Template::Plugin::Heritable 0.02

Template::Plugin::Heritable is a Perl module with OO dispatching and inheritance for templates.

SYNOPSIS

[% USE Heritable %]

[%# searches providers for a "view" template method on
class (which should be a metamodel object, eg
someobj.meta in Perl 6) %]
[% Heritable.include(class, "view", { self = object }) %]

[%# return list of paths it would look %]
[% paths = Heritable.dispatch_paths(class, "view") %]

[%# if you dont have the class of the object handy, then
use invoke instead %]
[% Heritable.invoke(object, "method", { self = object } %]

[%# call the next method in the inheritance tree from
inside a template method %]
[% next_template() %]

Template::Plugin::Heritable provides support for selecting an appropriate template based on the class of an object. It is also possible to call the next template in the inheritance heirarchy/chain.

This provides a form of inheritance for template display.

The core of this is the template dispatch mechanism, which deals in terms of a suitable metamodel class. The module currently deals in the following metamodels; but no doubt you could fool it with modules which encapsulate other metamodels (such as Perl 5, NEXT, Class::C3, DBIx::Class::Schema, etc) with minimal effort by conforming to one of their APIs.
