Yes, using #lsp is one of the ways https://clojure-lsp.io/features/#find-all-references-of-a-function-var-keyword-or-namespace-alias

does it work across projects?

oh, I see your point now

only if it's a mono-repo

word

and you open the mono-repo as a project-root

@U7EFFJG73 vars in different projects aren't the same var according to the compilers... right? or do i misunderstand the question. I think the common way this is done is through a database? Or if you important a project into another (like a library), wouldn't it be "the same project".

According to the compilers? No, I suppose not. I am asking about importing one project into another. Can Emacs track the usage of one var, from a library, across downstream usages in other projects. This is something intellij can do (unless I’m mistaken).

It’s not something I would normally expect, especially since the group of consuming projects would be arbitrary.

Intellij finds it if you import the root project, just like clojure-lsp will find it as well

oh, nice!
