[fmnoise]

I'm getting an error when trying to eval defn with #light tag

Caused by java.lang.RuntimeException
   Unable to resolve symbol: STATE__ in this context

@Malabarba @vspinu Any thoughts on this?

@fmnoise Does this happen in the absence of refactor-nrepl, btw? I'm trying to rule out some weird interaction between it and cider-nrepl.

[fmnoise]

yep, same error with absence of refactor-nrepl

[vspinu]

I am attempting to replicate this but getting instead

1. Caused by java.lang.IllegalStateException

   #'cider.nrepl.middleware.enlighten/light-reader

[fmnoise]

@vspinu I also seen it once

[fmnoise]

hm, haven't notice that before but STATE__ error starts appearing when you turned on enlighten mode once, before that it's

Attempting to call unbound fn:
   #'cider.nrepl.middleware.enlighten/light-reader

[fmnoise]

so steps

1. use #light
2. eval defn with #light, Attempting to call unbound fn: #'cider.nrepl.middleware.enlighten/light-reader should appear
3. turn on enlighten mode
4. eval defn with #light, Unable to resolve symbol: STATE__ in this context should appear Turning off enlighten mode doesn't change behavior, so STATE__ error appears each time when you eval defn with #light

[vspinu]

I see it. Thanks. Will have a look.

So -- I'm still seeing the exact behaviour outlined in https://github.com/clojure-emacs/cider/issues/2632#issuecomment-491596822 in my pretty up-to-date environment:

GNU Emacs 27.1 (build 1, x86_64-pc-linux-gnu, X toolkit, Xaw scroll bars) of 2020-11-18 CIDER 1.0.0snapshot (package: 20201113.1222)

Anywhere that I could go to help out with this?
