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.
