Stub generation for Cython code.

Install the package with pip install stubgen-pyx.

From the command line:

stubgen-pyx /path/to/package

Or from Python:

import stubgen_pyx
stubgen_pyx.stubgen("/path/to/package")

Cython is a popular Python extension language, but introspection for Cython modules is often limited. .pyi files are a common way to provide type hints for Python code that cannot be easily analyzed statically.

mypy is a static type checker for Python that can generate .pyi files for extension modules at a pretty good level of accuracy. However, it's not designed to utilize embedded information about Cython module members - this leaves the .pyi files quite limited.

• cimport-ed modules with types that leak into the stub file (by way of function signatures, for example) do not have their imports followed in the stub file. As a workaround, you can set a __cimport_types__ list or tuple of module types that you want exposed to the stub file.

• This is only designed to be a pretty good approximation of Python-public members in a Cython module. It's still very much a work in progress and may produce inaccurate results. If you notice any bugs or have any suggestions, please open an issue.
