scittle 2026-10-05
Hey, I'm noticing that scittle doesn't seem to have the js-debugger primitive: https://cljs.github.io/api/cljs.core/js-debugger
Here is an example app:
(ns debugger)
(js/console.log "Hello")
(js-debugger)
(js/console.log "World!")

you can call (js/eval "debugger;") but I doubt that this will be useful in scittle, since the code runs in an interpreter and you'll mostly see interpreted frames

if you want this to be more useful, look at #C03U8L2NXNC which is a compiler
Okay, I had a hunch that might be the reason you didn't add it.
> if you want this to be more useful, look at #C03U8L2NXNC which is a compiler Thanks I'll give that a look too.
@borkdude I take it VMXXX are interpreted frames?

I think that's the JavaScript VM. Screenshot?
OOOH, actually you're right. It was just a single file with the line debugger;. Which probably came from the js/eval call. 🙂
Okay, I have another question (sorry about exploding the traffic on this channel, if there's somewhere else I should be asking things please redirect me 😉 ). Anyway, I'm just playing around with scittle and have the following program:
(ns debugger)
(def x {})
(defn foo [a]
(fn []
(.doesnotexist a)))
(js/console.log "Hello World")
(let [y (foo x)]
(js/console.log (y)))debugger - debugger.cljs:10:19
debugger - debugger.cljs:10:3
debugger - debugger.cljs:9:1(.doesnotexist a) is on line 6. Am I doing something wrong here?borkdude 2026-10-05T16:35:00.501629Z
Thanks, the interpreter didn't record the location of the instance method call, I'll fix that when you can make an issue about it. This is a workaround where you do see the right location:
(ns debugger)
(def x {})
(defn foo [a]
(fn []
(identity (.doesnotexist a))))
(js/console.log "Hello World")
(let [y (foo x)]
(js/console.log (y)))❤️ 3

Absolute hard agree!

Well, I'm not unpaid, some people who are using my stuff hard enough are sponsoring me and they allow me to do this basically :)
