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: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' => { $package => 1 } }; } } } } }
I'm trying to add the whole list of packages into the zypper info command and then iterate over each such block and extract the repository name and on each such name get the alias and URI. I'm struggling with the parsing part. Is it possible to get a suggestion on a how to parse the output of zypper info?$ /usr/bin/zypper info python-rpm-macros Mesa-libEGL1 libedit0 fontcon +fig-devel Loading repository data...
