Path::Router - A tool for routing paths
version 0.15
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, );
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.
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.
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.
Adds a new route to the end of the routes list.
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.
at
index
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 ));
These extracts all the route from $other_router and includes them into the invocant router and prepends $path to all their paths.
$other_router
$path
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.
Return a Path::Router::Route::Match object for the first route that matches the given $path, or undef if no routes match.
undef
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.
$router->match
/
The class to use for routes. Defaults to Path::Router::Route.
You can turn on the verbose debug logging with the PATH_ROUTER_DEBUG environment variable.
PATH_ROUTER_DEBUG
All complex software has bugs lurking in it, and this module is no exception. If you find a bug please either email me, or add the bug to cpan-RT.
