Hugo 使用 [Chroma](https://github.com/alecthomas/chroma)，一种纯 Golang 实现的代码高亮渲染器.
|
|
建议对 Markdown 内容中的代码块使用反引号. 例如:
|
|
|
|
<!--more-->
|
|
|
|
````markdown {filename="Markdown"}
|
|
```python
|
|
def say_hello():
|
|
print("Hello!")
|
|
```
|
|
````
|
|
|
|
将呈现为：
|
|
|
|
```python
|
|
def say_hello():
|
|
print("Hello!")
|
|
```
|
|
|
|
## 特性
|
|
|
|
### 文件名
|
|
|
|
要向代码块添加文件名或标题, 请设置 `filename`:
|
|
|
|
````markdown {filename="Markdown"}
|
|
```python {filename="hello.py"}
|
|
def say_hello():
|
|
print("Hello!")
|
|
```
|
|
````
|
|
|
|
```python {filename="hello.py"}
|
|
def say_hello():
|
|
print("Hello!")
|
|
```
|
|
|
|
### 行号
|
|
|
|
如需设置行号, 将 `linenos` 设置为 `table` , 并将 `linenostart` 设置为起始行号:
|
|
|
|
````markdown {filename="Markdown"}
|
|
```python {linenos=table,linenostart=42}
|
|
def say_hello():
|
|
print("Hello!")
|
|
```
|
|
````
|
|
|
|
```python {linenos=table,linenostart=42}
|
|
def say_hello():
|
|
print("Hello!")
|
|
```
|
|
|
|
### 突出显示线条
|
|
|
|
要突出显示线条, 设置 `hl_lines` 为行号:
|
|
|
|
````markdown {filename="Markdown"}
|
|
```python {linenos=table,hl_lines=[2,4],linenostart=1,filename="hello.py"}
|
|
def say_hello():
|
|
print("Hello!")
|
|
|
|
def main():
|
|
say_hello()
|
|
```
|
|
````
|
|
|
|
```python {linenos=table,hl_lines=[2,4],linenostart=1,filename="hello.py"}
|
|
def say_hello():
|
|
print("Hello!")
|
|
|
|
def main():
|
|
say_hello()
|
|
```
|
|
|
|
|
|
### 复制按钮
|
|
|
|
默认情况下, 为代码块启用复制按钮.
