NAME
Padre::Task::PPI - Generic PPI background processing taskSYNOPSIS
package Padre::Task::PPI::MyFancyTest; use base 'Padre::Task::PPI'; # will be called after ppi-parsing: sub process_ppi { my $self = shift; my $ppi = shift or return; my $result = ...expensive_calculation_using_ppi... $self->{result} = $result; return(); }, sub finish { my $self = shift; my $result = $self->{result}; # update GUI here... }; 1; # elsewhere: # by default, the text of the current document # will be fetched. my $task = Padre::Task::PPI::MyFancyTest->new(); $task->schedule; my $task2 = Padre::Task::PPI::MyFancyTest->new( text => 'parse-this!', ); $task2->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.
