I can't reproduce this :thinking_face: I've only ever seen this when something in the REPL itself has rebound the thing that allows you to use reader conditionals.

(I just ran a reader conditional in a .cljc)

How are you starting the REPL?

; eval (root-form): (defn testing [] #?(:cljs :this :clj :that))
#'dev.sandbox/testing

I use lein repl and connect to that

(as an aside, I was at v4.3.0 so I tried bumping to v4.6.0, but still the same error)

does it matter that my repl is "no-env"

; Assumed session: California Spangled ()

Hmm, that means Conjure tried to check if you're Clojure or ClojureScript in your current session through a reader-conditional and got an error or nil.

That session type works by reader conditionals, so it makes sense that it's broken if reader conditionals are playing up.

Could you try ,sQ to kill all of your sessions, just in case?

sure. here are the results:

; Closed all sessions (2)
; --------------------------------------------------------------------------------
; Assumed session: Scottish Fold ()
; --------------------------------------------------------------------------------
; Sessions (1):
; >1 - Scottish Fold ()
; --------------------------------------------------------------------------------
; eval (root-form): (defn testing [] #?(:cljs :this :clj :tha...
; (err) Error printing return value at clojure.lang.Util/runtimeException (Util.java:221).
; (err) Conditional read not allowed

Oh yeah, I made no env link to a wiki page explaining the situations that it can occur 😅

Can you use reader conditionals in the lein repl?

(sorry about remote debugging, there's not really anything in Conjure for this, so I'm just trying to help diagnose where the issue lies)

I appreciate you helping out!

I am able to evaluate that form

Fun times! So your REPL itself is configured... interestingly.

Could be your tools.repl or Clojure version being held back by some dep :thinking_face:

well, not quite. this does look like a repl issue because evaluating #?(:cljs :this :clj :that) returns nothing

so there's my problem -- no conjure!

thanks for your time!!

Yay but also 😭

No problem! I'm guessing it's a dependency causing it. I'd try lein repl in another project / fresh dir to see if that's okay

If it is and it only recently broke, it's probably down to a recent dep change

I'll let you know here when I find the culprit!

Okay, well this isn't minimal by any stretch, but I fixed it by removing the nrebl set up that I was listing in my lein/profiles.clj user profile:

{:nrebl {:resource-paths ["/Users/onno/opt/REBL-0.9.226/REBL-0.9.226.jar"]
         :dependencies [[rickmoynihan/nrebl.middleware "0.3.1"]
                        [org.clojure/core.async "0.4.500"]
                        [org.openjfx/javafx-fxml "11.0.1"]
                        [org.openjfx/javafx-controls "11.0.1"]
                        [org.openjfx/javafx-graphics "11.0.1"]
                        [org.openjfx/javafx-media "11.0.1"]
                        [org.openjfx/javafx-swing "11.0.1"]
                        [org.openjfx/javafx-base "11.0.1"]
                        [org.openjfx/javafx-web "11.0.1"]
                        [cljfmt "0.6.4"]]
         :repl-options {:nrepl-middleware [nrebl.middleware/wrap-nrebl]}
         :injections [(require 'nrebl.middleware)
                      (require '[cognitect.rebl :as rebl])]}

Good spot! There may even be an issue on that project about this, I presume it's holding a common dependency back to a point of breakage, or it's not providing a flag to the REPL as it starts up as it should.

yeah, my REBL setup is likely very outdated too (not to mention jury-rigged)

Thanks again for your time; and sorry to waste it when I hadn't tried things out at my repl first. My bad!

Not a problem! I like to triage and work out if it's something that I did and might be happening in lots of places without my knowledge quickly. Helping you out through rubber ducking is a huge bonus 🙂

So glad they made it!
