I came up with something like
the attached group, but it fails with
error: /home/mark/conary/src/fedora-20/group-fedora/group-fedora.recipe:26:
AttributeError: 'list' object has no attribute '_createGroup'
Any hints?
the comps-f20.xml file I got from
http://dl.fedoraproject.org/pub/fedora/linux/releases/20/Everything/x86_64/os/repodata/
recipe looks like that:
import xml.etree.ElementTree as ET
class GroupFedora(GroupSetRecipe):
name = 'group-fedora'
version = '20'
def setup(r):
r.dumpAll()
repo = r.Repository('f20s1.flnx.org@f:20sbeta', r.flavor)
latest = repo.latestPackages()
# xml magic here
comps = ET.parse('comps-f20.xml')
root = comps.getroot()
groups = []
for g in root.findall('group'):
pkglist = set()
for pkg in g.find ('packagelist'):
pkglist.add(pkg.text)
group = latest.findByName('(' + '|'.join(pkglist) + ')')
group += group.depsNeeded(latest)
groups.append(group.createGroup('group-' +
g.find('id').text))
r.Group(groups)
