Hi,

first of all thanks for this checker.

I just started a new project, using the Luminus template. After CIDER is up and running with C-c M-j, upon editing a .clj file I keep getting this error:

Could you show me the result of running the (do (require ... ) form straight from the REPL?

[pnf]

Well, that's (your first, pre-edited response) what we expect, so the problem has to be in the transmission of this boring result back to emacs. Out of curiosity, did you get a "things will break" warning when cider started? What I'm beginning to suspect is a conflict between the dependencies of the latest cider-nrepl snapshot and those of core.async.

No, no issue with CIDER. Neither in the *Messages* buffer, nor in the REPL.

[pnf]

Ok. I won't have access to a real computer for a few hours, but in the mean time, a few more questions.

1. Definitely no message when cider starts about a mismatched cider-nrepl version? I ask because others have reported this.
2. Are you setting the dependencies in a profile or via jack-in? Whichever it is, can you try the other one?

[anujsrc]

@pnf - I am also facing the same issue. If we add the squiggly dependency in ~/.lein/profiles.clj as mentioned in https://github.com/clojure-emacs/squiggly-clojure/issues/29 and https://github.com/clojure-emacs/squiggly-clojure/issues/39, the checker error goes way but I start getting the CIDER warning as mentioned here- https://github.com/clojure-emacs/cider/issues/1728 - It does say things may break as you pointed out.

[manuel-uberti]

@pnf

1. Yes, no message at all about the mismatched cider-nrepl version
2. I am setting the dependencies via jack-in. If I try the other way, I get the same behaviour as @anujsrc.

[pnf]

I have been completely unsuccessful determining how cider determines what version of cider-nrepl is being used. (@bbatsov can you give me some pointers?) In any case, we clearly are using the correct one, as confirmed both by the lein deps :tree output and looking at cider.nrepl.version/version directly from the REPL. @manuel-uberti, @anujsrc - Other than the CIDER warning, do you see anything - regular CIDER or squiggly functionality - actually breaking? My experience is that the wrong-number-of-arguments error from squiggly and the things may break warning from cider are orthogonal: i.e. squiggly breaks only when I didn't get the warning. One slight improvement I can make is to push the org.clojure/clojure dependency up to "1.8.0". When I do that, then (with a fresh lein new luminous project): (1) The behavior with injected dependencies fromcider-jack-in and with explicit dependencies in the :repl profile is identical; both result in the breakage warning, but no evident breakage. (2) A whole bunch of lein with-profile repl deps :tree inconsistency go away; I'm left with a few relating only to luminous, and an internal inconsistency within the core.typed dependency tree on tools.reader. By adding toos.reader to the exclusions for acyclic/squiggly-clojure, we can remove that last inconsistency warning, but it does not, as I'd hoped, somehow cause the "things may break" warning to go away. Later today, I'll push a squiggly "0.1.8" jar that depends on clojure "1.8.0" and modify the .el. to inject that dependency, along with the reader exclusion. There may be up to a day before the new elisp hits melpa, so there may be a period where you have to modify flycheck-clojure-dep-version manually.

[pnf]

Updated flycheck-clojure.el is on github ready for pick-up by melpa; the new jar, version "0.1.8" is up on clojars. Following @mrroman's discovery that the mismatched version warning only occurs with versions of core.typed 0.3.26 and later, I reverted the squiggly dependency to 0.3.25. I also brought this up on the core.typed google group, as the cider error can be reproduced without involving squiggly at all. At this point, I believe that the README, the sample project, the clojar and the .el are all in sync, and you should no longer see either things breaking or a warning that they will. (Well, things will break eventually, but hopefully not in the way we've been discussing.)

[pnf]

Per #45, the version mismatch error has something to do with AOT jars from core.typed, by explicitly depending on "0.3.32" :classifier "slim". So, yet another version tick today. Now to squiggly 0.1.9-SNAPSHOT. (So I can rashly push out further updates without having to change the version as often.)

[anujsrc]

Thanks @pnf - I will pull the SNAPSHOT tomorrow and give it a try.

[manuel-uberti]

Thanks for your effort @pnf, but I am still getting the same error message. I upgraded flycheck-clojure, jacked-in with C-c M-j and at every edit in a .clj file I get the message.

[pnf]

Are you using the latest .el, which injects 0.1.9-SNAPSHOT? If so, there's something in your environment that that I don't understand. I am testing on a new luminous project, with no profile set.

Yes, latest version with 0.1.9-SNAPSHOT. I'll try again on a new luminus project later and report back.

You see exactly this?

This doesn't mention squiggly at all. Are you sure you have the latest .el from github and have executed flycheck-clojure-setup?

Yes.

flycheck-clojure-dep-version is a variable defined in ‘flycheck-clojure.el’.
Its value is "0.1.9-SNAPSHOT"

And in *Messages*:

error in process filter: Wrong number of arguments: (4 . 4), 0 [2 times]
Error from syntax checker clojure-cider-eastwood: Done with no errors

[pnf]

That variable is defined when the .el is eval'd. It's the -setup function that adds it to the cider injection list. If you don't see the dependency in the lein parameters, then either -setup wasn't run, or you have some other problem. In either case, the squiggly jars won't be on your class path, so it would be surprising if anything worked.

This is weird, because if I completely disable flycheck-clojure I'm not getting the error. I'll check again my setup.

[pnf]

It sort of makes sense. If we're somehow evaluating flycheck-clojure functions without having the classes available, something terrible will happen.

This is my config:

  :ensure t

I'll try running flycheck-clojure-setup withouth waiting for Flycheck to be loaded and see if it makes any difference.

Nothing changed. My setup now:

(eval-after-load 'flycheck '(flycheck-clojure-setup))

The injection occurs at https://github.com/clojure-emacs/squiggly-clojure/blob/master/elisp/flycheck-clojure/flycheck-clojure.el#L196 You can examine cider-jack-in-dependencies directly.

[manuel-uberti]

I eval'd flycheck-clojure-setup via M-x, now I get the injection. This is what Flycheck is reporting in a .clj buffer:

core.typed:There was previously an unrecoverable internal error while loading core.typed. Please restart your process. (clojure-cider-typed)

[pnf]

Officially, you're on your own for issues with individual linters. However, I suspect you'll want to turn off core.typed here, unless you're actually using it in the project. You should probably test out a few bona-fide Eastwood and Kibit solecisms to make sure they're being highlighted.

[manuel-uberti]

Ok great. Let's consider this closed then.

Thank you for the patience and the support.

[pnf]

You're very welcome.

[manuel-uberti]

This fixed it.
