用Haskell正则表达式库替换/替换 [英] replacement / substition with Haskell regex libraries

问题描述

在Haskell中是否存在用于使用正则表达式进行搜索和替换的高级API?特别是，我正在查看 Text.Regex.TDFA 或 Text.Regex.Posix 包.我真的很想要某种类型的东西:

Is there a high-level API for doing search-and-replace with regexes in Haskell? In particular, I'm looking at the Text.Regex.TDFA or Text.Regex.Posix packages. I'd really like something of type:

f :: Regex -> (ResultInfo -> m String) -> String -> m String

例如，用"cat"代替"dog"就可以写

so, for example, to replace "dog" with "cat" you could write

runIdentity . f "dog" (return . const "cat")    -- :: String -> String

或对单子进行更高级的操作，例如计算出现次数等.

or do more advanced things with the monad, like counting occurrences, etc.

非常缺少有关Haskell的文档.此处.

Haskell documentation for this is pretty lacking. Some low-level API notes are here.
