Changelog

v8.0.4 (2024-11-04)

  • Fix bug in zip_object and zip_object_deep where an empty list for keys/values would cause an exception instead of returning an empty dict.

v8.0.3 (2024-07-22)

  • Specify explicit type parameters for all type annotations. Thanks DeviousStoat!

v8.0.2 (2024-07-21)

  • Fix typing issue in map_ for compatability with chain. Thanks DeviousStoat!

v8.0.1 (2024-04-26)

  • Fix issue where too many arguments were passed to stdlib's operator.attrgetter, operator.itemgetter, and operator.methodcaller when instances of those classes were used as callbacks to functions like map_, filter_, etc. due to a bug introduced in Python 3.12.3 and 3.11.9 that reported an incorrect signature for those operator class instances.

v8.0.0 (2024-03-26)

  • Add functions (Thanks DeviousStoat!):
    • apply (previously named thru)
    • apply_catch
    • apply_if
    • apply_if_not_none
    • eq_cmp
    • gt_cmp
    • gte_cmp
    • in_range_cmp
    • is_equal_cmp
    • is_equal_with_cmp
    • is_instance_of_cmp
    • is_match_cmp
    • is_match_with_cmp
    • is_monotone_cmp
    • lt_cmp
    • lte_cmp
  • Rename function thru to apply. Thanks DeviousStoat! (breaking change)
  • Changed zip_, unzip, zip_with, unzip_with and to_pairs to accept iterables of tuples instead of lists and return lists of tuples instead of lists of lists. Thanks DeviousStoat! (breaking change)
  • Fixed bug in divide, multiply, and subtract that returned the wrong result when 0 was used as one of the operation values. Thanks DeviousStoat!

v7.0.7 (2024-01-27)

  • Fix bug in function wrappers that incorrectly computed the number of arguments the wrapped function could handle. Thanks DeviousStoat!
  • Fix bug in set_ where the incorrect object type, list instead of dict, was initialized on class attributes. Thanks DeviousStoat!
  • Drop support for Python 3.7.

v7.0.6 (2023-07-29)

  • Fix typing for chaining interface for methods that use varargs. Thanks DeviousStoat!

v7.0.5 (2023-07-06)

  • Fix typing for find_index and find_last_index by allowing predicate argument to be callback shorthand values. Thanks DeviousStoat!

v7.0.4 (2023-06-02)

  • Exclude incompatible typing-extensions version 4.6.0 from install requirements. Incompatibility was fixed in 4.6.1.

v7.0.3 (2023-05-04)

  • Fix typing for difference_by, intersection_by, union_by, uniq_by, and xor_by by allowing iteratee argument to be Any. Thanks DeviousStoat!

v7.0.2 (2023-04-27)

  • Fix issue where using pyright as a type checker with reportPrivateUsage=true would report errors that objects are not exported from pydash. Thanks DeviousStoat!

v7.0.1 (2023-04-13)

  • Fix missing install dependency, typing-extensions, for package.

v7.0.0 (2023-04-11)

  • Add type annotations to package. Raise an issue for any typing issues at https://github.com/dgilland/pydash/issues. Thanks DeviousStoat! (breaking change)
  • Change behavior of to_dict to not using dict() internally. Previous behavior would be for something like to_dict([["k", "v"], ["x", "y"]]) to return {"k": "v", "x": "y"} (equivalent to calling dict(...)) but to_dict([["k"], ["v"], ["x"], ["y"]]) would return {0: ["x"], 1: ["v"], 2: ["x"], 3: ["y"]}. The new behavior is to always return iterables as dictionaries with their indexes as keys like {0: ["k", "v"], 1: ["x", "y"]}. This is consistent with how iterable objects are iterated over and means that to_dict will have more reliable output. (breaking change)
  • Change behavior of slugify to remove single-quotes from output. Instead of slugify("the cat's meow") == "the-cat's-meow", the new behavior is to return "the-cats-meow". (breaking change)
  • Add support for negative indexes in get path keys. Thanks bl4ckst0ne!

v6.0.2 (2023-02-23)

