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
  ; Revert command settings
  [core "revert"]
          set        = foo=bar
          set        = baz=yo

You can set the "tags_only" setting to true with

  % sqitch config bundle.tags_only true

The hypothetical "set" key in the "core.revert" section might need to set "foo" to ``hi'' instead of ``bar''. Here's how to make that change:

  % sqitch config core.revert.set foo=bar foo=hi

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.revert.set"), provide a regex matching the value of exactly one line.

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.revert.set ba

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

  % sqitch config --get-all core.revert.set

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

  % sqitch config --replace-all core.revert.set bring=funk

However, if you only want to replace the line without "baz", do something like this:

  % sqitch config core.revert.set = '!baz'

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

  % sqitch config section.key value '[!]'

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

  % sqitch config core.revert.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 <http://postgresql.org/> and Postgres-XC <http://sourceforge.net/>
"sqlite" - SQLite <http://sqlite.org/>
"oracle" - Oracle <http://www.oracle.com/us/products/database/>
"mysql" - MySQL <http://dev.mysql.com/> and MariaDB <https://mariadb.com/>
"firebird" - Firebird <http://www.firebirdsql.org/>
"vertica" - Vertica <https://my.vertica.com/>

"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.

"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".

"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.
