# 你们支持哪些宏包？

我们使用 [TeX Live](http://www.tug.org/texlive/) 2024 适用于新项目和现有项目的副本，提供约 4000 个宏包，包括：

* 使用……的图形 [pstricks](https://en.wikipedia.org/wiki/PSTricks) 和 [TikZ](http://en.wikipedia.org/wiki/PGF/TikZ)。以下是 [一些示例](https://www.overleaf.com/latex/examples/tagged/tikz).
* 带有……的参考文献 [bibtex](http://www.bibtex.org/) 和 [biblatex](http://www.ctan.org/pkg/biblatex)。以下是 [一些示例](https://www.overleaf.com/gallery/tagged/bibliography).
* 宏包，例如 `fontspec` 需要 XeLaTeX 或 LuaLaTeX 提供 Unicode 和字体支持。

更多详情请参见 [这篇博文](https://www.overleaf.com/blog/tex-live-2024-is-now-available).

现有项目将继续使用项目创建时当时的 TeX Live 镜像——这可以防止未来宏包更新可能引入的不利影响，例如不兼容性。

若要更新现有项目所使用的 TeX Live 版本，您可以 [复制该项目](/latex/zh-cn/zhi-shi-ku/030-copying-a-project.md) 这会自动将复制后的项目更新为使用 Overleaf 最新版本的 TeX Live。或者，也可以手动将克隆（复制）后的项目配置为 [使用不同版本的 TeX Live](https://www.overleaf.com/blog/new-feature-select-your-tex-live-compiler-version).

另外请注意，您可以上传 `.sty` 和 `.cls` 其他宏包的文件，例如来自 [CTAN](http://ctan.org).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/zhi-shi-ku/155-what-packages-do-you-support.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.
