Bat is a simple "package manager" that installs aur packages using git and makepkg, only supports installing.
Example usage:
python3 main.py install neofetch-git
Or if you already have Bat installed:
bat install neofetch-git
Installation:
makepkg -sri
Or with make:
sudo/doas make install
It first git clones the aur package's git url to ~/bat/{package}
Then it cd's into the directory
And then it runs makepkg -sri, and you're done!
