revisorの代わりその3

cli.pyのこれがすべて。

   def deplist(self, args):
       """cli wrapper method for findDeps method takes a list of packages and
           returns a formatted deplist for that package"""

       self.doRepoSetup()


       for arg in args:
           pkgs = []
           ematch, match, umatch = self.pkgSack.matchPackageNames([arg])
           for po in ematch + match:
               pkgs.append(po)

           results = self.findDeps(pkgs)
           self.depListOutput(results)

       return 0, []

pkgsとresultが何であるかが問題。で、resultはdepListOutをみてやればいい。

output.pyでこんな感じになっている。

    def depListOutput(self, results):
        """take a list of findDeps results and 'pretty print' the output"""

        for pkg in results.keys():
            print "package: %s" % pkg.compactPrint()
            if len(results[pkg].keys()) == 0:
                print "  No dependencies for this package"
                continue

            for req in results[pkg].keys():
                reqlist = results[pkg][req]
                print "  dependency: %s" % prco_tuple_to_string(req)
                if not reqlist:
                    print "   Unsatisfied dependency"
                    continue

                for po in reqlist:
                    print "   provider: %s" % po.compactPrint()

んで、site-package/yum/__init__.pyの中で

    def findDeps(self, pkgs):
        """Return the dependencies for a given package object list, as well
           possible solutions for those dependencies.

        results = {}
        self.doRepoSetup()

        for pkg in pkgs:
            results[pkg] = {}
            reqs = pkg.requires
            reqs.sort()
            pkgresults = results[pkg] # shorthand so we don't have to do the
                                      # double bracket thing

            for req in reqs:
                (r,f,v) = req
                if r.startswith('rpmlib('):
                    continue

                satisfiers = []

                for po in self.whatProvides(r, f, v):
                    satisfiers.append(po)

                pkgresults[req] = satisfiers

        return results

これらを参考にごにょごにょしてrdepなるコマンドを実装。

YUMBaseCli.__ini__ registerするコードを追加。
