reads as a string concatenation. I'm not sure how you'd expect a syntax highlighter to make it look like anything else, to be honest
One possible syntax highlighting scheme: - f' and ' are hilighted in pink, along with any plain text content of the string. - - Incidentally, any backslash escapes, not shown here, are highlighted in orange. - { and } are hilighted in blue; along with format specifiers, maybe, or maybe they get another color. - The code inside the expression is highlighted in orange. - Any keywords, builtins, constants, etc, within the expression are highlighted in their usual colors. - - In this example in particular, ' + ' and 0 are highlighted in pink. A pink + is a character within a string, a gray or orange + is an operator. In terms of Vim's basic syntax groups: - C = Constant [pink] - P = PreProc [blue], by precedent as use for the $(...) delimiters in sh) - S = Special [orange], by precedent as use for the content within $(...) in sh, and longstanding near-universal precedent, including in python, for backslash escapes. These would, naturally, have separate non-basic highlight groups, in case a particular user wanted to change one of them. f'foo {x.partition(' + ')[0]:aaa} bar\n' CCCCCCPSSSSSSSSSSSSCCCCCSSCSPPPPPCCCCSSC
(given that you're arguing *not* to highlight the whole of the content of the f-string the same way).
I'm not sure what you mean by "the same way" here, I haven't followed the discussion closely enough to know what statement by whom you're referring to here.
