Constructors

  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

  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.

  my $engine = $target->engine;
