Hint: /var/cache/zypp/raw/* contains gzipped xml/sqlite files which probably already contain the needed list of available packages. So we "just" need a parser.
No. /var/cache/zypp/raw/ contains all the raw metadata for all (even disabled) repos. And you don't want to fiddle with all the supported repo formats and thair parsers. Upon refresh zypp will parse the repos and build solv caches in /var/cache/zypp/solv. At least a common format for all repos, e.g. installed: dumpsolv /var/cache/zypp/solv/\@System/solv but you'd still need to filter out the disabled repos. --- What about: zypper -x --no-refresh se for package names zypper -x --no-refresh se -s for package names, version, and arch zypper+XML is probably too slow..... Maybe a small zypper-complete binary taking a stem and writing the possible completions to stdout. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

zypper+XML is probably too slow..... Just did a test and XML-dump zypper's packages. It takes approx 2 second (28550 available packages on my Xeon L5506 @ 2.13GHz)
time zypper -x --no-refresh se > /dev/null real 0m2.218s user 0m1.971s sys 0m0.159s Extracting package names with grep increases duration by about 0.4 sec. # time zypper -x --no-refresh se | grep -o -P '(?<=name\=\").*(?=\" summary)' > /dev/null real 0m2.565s user 0m2.450s sys 0m0.156s And even it's slow on the first try, it's better having it slow than not having it at all. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It's a quick hack we use when investigating solver testcases. But it has little overhead and it basically does what we need: Usage: NameReqPrv [--root ROOTDIR] [OPTIONS] NAME... [[OPTIONS] NAME...]... Load all enabled repositories (no refresh) and search for occurrences of NAME (regex) in package names, provides or requires. --root Load repos from the system located below ROOTDIR. If ROOTDIR denotes a sover testcase, the testcase is loaded. --installed Process installed packages only. -i/-I turn on/off case insensitive search (default on) -n/-N turn on/off looking for names (default on) -p/-P turn on/off looking for provides (default off) -r/-R turn on/off looking for requires (default off) -c/-C turn on/off looking for conflicts (default off) -o/-O turn on/off looking for obsoletes (default off) -m/-M turn on/off looking for recommends (default off) -s/-S turn on/off looking for supplements (default off) -a short for -n -p -r -A short for -n -P -R -D <pkg> dump dependencies of <pkg> It supports --root and --installed (up/rm); per default searches case insensitive for package names matching a regexp and prints the result in a pretty ugly format. zypp-NameReqPrv '^zypp' The 270 lines of code could easily serve as template for a zypp-complete command, producing more suitable output. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Maybe it is an option to use the search algorithm already included in zypper.
For example zypper -x --no-refresh se ema* Great idea. I tried this and it's IMHO sufficiently fast.
@Micheal: I created a pull-request in the official zypper repo at github. I wonder if you want to review and merge it. (In reply to comment #7)
If you're using a recent libzypp, the `zypp-NameReqPrv` command might already be available on your systems. I also tried this one and its indeed much faster than a "zypper se". However, at the moment I lack of sufficient understanding of libzypp to rewrite zypp-NameReqPrv to a zypp-complete.

Great. I'll have a look at it.

I'll take that part. I don't know in depth how the bash completion works, but with your patch I'll be able to provide a dedicated command to speed up the cases. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
