• 4.2.0.1

  • Missed removing Semigroup constraint from chooseWith

• 4.2.0.0

  • Replaced also and alternatively with chooseWith

• 4.1.0.0

• 4.0.0.0

  • Renamed itemXXX to pieceXXX, Itemized to Pieced, itemizedXXX to piecedXXX.

• 3.1.1.0

  • itemTag only requires Has and likewise facetTag only requires AsFacet.

• 3.1.0.0

  • Replaced HasItem with Data.Has.

• 3.0.0.2

  • Fixed haddock.

• 3.0.0.1

• 3.0.0.0

  • Renamed SelectWith to MakeFrom, split ChooseBtween to ChooseBoth and ChooseFrom.
  • Removed hard to remember operators `>&&> *&&* +||+ >||>
  • Removed faceted'
  • Added instance AsFacet Void (Which '[]) and instance AsFacet (Which '[]) Void
  • Polymorphic HasItemX now only requires two to three type args.

• 2.1.0.0

  • Removed profunctor variable w from the constraint synonyms for Projected/Injected.

• 2.0.0.1

  • Forgot to expose constraint synonyms for Projected/Injected.

• 2.0.0.0

  • Breaking change: Removed HasProject and AsInject typeclasses and changed them back to functions.
  • Added MatchingFacet typeclasses for polymorphic matching of prisms.
  • Added constraint synonyms for Project/Inject/Projected/Injected.

• 1.0.0.1

  • Fixed missing exports of the new lens classes.

• 1.0.0.0

  • Removed overlapping instances of Data.Generics lens
  • Using typeclass instead of plain functions so that lens can be used for other data types
  • Added default implementations for some of these typeclasses using Data.Generic typeclasses.
  • Breaking change: the xxx' version of functions are now consistently the simpler or non-polymorphic version - This is more consistent with 'Control.Lens' as well.
  • This means the following are swapped:
    • item, item'
    • itemL, itemL'
    • itemTag, itemTag'
    • itemN, itemN'
    • project, project'
    • projectL, projectL'
    • projectN, projectN'

  • Added itemTag and facetTag that also tag/untags the field.
  • Added overlapping instances of Data.Generics lens

• 0.5.1.0

  • Added faceted, injected, itemized, projected, which is analogous to Profunctor Choice and Strong but using Which and Many
  • Added +||+ (analogous to +++ and |||), >||>; and *&&* (analogous to *** and &&&), and >&&>.

• 0.5.0.0

  • min bounds: data-diverse >=1.2.1
  • Rerranged type variable for xxxL and xxxN functions so that the @[email protected] inferrred from label @[email protected] or index @[email protected] is after @[email protected].
  • This affects item[L|N], item[L|N]', replace[L|N]', facet[L|N]
  • Same change was made in data-diverse-1.2.0.0

• 0.4.0.1

  • included data-diverse 1.0 in the upper bounds

• 0.4.0.0

  • Changed type variable ordering of itemL and itemL, so it's consistently x, y, then xs

• 0.3.0.0

  • Changed type variable ordering of facetL and facetN, so it's consistently x then xs

• pre 0.3.0.0

  • Initial version.
