[vim/vim] vim's '%' command should ignore comments (Issue #20329)

[rendcrx]

rendcrx created an issue (vim/vim#20329)

Steps to reproduce

int main()
{
	// {
}

1. vim --clean a.c
2. move cursor to '{' of line 2
3. %

Expected behaviour

Vim should ignore characters inside comments and jump to the matching '}' of the next line.

I can't use % in ‘vim/src/cindent.c:2136‘ to jump, pressing % does nothing. I guess the reason is Vim doesn't ignore the '{' of line 2690.

Vims % matching is simplistic and does not consider comments. User the matchit plugin for more advanced % matching. Closing as duplicate

packadd matchit

Thank you. But my theme has syntax match, it seems conflict with matchit. Do you know how to deal? I try to use matchadd to instead syntax match, but it will lead to highlight characters inside comments.

After using the vimscript above, matchit also fails to bracket-match in the aforementioned C files.
