6 Module::Starter::Plugin -- how Module::Starter plugins work
7
9 This document is a guide to writing plugins for Module::Starter.
10 Currently, as is evident, it isn't very comprehensive. It should
11 provide enough information for writing effective plugins, though.
12 After all, Module::Starter's guts are nice and simple.
13
14 "Module::Starter->import"
15 Module::Starter provides an import method, the arguments to which are
16 plugins, in the order in which they should be loaded. If no plugins
17 are given, Module::Starter::Simple (and only Module::Starter::Simple)
18 is loaded.
19
20 By default, the given modules are required and arranged in an is-a
21 chain. That is, Module::Starter subclasses the last plugin given,
22 which subclasses the second-to-last, up to the first plugin given,
23 which is the base class. If a plugin provides a "load_plugins" method,
24 however, the remaining plugins to be loaded are passed to that method,
25 which is responsible for loading the rest of the plugins.
26
27 This architecture suggests two kinds of plugins:
28
29 engine plugins
30 An engine is a plugin that stands alone, implementing the public
31 "create_distro" method and all the functionality required to carry out
32 that implementation. The only engine included with Module::Starter is
33 Module::Starter::Simple, and I'm not sure any more will be seen in the
34 wild any time soon.
35
36 plain old plugins
37 Other plugins are designed to subclass an engine and alter its
38 behavior, just as a normal subclass alters its parent class's. These
39 plugins may add features to Module::Starter engines, or may just
40 provide general APIs for other plugins to exploit (like
41 Module::Starter::Plugin::Template.)
42
43 The template plugin is a simple example of a plugin that alters an
44 engine to accept further plugins. Other plugins like template will
45 probably be written in the near future, and plugins that exploit the
46 API provided by Module::Starter::Plugin::Template will be available on
47 the CPAN.
