Haskell Lens Type at Jim Dubois blog

Haskell Lens Type. This package provides families of lenses, isomorphisms, folds, traversals, getters and setters. Within an outer value of type s; The tools are lenses and prisms. You can let the library automatically derive lenses for fields of your data type. If you are looking for where to get started, a crash course video on how lens was constructed and. Lenses provide language support for viewing and editing structures in a way that ensures your edits are consistent; Lenses and prisms offer a different way to have getters and setters to our objects. Provide (a) new inner value (s) of type b. Focus on an inner value of type a. By the end of this tutorial you should: What is provided in this library is a number of stock lenses and traversals for common haskell types, a wide array of combinators for working them, and more exotic functionality, (e.g. Understand what problems the lens library solves, know when it is appropriate to use the lens library, be proficient. This module exports the majority of the types that need to appear in user signatures or in.
