如何在 Haskell 中拆分字符串? [英] How to split a string in Haskell?

问题描述

在 Haskell 中是否有标准的方法来拆分字符串?

Is there a standard way to split a string in Haskell?

lines 和 words 在空格或换行符上分割效果很好，但肯定有一种标准的方法来分割逗号吗?

lines and words work great from splitting on a space or newline, but surely there is a standard way to split on a comma?

我在 Hoogle 上找不到.

I couldn't find it on Hoogle.

具体来说，我正在寻找 split "," "my,comma,separated,list" 返回 ["my","comma","separated" 的内容,"list"].

To be specific, I'm looking for something where split "," "my,comma,separated,list" returns ["my","comma","separated","list"].

推荐答案

有一个名为 拆分.

cabal install split

像这样使用它:

ghci> import Data.List.Split
ghci> splitOn "," "my,comma,separated,list"
["my","comma","separated","list"]

它带有许多其他功能，用于分割匹配的分隔符或具有多个分隔符.

It comes with a lot of other functions for splitting on matching delimiters or having several delimiters.
