Moving over folds has undesirable behavior

[zirrostig]

When dragging text over a closed fold the selection gets broken, making dragging not work as expected.

Turns out vim is doing exactly what is expected, it just doesn't auto expand folds when moving text into them, causing a lot of issuses with continued schlepping.
I'm looking into having schlepp auto-expand folds when moving into them.

For me, it also closes the fold when I schlepp text within an opened fold.

@Ahg4goo9 I think this is an issue with vim itself. Try moving a line in an open fold with :m+ and you'll get the same result.

Kind of a hack, but I did this and it seems to be working ok:

vmap <Plug>SchleppFix zagv
vmap <left>  <Plug>SchleppLeft<Plug>SchleppFix
vmap <right> <Plug>SchleppRight<Plug>SchleppFix
vmap <up>    <Plug>SchleppUp<Plug>SchleppFix
vmap <down>  <Plug>SchleppDown<Plug>SchleppFix

Edit: oops, I spoke too soon… it only works when using linewise visual mode. :/

Edit 2: It's getting even more hacky and there are plenty of problems, but in case anybody's interested, this is what I got so far to make it usable with folds. It's better than nothing, since I use them everywhere.

function! SchleppDetect(direction)
    let mode = mode()
    let command = ""
    if mode ==# 'v'
        let command .= "\<c-v>"
    endif
    let command .= "\<Plug>Schlepp" . a:direction
    if mode ==# 'V'
        let command .= "zRgv"
    endif
    return command
endfunction

vmap <silent> <expr> <Left> SchleppDetect("Left")
vmap <silent> <expr> <Right> SchleppDetect("Right")
vmap <silent> <expr> <Up> SchleppDetect("Up")
vmap <silent> <expr> <Down> SchleppDetect("Down")
