NixOS 处理字体就像处理系统中许多不同部分一样：除非明确标记为环境的一部分，否则它们不会出现在环境中。本指南涵盖字体的安装、配置和故障排除。

在 NixOS 上安装字体
NixOS handles fonts like it handles many different parts of the system: they are not in an environment unless explicitly marked to be part of it. This guide covers the installation, configuration and troubleshooting of fonts.

NixOS 有许多可用的字体包，你可以轻松地在这里搜索并使用他们： [https://search.nixos.org/packages NixOS packages site].  


<span lang="en" dir="ltr" class="mw-content-ltr">Despite looking like normal packages, simply adding these font packages to your <code>environment.systemPackages</code> won't make the fonts accessible to applications. To achieve that, put these packages in the <code>[https://search.nixos.org/options?channel=unstable&show=fonts.packages&from=0&size=50&sort=relevance&type=packages&query=fonts.packages fonts.packages]</code> NixOS options list instead.</span>
尽管这些字体包看起来与普通包无异，但仅将它们添加到 `environment.systemPackages` 并不会让应用程序能够访问这些字体。要实现这一点，应将它们放入 NixOS 的 `[https://search.nixos.org/options?channel=unstable&show=fonts.packages&from=0&size=50&sort=relevance&type=packages&query=fonts.packages fonts.packages]` 选项列表中。

=== Shorthands for fonts ===
=== 启用预置字体集合 ===
* <code>fonts.enableDefaultPackages</code>: when set to <code>true</code>, causes some "basic" fonts to be installed for reasonable Unicode coverage. Set to <code>true</code> if you are unsure about what languages you might end up reading.
* <code>fonts.enableDefaultPackages</code>：当设为 <code>true</code> 时，会安装一些“基础”字体以提供合理的 Unicode 覆盖范围。如果您不确定自己可能会阅读哪些语言，可将其设为 <code>true</code>。
* <code>fonts.enableGhostscriptFonts</code>: affects the <code>ghostscript</code> package. Ghostscript packages some URW fonts for the standard PostScript typefaces. If <code>true</code>, these fonts will be visible to GUI applications. You could set it to <code>true</code> if you want these fonts, but <code>gyre-fonts</code> (part of <code>fonts.enableDefaultPackages</code>) might be higher-quality depending on your judgement.
* <code>fonts.enableGhostscriptFonts</code>：影响 <code>ghostscript</code> 包。Ghostscript 为标准的 PostScript 字型打包了一些 URW 字体。若设为 <code>true</code>，这些字体将对 GUI 应用程序可见。如果您需要这些字体，可以设为 <code>true</code>，但 <code>gyre-fonts</code>（属于 <code>fonts.enableDefaultPackages</code> 的一部分）根据您的判断可能质量更高。


=== Using fonts from TexLive ===
=== 使用来自 TexLive 的字体 ===
You can make use of all TeX/LaTeX fonts from CTAN and [[TexLive]] by passing
您可以将 TexLive 包中的 `fonts` 属性传递给 `fonts.packages`，从而使用来自 CTAN 和 [[TexLive]] 的所有 TeX/LaTeX 字体：
the <code>fonts</code> attribute of your TexLive package to <code>fonts.package</code>:

=== Installing <code>nerdfonts</code> ===
=== 安装 <code> Nerd Fonts </code> ===


Individual Nerd Fonts can be installed like so:
单个Nerd Fonts可以像这样安装：


{{File|3=fonts.packages = with pkgs; [
{{File|3=fonts.packages = with pkgs; [
Line 61: Line 57:




 
可用的 Nerd Fonts 子包可以通过在 [[Searching packages|NixOS Package Search]] 中搜索 {{nixos:package|nerd-fonts.*}} 来列出，或者运行以下命令：<syntaxhighlight lang="console">
The available Nerd Font subpackages can be listed by searching for {{nixos:package|nerd-fonts.*}} on the [[Searching packages|NixOS Package Search]] or by running the following command: <syntaxhighlight lang="console">
$ nix-instantiate --eval --expr "with (import <nixpkgs> {}); lib.attrNames (lib.filterAttrs (_: lib.isDerivation) nerd-fonts)"
$ nix-instantiate --eval --expr "with (import <nixpkgs> {}); lib.attrNames (lib.filterAttrs (_: lib.isDerivation) nerd-fonts)"

==== Installing all <code>nerdfonts</code> ====
<span id="Installing_all_nerdfonts"></span>
==== 安装所有 <code>Nerd Fonts</code> ====


