Cider: Shadow CLJS Error

Created on 18 Sep 2019  路  11Comments  路  Source: clojure-emacs/cider

I setup a shadow-cljs project with deps.edn. After connect via cider-jack-in-cljs and working in the namespace, frequently a Cider error is thrown.

  This is an unexpected CIDER middleware error.
  Please submit a bug report via `M-x cider-report-bug`.

  If these stacktraces are occurring frequently, consider using the
  button(s) below to suppress these types of errors for the duration of
  your current CIDER session. The stacktrace buffer will still be
  generated, but it will "pop under" your current buffer instead of
  "popping over". The button toggles this behavior.

Unfortunately I was unable to reproduce but wanted to leave a heads up that a dep needs to be added to shadow-cljs-quickstart in order for it to build correctly.

The missing dep is: lilactown/hx {:mvn/version "0.5.3"}

I'm also seeing the same error for Shadow cljs repl when it tries to perform autocompletion. Unfortunately I can't remember at which point this broke but I believe it used to work on Cider 0.20.0.

@bbatsov many thanks for keeping us posted!
I can confirm that cljs completion with Shadow works again if I set cider-enhanced-cljs-completion-p to nil now.

My current setup apart from upgrading Cider hasn't been changed but here it is for our reference:

@louixs @Ninerian I was not able to reproduce any completion issues with suitable / shadow-cljs. Completion works well for me. Could you please share what code snippet (and cursor position) I can reproduce those issues with? Thanks!
