h1. Hassle

Making "SASS":http://sass-lang.com/ less of a hassle on read only filesystems. (like "Heroku":http://heroku.com)

IMPORTANT: This is for rails 3. If you want hassle for rails 2, then you should use "the original one":http://github.com/pedro/hassle

h2. Install

Get it from "Gemcutter.":http://gemcutter.org

gem install hassle -s http://gemcutter.org

h2. Usage

By default, SASS compiles CSS into the @public/@ directory. On platforms like Heroku, "this won't work.":http://docs.heroku.com/constraints#read-only-filesystem Instead, Hassle compiles the SASS for you into @tmp/@ and serves it up via a @Rack::Static@ middleware.

Hassle assumes a few basic things about your setup: There's going to be a @tmp/@ directory where it can write to, and @public/@ is where you store your css. A simple example:

$ tree
.
|-- config.ru
|-- public
|   `-- stylesheets
|       `-- sass
|           `-- application.sass
`-- tmp
    `-- hassle
        `-- stylesheets
            `-- application.css

With a basic SASS file in @public/stylesheets/sass/application.sass@, you can include it in your views with:

Hassle will look at the default sass directory (@public/stylesheets/sass@) and other input directories given in @Sass::Plugin.options[:template_location]@. CSS files are then compiled into @tmp/@ one directory higher than where you specified. Here's a small example of customization:

Sass::Plugin.options[:template_location] = "./public/css/templates"

And after Hassle runs...

$ tree
.
|-- config.ru
|-- public
|   `-- css
|       `-- templates
|           `-- screen.sass
`-- tmp
    `-- hassle
        `-- css
            `-- screen.css

Include this in your views with:

h2. Integration

Here's how to integrate it with your favorite web framework:

h3. Rails

For Rails: @script/plugin install git://github.com/Papipo/hassle@. Done. Once you're in production mode, Hassle will kick in and prepare your SASS for all to enjoy.

h3. Sinatra

Here's a sample config.ru that's "up and running.":http://hassle-sinatra.heroku.com

require 'sinatra'
require 'hassle'
require 'haml'

get '/' do
  haml < 'stylesheet', :href => "stylesheets/application.css"}
  %body
    %h1 Hassle!
EOF
end

use Hassle
run Sinatra::Application

And its wonderful SASS file:

$ cat public/stylesheets/sass/application.sass 
h1
  font-size: 11em
  color: purple
