DESCRIPTION

This package allows you to compress your javascript code by using the online service of Closure Compiler offered by Google via a REST API. See http://closure-compiler.appspot.com/ for further information.

MOTIVATION

Needed a package to encapsulate a coherent API for a future Javascript::Minifier::Any package.

ADVANTAGES

Gives you access to the closure compression algo with an unified API.

SUBROUTINES/METHODS

minifier(input= scalar,compilation_level=>scalar,output_info=>scalar,output_format=>scalar)>

Takes an hash that should contain input as a key and a javascript code a value or an url starting by http://. If you do not supply an input, it will output a dummy compression set of data.

Other are options set by default:

- compilation_level: 
   WHITESPACE_ONLY
   SIMPLE_OPTIMIZATIONS (default)
   ADVANCED_OPTIMIZATIONS
   
- output_info:
    compiled_code (default)
    warnings
    errors
    statistics
    
- output_format:
    text (default)
    json
    xml

Return the compressed version of the javascript code as a scalar by default.
