代码块

目录

Rouge 提供了许多不同的代码块“提示”。如果你省略提示，它会尝试猜测，有时会猜错。这些只是我们经常使用的一些提示。

变量

如果你的示例包含一个可能更改的占位符值，请对占位符值使用格式 <[A-Z_]+>：<MY_VARIABLE>

export name=<MY_NAME>

此语法保留用于变量名，并将使变量以特殊的颜色和字体样式渲染。

高亮行

incoming := map[string]interface{}{
    "asdf": 1,
    "qwer": []interface{}{},
    "zxcv": []interface{}{
        map[string]interface{}{},
        true,
        int(1e9),
        "tyui",
    },
}    
```go {hl_lines=[7,8]}
incoming := map[string]interface{}{
    "asdf": 1,
    "qwer": []interface{}{},
    "zxcv": []interface{}{
        map[string]interface{}{},
        true,
        int(1e9),
        "tyui",
    },
}

Bash

当你想显示 Bash 脚本时，使用 bash 语言的代码块。

#!/usr/bin/bash
echo "deb https://packages.docker.com/1.12/apt/repo ubuntu-trusty main" | sudo tee /etc/apt/sources.list.d/docker.list

如果你想显示交互式 Shell，请改用 console。在使用 console 的情况下，请确保为用户符号添加一个美元字符。

$ echo "deb https://packages.docker.com/1.12/apt/repo ubuntu-trusty main" | sudo tee /etc/apt/sources.list.d/docker.list

Go

incoming := map[string]interface{}{
    "asdf": 1,
    "qwer": []interface{}{},
    "zxcv": []interface{}{
        map[string]interface{}{},
        true,
        int(1e9),
        "tyui",
    },
}
