Python bindings to libpurple.

This is Flare's attempt at reviving python-purple. The library was forked from fahhem/python-purple, which was a short-lived fork of Anderson Briglia's original work.

Notable changes since then include:

• Moving to Python 3
• Adding tests
• (ongoing) Refactoring the API
• Type annotations for use with mypy.
• High-level PurpleClient for an easier-to-use API.

No API stability promises are made at this time. However, whatever is tested (see purple/tests) can be considered somewhat stable.

See simpleclient.py for usage examples.

python-purple tests use libpurple's null protocol. Your distro probably does not ship it by default. For guidance on how to build it yourself, take a look at .travis.yml.

• test: Run all tests.
• format: Format the source code with black.
• run-simpleclient: Run simpleclient from the virtualenv.

Here are some notes that may help you while working on python-purple. I found that some of these things are not entirely obvious so it may help to read them before getting started.

• Cast char* to bytes safely using cdef bytes py_variable = c_variable or None

• Use kwargs for all callbacks.
• Strings should be used instead of bytes wherever it makes sense.
• Good test coverage.
