Changelog

v0.5.3 (2021-10-14)

• Minor performance optimization in pick.

v0.5.2 (2020-12-24)

• Fix regression in v0.5.1 that broke get/has for dictionaries and dot-delimited keys that reference integer dict-keys.

v0.5.1 (2020-12-14)

• Fix bug in get/has that caused defaultdict objects to get populated on key access.

v0.5.0 (2020-10-23)

• Fix bug in intersection/intersectionby and difference/differenceby where incorrect results could be returned when generators passed in as the sequences to compare with.
• Add support for Python 3.9.
• Drop support for Python <= 3.5.

v0.4.0 (2019-01-23)

• Add functions:
  • differenceby
  • duplicatesby
  • intersectionby
  • unionby

v0.3.0 (2018-08-31)

• compose: Introduce new “partial” shorthand where instead of passing a callable, a tuple can be given which will then be converted to a callable using functools.partial. For example, instead of fnc.compose(partial(fnc.filter, {'active': True}), partial(fnc.map, 'email')), one can do fnc.compose((fnc.filter, {'active': True}), (fnc.map, 'email')).

v0.2.0 (2018-08-24)

• Add functions:
  • negate
  • over
  • overall
  • overany
• Rename functions: (breaking change)
  • ismatch -> conforms
  • matches -> conformance
• Make conforms/conformance (formerly ismatch/matches) accept callable dictionary values that act as predicates against comparison target. (breaking change)

v0.1.1 (2018-08-17)

• pick: Don’t return None for keys that don’t exist in source object. Instead of fnc.pick(['a'], {}) == {'a': None}, it’s now fnc.pick(['a'], {}) == {}.

v0.1.0 (2018-08-15)

• First release.
