building _tkinter module with .NET 2005?
I have the Python 2.5.1 source and I'm trying to build the debug version of the _tkinter module. I've got .NET 2005 (Visual Studio 8) but the instructions in the pcbuild\readme.txt file only contain instructions for using .NET 2003 (Visual Studio 7.1). There's another readme.txt file under the pcbuild8 directory, but is almost identical to the one in the pcbuild folder. (There's some information about some new instrumented build settings, but that's about it) The instructions contained in both these readme.txt files say that the Tcl, Tk, and Tix projects must be built from the command line first, using nmake.exe in conjunction with the corresponding makefile.vc for each package. I can get this to work using .NET 2003, but not with .NET 2005. Is there an updated set of instructions somewhere for doing this with .NET 2005? Is it even possible to get it to work with the newer version of .NET? -- http://mail.python.org/mailman/listinfo/python-list
integrating embedded interpreter with external controls
I need some advice about how to go about architecting a solution to the following problem. I'd like to create an application that has an interactive listener/ console window in which the user can enter commands (in much the same vain as 3D Studio Max, for those who are familiar with the product). The console would essentially be an embedded Python interpreter running the interactive loop (a call to the C API's PyRun_InteractiveLoop()). I'd also like buttons and other UI controls to be able to access functions and objects that are defined through the console. I'm not really sure how to integrate the UI controls with the console though, especially if the console is running PyRun_InteractiveLoop(), which is a tight loop. I'm guessing that the solution will most likely require the console to run in a separate thread, but I still don't know how to get the UI to interact with the console. Does anyone have any helpful suggestions? -- http://mail.python.org/mailman/listinfo/python-list
multi-line input?
I'm writing a C++ application with an embedded Python interpreter.
Command text is captured and passed to the interpreter a single line
at a time. My question is this: is there a simple way of determining
whether a given input line of text will cause the prompt to change
from the regular ">>>" to the multi-line "..." before sending the text
to the interpreter? I suppose the completely correct solution would be
tokenize and parse the entire string and then examine all the
constituent parts, but that seems like a lot more work than I really
want to do.
As far as I can tell, there are only a few ways to trigger the multi-
line input prompt:
- if-statement, for-loop, function or class definition
- line continuation (\)
- block quote (""" or ''')
Any help would be greatly appreciated.

Re: multi-line input?
Ah, thanks. Using the information you provided, I found the following page: http://archives.free.net.ph/message/2303.091004.4da616bf.en.html It's not perfect, but it's close enough for what I need. -- http://mail.python.org/mailman/listinfo/python-list
newbie question: retrieving values of variables through C API
I've got an application that embeds the Python interpreter. I have the
following command in my code:
PyRun_SimpleString("a = \"hello\"");
My question is, what is the C API function call for retrieving the
value of the variable "a"?

unhandled exception question
I'm working on a test application that embeds the Python interpreter.
I have the following problem...
I've created my own interactive interpreter loop. Essentially, it
reads the command from the prompt and calls the following C code:
PyObject* pMainModule = PyImport_AddModule("__main__");
PyObject* pMainDictionary = PyModule_GetDict(pMainModule);
PyObject* pObj = PyRun_String(pCommandText, Py_single_input,
pMainDictionary, pMainDictionary);
where pCommandText is the text entered by the user.
I also have the following Python functions defined:
def Boo():
raise Exception()
def Foo():
try:
MyModule.SomeFunction()
except Exception:
print "goodbye"
MyModule.SomeFunction() is defined in C. All it does is call Boo()
with the following code:
PyObject* pMainModule = PyImport_AddModule("__main__");
PyObject* pMainDictionary = PyModule_GetDict(pMainModule);
PyObject* pObj = PyRun_String("Boo()", Py_single_input,
pMainDictionary, pMainDictionary);
If it's at all relevent, I'm using Boost.Python to embed MyModule.
Now here's the problem: when I type "Foo()" at the prompt, it calls
Foo(), which calls MyModule.SomeFunction(), which calls Boo(), which
raises the exception. However, the exception doesn't get handled,
despite the try-except statement in Foo(). Even stranger, if I
manually enter the entire multi-line try-except statement at the
prompt (instead of simply calling Foo()), the exception is handled
properly and "goodbye" is printed to the screen.
What's going on here? Why is exception properly handled in the second
case, but not the first?

help building debug .pyd files
The installation of Python 2.5 comes with a bunch of built-in extension modules (.pyd files) under the DLLs directory. I've downloaded the Python source code and am trying to build the debug versions of all of these files. However, some of the projects won't build because they are looking for header files that don't exist anywhere. Specifically, the non-building projects are: _bsddb _sqlite3 _ssl _tkinter bz2 Additionally, the project for the _hashlib module seems to be entirely missing from the Python source. Any idea where I can find it? Is there a set of pre-built debug versions of all of these modules I can download somewhere? It would save me a lot of time trying to figure out where all these missing files are supposed to come from... -- http://mail.python.org/mailman/listinfo/python-list
