  * - showBackground: 控制是否显示代码块的背景色区分
  * - enableAutoDetection: 控制是否启用内容的语言自动检测功能
  * - defaultLanguage: 新建代码块时使用的默认语言（也是自动检测的回退语言）
  * - defaultAutoDetect: 新建代码块时是否默认添加-a标记启用自动检测

  * 注意：defaultLanguage 和 defaultAutoDetect 是配合使用的：
  * - 如果 defaultAutoDetect=true，新建块会是 ∞∞∞javascript-a（会根据内容自动检测语言）
  * - 如果 defaultAutoDetect=false，新建块会是 ∞∞∞javascript（固定使用指定语言）
