add: python cosmopolitan

[metaist]

Something to consider for a truly download-run-anywhere solution.

Packaging all of python seems a bit overkill, but it's a simple approach. Problem is, I can't get any cosmopolitan binaries to run anymore.

For example, getting the most recent datasette:

wget https://github.com/ahgamut/superconfigure/releases/download/z0.0.49/datasette.zip
chmod +x datasette.zip
./datasette.zip -V
# => invalid file (bad magic number): Exec format error

Submitted an issue: ahgamut/superconfigure#50
Going to assume this is a dead-end for now. Will reopen if it turns out to be a serious possibility.

So it turns out that the APE is inside the first level of zip file. datasette takes about 38 MB when that first layer is unzipped. Two questions:

1. How do you add your own files?
2. Can we make ds run immediately instead of running the python REPL?

wget -O ds https://cosmo.zip/pub/cosmos/bin/python
chmod +x ds # make executable
mkdir -p Lib/site-packages # create structure
cp ../src/ds Lib/site-packages # copy to structure
zip -qr ./ds ./Lib # added

wget -N https://github.com/metaist/ds/releases/latest/download/ds
chmod +x ds
sudo install ds /usr/bin

This seems to work. Now the trick is to prune the file size down a bit. I wonder how much of python I actually need.

Maybe I could do some analysis of all the python modules I use and their full set of dependencies.

Or I could start with some low-hanging fruit: probably don't need pip which comes with rich.
