Yesterday, for reasons best left unstated, I invented a technique for combining #bash and #Python into a single file.
The motivation was to have something a bit more powerful than the #! to decide which installed Python to use.
The magic is in line two:
#!/bin/bash
""""true"
# bash sees this, python ignores it
if [ -e /path/to/file ]; then
exec python3 "$0" "$@"
else
echo "OMG, something is missing"
exit 1
fi
"""
# begin python fun!
from thing import python_stuff
python_stuff()
PS: I believe the trailing quotation mark in `true"` is a typo, as that breaks the entire shebonk?
Because it's link a shebang, only weird!
I've added shebonk support to my forked zipapp.py, will be using to build even more portable pagekite.py bundles than before!
I wonder if this hurts my chances of getting my enhanced #zipapp merged back into upstream #CPython? :-P
... I shared this good fun with my local hackerspace Signal group, and one of the members responded with examples of TCL hackers pulling similar stunts.
He then followed up with the ultimate culmination of this kind of silliness: Actually Portable Executables https://justine.lol/ape.html
Amazing. :-D
