We actually need the implicit shell-splitting here. fetch "$ruby/$file" "$package_manager" will read the dependencies.txt file and return the apt: pkg1 pkg2 ... line that matches the "$package_manager", but without the apt: prefix. It is then implicitly splatted into an Array of individual package names. Reading each line would cause ruby_dependencies to become a singleton Array that contains the whole line (ex: ("pkg1 pkg2 pkg3")).

Hmm, agree. I just followed (blindly) what Shellcheck WIKI was proposing :D

I'm not a Arch user so I can't verify this, can you double check if pacman -T outputs the missing packages one per-line or a single-line with the package names separated by spaces?

Don't have Arch installed, either. I'm just maintaining Gentoo ebuild in ::guru overlay, and currently I simply disable make check :D

Wait, I forgot I can check using the archlinux docker image.
