DESCRIPTION

This plugin role provides a simple wrapper mechanism around the Data::Section::Pluggable method add_format, making it an appropriate way to add such recipes to CPAN.

CONSTRUCTOR

new

my $class->new(%args);  # optional

If a constructor new is provided, it will be called when the plugin is added to create an instance of the plugin. The methods below will be called as instance methods. Otherwise the methods will be called as class methods.

METHODS

All methods are to be implemented by your class.

extensions

my @extensions = $plugin->extensions;
my \@extensions = $plugin->extensions;

Returns a list or array reference of filename extensions the plugin should apply to.

process_content

my $processed = $plugin->process_content($dps, $content);

Takes the Data::Section::Pluggable instance and content and returns the process content.
