This plugin provides to tell you to which window for jumping when :cnext, :cprevious and selecting an error in the quickfix window.

Functions

qfprediction#get([{n}])

If {n} is 0 or not specified, returns which window for jumping when selecting an error in the quickfix window.
If {n} is 1, returns which window for jumping when :cnext.
If {n} is -1, returns which window for jumping when :cprevious.

" Will open a file of the error at the window of the return value when selecting an error in the quickfix window.
echo qfprediction#get()
" -> { 'winnr': 1, 'tabnr': 2, }


" Will open a file of the error at new window when `:cprevious`.
echo qfprediction#get(-1)
" -> { 'split': v:true, }


" Will open a file of the error at new window when `:cnext`.
echo qfprediction#get(1)
" -> { 'split': v:true, }


" Could not predict a window!
echo qfprediction#get()
" -> {}

The following is an example of using qfprediction#get().

function! TabLineSub(n) abort
	let x = qfprediction#get(a:n)
	if has_key(x, 'tabnr') && has_key(x, 'winnr')
		if tabpagenr() == x['tabnr']
			return printf('win(%d)', x['winnr'])
		else
			return printf('win(%d) of tab(%d)', x['winnr'], x['tabnr'])
		endif
	elseif has_key(x, 'split')
		return 'split'
	else
		return '?'
	endif
endfunction
function! TabLine() abort
	let curr = TabLineSub(0)
	let next = TabLineSub(1)
	let prev = TabLineSub(-1)
	return printf('[qfprediction] curr:%s, cnext:%s, cprev:%s', curr, next, prev)
endfunction
set showtabline=2
set tabline=%!TabLine()
augroup qfprediction
	autocmd!
	autocmd WinEnter * :redrawtabline
augroup END
