Moin moin!

Jippie - it works with zypp from svn. So just one more question: can i somehow only query * packagename * version * repoalias or do i need to extract this. I mean e.g. for item in pool: item.name() item.version() item.repoalias() Best regards Jan-Simon -- To unsubscribe, e-mail: zypp-devel+unsubscribe@opensuse.org For additional commands, e-mail: zypp-devel+help@opensuse.org

nope.. that would be shame for libzypp :O) This 'item' is probably a zypp::ui::Selectable (don't know what's the Python way of saying this), right? then 'item.name()' should work.

item.version()

This is a bit more complex: Resolvable::edition() is what you want, but a Selectable is a group of all available packages (well.. resolvables) with the same name and kind. Look at the Selectable interface to see what functions are there to get the Resolvables: available{Begin,End} - gets all of Selectable's Resolvables (as PoolItems!) installed{Begin,End} - gets only the installed ones theObj - gets the object with newest version and best architecture among the available objects candidateObj - the same as theObj :O) installedObj - the first of the installed objects a PoolItem contains ResStatus and a Resolvable, a Resolvable is a Package, Patch, Pattern, or Product (look at the doxygen docs, or c++ header docs).

item.repoalias()

Each Resolvable contains a reference to the Repository of origin and the associated RepoInfo object. You get the alias from that one. HTH, jano -- To unsubscribe, e-mail: zypp-devel+unsubscribe@opensuse.org For additional commands, e-mail: zypp-devel+help@opensuse.org

[...] I couldn't sleep, so i looked at some snippets in satsolver-bindings. What works now is this (don't blame me, I'm learning ;) ): (all in python-bindings) Import the remote repo with libzypp. Load the solv file with satsolver. Get the values i want. It looks like this: import zypp import satsolver zy = zypp.ZYppFactory_instance().getZYpp() mytemppath = zypp.Pathname( "/tmp/a" ) zy.initializeTarget( mytemppath ) myrepoinfo = zypp.RepoInfo() myrepoinfo.addBaseUrl( zypp.Url( "http://localhost/software/base_factory" )) # local obs instance output myrepoinfo.setAlias( "software" ) myrepoinfo.setEnabled( True ) myrepoinfo.setType( zypp.RepoType.RPMMD ) myrepoinfo.setGpgCheck( False ) # not yet implemented . i would need this atm : ZYPP_KEYRING_DEFAULT_ACCEPT_ALL=1 myrepomanageroptions = zypp.RepoManagerOptions( mytemppath ) myrepomanager = zypp.RepoManager( myrepomanageroptions ) myrepomanager.addRepository( myrepoinfo ) myrepomanager.refreshMetadata( myrepoinfo ) myrepomanager.buildCache( myrepoinfo ) myrepomanager.loadFromCache( myrepoinfo ) for item in pool: print item.string() # e.g. U__s_(213)cairo-doc-1.4.14-20.2.i586(software) print item # e.g. > # i had no idea how to proceed from here /me blind watching doxygen pages and stuff like ^^^^^ # then i looked at satsolver and discovered /tmp/a/var/cache/zypp/solv/software/solv # so if someone could show me how to do this with libzypp - he would be my hero of the day ;) mysatpool = satsolver.Pool() tmprepo = mysatpool.add_solv("/tmp/a/var/cache/zypp/solv/software/solv") tmprepo.set_name("myhackrepo") mysatpool.prepare() for solv in mysatpool: print solv print "Name : "+str(solv.name()) print "Version : "+str(solv.evr()) print "Group : "+str(solv.attr("solvable:group")) print "Summary : "+str(solv.attr("solvable:summary")) print "Description:" print solv.attr("solvable:description") # These are the values I wanna use atm.

PoolItem combines Solvable and Status: Right ... which is good ;)

item.resolvable() // Type zypp::ResObject_Ptr

item.resolvable().name() item.resolvable().edition() .arch() .provides() .summary() .description() .repoInfo() ...

But i need "Group" which is not available by this.

(see ResObject and Resolvable) This is how it should work, but currently the bindings are messed up again. ;( I can't check if it realy does. I'll do :D.

Could it be zypp/sat/ is missing in the bindings ? std::string zypp::sat::Solvable::lookupStrAttribute( const SolvAttr & attr ) const would give me access to the other values, right ? Thanks!

(see ResObject and Resolvable)

ResObject is the base class providing attributes common to Package, Pattern, Patch and Product. You can use e.g zypp.isKindPackage( item ) to test whether some item is a Package. And zypp.asKindPackage( item ) to return the corresponding Package that gives access to all Package attributes: ( This requires libzypp / libzypp-binding from SVN revision 10956 ) +------------------------------------------------------------------+ #! /usr/bin/python import zypp Z = zypp.ZYppFactory_instance().getZYpp() Z.initializeTarget( zypp.Pathname("/") ) Z.target().load(); repoManager = zypp.RepoManager() repos = repoManager.knownRepositories() for repo in repos: if not repo.enabled(): continue if not repoManager.isCached( repo ): repoManager.buildCache( repo ) repoManager.loadFromCache( repo ); print "Items: %d" % ( Z.pool().size() ) for item in Z.pool(): if item.status().isInstalled(): t = "i" else: t = "*" print "%s %s:%s-%s.%s\t(%s)" % ( t, item.kind(), item.name(), item.edition(), item.arch(), item.repoInfo().alias() ) if zypp.isKindPackage( item ): print " Group: %s" %(zypp.asKindPackage( item ).group( ) ) +------------------------------------------------------------------+ -- cu, Michael Andres +------------------------------------------------------------------+ Key fingerprint = 2DFA 5D73 18B1 E7EF A862 27AC 3FB8 9E3A 27C6 B0E4 +------------------------------------------------------------------+ Michael Andres YaST Development ma@novell.com SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nuernberg) Maxfeldstrasse 5, D-90409 Nuernberg, Germany, ++49 (0)911 - 740 53-0 +------------------------------------------------------------------+ -- To unsubscribe, e-mail: zypp-devel+unsubscribe@opensuse.org For additional commands, e-mail: zypp-devel+help@opensuse.org
