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.

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 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 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 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.
