[C++-sig] built-in submodule creation (original) (raw)

Greetings,

I am trying to create built-in sub modules.. I have read everything I can on this subject.. And I've tried many many possible solutions.. And lost many hours actually (blech).

Some of the e-mails in these newsgroups from long ago are quite misleading.. Other e-mails on this topic seem to be inaccessible. Much of "piper-mail" is gone it seems, or relocated beyond the reach of google. (didn't know that was still possible!)

The only solution that works so far:

given that I've created dD_script and dD_object and dD* modules previously..

    object dD = object(handle<>(PyImport_AddModule ("dD")));
    char *statement =

// import what I need, I guess I don't need types actually "import sys, types\n"\

// this is importing all of the modules that I've already created.. "import dD, dD_script, dD_object, dD_types, dD_ui, dD_device, dD_render, dD_internal\n"\

// this is assigning them to the parent "package" "dD.Script = sys.modules['dD.Script'] = dD_script\n"
"dD.Object = sys.modules['dD.Object'] = dD_object\n"
"dD.Types = sys.modules['dD.Types'] = dD_types\n"
"dD.UI = sys.modules['dD.UI'] = dD_ui\n"
"dD.Device = sys.modules['dD.Device'] = dD_device\n"
"dD.Render = sys.modules['dD.Render'] = dD_render\n"
"dD.Internal = sys.modules['dD.Internal'] = dD_internal"
;

    exec(statement, mainDict, mainDict);

The non-solutions that don't work: object dD = object(handle<>(PyImport_AddModule ("dD")));

    dD.attr("Script") = handle<>(PyImport_ImportModule("dD_script"));
    dD.attr("Object") = handle<>(PyImport_ImportModule("dD_object"));
    dD.attr("Types") = handle<>(PyImport_ImportModule("dD_types"));
    dD.attr("UI") = handle<>(PyImport_ImportModule("dD_ui"));
    dD.attr("Device") = handle<>(PyImport_ImportModule("dD_device"));
    dD.attr("Render") = handle<>(PyImport_ImportModule("dD_render"));
    dD.attr("Internal") =

handle<>(PyImport_ImportModule("dD_internal"));

I also tried manipulating the dictionary of the dD module instead of attributes above

    object sys = import("sys");
    dict sysDict (sys.attr("__dict__"));
    sysDict["dD.Script"] = dD["Script"];
    sysDict["dD.Object"] = dD["Object"];
    sysDict["dD.Types"] = dD["Types"];
    sysDict["dD.UI"] = dD["UI"];
    sysDict["dD.Device"] = dD["Device"];
    sysDict["dD.Render"] = dD["Render"];
    sysDict["dD.Internal"] = dD["Internal"];

well if dD is the object these direct [] indexes fail, if it is a dict, the solution still doesn't work

    dict sysModules (sys.attr("modules"));
    sysModules["dD.Script"] = dD.attr("Script");
    sysModules["dD.Object"] = dD.attr("Object");
    sysModules["dD.Types"] = dD.attr("Types");
    sysModules["dD.UI"] = dD.attr("UI");
    sysModules["dD.Device"] = dD.attr("Device");
    sysModules["dD.Render"] = dD.attr("Render");
    sysModules["dD.Internal"] = dD.attr("Internal");

if I do dict stuff instead of attribute, still doesn't work..

===================

Is there a better way for me to do this, than executing the python code segment? Does anyone know what is going on behind the scenes in the python code execution?

Thanks,
