I’m not talking about a julia mode for vim - that exists and is lovely. I’m talking about the command line in the REPL - so that when you can escape partway into a long command you can use vim-flavored actions to change your REPL input. It is massively powerful if you have vim in your veins.
I understand from this ancient issue that Julia gave up GNU Readline long ago, and it was left to an “intrepid” developer to build. I’ve looked a bit at julia/stdlib/REPL to find the hooks and approach to do this, but have to ask:
Is someone already doing this? What is involved in doing this? What will make it challenging? It’s an itch I’d like to scratch, but I’ve got work to do (we all do) as well.
