SASS is being served uncompiled and uncompressed:

sinatra-assetpack is serving SASS in plain-text format, with no conversion or compression. I have arranged the assets differently than shown in the examples:

./app.rb
./config.ru
./Gemfile
./Gemfile.lock
./assets
./assets/css
./assets/css/style.sass
./assets/img
./assets/js
./assets/js/app.js

but I have also made changes to reflect the correct asset structure in app.rb:

class MyApp < Sinatra::Base
    enable :inline_templates
    register Sinatra::AssetPack
    assets do
        serve '/js', :from => 'assets/js'
        serve '/css', :from => 'assets/css'

        js :app, [
            '/js/app.js'
        ]

        css :app, [
            '/css/style.sass',
        ]

        js_compression :jsmin
        css_compression :sass
    end

    get '/' do
        haml :index
    end

end

__END__

    %head
        != css :app
    %body

        != js :app

And here's the output:

    <link rel='stylesheet' href='/css/style.sass' />

    <h1>Hello World!</h1>
