Haskell pattern matching char in a string

Question

I have a question on pattern matching:

Is it possible to somehow match a (string ++ [char] ++ anotherstring)?

I have tried something like:

f          


        

Answer 1

For completeness' sake, one could make gratuitous use of GHC's ViewPatterns extension, and rewrite Daniel Fischer's example as something like:

{-# LANGUAGE ViewPatterns #-}

f (break (== ';') -> (s, _:r)) = s ++ r
f _ = error "No semicolon found"

This is of course a purely cosmetic change, but if you prefer the usual "group of equations" syntax instead of case expressions, there it is.

N.B. -- I don't have GHC at hand right now so I haven't actually tested the above.
