I’m setting up emacs to work with figwheel. I use ring to serve a clojurescript application and I want to be able to eval both clojure and clojurescript code.

do I need to launch two cider instances and connect each buffer to the right cider?

I’m a bit lost with all this 😅

I would guess so. I personally don’t use cider + figwheel. But I imagine you need two cider instances because you basically have two repls running (clojure & clojurescript).

I see

are you aware if there is a way of telling cider which repl use based on the file extension?

I guess I can live with figwheel outside of emacs anyway but it would be great

there is a wiki in the figwheel repo about how to do that

here https://github.com/bhauman/lein-figwheel/wiki/Using-the-Figwheel-REPL-within-NRepl

oh, thanks a lot!

@rcoedo cider will do that automatically

The file extension thing

As for how to start the figwheel repl

I think there are several ways

If you use the project.clj described here https://github.com/bhauman/lein-figwheel/wiki/Using-the-Figwheel-REPL-within-NRepl#setting-up-cider

@malabarba: then I’m probably missing something 😞

I run cider-jack-in-clojurescript, which launches a nrepl server and two cider buffers: one for clojure and another one with figwheel

but I need to tell emacs to use the cljs cider process with cider-assoc-buffer-with-connection

otherwise I cant eval clojurescript in that buffer

Hm... That shouldn't be necessary

Do you think you can share a minimal project for us to reproduce that?

Also, do you get any warnings on the repl buffers?

no warnings

this is the project

also, I have this in my init.el

@rcoedo: I assume cider is in your profiles.clj?
