是翻译函数,它采用像enum或int这样的标准参数并提供本地化的颜色名称？

我有一个正在运行的部分,但只有两种语言(德语和英语)：

历史

首先是我之前的答案,它适用于将一个颜色标签设置为文件：https://stackoverflow.com/a/39751001/2227743.

然后@mz2发布了这个优秀的答案,成功地为文件设置了几个颜色标签并解释了这个过程：https://stackoverflow.com/a/40314367/2227743.

现在这个小插件,一个简单的follow-up到@ mz2的答案.

解

我只是简单地实现了@ mz2的建议：我已经使用获取Finder首选项的方法扩展了他的枚举示例,并在将属性设置到文件之前提取了正确的本地化标签颜色名称.

用法：
