Vim folding - Close all children recursively under cursor

Question

I know how to open all folds under cursor with zO.

But how to do reverse?

I want something like za does, but also with recursivity.

PS. I know there is zC, but it closes all parent folds in relation to current line and I want to close children.

Answer 1

Note: the question deals with only current children. I.e to close/open till current fold level, and NOT all the way as zC, zO, zA, zM, zR.

Fold only current children recursive

zx folds: Undo manually opened and closed folds: re-apply 'foldlevel', then do "zv": View cursor line. Also forces recomputing folds. This is useful when using 'foldexpr' and the buffer is changed in a way that results in folds not to be updated properly.

zc close folded text

I think you want to combine both:

1. go to a line in father folding level
2. Press (in normal mode) zxzc. Or remap it: nnoremap zxc zxzc

Unfold only current children recursive

Btw: to do the opposite, open recursive all children: zczA

Un-/Fold only selected recursive

Or to open/close a desired range of folds recursive:

1. Select the range visually.
2. :foldo (as previous link) or :foldc (as @majkinetor answer).

Tips to select the range visually:

]z jump to end of current open fold.
[z jump to beginning of current open fold.
zj moves the cursor to the next fold.
zk moves the cursor to the previous fold.
