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:

If there is no name, get the engine key from --engine or the core.engine configuration option. If no key can be determined, an exception will be thrown.
Use the key to look up the target name in the engine.$engine.target configuration option. If none is found, use db:$key:.
If the name contains a colon (:), assume it is also the value for the URI.
Otherwise, it should be the name of a configured target, so look for a URI in the target.$name.uri configuration option.

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:

sqitch

An App::Sqitch object. Required.
config

An App::Sqitch::Config object. If not passed, the object stored in the Sqitch object's config attribute will be used.

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;

`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;
