Guile over nREPL, guile-ares-rs integration

[abcdw]

Hi @Olical!

On fediverse, you mentioned that stdio Guile REPL is far from perfect and that it would be cool to make a Guile nREPL integration for Conjure. A few weeks ago we released guile-ares-rs (RPC server based on nREPL protocol), it implements all the basic functionality (evaluation, interruption, completion) and seems to be a very reliable.

There is an emacs-arei client, which can be used as a source for inspiration.

I don't use vim for almost a decade already and thus it would be not very rational to write a client/integration on my own, however, I would be glad to share the knowledge and implement missing functionality on the server side to help someone to implement the client.

Cc people using guile and vim I know: @ekaitz-zarraga, @Millak

I know of vim-slime, which I've heard is like SLIME for emacs, but I've never used emacs or actually used vim-slime. https://github.com/jpalardy/vim-slime

This is really cool, thanks for sharing! This should work great when I can refactor the nREPL support into a reusable layer.

Nice! Don't hesitate to contact me if you have any questions, need support or changes on ares-rs side. Wish you great holidays! :)

Tried the basic parts of this today and the nREPL side works - would be great to have it in Conjure ;-)

This is what worked for me:

1. Install Guix as a package manager on top of any Linux distribution
   Install it and do a guix pull to get the latest package definitions: already had this.

2. Start a guix shell environment / install guile-ares-rs

$ guix shell 
$ guix package --install guile-next guile-ares-rs

$ guile -c '((@ (nrepl server) run-nrepl-server) #:port 7888)'

This starts a nrepl and I can connect to it with netcat

3. Start a Clj nrepl

  clj -Sdeps '{:deps {nrepl/nrepl {:mvn/version "0.5.3"}}}' -m nrepl.cmdline -c --host 127.0.0.1 --port 7888

We can send really basic stuff:

user=> (+ 1 1)
2

user=> (list 1 2 3 4)
(1 2 3 4)

user=> (reverse '(1 5 9))
(9 5 1)

<ctrl>c doesn't seem to actually work to interrupt it though.

Anything more complicated hits the fact that we're inside a Clojure environment.

I couldn't get Conjure to connect to it with ConjureConnect.
