Subject: Questions about _values
Date: Mon, 26 Jan 2009 00:36:07 +0100 [thread overview]
Message-ID: <20090125233607.GA30627@fly.srk.fer.hr> (raw)
Hello,
I'm trying to write some completions with mixed success. Currently one
of my completions looks like this:
{vsun}/# pcred <TAB pressed here
0 -- root sched
1 -- root /sbin/init
122 -- root /usr/sbin/nscd
125 -- root /usr/lib/sysevent/syseventd
134 -- daemon /usr/lib/crypto/kcfd
140 -- root /usr/lib/power/powerd
1402 2777 438 -- root /usr/lib/ssh/sshd
143 -- root /usr/lib/picl/picld
2 -- root pageout
237 -- root /usr/bin/VBoxService
238 -- root /usr/sbin/cron
2780 1405 -- dave /usr/lib/ssh/sshd
2782 1407 -- dave -zsh
...
Argument is a PID, completed with _values.
1. I tried to get the same effect with _describe, but I don't know how
to do that (value grouping if description is the same and the "--"
separator). I looked at _values source, but I don't understand how
it does what it does. I suppose compvalues does the trick somehow. How
do I produce the above output with _describe?
2. Is there a way to tell _values to limit the maximum number of items
in a group? In the above example the description (process name) is
more important than the items, so I'd like to avoid description
trimming which happens by default.
3. Is there a way to tell _values (or _describe) to sort offered
completions by description and not by item? In that case I'd get sort
by username here, which is much better than sort by PID.
Also, is there a way to tell them not to sort? The completion list
could already be sorted in a meaningful way.
4. If I keep pressing TAB, zsh will offer completions. Is there a way to
make it highlight (print the characters in bold or some color, for
example) the offered item and its description in the list?
Here the offered completions (PIDs) aren't descriptive, so the user must
associate them with the descriptions (command names) to actually select
what he wanted. It's hard to do vithout visual cue.
