SYNOPSIS

10
11         use strict;
12         use base 'Padre::Task::PPI';
13
14         # Will be called after ppi-parsing:
15         sub process {
16             my $self   = shift;
17             my $ppi    = shift or return;
18             my $result = ...expensive_calculation_using_ppi...
19             $self->{result} = $result;
20             return;
21         }
22
23         1;
24
25         # elsewhere:
26
27         Padre::Task::MyFancyTest->new(
28             text => 'parse-this!',
29         )->schedule;

DESCRIPTION

32       This is a base class for all tasks that need to do expensive
33       calculations using PPI. The class will setup a PPI::Document object
34       from a given piece of code and then call the "process_ppi" method on
35       the task object and pass the PPI::Document as first argument.
36
37       You can either let "Padre::Task::PPI" fetch the Perl code for parsing
38       from the current document or specify it as the ""text"" parameter to
39       the constructor.
40
41       Note: If you don't supply the document text and there is no currently
42       open document to fetch it from, "new()" will simply return the empty
43       list instead of a "Padre::Task::PPI" object.
44

SEE ALSO

46       This class inherits from "Padre::Task" and its instances can be
47       scheduled using "Padre::TaskManager".
48
49       The transfer of the objects to and from the worker threads is
50       implemented with Storable.
