NAME ^

Router::Dumb::Helper::FileMapper - something to build routes out of a dumb tree of files

VERSION ^

version 0.003

OVERVIEW ^

The FileMapper helper looks over a tree of files and adds routes to a Router::Dumb object based on those files.

For example, imagine the following file hierarchy:

  templates
  templates/pages
  templates/pages/help
  templates/pages/images
  templates/pages/images/INDEX
  templates/pages/INDEX
  templates/pages/legal
  templates/pages/legal/privacy
  templates/pages/legal/tos

With the following code...

  use Path::Class qw(dir);

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

  Router::Dumb::Helper::FileMapper->new({
    root => 'templates/pages',
    target_munger => sub {
      my ($self, $filename) = @_;
      dir('pages')->file( file($filename)->relative($self->root) )
                  ->stringify;
    },
  })->add_routes_to($r);

...the router will have a route so that:

  $r->route( '/legal/privacy' )->target eq 'pages/legal/privacy';

These routes never have placeholders, and if files in the tree have colons at the beginning of their names, an exception will be thrown. Similarly, slurpy routes will never be added, and files named * are forbidden.

Files named INDEX are special: they cause a route for the directory's name to exist.

ATTRIBUTES ^

root

This is the name of the root directory to scan when adding routes.

target_munger

This attribute (which has a default no-op value) must be a coderef. It is called like a method, with the first non-self argument being the file responsible for the route. It should return the target for the route to be added.

parts_munger

This attribute (which has a default no-op value) must be a coderef. It is called like a method, with the first non-self argument being an arrayref of the path components of the file responsible for the route. It should return the parts for the route to be added.

METHODS ^

add_routes_to

  $helper->add_routes_to( $router, \%arg );

This message tells the helper to scan its directory root and add routes to the given router. The helper can be used over and over.

Valid arguments are:

  ignore_conflicts - if true, trying adding an existing route will be ignored,
                     rather than fail
