        Install
        =======
        
        .. code:: bash
        
                pip install python-box
        
        Box is tested on python 2.7 and 3.4+.
        If it does not install with this command, please
        open a github issue with the error you are experiencing!
        
        If you want to be able to use the `to_yaml` functionality make sure to
        install `PyYAML` or `ruamel.yaml` as well.
        
        Overview
        ========
        
        `Box` is designed to be an easy drop in transparently replacements for
        dictionaries, thanks to Python's
        duck typing capabilities, which adds dot notation access. Any sub
        dictionaries or ones set after initiation will be automatically converted to
        a `Box` object. You can always run `.to_dict()` on it to return the object
        and all sub objects back into a regular dictionary.
        
        
        .. code:: python
        
                 movie_box.movies.Spaceballs.to_dict()
                 {'director': 'Mel Brooks',
                  'imdb stars': 7.1,
                  'length': 96,
                  'personal thoughts': 'On second thought, it was hilarious!',
                  'rating': 'PG',
                  'stars': [{'imdb': 'nm0000316', 'name': 'Mel Brooks', 'role': 'President Skroob'},
                            {'imdb': 'nm0001006', 'name': 'John Candy', 'role': 'Barf'},
                            {'imdb': 'nm0001548', 'name': 'Rick Moranis', 'role': 'Dark Helmet'},
                            {'imdb': 'nm0000597', 'name': 'Bill Pullman', 'role': 'Lone Starr'}]}
        
        Box version 3 (and greater) now do sub box creation upon lookup, which means
        it is only referencing the original dict objects until they are looked up
        or modified.
        
        .. code:: python
        
              a = {"a": {"b": {"c": {}}}}
              a_box = Box(a)
              a_box
              # <Box: {'a': {'b': {'c': {}}}}>
        
              a["a"]["b"]["d"] = "2"
        
              a_box
              # <Box: {'a': {'b': {'c': {}, 'd': '2'}}}>
        
        So if you plan to keep the original dict around, make sure to box_it_up or do a deepcopy first.
        
        .. code:: python
        
              safe_box = Box(a, box_it_up=True)
              a["a"]["b"]["d"] = "2"
        
              safe_box
              # <Box: {'a': {'b': {'c': {}}}}>
        
        Limitations
        -----------
        
        `Box` is a subclass of `dict` and as such, certain keys cannot be accessed via dot notation.
        This is because names such as `keys` and `pop` have already been declared as methods, so `Box` cannot
        use it's special sauce to overwrite them. However it is still possible to have items with those names
        in the `Box` and access them like a normal dictionary, such as `my_box['keys']`.
        
        *This is as designed, and will not be changed.*
        
        The non-magic methods that exist in a `Box` are: 
        `box_it_up, clear, copy, from_json, fromkeys, get, items, keys, pop, popitem, setdefault, to_dict, to_json, update, values`.
        To view an entire list of what cannot be accessed via dot notation, run the command `dir(Box())`.
        
        
        Box
        ---
        
        `Box` can be instantiated the same ways as `dict`.
        
        .. code:: python
        
                Box({'data': 2, 'count': 5})
                Box(data=2, count=5)
                Box({'data': 2, 'count': 1}, count=5)
                Box([('data', 2), ('count', 5)])
        
                # All will create
                # <Box: {'data': 2, 'count': 5}>
        
        `Box` is a subclass of `dict` which overrides some base functionality to make
        sure everything stored in the dict can be accessed as an attribute or key value.
        
        .. code:: python
        
              small_box = Box({'data': 2, 'count': 5})
              small_box.data == small_box['data'] == getattr(small_box, 'data')
        
        All dicts (and lists) added to a `Box` will be converted on lookup to a `Box` (or `BoxList`),
        allowing for recursive dot notation access.
        
        `Box` also includes helper functions to transform it back into a `dict`,
        as well as into `JSON` or `YAML` strings or files.
        
        Conversion Box
        ~~~~~~~~~~~~~~
        
        By default, Box is now a `conversion_box`
        that adds automagic attribute access for keys that could not normally be attributes.
        It can of course be disabled with the keyword argument `conversion_box=False`.
        
        .. code:: python
        
                 movie_box.movies.Spaceballs["personal thoughts"] = "It was a good laugh"
                 movie_box.movies.Spaceballs.personal_thoughts
                 # 'It was a good laugh'
        
                 movie_box.movies.Spaceballs.personal_thoughts = "On second thought, it was hilarious!"
                 movie_box.movies.Spaceballs["personal thoughts"]
                 # 'On second thought, it was hilarious!'
        
                 # If a safe attribute matches a key exists, it will not create a new key
                 movie_box.movies.Spaceballs["personal_thoughts"]
                 # KeyError: 'personal_thoughts'
        
        Keys are modified in the following steps to make sure they are attribute safe:
        
        1. Convert to string (Will encode as UTF-8 with errors ignored)
        2. Replaces any spaces with underscores
        3. Remove anything other than ascii letters, numbers or underscores
        4. If the first character is an integer, it will prepend a lowercase 'x' to it
        5. If the string is a built-in that cannot be used, it will prepend a lowercase 'x'
        6. Removes any duplicate underscores
        
        This does not change the case of any of the keys.
        
        .. code:: python
        
                 bx = Box({"321 Is a terrible Key!": "yes, really"})
                 bx.x321_Is_a_terrible_Key
                 # 'yes, really'
        
        These keys are not stored anywhere, and trying to modify them as an
        attribute will actually modify the underlying regular key's value.
        
        **Warning: duplicate attributes possible**
        
        If you have two keys that evaluate to the same attribute, such as "a!b" and "a?b" would become `.ab`,
        there is no way to discern between them,
        only reference or update them via standard dictionary modification.
        
