NAME
arc - arcanist, a code review and revision management utility
SYNOPSIS
arc command [options] [args] This help file provides a detailed command reference.
COMMAND REFERENCE
alias
alias command
alias command target -- [options]
Supports: cli Create an alias from command to target (optionally, with options). For example:
arc alias fpatch patch -- --force
...will create a new 'arc' command, 'arc fpatch', which invokes 'arc patch --force ...' when run.
NOTE: use "--" before specifying options!
If you start an alias with "!", the remainder of the alias will be invoked as a shell command. For
example, if you want to implement 'arc ls', you can do so like this:
arc alias ls '!ls'
You can now run "arc ls" and it will behave like "ls". Of course, this example is silly and would
make your life worse.
You can not overwrite builtins, including 'alias' itself. The builtin will always execute, even if it
was added after your alias.
To remove an alias, run:
arc alias fpatch
Without any arguments, 'arc alias' will list aliases.
amend [--revision revision_id] [--show]
Supports: git, hg Amend the working copy, synchronizing the local commit message from Differential.
Supported in Mercurial 2.2 and newer.
--revision revision_id
Use the message from a specific revision. If you do not specify a revision, arc will guess which
revision is in the working copy.
--show
Show the amended commit message, without modifying the working copy.
anoid
There's only one way to find out...
backout
Reverts/backouts on a previous commit. Supports: git, hg
Command is used like this: arc backout <commithash> | <diff revision> Entering a differential
revision will only work if there is only one commit associated with the revision. This requires
your working copy is up to date and that the commit exists in the working copy.
bookmark [options]
bookmark name [start]
Supports: hg Alias for arc feature.
--by-status
Sort branches by status instead of time.
--output format
With 'json', show features in machine-readable JSON format.
--view-all
Include closed and abandoned revisions.
branch [options]
branch name [start]
Supports: git Alias for arc feature.
--by-status
Sort branches by status instead of time.
--output format
With 'json', show features in machine-readable JSON format.
--view-all
Include closed and abandoned revisions.
browse [options] path ...
browse [options] object ...
Supports: git, hg, svn Open a file or object (like a task or revision) in your web browser.
$ arc browse README # Open a file in Diffusion.
$ arc browse T123 # View a task.
$ arc browse HEAD # View a symbolic commit.
Set the 'browser' value using 'arc set-config' to select a browser. If no browser is set, the command
will try to guess which browser to use.
--branch branch_name
Default branch name to view on server. Defaults to "master".
--force
Open arguments as paths, even if they do not exist in the working copy.
call-conduit method
Supports: http, https Allows you to make a raw Conduit method call:
- Run this command from a working directory.
- Call parameters are REQUIRED and read as a JSON blob from stdin.
- Results are written to stdout as a JSON blob.
This workflow is primarily useful for writing scripts which integrate with Phabricator. Examples:
$ echo '{}' | arc call-conduit conduit.ping
$ echo '{"phid":"PHID-FILE-xxxx"}' | arc call-conduit file.download
close task_id [options]
Close a task or otherwise update its status.
--list-statuses
Show available status options and exit.
--message comment, -m comment
Provide a comment with your status change.
--status status, -s status
Specify a new status. Valid status options can be seen with the `list-statuses` argument.
close-revision [options] revision
Supports: git, hg, svn Close a revision which has been committed (svn) or pushed (git, hg). You
should not normally need to do this: arc commit (svn), arc amend (git, hg), arc land (git, hg), or
repository tracking on the master remote repository should do it for you. However, if these
mechanisms have failed for some reason you can use this command to manually change a revision status
from "Accepted" to "Closed".
--finalize
Close only if the repository is untracked and the revision is accepted. Continue even if the
close can't happen. This is a soft version of '' used by other workflows.
--quiet
Do not print a success message.
commit [--revision revision_id] [--show]
Supports: svn Commit a revision which has been accepted by a reviewer.
--revision revision_id
Commit a specific revision. If you do not specify a revision, arc will look for committable
revisions.
--show
Show the command which would be issued, but do not actually commit anything.
cover [--rev revision] [path ...]
Supports: svn, git, hg Cover your... professional reputation. Show blame for the lines you changed in
your working copy (svn) or since some commit (hg, git). This will take a minute because blame takes
a minute, especially under SVN.
--rev revision
Supports: git, hg Cover changes since a specific revision.
diff [paths] (svn)
diff [commit] (git, hg)
Supports: git, svn, hg Generate a Differential diff or revision from local changes.
Under git and mercurial, you can specify a commit (like HEAD^^^ or master) and Differential will
generate a diff against the merge base of that commit and your current working directory parent.
Under svn, you can choose to include only some of the modified files in the working copy in the diff
by specifying their paths. If you omit paths, all changes are included in the diff.
