How to match brackets in matchadd command regular expression?

Question

I want to highlight breakpoint() - including brackets as keywords in Python files.

I have added these two commands to my .vimrc:

highlight link PyBreakpoint Keyword        
call matchadd("PyBreakpoint", '\<breakpoint\(\)\>')

However, only the breakpoint word gets matched and highlighted. How could I match the brackets also in order to apply the color to them also?

I think by default \( creates groups. Try :help pattern. Also, you might want to use after/syntax/python.vim and the syntax machinery; matches are somewhat limited — D. Ben Knoble, Commented Mar 2, 2021 at 14:58

Try removing the backslashes from the parens. This is what works for me.

call matchadd("PyBreakpoint", 'breakpoint()')

with example file:

this
that
breakpoint()
other
another

I have ended up using call matchadd("PyBreakpoint", '\sbreakpoint()\s').
