=head1 NAME

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

=head1 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.

=head1 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 L<Pod::Simple> and inherits all
its methods.)

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

=head1 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.
