I wonder what could be going on with the ClojureScript Quickstart REPL...

Hi! Let’s the convo in one thread here. I’m not really familiar with the deps + shadow setup, but I think there has been some confusion around this and there is come improvement that could be added to Calva / the docs regarding this. You might find some helpful info here: https://github.com/BetterThanTomorrow/calva/issues/1591 and @U0ETXRFEW may be able to help more when he’s around.

From that issue: > I think it is due to that shadow-cljs dependencies are assumed to be present. You may be missing a necessary dependency (shadow.cljs.devtools ?), but I couldn’t say at the moment what exactly you need to do.

Thanks for posting the deps.edn and shadow-cljs.edn, @UGBKV7HHP. Calva tricks you a bit here. Since you are starting the project using npx shadow-cljs you should connect to it using the shadow-cljs project type. shadow-cljs.edn has :deps {:aliases [:dev]} which will make shadow take care of starting the project using clojure.

Your command line for starting the project is not ensuring Calva's dependencies are met, though. Consider using Calva to start the project (a.k.a. Jack-in) or use Calva's command Copy Jack-in command-line to clipboard to get a command line you can use that makes Calva happy.

Ok I was able to get that project to work using plain "shadow-cljs" rather than "deps.edn + shadow-cljs" thank you

I have another project I'm trying to get working that doesn't use shadow-cljs. I tried "Start and Project REPL and Connect (aka Jack-in)" > "deps.edn" > "alias :dev". I tried Ctrl+Alt+C+Enter on my user.clj. It doesn't seem to do anything. When I try to Alt+Enter a form, the REPL says

; Syntax error compiling at (src/dev/user.clj:38:3).
; Unable to resolve symbol: start in this context

Are you typing Ctrl+Alt+C+Enter or Ctrl+Alt+C Enter?

Put another way. If you run the command Load current file and dependencies from the command palette. Does something happen then?

When I choose that command from the command palette, I get the error:

Command 'Calva: Load Current File and Dependencies' resulted in an error (n.filter is not a function)

Hmmm, I've seen that recently somewhere....

No, that was something different: https://github.com/BetterThanTomorrow/calva/issues/1567

I think all the symbols in my file are defined. Here's the user.clj:

(ns user
  (:require
    [clojure.java.browse :refer [browse-url]]
    [com.walmartlabs.lacinia.pedestal2 :as lp]
    [io.pedestal.http :as http]
    [quiz.core :as quiz]))

(def schema (quiz/load-schema))

(defonce server nil)

(defn start-server
  [_]
  (let [server (-> schema
                   (lp/default-service {:graphiql true})
                   http/create-server
                   http/start)]
    server))

(defn stop-server
  [server]
  (http/stop server)
  nil)

(defn start
  []
  (alter-var-root #'server start-server)
  :started)

(defn stop
  []
  (alter-var-root #'server stop-server)
  :stopped)

(comment
  "Execution error (ExceptionInfo) at com.walmartlabs.lacinia.schema/verify-fields-and-args (schema.clj:1524)."
  "Field `Query/quiz' references unknown type `Quiz'."
  (start)
  (stop))

If something breaks before start is defined, then it won't get defined. Maybe (quiz/load-schema) results in an error?. Can you try it with clj on the command line and see what happens? Calva can sometimes hide some error messages (we should fix that):

I double checked and one of my dependenices was broken. Once I fixed it, that error message went away thanks

How do you send a form within a comment? I'm using Alt+Enter but I think that's sending the entire comment

It should work with Alt+Enter. Also the error you got when start wasn't defined, seems to indicate it worked then....

If you paste the comment form... maybe it is something special with it.

Ok when I Alt+Enter on (start) the REPL says:

; Syntax error compiling at (src/dev/user.clj:38:3).
; Unable to resolve symbol: start in this context

Do you still get errors loading the file?

When I load the file, the REPL says:

; Evaluating file: user.clj
; Execution error (ExceptionInfo) at com.walmartlabs.lacinia.schema/verify-fields-and-args (schema.clj:1524).
; Field `Query/quiz' references unknown type `Quiz'.
; Evaluation of file user.clj failed: class clojure.lang.Compiler$CompilerException

For some reason, it has part of the text of my comment in it

Actually when I try to change the text of that comment and load the file again, it still shows the same error. Not sure if it's not loading the changes to my file or if that's a genuine error message

Did you write that comment? Seems like documentation..

