如何在Haskell中分割字符串？ [英] How to split a string in Haskell?

问题描述

行和 words 在分隔空格或换行符时很好用，但当然有一种标准的方式来分隔逗号？我无法在Hoogle上找到它？

具体而言，我正在寻找 split，my，comma，分隔列表返回 [my，comma，separated，list]

感谢。

解决方案

有一个名为 split 。

  cabal install split 
  

像这样使用它：

  ghci> import Data.List.Split 
 ghci> splitOn，，逗号，分隔，列表
 [my，逗号，分隔，列表] 
  

它具有许多其他功能，用于分割匹配分隔符或者具有多个分隔符。

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

lines and words work great from spliting on a space or newline, but surely there is a standard way to split on a comma? I couldn't fint it at Hoogle?

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

Thanks.

解决方案

There is a package for this called split.

cabal install split

Use it like this:

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

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