Мне нужно получить список имен функций и сигнатур по файлу python. Функция Python inspect.signature
может дать мне подпись функции. Но inspect.signature
нужен функциональный объект (PyFunctionObject
). inspect.getmembers
может вернуть такой объект. Но если я задаю PyFunctionObject
как элемент в PyTuple
, когда выполняется Py_Finalize
- я получаю ошибку. Также я использую Qt.
Итак, строка PyTuple_SetItem(pFuncLink_arg, 0, pGetmember_tupleList);
ошибка результата.
Код:.
PyObject *pName, *pModule;
PyObject *pInspect_module_name, *pInspect_module;
PyObject *pGetmember_function, *pGetmember_call_args, *pGetmembers_reply, *pGetsignature_function, *pGetmember_itemList, *pGetmember_tupleList;
PyObject *pFuncName, *pFuncLink_arg, *pFuncSign;
Py_Initialize();
QFileInfo fileInfo(QFile("X:/Projects/p-text.py"));
QString absPath = fileInfo.absolutePath();
QString fileName = fileInfo.baseName();
PyObject* sysPath = PySys_GetObject((char*)"path");
PyObject* programName = PyUnicode_FromString(absPath.toAscii());
PyList_Append(sysPath, programName);
pName = PyUnicode_FromString(fileName.toLatin1());
pModule = PyImport_Import(pName);
Py_DECREF(pName);
if (pModule != NULL){
pInspect_module_name = PyUnicode_DecodeFSDefault("inspect");
pInspect_module = PyImport_Import(pInspect_module_name);
pGetmember_function = PyObject_GetAttrString(pInspect_module, "getmembers");
pGetsignature_function = PyObject_GetAttrString(pInspect_module, "signature");
pGetmember_call_args = PyTuple_New(1);
PyTuple_SetItem(pGetmember_call_args, 0, pModule);
pGetmembers_reply = PyObject_CallObject(pGetmember_function, pGetmember_call_args);
if (pGetmembers_reply){
Py_ssize_t const num_args = PyList_Size(pGetmembers_reply);
for (Py_ssize_t i = 0; i < num_args; ++i){
pGetmember_itemList = PyList_GetItem(pGetmembers_reply, i);
pGetmember_tupleList = PyTuple_GetItem(pGetmember_itemList, 1);
if (PyFunction_Check(pGetmember_tupleList)){
pFuncName = PyTuple_GetItem(pGetmember_itemList, 0);
QString funcName = PyObjectToString(pFuncName);
Py_DECREF(pFuncName);
pFuncLink_arg = PyTuple_New(1);
PyTuple_SetItem(pFuncLink_arg, 0, pGetmember_tupleList);
pFuncSign = PyObject_CallObject(pGetsignature_function, pFuncLink_arg);
if (pFuncSign == NULL) {
if (PyErr_Occurred()) {
PyErr_Print();
}
return;
}
QString funcSign = PyObjectToString(pFuncSign);
Py_DECREF(pFuncSign);
cout<<funcSign.toStdString()<<endl;
}
Py_DECREF(pGetmember_tupleList);
Py_DECREF(pGetmember_itemList);
}
}
Py_DECREF(pInspect_module_name);
Py_DECREF(pInspect_module);
Py_DECREF(pGetmember_function);
Py_DECREF(pGetsignature_function);
Py_DECREF(pGetmember_call_args);
}
else {
PyErr_Print();
}
Py_Finalize();
Py_Finalize()
выдает ошибку "project_name.exeсработал точку останова "
