clj-kondo v2020.06.21 introduces a new hooks API which allows writing code to support custom macros https://github.com/borkdude/clj-kondo/releases/tag/v2020.06.21 This work was sponsored by Clojurists Together as part of their Summer of Bugs program. Thanks!

Gonna give this a spin, today

How do I debug a hook? Like, check the output?

@dominicm Try (prn (api/sexpr node))

Blogged about the new feature here: https://blog.michielborkent.nl/2020/06/21/clj-kondo-hooks/

The new hooks API looks interesting! One thing that wasn't clear to me from reading the documentation was whether clj-kondo treats the auxillary files in .clj-kondo as regular namespaces? Eg. If I write my library and put its macroexpand definitons in .clj-kondo/foo.clj, does that conflict with another library's definitions in the same foo ns? Wondering why this isn't namespaced the conventional way with the library name: https://github.com/borkdude/clj-kondo/blob/master/.clj-kondo/macroexpand/one_of.clj

@qythium clj-kondo doesn't execute any other files than those in .clj-kondo and since there can only be one .clj-kondo/foo.clj file at the same time, there isn't any conflict

and you can load that file using (require 'foo) or refer to it from the config as foo/foo (assuming it has a function foo). having said that, it's a good habit to use at least two segments in a namespace

Thanks for the new linting power @borkdude! I’ll see if I can get it working on rewrite-cljc’s internal import-vars-with-mods macro!

Also, where does one find the actual API for clj-kondo.hooks-api ? I couldn't find such a namespace defined in the clj-kondo repo, only usages of it.
