This package provides extra definitions and instances that extend the optics-core package, without incurring too many dependencies. See the optics package for more documentation.

Changes

optics-extra-0.4.2.1 (2022-05-20)

  • Fix for previous release when used with mtl-2.3 and transformers-0.5.

optics-extra-0.4.2 (2022-05-19)

  • Allow transformers-0.6 and mtl-2.3

    Note that optics-extra no longer defines Zoom instances for ErrorT or ListT when building with mtl-2.3 or later. This is because MonadState is a superclass of Zoom, and the MonadState instances for ErrorT and ListT were removed in mtl-2.3. Be watchful of this if you build optics-extra with mtl-2.3 (or later) combined with an older version of transformers (pre-0.6) that defines ErrorT or ListT. Similarly for Magnify and MagnifyMany.

optics-extra-0.4.1 (2022-03-22)

  • Add support for GHC-9.2

optics-extra-0.4 (2021-02-22)

  • Add support for GHC-9.0

optics-extra-0.3 (2020-04-15)

  • optics-core-0.3 compatible release
  • GHC-8.10 support
  • Use stricter uncurry' for better performance

optics-extra-0.2 (2019-10-18)

  • optics-core-0.2 compatible release
  • Move use from Optics.View to Optics.State and restrict its type
  • Add preuse to Optics.State
  • Rename use, uses, listening and listenings to reflect the fact that they have ViewResult-generalised types
  • Depend on new indexed-profunctors package

optics-extra-0.1 (2019-09-02)

  • Initial release
