Hi.

I've just released a command-line tool for Rubyists.

jr: command-line JSON processor for Rubyists
https://github.com/yuya-takeyama/jr?ruby-talk
(Animated GIF and Tutorials are available here!)

Like jq you can filter/map/reduce JSONs in Ruby.
jr is written in Ruby with less than 30 lines of code.

Based on the UNIX Philosophy, jr can be combined with other UNIX tools
include jq.

Enjoy it.
