Okay. Here's my "Hello World" script.
<CONSOLE>
J:\ >dir helloworld.py
Volume in drive J is EUGSRV340
Volume Serial Number is 0435-C18F
Directory of J:\
03/02/2007 03:20 PM 43 helloworld.py
1 File(s) 43 bytes
0 Dir(s) 23,540,051,968 bytes free
J:\ >type helloworld.py
#!/usr/bin/python2.3
print "Hello World"
J:\ >helloworld.py
Hello World
J:\ >
</CONSOLE>
This script will run on a Windows XP box with the Python interpreter
installed. At 43 bytes, it's not too bad. Running on a box without
Python is a different story. I can make a .exe file using py2exe:
<CONSOLE>
J:\ >type setup.py
# setup.py
from distutils.core import setup
import py2exe
setup(
zipfile=None, # append zip-archive to the executable.
options = {"py2exe": {"compressed": 1,
"optimize": 2,
"ascii": 1, # to make a smaller executable,
# don't include the encodings
"packages": ["xml.sax.drivers",
"xml.sax.drivers2",],
}
},
console=["helloworld.py"]
)
J:\ >python setup.py py2exe
<<py2exe output snipped>>
J:\ >cd dist
J:\dist >dir *.exe
Volume in drive J is EUGSRV340
Volume Serial Number is 0435-C18F
Directory of J:\dist
03/02/2007 03:39 PM 493,826 helloworld.exe
05/11/2005 07:03 PM 16,384 w9xpopen.exe
2 File(s) 510,210 bytes
0 Dir(s) 23,504,711,680 bytes free
J:\dist >helloworld
Hello World
J:\dist >
</CONSOLE>
I'm a novice at py2exe. There are probably ways to tweak the setup file
to make the .exe file smaller.
I wonder if Kirk's 263 byte Forth program is self-contained?
