Types

6 declarations
datadata Expr
#

A untyped Haskell-like expression.

Having richer structure than just Tree allows to have richer diffs.

datadata Edit a

List edit operations

The Swp constructor is redundant, but it let us spot a recursion point when performing tree diffs.

Constructors

  • Ins a

    insert

  • Del a

    delete

  • Cpy a

    copy unchanged

  • Swp a a

    swap, i.e. delete + insert
