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.

See also Files.

--user

For writing options: write to the user ~/.sqitch/sqitch.conf file rather than the repository ./sqitch.conf.

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

See also Files.

--system

For writing options: write to system-wide $(etc_path)/sqitch.conf file rather than the repository ./sqitch.conf.

For reading options: read only from system-wide $($etc_prefix)/sqitch.conf file rather than from all available files.

See also Files.

-f config-file, --file config-file

Use the given config file instead of the one specified by $SQITCH_CONFIG.

--remove-section

Remove the given section from the configuration file.

--rename-section

Rename the given section to a new name.

--unset

Remove the line matching the key from config file.

--unset-all

Remove all lines matching the key from config file.

-l, --list

List all variables set in config file.

--bool

sqitch config will ensure that the output is "true" or "false".

--int

sqitch config will ensure that the output is a simple integer.

--num

sqitch config will ensure that the output is a simple decimal number.

--bool-or-int

sqitch config will ensure that the output matches the format of either --bool or --int, as described above.

-e, --edit

Opens an editor to modify the specified config file; either --local, --user, --system, or --file. If none of those options is specified, the local file will be opened.

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.

$($etc_prefix)/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]
        uri       = https://github.com/theory/sqitch/
        ; Use PostgreSQL
        engine    = pg

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

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

You can set the the tags_only setting to true with

% sqitch config bundle.tags_only true

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

% sqitch config core.pg.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.pg.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.pg.set ba

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

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

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

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

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

% sqitch config core.pg.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.pg.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.uri

A uniform resource identifier that uniquely identifies the project. Used to generate unique IDs for project changes, and so should be consistently used in the project, but not shared across projects. Thus it is recommended to always be used in the local configuration file, but not the user or system configuration files.

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

• mysql - MySQL

• sqlite - SQLite

core.top_dir

Path to directory containing deployment, reversion, and test SQL scripts. It should contain subdirectories named deploy, revert, and (optionally) test. These may be overridden by deploy_dir, revert_dir, and test_dir. Defaults to ./sql.

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.test_dir

Path to a directory containing SQL test scripts. Overrides the value implied by core.top_dir.

core.extension

The file name extension on deployment, reversion, and test 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.pg

Configuration properties for the PostgreSQL engine.

core.pg.client

Path to the psql command-line client. Defaults to the first instance found in the path.

core.pg.username

User name to use when connecting to the PostgreSQL database. Defaults to the contents of the $PGUSER environment variable or to the current system user name.

core.pg.password

Password to use when connecting to the PostgreSQL database. Defaults to the contents of the $PGPASSWORD environment variable or to the relevant line in ~/.pgpass, if available.

core.pg.db_name

Name of the PostgreSQL database. Defaults to the same as username or to the contents of the PGDATABASE environment variable.

core.pg.host

Host name to use when connecting to the database. Defaults to the contents of the $PGHOST environment variable.

core.pg.port

Port number to connect to. Does not apply to all engines. Defaults to the contents of the $PGPORT environment variable.

core.pg.sqitch_schema

The name of the schema in which Sqitch metadata will be stored. No other data should be stored in this schema. Defaults to sqitch.
