Padre::Task::PPI - Generic PPI background processing task

  package Padre::Task::MyFancyTest;

  use base 'Padre::Task::PPI';

  # Will be called after ppi-parsing:
  sub process {
      my $self   = shift;
      my $ppi    = shift or return;
      my $result = ...expensive_calculation_using_ppi...
      $self->{result} = $result;
      return;
  }

  1;

  # elsewhere:

  Padre::Task::MyFancyTest->new(
      text => 'parse-this!',
  )->schedule;

This is a base class for all tasks that need to do expensive calculations using PPI. The class will setup a PPI::Document object from a given piece of code and then call the process_ppi method on the task object and pass the PPI::Document as first argument.

You can either let Padre::Task::PPI fetch the Perl code for parsing from the current document or specify it as the "text" parameter to the constructor.

Note: If you don't supply the document text and there is no currently open document to fetch it from, new() will simply return the empty list instead of a Padre::Task::PPI object.

This class inherits from Padre::Task and its instances can be scheduled using Padre::TaskManager.

The transfer of the objects to and from the worker threads is implemented with Storable.
