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.