--add-all, -a
Automatically add all unstaged and uncommitted files to the commit.
--advice
Require excuse for lint advice in addition to lint warnings and errors.
--allow-untracked
Skip checks for untracked files in the working copy.
--amend-all
When linting git repositories, amend HEAD with all patches suggested by lint without prompting.
--amend-autofixes
When linting git repositories, amend HEAD with autofix patches suggested by lint without
prompting.
--apply-patches
Apply patches suggested by lint to the working copy without prompting.
--base rules
Supports: git, hg Additional rules for determining base revision.
--browse
After creating a diff or revision, open it in a web browser.
--cache bool
0 to disable lint cache, 1 to enable (default).
--cc usernames
When creating a revision, add CCs.
--coverage
Always enable coverage information.
--create
Always create a new revision.
--edit
Supports: git, hg When updating a revision under git, edit revision information before updating.
--encoding encoding
Attempt to convert non UTF-8 hunks into specified encoding.
--excuse excuse
Provide a prepared in advance excuse for any lints/tests shall they fail.
--head commit
Supports: git Specify the end of the commit range. This disables many Arcanist/Phabricator
features which depend on having access to the working copy.
--ignore-unsound-tests
Ignore unsound test failures without prompting.
--json
Emit machine-readable JSON. EXPERIMENTAL! Probably does not work!
--less-context
Normally, files are diffed with full context: the entire file is sent to Differential so
reviewers can 'show more' and see it. If you are making changes to very large files with tens of
thousands of lines, this may not work well. With this flag, a diff will be created that has only
a few lines of context.
--lintall
Raise all lint warnings, not just those on lines you changed.
--message message, -m message
When updating a revision, use the specified message instead of prompting.
--message-file file, -F file
When creating a revision, read revision information from this file.
--never-apply-patches
Never apply patches suggested by lint.
--no-amend
Never amend commits in the working copy with lint patches.
--no-coverage
Always disable coverage information.
--no-diff
Only run lint and unit tests. Intended for internal use.
--nolint
Do not run lint.
--nounit
Do not run unit tests.
--only
Only generate a diff, without running lint, unit tests, or other auxiliary steps. See also
--preview.
--only-new bool
Display only lint messages not present in the original code.
--plan-changes
Create or update a revision without requesting a code review.
--preview
Instead of creating or updating a revision, only create a diff, which you may later attach to a
revision. This still runs lint unit tests. See also --only.
--raw
Read diff from stdin, not from the working copy. This disables many Arcanist/Phabricator features
which depend on having access to the working copy.
--raw-command command
Generate diff by executing a specified command, not from the working copy. This disables many
Arcanist/Phabricator features which depend on having access to the working copy.
--reviewers usernames
When creating a revision, add reviewers.
--skip-binaries
Do not upload binaries (like images).
--skip-staging
Do not copy changes to the staging area.
--uncommitted
Supports: hg Suppress warning about uncommitted changes.
--update revision_id
Always update a specific revision.
--use-commit-message commit, -C commit
Supports: git Read revision information from a specific commit.
--verbatim
Supports: hg, git When creating a revision, try to use the working copy commit message verbatim,
without prompting to edit it. When updating a revision, update some fields from the local commit
message.
download file [--as name] [--show]
Supports: filesystems Download a file to local disk, e.g.:
$ arc download F33 # Download file 'F33'
--as name
Save the file with a specific name rather than the default.
--show
Write file to stdout instead of to disk.
export [paths] format (svn)
export [commit_range] format (git, hg)
export --revision revision_id format
export --diff diff_id format
Supports: svn, git, hg Export the local changeset (or a Differential changeset) to a file, in some
format: git diff (--git), unified diff (--unified), or arc bundle (--arcbundle path) format.
--arcbundle file
Export change as an arc bundle. This format can represent all changes. These bundles can be
applied with 'arc patch'.
--diff diff_id
Instead of exporting changes from the working copy, export them from a Differential diff.
--encoding encoding
Attempt to convert non UTF-8 patch into specified encoding.
--git
Export change as a git patch. This format is more complete than unified, but less complete than
arc bundles. These patches can be applied with 'git apply' or 'arc patch'.
--revision revision_id
Instead of exporting changes from the working copy, export them from a Differential revision.
--unified
Export change as a unified patch. This format is less complete than git patches or arc bundles.
These patches can be applied with 'patch' or 'arc patch'.
feature [options]
feature name [start]
Supports: git, hg A wrapper on 'git branch' or 'hg bookmark'.
Without name, it lists the available branches and their revision status.
With name, it creates or checks out a branch. If the branch name doesn't exist and is in format D123
then the branch of revision D123 is checked out. Use start to specify where the new branch will
start. Use 'arc.feature.start.default' to set the default feature start location.
