+title: 富文本语法
+---
+
+## 对于普通用户
+
+Tailchat 内置了 `com.msgbyte.bbcode` 插件用于对富文本消息做支持(且是默认安装的)。
+
+以下是目前 `bbcode` 插件支持的语法列表：
+
+| 关键字 | 描述 | 用法示例 | 预览 |
+| ------ | ----- | ------ | ----- |
+| b | 文本加粗 | `[b]foo[/b]` | <b>foo</b> |
+| i | 文本倾斜 | `[i]foo[/i]` | <i>foo</i> |
+| u | 文本下划线 | `[u]foo[/u]` | <ins>foo</ins> |
+| s | 文本删除线 | `[s]foo[/s]` | <del>foo</del> |
+| url | 超链接 | <div style={{width: 400}}>`[url]https://tailchat.msgbyte.com[/url]` / `[url=https://tailchat.msgbyte.com]官网[/url]`</div> | <a>https://tailchat.msgbyte.com</a> / <a href="https://tailchat.msgbyte.com">官网</a> |
+| img | 图片 | `[img]https://tailchat.msgbyte.com/img/logo.svg[/img]` | <div style={{width: 60}}><img src="https://tailchat.msgbyte.com/img/logo.svg" /></div>  |
+| at | 提及 | `[at=<hereisuserid>]moonrailgun[/at]` | - |
+| emoji | 表情 | `[emoji]smile[/emoji]` | - |
+| markdown / md | markdown语法支持 | `[markdown]## Heading[/markdown]` | - |
+
+## 对于插件开发者
+
+如果你的插件需要使用统一的富文本支持，请在你的渲染函数中这样实现:
+
+```jsx
+import { getMessageRender } from '@capital/common';
+
+const Component = (text: string) => {
+  return <div>{getMessageRender(text)}</div>
+}
+```
