======================
Test Message Catalog
======================
The test message catalog "translates" test by simply outputing (in
unicode) the domain and message id in square-bracket markers:
>>> import zope.i18n.testmessagecatalog
>>> cat = zope.i18n.testmessagecatalog.TestMessageCatalog('foo.bar')
>>> cat.language, cat.domain
('test', 'foo.bar')
>>> print(cat.queryMessage('eek'))
[[foo.bar][eek]]
>>> print(cat.getMessage('eek'))
[[foo.bar][eek]]
>>> isinstance(cat.getMessage('eek'), str if bytes is not str else unicode)
True
>>> cat.getIdentifier()
'test'
>>> cat.reload()
If a message id has a default, it will be included in the output:
>>> id = zope.i18nmessageid.MessageFactory('foo.bar')('eek', default='Eek')
>>> print(cat.queryMessage(id))
[[foo.bar][eek (Eek)]]
>>> print(cat.getMessage(id))
[[foo.bar][eek (Eek)]]
If a message doesn't have a default, but a default is passed in to
queryMessage, the default will be used used:
>>> print(cat.queryMessage('eek', default='Eek'))
[[foo.bar][eek (Eek)]]
>>> print(cat.getMessage(id, default='Waaa'))
[[foo.bar][eek (Eek)]]
Fallback domains
================
The testmessagecatalog module also provide a fallback domain factory
that has the test catalog as it's only catalog:
>>> factory = zope.i18n.testmessagecatalog.TestMessageFallbackDomain
>>> import zope.i18n.interfaces
>>> zope.i18n.interfaces.IFallbackTranslationDomainFactory.providedBy(
... factory)
True
>>> domain = factory('foo.bar')
>>> print(domain.translate('eek'))
eek
>>> print(domain.translate('eek', target_language='test'))
[[foo.bar][eek]]
Note that if a default is padded in, it will be included in test
output:
>>> print(domain.translate('eek', target_language='test', default='Eek'))
[[foo.bar][eek (Eek)]]
