I am editing a HTML document (filetype=html) in vim. foldmarker is set to {,}, foldmethod to marker and commentstring to <!--%s-->.

When I visually select a region and use zf to create a folding, vim inserts a { at the beginning and a } at the end of the region. However, with my settings, I expected vim to insert <!--{--> and <!--}-->, respectively.

Why is vim ignoring commentstring when folding?

  • It works for XML, but doesn't work for HTML, indeed. But if you setlocal comments= then it will work. – Maxim Kim Dec 6 at 15:45
  • cannot reproduce. Please try to come up with a minimal example starting with vim --clean – Christian Brabandt Dec 6 at 16:05
  • Sh, it seems to be caused by the n:> flag of the 'comments' option, however, that is not included in the html filetype (so it happens, if you manually override it afterwards). Please check where you set this – Christian Brabandt Dec 6 at 16:13
  • @ChristianBrabandt I can reproduce it with comments=s:<!--,m: ,e:--> which is set by html filetype. – Maxim Kim Dec 6 at 16:22
  • @ChristianBrabandt and it happens when you try to do it on a paragraph for example, but don't start and end on empty lines. Just do zfip. – Maxim Kim Dec 6 at 16:24

This answer probably should be deleted. Answering here to show it @ChristianBrabandt.

It is kind of strange but for some text it works, for the other it doesn't:

enter image description here

And if you change the first paragraph to:

blablabla a
lkjsdlfkj
lksjdflksdj
lksjdflksja

Then it will not work for the first row. Looks like if there are more than 1 word on the line it doesn't insert commentstring.

  • Looks like a bug to me and seems to be caused by v8.0.0453 if my short testing was correct. Can someone create an issue for that? – Christian Brabandt Dec 6 at 17:09
  • github.com/vim/vim/issues/3670 @ChristianBrabandt could you step in and comment there about vim version caused the issue? – Maxim Kim Dec 6 at 17:19
  • should be fixed now – Christian Brabandt Dec 9 at 18:47
  • @ChristianBrabandt, yes I have checked it with the new build -- it is fixed. – Maxim Kim Dec 9 at 19:12
