Changelog

Latest version: https://github.com/Lysxia/generic-random/blob/master/changelog.md

1.5.0.1

  • Support GHC 9.2

1.5.0.0

  • Add newtypes for DerivingVia (thanks, blackheaven)
  • Drop compatibility with GHC 8.0 and 8.2

1.4.0.0

  • Add option to use only coherent instances
  • Export SetSized and SetUnsized
  • Drop compatibility with GHC 7

1.3.0.1

  • Fix small typos in documentation.

1.3.0.0

  • Add ConstrGen (custom generators for fields specified by constructor name and index).
  • Stop requiring custom generators lists to be terminated by :+ (), or to be lists at all.
  • Breaking minor change: when a record field has a different type than a FieldGen custom generator for the same field name, this is now a compilation error. This was simply ignored before.
  • Miscellaneous documentation improvements in Generic.Random module.

1.2.0.0

  • Fix a bug where generators did not decrease the size parameter with single-field constructors

  • The sized generators now use a custom generator for lists. Use genericArbitraryRecG () to disable that. See tutorial for more information.

  • Lists of custom generators are now constructed using (:+) instead of GenList

  • Rename Field to FieldGen

  • Add Gen1, Gen1_ (custom generators for unary type constructors)

  • Add listOf', listOf1', vectorOf'

  • Remove deprecated module Generic.Random.Generic

1.1.0.2

  • Improved performance

1.1.0.1

  • Fix build for GHC<8

1.1.0.0

  • Add option to specify custom generators for certain fields, overriding Arbitrary instances
    • Add genericArbitraryG, genericArbitraryUG, genericArbitrarySingleG, genericArbitraryRecG
  • Add GArbitrary and GUniformWeight synonyms
  • Deprecate Generic.Random.Generic
  • Remove weights from the external API

1.0.0.0

  • Make the main module Generic.Random
  • Rework generic base case generation
    • You can explicitly provide a trivial generator (e.g., returning a nullary constructor) using withBaseCase
    • Generically derive BaseCaseSearch and let BaseCase find small values, no depth parameter must be specified anymore
  • Add genericArbitrarySingle, genericArbitraryRec, genericArbitraryU'
  • Deprecate weights
  • Fixed bug with genericArbitrary' not dividing the size parameter

0.5.0.0

  • Turn off dependency on boltzmann-samplers by default
  • Add genericArbitraryU, genericArbitraryU0 and genericArbitraryU1
  • Compatible with GHC 7.8.4 and GHC 7.10.3

0.4.1.0

  • Move Boltzmann sampler modules to another package: boltzmann-samplers

0.4.0.0

  • Check well-formedness of constructor distributions at compile time.
  • No longer support GHC 7.10.3 (the above feature relies on Generic information which does not exist before GHC 8)

0.3.0.0

  • Support GHC 7.10.3
  • Replace TypeApplications with ad-hoc data types in genericArbitraryFrequency'/genericArbitrary'
