If you're OK with installing third party binary dependencies, then for ripgrep, just download the deb: https://github.com/BurntSushi/ripgrep/releases … (This is pretty much what you sign up for when you use Debian. If you want bleeding edge or a more liberal packaging policy, use a different distro.)
That's why I said, "a more liberal packaging policy." Archlinux has ripgrep in its repos because it has considerably less strict policies on packaging.
