Fonts

Installing fonts on NixOS

NixOS has many font packages available, and you can easily search for your favourites on the NixOS packages site.

Despite looking like normal packages, simply adding these font packages to your environment.systemPackages won't make the fonts accessible to applications. To achieve that, put these packages in the fonts.fonts list instead.

For example:

fonts.fonts = with pkgs; [
    noto-fonts
    noto-fonts-cjk
    noto-fonts-emoji
    liberation_ttf
    fira-code
    fira-code-symbols
    mplus-outline-fonts
    dina-font
    proggyfonts
];

Imperative installation of user fonts

This is useful for quick font experiments.

Example: Install SourceCodePro-Regular.

font=$(nix-build --no-out-link '<nixpkgs>' -A source-code-pro)/share/fonts/opentype/SourceCodePro-Regular.otf
cp $font ~/.local/share/fonts
fc-cache
# Verify that the font has been installed
fc-list -v | grep -i source

Set multiple fonts for different languages

If you are not an english native user and want to use another languages alongside english, you may want to set appropriate fonts for each language in your whole os. In nixos, it's so easy. Imagine i'm a persian user and i want to set "Vazir" font to persian texts and "Ubuntu" font for english texts. Just put these lines into your configuration.nix:

 #----=[ Fonts ]=----#
  fonts = {
 	enableDefaultFonts = true;
    	fonts = [ 
          pkgs.ubuntu_font_family

          # Persian Fonts
          pkgs.vazir-fonts
	];

	fontconfig = {
	    penultimate.enable = false;
	    defaultFonts = {
		serif = [ "Vazir" "Ubuntu" ];
	  	sansSerif = [ "Vazir" "Ubuntu" ];
	  	monospace = [ "Ubuntu" ];
	    };
	};
  };

Troubleshooting

What font names can be used in fonts.fontconfig.defaultFonts.monospace?

Those that fontconfig will understand. This can be queried from a font file using fc-query.

$ cd /nix/var/nix/profiles/system/sw/share/X11-fonts
$ fc-query DejaVuSans.ttf | grep '^\s\+family:' | cut -d'"' -f2

Adding personal fonts to ~/.fonts doesn't work

The ~/.fonts is being deprecated upstream. It already is not working with NixOS.

The new preferred location is in $XDG_DATA_HOME/fonts, which for most users will resolve to ~/.local/share/fonts
