prawcore is a low-level communication layer for PRAW 4+.


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

Install prawcore using ``pip`` via:

.. code-block:: console

    pip install prawcore


Execution Example
-----------------

The following example demonstrates how to use prawcore to obtain the list of
trophies for a given user using the script-app type.  This example assumes you
have the environment variables ``PRAWCORE_CLIENT_ID`` and
``PRAWCORE_CLIENT_SECRET`` set to the appropriate values for your application.

.. code-block:: python

   #!/usr/bin/env python
   import os
   import pprint
   import prawcore

   authenticator = prawcore.TrustedAuthenticator(
       prawcore.Requestor('YOUR_VALID_USER_AGENT'),
       os.environ['PRAWCORE_CLIENT_ID'],
       os.environ['PRAWCORE_CLIENT_SECRET'])
   authorizer = prawcore.ReadOnlyAuthorizer(authenticator)
   authorizer.refresh()

   with prawcore.session(authorizer) as session:
       pprint.pprint(session.request('GET', '/api/v1/user/bboe/trophies'))

Save the above as ``trophies.py`` and then execute via:

.. code-block:: console

   python trophies.py

Depending on prawcore
---------------------

prawcore follows `semantic versioning <http://semver.org/>`_ with the exception
that deprecations will not be preceded by a minor release. In essense, expect
only major versions to introduce breaking changes to prawcore's public
interface. As a result, if you depend on prawcore then it is a good idea to
specify not only the minimum version of prawcore your package requires, but to
also limit the major version.

Below are two examples of how you may want to specify your prawcore dependency:

setup.py
~~~~~~~~

.. code-block:: python

   setup(...,
         install_requires=['prawcore >=0.1, <1'],
         ...)

requirements.txt
~~~~~~~~~~~~~~~~

.. code-block:: text

   prawcore >=1.5.1, <2
