Not sure if I'm in the right channel, but I'm experimenting with clojurescript after a fairly long hiatus and I'm running into an issue with doc: I do not get any output except for a line of dashes, no matter which var I try:

clojure -Sdeps '{:deps {org.clojure/clojurescript {:mvn/version "1.12.145"}}}' -M -m cljs.main
ClojureScript 1.12.145
cljs.user=> (+ 1 2)
3
cljs.user=> (println "printing works")
printing
nil
cljs.user=> (doc println)
-------------------------nil

This is with clojurescript 1.12.145, with firefox and chromium on Ubuntu. Maybe I'm doing something wrong.

Huh I just noticed that the println call only prints "printing" instead of "printing works"

Just tried, same thing here. The last version that works properly that can be accessed via Maven Central is 1.12.42. 1.12.110 and 1.12.112 are unavailable, and the next 1.12.116 shows that behavior.

joost-diepenmaat 2026-10-15T11:32:14.869859Z

@p-himik yes 1.12.42 works for me too. ~~What's also interesting is that history navigation (cursor up) also works in 1.12.42, but does not work for me in 1.12.145~~

p-himik 2026-10-15T11:32:39.720179Z

That navigation comes from clj, not from CLJS. In your OP you used clojure - it doesn't provide history.

joost-diepenmaat 2026-10-15T11:33:23.115519Z

ah yes. you're right. I switched to clj to see if it made any difference in printing.

Alex Miller (Clojure team) 2026-10-15T11:45:17.981889Z

clj is just clojure + rlwrap

Alex Miller (Clojure team) 2026-10-15T11:46:16.785539Z

Maybe something with output stream flushing?

joost-diepenmaat 2026-10-15T11:48:06.810519Z

dunno. (flush) doesn't seem to help in any case

clj -Sdeps '{:deps {org.clojure/clojurescript {:mvn/version "1.12.145"}}}' -M -m cljs.main
ClojureScript 1.12.145
cljs.user=> (println "printing works")
printing
nil
cljs.user=> (flush)
nil
cljs.user=>

joost-diepenmaat 2026-10-15T11:48:59.161229Z

note the missing "works" in the output

dnolen 2026-10-15T13:57:13.006659Z

I cannot reproduce this with master

p-himik 2026-10-15T14:01:35.521809Z

Ah yeah, can confirm.

dnolen 2026-10-15T14:53:55.723889Z

there was a fairly problematic browser REPL specific issue that was resolved after the last 1.12 release. It had been hanging around for some time
