Router::Dumb::Helper::FileMapper - something to build routes out of a dumb tree of files
version 0.006
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.
This library should run on perls released even a long time ago. It should work on any version of perl released in the last five years.
Although it may work on older versions of perl, no guarantee is made that the minimum required version will not be increased. The version may be increased for any reason, and there is no promise that patches will be accepted to lower the minimum required perl.
This is the name of the root directory to scan when adding routes.
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.
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.
$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
