package MyApp::Dispatcher; use Path::Dispatcher::Declarative -base; on score => sub { show_score() }; on ['wield', qr/^\w+$/] => sub { wield_weapon($2) }; rewrite qr/^inv/ => "display inventory"; under display => sub { on inventory => sub { show_inventory() }; on score => sub { show_score() }; }; package Interpreter; MyApp::Dispatcher->run($input);
DESCRIPTION
Jifty::Dispatcher rocks!KEYWORDS
dispatcher -> Dispatcher
Returns the Path::Dispatcher object for this class; the object that the sugar is modifying. This is useful for adding custom rules through the regular API, and inspection.dispatch path -> Dispatch
Invokes the dispatcher on the given path and returns a Path::Dispatcher::Dispatch object. Acts as a keyword within the same package; otherwise as a method (since these declarative dispatchers are supposed to be used by other packages).run path, args
Performs a dispatch then invokes the ``run'' in Path::Dispatcher::Dispatch method on it.on path => sub {}
Adds a rule to the dispatcher for the given path. The path may be:- a string
- This is taken to mean a single token; creates an Path::Dispatcher::Rule::Tokens rule.
- an array reference
- This is creates a Path::Dispatcher::Rule::Tokens rule.
- a regular expression
- This is creates a Path::Dispatcher::Rule::Regex rule.
- a code reference
- This is creates a Path::Dispatcher::Rule::CodeRef rule.
under path => sub {}
Creates a Path::Dispatcher::Rule::Under rule. The contents of the coderef should be nothing other ``on'' and "under" calls.then sub { }
Creates a Path::Dispatcher::Rule::Always rule that will continue on to the next rule via "next_rule"The only argument is a coderef that processes normally (like on).
NOTE: You *can* avoid running a following rule by using "last_rule".
An example:
under show => sub { then { print "Displaying "; }; on inventory => sub { print "inventory:\n"; ... }; on score => sub { print "score:\n"; ... };
