MarsSeed [1] filed a deletion request for htmlcompressor [2]: Abandoned package from 2016 from a long-discontinued code.google.com project. Broken since at least Dec 2016 as per comment. But last comment is from 2018 (again about being broken). It's best to delete it at this point. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/htmlcompressor/
