Motivation
----------
This project started its life as a coding challenge I was asked to solve while
interviewing in 2015 for a software engineering position at
`Uber <https://www.uber.com/careers/>`_.
After the interview proccess ended, I kept toying with the code, as a playground
to test some optimization strategies in Python. It is now a boilerplate that
I use to:
* bootstrap CLI-based projects powered with `Click <https://click.pocoo.org>`_,
* keep up with the current state-of-art of `Python packaging <https://pypa.io>`_,
* streamline the integration of a data stack (`Numpy <https://numpy.org>`_,
`Pandas <https://pandas.pydata.org>`_,
`Seaborn <https://stanford.edu/~mwaskom/software/seaborn>`_ and
`Conda <https://conda.anaconda.org>`_),
* automate `testing and quality checks <https://meta.pycqa.org>`_ (unit-tests,
coverage, coding style and packaging),
* provide an `auto-generated documentation <https://chessboard.readthedocs.io>`_.
Examples
--------
Simple 3x3 board with 2 kings and a rook:
.. code-block:: shell-session
$ chessboard solve --length=3 --height=3 --king=2 --rook=1
<SolverContext: length=3, height=3, pieces={'rook': 1, 'king': 2, 'queen': 0, 'bishop': 0, 'knight': 0}>

Famous eight queens puzzle, without printing the solutions to speed things up:
.. code-block:: shell-session
$ chessboard solve --length=8 --height=8 --queen=8 --silent
<SolverContext: length=8, height=8, pieces={'rook': 0, 'king': 0, 'queen': 8, 'bishop': 0, 'knight': 0}>
Searching positions...
92 results found in 119.87 seconds.
Huge combinatoric problem can take some time to solve:
.. code-block:: shell-session
$ chessboard solve --length=7 --height=7 --king=2 --queen=2 --bishop=2 --knight=1 --silent
<SolverContext: length=7, height=7, pieces={'rook': 0, 'king': 2, 'queen': 2, 'bishop': 2, 'knight': 1}>
Searching positions...
3063828 results found in 9328.33 seconds.
The CLI allow the production of a profiling graph, to identify code hot spots and
bottleneck:.
.. code-block:: shell-session
$ chessboard solve --length=6 --height=6 --king=2 --queen=2 --bishop=2 --knight=1 --silent --profile
<SolverContext: length=6, height=6, pieces={'rook': 0, 'king': 2, 'queen': 2, 'bishop': 2, 'knight': 1}>
Searching positions...
23752 results found in 207.25 seconds.

Third-party
-----------
This project package's boilerplate is sourced from the `code I wrote
<https://github.com/scaleway/postal-address/graphs/contributors>`_ for
`Scaleway <https://scaleway.com/>`_'s `postal-address module
<https://github.com/scaleway/postal-address>`_, which is published under a
`GPLv2+ License <https://github.com/scaleway/postal-address#license>`_.
The CLI code is based on the one I wrote for the `kdenlive-tools module
<https://github.com/kdeldycke/kdenlive-tools>`_, published under a `BSD
license <https://github.com/kdeldycke/kdenlive-tools/blob/master/LICENSE>`_.
