How do I run a python file that is read into a std::string using PyRun

Question

I am embedding Python into my C++ program, and have used PyRun_SimpleString quite effectively but now am having trouble.

What I have done is loaded a python.py file a st

Answer 1

I solved my problem by using a string vector and reading each line of the file into the vector, then executing each one using PyRun_SimpleString.

Here's the finished code, no error checking though. std::vector string_vector; std::string content; if(python_script.empty()) return true;

    ail::read_lines(python_script, string_vector);

    if(!ail::read_file(python_script, content))
    {
        error("Failed to load Python script \"" + python_script + "\"");
        return false;
    }

    if(prompt_mode)
        initialise_console();

    content = ail::replace_string(content, "\r", "");

    Py_Initialize();
    initialise_module();

    std::string script_directory;
    if(get_base_name(python_script, script_directory))
        PyRun_SimpleString(("import sys\nsys.path.append('" + script_directory + "')\n").c_str());

    for(int i = 0; i < string_vector.size(); i++)
    {
        string_vector[i] = ail::replace_string(string_vector[i], "\r", "");
        PyRun_SimpleString(string_vector[i].c_str());
    }

    return true;
