Padre::Task::PPI(3)

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

SYNOPSIS
  package Padre::Task::MyFancyTest;

  use strict;
  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;

DESCRIPTION
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.

SEE ALSO
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.
