google_closure_fabric 0.0.5

fabric module for simplifying google closure integration

# Installation

pip install google_closure_fabric

or for latest dev version:

pip install https://github.com/batsuev/google-closure-fabric/archive/develop.zip

# Boilerplate
You can create new project using gclosureboilerplate script. Sample:

mkdir my-project
cd my-project
gclosureboilerplate .
fab bootstrap
fab build
fab serve

Open http://localhost:8000/ and enjoy. Or http://localhost:8000/index.min.html for compiled version.
All changes in sources will rebuild automatically.

# Boilerplate project structure
* my-project/
* src/
* js/
* css/
* templates/
* dist/
* pages/
* libs-google/
* fabfile.py

`src/js` - folder with javascript source code.
`src/css` - css sources.
`src/templates` - soy templates.
`dist` - compiled output.
`pages` - html files.
`libs-google` - folder for all google libs.
`fabfile.py` - fabric file with all required tasks.

# Google Closure libraries and tools

Running `fab bootstrap` in project folder will install all libraries to `libs-google` folder.
plovr installation is disabled in this example.

That will be installed:
* Google Closure Stylesheets (http://code.google.com/p/closure-stylesheets/)
* Google Closure Templates (https://developers.google.com/closure/templates/)
* Google Closure Compiler (https://developers.google.com/closure/compiler/)
* Google Closure Library (https://developers.google.com/closure/library/)
* Plovr (http://plovr.com)
