I have this setting in vim
foldmarker={{{,}}}
commentstring=/*%s*/
foldmethod=marker
I want to create new marker using zf, which does work for
void foo(void bar) {
}
when I selected that and press zf, I get
void foo(void bar) {/*{{{*/
}/*}}}*/
so far so good. However when function definition contains pointer, like in
void foo(void * bar) {
}
I do get
void foo(void * bar) {{{{
}/*}}}*/
which is wrong. How can I configure vim to work properly even in second case?
That strange behavior is caused by the default value of the :help 'comments' option, in particular the mb:* part.
:help format-comments explains
To avoid recognizing "*ptr" as a comment, the middle string includes the 'b' flag.
Unfortunately, the way you write the pointer (which whitespace after the *) defeats this heuristic, and Vim detects the * as a middle piece of a three-piece comment (Vim doesn't verify that there's actually a start piece before it), assumes the fold start already is part of a comment, and therefore skips adding the 'commentstring' there.
To fix this, either adapt your coding style (write void *bar), or modify the 'comments' option, e.g. by removing (or refining if you use it) the middle piece part:
setlocal comments-=mb:*
If you need to keep middle pieces and correct manual folds, you'd have to write a small wrapper mapping around zf that temporarily changes the option.
