synopsis:            Diffing of (expression) trees.
category:            Data, Testing
description:
  Common diff algorithm works on list structures:
  .
  @
  diff :: Eq a => [a] -> [a] -> [Edit a]
  @
  .
  This package works on trees.
  .
  @
  treeDiff :: Eq a => Tree a -> Tree a -> Edit (EditTree a)
  @
  .
  This package also provides a way to diff arbitrary ADTs,
  using @Generics@-derivable helpers.
  .
  This package differs from <http://hackage.haskell.org/package/gdiff gdiff>,
  in a two ways: @tree-diff@ doesn't have patch function,
  and the "edit-script" is a tree itself, which is useful for pretty-printing.
  .
  @
  >>> prettyEditExpr $ ediff (Foo 42 [True, False] "old") (Foo 42 [False, False, True] "new")
  Foo
    {fooBool = [-True, +False, False, +True],
     fooInt = 42,
     fooString = -"old" +"new"}
