|

|
|
## 基础语法
|
|
|
|
|
|
|
|
|
|
|
|
Halo 使用的 `Markdown` 解析器为 [flexmark-java](https://github.com/vsch/flexmark-java)，基于 [CommonMark (spec 0.28)](https://spec.commonmark.org/0.28/) 标准开发，语法参考：[https://spec.commonmark.org/0.28/](https://spec.commonmark.org/0.28/)。
|
|
|
|
|
|
|
|
|
|
|
|
## 代码块
|
|
|
|
|
|
|
|
|
|
|
|
````markdown
|
|
|
|
|
|
```language
|
|
|
|
|
|
代码块
|
|
|
|
|
|
```
|
|
|
|
|
|
````
|
|
|
|
|
|
|
|
|
|
|
|
其中，language 为必填，如果不填写，很可能主题的代码高亮插件无法识别代码的语言，导致样式异常。举几个例子：
|
|
|
|
|
|
|
|
|
|
|
|
````markdown
|
|
|
|
|
|
```java
|
|
|
|
|
|
public static void main(String[] args){
|
|
|
|
|
|
System.out.println("Hello World!");
|
|
|
|
|
|
}
|
|
|
|
|
|
```
|
|
|
|
|
|
````
|
|
|
|
|
|
|
|
|
|
|
|
````markdown
|
|
|
|
|
|
```javascript
|
|
|
|
|
|
console.log("Hello World!")
|
|
|
|
|
|
```
|
|
|
|
|
|
````
|
|
|
|
|
|
|
|
|
|
|
|
## TOC
|
|
|
|
|
|
|
|
|
|
|
|
在文章的最前面加上 `[TOC]` 即可。
|
|
|
|
|
|
|
|
|
|
|
|
## 自动链接
|
|
|
|
|
|
|
|
|
|
|
|
支持自动将一个链接解析为可点击的格式，如下：
|
|
|
|
|
|
|
|
|
|
|
|
```markdown
|
|
|
|
|
|
https://halo.run
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
将被解析为：
|
|
|
|
|
|
|
|
|
|
|
|
```html
|
|
|
|
|
|
<a href="https://halo.run">https://halo.run</a>
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
## Emoji
|
|
|
|
|
|
|
|
|
|
|
|
支持将 Emoji 的文字形式转化为图片形式，如下：
|
|
|
|
|
|
|
|
|
|
|
|
```markdown
|
|
|
|
|
|
:100:
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
将被解析为：
|
|
|
|
|
|
|
|
|
|
|
|
```html
|
|
|
|
|
|
💯
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|

## 数学公式
|
|
|
|
|
|
|
|
|
|
|
|
行内公式：
|
|
|
|
|
|
|
|
|
|
|
|
```markdown
|
|
|
|
|
|
$a \ne 0$
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
段落公式：
|
|
|
|
|
|
|
|
|
|
|
|
```markdown
|
|
|
|
|
|
$$
|
|
|
|
|
|
x = {-b \pm \sqrt{b^2-4ac} \over 2a}.
|
|
|
|
|
|
$$
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
> 需要注意的是，并不是每一款主题都支持显示数学公式，你可以先到你使用的主题设置中查看是否支持，如不支持，请看下面的解决方案。

Halo 内置一些短连接以更好地支持一些 HTML 语法，但是编辑器目前并不能解析，只能发布之后才可以看到效果，如下：
