== DESCRIPTION:

This gem is based on Rails plugin 'css_dryer': http://github.com/airblade/css_dryer.
Unlike 'css_dryer', this one doesn't create any controllers and views.
Instead, it acts more like SASS, but uses css_dryer parser (which allows you to use completely
conventional css-syntax and write one-line css rules).

* Read 'install' section to find out how to use it with Rails or any other Ruby appplication.
* Read USAGE.markdown file to learn about css_dryer parser (copypasted from css_dryer README).

== REQUIREMENTS:

* ActiveResource gem

== INSTALL:

The following steps assume you're using a Rails application.
Adjust for using in other cases.

1) 

  sudo gem install cssdryer2
    
2) Put this is config/environments/development.rb:

  require 'css_dryer_2'
  
3) Go to rails application folder and run: 

  'script/generate cssdryer2'.

This will generate neccessary rake tasks. Step 2 is mandatory before that. 

4) In dev environment, to generate css on any changes in .ncss files, put this in ApplicationController:

  before_filter :ncss
  def ncss
    CssDryer2::FilesHandler.new(:settings => :rails).run if RAILS_ENV == 'development'
  end

You can also set custom directories for files, instead of using rails shortcut option:

  CssDryer2::FilesHandler.new(
    :source_path  => 'my_css_dir/ncss',
    :compile_path => 'my_css_dir',
    :tmp_path     => '/tmp',
    :force_compile => true
  )


5) While deploying Rails application to production, run rake task:

  rake ncss:compile

6) Now put your .ncss files in your 'public/stylesheets/ncss/' dir.
The compiler will put generated css files in 'public/stylesheets/' dir.


== HOW IT WORKS:

When you fire 'run' method, CssDryer2::FileHandler object checks if the .ncss files
changed (it stores their SHA1 in tmp dir). If they did, it recompiles them.

For Rails application it assumes that you store your .ncss files in 'public/stylesheets/ncss',
and it compiles .css files in 'public/stylesheets'.
You might want to add 'public/stylesheets/*.css' into your '.gitignore' file 

You can force reompile by providing the run method with':force_recompile => true' argument.
You can also recompile at any time by running 'rake ncss:compile'
