I put together a quick template engine for Dancer using Haml via Text::Haml. You know Haml, right?

Now you can do neat shit like this:

 set template => 'haml';

 get '/bazinga', sub {
        template 'bazinga' => {
                title => 'Bazinga!',
                content => 'Bazinga?',
        };
 };

Using:

 !!!
 %html{ : xmlns => "http://www.w3.org/1999/xhtml", :lang => "en", "xml:lang" => "en"}
   %head
     %title= title
   %body
     #content
       %strong= content

The dope thing about Text::Haml is that things like the Ruby interpolation will keep working.

Hurray! Go get it now.

Last week, or the one before that one, Alexis released Dancer 1.130 which represents a big refactoring of the Dancer core code, taking all optional modules away from it: Logging, session and template engines were splited into their respective non-core modules, etc. Additionally, two keyword features were added, header and prefix. I will showcase both in case you haven't heard the good word from them

header

The header keyword allows you to modify or alter the response headers by hand. That was a nice little feature that still hadn't been implemented. With header you can do nice little things like this:

get '/set/header' => sub {
  header 'X-Foo' => 'bar';
  "I'm a happy string." . "\n";
}

And this is what that very same code does:

~ $ curl -i http://0.0.0.0:3000/set/header
HTTP/1.0 200 OK
X-Foo: bar
Content-Type: text/html
X-Powered-By: Perl Dancer 1.130

I'm a happy string.

Also, header has a method synonym, headers, and you can use both indistinctly:

get '/some/crap', sub {
  headers 'X-Foo' => 'Bar',
    'X-Bar' => 'Foo';
}

And it will produce the result that you are expecting.

prefix

prefix is also interesting. It will indicate that the following route handlers' path patters defined for Dancer will be prepended with such prefix. So:

prefix '/user';
get '/home', sub { template 'user_home' };
get '/logout', sub { "bye!" };

So here we are instructing Dancer two route handlers that happen to be really pointing to "/user/home" and "/user/logout". In order to stop prefixing the route handlers' paths you just do:

prefix undef;

And continue with your un-prepended paths.
