Cythonizing and creating cpp code question

[Randall]

Hi all:

I am looking at the pyx code now but it seems I am going to have to understand how the cython interpreter works in order to push back up the changes in the cpp code which I did to clear up all the warning messages.

Example (the free_algebra_letterplace.pyx --> free_algebra_letterplace.cpp)

owner@localhost:~/sage/sage-9.5> vim ./src/sage/algebras/letterplace/free_algebra_letterplace.pyx

Is the location of the source pyx --> object cpp code if I am understanding how this translator works.

owner@localhost:~/sage/sage-9.5> vim ./pkgs/sagemath-standard/build/cythonized/sage/algebras/letterplace/free_
algebra_letterplace.cpp 

is the location of the object cpp code (I trust)

I did make a small change in the pyx code, but did NOT get what I expected to see in the cpp code (so I have a learning curve ahead of me)

Any cynthonizing experts here?

I will poke around looking for the cython documents and see how this translator works.

What I see happening in my 105 cpp files is variables NOT being initialized correctly. But this change has to come from the cythonizer, not by changing the cpp code itself.
