So, if I understand correctly you want to be able to echo some request params in the responses, right? I assume your client will processing those specially if they are present?

There’s nothing like this today, but I guess it’d be easy to add a middleware that just attaches certain request params to the responses.

@bozhidar Yes, exactly. Turns out it was pretty straightforward to build what I needed by just using op IDs to match requests and responses, and I can use that functionality for other things as well.

Is there an overview of bencode libraries for various languages that support streaming to build nREPL functionality?

I found one for python and for Rust. Obviously we have one for Clojure

I guess this page serves as such a resource: https://nrepl.org/nrepl/beyond_clojure.html

ah, btw @bozhidar - the nREPL server in babashka has now been broken out into a library: https://github.com/babashka/babashka.nrepl so the reference on that page could be changed to that

Python

I think clojure-vim maintains it now, but was written by Chas/Stu, I can't remember now.

@dominicm "it" being?

the bencode library

https://github.com/clojure-vim/nrepl-python-client

https://github.com/clojure-vim/nrepl-python-client/blob/master/nrepl/bencode.py bencode is inlined admittedly

it's nice how in almost any language the bencode impl ends up being around 200 lines

fireplace has a really short one

https://github.com/tpope/vim-fireplace/blob/6c968f26f0bd3dd04b18fad8761e0e9e1220a3da/pythonx/fireplace.py#L9-L77

so probably clojure-vim/nrepl-python-client should also be listed there?

yeah, it should

and the fireplace one

the page lists server implementations, but I think it's also useful to list client impls
