Subpackage Descriptions
single JMESPath ======== JMESPath (pronounced "james path") allows you to declaratively specify how to extract elements from a JSON document. For example, given this document:: {"foo": {"bar": "baz"}} The jmespath expression ``foo.bar`` will return "baz". JMESPath also supports: Referencing elements in a list. Given the data:: {"foo": {"bar": ["one", "two"]}} The expression: ``foo.bar[0]`` will return "one". You can also reference all the items in a list using the ``*`` syntax:: {"foo": {"bar": [{"name": "one"}, {"name": "two"}]}} The expression: ``foo.bar[*].name`` will return ["one", "two"]. Negative indexing is also supported (-1 refers to the last element in the list). Given the data above, the expression ``foo.bar[-1].name`` will return "two". The ``*`` can also be used for hash types:: {"foo": {"bar": {"name": "one"}, "baz": {"name": "two"}}} The expression: ``foo.*.name`` will return ["one", "two"]. Installation ============ You can install JMESPath from pypi with: .. code:: bash pip install jmespath API === The ``jmespath.py`` library has two functions that operate on python data structures. You can use search and give it the jmespath expression and the data: .. code:: python >>> import jmespath >>> path = jmespath.search('foo.bar', {'foo': {'bar': 'baz'}}) 'baz' Similar to the re module, you can use the compile function to compile the JMESPath expression and use this parsed expression to perform repeated searches: .. code:: python >>> import jmespath >>> expression = jmespath.compile('foo.bar') >>> expression.search({'foo': {'bar': 'baz'}}) 'baz' >>> expression.search({'foo': {'bar': 'other'}}) 'other' This is useful if you're going to use the same jmespath expression to search multiple documents. This avoids having to reparse the JMESPath expression each time you search a new document. Options ------- You can provide an instance of ``jmespath.Options`` to control how a JMESPath expression is evaluated. The most common scenario for using an Options instance is if you want to have ordered output of your dict keys. To do this you can use either of these options: .. code:: python >>> import jmespath >>> jmespath.search('{a: a, b: b}', ... mydata, ... jmespath.Options(dict_cls=collections.OrderedDict)) >>> import jmespath >>> parsed = jmespath.compile('{a: a, b: b}') >>> parsed.search(mydata, ... jmespath.Options(dict_cls=collections.OrderedDict)) Custom Functions ~~~~~~~~~~~~~~~~ The JMESPath language has numerous `built-in functions
