SYNOPSIS

package MyApp::Controller::Browser::Example;
use Moose;
BEGIN { extends 'Catalyst::Controller::DirectoryDispatch' }

__PACKAGE__->config(
    action => { setup => { Chained => '/browser/base', PathPart => 'mydir' } },
    root     => '/home/andy',
    filter     => qr{^\.|.conf$},
    data_root  => 'data',
    full_paths => 1,
);

DESCRIPTION

Provides a simple configuration based controller for listing local system directories and dispatching them as URLs.

Example Usage

If you created the controller at http://localhost/mydir and set root to '/home/user1' then browsing to the controller might give the following output:

{
    "success":true,
    "data":[
        "file1",
        "file2",
        "dir1",
        "dir2"
    ],
}

You could then point your browser to http://localhost/mydir/dir1 to get a directory listing of the folder '/home/user1/dir1' and so on...

Changing Views

The default view for DirectoryDispatch serializes the file list as JSON but it's easy to change it to whatever view you'd like.

__PACKAGE__->config(
    'default'   => 'text/html',
    'map'       => {
        'text/html' => [ 'View', 'TT' ],
    }
);

Then in your template...

[% FOREACH node IN response.data %]
[% node %]
[% END %]

Post Processing

If you need to process the files in anyway before they're passed to the view you can override process_files in your controller.

sub process_files {
    my ($self, $c, $files) = @_;

    foreach my $file ( @$files ) {
        # Modify $file
    }

    return $files;
}

This is the last thing that happens before the list of files are passed on to the view. $files is sent in as an ArrayRef[Str] but you are free to return any thing you want as long as the serializer you're using can handle it.

CONFIGURATION

root

is: ro, isa: Str

The folder that will be listed when accessing the controller (default '/').

filter

is: ro, isa: RegexpRef

A regular expression that will remove matching files or folders from the directory listing (default: undef).

data_root

is: ro, isa: Str

The name of the key inside $c->stash->{response} where the directory listing will be stored (default: data).

full_paths

is: ro, isa: Bool

Returns full paths for the directory listing rather than just the names (default: 0).

THANKS

The design for this module was heavly influenced by the fantastic Catalyst::Controller::DBIC::API.
