Sad to see Joe orphaned, this is pretty much my most-used application for text editing. For those of us who grew up with Wordstar, it’s such a great command-line tool that hits that middle-ground between Vim and other more “comprehensive” editors.
I’m assuming a lack of maintainer won’t automatically result it in being purged from the AUR.
Since it was just created yesterday, I am guessing this was dropped to AUR from the repos. In this case, there is a high likelihood someone will adopt it.
EDIT: The commit message from yesterday is “Dropped from the repos” so I suppose it isn’t a guess anymore.
