使用 fontspec 来配置可变字体，可能会让文档的导言区堆满大量设置代码。在这一步中，我们展示如何创建一个简单的包来容纳 fontspec 的配置代码——从而简化文档导言区，并使后续更改字体更加容易。

## 如何创建并使用一个简单的 LaTeX 宏包

按照以下步骤，为我们在本教程中创建的 fontspec 配置代码制作一个简单的 LaTeX 宏包。

1. 选择 **新建文件** 图标（![Overleaf icon representing adding a file](/files/5623f943b055888fb427a88ae16784acad4dea0b)）以创建一个新的项目文件。将其命名为 `myfontsettings.sty` 并选择 **创建**.

3. 将 fontspec 配置代码粘贴到文件 `myfontsettings.sty`中。这里，我们使用的是在可变字体教程中添加的 Noto Serif、Noto Sans 和 Roboto Mono 的 fontspec 配置代码。如果你使用不同的可变字体，就必须修改 fontspec 设置。

```latex
% myfontsettings.sty
\NeedsTeXFormat{LaTeX2e}
\ProvidesPackage{myfontsettings}[2024/06/13 v1.0 My custom font settings]

% This simple package contains your fontspec configuration
% It keeps your document's preamble clean and tidy

% Load fontspec package
\RequirePackage{fontspec}

% Set the main text font for the document
\setmainfont{NotoSerif-VariableFont-wdth-wght.ttf}[
Weight=400,
ItalicFont=NotoSerif-Italic-VariableFont-wdth-wght.ttf,
FontFace = {b}{n}{Font =NotoSerif-VariableFont-wdth-wght.ttf,Weight=600},
FontFace = {b}{it}{Font =NotoSerif-Italic-VariableFont-wdth-wght.ttf,Weight=600}
]

% Document family sans serif font
\setsansfont{NotoSans-VariableFont-wdth-wght.ttf}[
Weight=400,
ItalicFont=NotoSans-Italic-VariableFont-wdth-wght.ttf,
FontFace = {b}{n}{Font = NotoSans-VariableFont-wdth-wght.ttf,Weight=600},
FontFace = {b}{it}{Font = NotoSans-Italic-VariableFont-wdth-wght.ttf,Weight=600}
]

% Document family monospaced font
\setmonofont{RobotoMono-VariableFont-wght.ttf}[
NFSSFamily=RobotoMono,
Weight=300,
ItalicFont=RobotoMono-Italic-VariableFont-wght.ttf,
FontFace = {b}{n}{Font =RobotoMono-VariableFont-wght.ttf,Weight=550},
FontFace = {b}{it}{Font = RobotoMono-Italic-VariableFont-wght.ttf, Weight=550}
]

\endinput
```

5. 要使用此宏包，请将以下行添加到 `\usepackage{myfontsetting}` 你的文档导言区中。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://ayakaleaf-pro.ayaka.space/latex/zh-cn/shen-du-wen-zhang/44-step-8-how-to-create-a-simple-latex-package-to-configure-your-variable-fonts.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
