正则表达式分为单词和标点符号

Question

I have the following input:

func add(var a:Int, var b:Int) -> Int
{
    return a + b
}

I'm using this Regex \\s*\\b\\s* which I found online which is supposed to split up words and punctuation/symbols. I tried it and it split up the input to

func
add
(
var
...

Which is working exactly how I want it to, until it finds the -> sign, where it outputs

:
Int
) ->
...

Everything else works fine but I would like it to output

)
-
>

instead.

How can I achieve this? Thank you in advance.

由于我不完全知道您正在使用哪个版本的regexp以及正在运行的命令来对其进行验证，因此我无法完全确定这是否可以解决您的问题，但是应该。

\s*(\b|[->])\s*
