cython: how to package a python module? - cython

Question

For example, I have a python module, and the structure is
moduleA
__init__.py
functionA.py
moduleB
__init__.py
functionB.py
setup.py
How can I package the moduleA using cython?
What I have tested:
test
__init__.py
foo.py
setup.py
#----------------------------------------------------
## __init__.py
from foo import *
#---------------------------------------------------
## foo.py
def hello():
print("hello")
# ----------------------------------------------------------
## setup.py
from setuptools import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext
ext_modules = [
Extension('test.foo', ['test/foo.py']),
]
setup(
name='Test',
ext_modules=ext_modules,
include_dirs=["test"],
cmdclass={'build_ext': build_ext},
)
After python setup.py build_ext, a new fold appear:
build
lib.win-amd64-3.7
test
foo.cp37-win_amd64.pyd
temp.win-amd64-3.7
Release
test
foo.cp37-win_amd64.exp
foo.cp37-win_amd64.lib
foo.obj
Then, cd ./build/lib.win-amd64-3.7, and open python interpreter. import test is OK, but I can use hello() by test.hello(), test.foo.hello(), test.foo().
What's wrong with my process?
The environment is:
win 10
python 3.7
cython 0.29.26
Update----------------------------------------------------
The above problem can be solved by `python setup.py build_ext --inplace'. Thanks for DavidW's suggestion.
My next question is how to pack a python module?
For example, I have a module as:
App
ModuleA
__init__.py
funcA.py
ModuleB
__init__.py
funcB.py
__init__.py
setup.py
I can pack the aoove module by the following setup.py:
from setuptools import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext
ext_modules = [
Extension('App.ModuleA.funcA', ['App/ModuleA/funcA.py']),
Extension('App.ModuleB.funcB', ['App/ModuleB/funcB.py']),
]
setup(
name='App',
ext_modules=ext_modules,
include_dirs=["App"],
cmdclass={'build_ext': build_ext},
)
I manually collect the ext_modules. But, if the module has many file, how can I automatically collect the ext_modules?
I can only write the following stranger code:
name = 'App.'
moduleName = os.listdir('./App')
for mName in moduleName:
name += mName
...
Is there any other elegant methods?
