padre::task::eval

Padre::Task::Eval(3pm)					User Contributed Perl Documentation				    Padre::Task::Eval(3pm)

NAME

       Padre::Task::Eval - Task for executing arbitrary code via a string eval

SYNOPSIS

	 my $task = Padre::Task::Eval->new(
	     prepare => '1 + 1',
	     run     => 'my $foo = sub { 2 + 3 }; $foo->();',
	     finish  => '$_[0]->{prepare}',
	 );

	 $task->prepare;
	 $task->run;
	 $task->finish;

DESCRIPTION

       Padre::Task::Eval is a stub class used to implement testing and other miscellaneous functionality.

       It takes three named string parameters matching each of the three execution phases. When each phase of the task is run, the string will be
       eval'ed and the result will be stored in the same has key as the source string.

       If the key does not exist at all, nothing will be executed for that phase.

       Regardless of the execution result (or the non-execution of the phase) each phase will always return true. However, if the string eval
       throws an exception it will escape the task object (although when run properly inside of a task handle it should be caught by the handle).

METHODS

       This class contains now additional methods beyond the defaults provided by the Padre::Task API.
