The wiki has an example for completion with nerd fonts which doesn't work

[chookity-pokk]

I wasn't sure if this should be a bug report or not but here has an example for using nerd-fonts.el and when I try it I get Symbol's function definition is void: all-the-icons-nerd-seti. I downloaded nerd-fonts.el and loaded it into my path as well as required it.

Here is my config:

(require 'company)
(require 'all-the-icons)
(require 'nerd-icons)
(add-to-list 'load-path "~/.emacs.d/lisp/nerd-fonts.el")
(require 'nerd-fonts)

(use-package all-the-icons-nerd-fonts
  :after all-the-icons
  :demand t
  :config
  (all-the-icons-nerd-fonts-prefer))

(defface company-icon+ `((t (:inherit company-tooltip)))
  "Face for the margin icon in the `company-mode' tooltip."
  :group 'company-faces)

(defface company-current-icon+ `((t (:inherit company-tooltip-selection)))
  "Face for the margin icon for the current candidate in the `company-mode' tooltip."
  :group 'company-faces)

I think in that example you still need all-the-icons installed. But you could rewrite it without, IIUC that's what the text is saying.

@mohkale could correct me if I'm wrong.

[chookity-pokk]

That is working inside of org mode buffers (though the only option seems to be Tux haha). Inside of a code buffer though I get nothing. I have a nerd font as my default font and have installed fonts via nerd icons and all the icons.

[chookity-pokk]

Though if I'm totally honest, I am fine if this doesn't work because I only started using it because none of my icons in company were showing which has since been solved. So, no one needs to spend a ton of time on this is what I'm saying!

[dgutov]

It probably means that you need to install (EDIT:) some other fonts, in addition to Emacs packages, like in https://github.com/ryanoasis/nerd-fonts#font-installation

I only started using it because none of my icons in company were showing which has since been solved

Great!

[dgutov]

that you need to install (EDIT:) some other fonts

In particular, the md suffix refers to Material Design, IIUC.

[mohkale]

To clarify you do still need all-the-icons installed when using all-the-icons-nerd-fonts but that error message seems more like all-the-icons-nerd-fonts hasn't been loaded. When I get a chance I'll try double checking the snippet on the wiki still works, although since the reporters issue has been solved I won't look into it immediately :-).
