NOTE: rq
is in very low maintenance mode as my day job is taking up
a lot of my time. I will try my best to merge pull requests but will
not drive active development of this crate.
NOTE: rq
no longer ships with query support and a Javascript
engine is not included; instead, it focuses exclusively on format
transformation. You can still pipe into a runtime like node.js if
you need Javascript evaluation. Please see this issue
to discuss introducing a new query language.
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.
