Currently cider-find-keyword doesn't work with clojure-ts-mode, because it relies on clojure-keyword-face text property (which is different for keywords for clojure-ts-mode). I've introduced a small helper which uses text property for clojure-mode and tree sitter based predicate for clojure-ts-mode.

Looks like it's not that simple. CIDER currently doesn't have clojure-ts-mode as a dependency.

[rrudakov]

Not sure how to fix the linter error. Any suggestions are welcome.

The treesit-* functions are only used if treesit feature is available, but I don't know how to tell linter about it.

[rrudakov]

I've figured it out :)

Let me think about this a bit, as I've got a small concern about leaking implementation details from the major modes in CIDER and I'm wondering what's the best way to abstract this away. Some work will definitely need to be done in this directly to fully embrace clojure-ts-mode. (unless it takes so much time to do it, that we'll merge the two modes first, as is scheduled for Emacs 32 :D )

[rrudakov]

Sure, sounds good to me. We could probably define some helper in cider-ts-mode (something like clojure-ts-keyword-at-point-p), but I wasn't sure that it's a good idea, it would be needed only to support CIDER.

[bbatsov]

That's what I was thinking as well, otherwise I would have done it by now. Perhaps we can wrap all direct calls to clojure-mode in some cider-foo-bar functions in the same file in CIDER, so we can all such glue code is contained within a single file. No better ideas come to mind right now.
