Name

       sqitch-init - Create a new Sqitch project

Synopsis

         sqitch init <project>
         sqitch init <project> --uri <uri>

Description

       This command creates an new Sqitch project -- basically a sqitch.conf file, a sqitch.plan file, and
       deploy, revert, and verify subdirectories.

       Running sqitch init in an existing project is safe. It will not overwrite things that are already there.

Options

       "--uri"
             sqitch init widgets --uri https://github.com/me/wigets

           Optional URI to associate with the project. If present, the URI will be written to the project plan
           and used for added uniqueness in hashed object IDs.

       "--engine"
             sqitch init widgets --engine pg

           Specifies the default database engine to use in the project. 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/>

       "--top-dir"
             sqitch init widgets --top-dir sql

           Specifies the top directory to use for the project. Typically contains the deployment plan file and
           the change script directories.

       "--plan-file"
             sqitch init widgets --plan-file my.plan

           Specifies the path to the deployment plan file. Defaults to "$top_dir/sqitch.plan".

       "--extension"
             sqitch init widgets --extension ddl

           Specifies the file name extension to use for change script file names.  Defaults to "sql".

       "--dir"
             sqitch init widgets --dir deploy=dep --dir revert=rev --dir verify=tst

           Sets the path to a script directory. May be specified multiple times.  Supported keys are:

           •   "deploy"

           •   "revert"

           •   "verify"

           •   "reworked"

           •   "reworked_deploy"

           •   "reworked_revert"

           •   "reworked_verify"

       "--target"
             sqitch init widgets --target db:pg:widgets

           Specifies the name or URI <https://github.com/theory/uri-db/> of the default target database. If
           specified as a name, the default URI for the target will be "db:$engine:".

       "--registry"
             sqitch init widgets --registry meta

           Specifies the name of the database object where Sqitch's state and history data is stored. Typically
           a schema name (as in PostgreSQL and Oracle) or a database name (as in SQLite and MySQL). Defaults to
           "sqitch".

       "--client"
             sqitch init widgets --client /usr/local/pgsql/bin/psql

           Specifies the path to the command-line client for the database engine.  Defaults to a client in the
           current path named appropriately for the specified engine.

Configuration

       The most important thing "sqitch init" does is create the project plan file, sqitch.conf. The options
       determine what gets written to the file:

       "--engine"
           Sets the "core.engine" configuration variable.

       "--top-dir"
           Sets the "core.top_dir" configuration variable.

       "--plan-file"
           Sets the "core.plan_file" configuration variable.

       "--extension"
           Sets the "core.extension" configuration variable.

       "--dir"
           Sets the following configuration variables:

           •   "deploy" sets "core.deploy_dir"

           •   "revert" sets "core.revert_dir"

           •   "verify" sets "core.verify_dir"

           •   "reworked" sets "core.reworked_dir"

           •   "reworked_deplpoy" sets "core.reworked_deploy_dir"

           •   "reworked_deplpoy" sets "core.reworked_revert_dir"

           •   "reworked_deplpoy" sets "core.reworked_verify_dir"

       "--target"
           Sets the "engine.$engine.target" configuration variable if "--engine" is also passed and, if it's a
           target name, "target.$target.uri"

       "--registry"
           Sets the "engine.$engine.registry" configuration variable if "--engine" is also passed.

       "--client"
           Sets the "engine.$engine.client" configuration variable if "--engine" is also passed.

       As a general rule, you likely won't need any of these options except for "--engine", since many commands
       need to know what engine to use, and specifying it on the command-line forever after would be annoying.

       These variables will only be written if their corresponding options are specified. Otherwise, core
       options get written as comments with user or system configuration settings, or, failing any values from
       those locations, from their default values. If no defaults are specified, they will still be written,
       commented out, with a bar "=" and no value. This allows one to know what sorts of things are available to
       edit.

Examples

       Start a new Sqitch project using the SQLite engine, setting the top directory for the project to sqlite:

         sqitch init --engine sqlite --top-dir sqlite

       Start a new Sqitch project using the PostgreSQL engine, setting the top directory to postgres, script
       extension to "ddl", reworked directory to "reworked" and a version-specific client:

         sqitch init --engine  pg \
                     --top-dir postgres \
                     --client  /opt/pgsql-9.1/bin/psql \
                     --extension ddl --dir reworked=reworked
