This seems to be the solution: http://blog.jenkster.com/2013/01/clojure-syntax-highlighting-in-emacs.html

Also you can configure clj kondo to analyze it like defn

you can add highlights to any symbol in clojure mode, i actually has an issue for clojure-mode related to this, though cider should really be doing this for you.

i'm using lsp for highlighting not cider , i'll try the clojure mode way now let you know

https://github.com/clojure-emacs/clojure-mode/issues/622

i haven't used lsp, i assume it's not cider, are you using cider-jack-in ?

i am, but i disabled cider highlights

anyway, the issue i posted was something cider wasn't fixing, so it seems ok to add special font-locking in clojure mode when other modes fail

does cider have a highlight face for macros or how would you use cider to highlight >defn

cider does do some fontlocking. you can see it when you open a clj file and it changes font locking after jack-in or file-load C-c C-l

highlight doesn't sound like font-locking, though... i'm not sure what that is.... i'm not an expert with cider, i fix stuff when i run into problems, but i generally don't want to know much about cider

interestingly any macro named with prefix ‘def’ is given function definition font locking by default

that's a bit of an idiom. i have a lot of defmacros 🙂

I'ts 1 line with lexical binding t

(defun complement (f)
  "Returns the function that has the
opposite truthyness of `f`."
  (lambda (&rest r) (not (apply f r))))
