Pod::Simple::Methody.3perl

NAME

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

SYNOPSIS

  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.

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:

   $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.
