Description

       You can query/set/replace/unset Sqitch options with this command. The name is actually the section and
       the key separated by a dot, and the value will be escaped.

       Multiple lines can be added to an option by using the "--add" option. If you want to update or unset an
       option which can occur on multiple lines, a Perl regular expression "value_regex" needs to be given. Only
       the existing values that match the regex will be updated or unset. If you want to handle lines that do
       not match the regex, just prepend a single "!" (exclamation point) in front (see Examples).

       The "type" specifier can be "--int", "--num", or "--bool", to ensure that the variable(s) are of the
       given type and convert the value to the canonical form (simple integer for "--int", decimal number for
       "--num", a "true" or "false" string for "--bool") If no type specifier is passed, no checks or
       transformations are performed on the value.

       The "file-option" can be one of "--local", "--user", "--system", or "--file", which specify where the
       values will be read from or written to. The default is to assume the local config file in the current
       project directory, for editing, and the all files merged for fetching (see "Files").

       On success, the command returns the exit code 0.

Options

"--replace-all"
The default behavior is to replace at most one line. This replaces all lines matching the key (and
optionally the "value_regex").

"--add"
Adds a new line to the option without altering any existing values. This is the same as providing
"^$" as the value_regex in "--replace-all".

"--get"
Get the value for a given key (optionally filtered by a regex matching the value). Returns error code
1 if the key was not found and error code 2 if multiple values were found.

"--get-all"
Like "--get", but does not fail if the number of values for the key is not exactly one.

"--get-regexp"
Like "--get-all", but interprets the name as a regular expression and writes out the key names and
value.

"--local"
For writing options: write to the local ./sqitch.conf file. This is the default if no file option is
specified.

For reading options: read only from the local ./sqitch.conf file rather than from all available
files.

Files

       If  not  set  explicitly  with  "--file",  there are three files in which "sqitch config" will search for
       configuration options:

       ./sqitch.conf
           Local, project-specific configuration file.

       ~/.sqitch/sqitch.conf
           User-specific configuration file.

       $(prefix)/etc/sqitch/sqitch.conf
           System-wide configuration file.

Environment

       "SQITCH_CONFIG"
           Take the local configuration from the given file instead of ./sqitch.conf.

       "SQITCH_USER_CONFIG"
           Take the user configuration from the given file instead of ~/.sqitch/sqitch.conf.

       "SQITCH_SYSTEM_CONFIG"
           Take the system configuration from the given file instead of $($etc_prefix)/sqitch.conf.

Examples

       Given a ./sqitch.conf like this:

         #
         # This is the config file, and
         # a '#' or ';' character indicates
         # a comment
         #

         ; core variables
         [core]
                 ; Use PostgreSQL
                 engine    = pg

         ; Bundle command settings.
         [bundle]
                 from      = gamma
                 tags_only = false
                 dest_dir  = _build/sql

         ; Fuzzle command settings
         [core "fuzzle"]
                 clack        = foo
                 clack        = bar
                 clack        = barzlewidth

       You can set the "tags_only" setting to true with

         % sqitch config bundle.tags_only true

       The hypothetical "clack" key in the "core.fuzzle" section might need to set  "foo"  to  "hi"  instead  of
       "foo".  You can make the replacement by passing an additional argument to match the old value, which will
       be evaluated as a regular expression. Here's one way to make that change:

         % sqitch config core.fuzzle.clack hi '^foo$'

       To delete the entry for "bundle.from", do

         % sqitch config --unset bundle.from

       If you want to delete an entry for a multivalue  setting  (like  "core.fuzzle.clack"),  provide  a  regex
       matching the value of exactly one line.  This example deletes the "bar" value:

         % sqitch config --unset core.fuzzle.clack '^bar$'

       To query the value for a given key, do:

         % sqitch config --get core.engine

       Or:

         % sqitch config core.engine

       Or, to query a multivalue setting for only those values that match "/ba/":

         % sqitch config --get core.fuzzle.clack ba

       If you want to know all the values for a multivalue setting, do:

         % sqitch config --get-all core.fuzzle.clack

       If you like to live dangerously, you can replace all "core.fuzzle.clack" with a new one with

         % sqitch config --replace-all core.fuzzle.clack funk

       However,  if  you  only  want  to  replace  lines  that  don't  match "bar", prepend the matching regular
       expression with an exclamation point ("!"), like so:

         % sqitch config --replace-all core.fuzzle.clack yow '!bar'

       To match only values with an exclamation mark, you have to escape it:

         % sqitch config section.key '[!]'

