• Delinting and package refresh.

v5.0.0

Features

• Moved collections into a package and declared as typed.

Deprecations and Removals

• Removed DictFilter.

v4.3.0

Features

• Require Python 3.8 or later.

v4.2.0

Added Mask, the inverse of a Projection.

v4.1.0

Projection now accepts an iterable or callable or pattern for matching keys.

Projection now retains order of keys from the underlying mapping.

DictFilter is now deprecated in favor of Projection.

v4.0.0

DictFilter no longer accepts include_keys and requires include_pattern as a keyword argument.

v3.11.0

In DictFilter, deprecated include_keys parameter and usage without include_pattern. Future versions will honor include_pattern as a required keyword argument. All other uses are deprecated. For uses that currently rely on include_keys, use Projection instead/in addition. For example, instead of:

filtered = DictFilter(orig, include_keys=['a'], include_pattern='b+')

Use:

filtered = DictFilter(Projection(['a'], orig), include_pattern='b+')

v3.10.0

In Projection, harmonize the implementation and optimize using set instead of tuple.

v3.9.0

DictFilter.__len__ no longer relies on the iterable. Improves efficiency and fixes RecursionError on PyPy (#12).

v3.8.0

Made DictStack mutable.

v3.7.0

Added RangeMap.left.

v3.6.0

Revised DictFilter:

• Fixed issue where DictFilter.__contains__ would raise a KeyError.

• Relies heavily now on collections.abc.Mapping base class.

v3.5.2

Packaging refresh.

Enrolled with Tidelift.

v3.5.1

Fixed DictStack.__len__ and addressed recursion error on PyPy in __getitem__.

v3.5.0

DictStack now supports the following Mapping behaviors:

• .items()

• casting to a dict

• __contains__ (i.e. “x in stack”)

Require Python 3.7 or later.

v3.4.0

Add WeightedLookup.

v3.3.0

Add FreezableDefaultDict.

v3.2.0

Rely on PEP 420 for namespace package.

v3.1.0

Refreshed packaging. Dropped dependency on six.

v3.0.0

Require Python 3.6 or later.

2.1

Added pop_all function.

2.0

Switch to pkgutil namespace technique for the jaraco namespace.

1.6.0

Fix DeprecationWarnings when referencing abstract base classes from collections module.

1.5.3

Refresh package metadata.

1.5.2

Fixed KeyError in BijectiveMap when a new value matched an existing key (but not the reverse). Now a ValueError is raised as intended.

1.5.1

Refresh packaging.

1.5

Added a Projection class providing a much simpler interface than DictFilter.

1.4.1

#3: Fixed less-than-equal and greater-than-equal comparisons in Least and Greatest.

1.4

Added Least and Greatest classes, instances of which always compare lesser or greater than all other objects.

1.3.2

Fixed failure of KeyTransformingDict to transform keys on calls to .get.

1.3

Moved hosting to Github.

1.2.2

Restore Python 2.7 compatibility.

1.2

Add InstrumentedDict.

1.1

Conditionally require setup requirements.

1.0

Initial functionality taken from jaraco.util 10.8.
