Hello everybody!
I’m happy to announce jsc, the Javascript Compiler.
With jsc you can compile your JavaScript code throught Google Closure
Compiler REST service[1].
== Install
Run:
[sudo] gem install jsc
or get source from GitHub - sub/jsc: Ruby API to Google Closure Compiler Web service
== Samples of usage
Get compiled code, if no errors are found:
jsc compiled_code.js
Just check for errors:
jsc errors.js -e
Run jsc --help for more info about allowed options.
== Flymake
For GNU Emacs users, jsc provides a flymake[2] compatible output. So you
can use
jsc+flymake to have a syntax check tool running in the background while
editing
javascript files:
