@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.
