vi and Codex
Codex – as opposed to Copilot that lives within an IDE – plays nicely with command line tools. I like that because it ties the future of software development (some say the end) to its very beginnings. As a bonus, Codex sets up the nvim configuration in minutes. When I did this a year and a half ago, it took me days of watching YouTube videos and reading READMEs on GitHub.
