@lee great news, thanks for letting us all know about clj-kondo being added as an option to the Clojure layer in Spacemacs

To enable it, pull down the latest develop branch and add this to your .spacemacs configuration in dotspacemacs/layers

(clojure :variables
              clojure-enable-linters 'clj-kondo)

Of course you need to install the clj-kondo binary to a path that Spacemacs is aware of https://github.com/borkdude/clj-kondo/blob/master/doc/install.md

I just created a pull request to update the Clojure layer documentation for linters. Comments on GitHub most welcome. https://github.com/syl20bnr/spacemacs/pull/12685

Updated, did the config changes, works great. Now for me flycheck modd is also active now in clojure mode… 👍
