SYNOPSIS

         my $router = Path::Router->new;

         $router->add_route('blog' => (
             defaults => {
                 controller => 'blog',
                 action     => 'index',
             },
             # you can provide a fixed "target"
             # for a match as well, this can be
             # anything you want it to be ...
             target => My::App->get_controller('blog')->get_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
             }
         ));

         # even include other routers
         $router->include_router( 'polls/' => $another_router );

         # ... in your dispatcher

         # returns a Path::Router::Route::Match object
         my $match = $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.

METHODS

       new
       add_route ($path, ?%options)
           Adds a new route to the end of the routes list.

       insert_route ($path, %options)
           Adds a new route to the routes list. You may specify an "at" parameter, which would
           indicate the position where you want to insert your newly created route. The "at"
           parameter is the "index" position in the list, so it starts at 0.

           Examples:

               # You have more than three paths, insert a new route at
               # the 4th item
               $router->insert_route($path => (
                   at => 3, %options
               ));

               # If you have less items than the index, then it's the same as
               # as add_route -- it's just appended to the end of the list
               $router->insert_route($path => (
                   at => 1_000_000, %options
               ));

               # If you want to prepend, omit "at", or specify 0
               $router->insert_Route($path => (
                   at => 0, %options
               ));

       include_router ( $path, $other_router )
           These extracts all the route from $other_router and includes them into the invocant
           router and prepends $path to all their paths.

           It should be noted that this does not do any kind of redispatch to the $other_router,
           it actually extracts all the paths from $other_router and inserts them into the
           invocant router. This means any changes to $other_router after inclusion will not be
           reflected in the invocant.

       routes
       match ($path)
           Return a Path::Router::Route::Match object for the first route that matches the given
           $path, or "undef" if no routes match.

       uri_for (%path_descriptor)
           Find the path that, when passed to "$router->match", would produce the given
           arguments.  Returns the path without any leading "/".  Returns "undef" if no routes
           match.

       route_class ($classname)
           The class to use for routes.  Defaults to Path::Router::Route.
