hg help patterns. Patterns are interpreted as glob: by default and match against
the root of the repository.
Exclusion patterns take precedence over inclusion patterns. So even if a file is explicitly included, an
[exclude] entry can remove it.
For example, say you have a repository with 3 directories, frontend/, backend/, and tools/. frontend/ and
backend/ correspond to different projects and it is uncommon for someone working on one to need the files
for the other. But tools/ contains files shared between both projects. Your sparse config files may
resemble:
# frontend.sparse
frontend/**
tools/**
# backend.sparse
backend/**
tools/**
Say the backend grows in size. Or there's a directory with thousands of files you wish to exclude. You
can modify the profile to exclude certain files:
[include]
backend/**
tools/**
[exclude]
tools/tests/**
Commands
Uncategorized commands
split
command to split a changeset into smaller ones (EXPERIMENTAL)
Commands
Change manipulation
split
split a changeset into smaller ones:
hg split [--no-rebase] [[-r] REV]
Repeatedly prompt changes and commit message for new changesets until there is nothing left in the
original changeset.
If --rev was not given, split the working directory parent.
By default, rebase connected non-obsoleted descendants onto the new changeset. Use --no-rebase to avoid
the rebase.
Options:
-r,--rev <REV>
revision to split
--rebase
rebase descendants after split (default: True)
-d,--date <DATE>
record the specified date as commit date
-u,--user <USER>
record the specified user as committer
sqlitestore
store repository data in SQLite (EXPERIMENTAL)
The sqlitestore extension enables the storage of repository data in SQLite.
This extension is HIGHLY EXPERIMENTAL. There are NO BACKWARDS COMPATIBILITY GUARANTEES. This means that
repositories created with this extension may only be usable with the exact version of this
extension/Mercurial that was used. The extension attempts to enforce this in order to prevent repository
corruption.
In addition, several features are not yet supported or have known bugs:
• Only some data is stored in SQLite. Changeset, manifest, and other repository data is not yet stored in
SQLite.
• Transactions are not robust. If the process is aborted at the right time during transaction
close/rollback, the repository could be in an inconsistent state. This problem will diminish once all
repository data is tracked by SQLite.
• Bundle repositories do not work (the ability to use e.g. hg -R <bundle-file> log to automatically
overlay a bundle on top of the existing repository).
• Various other features don't work.
This extension should work for basic clone/pull, update, and commit workflows. Some history rewriting
operations may fail due to lack of support for bundle repositories.
To use, activate the extension and set the storage.new-repo-backend config option to sqlite to enable new
repositories to use SQLite for storage.
strip
strip changesets and their descendants from history (DEPRECATED)
The functionality of this extension has been included in core Mercurial since version 5.7. Please use hg
debugstrip ... instead.
This extension allows you to strip changesets and all their descendants from the repository. See the
command help for details.
transplant
command to transplant changesets from another branch
This extension allows you to transplant changes to another parent revision, possibly in another
repository. The transplant is done using 'diff' patches.
Transplanted patches are recorded in .hg/transplant/transplants, as a map from a changeset hash to its
hash in the source repository.
Commands
Change manipulation
transplant
transplant changesets from another branch:
hg transplant [-s REPO] [-b BRANCH [-a]] [-p REV] [-m REV] [REV]...
Selected changesets will be applied on top of the current working directory with the log of the original
changeset. The changesets are copied and will thus appear twice in the history with different identities.
Consider using the graft command if everything is inside the same repository - it will use merges and
will usually give a better result. Use the rebase extension if the changesets are unpublished and you
want to move them instead of copying them.
If --log is specified, log messages will have a comment appended of the form:
(transplanted from CHANGESETHASH)
You can rewrite the changelog message with the --filter option. Its argument will be invoked with the
current changelog message as $1 and the patch as $2.
--source/-s specifies another repository to use for selecting changesets, just as if it temporarily had
been pulled. If --branch/-b is specified, these revisions will be used as heads when deciding which
changesets to transplant, just as if only these revisions had been pulled. If --all/-a is specified, all
the revisions up to the heads specified with --branch will be transplanted.
Example:
• transplant all changes up to REV on top of your current revision:
hg transplant --branch REV --all
You can optionally mark selected transplanted changesets as merge changesets. You will not be prompted to
transplant any ancestors of a merged transplant, and you can merge descendants of them normally instead
of transplanting them.
Merge changesets may be transplanted directly by specifying the proper parent changeset by calling hg
transplant --parent.
If no merges or revisions are provided, hg transplant will start an interactive changeset browser.
If a changeset application fails, you can fix the merge by hand and then resume where you left off by
calling hg transplant --continue/-c.
Options:
-s,--source <REPO>
transplant changesets from REPO
-b,--branch <REV[+]>
use this source changeset as head
-a, --all
pull all changesets up to the --branch revisions
-p,--prune <REV[+]>
skip over REV
-m,--merge <REV[+]>
merge at REV
--parent <REV>
parent to choose when transplanting merge
-e, --edit
invoke editor on commit messages
--log append transplant info to log message
--stop stop interrupted transplant
-c, --continue
continue last transplant session after fixing conflicts
--filter <CMD>
filter changesets through command
[+] marked option can be specified multiple times
uncommit
uncommit part or all of a local changeset (EXPERIMENTAL)
This command undoes the effect of a local commit, returning the affected files to their uncommitted
state. This means that files modified, added or removed in the changeset will be left unchanged, and so
will remain modified, added and removed in the working directory.
