And don't forget the option of just calling into pry at the line in question and typing ls and show-doc. Also ripgrep is incredibly useful for navigating new codebases.
Yes, grep + debugger / pry were how I solved this when I was still writing lots of Ruby. I find it much more productive to be able to get these answers statically, but I was too strong when I said "impossible"; there's always some way to find the right code, or the VM wouldn't be able to run it :)
Yes, you’re quite right! Thank you again, I must remember to use pry more.
With ruby 3.1 I think we’re getting a new default debug.rb gem.
It will be interesting to see if pry or the beat ideas from pry can be integrated with that.
Solargraph is an amazing project but ctags is still just so fast and low overhead that it's what I mostly use.
ctag support is available for most editors and is built into Vim. You need to first generate a tag file (or have an editor plugin do it for you[3]) and then press Ctrl-] to go to definition.
