hi all i'm trying to use shadow's cljs repl with cider

I cider-connect to shadow's nrepl port, then (require '[shadow.cljs.devtools.api :refer [repl]]) and (repl :my-build)

however I can't type directly into the new cljs repl (brought by the (repl ...) above)

instead emacs shows up a Stdin: input dialog

and whatever i typed in that stdin dialog will be evaluated in the browser

shawdow's wiki says something about this at https://github.com/thheller/shadow-cljs/wiki/REPL

Quoted from the above: This DOES NOT WORK while in nREPL unless your nREPL client supports needs-input

but I don't understand what that means

btw, the cljs-repl works nornmally if I just start it from a clj-repl outside of emacs, eg with boot repl -c

@myguidingstar I tried and could not make it work either. One thing that differs that comes to mind is the prompt: you need another regex

I've just got an answer from shadow-cljs

i should use (shadow/nrepl-select ...) instead of (shadow/repl ...)

Lol I was going to add...btw the wiki has that: https://github.com/thheller/shadow-cljs/wiki/REPL

I was working on a shadow-mode a bit a couple of weeks ago, but it was more of an inferior mode than a fully fledged cider experience

needs-input is used when something tries to read from *in* and can't get anything. The client should prompt the user for input at that time.

it can also happen in another way. (read nil) will prompt the user for input, so if there is a read call on a nil variable you will see this as well. My first look would be to find all reads and see if any of the forms could be nil

I'm presuming this isn't a mistake, and is actually intentional & correct usage of the nREPL given that it's part of the docs.
