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.
