Some time ago on #artix IRC channel popped up a question on how to get the installed size of all packages in given repository and I together with other people on the channel created a one liner in shell to do exactly that. But before I have to mention that Pacman prints the “Installed size” value when we try to install packages. So one way is to try to install all packages but this can also include dependencies and may require some pacman magic which I am not aware of. I forgot to mention, this method may require root access or sudo privileges which is not good enough for me.
