lens-family-core: Haskell 2022 Lens Families

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

This package provides first class(†) functional references in Van Laarhoven style supporting the following optics:

  • Lenses (view, over)

  • Traversals (toListOf, matching, over)

  • Setters (over)

  • Grates (zipWithOf, under, review)

  • Resetters (under)

  • Adapters (view, review)

  • Grids (toListOf, over / under, review)

  • Prisms (matching, over / under, review)

  • Getters (view)

  • Folders (toListOf)

  • Reviewers (review)

(†) 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 and traversals for those who cannot support rank 2 polymorphism.
