Practice cython wrapping of C++

This short project is just to gain some experience on wrapping C++ code with Cython.

It contains basic representation of crossfit workouts/metcons, as well as a means a representation of the movements involded.

Usage

The following two samples show how to create a For Time wod Murph, and an AMRAP, Mary, as well as their representation.

Murph:

>>> import wodext as wod
>>> murph = wod.PyForTime("Murph", time_cap=50)
>>> movements = [
...     wod.PyMovement("run", distance=1600),
...     wod.PyMovement("pull-up", reps=100),
...     wod.PyMovement("push-up", reps=200),
...     wod.PyMovement("air squat", reps=300),
...     wod.PyMovement("run", distance=1600)
... ]
>>> for mov in movements:
>>>     murph.add(mov)
>>> print(murph)
PyForTime
---------
- run 1600.0 m
- pull-up, reps: 100
- push-up, reps: 200
- air squat, reps: 300
- run 1600.0 m
---------

Mary:

>>> mary = wod.PyAMRAP("Mary", time=20)
>>> movements = [
...     wod.PyMovement("hspu", reps=5),
...     wod.PyMovement("pistols", reps=10),
...     wod.PyMovement("pull-up", reps=15)
... ]
>>> 
>>> for mov in movements:
...     mary.add(mov)
>>> print(mary)
PyAMRAP
-------
- hspu, reps: 5
- pistols, reps: 10
- pull-up, reps: 15
-------

How To guide

Install the dependencies in a new virtual environment:

pip install -r requirements.txt

Build the extension:

make compile

Run the unit tests:

make test

If everything worked properly, the extension is importable from python as wodext.
