NAME

Router::Dumb - yet another dumb path router for URLs

VERSION

version 0.005

SYNOPSIS

  my $r = Router::Dumb->new;

  $r->add_route(
    Router::Dumb::Route->new({
      parts       => [ qw(group :group uid :uid) ],
      target      => 'pants',
      constraints => {
        group => find_type_constraint('Int'),
      },
    }),
  );

  my $match = $r->route( '/group/123/uid/321' );
  
  # $match->target  returns 'pants'
  # $match->matches returns (group => 123, uid => 321)

DESCRIPTION

Router::Dumb provides a pretty dumb router. You can add routes and then ask how to route a given path string.

Routes have a path. A path is an arrayref of names. Names that start with a colon are placeholders. Everything else is a literal. Literals pieces must appear, literally, in the string being routed. A placeholder can be satisfied by any value, as long as it satisfies the placeholder's constraint. If there's no constraint, any value works.

The special part * can be used to mean "...then capture everything else into the placeholder named REST."

Most of the time, you won't be calling add_route, but using some other helper to figure out routes to add for you. Router::Dumb ships with Router::Dumb::Helper::FileMapper and Router::Dumb::Helper::RouteFile.

METHODS

add_route

  $router->add_route(
    Router::Dumb::Route->new({
      parts  => [ qw( the :path parts ) ],
      target => 'target-string',
      constraints => {
        path => $moose_tc,
      },
    })
  );

This method adds a new route to the router.

add_route_unless_exists

  $router->add_route_unless_exists(
    Router::Dumb::Route->new({
      parts  => [ qw( the :path parts ) ],
      target => 'target-string',
      ...
    })
  );

This method adds a new route to the router unless it would conflict, in which case it does nothing.

route

  my $match_or_undef = $router->route( $str );

If the given string can be routed to a match, the match is returned. If not, the method returns false.

The string must begin with a /.

ordered_routes

  my @routes = $router->ordered_routes;

This method returns the router's routes, in the order that they will be checked. You probably do not want to use this method unless you really know what you're doing.
