NAME

Path::Router - A tool for routing paths

SYNOPSIS

  my $router = Path::Router->new;
  
  $router->add_route('blog' => (
      defaults => {
          controller => 'blog',
          action     => 'index',
      }
  ));
  
  $router->add_route('blog/:year/:month/:day' => (
      defaults => {
          controller => 'blog',
          action     => 'show_date',
      },
      # validate with ...
      validations => {
          # ... raw-Regexp refs
          year       => qr/\d{4}/,
          # ... custom Moose types you created
          month      => 'NumericMonth', 
          # ... Moose anon-subtypes created inline
          day        => subtype('Int' => where { $_ <= 31 }),        
      }
  ));
  
  $router->add_route('blog/:action/?:id' => (
      defaults => {
          controller => 'blog',
      },
      validations => {
          action  => qr/\D+/,   
          id      => 'Int',  # also use plain Moose types too
      }
  ));
  
  # ... in your dispatcher
  
  my $deconstructed_path_hash = $router->match('/blog/edit/15');
  
  # ... in your code
  
  my $uri = $router->uri_for(
      controller => 'blog',
      action     => 'show_date',
      year       => 2006,
      month      => 10,
      day        => 5,
  );

DESCRIPTION

This module provides a way of deconstructing paths into parameters suitable for dispatching on. It also provides the inverse in that it will take a list of parameters, and construct an appropriate uri for it.

Reversable

This module places a high degree of importance on reversability. The value produced by a path match can be passed back in and you will get the same path you originally put in. The result of this is that it removes ambiguity and therefore reduces the number of possible mis-routings.

Verifyable

This module also provides additional tools you can use to test and verify the integrity of your router. These include:

An interactive shell in which you can test various paths and see the match it will return, and also test the reversability of that match.
A Test::Path::Router module which can be used in your applications test suite to easily verify the integrity of your paths.

Hey, wait, this is like RoR!

Yes, this is based on Ruby on Rails ActionController::Routing::Routes, however, it has one important difference.

It is in Perl :)
