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.

Close the parent fold
Select closed fold and next line
:foldc! - closes all folds in range `<,`> (read :h foldc)

You can obviously map that sequence.

If you substitute step 3 by simple typing zC it also does the trick, doesn't it? – Manuel Schmidt Jun 30 '18 at 16:15
It actually folds child folds, but it also folds parent ones, doesn't it? – Manuel Schmidt Jun 30 '18 at 17:33

I rolled my eyes when you mentioned `:foldclose`, but to my surprise `:%foldc!` actually works. That is certainly worthy of an upvote. – Braden Best Sep 07 '18 at 22:17

I did not actually find an exact answer to this question, but a few commands than could be a workaround in some cases are:

zM: Closes recursively the root folds and all their children
zm: Increases the foldlevel by one, i.e. closes the innermost level of folds that are not yet folded

The opposite commands are:

zR: All folds are open
zr: Decreases the foldlevel by one

`zM` is for closing all folds, not doing what you describe here, it is what `zC` does. – jdhao Jun 13 '23 at 14:22
@jdhao, `zC` closes all folds **under the cursor** recursively. `zM` closes **all** folds, but I wanted to remark that children's folds are closed recursively as well, not just the root level. – Manuel Schmidt Jun 17 '23 at 07:46

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:

go to a line in father folding level
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:

Select the range visually.
: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.

I had this need for a long time too, and what I found out as the closest solution was using zM to close all folds recursively and then zv to reopen the line at cursor previous position (before closing folds). Maybe it helps.

Regards.
