Mason::Plugin::RouterSimple - Specify routes for page components


version 0.07


In a top-level component '/':

    route ":section/{year:[0-9]{4}}/{month:[0-9]{2}}";

    Archives for <b><% $.section %></b>
    For the month of <% $.month %>/<% $.year %>

then /archives/news/2010/02 outputs

    Archives for <b>news</b>
    For the month of 2010/02


See Mason::Manual::RequestDispatch for background on how request paths get mapped to page components.

This plugin allows you to parse $m->path_info (the remainder of the top-level path) using Router::Simple routes.

It can be used whenever $m->path_info is set, i.e. with a dhandler or with a partial path.

Use the route keyword to declare routes in a <%class> block. Like Router::Simple::connect, route takes a string/regex pattern and a destination hashref; the latter defaults to {} if omitted. e.g.

    route "wiki/:page", { action => "wiki" };
    route "download/*.*", { action => "download" };
    route "blog/{year:[0-9]+}/{month:[0-9]{2}}";

This plugin overrides the default allow_path_info to return true for any component that declares at least one route. For components that do not declare a route, you will need to override allow_path_info as usual.

Any named captured arguments, including splat, are placed in component attributes, which are automatically declared (as standard read-write attributes) if you do not otherwise declare them.

If you specify more than one route in a component, they will be tried in turn, with the first matching route taking precedence.

If none of the routes match, the request will be declined; in a web context this generally means a 404.

e.g. Given the route declarations above in a component named '/',

  • The URL /site/wiki/HomePage will set $.action = "wiki" and $.page = "HomePage".

  • The URL /site/download/ping.mp3 will set $.action = "download" and $.splat = ['ping', 'mp3'].

  • The URL /site/blog/2010/02 will set $.year = "2010" and $.month = "02".

  • The URLs /site/other and /site/blog/10/02 will result in a decline/404.
