Padre::Task::SyntaxChecker(3) Generic syntax-checking background processing task


package Padre::Task::SyntaxChecker::MyLanguage;
use base 'Padre::Task::SyntaxChecker';

sub run {
my $self = shift;
my $doc_text = $self->{text};
# black magic here
$self->{syntax_check} = ...;
return 1;


# elsewhere:

# by default, the text of the current document
# will be fetched as will the document's notebook page.
my $task = Padre::Task::SyntaxChecker::MyLanguage->new();

my $task2 = Padre::Task::SyntaxChecker::MyLanguage->new(
text => Padre::Current->document->text_get,
editor => Padre::Current->editor,


This is a base class for all tasks that need to do expensive syntax checking in a background task.

You can either let "Padre::Task::SyntaxChecker" fetch the Perl code for parsing from the current document or specify it as the ""text"" parameter to the constructor.

To create a syntax checker for a given document type "Foo", you create a subclass "Padre::Task::SyntaxChecker::Foo" and implement the "run" method which uses the "$self->{text}" attribute of the task object for its nefarious syntax checking purposes and then stores the result in the "$self->{syntax_check}" attribute of the object. The result should be a data structure of the form defined in the documentation of the "Padre::Document::check_syntax" method. See Padre::Document.

This base class implements all logic necessary to update the GUI with the syntax check results in a "finish()" hook. If you want to implement your own "finish()", make sure to call "$self->SUPER::finish" for this reason.
