App::File and Directory to support index.html

[miyagawa]

From Larry Marso -

Is it possible to coax any of Plack's static modules to automatically
serve the index.html a directory level, when a browser is called on
that directory?

In other words, how can I get a call to http://site/static/blog
to serve up http://site/static/blog/index.html ???

Standard Plack::App::File (or Directory) and Plack::Middleware::Static
don't seem to do that.

Best I could come up with was the following hack, which only works for
one specified directory. Is there a solution of general applicability?

my $app3 = Plack::App::File->new( file => "/var/www/static/site/blog/index.html")->to_app;
builder {
enable "Plack::Middleware::Static", path => qr{^/blog/.+}, root => '/var/www/static/site/';
mount "/blog" => $app3;
}
}

and so on.

More fun with regex. The following seems to serve a static directory (URI) as directory/index.html, where directory is defined as call without "."

enable "Plack::Middleware::Static",
    path => sub { s!(^/blog(?:/[^.]*)?/?+$)!${1}/index.html! },
    root => '/var/www/static/site/';
enable "Plack::Middleware::Static",
    path => qr{^/blog/.+}, 
    root => '/var/www/static/site/';

We'd love to solve this by writing a piece of middleware that wraps ::File (or ::Directory) so that we can actually make it work with non file based backend as well, but haven't figured out how to do so effectively.

https://metacpan.org/release/LLAP/Plack-Middleware-DirIndex-0.01 <- this exists, doesn't try to do anything clever other than add the dir_index if the PATH_INFO ends in /

Patches for smarter stuff welcome, but scratches my itch for now.

DirIndex is working for me, and there are no recent comments --- can this be closed?
