kmatch: A language for matching Python dictionaries =================================================== The kmatch library provides a language for matching Python dictionaries. Patterns are specified as lists of filters combined with logical operators. A quick example of kmatch is below. .. code-block:: python from kmatch import K k = K(['>=', 'k', 10]) print k.match({'k': 9}) False print k.match({'k': 10}) True More powerful expressions can be made to match more types of patterns. .. code-block:: python from kmatch import K k = K(['&', ['=~', 'k1', '.*Hello.*'], ['!=', 'k2', False] ]) # Match all a dictionary whose 'k1' key has a pattern of '.*Hello.*' and whose 'k2' key is not False k.match(...) The kmatch library can be used for a wide variety of applications. One example is filtering a list of dictionaries that match a pattern. Another example is to validate dictionaries passed to a function. Documentation ------------- Full documentation is available at http://kmatch.readthedocs.org
