Question

Vim’s wrap option is local to the window, not buffer and if I would like to have a buffer specific map I can do that via map-<buffer>.

So putting the two together, if I want a wrap-mode specific mapping, how can I achieve map-<window> functionality?

Thanks!

Answer 1

As a window can display different buffers at various times, it doesn’t make sense to have window-local mappings.

I think what you’re really asking for is how to do different things in a mapping depending on a window-local setting like 'wrap'. You can access the local 'wrap' setting via the &l:wrap special variable, like in this example:

:nnoremap <expr> j &l:wrap ? 'gj' : 'j'
