ssh completion problem

ssh completion problem

[Bart Schaefer]

This has been bugging me for a while ... I mentioned it once before, but
Sven at that time said he couldn't reproduce it.  I've just finally got
around to doing a bit more digging.

The symptom is that, even though I have a `users-hosts' style (real account
names munged below to avoid email address harvesters) such as:

    zstyle ':completion:*:(ssh|scp):*:my-accounts' users-hosts \
       lll@bbb.com zzz@iii.com sss@zzz.com

when I complete after `lll@' I get offered all possible hosts from the
`hosts' style.  I want to be offered only `bbb.com' in that case.

(When I complete after just `l', it completes to `lll', then waits for
another tab.)

The problem is somehow related to this additional style:

    zstyle ':completion:*:ssh:*' tag-order my-accounts \
       'hosts:-host hosts:-domain:domain hosts:-ipaddr:IP\ address *'

If I take that out, the completion works as I expect in this case, but
of course then I don't get the separation of hosts into host, domain,
and ipaddr groups in other cases.

I'm sure I'm missing some obvious reason why the my-accounts tag can't
be used in the tag-order style.  It seems to work for the user part of
the completion, though; just not for the host part.  What's up?

The my-accounts tag is only used when _combination looks up the
users-hosts style and not ever with _tags (users, hosts etc are used
there) so it can't be used with tag-order.

There are a number of things about _combination that I'm not entirely
happy with. I have ideas and some semi-working code that I'll hopefully
get around to finishing sometime.

I'll pass on the main part of your question until I've had a chance to
play with a running zsh.

That's exactly one of the things that was bothering me. I just complete
from an arbitrary list as so (using your example accounts):

_ssh_acounts () {
    compadd lll@bbb.com zzz@iii.com sss@zzz.com
}
compdef _ssh_accounts ssh:

It then seems to work the way I expect it to (which says nothing of the
correctness :))
