Pod::Simple::Methody

NAME

Pod::Simple::Methody -- turn Pod::Simple events into method calls

SYNOPSIS

  1. require 5;
  2. use strict;
  3. package SomePodFormatter;
  4. use base qw(Pod::Simple::Methody);
  5. sub handle_text {
  6. my($self, $text) = @_;
  7. ...
  8. }
  9. sub start_head1 {
  10. my($self, $attrs) = @_;
  11. ...
  12. }
  13. sub end_head1 {
  14. my($self) = @_;
  15. ...
  16. }

...and start_/end_ methods for whatever other events you want to catch.

DESCRIPTION

This class is of interest to people writing Pod formatters based on Pod::Simple.

This class (which is very small -- read the source) overrides Pod::Simple's _handle_element_start, _handle_text, and _handle_element_end methods so that parser events are turned into method calls. (Otherwise, this is a subclass of Pod::Simple and inherits all its methods.)

You can use this class as the base class for a Pod formatter/processor.

METHOD CALLING

When Pod::Simple sees a "=head1 Hi there", for example, it basically does this:

  1. $parser->_handle_element_start( "head1", \%attributes );
  2. $parser->_handle_text( "Hi there" );
  3. $parser->_handle_element_end( "head1" );

But if you subclass Pod::Simple::Methody, it will instead do this when it sees a "=head1 Hi there":

  1. $parser->start_head1( \%attributes ) if $parser->can('start_head1');
  2. $parser->handle_text( "Hi there" ) if $parser->can('handle_text');
  3. $parser->end_head1() if $parser->can('end_head1');

If Pod::Simple sends an event where the element name has a dash, period, or colon, the corresponding method name will have a underscore in its place. For example, "foo.bar:baz" becomes start_foo_bar_baz and end_foo_bar_baz.

See the source for Pod::Simple::Text for an example of using this class.
