Fork me on GitHub

@lvbarbosa Well, it’s certainly doable as evidenced by the tools that exist. I think today you have 3 options - clj-kondo, clojure-lsp and clj-refactor. I like kondo, as it doesn’t require any extra setup from me, but I’ve heard good things about clojure-lsp and clj-refactor. Unused vars are not hard to implement in CIDER itself, I just never had the time for this.


Might be a nice experiment. bozhidar: do you think it's possible without any additional elisp? I looked at squiggly-clojure and it provides an elisp package


We’ll also need a bit of Elisp for the UI, but that should be trivial. It’d be really great if we had something like squiggly-clojure for kondo, that’s using middleware instead of just evaluating code, so it would return data that’s optimized for the Elisp clients. That can expand the usefulness of kondo to more than linting - e.g. you can directly expose the data needing for find-usages, bake project integration, etc.

Gotcha... I am scheduling some time for myself in the future to study Clojure tooling internals. I might be able to contribute afterward


Couldn't we make clj-kondo in Emacs rely on projectile's notion of projects to perform linting? Or maybe make clj-kondo project.clj aware?
