A Python `dict` with a merge() method.

Project description

mergedict - A Python dict with a merge() method

https://travis-ci.org/schettino72/mergedict.png?branch=master https://coveralls.io/repos/schettino72/mergedict/badge.png

A MergeDict is a dict with a merge() method. merge() is like dict.update()

from mergedict import MergeDict

d1 = MergeDict({'a': 1, 'b': 'one'})
d1.merge({'a':2, 'c': [2]})

assert d1 == {'a': 2, 'c': [2], 'b': 'one'}

A MergeDict can be subclassed to create custom “merge” operations based on the type of an item value.

from mergedict import MergeDict

class SumDict(MergeDict):
      @MergeDict.dispatch(int)
      def merge_int(this, other):
          return this + other

d2 = SumDict({'a': 1, 'b': 'one'})
d2.merge({'a':2, 'b': 'two'})

assert d2 == {'a': 3, 'b': 'two'}

mergedict module comes with a ConfigDict that will extend/update lists/sets/dicts.

from mergedict import ConfigDict

d3 = ConfigDict({'a': 1, 'my_list': [1, 2]})
d3.merge({'a':2, 'my_list': [3, 4]})

assert d3 == {'a': 2, 'my_list': [1, 2, 3, 4]}