I wrote the comment

I wrote it in the user.clj file

But it's showing up in the REPL output

It's a little confusing sorry because it might be a real error and it might be reading out my comment

I think it is just the same error.

Ok if it's just a real error then I know what to do from there. Thanks

The messages in your comment there are just strings. You can alt enter on them and see them evaluate to themselves.

But when you load the file, the Clojure reader will not evaluate things in the comment form. It is a macro defined like so:

(defmacro comment
  "Ignores body, yields nil"
  {:added "1.0"}
  [& body])

Ok thanks for all your help

You're welcome!

Please consider posting a review https://marketplace.visualstudio.com/items?itemName=betterthantomorrow.calva&ssr=false#review-details ❤️

Yeah I'll def add a review once I've gotten a feel for it

Thanks for the report and the repro. I’ll have a look.

Thank you!

I sent a PR. 😃 Let me know if it works. It's a bit tricky for me to test it right now.

Awesome, It’s working! I’m expecting cider/cider-nrepl version should be in sync with version provided by copy jack-in command? Thank you very much!

> I’m expecting cider/cider-nrepl version should be in sync with version provided by copy jack-in command? Yes.

Hmmm, this might be related to https://github.com/BetterThanTomorrow/calva/issues/1611

I do get the list where I can select an alias, it is just that I do not want any of them :)

I can't reproduce your error either. I often don't want my aliases. 😃

The command you pasted looks a bit funny just before -M. There is a space before the ' instead of after it...

When I jack in it looks like

clojure -Sdeps '{:deps {nrepl/nrepl {:mvn/version,"0.9.0"},cider/cider-nrepl {:mvn/version,"0.27.4"}}}' -M -m nrepl.cmdline --middleware "[cider.nrepl/cider-middleware]"

If I run your command line though, it complaints

WARNING: Implicit use of clojure.main with options is deprecated, use -M

Sorry, tips... Run my command line and see if that works, then connect.

And please file an issue about the jack-in. Freaking strange!

version info of things would be great, including clojure and jdk

too

Yes, it could be possible that that’s behavior from an older version of clojure, but I’m not sure. -M does not require the use of aliases.

Could be old Clojure indeed. Will explore and get back! Thx!

You were right! I updated from clojure 1.10.1.619 to 1.10.3.1087 and now it works just fine

Wow that search seems very fast. I tried this out on a polylith work project with several deps.edn files.

Is there a command I need to run to switch between running repls? I opened two repls, and all evaluations get sent to the second one. I’m guessing I need to switch connections somehow?

@U08TWB99B Calva can only be connected to one project at a time, So ”switching repls” means disconnecting from one and connecting to another. But Calva does the disconnect automatically when you connect to another repl, so .... well, try this: Start two repls from projects in the same repo/workspace (outside of Calva, so not jack-in). Then use Calva to connect to one of them. Then connect to the other.

Ok, thanks for clarifying. I’ll give it a try to connect to external repls. But, in the meantime, it’s awesome that I can use Calva in a monorepo now! I’ve been opening individual sub-directories in VSCode until now.

To your observation about the speed of the search, @brandon.ringe. It is a glob over all the files in the workspace. On my machine (a Mac M1 Max) it takes about 50-100 ms in the rather huge Pitch monorepo. I'm curious about the performance on less stellar machines. Calva logs the time the glob takes, so anyone reading this is encouraged to report the times printed in the console.

To avoid searching through large sub directories for naught, the search excludes some known non-project directories, like .git, node_modules, etcetera. This exclusion is configurable via the setting, calva.projectRootsSearchExclude . Docs here: https://github.com/BetterThanTomorrow/calva/blob/dev/docs/site/connect.md#monorepos--multiple-clojure-projects-in-one-workspace

To see the impact the exclusion has, remove all entries in that setting and bring up the project root menu.

I love the new feature 🙂 !!!

See this thread: https://clojurians.slack.com/archives/CBE668G4R/p1647974038051949. Just trying to keep the convo in one place. 😄

ooo, I raised the original issue - I'll have a check next time it happens! My colleague had the same thing happen today so it could be something at a project level

well, the assert should result in a different error, that's all. I'd just like to confirm and see if the message is different

sure, I'm just interested (and grateful) to see any progress on this

it's a side-effect of working towards changing some typescript options (turning on strictNullChecks)

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

I don't know if it helps, but the same occurred when I tried to connect to a remote repl.
