Elegant implementation of Enum which inherits from str or bytes

As simple as this
-----------------

.. code-block:: python

   from anystrenum import StrEnum

   class Season(StrEnum):
       spring: str
       summer: str
       autumn: str
       winter: str

   print(Season.summer)
   print(isinstance(Season.summer, str))
   # summer
   # True

Features
========


* Easy members assignment with type hinting (No need to use ``auto()`` or other stubs)
* Automatic value generation with support of custom converters or separators
* Method to filter members (\ ``contains``\ , ``contained_in``\ , ``startswith``\ , ``endswith``\ , etc.)
* Custom ``str`` and ``bytes`` types support

Installation
============

.. code-block:: bash

   $ pip install AnyStrEnum

Examples
========

Using custom words separator
----------------------------

To automatically replace all underscores (\ ``_``\ ) in names to something more suitable, use ``sep`` parameter:

.. code-block:: python

   from anystrenum import StrEnum

   class Region(StrEnum, sep='-'):
       us_east_1: str
       us_west_1: str
       ca_central_1: str
       cn_northwest_1: str
       eu_central_1: str
       eu_west_1: str
       eu_north_2: str
       sa_east_1: str

   print(Region.us_east_1)
   # us-east-1

Using str converter and custom words separator
----------------------------------------------

If you need to apply to your names more changes, you can use ``converter`` parameter. Pass a function in here which will be called on every member

.. code-block:: python

   from anystrenum import StrEnum

   class ContentType(StrEnum, converter=lambda s: s.replace('_', '/', 1), sep='-'):
       application_json: str
       application_octet_stream: str
       application_x_json_stream: str
       audio_mpeg: str
       audio_pcm: str
       audio_ogg: str

   print(ContentType.application_octet_stream)
   # application/octet-stream

As you can see from an example, firstly, names will be converted with our lambda function and then, 
remaining underscores will be replaced with given separator

Filtering enum members
----------------------

Using enums from previous examples
##################################

.. code-block:: python

   print(ContentType.filter(contains='-', startswith='a', endswith='m'))
   # {<ContentType.application_octet_stream: 'application/octet-stream'>, 
   # <ContentType.application_x_json_stream: 'application/x-json-stream'>}

   print(ContentType.filter(contained_in='Usually content type for MP3 is audio/mpeg'))
   # {<ContentType.audio_mpeg: 'audio/mpeg'>}

   print(Region.filter(startswith='eu', endswith='1'))
   # {<Region.eu_west_1: 'eu-west-1'>, <Region.eu_central_1: 'eu-central-1'>}
