I have an operator function that yanks double quotes or single quotes, ciq works fine because I want to be inside the quotes but when I do yaq (yank a quote) I don't want to move to the place where the quote is at. Seems like an easy task to just get back to the previous cursor position after the yank? I have tried the following things:

  1. Tried setting the cursor position with an TextYankPost.
  2. Tried setting marks in the actual mapping, probably not allowed cause it's expecting a motion.
  3. Tried restoring cursor position from the function with setpos(). Probably don't work cause it's inside of the function.

This does not work maybe cause it's inside the function.

let saveCur=getcurpos()
execute "normal! mz"
call setpos('.',saveCur)
 exe "normal! `z"
if a:operator == 'y' | call setpos('.',saveCur)  | endif

Not too sure if a call back function would work. Jumps wont work cause exe "normal 12lv" is not a jump. This is the function. I know it's probably overkill when I could have just done exe normal! ?\% but I learned a lot of vimscript from it. Any suggestions are welcome. Thanks

function! QuoteTextObject(whole) abort

let char=a:whole ? 'a' : 'i'
let regex= '\v("|' . "').{-}".'("|' . "')" 
let res=matchstrpos(strcharpart(getline('.'),col('.')-1),regex)
let backRes=matchstrpos(strcharpart(getline('.'),0),regex)
let [start,stop]=copy(res)->remove(1,2)
let [bstart,bstop]=copy(backRes)->remove(1,2)
let offset=stop-start-1
let boffset=bstop-bstart-1

"if nothing was found forward or backward return
if res == ['',-1,-1] && backRes == ['',-1,-1] |call feedkeys("\e")| return 0 | endif

"find match backwards
if res == ['',-1,-1]  
    echom 'no match found forward'
    execute "normal! 0"
    let start=bstart | let offset=boffset
endif

if char == 'a' | execute 'normal! '.start.'lv'.offset.'l' | return 0 |endif
let offset=  eval(offset-2) > 0 ? eval(offset-2).'l':''
let icmd='normal! '.eval(start+1).'lv'. offset
if char == 'i' | execute icmd | return 0 |endif

endfunction

  • I wouldn't be surprised if the operator execution context is independent from the calling context. If you save position from within the function in a global variable and restore from that upon return the result is as expected so maybe there's a solution based on that. BTW, I recommend winsaveview() and winrestview() for state save/restore.

  • (Or save the state before calling the function. I suspect, though, that there's an even better way to do this. If I can't think of it someone else surely will.)

  • @BLayer How do I winrestview(g:saveCur) from outside of the function or outside the mapping calling it ? Unless I set a timer or something in the function that would later call another function. I don't think I could include the call in the mapping. Like timer_start() or something.

  • Perhaps you can't. I was basically thinking out loud and I assumed there was a context switch at the function call (which, in retrospect, isn't a good theory). But if the scope of the switch is wider (or there's an additional switch around mapping) then, indeed, that's a higher mountain to climb. Your timer idea would probably work but let's hope there's a cleaner solution to be had.

  • @BLayer yea the timer does work thanks. I kinda like it like that cause I can see that it actually yanking something, I have it set to 1ms. The worst thing that can happen at 1ms is that I won't get back to my position.

Reset to default

What took care of it was calling a call back with timer_start() with a 1ms delay to restore the cursor position.
