+# Guard::RailsAssets
+
+
+Guard::RailsAssets compiles all the assets in Rails 3.1 application automatically when files are modified.
+
+Tested on MRI Ruby 1.9.2 (please report if it works on your platform).
+Currently only POSIX system is supported. Sorry Windows guys :(
+
+If you have any questions please contact me [@dnagir](http://www.ApproachE.com).
+
+## Install
+
+Please be sure to have [Guard](https://github.com/guard/guard) installed.
+
+Install the gem:
+
+Add it to your `Gemfile`, preferably inside the test and development group:
+
+```ruby
+gem 'guard-rails-assets'
+```
+
+Add guard definition to your `Guardfile` by running:
+
+```bash
+$ guard init rails-assets
+```
+
+## Rails 3.1
+
+The Rails 3.1 is a mandatory requirement, but is not enforeced via dependencies for now.
+The reason is that the assets are currently compiled via command line and thus this guard does not
+explicitly depend on Rails.
+
+Good thing about it is that assets will always be same as produced by Rails.
+Bad thing is that it is pretty slow (~10 seconds) because it starts Rails from ground zero.
+
+## Rails Assets Pipeline
+
+The convention used in this guard are:
+
+- assets prefix is set to 'assets' meaning that all assets are compiled in to `public/assets` folder;
+- the assets folder is disposable and can be cleared out.
+
+If the conventions above are not valid for you then perhaps you'd better submit a patch.
+
+## Guardfile and Options
+
+In addition to the standard configuration, this Guard has options to specify when exacly to precompile assets.
+
+- `:start` - compile assets when the guard starts (default)
+- `:reload` - compile assets when the guard quites (Ctrl-C) (not enabled)
+- `:all` - compile assets when running all the guard (Ctrl-/) (default)
+- `:change` - compile assets when watched files change (default)
+
+For example:
+
+
+```ruby
+# compile ONLY when something changes
+guard 'rails-assets', :run_on => :change do
+  watch(%r{^app/assets/.+$})
+end
+
+# compile when something changes and when starting
+guard 'rails-assets', :run_on => [:start, :change] do
+  watch(%r{^app/assets/.+$})
+end
+
+# This is the default behaviour
+guard 'rails-assets', :run_on => [:start, :change, :all] do
+  watch(%r{^app/assets/.+$})
+end
+```
+
