I'm trying to build completion control for a rather complicated command, and
have run into a snag trying to override the default precedence in the pattern
specification for extended completion (what a sentence!).

Here's what I have so far:

dbobj=(cycle cyclev device file finss gidmap history host job license location m
ediatype osref pool poolacl rack saveacl saveset slot uidmap volacl volalias vol
ume wo woparam xgid xuid)
volparams=(volid volname ansil side flipid nxtid gid uid hostid purdate cerdate
cleandate cleancnt initdate accdate mountcnt expdate length capacity slotid onda
te nxtlocid offdate cyclevid devid casel barcode mode protection brand density n
ote locid mediatypes poolid volstate statedate cycleid cyclename cycv_seq device
 flipansil flipvolname host location mediatype nxtansil nxtlocation nxtvolname p
ool prvansil prvid prvvolname rackname rackid slotname)

compctl -k '(add delete modify query)' \
   -x 'c[-1,add][-1,delete][-1,modify][-1,query]' -k dbobj - \
   'c[-2,add][-2,delete][-2,modify][-2,query] c[-1,volume] s[-] , s[-m_]' -k volparams -- sc

Unfortunately, what need to do with the second pattern set is say:

if two words ago was one of 'add delete modify, or query', and one word ago
was 'volume' and the current word starts with - or -m_, then match with any
of the volparams array.  Unfortunately, the default precedence appears to and
the c[-1,volume] and s[-] before the or'ing of s[-] , s[-m_].  Suggestions?

Also, any suggestions on cleaning this up in general would be appreciated.
This could end up being one of the longest compctl's ever built!  Which brings
up another question:  what's the max length of one of these?

You could repeat the "c[-2,...] c[-1,volume]" part after the comma.

Have you looked at the gcc compctl in Misc/compctl-examples?

How much memory do you have?

After some refinement, that line is now:

   'w[1,add][1,delete][1,modify][1,query] w[2,volume] s[-] , 
w[1,add][1,delete][1,modify][1,query] w[2,volume] s[-m_]' -k volparams -

which doesn't seem to work for the -m_ stuff.  I was just hoping that there
was an easier way of handling this, since this is just the first one for the
array.

dbobj=(cycle cyclev device file finss gidmap history host job license location 
m
ediatype osref pool poolacl rack saveacl saveset slot uidmap volacl volalias 
vol

Yes, I have, and I still stand by my statement.  This program was originally
written by some VMS people who converted it to UNIX, thus it's quite verbose
in its options.

Thanks for the help.  Any ideas why the -m_ doesn't work?  Maybe because the
previous s[-] is a prefix of [-m_] ?  Workarounds?

Yes.  Put the -m_ one first.
