Starting a cider REPL freezes emacs after emidje installation about emidje HOT 3 CLOSED

@aguerra which version of Cider are you using and how are you starting the REPL (via cider-jack-in or cider-connect)?

from emidje.

I've reproduced the issue after upgrading to Cider 0.20.0. In fact, I hadn't had time to bump cider-nrepl on midje-nrepl (there were some breaking changes specially in the compatibility with org.clojure/tools.nrepl), but the problem that you reported is related to this version.
I've started working on the fix. For now, you can disable the nREPL injection by setting emidje-inject-nrepl-middleware-at-jack-in to nil:

(use-package emidje
  :ensure t
  :init
  (setq emidje-inject-nrepl-middleware-at-jack-in nil)
  :config
  (eval-after-load 'cider
    #'emidje-setup))

Alternatively, you can disable the middleware entirely for now:

(use-package emidje
  :ensure t)

Thanks for catching this one.

@aguerra I've published a new snapshot version of midje-nrepl with the fix. If you start the REPL via cider-jack-in everything should work normally. Thank you again for opening the issue.
