My package manager that installs github repos. It is meant to be used to compile and install compiled programs but it works with interpreted languages too.
If you don't own the repo that you want to add a package file to, you can add the package file to the packages repo.
git clone https://github.com/R2Boyo25/AvalonPackageManager
cd AvalonPackageManager
python3 install.py
cd ..
rm -rf AvalonPackageManagerapm install user/repo
# for my PowderSim repo
apm install r2boyo25/powdersim
# to install a local repo, just use
apm install /path/to/repo
# or
apm install .
# if you are in the repo's folder
