* For indentation, use *four space characters* per level of indentation. Keep
lines under the 80 chars limit (only exception are the functions definition)
* When comparing C pointers with NULL, use == and != instead of the python
operator "is". This makes a visual distinction between python and C code.
* From "The Zen of Python":
Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Special cases aren't special enough to break the rules.
Although practicality beats purity.
Errors should never pass silently.
Unless explicitly silenced.
In the face of ambiguity, refuse the temptation to guess.
There should be one-- and preferably only one --obvious way to do it.
Although that way may not be obvious at first unless you're Dutch.
Now is better than never.
Although never is often better than *right* now.
If the implementation is hard to explain, it's a bad idea.
If the implementation is easy to explain, it may be a good idea.
Namespaces are one honking great idea -- let's do more of those!
* cython -a will generate a report that shows your cython code, and each line
can be expanded by clicking to show the generated C code. This cannot be done
from the setup script, it has to be called manually on a .pyx file.
* cython does automatic dict <-> struct conversion with basic struct members
* Use a decorator for _METHOD_DEPRECATED
* Internal utility functions used in the bindings must start with an
underscore and must have the shortest name as possible.
This needs further discussion/expansion.
When we define a function with cdef it is not exposed to Python API.
This should be explicit enough to not need the underscore prefix, which
at best looks ugly, and at worst just plain confusing.
A function name should summarize its functionality in one clear text,
short sentence. We have both too long and too short names. And I admit to
being guilty of adding many of both.
Let's build up a short review so we can see where we stand with this and
make necessary corrections.
The underscore usage is a coding standard in all the EFL, we should try
to follow the efl style also here (where is possible and make sense)
