Get the value of window-local variable {varname} in window {winnr} in tab page {tabnr}. When {varname} is empty a dictionary with all window-local variables is returned. When {varname} is equal to "&" get the values of all window-local options in a |Dictionary|. Otherwise, when {varname} starts with "&" get the value of a window-local option. Note that {varname} must be the name without "w:". Tabs are numbered starting with one. For the current tabpage use |getwinvar()|. {winnr} can be the window number or the |window-ID|. When {winnr} is zero the current window is used. This also works for a global option, buffer-local option and window-local option, but it doesn't work for a global variable or buffer-local variable. When the tab, window or variable doesn't exist {def} or an empty string is returned, there is no error message. Examples: :let list_is_on = gettabwinvar(1, 2, '&list') :echo "myvar = " . gettabwinvar(3, 1, 'myvar') To obtain all window-local variables use: gettabwinvar({tabnr}, {winnr}, '&') Can also be used as a |method|: GetTabnr()->gettabwinvar(winnr, varname)
