A.k.a (add-hook 'window-configuration-change-hook #'ruler-mode)

But to tell you the truth, I have no idea why you'd want to re-enable
ruler-mode every time the window-config changes.

ruler-mode is a buffer-local minor mode, so you'd normally install it
into a major-mode hook so as to enable it in those buffers where you
need it.

I'd stay away from a fiddly low-level function like `set-face-attribute`
and change face settings via Custom instead (or if you really want to
avoid Custom, use something like `face-spec-set`).
