Toward Idris2 support on Vim, could use advice and help

[cheery]

Hi. I started working on Vim8/Idris2 modification that interacts through --ide-mode. I've gotten things working badly, but there are few odd things about the function of the IDE mode that I don't figure out.

What am I supposed to do when I reload a file through idris-mode? Sometimes it's giving me 'return' response and other times it's not doing that. The IDE protocol documentation doesn't tell me what kind of choreography should the editor carry out.

The another question is with the "make-case". It's giving me a nice "fill-this-in" structure. How do I properly do the replacement though?

Also interested what do you think of the code. It's asyncronously running and I tie it up together with guard functions that retry on a task when progress is made.
