I would like to open all folds in a buffer recursively apart from folds which contain just text and no further folds.

I know that zO opens all folds in a buffer but as explained this is different from what I would like to achieve. Furthermore it will also not help to set a specific fold level because the depth in the fold hierarchy is very different.

Is there a way to achieve what I want?

Try this:

zM
:folddoclosed if foldlevel('.') < foldlevel(line('.')+1) | exe 'norm! zo' | endif

Close all folds. Then, iterating over all lines in closed folds, check if the subsequent line has a greater foldlevel. If so, unfold the current line.

  • I tried to keybind the solution like this: nnoremap ,z :%foldc!<CR>:folddoclosed if foldlevel('.') < foldlevel(line('.')+1) | exe 'norm! zo' | endif. Unfortunately it does not work and I get some error messages E490 that there are no folds. – Cutú Chiqueño May 23 '17 at 8:42
  • ok, I found out that I need to substitute | with <bar> in a vimrc file. Now it works – Cutú Chiqueño May 23 '17 at 9:04
  • You can escape it too: \|. – Antony May 23 '17 at 9:36
