How can I make this work with netrepl client

[Inc0n]

I am written a game in janet, so I starts netrepl first then the draw loop.

(def s (netrepl/server "0.0.0.0" 9365 env))
(setup)
(draw-loop)

And connect using

janet -e "(import spork/netrepl) (netrepl/client)"

The problem is it will not function properly and comint to just echo entered text, it may be the prompt, but after changing comint prompt regex to "^[^ \n]\\[[0-9.]+:[0-9]+\\]:[0-9]+: ", the same problem persist.

A netrepl prompt looks like this:

[127.0.0.1:9365]:1: whatever expression
whatever expression

I am out of ideas, and would appreciate some advise on this.

I haven't looked into netrepl support for ajrepl but there were at least two attempts for using Emacs with spork/netrepl:

• https://github.com/yrns/janet-netrepl
• https://github.com/sogaiu/a-janet-spork-client

I haven't tested the former one, but I would guess it would be faster because it uses bindat, whereas the latter one was just trying to get things to work (not much attention paid to efficiency).

It looks like janet-netrepl uses set-process-filter-multibyte which may no longer be in Emacs 29.

From Emacs' Changelog.3:

2022-08-19 Stefan Kangas <...>

Resurrect obsoletion warning for two functions

These were supposed to have been deleted, but never were. Resurrect their obsoletion warning and let's delete them in Emacs 29 instead.

• lisp/subr.el (process-filter-multibyte-p) (set-process-filter-multibyte): Resurrect obsoletion warning.
• etc/NEWS: Don't announce their deletion.

I tried modifying janet-netrepl a bit, but didn't have much luck getting it to work.

bindat itself seems to do some kind of multibyte to unibyte conversion and I suppose it's possible this is not working so well with set-process-coding-system (which is commented out). I'm not really familiar with bindat though so the previous statement may be quite off.

May be the author of janet-netrepl would be more informed about the situation.

In some limited testing, the other option (a-janet-spork-client) seemed to still work and that uses set-process-coding-system without issues AFAICT.

Thank you this is very informative, I will give a-janet-spork-client a go first then.

a-janet-spork-client works like a charm :) 🤣 (cry of happy tears)
