This is a Ruby port of the outstanding UglifyJS project by Mihai Bazon. See that project on Github for full details.
The Ruby version of Uglify has several distinct advantages over the native JavaScript (Node) implementation:
- It is written in Ruby, which is great if you like that kind of thing.
- It is around 100x slower, leaving you time to make a cup of tea, coffee, or even go out to lunch.
- It is less well tested, giving you the chance to find and fix bugs yourself.
- It is not kept up to date, meaning there won’t be any scary feature enhancements on the way.
The Ruby port has some testing scripts, which simply compare the output from minifying a few scripts with the node equivalent.
