NAME

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

SYNOPSIS

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;

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.
