Bundling Apps

To bundle your app in an .mpk file, just make an uncompressed "zip" file of it, without including the top-level com.micropythonos.helloworld/ folder.

It's recommended to make the .mpk file deterministic by: - setting the file timestamps to a fixed value - sorting the files, so the order is fixed - excluding extra file attributes and directories

For example:

cd com.micropythonos.helloworld/
find . -type f -exec touch -t 202501010000.00 {} \; # set fixed timestamp
find . -type f | sort | TZ=CET zip -X -r -0 /tmp/com.micropythonos.helloworld_0.0.2.mpk -@ # sort, -Xclude extra attributes, -recurse into directories and -0 compression

Take a look at scripts/bundleapps.sh to see how the MicroPythonOS default apps are bundled.
