Minecraft: Pi Edition is awesome.

However it uses Python 2. We're moving it to Python 3 (without any official approval) and offering it for download here.

We hope this makes people's lives easier.

Goals

• [x] Python 3
• [ ] TESTS (pytest, tox, flake8, coverage)
• [ ] More intuitive API focusing on getting some mining done and hiding implementation details
• [ ] Backwards compatibility with the existing codebase (with __init__ foo) so existing scripts will continue to work
• [ ] Connection backends (socket, in memory for testing)
• [ ] Clever socket usage so disconnects can be dealt with
• [ ] Make the code base more readable and thus maintainable
• [ ] A CI test suite running an rPi emulator (with Travis)
• [ ] Improve code documentation both in the code base and with a RTD page
• [ ] Find missing functions that are in the java API but not described in the python API

Coding Guidelines

All code (except legacy API compatibility code) should adhere to PEP8 with some exceptions:

• Try to keep your line length below 80, but if it looks better then use up to 99 characters per line.
• You can ignore the following three PEP8 rules: E126 (continuation line over-indented for hanging indent), E127 (continuation line over-indented for visual indent), E128 (continuation line under-indented for visual indent).

You can check the code style for example by using flake8.

Some other things you should keep in mind:

• Function names should mirror ingame commands where possible.
• Group imports into three groups: First stdlib imports, then third party imports, then local imports. Put an empty line between each group.
• Backwards compatibility must be maintained unless you have a very compelling reason.
• KISS!

For backwards compatibility with Python 2, please insert this header in every Python module:

# -*- coding: utf-8 -*-
from __future__ import print_function, division, absolute_import, unicode_literals

Testing

Testing for py3minepi is set up using Tox and pytest. Violations of the coding guidelines are counted as test fails.

The only requirement to run the tests is tox:

$ pip install tox

Running tests

To run the tests on all supported Python versions, simply issue

$ tox

To test only a single Python version, use the -e parameter:

$ tox -e py32

To see the test coverage, use the cov testenv (which uses Python 3.2 by default):

$ tox -e cov

All Python versions you need to test on need to be installed of course.
