How to explicitly select clj-kondo as a backend for flycheck in lsp-mode? looks like lsp-mode brings own checker which reports nothing and this checker is set by default...

borkdude10:03:49

@U1EP3BZ3Q As I'm developing clj-kondo I always use my own clj-kondo version together with clojure-lsp. To do this, you have to disable diagnostics in ls-mode

borkdude10:03:17

lsp-diagnostics-provider :none

still it doesn't work...

ah wait... provider!

genmeblog10:03:11

@U04V15CAJ thanks a lot! I was setting wrong variable 😕 Now it works.

> brings own checker which reports nothing and this checker is set by default... FYI: lsp-mode checker uses server diagnostics, which if you are using clojure-lsp uses clj-kondo under the hood anyway with extrac checks like unused-public-var , so if you are not developing clj-kondo or similar and it's using lsp-mode already with clojure-lsp I suggest stick to lsp's diagnostics

genmeblog18:03:16

@UKFSJSM38 thanks, I know that clj-kondo is used under the hood. However it seems to skip some test (like unused fn args for example) which are important for me.

ericdallo18:03:18

not really, this is all delegated to clj-kondo, we have all features clj-kondo has

ericdallo18:03:35

maybe something with your config?

genmeblog18:03:16

Hmmm... Possibly. I posted Clojure part of confif at the beginning of this thread. Will take a look at this again...

genmeblog08:03:41

It was definitely something wrong with my config. Now it works. Thanks.

I started getting the weirdest error, and I'm not sure how to debug it. If I start a repl in a very barebone project, (one file with no definitions, and the deps.edn file is just {}, I get:

null
I wasn't having this problem yesterday, and I'm unsure about what changed

dpsutton16:03:23

i’m guessing something in your user file changed

dpsutton16:03:13

but just run `/run/current-system/sw/bin/clojure -J-Dghostwheel.enabled=true from a terminal and see if you can recreate. then try the whole form /run/current-system/sw/bin/clojure -J-Dghostwheel.enabled=true -Sdeps ‘{:deps {nrepl/nrepl {:mvn/version “0.9.0-beta3”} refactor-nrepl/refactor-nrepl {:mvn/version “3.0.0-alpha13"} cider/cider-nrepl {:mvn/version “0.27.2”}} :aliases {:cider/nrepl {:main-opts [“-m” “nrepl.cmdline” “--middleware” “[refactor-nrepl.middleware/wrap-refactor,cider.nrepl/cider-middleware]“]}}}’ -M:cider/nrepl`

Carlo16:03:02

where's the user file? The first invocation gives me a repl, the second one: 

$ /run/current-system/sw/bin/clojure -J-Dghostwheel.enabled=true -Sdeps '{:deps {nrepl/nrepl {:mvn/version "0.9.0-beta3"} refactor-nrepl/refactor-nrepl {:mvn/version "3.0.0-alpha13"} cider/cider-nrepl {:mvn/version "0.27.2"}} :aliases {:cider/nrepl {:main-opts ["-m" "nrepl.cmdline" "--middleware" "[refactor-nrepl.middleware/wrap-refactor,cider.nrepl/cider-middleware]"]}}}' -M:cider/nrepl
nREPL server started on port 45425 on host localhost -
and then no more output

dpsutton16:03:57

the file user.clj

dpsutton16:03:04

somewhere on your classpath possibly

dpsutton16:03:14

ok so it starts up successfully from the terminal

dpsutton16:03:51

another thing to try is to m-x nrepl-toggle-message-logging and see what messages are being sent and see if you can identify which form is causing an error

Carlo17:03:24

And if I do that in the *nrepl-messages file I get:

Carlo17:03:33

I think this could be the culprit: 

stacktrace ((dict "class" "clojure.core$with_meta__5437" "file" "core.clj" "file-url" "jar:file:/home/carlo/.m2/repository/org/clojure/clojure/1.10.3/clojure-1.10.3.jar!/clojure/core.clj" "flags" ("clj") "fn" "with-meta" "line" 220 "method" "invokeStatic" "name" "clojure.core$with_meta__5437/invokeStatic" "ns" "clojure.core" "type" "clj" "var" "clojure.core/with-meta") ...)

dpsutton17:03:34

i think it was blowing up on `(let [value (clojure.core/apply clojure.core/require cloju...” `

🙌 1
😍 1
Carlo17:03:01

where is that? (I know that I have written some code that looks like that in my emacs config

Carlo17:03:11

but where do you see it in the trace?

dpsutton17:03:42

message 4. and then an error

Carlo17:03:59

ok I understand what's the problem here; in my emacs config, I wrote: 

(after! cider-mode
  (defun cider-tap (&rest r)
    (cons (concat "(let [__value "
                  (caar r)
                  "] (tap> (with-meta __value {:portal.viewer/default :portal.viewer/pprint}))
                     __value)")
          (cdar r)))

  (advice-add 'cider-nrepl-request:eval
              :filter-args #'cider-tap))
it turns out that I can't do the with-meta wrapping, but I wish I understood why

Carlo17:03:46

basically I was trying to wrap every message that passes through tap> with some metadata (to set the portal viewer), but maybe some values can't accept metadata and they blow up?

dpsutton17:03:41

caar isn’t a valid function name

dpsutton17:03:48

and cdar what are those?

dpsutton17:03:24

ah i missed how they were interspersed in the string there

dpsutton17:03:48

well, that’s your problem. i’m not sure what you’re trying to accomplish but the error is in your code

🙌 1
Carlo17:03:36

sure, thank you, I think my original problem is solved, I'll confirm as I finish upgrading emacs. I'll ask if there's some construct that can't get metadata in another channel! ☺️

dpsutton17:03:34

anything that doesn’t implement IObj i believe

dpsutton17:03:42

so lots of java things. numbers, strings, etc

dpsutton17:03:49

its not universally applicable

dpsutton17:03:23

i’d probably turn that into something like (doto value portal/view) or something like that
