kitty does not properly detect LiterationMono Nerd Font #4374

Closed Dieterbe closed 2 years ago

Dieterbe commented 2 years ago

Hello, first of all, thanks for a wonderful terminal program.

I have the LiberationMono Nerd Font installed:

~ ❯❯❯ fc-match 'LiterationMono Nerd Font'
Literation Mono Nerd Font Complete.ttf: "LiterationMono Nerd Font" "Book"
~ ❯❯❯ fc-list 'LiterationMono Nerd Font'
/usr/share/fonts/TTF/Literation Mono Bold Italic Nerd Font Complete.ttf: LiterationMono Nerd Font:style=Bold Italic
/usr/share/fonts/TTF/Literation Mono Italic Nerd Font Complete.ttf: LiterationMono Nerd Font:style=Italic
/usr/share/fonts/TTF/Literation Mono Bold Nerd Font Complete.ttf: LiterationMono Nerd Font:style=Bold
/usr/share/fonts/TTF/Literation Mono Nerd Font Complete.ttf: LiterationMono Nerd Font:style=Book
~ ❯❯❯

The problem can be reproduced using this minimal kitty.conf

font_family      LiterationMono Nerd Font
font_size 11.0

When I run the following script, it does seem to use the proper font, but only for the "base version", underline and strikethrough (which didn't appear in fc-list/fc-match). the bolds and italics don't seem to work (these did show up)

See screenshot below.

Any idea why the bold and italics don't render correctly?

BTW, when I start kitty with debug-font-fallback, it doesn't seem to mention the base font. I'm not sure how useful this parameter is for this case, as it explicitly aims to debug "fallback glyhps" not in the main font. but wanted to mention it anyway.

Press Ctrl+Shift+F6 (cmd+option+comma on macOS) in kitty, to copy debug output about kitty and its configuration to the clipboard and paste it here.

this doesn't do anything for me.

On older versions of kitty, run kitty --debug-config instead

~ ❯❯❯ kitty --debug-config
Unknown option: --debug-config
~ ❯❯❯ kitty --version

Anyway, I have provided the minimal config.

I have also tried setting the italic font explicitly like so:

font_family      LiterationMono Nerd Font
italic_font      LiterationMono Nerd Font:style=Italic

Seems like fc-match recognizes it properly:

~ ❯❯❯ fc-match 'LiterationMono Nerd Font:style=Italic'
Literation Mono Italic Nerd Font Complete.ttf: "LiterationMono Nerd Font" "Italic"

but again, using the test script, it doesn't show the italic text

kovidgoyal commented 2 years ago

The font name is Liberation Mono not Literation Mono. And don't use patched fonts, just install the nerd fonts separately. kitty will use it automatically and you can tell it to explicitly as well using symbol_map in kitty.conf.

Dieterbe commented 2 years ago

And don't use patched fonts, just install the nerd fonts separately

I don't understand this. Nerd Fonts are patched fonts. Any nerd font installed is a patched font. Perhaps what you mean is to install liberation-mono and separate font packages to provide Font Awesome, Devicons, Octicons and Material Design icons ?

I was specifically recommended elsewhere to just go with nerd-fonts as it removes the complication of using multiple fonts to get the icon packages.

(the name of the nerd font version is Literation, as can be seen in fc-match and fc-list, and is explained further on https://github.com/ryanoasis/nerd-fonts/blob/master/patched-fonts/LiberationMono/font-info.md )

kovidgoyal commented 2 years ago

The nerd fonts are available as a separate standalone font, look in its releases page. Use that.

And if you want to find the names of fonts to use in kitty.conf, use kitty +list-fonts not fc-list.

xsrvmy commented 2 years ago

Were nerd fonts downloaded from master branch or 2.1.0? The master branch is bugged right now.

mattia-marini commented 3 months ago

Just for future reference, you should got to NerdFonts github, got to the latest release and search for "NerdFontSymbolsOnly". You should find everything here
