replacement / substition with Haskell regex libraries

Question

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

Answer 1

How about the Text.Regex.subRegex in package regex-compat?

Prelude> import Text.Regex (mkRegex, subRegex)

Prelude> :t mkRegex
mkRegex :: String -> Regex

Prelude> :t subRegex
subRegex :: Regex -> String -> String -> String

Prelude> subRegex (mkRegex "foo") "foobar" "123"
"123bar"