  • Only prevent access to object paths containing __globals__ or __builtins__ instead of all dunder-methods for non-dict/list objects.

v6.0.1 (2023-02-20)

  • Fix exception raised due to mishandling of non-string keys in functions like get() for non-dict/list objects that used integer index references like "[0]".

v6.0.0 (2023-01-28)

  • Prevent access to object paths containing dunder-methods in functions like get() for non-dict/list objects. Attempting to access dunder-methods using get-path keys will raise a KeyError (e.g. get(SomeClass(), '__init__' will raise). Access to dict keys are unaffected (e.g. get({"__init__": True}, "__init__") will return True). (breaking change)
  • Add support for Python 3.11.
  • Drop support for Python 3.6 (breaking change)

v5.1.2 (2022-11-30)

  • Remove unnecessary type check and conversion for exceptions argument in pydash.retry.

v5.0.2 (2021-07-15)

  • Fix compatibility issue between pydash.py_ / pydash._ and typing.Protocol + typing.runtime_checkable that caused an exception to be raised for isinstance(py_, SomeRuntimeCheckableProtocol).

v5.0.1 (2021-06-27)

  • Fix bug in merge_with that prevented custom iteratee from being used when recursively merging. Thanks weineel!

v5.0.0 (2021-03-29)

  • Drop support for Python 2.7. (breaking change)
  • Improve Unicode word splitting in string functions to be inline with Lodash. Thanks mervynlee94! (breaking change)

    • kebab_case
    • lower_case
    • pascal_case
    • separator_case
    • slugify
    • snake_case
    • start_case
    • upper_case
  • Optimize regular expression constants used in pydash.strings by pre-compiling them to regular expression pattern objects.

v4.9.2 (2020-12-24)

  • Fix regression introduced in v4.9.1 that broke pydash.get for dictionaries and dot-delimited keys that reference integer dict-keys.

v4.9.1 (2020-12-14)

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

v4.9.0 (2020-10-27)

  • Fix exception in order_by when None used as a sort key. Thanks elijose55!
  • Fix behavior of pick_by to return the passed in argument when only one argument given. Previously, an empty dictionary was returned. Thanks elijose55!
  • Officially support Python 3.8.

v4.7.6 (2019-11-20)

Bug Fixes

  • Fix handling of Sequence, Mapping, and namedtuple types in get so that their attributes aren't accessed during look-up. Thanks jwilson8767!

v4.7.3 (2018-08-07)

Bug Fixes

  • Fix bug in spread where arguments were not being passed to wrapped function properly.

v4.7.1 (2018-08-03)

New Features

  • Modify to_dict to first try to convert using dict() before falling back to using pydash.helpers.iterator().

v4.7.0 (2018-07-26)

Misc

  • Internal code optimizations.

v4.6.1 (2018-07-16)

Misc

  • Support Python 3.7.

New Features

  • Add jitter argument to retry.

v4.4.1 (2018-03-14)

New Features

  • Add attempt argument to on_exception callback in retry. New function signature is on_exception(exc, attempt) (previously was on_exception(exc)). All arguments to on_exception callback are now optional.

v4.4.0 (2018-03-13)

New Features

  • Add retry decorator that will retry a function multiple times if the function raises an exception.

v4.3.3 (2018-03-02)

Bug Fixes

  • Fix regression in v4.3.2 introduced by the support added for callable class callbacks that changed the handling of callbacks that could not be inspected. Prior to v4.3.2, these callbacks would default to being passed a single callback argument, but with v4.3.2 these callbacks would be passed the full set of callback arguments which could result an exception being raised due to the callback not supporting that many arguments.

v4.3.2 (2018-02-06)

Bug Fixes

  • Fix issue in defaults_deep where sources with non-dict values would raise an exception due to assumption that object was always a dict.
  • Fix issue in curry where too many arguments would be passed to the curried function when evaluating function if too many arguments used in last function call.
  • Workaround issue in Python 2.7 where callable classes used as callbacks were always passed the full count of arguments even when the callable class only accept a subset of arguments.

v4.3.1 (2017-12-19)

