Python zip exe
Package python main script and module dependencies into a single executable
This takes your Python application and packages it into a single executable shell script. You application can be made of up multiple python scripts. The executable shell script is also compressed, so the resulting script is smaller than the original. This should work on any system that has Python and a Bourne shell (works on Cygwin too).
Note that this does not package the Python interpreter into the executable. This packages only you python code into a zip file, but this still allows you to distribute your application as a single shell script that will run on any system with Python installed.
First you need to zip all your python files:
zip main.zip main.py spam.py eggs.py
You must use zip compress. It won't work with gzip or bzip2. Oh well, zip still has pretty decent compression.
In theory, you could zip the .pyc files, but the byte code is guaranteed to run only on exactly the same version Python interpreter (including minor version). It is safer to just package the .py files.
A plain text header "zipheader.sh" script:
#!/bin/sh # This is a self-extracting executable. # Execute this like any normal executable. # You may need to "chmod a+x" this file. # This is a binary ZIP file with a Python loader header. # # Bourne shell loader: PYTHON=$(which python 2>/dev/null) if [ ! -x "$PYTHON" ] ; then echo "Python not found!" exit 1 fi exec $PYTHON -c " # Python loader: import sys, os if int(sys.version)<2: print 'Python version 2.3 final or greater is required.' print 'Your version is', sys.version os._exit(1) major = sys.version_info minor = sys.version_info releaselevel = sys.version_info if (major==2 and minor<3) or (major==2 and minor==3 and releaselevel!='final'): print 'Python version 2.3 final or greater is required.' print 'Your version is', sys.version os._exit(1) sys.path.insert(0, sys.argv) del sys.argv[0:1] import main main.main() " $0 $@ # Zip file:
Concatinate zipheader.sh with the zip file.
cat zipheader.sh main.zip > main
Set main as executable.
chmod +x main
This is an improvement on Joerg Raedler's Python recipe, 215301. The original closes stdin. The herefile in the shell script redirects stdin before python gets a chance to start. This disables raw_input() and anything else that reads sys.stdin. Unfortunately, Raedler's boot script closes stdin, which is a fairly big limitation. The herefile in the shell script (END_OF_PYTHON_CODE) redirects stdin before python starts; stdin is closed at the end of the herefile. This disables raw_input() and anything else that reads sys.stdin.
