rq

NOTE: rq no longer ships with a Javascript engine included; instead, it focuses exclusively on format transformation. You can still pipe into a runtime like node.js if you need Javascript evaluation.

This is the home of the tool called rq (record query). It's a tool that's used for performing queries on streams of records in various formats.

The goal is to make ad-hoc exploration of data sets easy without having to use more heavy-weight tools like SQL/MapReduce/custom programs. rq fills a similar niche as tools like awk or sed, but works with structured (record) data instead of text.

It was created with love out of the best parts of Rust, and is distributed as a dependency-free binary on many operating systems and architectures.