       To add a new setting without altering any of the existing ones, use:

         % sqitch config --add core.fuzzle.set widget=fred

Configuration File

The sqitch configuration file contains a number of variables that affect the sqitch command's behavior.
The ./sqitch.conf file local to each project is used to store the configuration for that project, and
$HOME/.sqitch/sqitch.conf is used to store a per-user configuration as fallback values for the
./sqitch.conf file. The file $($etc_prefix)/sqitch.conf can be used to store a system-wide default
configuration.

The variables are divided into sections, wherein the fully qualified variable name of the variable itself
is the last dot-separated segment and the section name is everything before the last dot. The variable
names are case-insensitive, allow only alphanumeric characters and -, and must start with an alphabetic
character. Some variables may appear multiple times.

Syntax
The syntax is fairly flexible and permissive; white space is mostly ignored. The "#" and ";" characters
begin comments to the end of line, blank lines are ignored.

The file consists of sections and variables. A section begins with the name of the section in square
brackets and continues until the next section begins. Section names are not case sensitive. Only
alphanumeric characters, "-" and "." are allowed in section names. Each variable must belong to some
section, which means that there must be a section header before the first setting of a variable.

Sections can be further divided into subsections. To begin a subsection put its name in double quotes,
separated by space from the section name, in the section header, like in the example below:

[section "subsection"]

Subsection names are case sensitive and can contain any characters except newline (double quote and
backslash have to be escaped as "\"" and "\\", respectively). Section headers cannot span multiple lines.
Variables may belong directly to a section or to a given subsection. You can have "[section]" if you have
"[section "subsection"]", but you don't need to.

All the other lines (and the remainder of the line after the section header) are recognized as setting
variables, in the form "name = value". If there is no equal sign on the line, the entire line is taken as
name and the variable is recognized as boolean "true". The variable names are case-insensitive, allow
only alphanumeric characters and "-", and must start with an alphabetic character. There can be more than
one value for a given variable; we say then that the variable is multivalued.

Leading and trailing whitespace in a variable value is discarded. Internal whitespace within a variable
value is retained verbatim.

The values following the equals sign in variable assignments are either strings, integers, numbers, or
booleans. Boolean values may be given as yes/no, 1/0, true/false or on/off. Case is not significant in
boolean values, when converting value to the canonical form using the "--bool" type specifier; "sqitch
config" will ensure that the output is "true" or "false".

String values may be entirely or partially enclosed in double quotes. You need to enclose variable values
in double quotes if you want to preserve leading or trailing whitespace, or if the variable value
contains comment characters (i.e. it contains "#" or ";"). Double quote and backslash characters in
variable values must be escaped: use "\"" for """ and "\\" for "\".

The following escape sequences (beside "\"" and "\\") are recognized: "\n" for newline character (NL),
"\t" for horizontal tabulation (HT, TAB) and "\b" for backspace (BS). No other character escape sequence
or octal character sequence is valid.

Variable values ending in a "\" are continued on the next line in the customary UNIX fashion.

Some variables may require a special value format.

Variables
Note that this list is not comprehensive and not necessarily complete. For command-specific variables,
you will find a more detailed description in the appropriate manual page.

"core.plan_file"
The plan file to use. Defaults to $top_dir/sqitch.plan.

"core.engine"
The database engine to use. Supported engines include:

• "pg" - PostgreSQL <https://postgresql.org/>, Postgres-XC
<https://sourceforge.net/projects/postgres-xc/>, and YugabyteDB
<https://www.yugabyte.com/yugabytedb/>

• "sqlite" - SQLite <https://sqlite.org/>

• "oracle" - Oracle <https://www.oracle.com/us/products/database/>

• "mysql" - MySQL <https://dev.mysql.com/> and MariaDB <https://mariadb.com/>

• "firebird" - Firebird <https://www.firebirdsql.org/>

• "vertica" - Vertica <https://my.vertica.com/>

• "exasol" - Exasol <https://www.exasol.com/>

• "snowflake" - Snowflake <https://www.snowflake.net/>

• "cockroach" - CockroachDB <https://www.cockroachlabs.com/product/>

"core.top_dir"
Path to directory containing deploy, revert, and verify SQL scripts. It should contain subdirectories
named "deploy", "revert", and (optionally) "verify". These may be overridden by "deploy_dir",
"revert_dir", and "verify_dir". Defaults to ".".

