No packages completion for zypper

[rominf]

As I understood (I've read zypper.fish completions file), fish should complete packages for me. It doesn't work. After pressing TAB key I instantly get files completions.

fish, version 2.1.1
openSUSE 13.1, 13.2

The package list is generated by RPM, which takes a long time, so the output is cached. It won't be available on the first run. Once it's generated, you should have a file at ~/.cache/.rpm-cache.$USER, and fish will complete packages from this cache.

If it's not generating or using the cache correctly, please reopen the ticket.

By some reason file was empty. I deleted it and launched a new fish session to regenerate it. I've pressed TAB and nothing happened. I've copied a line, generated cache file and completion started to work.

rpm command knows only about installed packages. How about using zypper on openSUSE?

# all packages
zypper --quiet --no-refresh search  | tail -n +4 | sed -E 's/^. \| ((\w|[-_.])+).*/\1/g' >/tmp/packages
# installed only
zypper --quiet --no-refresh search --installed-only  | tail -n +4 | sed -E 's/^. \| ((\w|[-_.])+).*/\1/g' >/tmp/packages
# uninstalled only
zypper --quiet --no-refresh search --uninstalled-only  | tail -n +4 | sed -E 's/^. \| ((\w|[-_.])+).*/\1/g' >/tmp/packages
