Topics

ssh_config hosts

A lot of these have to do with hosts defined in the ~/.ssh/config and /etc/ssh_config files not showing up as options for completion. Zsh's own _ssh completion definition has code that reads hosts from ~/.ssh/config, so it seems like they intend for it to be there by default. But it's not showing up for a lot of people, me included. We need to figure this out, to avoid thrashing on this topic.

You can check #4162 and #2707

#4162 and #2707 look like they're still open (though #4162 has an associated PR merged). I'd rather wait until they get closed out before checking them off.

Sorry I meant #4162 (now closed) and #3321 instead of #2707

Both are now closed :)

One of the reasons hosts do not show up is known_hosts - if you delete it, a lot more hosts will be shown for config - i guess the keyword search is limited to a specific number of hits and probably parses known_hosts first, now showing the ssh/config ones at all
