README.md

What?

Guard wrapper for the Uglifier gem.

Installation

Add to your Gemfile:

gem 'guard-uglify'

Or install the gem manually:

$ gem install guard-uglify

Then add the default Guard::Uglify template to your Guardfile by running:

$ guard init uglify

Which will add this to your Guardfile:

###
# Sample Guardfile block for Guard::Uglify
#
# :input        - input file to compress
# :output       - file to write compressed output to
# :run_at_start - compressed input file when guard starts
# :uglifier     - options to be passed to the uglifier gem
###
guard "uglify", :input => "app/assets/javascripts/application.js", :output => "public/javascripts/application.js"

Usage

Adjust the paths, and set the options to your liking. The :uglifier option contains options that will be passed to the Uglifier gem, which you can find here. When run, the input file will be compressed and then written to the output file. If you are using this with my guard-sprocketize gem, place the above guard block after the sprockets block in your Guardfile.

The default configuration should work for a Rails 3 project with a directory structure like this:

|-- app
|   |-- controllers
|   |-- assets
|   |   |-- sass
|   |   `-- javascripts
|   |       `-- application.js # Your source javascript file
|   |-- helpers
|   |-- mailers
|   |-- models
|   `-- views
|       `-- layouts
|-- config
|   |-- environments
|   |-- initializers
|   `-- locales
|-- db
|-- doc
|-- lib
|   `-- tasks
...
|-- public
    `-- javascripts
        `-- application.js # Compressed output file
... etc.

TODO

  • Write better tests
