Padre::Task::PPI(3pm) User Contributed Perl Documentation Padre::Task::PPI(3pm) 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. AUTHOR
