如何将该Java正则表达式转换为Go的正则表达式语法？

Question

I'm trying to convert this Java regular expression to Go's regular expression syntax:

[:]?([\D&&[^/]]./)?(/|[\D&&[^/]][^/])

This regular expression is the regex for matching Clojure keywords, taken from the JVM Clojure compiler.

Answer 1

It should be

var pattern = regexp.MustCompile(`:?([^/\d].*/)?(/|[^\d/][^/]*)`) 

The pattern [\D&&[^/]] means any non-digit but a /, and it can be expressed with an extended negated character class [^\d/].
