Creating/Editing AUR packages with docker

# This enables using GUI as well for testing
docker run -it --rm --net=host -e DISPLAY -v /tmp/.X11-unix archlinux bash

# System Setup
pacman -Sy
# You might need to install upgrades too
pacman -Su --noconfirm
# (Add required build packages as needed)
pacman -S --noconfirm git base-devel fakeroot vim openssh namcap xorg-xauth cmake qt5-base

# Set up a user if using docker
useradd -m foo
su foo
cat <<HERE >key
# (KEY)
chmod 600 key

# Clone AUR package
GIT_SSH_COMMAND="ssh -o StrictHostKeyChecking=no -i $AUR_SSH_KEY" git clone ssh://aur@aur.archlinux.org/$PACK_NAME.git

# Edit script see https://wiki.archlinux.org/index.php/Creating_packages
makepkg -f

# Test
pacman -U *.pkg.tar.zst
namcap *.pkg.tar.zst

# Set up GUI for docker
touch ~/.Xauthority
# Run `xauth list` on the host and paster the output as argument to the following
xauth add

# Submit to AUR
makepkg --printsrcinfo > .SRCINFO
git config --global user.name
git config --global user.email
git commit
GIT_SSH_COMMAND="ssh -o StrictHostKeyChecking=no -i $AUR_SSH_KEY" git push origin master

Run a VM from an ISO file to test in a full DE

# Append the path to the iso file
qemu-system-x86_64 -m 4G -boot d -enable-kvm -smp 3 -net nic -net user -cdrom
