lens-family-core: Haskell 98 Lens Families

[ bsd3, data, lenses, library ] [ Propose Tags ]

This package provides first class(†) functional references. In addition to the usual operations of getting, setting and composition, plus integration with the state monad, lens families provide some unique features:

  • Polymorphic updating

  • Cast projection functions to read-only lenses

  • Cast semantic editor combinators to modify-only lenses

(†) For optimal first-class support use the lens-family package with rank 2 / rank N polymorphism. Lens.Family.Clone allows for first-class support of lenses for those who require Haskell 98.
