Future of Ruby – AST Tooling

1. fast

   1 2 259 2.6 Ruby

   Find in AST - Search and refactor code directly in Abstract Syntax Tree as you do with grep for strings (by jonatas)

   

   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.

2. InfluxDB

   www.influxdata.com featured

3. rubocop-rails

   2 7 841 9.2 Ruby

   A RuboCop extension focused on enforcing Rails best practices and coding conventions.

   

   Let's take a glance at the action_filter cop real quick here, but just a quick part of it:

4. ruby-next

   3 7 768 6.7 Ruby

   Ruby Next makes modern Ruby code run in older versions and alternative implementations

   

   As it would happen, the folks behind Ruby Next have some ideas here, and have done a significant amount of work in enabling this very vision to become a reality.

5. unparser

   4 1 314 7.9 Ruby

   Turn Ruby AST into semantically equivalent Ruby source

   

   There are already some techniques capable of doing just this, by combining Parser with Unparser, but of course such things can only be done on Ruby files read in rather than in a REPL session which is where a lot more fun could happen.
