You have to manually ":Connect" to the Figwheel nREPL (1, localhost, 7888, return) and then ":Piggieback" to establish the ClojureScript REPL. Everything should work as-is after that.

Note that if you create an .nrepl-port file first (with the contents "7888") then you only need to type the ":Piggieback" command -- the nREPL connection will be established automatically.

Stumbled upon this today. Can't thank you enough! This works great for me. 😄

Thank you for this!

Wow. Man, thank you so much!

This unfortunately did not work for me. Anybody mind sharing a sample project.clj just so I can debug whether my problems are being caused by other configuration stuff?

When trying to do cpr I get the following error:

Error detected while processing function <SNR>52_Require:
line   13:
E716: Key not present in Dictionary: user_ns()})
E116: Invalid arguments for function fireplace#session_eval

Any ideas? Thanks!

@cassiomarques Are you starting the repl using lein figwheel?

Is this still relevant?

@Gonzih I'm still having to use this hack because the method described here gets me an NPE. I'm thinking figwheel-sidecar.repl-api/cljs-repl is returning nil.

I have to confirm that this patch is still relevant.

To reproduce, I've started a new figwheel template

lein new figwheel hello-world -- --reagent

Opened the figwheel repl via either lein figwheel (or lein repl, followed by (fig-start)).

Then opened a clojure file in vim and called :Piggyback. Then sent a form to the repl with cpp.

In the unpatched version, this was the error:

org.mozilla.javascript.EvaluatorException: Java class "[Ljava.lang.StackTraceElement;"
has no public instance field or method named "cljs$lang$protocol_mask$partition0$". (rhino.clj#41)^@'}

In the patched version, the result of e.g. (println "hello") appears in the browser console, the result of a side-effect-free evaluation (e.g. (+ 1 2))appears right in vim. Excellent!

thanks. the patch works (took me a while to find it).

According to this issue tpope/vim-fireplace#222 there is no need for this patch any more.
