Changing colour of ruler-mode-current-column

Changing colour of ruler-mode-current-column

[uzibalqa]

I am using ruler-mode and would like to change the background and foreground colour of the cursor indicator.

Had a go but ruler-mode-current-column is not a face.

(set-face-attribute 'ruler-mode-current-column nil
  :background "#ff4500" :foreground "#ffffff")

Yes, ruler-mode-current-column _is_ a face, and the above works for
me: the colors of the current-column indicator change.

There exists the possibility of needing this (require 'ruler-mode)

I evaluated the above set-face-attribute form after turning on
ruler-mode.

I have the following setup

(defun typex-ruler ()

  "Customisation for ruler."

  (interactive)

  (require 'ruler-mode)

  (add-hook 'window-configuration-change-hook (lambda () (ruler-mode 1)))

  (set-face-attribute 'ruler-mode-current-column nil :background "#ff4500" :foreground "#ffffff") )

Is there a recommended better way to do it?

Better from what POV?  Does the above fail to work for some reason?

It works, everything is fine.

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`).
