awk is an external program, and it is better to stick to shell built-ins.
Also, even with external awk, sort -u is redundant, because the shell does
this on its own.
"machinectl list" only lists running machines while many of the MACHINES
commands use names of images; both running and non-running.
List machines from both "list" and "list-images" and use sort -u to
avoid duplicates.
_loginctl: respects the verbose style. which allows a user to get
the pre d5df0d950f behavior of not showing a description for sessions
and users, by default they aren't shown.
zstyle ':completion:*' verbose true
or
zstyle ':completion:*:loginctl*:*' verbose true # or similar
Will show the descriptions.
zstyle ':completion:*' verbose true
and
zstyle ':completion:*:loginctl*:*' verbose false # or similar
Won't show descriptions for loginctl only
_systemd: complete pids for systemd-notify's --pid option.
display a message of the expected argument for other options.
_systemd-inhibit: complete block & delay for --mode
display a message of the expected argument for --who/--why
filenames will be completed for --image/-i/--bind/--bind-ro/--tmpfs
network interfaces for --network-(interface|macvlan|ipvlan|bridge)
users for --user/-u, yes & no for --register, x86 * x86-64 for
--personality
display a message of the expected argument for --machine/-M/--uuid
--slice/-S/--port/-p/--selinux-*/-Z/-L/--setenv
Allow completing commands(and their options) of the host system for COMMAND
1) the iterator `fun' has an local scope. after running the completer,
it will no longer be defined.
2) use _describe instead of calling compadd. Using compadd without
calling _description or something similar before, restricts the
user's ability to customize what is presented to them.
zstyle ':completion:*' format 'Completing %d'
- now displays an header showing what is being completed.
zstyle ':completion::complete:loginctl-*::users' users user1 user2
- allows the user to manually specify which users is offered
zstyle :completion::complete:loginctl-kill-user:\* \
ignored-patterns '(100<0-4>|user1)'
- selectively ignore some users when completing loginctl kill-user
<tab>
Sessions, UIDs now have descriptions when selecting them.
3) removed the call to _loginctl_all_seats in _loginctl_attach(), since
_loginctl_seats calls it a second time, right before adding matches.
There isn't a noticeable difference doing this.
Optimize _filter_units_by_property by calling `systemctl` only once with
a list of units, and not once per unit.
I could not reproduce the "Unknown unit" error mentioned in a FIXME,
which might have made this necessary previously.
