I looked at this briefly tonight. There appears to be no sexy way to
do this that I can think of. Mainly because Python doesn't like the
idea of vars() being monkeyed with. According to the documentation[1]
for vars():
vars([object])
Without arguments, return a dictionary corresponding to the
current local symbol table. With a module, class or class
instance object as argument (or anything else that has a
__dict__ attribute), returns a dictionary corresponding to the
object's symbol table. The returned dictionary should not be
modified: the effects on the corresponding symbol table are
undefined.
Thus, even something like the following at the end of Defaults.py
blows up with a RuntimeError:
for k,v in vars().iteritems():
if isinstance(v, str):
print '%s = %s' % (k,v)
You have to query vars().copy() instead before all is good.
However, I don't think we want to run os.path.expanduser() on _every_
string variable anyway, as there are many where this isn't
appropriate.
ACTION_EXPIRED_DATED = 'confirm'
DATED_TIMEOUT = '5d'
FULLNAME = 'Jason R. Mastaler'
etc..
So perhaps we have to just do the tilde expansion on a case by case
basis in Defaults.py? e.g,
if not vars().has_key('TEMPLATE_DIR'):
TEMPLATE_DIR = None
else:
TEMPLATE_DIR = os.path.expanduser(TEMPLATE_DIR)
