This directory contains the extractor, CodeQL libraries, and queries that power Ruby support in CodeQL products that GitHub makes available to its customers worldwide.

It contains two major components:

1. static analysis libraries and queries written in CodeQL that can be used to analyze such a database to find coding mistakes or security vulnerabilities.
2. an extractor, written in Rust, that parses Ruby source code and converts it into a database that can be queried using CodeQL. See Developer information for information on building the extractor (you do not need to do this if you are only developing queries).
