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 Ω- 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.

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.
