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";
             ...
         };
