Not so much an issue as an idea.

Mihara commented 2 years ago

With Emacs in particular (and with kitty where I picked up the technique) you don't have to use the patched nerd fonts: you can override part of the fontset with another font that only contains the icon glyphs.

This way, you could potentially avoid installing the fonts from all-the-icons altogether and avoid using patched fonts. This appears to work well with all-the-icons-nerd-fonts as it is now.

This is how I do it:

Install https://github.com/ryanoasis/nerd-fonts/blob/master/src/glyphs/Symbols-2048-em%20Nerd%20Font%20Complete.ttf

Do magic with set-fontset-font:


(defun mihara/attach-nerd-font (&rest maybe-a-frame)
"Attach the Symbols Nerd Font with `set-fontset-font'.
Parameter MAYBE-A-FRAME is actually ignored."
;; It's only needed so that this function runs in newly created frames,

Seems like a cool idea. It would probably simplify code-points and make it easier to customize but this only really works with somthing like nerd-fonts (if I'm understanding it correctly). There's still some font glyphs that aren't in nerd fonts (like emacs for one :cry:) so we still need something like all-the-icons that can work across multiple (perhaps conflicting) fontsets. Once this does happen though I see no issue with your suggestion, you might wanna raise it on all-the-icons as well when that happens.

Mihara commented 2 years ago

Technically, you could just use all the fonts all-the-icons installs and stitch them all together this way into the base font, as well. I am just not up to tracking down all the codepoints involved, right now, as even fishing them out of a single ttf file was a task that is slightly above my current understanding of fonts.
