Changelog for LeanCheck

v1.0.2 (January 2024)

  • improve error messages
  • some code linting, refactoring and cleanup
  • improve testing of LeanCheck itself

v1.0.0 (August 2022)

This release indicates that the Test.LeanCheck API is now stable. This is the same as v0.9.12 with just the version number change, the major bump here serves just to indicate stability. If your project works with the 0.9 series, it will work with the 1.0 series.

v0.9.12 (August 2022)

  • replace enumeration of Fractional and Floating types by the Calkin-Wilf sequence:
    • add listFloating and listFractional;
    • deprecate tiersFloating and tiersFractional;
  • improve the changelog with timestamps and history down to v0.5.0;
  • normalize code formatting throughout: indentation, spacing and width;
  • improve testing of LeanCheck itself;
  • test on GHC 9.2 and 9.4 (works with no changes).

v0.9.10 (June 2021)

  • Test.LeanCheck.Utils.Type: derive Typeable instances on GHC 7.8. Behaviour on newer GHCs (>= 7.10) versions is unaffected as they automatically derive Typeable instances for all types.

v0.9.8 (June 2021)

  • Test.LeanCheck.Utils.Type: Typeable instances on GHC 7.10. Behaviour on newer GHCs (>= 8.0) versions is unaffected as they automatically derive Typeable instances for all types. Update: these instances were already present on v0.9.6. LeanCheck v0.9.8 is essentially the same as v0.9.6.

v0.9.6 (May 2021)

  • no code changes in what is exported by Test.LeanCheck
  • Test.LeanCheck.Utils.Types: export the A, B, C, D, E and F types
  • slightly improve README
  • improve Makefile and tests
  • replace Travis by GitHub Actions as the CI system

v0.9.4 (April 2021)

  • no code changes in what is exported by Test.LeanCheck
  • add errorToLeft and anyErrorToLeft on Test.LeanCheck.Error
  • add ?==? and !==! on Test.LeanCheck.Error
  • add Test.LeanCheck.Function.List
  • add Test.LeanCheck.Function.Ord
  • reduce default argument enumeration to 12 on Test.LeanCheck.Function.Eq
  • add FAQ
  • improve Makefile and test scripts

v0.9.3 (March 2020)

  • improve Haddock documentation
  • use consistent code format
  • improve CI scripts and Makefile

v0.9.2 (March 2020)

  • rename most functions on Test.LeanCheck.Utils.Operators; deprecated names are provided;
  • improve documentation:
    • 100% haddock coverage;
    • LeanCheck memory usage thoroughly documented;
  • implement stub function conditionStatsT;
  • improve function display on Test.LeanCheck.Function.*;
  • fix some compiler warnings (newer GHC);
  • improve build scripts;
  • improve tests;
  • update tests scripts to support the new cabal (test/sdist).

v0.9.1 (February 2019)

  • fix bug in genericTiers where using it bound to a recursive datatype could cause an infinite loop;
  • minor improvements in documentation and tests.

v0.9.0 (January 2019)

  • logo for LeanCheck;
  • Listable instances to most types in the Haskell 2010 Language Report:
    • Word<n>;
    • Int<n>;
    • Complex;
    • etc...;
  • minor improvements in documentation and README.

v0.8.0 (November 2018)

  • export tiersFractional from Core and main module;
  • improve Listable instance for Floats and Doubles;
  • improve Show instance for functions;
  • improve Haddock documentation;
  • remove experimental function enumeration modules, in favour of the working ListsOfPairs enumeration;
  • add special String and Char types to Utils.Types;
  • fix bug in the Natural type of the Utils.Types modules;
  • force non-negativity in Natural and Nat types from Utils.Types;
  • rename some exported symbols in the ShowFunction module;
  • improve tests of LeanCheck itself.

v0.7.7 (October 2018)

  • Add a changelog.md file with the contents of git tag annotations: git tag -ln99.

v0.7.6 (October 2018)

  • Add experimental Test.LeanCheck.Generic module with automatic derivation of Listable instances through GHC.Generics;
  • Improve Haddock documentation.

v0.7.5 (September 2018)

  • Fix tests on systems with case-insensitive filesystems, like:
    • Windows;
    • Mac OS;
  • Fix tests on GHC 8.6.

This release fixes just the tests of LeanCheck itself. The LeanCheck library is otherwise unaffected.

v0.7.4 (September 2018)

  • Add list of providers on README;
  • Minor fix in haddock.

v0.7.3 (August 2018)

  • Fix bug: add missing Hugs backport file to source distribution (GHC users were not affected by this);
  • Improve tests so I don't forget to include files in the source distribution (cabal sdist) again.

v0.7.2 (August 2018)

  • Significantly improve documentation;
  • Slightly improve tests.

v0.7.1 (July 2018)

  • LeanCheck now works on Hugs-200607 (only minor changes were needed);
  • Implement functions that calculate statistics: Test.LeanCheck.Stats;
  • More stuff on Utils: rational, okNum;
  • Improve tests;
  • Improve build scripts;
  • Minor assorted fixes.

v0.7.0 (December 2017)

  • Improved cabal file;
  • Cabal package now has all files checked in on git repo;
  • Add functions to compute Listable statistics (and some stubs);
  • Improve tests;
  • Code improvements (refactoring).

v0.6.7 (September 2017)

The only change in relation to v0.6.6 is a fixed build on Travis (the reference output files were outdated). The code of the tool is otherwise unchanged.

v0.6.6 (September 2017)

  • Improve showing of functional counter-examples.

v0.6.5 (August 2017)

  • Export ordering from 'Test.LeanCheck.TypeBinding';
  • Improve documentation;

v0.6.3 (July 2017)

  • Test.LeanCheck: Add the delay and reset functions;
  • Test.LeanCheck.Tiers: normalizeT stripping up to 12 empty tiers;
  • Some refactoring;
  • Add lots of new tests for LeanCheck itself.
