NAME ^

MojoX::DirectoryListing - show Apache-style directory listings in your Mojolicious app

VERSION ^

0.04

SYNOPSIS ^

    use Mojolicious;  # or Mojolicious::Lite;
    use MojoX::DirectoryListing;

    # serve a directory listing under your app's  public/  folder
    serve_directory_listing( '/data' );

    # serve a directory listing in a different location
    serve_directory_listing( '/more-data', '/path/to/other/directory' );

    # serve all subdirectories, too
    serve_directory_listing( '/data', recursive => 1 );

    # change the default display options
    serve_directory_listings( '/data', 'show-file-type' => 0, 'show-forbidden' => 1 );

DESCRIPTION ^

I ported a web application from CGI to Mojolicious. I was mostly pleased with the results, but one of the features I lost in the port was the ability to serve a directory listing. This module is an attempt to make that feature available in Mojolicious, and maybe even make it better.

Mojolicious serves static files under your app's public/ directory. To serve a whole directory under your public/ directory (say, public/data-files), you would call

    serve_directory_listings( '/data-files' );

Now a request to your app for /dara-files will display a listing of all the files under public/data-files .

To serve a directory listing for a directory that is not under your app's public directory, provide a second argument to serve_directory_listings. For example

    serve_directory_listings( '/research', 'public/files/research/public' );
    serve_directory_listings( '/log', '/var/log/system' );

EXPORT ^

This module exports the "serve_directory_listing" subroutine to the calling package.

SUBROUTINES/METHODS ^

serve_directory_listing

serve_directory_listing( $route, %options )

serve_directory_listing( $route, $path, %options )

Configures the Mojolicious app to serve directory listings for the specified path rom the specified route.

If $path is omitted, then the appropriate directory in your apps public directory will be listed. For example, the route /data/foo will serve a listing for your app's public/data/foo directory.

recognized options

The serve_directory_listing function recognizes several options that control the appearance and the behavior of the directory listing.

sort-column => N | M | S | T

Controls whether the files in a directory will be ordered by <N>ame, file <M>odification time, file <S>ize, or file <T>ype. The default is to order listings by name.

If a request includes the parameter C, it will override this setting for that request. This makes the behavior of this feature similar to the feature in Apache (see http://cpansearch.perl.org/src/MOB/MojoX-DirectoryListing-0.04/ for example [actually, this is an emulation of Apache-style directory listing in Plack)).

display-order => A | D

Controls whether the files will be listed (using the sort criteria from sort-column) in <A>scending or <D>escending order. The default is ascending order.

A request that includes the parameter O will override this setting for that request.

show-file-time => boolean

If true, the directory listing includes the modification time of each file listed. The default is true.

show-file-size => boolean

If true, the directory listing includes the size of each file listed. The default is true.

show-file-type => boolean

If true, the directory listing includes the MIME type of each file listed. The default is true.

show-forbidden => boolean

If true, the directory listing includes files that are not readable by the user running the web server. When such a file is listed, it will not include a link to the file. The default is false.

show-icon => boolean

If true, an icon appears to the left of every directory listing indicating the type of file. The default is false.

recursive => boolean

If true, invoke serve_directory_listing on all subdirectories of the directory being served. The default is false.

stylesheet => url
stylesheet => \$style-spec

A URL to specify a cascading stylesheet to be applied to the directory listing page, or reference to a scalar that holds style information (suitable for inserting into a pair of <style></style> tags in the output of this subroutine.

If you do wish to override the styles for the directory listing output, the selectors you want to define are:

.directory-listing

A class that is applied to <body>, <h1>, and <hr> elements on the directory listing output.

.directory-listing-link

A class that is applied to the <a> tag associated with each filename in the directory listing.

.directory-listing-header

A class that applies to the column headings (Name, Last Modified, Size, and Type columns) in the directory listing.

.directory-listing-row

A class that applies to a row in the directory listing. which may include a file name, the file's modification time, the file's size, and the file's type.

.directory-listing-name

A class that applies to a filename in the directory listing, but not "forbidden" files -- see .directory-listing-forbidden-name.

.directory-listing-forbidden-name

A class that applies to the filename for a "forbidden" file; that is, a file listing that the user is allowed to see for a file that he/she is not allowed to see. See "show-forbidden".

.directory-listing-time

A class that applies to the display of a file's last modification time in the directory listing.

.directory-listing-size

A class that applies to the display of a file's size in the directory listing.

.directory-listing-type

A class that applies to the display of a file's file type in the directory listing.

If not specified, the default style is the one used by the app-dirserve application (see "ACKNOWLEDGEMENTS").

header => string

Specify HTML code to be included at the top of the directory listing page. If the string contains the token __DIR__, it will be replaced with the path of the directory being requested.

If a header is not specified, the default header is

    <h1 class="directory-listing">Index of __DIR__</h1>
footer => string

Specify HTML code to be included at the bottom of the directory listing page. If the string contains the token __DIR__, it will b e replaced with the path of the directory being requested.

The default footer is the empty string.

set_public_app_dir( $path )

Tells MojoX::DirectoryListing which directory your app uses to serve static data. The default is ./public. The public app dir is used to map the route to an actual path when you don't supply a $path argument to "serve_directory_listing".