"core.deploy_dir"
Path to a directory containing SQL deployment scripts. Overrides the value implied by "core.top_dir".

"core.revert_dir"
Path to a directory containing SQL reversion scripts. Overrides the value implied by "core.top_dir".

"core.verify_dir"
Path to a directory containing SQL verify scripts. Overrides the value implied by "core.top_dir".

"core.extension"
The file name extension on deploy, revert, and verify SQL scripts. Defaults to "sql".

"core.verbosity"
An integer determining how verbose Sqitch should be. Defaults to 1. Set to 0 to silence status
messages and to 2 or three to increase verbosity. Error message output will not be affected by this
property.

"core.pager"
The command to use as a pager program. This overrides the "PAGER" environment variable on UNIX like
systems. Both can be overridden by setting the $SQITCH_PAGER environment variable. If none of these
variables are set, Sqitch makes a best-effort search among the commonly installed pager programs like
"less" and "more".

"core.editor"
The command to use as a editor program. This overrides the "EDITOR" environment variable on UNIX like
systems. Both can be overridden by setting the $SQITCH_EDITOR environment variable. If none of these
variables are set, Sqitch defaults to "notepad.exe" on Windows and "vi" elsewhere.

"user"

Configuration properties that identify the user.

"user.name"
Your full name, to be recorded in changes and tags added to the plan, and to commits to the database.

"user.email"
Your email address, to be recorded in changes and tags added to the plan, and to commits to the
database.

"engine.$engine"

Each supported engine offers a set of configuration variables, falling under the key "engine.$engine"
where $engine may be any value accepted for "core.engine".

"engine.$engine.target"
A database target, either the name of target managed by the "target" command, or a database
connection URI. If it's a target name, then the associated "uri", "registry", and "client" values
will override any values specified for the values below. Targets are the preferred way to configure
engines on a per-database basis, and the one specified here should be considered the default.

"engine.$engine.uri"
A database connection URI.

"engine.$engine.registry"
The name of the Sqitch registry schema or database. Sqitch will store its own data in this schema.

"engine.$engine.client"
Path to the engine command-line client. Defaults to the first instance found in the path.

Notes on engine-specific configuration:

"engine.pg.registry"
For the PostgreSQL engine, the "registry" value identifies the schema for Sqitch to use for its own
data. No other data should be stored there. Defaults to "sqitch".

"engine.sqlite.registry"
For the SQLite engine, if the "registry" value looks like an absolute path, then it will be the
database file. Otherwise, it will be in the same directory as the database specified by the "uri".
Defaults to "sqitch".

"engine.mysql.registry"
For the MySQL engine, the "registry" value identifies the database for Sqitch to use for its own
data. If you need to manage multiple databases on a single server, and don't want them all to share
the same registry, change this property to a value specific for your database. Defaults to "sqitch".

"engine.oracle.registry"
For Oracle, "registry" value identifies the schema for Sqitch to use for its own data. No other data
should be stored there. Uses the current schema by default (usually the same name as the connection
user).

"engine.firebird.registry"
For the Firebird engine, if the "registry" value looks like an absolute path, then it will be the
database file. Otherwise, it will be in the same directory as the database specified by the "uri".
Defaults to "sqitch.$extension", where $extension is the same as that in the "uri", if any.

"engine.vertica.registry"
For the Vertica engine, the "registry" value identifies the schema for Sqitch to use for its own
data. No other data should be stored there. Defaults to "sqitch".

"engine.exasol.registry"
For the Exasol engine, the "registry" value identifies the schema for Sqitch to use for its own data.
No other data should be stored there. Defaults to "sqitch".

"engine.snowflake.registry"
For the Snowflake engine, the "registry" value identifies the schema for Sqitch to use for its own
data. No other data should be stored there. Defaults to "sqitch".

"core.vcs"

Configuration properties for the version control system. Currently, only Git is supported.

"core.vcs.client"
Path to the "VCS" command-line client. Defaults to the first instance of git found in the path.

"user"

"user.email"
Your email address to be recorded in any newly planned changes.

"user.name"
Your full name to be recorded in any newly planned changes.

Sqitch

       Part of the sqitch suite.
