Compile and Link C-API modules on Import

Project Description

🐚 About

c is a Python project providing a metapath hook for loading C extension modules without prior compilation by a ‘setup.py’ script. It uses the sysconfig module to extract the necessary information for compiling an extension module.

Loadable modules are identified by the ‘.py.c’, ‘.py.m’, and ‘.py.c++’ suffix. Composition of multiple files is not directly supported, but preprocessor directives may be used in order to combine multiple files.

Sample

Typical usage:

>>> import package.libfoo
>>> package.libfoo.return_true()
True

Where:

package/
        __init__.py
        libfoo.py.c

libfoo.py.c:

/*
 * libfoo.py.c - test library for the c loader
 */
#include <Python.h>
#include <structmember.h>

static PyObject *
return_true(PyObject *self)
{
        Py_INCREF(Py_True);
        return(Py_True);
}

/* METH_O, METH_VARARGS, METH_VARKEYWORDS, METH_NOARGS */
static PyMethodDef methods[] = {
        {"return_true", (PyCFunction) return_true, METH_NOARGS, "return `True`"},
        {NULL}
};

static struct PyModuleDef module = {
        PyModuleDef_HEAD_INIT,
        "package.libfoo",       /* name of module */
        NULL,                                   /* module documentation, may be NULL */
        -1,                                     /* size of per-interpreter state of the module,
                                                                or -1 if the module keeps state in global variables. */
        methods,
};

PyMODINIT_FUNC
PyInit_libfoo(void)
{
        PyObject *mod;
        mod = PyModule_Create(&module);
        return(mod);
}
