Re: [Haskell-cafe] diff implementation in haskell

asviraspossible:

Are there pure haskell implementations of diff and diff3 algorithms. Like:

...

data Diff a = Deleted [a] | Common [a] | Added [a]

diff :: Eq a => [a] -> [a] -> [Diff a]

diff3 :: Eq a => [a] -> [a] -> [a] -> [a]

There's at least one on Hackage: http://hackage.haskell.org/package/Diff -- Donn