Commands
Change manipulation
unamend
undo the most recent amend operation on a current changeset:
hg unamend
This command will roll back to the previous version of a changeset, leaving working directory in state in
which it was before running hg amend (e.g. files modified as part of an amend will be marked as modified
hg status)
uncommit
uncommit part or all of a local changeset:
hg uncommit [OPTION]... [FILE]...
This command undoes the effect of a local commit, returning the affected files to their uncommitted
state. This means that files modified or deleted in the changeset will be left unchanged, and so will
remain modified in the working directory.
If no files are specified, the commit will be pruned, unless --keep is given.
Options:
--keep allow an empty commit after uncommitting
--allow-dirty-working-copy
allow uncommit with outstanding changes
-n,--note <TEXT>
store a note on uncommit
-I,--include <PATTERN[+]>
include names matching the given patterns
-X,--exclude <PATTERN[+]>
exclude names matching the given patterns
-m,--message <TEXT>
use text as commit message
-l,--logfile <FILE>
read commit message from file
-d,--date <DATE>
record the specified date as commit date
-u,--user <USER>
record the specified user as committer
-D, --currentdate
record the current date as commit date
-U, --currentuser
record the current user as committer
[+] marked option can be specified multiple times
win32mbcs
allow the use of MBCS paths with problematic encodings
Some MBCS encodings are not good for some path operations (i.e. splitting path, case conversion, etc.)
with its encoded bytes. We call such a encoding (i.e. shift_jis and big5) as "problematic encoding".
This extension can be used to fix the issue with those encodings by wrapping some functions to convert to
Unicode string before path operation.
This extension is useful for:
• Japanese Windows users using shift_jis encoding.
• Chinese Windows users using big5 encoding.
• All users who use a repository with one of problematic encodings on case-insensitive file system.
This extension is not needed for:
• Any user who use only ASCII chars in path.
• Any user who do not use any of problematic encodings.
Note that there are some limitations on using this extension:
• You should use single encoding in one repository.
• If the repository path ends with 0x5c, .hg/hgrc cannot be read.
• win32mbcs is not compatible with fixutf8 extension.
By default, win32mbcs uses encoding.encoding decided by Mercurial. You can specify the encoding by
config option:
[win32mbcs]
encoding = sjis
It is useful for the users who want to commit with UTF-8 log message.
win32text
perform automatic newline conversion (DEPRECATED)
Deprecation: The win32text extension requires each user to configure the extension again and again for
each clone since the configuration is not copied when cloning.
We have therefore made the eol as an alternative. The eol uses a version controlled file for its
configuration and each clone will therefore use the right settings from the start.
To perform automatic newline conversion, use:
[extensions]
win32text =
[encode]
** = cleverencode:
# or ** = macencode:
[decode]
** = cleverdecode:
# or ** = macdecode:
If not doing conversion, to make sure you do not commit CRLF/CR by accident:
[hooks]
pretxncommit.crlf = python:hgext.win32text.forbidcrlf
# or pretxncommit.cr = python:hgext.win32text.forbidcr
To do the same check on a server to prevent CRLF/CR from being pushed or pulled:
[hooks]
pretxnchangegroup.crlf = python:hgext.win32text.forbidcrlf
# or pretxnchangegroup.cr = python:hgext.win32text.forbidcr
zeroconf
discover and advertise repositories on the local network
The zeroconf extension will advertise hg serve instances over DNS-SD so that they can be discovered using
the hg paths command without knowing the server's IP address.
To allow other people to discover your repository using run hg serve in your repository:
$ cd test
$ hg serve
You can discover Zeroconf-enabled repositories by running hg paths:
$ hg paths
zc-test = http://example.com:8000/test
FILES
/etc/mercurial/hgrc, $HOME/.hgrc, .hg/hgrc
This file contains defaults and configuration. Values in .hg/hgrc override those in $HOME/.hgrc,
and these override settings made in the global /etc/mercurial/hgrc configuration. See hgrc(5) for
details of the contents and format of these files.
.hgignore
This file contains regular expressions (one per line) that describe file names that should be
ignored by hg. For details, see hgignore(5).
.hgsub
This file defines the locations of all subrepositories, and tells where the subrepository
checkouts came from. For details, see hg help subrepos.
.hgsubstate
This file is where Mercurial stores all nested repository states. NB: This file should not be
edited manually.
.hgtags
This file contains changeset hash values and text tag names (one of each separated by spaces) that
correspond to tagged versions of the repository contents. The file content is encoded using UTF-8.
.hg/last-message.txt
This file is used by hg commit to store a backup of the commit message in case the commit fails.
.hg/localtags
This file can be used to define local tags which are not shared among repositories. The file
format is the same as for .hgtags, but it is encoded using the local system encoding.
Some commands (e.g. revert) produce backup files ending in .orig, if the .orig file already exists and is
not tracked by Mercurial, it will be overwritten.
BUGS
Probably lots, please post them to the mailing list (see Resources below) when you find them.
