问题描述
我已经使用 clojure 几个月了，我真的不明白为什么命名空间名称中的破折号必须在文件系统中表示为下划线.谁能向我解释一下，是否也可以在文件名中使用破折号?
I have been using clojure for a couple of months now and one thing I really don't understand is why dashes in namespace names must be represented as underscores in the filesystem. Can anyone explain this to me, and is it possible to be able to use dashes in the filenames too?
推荐答案
这是 Java 互操作性的必要解决方法.
It's a necessary workaround for Java interoperability.
当 Clojure 命名空间被 AOT(提前)编译成 Java .class 文件时，它的名称必须是有效的 Java 标识符.破折号在 Java 类名中无效，因此 Clojure 将它们转换为下划线.它还可以将 * 之类的字符转换为 _STAR_ 之类的词.
When a Clojure namespace is AOT (ahead-of-time) compiled into a Java .class file, it has to have a name that is a valid Java identifier. Dashes aren't valid in Java class names, so Clojure converts them to underscores. It also converts characters like * into words like _STAR_.