    • pick
    • pick_by
    • set_
    • transpose
    • zip_object_deep

v4.3.0 (2017-11-22)

  • Wrap non-iterables in a list in to_list instead of raising an exception. Thanks efenka!
  • Add split_strings argument to to_list to control whether strings are coverted to a list (split_strings=True) or wrapped in a list (split_strings=False). Default is split_strings=True. Thanks efenka!

v4.2.1 (2017-09-08)

Bug Fixes

  • Ensure that to_path always returns a list.
  • Fix get to work with path values other than just strings, integers, and lists.

v4.2.0 (2017-09-08)

New Features

  • Support more iterator "hooks" in to_dict so non-iterators that expose an items(), iteritems(), or has __dict__ attributes will be converted using those methods.
  • Support deep paths in omit and omit_by. Thanks beck3905!
  • Support deep paths in pick and pick_by. Thanks beck3905!

Bug Fixes

  • Fix missing argument passing to matched function in cond.
  • Support passing a single list of pairs in cond instead of just pairs as separate arguments.

v4.1.0 (2017-06-09)

New Features

  • Officially support Python 3.6.
  • Add properties function that returns list of path values for an object.
  • Add replace_end.

Bug Fixes

  • None

v4.0.4 (2017-05-31)

New Features

  • None

Bug Fixes

v4.0.3 (2017-04-20)

New Features

  • None

Bug Fixes

  • Fix regression in get where list and dict objects had attributes returned when a key was missing but the key corresponded to an attribute name. For example, pydash.get({}, 'update') would return {}.update() instead of None. Previous behavior was that only item-access was allowed for list and dict which has been restored.
  • Fix regression in invoke/invoke_map where non-attributes could be invoked. For example, pydash.invoke({'items': lambda: 1}, 'items') would return 1 instead of dict_items([('a', 'items')]). Previous behavior was that only attribute methods could be invoked which has now been restored.

v4.0.2 (2017-04-04)

New Features

  • None

Bug Fixes

  • Fix regression in intersection, intersection_by, and intersection_with introduced in v4.0.0 where the a single argument supplied to intersection should return the same argument value instead of an empty list.

Backwards-Incompatibilities

  • None

v4.0.1 (2017-04-04)

New Features

  • Make property_ work with deep path strings.

Bug Fixes

  • Revert removal of deep_pluck and rename to pluck. Previously, deep_pluck was removed and map_ was recommended as a replacement. However, deep_pluck (now defined as pluck) functionality is not supported by map_ so the removal pluck was reverted.

Backwards-Incompatibilities

  • Remove property_deep (use property_).

v4.0.0 (2017-04-03)

v3.4.8 (2017-01-05)

  • Make internal function inspection methods work with Python 3 annotations. Thanks tgriesser!

v3.4.7 (2016-11-01)

  • Fix bug in get where an iterable default was iterated over instead of being returned when an object path wasn't found. Thanks urbnjamesmi1!

v3.4.6 (2016-10-31)

  • Fix bug in get where casting a string key to integer resulted in an uncaught exception instead of the default value being returned instead. Thanks urbnjamesmi1!

    • Eliminate usage of costly guess_builtin_argcount which parsed docstrings, and instead only ever pass a single argument to a builtin callback function.
  • Optimize get/set so that regex parsing is only done when special characters are contained in the path key whereas before, all string paths were parsed.
  • Optimize is_builtin by checking for BuiltinFunctionType instance and then using dict look up table instead of a list look up.
  • Optimize is_match by replacing call to has with a try/except block.
  • Optimize push/append by using a native loop instead of callback mapping.

    • replace
    • series_phrase
    • series_phrase_serial
    • starts_with
    • surround
  • Make callback invocation have better support for builtin functions and methods. Previously, if one wanted to pass a builtin function or method as a callback, it had to be wrapped in a lambda which limited the number of arguments that would be passed it. For example, _.each([1, 2, 3], array.append) would fail and would need to be converted to _.each([1, 2, 3], lambda item: array.append(item). That is no longer the case as the non-wrapped method is now supported.
