Data URI manipulation made easy.

This isn't very robust, and will reject a number of valid data URIs. However, it meets the most useful case: a mimetype, a charset, and the base64 flag.

Installation
------------

.. code-block:: bash

$ pip install python-datauri

Parsing
-------

.. code-block:: python

>>> from datauri import DataURI
>>> uri = DataURI('data:text/plain;charset=utf-8;base64,VGhlIHF1aWNrIGJyb3duIGZveCBqdW1wZWQgb3ZlciB0aGUgbGF6eSBkb2cu')
>>> uri.mimetype
'text/plain'
>>> uri.charset
'utf-8'
>>> uri.is_base64
True
>>> uri.data
b'The quick brown fox jumped over the lazy dog.'

Note that ``DataURI.data`` will always return bytes.
Use ``DataURI.text`` to get a string.

Creating from a string
----------------------

.. code-block:: python

>>> from datauri import DataURI
>>> made = DataURI.make('text/plain', charset='us-ascii', base64=True, data='This is a message.')
>>> made
DataURI('data:text/plain;charset=us-ascii;base64,VGhpcyBpcyBhIG1lc3NhZ2Uu')
>>> made.data
b'This is a message.'

Creating from a file
--------------------

This is really just a convenience method.

.. code-block:: python

>>> from datauri import DataURI
>>> png_uri = DataURI.from_file('somefile.png')
>>> png_uri.mimetype
'image/png'
>>> png_uri.data
b'\x89PNG\r\n...'

Serializing
-----------

`DataURI` is a subclass of `str`, so you can just use `str()` to print it out:

.. code-block:: python

>>> from datauri import DataURI
>>> png_uri = DataURI.from_file('somefile.png')
>>> str(png_uri)
'data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAASABIA...'

Pydantic Support
----------------

You can use `DataURI` as a type for `Pydantic`:

.. code-block:: python

from datauri import DataURI
from pydantic import BaseModel

class ProfilePicture(BaseModel):
image_data: DataURI
