Add ClosureCompiler filter.

[jadb]

A new filter for those of us who want to use the Google Closure compiler API. Similar to the ClosureJS filter but without having to install JAVA nor the closure/compiler.jar.

The compilation level can be set using the level key in settings like so:

[filter_ClosureCompiler]
level = SIMPLE_OPTIMIZATIONS

One can also check statistics and/or warnings (only in debug mode):

[filter_ClosureCompiler]
statistics = true
warnings = true

Furthermore, extra parameters can be passed to the API like so:

[filter_ClosureCompiler]
level = ADVANCED_OPTIMIZATIONS
formatting = pretty_print
externs_url = http://www.myserver.com/myexterns.js

That's about it!

Hoping it is judged useful to others and gets added to the plugin's core.

Best,

Jad

Does this need to be configurable?

[jadb]

No.

Bumping this to see if there are any chances this will get merged soon so I can use the original repo again?

Why is this printing here?

[jadb]

For the shell command's output. Should I remove it?

[markstory]

I'm not overly familiar with the closure webservice, what purpose does printing this out serve?

[jadb]

Closure can return an output:

output_info
The value of this parameter indicates the kind of information that you want from the compiler.
There are four possible kinds of output: compiled_code, warnings, errors, and statistics. This
example uses the value compiled_code, which tells the Closure Compiler service to output the
compressed version of the JavaScript it receives in the request.

In here it's used to output 'warnings' and/or 'statistics'.
