For example, I can evaluate (ex-info "Oh no" {}) and the repl windows pretty prints it just fine, and the evaluation result is printed next to the form

But if I evaluate (throw (ex-info "Oh no" {})) absolutely nothing happens.

It is still evaluated, it’s just that the exception goes … somewhere

(try (throw (ex-info "Oh no" {})) (catch Throwable e (println e))) evaluates to nil and repl shows the exception

@U0GE2JPNC you might want to open developer console in VSCode (`Help/Toggle Developer Tools` ). Maybe you'll find some exception in there.

What kind of project is this? How do you start it?

I start the clojure process with nREPL first, then Connect to Running REPL…

But this happens also when I tried with babashka and Start a REPL project and Jack-in

Hmmm…. tried with fresh project and Start REPL and exceptions are shown normally

So there must be something in my projects that causes this. What could it be?

@U01LFP3LA6P I get this kind of messages, but they seem to come all the time, not when eval causes an exception

are you using anything debugging-related in calva?

There are no interesting message at the terminal where you started the REPL?

No, I don’t thinks so:

This is the Calva evaluation results output window.
; TIPS: The keyboard shortcut `ctrl+alt+c o` shows and focuses this window
;   when connected to a REPL session.
; Please see  for more info.

;   - You can edit the contents here. Use it as a REPL if you like.
;   - `alt+enter` evaluates the current top level form.
;   - `ctrl+enter` evaluates the current form.
;   - `alt+up` and `alt+down` traverse up and down the REPL command history

Oh, I meant the shell where you started the repl.

@U0GE2JPNC It looks like the repl you’re connected to does not include cider-nrepl middeware (judging by that debugger message in the dev console). I’m not sure if that’s causing your issue with exceptions though, but it’s worth looking into.

I think I had this happen to me a few days ago. IIRC, I fixed it for myself by starting the repl through the jack-in command (rather than connecting to it and starting in a separate terminal shell).

@U9A1RLFNV Ok, that narrows it down, thank you. It has worked for me, but I guess I have changed classpath so that cider-nrepl is now missing. I’ll look into this.

@U021JR5PY3B That would be the best way, I’m sure. Unfortunately that’s not an easy to achieve for me, I have a setup where everything, including my service with nrepl, is started by docker-compose.

You can copy the command for jack-in by using the Calva command (search the command palette for “copy jack-in”) and paste it somewhere to see what Calva injects. You can either start your project repl in a similar way (with docker-compose, I guess), or you can modify your project file / configuration to include the dependencies.

Thankyou!!!

I did that “copy jack-in to clipboard” thing (which by the way is just amazing think), but I now remember that at some point I read from nREPL docs that the --middleware argument is not required anymore

…and I remved it

everything seemed to work just fine, until much later I noticed this exception thing

I added the "--middleware" "[cider.nrepl/cider-middleware]" back to my deps.edn and now it works again

🙇

I’m not sure if there’s a way, but Calva does not provide a way that I know of. Maybe there could be something with lein/clj that helps with this, but I don’t know that you would be able to easily read the results or navigate to the files.

the definition probably gets opened via clojure-lsp, right? So generic "open namespace by name" or "list namespaces" features would probably need to be implemented in there first.. (?)

When a repl is connected, definitions are opened via Calva (maybe with nrepl/cider-nrepl help). When the repl is not connected, definitions are opened via clojure-lsp.

There’s a feature request here for being able to navigate to namespaces by name: https://github.com/BetterThanTomorrow/calva/issues/545. It’s somewhat related, but not really what you originally requested.

actually that seems like a very nice feature to have and is pretty much what I originally had in mind. Something like "open namespace/symbol" with modal window offering fuzzy search functionality and then opening the source the same way as F12 does.
