create: ssh git@gitern.com gitern-create <path>
delete: ssh git@gitern.com gitern-delete <path>
list: ssh git@gitern.com gitern-list [<path>]
pubkey add: ssh git@gitern.com gitern-pubkey-add <account> (pubkey on stdin)
pubkey remove: ssh git@gitern.com gitern-pubkey-remove <SHA256 fingerprint> <account>
pubkey list: ssh git@gitern.com gitern-pubkey-list
Edit: Eventually the cli will provide a lot more (and self document what's available) so I do recommend using it, but you can happily get along with these "raw" commands for now.
This reminds me, as I suppose you expect, of a lovely ssh-based chat service i saw on here a while back: https://news.ycombinator.com/item?id=8743374
Re: ssh-based chat. I found that post very very early on while exploring gitern as just an idea! Very formative of gitern.
Interesting prior art and maybe some stealable concepts :D
When I looked at the CLI source I almost walked away. 112MB spread across 12k files from a developer I don't know is _way_ too scary to trust with access to my SSH private keys. Being able to manage it without that CLI tool, though, makes it something I might try out.
