How to autoGenerate C bindings for Django 1.11 ?

[Etienne Robillard]

Hi,


I would like to know if it would be possible to autogenerate C bindings
for the whole Django package in Cython or similar extension.

What do you think? :)

Cheers,

Etienne

Can I create a file named libdjango.pyx with the following code:

{{{

import django

from django import *

}}}

Then compile the C file with gcc to access django in C ?

Did you try doing this and see what happens?

Not yet. But I presume I could just use the libdjango.so shared library as a replacement for the django package?

please try and share your findings, I'm sure I'm not the only one curious about this

I'm curious about this to, but am struggling to see the use case for this.  Could you elaborate on how you'd use something like this, and its expected benefits?

The goal would be to use faster C code for accessing Django internal api.

Then I suppose you could build precompiled a Django binary for specific architectures/compilers (like llvm) :)

Here is my results so far:

ImportError: dynamic module does not define init function (initmain)

erob@marina:~/src/django-hotsauce-devel/lib/libdjango$ cat libdjango.pyx

Any ideas why the dynamic module does not define init function?

Is it possible to wrap Django API into public C methods in Cython?

I'm thinking I could define a few functions in my libdjango.pyx typically used for Django administration.

What do you think?
