ASTs in Ruby - Node Pattern and Introducing RuboCop
Oh, and that regex bit? Remember how we have Rubular for regex? We have the NodePattern Debugger for ASTs which you will find incredibly helpful, in fact you might open it now and try out some of these examples to make sure I'm not pulling a Fast one. (No, I'm not apologizing for that one.)

Future of Ruby – AST Tooling
Some of these tools have even already been wrapped, like Jonatas's work on FFast which works on top of NodePattern and some of RuboCop's previous work. Really the only things between us and this future is a bit more wrapping and polish, as well as integrations into something like VSCode.

Ancestry is a gem that allows the records of a Ruby on Rails ActiveRecord model to be organized as a tree structure (or hierarchy). It employs the materialized path pattern and exposes all the standard tree structure relations (ancestors, parent, root, children, siblings, descendants), allowing all of them to be fetched in a single SQL query. 3,136 stars by now
