import { fn } from "https://deno.land/x/ddu_vim@v4.0.0/deps.ts";
const { winnr } = fn;
The result is a Number, which is the number of the current window. The top window has number 1. Returns zero for a popup window.
The optional argument {arg} supports the following values:
$ the number of the last window (the window
count).
# the number of the last accessed window (where
CTRL-W_p goes to). If there is no previous
window or it is in another tab page 0 is
returned.
**{N}**j the number of the Nth window below the
current window (where CTRL-W_j goes to).
**{N}**k the number of the Nth window above the current
window (where CTRL-W_k goes to).
**{N}**h the number of the Nth window left of the
current window (where CTRL-W_h goes to).
**{N}**l the number of the Nth window right of the
current window (where CTRL-W_l goes to).
The number can be used with CTRL-W_w and ":wincmd w"
:wincmd.
When {arg} is invalid an error is given and zero is returned.
Also see tabpagewinnr() and win_getid().
Examples:
let window_count = winnr('$')
let prev_window = winnr('#')
let wnum = winnr('3k')
Can also be used as a method:
GetWinval()->winnr()
