man Mason::Plugin::RouterSimple (3): Specify routes for page components

VERSION

version 0.07

SYNOPSIS

In a top-level component '/archives.mc':

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

DESCRIPTION

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.

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

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 '/site.mc',

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.
