jsc, JavaScript Compiler by Davide Saurino http://github.com/sub/jsc

Ruby API to Google Closure Compiler Web service.

== Features

With jsc you can compile your JavaScript code throught {Google Closure Compiler REST service}[http://code.google.com/closure/compiler/].

The package comes with a jsc command which accepts several options, run:

jsc --help

for help.

More in details:

• Ruby API actually is a single function call, JSCompiler.compile()
• Handling of JSON responses, parse and print them (same output of the Google web interface!)
• Handling of Server Errors responses
• Compile a file or a piece of code
• Emacs snippet to compile code your code for errors and warnings
• flymake compatible

Check {Google API Reference}[http://code.google.com/intl/it-IT/closure/compiler/docs/api-ref.html] for more info about accepted parameters.

== Synopsis

Get compiled code, if no errors are found:

jsc js/compiled_code.js

Compile a file, check for errors:

jsc js/errors.js -e

Compile a file, check for warnings:

jsc js/warnings.js -w

Compile a file and get compression stats:

jsc js/compiled_code.js -s

Compile a piece of code, check for errors:

jsc -e -c "function("

Compile a file for both errors and warnings:

jsc js/compiled_code.js -a

== Install

If you have gemcutter in your gem sources, run:

[sudo] gem install jsc

== Emacs+flymake+jsc

For GNU Emacs users, jsc provides a {flymake}[http://www.emacswiki.org/emacs/FlyMake] compatible output. So you can use jsc+flymake to have a syntax check tool running in the background while editing your javascript files. Look at the {wiki page}[http://wiki.github.com/sub/jsc/flymake] for more info.

== Emacs snippet

Do you want to compile your code right from Emacs?

Copy

plugins/jsc.el

to your emacs load-path and restart Emacs.

Now, select the code to compile and run:

• CcJe to check for errors
• CcJw to check for warnings.
