However sometimes you have to run the embedded Python interpreter in the same thread as your rest application and you can't allow the -:c:func:`PyRun_InteractiveLoop` to stop while waiting for user input. The one -solution then is to call :c:func:`PyParser_ParseString` and test for ``e.error`` -equal to ``E_EOF``, which means the input is incomplete. Here's a sample code -fragment, untested, inspired by code from Alex Farber:: - - #define PY_SSIZE_T_CLEAN - #include <Python.h> - #include <node.h> - #include <errcode.h> - #include <grammar.h> - #include <parsetok.h> - #include <compile.h> - - int testcomplete(char *code) - /* code should end in \n */ - /* return -1 for error, 0 for incomplete, 1 for complete */ - { - node *n; - perrdetail e; - - n = PyParser_ParseString(code, &_PyParser_Grammar, - Py_file_input, &e); - if (n == NULL) { - if (e.error == E_EOF) - return 0; - return -1; - } - - PyNode_Free(n); - return 1; - } - -Another solution is trying to compile the received string with +:c:func:`PyRun_InteractiveLoop` to stop while waiting for user input. +A solution is trying to compile the received string with :c:func:`Py_CompileString`. If it compiles without errors, try to execute the returned code object by calling :c:func:`PyEval_EvalCode`. Otherwise save the input for later. If the compilation fails, find out if it's an error or just |
