NAME ^

Path::Router - A tool for routing paths

VERSION ^

version 0.12

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:

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.

DEBUGGING ^

You can turn on the verbose debug logging with the PATH_ROUTER_DEBUG environment variable.
