[HOWTO] Disable rainbow-delimiters

[Shooooooooo]

What are you trying to achieve?
Trying to disable rainbow-delimiters and use a different parentheses highlighter.

What have you tried?
I have set package.el to:
(package! rainbow-delimiters :disable t)
and doom refresh.

Now, I am getting this warning/error if I open up my C++ file:
File mode specification error: (void-function rainbow-delimiters-mode)

May I know if there is a more elegant way of disabling rainbow-delimiters? I could not find and reference of doing so. Thanks!

You should not disable core packages with package!. If they are in core, the rest of Doom assumes it is always present. Instead, remove rainbow-delimiters-mode from c-mode-common-hook:

(after! cc-mode
  (remove-hook 'c-mode-common-hook #'rainbow-delimiters-mode))

I will be moving some of these packages into modules soon.

Thanks for pointing this out! I am trying to migrate some of my settings from my vanilla Emacs setup to doom. Really like doom-emacs so far!
I have another 2 questions during the migrate process.

1. What is the recommended way for dynamically choose whether to load a module?
   e.g. Only load doom's modeline if running in GUI. Otherwise, use some other modeline package.
   The only way I can think of currently is to disable the module, and declare and configure the doom-modeline package manually. But, I guess that will lose some stuff in the modeline module?

2. After enabling vterm module and load up a terminal, my modeline disappears for the terminal buffer. Is it by design?

Thanks again!

What is the recommended way for dynamically choose whether to load a module?

It depends on the condition. Whenever your module list (i.e. doom! block) changes, you have to run doom sync (same as doom refresh). If the condition could change from startup-to-startup, without running doom sync, then it won't work.

If the condition is more stable, e.g. what OS you're on, or what version of Emacs you're running, you can use :if, :when, :unless and :cond as demonstrated here.

Only load doom's modeline if running in GUI. Otherwise, use some other modeline package.

In this case, you could add this to your ~/.doom.d/config.el:

(unless (display-graphic-p)
  (remove-hook 'after-init-hook #'doom-modeline-mode))

After enabling vterm module and load up a terminal, my modeline disappears for the terminal buffer. Is it by design?

Yes. To reverse this:

(after! vterm
  (remove-hook 'vterm-mode-hook #'hide-mode-line-mode))
