I'm writing a syntax highlighting rules in Vim for Clojure, or another Lisp where (fn ...) occurs mostly for function calls. I'm stuck at highlighting the first word of a function call, i.e. the function reference. Below is a demo of where I'm at:
As you can see, the first word in the function calls (str in (str a b c d)) is highlighted. However, the first element in the literal lists (1 in '(1 2 3)) is also highlighted, which is unintentional. To emphasize, both literal lists have their first elements highlighted, which is wrong.
Below is the syntax rule that does this highlighting:
syn match lispFunc "'\{0}\((\)\@<=\<.\{-1,}\>?\{0,1}"
Here's how I understand this rule:
'\{0}: the character'must match 0 times;\((\)\@<=: the character(must match, but not be captured;\<.\{-1,}\>: this matches one word (\<and\>represent beginning and end of a word);?\{0,1}: if there is a?character at the end of the word, then consider it part of the word: e.g. the highlighted?inlist?in the picture.
I've experimented quite a bit, but I can't seem to make the first two sub-rules work together.

Clojure is very well behaved in this sense, Racket a bit less so, but I prefer the noise that this will generate, over the noise of dictionary based function highlighting. – Dominykas Mostauskissyn match lispFunc "\(\('\)\@<!(\)\@<=\<.\{-1,}\>?\{0,1}"– Wiktor Stribiżew
