Re: Keepjumps for windows

Hello,

I really like the command CTRL-Wp to jump to the previous window.  In
one of me plugins I jump to another window and come back.  This
unfortunately destroys the CTRL-Wp.  How to make it work (except of
going through the window that CTRL-Wp points to and coming back through
it).  There is keepjumps and keepalt modifiers, I haven't seen something
like this for windows.  Any ideas?

Best,
Marcin

I do this:

let t:lastWindow       = winnr()

" When changing tabs, the WinLeave also gets called, changing the last window to what is actually the current window. So, we store the previous last window in
" the WinLeave autocommand and, if the WinLeave was the result of a TabLeave, restore it in the TabLeave.
augroup LastTab
  au!
  au TabLeave * let t:lastWindow = t:oldLastWindow
  au WinLeave * let t:oldLastWindow = t:lastWindow | let t:lastWindow = winnr()
  au TabEnter * if ( !exists( "t:lastWindow" ) ) | let t:lastWindow = winnr() | endif
augroup END

function! ToggleWindow( ... )
  let windowNumber = exists( "a:1" ) ? a:1 : t:lastWindow

  if ( windowNumber == winnr() )
    let windowNumber = windowNumber - 1
  endif

  if ( windowNumber > winnr( '$' ) )
    let windowNumber = 1
  elseif ( windowNumber < 1 )
    let windowNumber = winnr( '$' )
  endif

  execute windowNumber . 'wincmd w'
endfunction

You could then set a mapping or add a flag to the autocommand to NOT change the t:lastWindow and then set it before you move about.

I have a normal mode mapping to :call ToggleWindow()<CR>

Hope this helps,
