I have recently updated my code to use the more pythonic f-string
instead of '{}'.format()
Now, I want to start on the road to multilingual internationalization,
and I run into two problems. The first problem is that f-strings do not
combine with i18n. I have to revert to the '{}'.format() style.
The second problem is that I need to translate strings on the fly. I
propose to add a f''.language() method to the f-string format.
Example:
user = 'Pedro'
f'Hi {user}' would be translated to 'Hola Pedro' if the locale were set
to Spanish.
f'Hi {user}'.language('es_ES') would be translated in the same way.
To extract translatable strings from the source code, the source code
could contain a 'HAS_LOCALES' flag (or something similar) at the top of
the code. This way, the pygettext.py program would know that
translatable f-strings are within the code.
Rationale:
More pythonic. At this moment, _('').format() is the way to go, so I
would need to wrap another call around that: T(_(''), args, 'es_ES')
<===This is an ugly hack.
# Set the _() function to return the same string
_ = lambda s: s
es = gettext.translation('myapplication', languages=['es_ES'])
def T(translatable_string, args_dictionary = None, language = None)
if 'es_ES' == language:
# Return translated, formatted string
return es.gettext(translatable_string).format(args)
# Default, return formatted string
return translatable_string.format(args)