        
        Frozen Box
        ~~~~~~~~~~
        
        Want to show off your box without worrying about others messing it up? Freeze it!
        
        .. code:: python
        
              frigid = Box(data={'Python': 'Rocks', 'inferior': ['java', 'cobol']}, frozen_box=True)
        
              frigid.data.Python = "Stinks"
              # box.BoxError: Box is frozen
        
              frigid.data.Python
              # 'Rocks'
        
              hash(frigid)
              # 4021666719083772260
        
              frigid.data.inferior
              # ('java', 'cobol')
        
        
        It's hashing ability is the same as the humble `tuple`, it will not be hashable
        if it has mutable objects. Speaking of `tuple`, that's what all the lists
        becomes now.
        
        Default Box
        ~~~~~~~~~~~
        
        It's boxes all the way down. At least, when you specify `default_box=True` it can be.
        
        .. code:: python
        
              empty_box = Box(default_box=True)
        
              empty_box.a.b.c.d.e.f.g
              # <Box: {}>
        
              empty_box.a.b.c.d.e.f.g = "h"
              empty_box
              # <Box: {'a': {'b': {'c': {'d': {'e': {'f': {'g': 'h'}}}}}}}>
        
        Unless you want it to be something else.
        
        .. code:: python
        
              evil_box = Box(default_box=True, default_box_attr="Something Something Something Dark Side")
        
              evil_box.not_defined
              # 'Something Something Something Dark Side'
        
              # Keep in mind it will no longer be possible to go down multiple levels
              evil_box.not_defined.something_else
              # AttributeError: 'str' object has no attribute 'something_else'
        
        `default_box_attr` will first check if it is callable, and will call the object
        if it is, otherwise it will see if has the `copy` attribute and will call that,
        lastly, will just use the provided item as is.
        
        Camel Killer Box
        ~~~~~~~~~~~~~~~~
        
        Similar to how conversion box works, allow CamelCaseKeys to be found as
        snake_case_attributes.
        
        .. code:: python
        
              cameled = Box(BadHabit="I just can't stop!", camel_killer_box=True)
        
              cameled.bad_habit
              # "I just can't stop!"
        
        Ordered Box
        ~~~~~~~~~~~
        
        Preserve the order that the keys were entered into the box. The preserved order
        will be observed while iterating over the box, or calling `.keys()`,
        `.values()` or `.items()`
        
        .. code:: python
        
              box_of_order = Box(ordered_box=True)
              box_of_order.c = 1
              box_of_order.a = 2
              box_of_order.d = 3
        
              box_of_order.keys() == ['c', 'a', 'd']
        
        Keep in mind this will not guarantee order of `**kwargs` passed to Box,
        as they are inherently not ordered until Python 3.6.
        
        
        
        BoxList
        -------
        
        To make sure all items added to lists in the box are also converted, all lists
        are covered into `BoxList`. It's possible to
        initiate these directly and use them just like a `Box`.
        
        .. code:: python
        
              from box import BoxList
        
              my_boxlist = BoxList({'item': x} for x in range(10))
              #  <BoxList: [<Box: {'item': 0}>, <Box: {'item': 1}>, ...
        
              my_boxlist[5].item
              # 5
        
        
        **to_list**
        
        Transform a `BoxList` and all components back into regular `list` and `dict` items.
        
        .. code:: python
        
              my_boxlist.to_list()
              # [{'item': 0},
              #  {'item': 1},
              #  ...
        
        SBox
        ----
        
        Shorthand Box, aka SBox for short(hand), has the properties `json`, `yaml` and
        `dict` for faster access than the regular `to_dict()` and so on.
        
        .. code:: python
        
              from box import SBox
        
              sb = SBox(test=True)
              sb.json
              # '{"test": true}'
        
        Note that in this case, `json` has no default indent, unlike `to_json`.
        
        ConfigBox
        ---------
        
        A Box with additional handling of string manipulation generally found in
        config files.
        
        test_config.ini
        
        .. code:: ini
        
                [General]
                example=A regular string
        
                [Examples]
                my_bool=yes
                anint=234
                exampleList=234,123,234,543
                floatly=4.4
        
        
        With the combination of `reusables` and `ConfigBox` you can easily read python
        config values into python types. It supports `list`, `bool`, `int` and `float`.
        
        .. code:: python
        
            import reusables
            from box import ConfigBox
        
            config = ConfigBox(reusables.config_dict("test_config.ini"))
            # <ConfigBox: {'General': {'example': 'A regular string'},
            # 'Examples': {'my_bool': 'yes', 'anint': '234', 'examplelist': '234,123,234,543', 'floatly': '4.4'}}>
        
            config.Examples.list('examplelist')
            # ['234', '123', '234', '543']
        
            config.Examples.float('floatly')
            # 4.4
        
        BoxObject
        ---------
        
        An object wrapper with a **Box** for a **__dict__**.
        
        .. code:: python
        
            import requests
            from box import BoxObject
        
            def get_html(session, url, *args, **kwargs):
                response = session.get(url, *args, **kwargs)
                text = response.text
                response_meta = response.__dict__
                for key in tuple(filter(lambda k: k.startswith('_'), response_meta)):
                    response_meta.pop(key)
                return BoxObject(text, response_meta, frozen_box=True)

        **BoxObject** act just like objects but they secretly carry around a **Box** with
        them to store attributes. **BoxObject** are built off of **wrapt.ObjectProxy** which
        can wrap almost any python object. They protect their wrapped objects storing them in
        the **__wrapped__** attribute and keeping the original **__dict__** in
        **__wrapped__.__dict__**.
        
        See the `Wrapt Documentation`_, specifically
        the section on **ObjectProxy**, for more information.