Installing all fonts from the [https://www.nerdfonts.com/ Nerd Fonts repository] is as simple as adding all of the individual packages to the NixOS configuration. The following line will do exactly that, by searching for all derivations under the <code>nerd-font</code> attribute:{{file|||<nowiki>
要安装来自 Nerd Fonts 仓库 的所有字体，只需将所有独立的包添加到 NixOS 配置中即可。以下代码行通过搜索 `nerd-fonts` 属性下的所有派生，精确实现这一目的：{{file|||<nowiki>
{  
{  
   fonts.packages = builtins.filter lib.attrsets.isDerivation (builtins.attrValues pkgs.nerd-fonts);
   fonts.packages = builtins.filter lib.attrsets.isDerivation (builtins.attrValues pkgs.nerd-fonts);
}
}

=== Patching nerdfonts into fonts ===
=== 将 nerdfonts 补丁应用到字体中 ===
Not all fonts have Nerd Fonts variants, thankfully you can easily patch them in yourself.
并非所有字体都有 Nerd Fonts 变体，但幸运的是，您可以轻松地自行打补丁。

}))|name=/etc/nixos/configuration.nix|lang=nix}}
}))|name=/etc/nixos/configuration.nix|lang=nix}}


=== Let Fontconfig know the fonts within your Nix profile ===
=== 让 Fontconfig 识别 Nix 配置文件中的字体 ===
Nix inserts its user profile path into <code>$XDG_DATA_DIRS</code>, which Fontconfig by default doesn't look in. This cause graphical applications like KDE Plasma not able to recognize the fonts installed via <code>nix-env</code> or <code>nix profile</code>.
Nix 会将其用户配置文件路径插入到 <code>$XDG_DATA_DIRS</code> 中，而 Fontconfig 默认并不在此路径中查找。这会导致 KDE Plasma 等图形应用程序无法识别通过 <code>nix-env</code> 或 <code>nix profile</code> 安装的字体。


To solve this, add the file <code>100-nix.conf</code> to your Fontconfig user configuration directory (usually <code>$XDG_CONFIG_HOME/fontconfig/conf.d</code>):
要解决此问题，请将 <code>100-nix.conf</code> 文件添加到 Fontconfig 用户配置目录中（通常为 <code>$XDG_CONFIG_HOME/fontconfig/conf.d</code>）：
<syntaxhighlight lang="xml">
<syntaxhighlight lang="xml">
<?xml version="1.0"?>

   <dir>NIX_PROFILE/share/fonts</dir>
</fontconfig>
</fontconfig>
</syntaxhighlight>
</syntaxhighlight>
and run <code>fc-cache</code>.
然后运行 <code>fc-cache</code>。


Alternatively, [https://nix-community.github.io/home-manager/options.xhtml#opt-fonts.fontconfig.enable enable Fontconfig configuration] in your Home Manager configuration.
或者，在您的 Home Manager 配置 <code>opt-fonts.fontconfig.enable</code> 中启用 Fontconfig 配置。

NixOS 的 [https://search.nixos.org/options?channel=unstable&from=0&size=50&sort=relevance&type=packages&query=fonts.fontconfig <code>fonts.fontconfig</code>] 配置项（点击查看完整列表！）用于处理 fontconfig 选项。部分选项已被 nix 很好地封装；此外始终可以使用 <code>localConf</code> 直接编写 XML 配置。


The nixos key [https://search.nixos.org/options?channel=unstable&from=0&size=50&sort=relevance&type=packages&query=fonts.fontconfig <code>fonts.fontconfig</code>] (click to see the full list!) handles the fontconfig options. Some options are nicely wrapped in nix; there's always <code>localConf</code> to go straight to the XML.

If you want to use other languages alongside English, you may want to set appropriate fonts for each language in your whole OS. For example, a Persian speaker might want to use the [https://rastikerdar.github.io/vazirmatn/ Vazirmatn] font for Persian texts, but [https://design.ubuntu.com/font/ Ubuntu] and Liberation Serif fonts for English texts. Just put these lines into your <code>configuration.nix</code>:

=== Use custom font substitutions ===
=== 使用自定义字体替换 ===


Sometimes, documents may appear to have bad kerning or hard-to-read letter spacing, due to a bad substitution.
有时，由于不恰当的替换，文档可能会出现字距不佳或字间距难以阅读的问题。
For example, Okular may show in the ''Document Properties'' dialog that it has substituted DejaVu Sans Mono (a sans-serif font) in place of "NewCenturySchlbk". <code>fc-match NewCenturySchlbk</code> would display similiar info.
例如，Okular 可能在“文档属性”对话框中显示已将 DejaVu Sans Mono（一种无衬线字体）替换为 "NewCenturySchlbk"。运行 <code>fc-match NewCenturySchlbk</code> 会显示类似信息。


Adding this to your <code>/etc/nixos/configuration.nix</code> should prompt it to use the more similar (and nicer) serif ''Schola'' font instead:
将此添加到您的 <code>/etc/nixos/configuration.nix</code> 中，应能促使其改用更相似（且更美观）的衬线字体 ''Schola'' 作为替代：
