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


 require 5;
 use strict;
 package SomePodFormatter;
 use base qw(Pod::Simple::Methody);

 sub handle_text {
   my($self, $text) = @_;

 sub start_head1 {
   my($self, $attrs) = @_;
 sub end_head1 {
   my($self) = @_;

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


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 the Pod::Simple manpage and inherits all its methods.)

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


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

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

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

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