Hi. Is there a way for the test results to output the complete path of a failing test file? For example, suppose I have the following structure src + main ++ module1 +++ file.cljs + test ++ module1 +++ file_test.cljs when I have a failure, I get

FAIL in (my-test) (module1/file_test.cljs:31:13)

not built-in no

Hello again folks! Hope you're having a great day wherever you are. 🙂 I've pushed things as far as I can without a working cljs REPL so have carved out sometime to get a Emacs/Cider-based nREPL connection working with shadow-cljs. The blocker right now is Cider trying to require cider.piggieback, which I've read shadow-cljs doesn't use at all. I'm using cider-jack-in-cljs with both :deps and :nrepl in my shadow-cljs.edn:

{:deps  {:aliases [:client]}
 :nrepl {:port 8777}
 ,,,}

/usr/bin/clojure -A:dev:test -Sdeps '{:deps {me.raynes/fs {:mvn/version "1.4.6"} compliment {:mvn/version "0.3.6"} com.cemerick/pomegranate {:mvn/version "0.4.0"} org.tcrawley/dynapath {:mvn/version "0.2.5"} nrepl {:mvn/version "0.8.0"} cider/piggieback {:mvn/version "0.5.1"} refactor-nrepl {:mvn/version "2.5.0"} cider/cider-nrepl {:mvn/version "0.25.3"}}}' -m nrepl.cmdline --middleware '["refactor-nrepl.middleware/wrap-refactor", "cider.nrepl/cider-middleware", "cider.piggieback/wrap-cljs-repl"]'

My .dir-locals.el contains this:

((nil
  (cider-clojure-cli-global-options . "-A:dev:test")
  (cider-default-cljs-repl . shadow-select)
  (cider-known-endpoints . (("localhost" "8777")))

All I can point you to is https://shadow-cljs.github.io/docs/UsersGuide.html#cider

I wish Clojure would write to stdout/stderr so I could redirect output myself. 🙂

I don't use emacs/cider so I don't have a clue how it works

might be simpler to just connect to the REPL instead of jacking in

ie. just run shadow-cljs server or so and then connect remotely to 8777 (however you do that I don't know though)

the clojure call above doesn't seem to be using shadow-cljs

Thanks for the pointers, @thheller. I tried connecting to the nREPL server running inside my shadow-cljs watch process but I get errors about middleware being missing. I've added the middleware to my deps.edn and get the same errors.

seems fine? just adjust the versions in deps.edn?

Uno momento. I'll get the error from that. 🙂

I've added these deps to my :client alias:

cider/cider-nrepl             {:mvn/version "0.25.4"}
    refactor-nrepl/refactor-nrepl {:mvn/version "2.5.0"}

WARNING: CIDER 0.26.1 requires cider-nrepl 0.25.3, but you're currently using cider-nrepl 0.23.0-SNAPSHOT. The version mismatch might break some functionality! (More information)

I've checked my ~/.config/clojure/deps.edn and made sure there's no ~/.clojure/deps.edn. Where this snapshot version of Cider is coming from, I'm unsure.

And why the explicit artefacts in my deps.edn are ignored…

:aliases
 :client
  :extra-deps
   applied-science/js-interop    {:mvn/version "0.2.7"}
    cider/cider-nrepl             {:mvn/version "0.25.4"}

might be a better question for #cider

Slack ditched a curly brace there. It's definitely in my deps.edn file. 😄

Hmm. Cider doesn't manage my dependencies when I connect a REPL but I guess they might have some vendored snapshot or some dependency resolution thing they're doing somewhere.

I would expect it to respect deps.edn but I don't have a clue

either way it is saying it requires 0.25.3 and you have 0.25.4 so that might be the problem too

maybe try clojure -A:client -Stree or whatever the command was to list the tree. maybe that explains wheres its coming from

I've asked the question over here too: https://clojurians.slack.com/archives/C0617A8PQ/p1602595230188700 Hopefully some of the lovely people over there are using my dream combo of Cider and shadow-cljs! 🙂

@jcf I just noticed from the command above it had /usr/bin/clojure -A:dev:test

so that doesn't use the :client alias you setup?

That's correct. In my shadow-cljs.edn file I have :deps {:aliases [:client]} … Do I need the initial invocation of Clojure to include :client too?

That might get a little tricky as I don't always want to load up all my browser-based deps when I jack in. Maybe I can add those options to just the cljs opts.

I cannot answer cider/emacs questions sorry. From the command above it did not invoke shadow-cljs at all so whatever is in shadow-cljs.edn also has no effect.

Progress! 💥

I've added :client to my CLI opts.

ok now you are missing the shadow-cljs nrepl middleware

https://shadow-cljs.github.io/docs/UsersGuide.html#_embedded_nrepl_server

dunno how you add that

There's a cider-jack-in-cljs-nrepl-middlewares var that takes a list of strings from the looks of it.

cider-jack-in-cljs-nrepl-middlewares is a variable defined in
cider.el.

Value
("cider.piggieback/wrap-cljs-repl")

Set

Documentation
List of Clojure variable names.

I'm not sure if I need wrap-cljs-repl with shadow-cljs, right? I thought I read that shadow provides its own middleware.

you can keep it but you don't need it yes

Cool. Jacking in now. 🤞

I think this exception is shadow-cljs letting me know that I'm not building anything?

Execution error (ExceptionInfo) at shadow.cljs.devtools.server.runtime/get-instance! (runtime.clj:11).
missing instance

Not sure why an exception is thrown as that doesn't seem like an exceptional circumstance but maybe it's the way Cider's firing up the REPL internally.

https://shadow-cljs.github.io/docs/UsersGuide.html#embedded

you are running in embedded mode so shadow-cljs isn't even started yet

you need to start it

it is an exception because the jack in likely wants to switch you to the shadow-cljs REPL which obviously can't work when shadow-cljs isn't even running

I recommend connecting remotely ... doing all of this yourself is a lot of effort for basically no gain

Okay, I'll stick with connecting Cider to shadow-cljs and forget about jacking in.

I'll be starting from here:

looks like you got it. just open the browser with your code loaded. (assuming this is a browser build of course)

That's awesome! I can connect to the browser and eval stuff like (js/alert "Hi, there!").

Completion blows up quite spectacularly. 😄

thats likely https://github.com/rksm/clj-suitable/issues/15

Yeah, I've stumbled across that issue today.

you can turn that off to just get regular completion

@thheller do you know how I turn that off to get regular completion?

I can eval code but completion and eldoc are broken.

Eldoc gives you the function signature in the bottom of the editor window, which is super handy.
