Sass & CoffeeScript automated compiling and minifying with Guard

README.md

Sass & CoffeeScript automated compiling and minifying with Guard:

1. Install RVM http://beginrescueend.com/rvm/install/

2. Install Ruby 1.9.2: $ rvm install ruby-1.9.2-p290

3. Create a gemset for 'yourapplication': $ rvm gemset create yourapplication

4. Switch to this gemset $ rvm gemset use yourapplication

5. Install bundler : $ gem install bundler

6. $ bundle install (this should take a while…)

7. Install Juicer needed files:

   $ juicer install yui_compressor
   $ juicer install closure_compiler
   $ juicer install jslint

8. $ guard or $ bundle exec guard

Bonus: install LiveReload, for Chrome or for Safari

Default directories for your assets:

Sources:

• assets/sass/
• assets/coffeescripts

Compiled files

• javascripts/*.js
• stylesheets/*.css

Only application.css and application.js will be minified. You can change that in Guardfile.

compass.rb

# Require any additional compass plugins here.

# Set this to the root of your project when deployed:
http_path = "/"
css_dir = "stylesheets"
sass_dir = "assets/sass"
images_dir = "images"
javascripts_dir = "javascripts"

# You can select your preferred output style here (can be overridden via the command line):
output_style = :nested

# To enable relative paths to assets via compass helper functions. Uncomment:
# relative_assets = true

# To disable debugging comments that display the original location of your selectors. Uncomment:
# line_comments = false


# If you prefer the indented syntax, you might want to regenerate this
# project again passing --syntax sass, or you can uncomment this:
# preferred_syntax = :sass
# and then run:
# sass-convert -R --from scss --to sass sass scss && rm -rf sass && mv scss sass
