im a emacs noob and i want to use the rainbow-mode on doom emacs to
highlight columms of colors. When i launch the command (rainbow-color)
it shows it, but only in that specific file and not others, and
everytime i open doom emacs, i have to launch again the command


how can i do that a module always starts?, be consistent?. Thanks

This might not be the ideal way to do it, but you could try something
like the following in your config.el

     (add-hook 'buffer-list-update-hook 'rainbow-mode)

You can also do `(add-hook! (prog-mode-hook text-mode-hook) #'rainbow-
mode)` though I do not recommend this as `rainbow-mode` can produce a
lot of overlays and slow your Emacs to a crawl. Instead, I recommend
enabling it on a per-file or per-directory basis.

I use doom and this is what I have in my config.

    (add-hook! org-mode 'rainbow-mode)
    (add-hook! prog-mode 'rainbow-mode)

It will hook rainbow-mode into any programming language mode and org-
mode which covers most use cases.

This could work but I haven't tested it.

TIL `buffer-list-update-hook` so that's neat.

See also `evil-local-mode-hook` that can be very convenient.
