Ruby LessJs

Ruby LessJs is a bridge to the official Javascript-based Less.js compiler.



gem install less-js


This library depends on the less-js-source gem which will be updated any time a new version of Less.js is released. (The less-js-source gem's version number is synced with each official Less.js release.) This way you can build against different versions of Less.js by requiring the correct version of the less-js-source gem.

Note: version 1.1.1 of Less.js is tagged as on the less-js-source gem.


The ExecJS library is used to automatically choose the best JavaScript engine for your platform. Check out its README for a complete list of supported engines.

Lifted From

The template for this gem was lifted from Joshua Peek's ruby-coffee-script gem.