--by-status
Sort branches by status instead of time.
--output format
With 'json', show features in machine-readable JSON format.
--view-all
Include closed and abandoned revisions.
flag [object ...]
flag object --clear
flag object [--edit] [--color color] [--note note]
In the first form, list objects you've flagged. You can provide the names of one or more objects
(Maniphest tasks T[7m#, Differential revisions D[m#, Diffusion references rXXX???, or PHIDs
PHID-XXX-???) to print only flags for those objects.
In the second form, clear an existing flag on one object.
In the third form, create or update a flag on one object. Color defaults to blue and note to empty,
but if you omit both you must pass --edit.
--clear
Delete the flag on an object.
--color color
Set the color of a flag.
--edit
Edit the flag on an object.
--note note
Set the note on a flag.
get-config [options] -- [name ...]
Supports: cli Reads an arc configuration option. With no argument, reads all options.
With --verbose, shows detailed information about one or more options.
--verbose
Show detailed information about options.
help [command]
help --full
Supports: english Shows this help. With command, shows help about a specific command.
--full
Print detailed information about each command.
install-certificate [uri]
Supports: http, https Installs Conduit credentials into your ~/.arcrc for the given install of
Phabricator. You need to do this before you can use 'arc', as it enables 'arc' to link your command-
line activity with your account on the web. Run this command from within a project directory to
install that project's certificate, or specify an explicit URI (like
"https://phabricator.example.com/").
land [options] [ref]
Supports: git, hg
Publish an accepted revision after review. This command is the last step in the standard Differential
pre-publish code review workflow.
This command merges and pushes changes associated with an accepted revision that are currently
sitting in ref, which is usually the name of a local branch. Without ref, the current working copy
state will be used.
Under Git: branches, tags, and arbitrary commits (detached HEADs) may be landed.
Under Mercurial: branches and bookmarks may be landed, but only onto a target of the same type. See
T3855.
The workflow selects a target branch to land onto and a remote where the change will be pushed to.
A target branch is selected by examining these sources in order:
- the B<--onto> flag;
- the upstream of the current branch, recursively (Git only);
- the I<arc.land.onto.default> configuration setting;
- or by falling back to a standard default:
- "master" in Git;
- "default" in Mercurial.
A remote is selected by examining these sources in order:
- the B<--remote> flag;
- the upstream of the current branch, recursively (Git only);
- or by falling back to a standard default:
- "origin" in Git;
- the default remote in Mercurial.
After selecting a target branch and a remote, the commits which will be landed are printed.
With --preview, execution stops here, before the change is merged.
The change is merged with the changes in the target branch, following these rules:
In repositories with mutable history or with --squash, this will perform a squash merge (the entire
branch will be represented as one commit after the merge).
In repositories with immutable history or with --merge, this will perform a strict merge (a merge
commit will always be created, and local commits will be preserved).
The resulting commit will be given an up-to-date commit message describing the final state of the
revision in Differential.
In Git, the merge occurs in a detached HEAD. The local branch reference (if one exists) is not
updated yet.
With --hold, execution stops here, before the change is pushed.
The change is pushed into the remote.
Consulting mystical sources of power, the workflow makes a guess about what state you wanted to end
up in after the process finishes and the working copy is put into that state.
The branch which was landed is deleted, unless the --keep-branch flag was passed or the landing
branch is the same as the target branch.
--delete-remote
Delete the feature branch in the remote after landing it.
--hold
Prepare the change to be pushed, but do not actually push it.
--keep-branch
Keep the feature branch after pushing changes to the remote (by default, it is deleted).
--merge
Supports: git Perform a --no-ff merge, not a --squash merge. If the project is marked as having
an immutable history, this is the default behavior.
--onto master
Land feature branch onto a branch other than the default ('master' in git, 'default' in hg). You
can change the default by setting 'arc.land.onto.default' with `arc set-config` or for the entire
project in .arcconfig.
--preview
Prints the commits that would be landed. Does not actually modify or land the commits.
--remote origin
Push to a remote other than the default ('origin' in git).
--revision id
Use the message from a specific revision, rather than inferring the revision based on branch
content.
--squash
Perform a --squash merge, not a --no-ff merge. If the project is marked as having a mutable
history, this is the default behavior.
--update-with-merge
Supports: git When updating the feature branch, use merge instead of rebase. This is the default
behavior. Setting arc.land.update.default to 'merge' can also be used to make this the default.
--update-with-rebase
Supports: git When updating the feature branch, use rebase instead of merge. This might make
things work better in some cases. Set arc.land.update.default to 'rebase' to make this the
default.
liberate [path]
Supports: libphutil Create or update a libphutil library, generating required metadata files like
init.php.
