Padre::Task::PPI - Generic PPI background processing task
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;
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.
process_ppi
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.
Padre::Task::PPI
text
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.
new()
This class inherits from Padre::Task and its instances can be scheduled using Padre::TaskManager.
Padre::Task
Padre::TaskManager
The transfer of the objects to and from the worker threads is implemented with Storable.
