Path::Dispatcher::Declarative(3pm) User Contributed Perl Documentation Path::Dispatcher::Declarative(3pm) NAME
Path::Dispatcher::Declarative - sugary dispatcher SYNOPSIS
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: "; ... }; on score => sub { print "score: "; ... }; AUTHOR
