elixir - 如何在 elixir 中拆分字符串以保持分隔符？

Question

我有一个带有特殊字符的字符串:

>> text = "ab()-cdef"

我想将列表中的字母与特殊字符分开

>> list = ["ab", "(" , ")" ,"-", "cdef"]

我试过

list = String.split(text,["(",")","-"], trim: false)

但是我丢失了特殊字符

list = ["ab","","","","cdef"]

documentation for Regex.split提到 :include_captures 选项:

iex> Regex.split(~r{(x)}, "Elixir", include_captures: true)
["Eli", "x", "ir"]

iex> Regex.split(~r{a(?<second>b)c}, "abc", on: [:second], include_captures: true)
["a", "b", "c"]

注意当String.split与正则表达式一起使用，您也可以使用此选项。
