I gave the team a half-hour crash course in jq, some of the key features of its data and execution model, and how to do a handful of useful everyday things.
After, I had so many questions for myself that I spent over an hour learning more jq. I now have a greater understanding for how brilliant the language is, and I would do that crash course differently.
I think I owe @hpr an episode, if there isn't one.
I found many cheat sheets and liked none of them. A cheat sheet would be perfect to go in the show notes.
In Github Actions, jq comes pre-installed in the default worker. This can save you a lot of headache. Don't try to manipulate JSON with bash or Python, that's just clunky and error-prone when you can use jq instead.
I rewrote some of my own code from half a year ago. It's now shorter, more readable (if you know jq – hence the crash course), has zero quoting issues and provides better error messages.
