Name ^

App::Sqitch::Target - Sqitch deployment target

Synopsis ^

  my $plan = App::Sqitch::Target->new(
      sqitch => $sqitch,
      name   => 'development',
  );
  $target->engine->deploy;

Description ^

App::Sqitch::Target provides collects, in one place, the engine, plan, and file locations required to carry out Sqitch commands. All commands should instantiate a target to work with the plan or database.

Interface ^

Constructors

new

  my $target = App::Sqitch::Target->new( sqitch => $sqitch );

Instantiates and returns an App::Sqitch::Target object. The most important parameters are sqitch, name, and uri. The constructor tries really hard to figure out the proper name and URI during construction. If the uri parameter is passed, this is straight-forward: if no name is passed, name will be set to the stringified format of the URI (minus the password, if present).

Otherwise, when no URI is passed, the name and URI are determined by taking the following steps:

As a general rule, then, pass either a target name or URI string in the name parameter, and Sqitch will do its best to find all the relevant target information. And if there is no name or URI, it will try to construct a reasonable default from the command-line options or engine configuration.

all_targets

Returns a list of all the targets defined by the local Sqitch configuration file. Done by examining the configuration object to find all defined targets and engines, as well as the default "core" target. Duplicates are removed and the list returned. This method takes two parameters:

Accessors

sqitch

  my $sqitch = $target->sqitch;

Returns the App::Sqitch object that instantiated the target.

name

target

  my $name = $target->name;
  $name = $target->target;

The name of the target. If there was no name specified, the URI will be used (minus the password, if there is one).

uri

  my $uri = $target->uri;

The URI::db object encapsulating the database connection information.

username

  my $username = $target->username;

Returns the target username, if any. The username is looked up from the URI.

password

  my $password = $target->password;

Returns the target password, if any. The password is looked up from the URI or the $SQITCH_PASSWORD environment variable.

engine

  my $engine = $target->engine;

A App::Sqitch::Engine object to use for database interactions with the target.

registry

  my $registry = $target->registry;

The name of the registry used by the database. The value comes from one of these options, searched in this order:

client

  my $client = $target->client;

Path to the engine command-line client. The value comes from one of these options, searched in this order:

top_dir

  my $top_dir = $target->top_dir;

The path to the top directory of the project. This directory generally contains the plan file and subdirectories for deploy, revert, and verify scripts. The value comes from one of these options, searched in this order:

plan_file

  my $plan_file = $target->plan_file;

The path to the plan file. The value comes from one of these options, searched in this order:

deploy_dir

  my $deploy_dir = $target->deploy_dir;

The path to the deploy directory of the project. This directory contains all of the deploy scripts referenced by changes in the plan_file. The value comes from one of these options, searched in this order:

revert_dir

  my $revert_dir = $target->revert_dir;

The path to the revert directory of the project. This directory contains all of the revert scripts referenced by changes the plan_file. The value comes from one of these options, searched in this order:

verify_dir

  my $verify_dir = $target->verify_dir;

The path to the verify directory of the project. This directory contains all of the verify scripts referenced by changes in the plan_file. The value comes from one of these options, searched in this order:

reworked_dir

  my $reworked_dir = $target->reworked_dir;

The path to the reworked directory of the project. This directory contains subdirectories for reworked deploy, revert, and verify scripts. The value comes from one of these options, searched in this order:

reworked_deploy_dir

  my $reworked_deploy_dir = $target->reworked_deploy_dir;

The path to the reworked deploy directory of the project. This directory contains all of the reworked deploy scripts referenced by changes in the plan_file. The value comes from one of these options, searched in this order:

reworked_revert_dir

  my $reworked_revert_dir = $target->reworked_revert_dir;

The path to the reworked revert directory of the project. This directory contains all of the reworked revert scripts referenced by changes the plan_file. The value comes from one of these options, searched in this order:

reworked_verify_dir

  my $reworked_verify_dir = $target->reworked_verify_dir;

The path to the reworked verify directory of the project. This directory contains all of the reworked verify scripts referenced by changes in the plan_file. The value comes from one of these options, searched in this order:

extension

  my $extension = $target->extension;

The file name extension to append to change names to create script file names. The value comes from one of these options, searched in this order:

engine_key

  my $key = $target->engine_key;

The key defining which engine to use. This value defines the class loaded by engine. Convenience method for $target->uri->canonical_engine.

dsn

  my $dsn = $target->dsn;

The DSN to use when connecting to the target via the DBI. Convenience method for $target->uri->dbi_dsn.

username

  my $username = $target->username;

The username to use when connecting to the target via the DBI. Convenience method for $target->uri->user.

password
