from zope import schema
from zope.schema.vocabulary import SimpleVocabulary

VARIETALS = """Cabernet Franc
Cabernet Sauvignon
Chardonnay
Chenin Blanc
Claret
Gewurztraminer
Grenache
Malbec
Marsanne
Merlot
Petit Syrah
Petit Verdot"""

class VarietalsSource(object):
    def __call__(self, context):
        values = VARIETALS.splitlines()
        return  SimpleVocabulary.fromValues(values)
       
grok.global_utility(VarietalsSource,
                    provides=schema.interfaces.IVocabularyFactory,
                    name=u'VarietalsSource')
