Why Tcl/Tk?
I'm a little curious, why does most scripting languges(i.e. python and ruby) use Tcl/Tk rather than wx or Fox as its standard GUI? Although I did notice that the Vpython IDE that uses Tkinker starts up a lot faster than the DrPython IDE that uses wxpython. But that makes no sense, Tk is based on Tcl, a scripting language, but wx is written in C++. __ Do You Yahoo!? Tired of spam? Yahoo!

functions without parentheses
Hi,
Is it possible to create a function that you can use
without parenthesizing the arguments? for example, for
def examine(str):
.
.
Is there some way to define it so that I can call it
like
examine "string"
instead of examine("string")?
thanks in advance

installing SWIG for python
Hi, I just installed SWIG on Windows(Cygwin) and tried to use it to compile some of the example python programs. For the first two commands it produced no error swig -python example.i gcc -c example.c example_wrap.c -I \ /usr/include/python2.4 For the third one however ld -shared example.o example_wrap.o -o _example.so It gave me a long list of errors listed at the end of this email. The error messages were rather baffling because the C file that was to be made into a python Module was a simple gcd function, it doesn't need strlen, or any of the other C functions, and much less Tcl_Append, what does this have to do with Tcl? Any help or suggestions on this would be appreciated... -Jerry example_wrap.o:example_wrap.c:(.text+0x1cb3): undefined reference to `strlen' example_wrap.o:example_wrap.c:(.text+0x1ccf): undefined reference to `strchr' example_wrap.o:example_wrap.c:(.text+0x1cf7): undefined reference to `strstr' example_wrap.o:example_wrap.c:(.text+0x1d5d): undefined reference to `Tcl_Append Element' example_wrap.o:example_wrap.c:(.text+0x1e09): undefined reference to `Tcl_SetRes ult' example_wrap.o:example_wrap.c:(.text+0x1e40): undefined reference to `Tcl_GetStr ingFromObj' example_wrap.o:example_wrap.c:(.text+0x1e56): undefined reference to `strcmp' example_wrap.o:example_wrap.c:(.text+0x1e80): undefined reference to `strcmp' example_wrap.o:example_wrap.c:(.text+0x1ec6): undefined reference to `Tcl_GetStr ingFromObj' example_wrap.o:example_wrap.c:(.text+0x1edc): undefined reference to `strcmp' example_wrap.o:example_wrap.c:(.text+0x1f48): undefined reference to `Tcl_GetObj Result' example_wrap.o:example_wrap.c:(.text+0x1f50): undefined reference to `Tcl_Duplic ateObj' example_wrap.o:example_wrap.c:(.text+0x1f70): undefined reference to `Tcl_GetStr Start your day with Yahoo! - make it your home page http://www.yahoo.com/r/hs -- http://mail.python.org/mailman/listinfo/python-list

SWIG again
Robert Kern
>Write a distutils setup.py script to do all of the
>compiling and linking.
Ok, I wrote the following distutils setup.py script
from distutils.core import setup, Extension
setup (name = 'example',
version = '2.4',
ext_modules = [Extension('example', \ ['example.c',
'example_wrap.c'])] )
I put it in the same directory as the extension files
and I ran from the command line
python setup.py install,
and nothing happened...
Someone help me!!

distutils on Win32 using .NET Framework SDK
Hi, I was trying to build a C++ extension on Win32 with distutils. The extension worked on Cygwin but when I tried it with the Win32-build python, it complained that I don't have .NET Framework SDK installed. But after I installed .NET Framework SDK 2.0, it still complains "error: The .NET Framework SDK needs to be installed before building extensions for Python." (I also did try restarting my computer) Does anyone know how to make the .NET Framework SDK visible to Python? thanks in advance, -Jerry __ Do You Yahoo!? Tired of spam? Yahoo!