--all
Drop the module cache before liberating. This will completely reanalyze the entire library.
Thorough, but slow!
--force-update
Force the library map to be updated, even in the presence of lint errors.
--library-name name
Use a flag for library name rather than awaiting user input.
lint [options] [paths]
lint [options] --rev [rev]
Supports: git, svn, hg Run static analysis on changes to check for mistakes. If no files are
specified, lint will be run on all files which have been modified.
--amend-all
When linting git repositories, amend HEAD with all patches suggested by lint without prompting.
--amend-autofixes
When linting git repositories, amend HEAD with autofix patches suggested by lint without
prompting.
--apply-patches
Apply patches suggested by lint to the working copy without prompting.
--cache bool
0 to disable cache, 1 to enable. The default value is
determined by 'arc.lint.cache' in configuration, which defaults
to off. See notes in 'arc.lint.cache'.
--engine classname
Override configured lint engine for this project.
--everything
Lint all files in the project.
--lintall
Show all lint warnings, not just those on changed lines. When paths are specified, this is the
default behavior.
--never-apply-patches
Never apply patches suggested by lint.
--only-changed
Show lint warnings just on changed lines. When no paths are specified, this is the default. This
differs from only-new in cases where line modifications introduce lint on other unmodified lines.
--only-new bool
Supports: git, hg Display only messages not present in the original code.
--outfile path
Output the linter results to a file. Defaults to stdout.
--output format
With 'summary', show lint warnings in a more compact format. With 'json', show lint warnings in
machine-readable JSON format. With 'none', show no lint warnings. With 'compiler', show lint
warnings in suitable for your editor. With 'xml', show lint warnings in the Checkstyle XML
format.
--rev revision
Supports: git, hg Lint changes since a specific revision.
--severity string
Set minimum message severity. One of: 'advice', 'autofix', 'warning', 'error', 'disabled'.
Defaults to 'advice'.
linters [options] [name]
Supports: cli List the available and configured linters, with information about what they do and
which versions are installed.
if name is provided, the linter with that name will be displayed.
--search search
Search for linters. Search is case-insensitive, and is performedagainst name and description of
each linter.
--verbose
Show detailed information, including options.
list
Supports: git, svn, hg List your open Differential revisions.
paste [--title title] [--lang language] [--json]
paste id [--json]
Supports: text Share and grab text using the Paste application. To create a paste, use stdin to
provide the text:
$ cat list_of_ducks.txt | arc paste
To retrieve a paste, specify the paste ID:
$ arc paste P123
--json
Output in JSON format.
--lang language
Language for syntax highlighting.
--title title
Title for the paste.
patch D12345
patch --revision revision_id
patch --diff diff_id
patch --patch file
patch --arcbundle bundlefile
Supports: git, svn, hg Apply the changes in a Differential revision, patchfile, or arc bundle to the
working copy.
--arcbundle bundlefile
Apply changes from an arc bundle generated with 'arc export'.
--diff diff_id
Apply changes from a Differential diff. Normally you want to use --revision to get the most
recent changes, but you can specifically apply an out-of-date diff or a diff which was never
attached to a revision by using this flag.
--encoding encoding
Attempt to convert non UTF-8 patch into specified encoding.
--force
Do not run any sanity checks.
--nobranch
Supports: git, hg Normally, a new branch (git) or bookmark (hg) is created and then the patch is
applied and committed in the new branch/bookmark. This flag cherry-picks the resultant commit
onto the original branch and deletes the temporary branch.
--nocommit
Supports: git, hg Normally under git/hg, if the patch is successful, the changes are committed to
the working copy. This flag prevents the commit.
--patch patchfile
Apply changes from a git patchfile or unified patchfile.
--revision revision_id
Apply changes from a Differential revision, using the most recent diff that has been attached to
it. You can run 'arc patch D12345' as a shorthand.
--skip-dependencies
Supports: git, hg Normally, if a patch has dependencies that are not present in the working copy,
arc tries to apply them as well. This flag prevents such work.
--update
Supports: git, svn, hg Update the local working copy before applying the patch.
revert Please use arc backout instead
set-config [options] -- name value
Supports: cli Sets an arc configuration option.
Options are either user (apply to all arc commands you invoke from the current user) or local (apply
only to the current working copy). By default, user configuration is written. Use --local to write
local configuration.
User values are written to '~/.arcrc' on Linux and Mac OS X, and an undisclosed location on Windows.
Local values are written to an arc directory under either .git, .hg, or .svn as appropriate.
--local
Set a local config value instead of a user one.
shell-complete --current N -- [argv]
Supports: bash, etc. Implements shell completion. To use shell completion, source the appropriate
script from 'resources/shell/' in your .shellrc.
