pkg list-installed --manual

Please add a simple API to list manually-installed packs, if possible

[sylirre]

apt-mark showmanual

Pay attention that bootstrap packages are always shown as manually installed. You will have a slightly larger list of manually installed packages than expected.

Thank you for the info! I tried searching for this everywhere, but found stuff that only worked for Debian-based distros
