英文:
Convert regex from Java to Go
问题
我使用reregexp2库。
这个正则表达式在Go中不起作用，会报错：
regexp2: Compile((?<=^|[a-z]\-|[\s\p{Punct}&&[^\-]])([A-Z][A-Z0-9_]*-\d+)(?![^\W_])): error parsing regexp: unknown unicode category, script, or property 'Punct' in (?<=^|[a-z]\-|[\s\p{Punct}&&[^\-]])([A-Z][A-Z0-9_]*-\d+)(?![^\W_])
我希望它能正常执行。
英文:
(?<=^|[a-z]\-|[\s\p{Punct}&&[^\-]])([A-Z][A-Z0-9_]*-\d+)(?![^\W_])
I use the library reregexp2
This RE does not work in Go and will report error:
regexp2: Compile(`(?<=^|[a-z]\-|[\s\p{Punct}&&[^\-]])([A-Z][A-Z0-9_]*-\d+)(?![^\W_])`): error parsing regexp: unknown unicode category, script, or property 'Punct' in `(?<=^|[a-z]\-|[\s\p{Punct}&&[^\-]])([A-Z][A-Z0-9_]*-\d+)(?![^\W_])`
I hope it can be executed normally

如果你查看Java regex Pattern documentation，你会发现\p{Punct}表示的是标点符号：其中包括!"#$%&'()*+,-./:;<=>?@[]^_{|}~。
所以，如果你想将其转换为Go语言的正则表达式，请参考regexp syntax documentation。
英文:
If you take a look at Java regex Pattern documentation, you'll see that \p{Punct} is Punctuation: One of !"#$%&'()*+,-./:;<=>?@[\]^_{|}~
>\p{Punct} Punctuation: One of !"#$%&'()*+,-./:;<=>?@[]^_`{|}~
So what you need to convert this to a go regex checking the regexp syntax documentation
