profunctor-optics: A compact optics library compatible with the typeclasses in profunctors.

[ bsd3, data, lenses, library, profunctors, program ] [ Propose Tags ] [ Report a vulnerability ]

This package provides utilities for creating and manipulating profunctor-based optics. Some highlights:

Full complement of isos, prisms, lenses, grates, traversals, cotraversals, views, setters, folds, and more.

Compact & straight-forward implementation.

Fully interoperable. All that is required to create optics is the profunctors package. Optics compose with (.) from Prelude as is typical. Conversions to & from the Van Laarhoven representations are provided for each optic type.

Well-documented properties and exportable predicates for testing your own optics.

See the Readme file for more information.
