Hi Monks!
I have a utility which iterates over a set of OS packages and finds the Zypper repo's name (using zypper info) and then it's URI and name (using zypper repos). The code looks like:

while(my ($package) = keys(%found_packages)) {
  delete($found_packages{$package});

  # Ignore already handled packages
  next if (defined($checked_packages{$package}));
  $checked_packages{$package} = 1;

  # Find the zypper information of the OS package
  my $cmd = "$ZYPPER info $package";
  my ($stdout, $stderr, $exit_status) = capture { system($cmd); };
  if ($exit_status == 0 && $stdout =~ /^Repository\s*:\s*(\S+)\s*$/m) 
+{
    my $repository_name = $1;
    if ($repository_name eq '@System') {
      if (defined($packages_href->{$repository_name})) {
        $packages_href->{$repository_name}{'packages'}{$package}++;
      } else {
        $packages_href->{$repository_name} = {
          'packages' => {
            $package => 1
          }
        };
      }
    } else {
      if (defined($packages_href->{$repository_name})) {
        $packages_href->{$repository_name}{'packages'}{$package}++;
      } else {
        $cmd = "$ZYPPER repos -u $repository_name 2> $DEV_NULL";
        ($stdout, $stderr, $exit_status) = capture { system($cmd); };
        if ($exit_status) {
          print("Failed to find the information of the zypper reposito
+ry: $repository_name");
        } else {
          my $repository_alias = $1 if ($stdout =~ /^Alias\s*:\s*(\S+)
+\s*$/m);
          my $repository_uri = $1   if ($stdout =~ /^URI\s*:\s*(\S+)\s
+*$/m);
          if (is_empty_str($repository_alias) || is_empty_str($reposit
+ory_uri)) {
            print("Failed to find the uri or alias of the zypper repos
+itory: $repository_name");
            next;
          }
          $packages_href->{$repository_name} = {
            'alias'  => $repository_alias,
            'uri'    => $repository_uri,
            'packages' => {
              $package => 1
            }
          };
        }
      }
    }
  }
}

I noticed that the invokation of the "zyyper info" command is really slow. I also noticed that you can provide a list of packages and it will print the output for each one. For example:

$ /usr/bin/zypper info python-rpm-macros Mesa-libEGL1 libedit0 fontcon
+fig-devel

I'm trying to add the whole list of packages into the zypper info command and then iterate over each such block and extract the repository name and on each such name get the alias and URI. I'm struggling with the parsing part. Is it possible to get a suggestion on a how to parse the output of zypper info?
