I checked the TG source and did not find a standard way, except that it
is possible to give the domain (and with it the filename
) to the gettext function.
Therefore it is possible to create a message.mo file for the costum
messages of a specific TG Project (no change in this process), and in
the same directory (locales) a FormEncode.mo which includes the
translations of the standard FormEncode messages and a TG.mo for TG's
standard validator messages.
TG should install FormEncode.mo and TG.mo automatically with tg-admin
quickstart.
To enable this there must be a way of telling FormEncode to call TG's
gettext function with the argument domain=FormEncode (so the
FormEncode.mo file is used for translation instead of the standard
messages.mo)
I therefore propose a new class attribute: formencode.Validator.gettextargs
For standalone FormEncode this attribute is {}. (Because standard
gettext function does not allow additional parameters)
<formencode.api.py>
class Validator(declarative.Declarative):
[....]
gettextargs = {}
[...]
def message(self, msgName, state, **kw):
#determine translation function
try:
trans = state._
except AttributeError:
try:
import __builtin__
trans = __builtin__._
except AttributeError:
trans = _stdtrans
try:
return trans(self._messages[msgName], **self.gettextargs) % kw
except KeyError, e:
raise KeyError(
"Key not found (%s) for %r=%r %% %r (from: %s)"
% (e, msgName, self._messages.get(msgName), kw,
', '.join(self._messages.keys())))
</formencode.api.py>
TG has to setup this argument in turbogears.validators.py:
<turbogears.validators.py>
....
from formencode.validators import *
....
Validator.gettextargs = {'domain':'FormEncode'}
</turbogears.validators.py>
Is this concept OK?
The protoype works.
If it's OK I am going to make a patch to TG's trunk and apply the
changes to http://svn.colorstudy.com/FormEncode/branches/gettext-enabled/
