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.
