Question

I am currently editing a C++ file with twp function similar to

int func_name_1(int param) {
   do_stuff();
   and_more();
}

int func_name_2(int param) {
   do_different_stuff();

   STRUCT_TYPE s = {5, 8, 10, 12};
   do_something_with(s);
}

If I do a zc on the word func_name_1, vim folds the function, as expected, so that it now looks like

int func_name_1(int param) {--------------------

On func_name_2 however, the function is folded like so:

int func_name_2(int param) {---------------------
   do_something_with(s);
}

which is not exactly what I want. For some reason the opening and closing {} on one line seem to disturb the folding algortithm.

If someone knows how I can get a “better” folding, I’d appreciate any hinter into the right direction.

Edit the options that I believe are relevant for this problem are set in my buffer like so

set foldmarker={,}
set foldmethod=marker
set foldtext=getline(v:foldstart)

Edit II: If I change the line with the opening and closing {…} to STRUCT_TYPE s = { 5, 8, 10, 12}; (Note the space after the {), then the folding works as expected.

Answer 1

Oh…. I see….

:help fold-marker tells me: Markers can have a level included [..] The following number specifies the fold
level

So, the 5 immediatly after the { specified the fold level, which messed things up.
