This causes _ to become a local that is left undefined on one
branch of the if. You need to ensure it's always defined. Here's
one way that should work:
gttran = _
def foobar(translate):
def _(txt):
if translate:
return gttran(txt)
else:
return txt
return _('Hello')

One thing to remember is that the _() function, which calls gettext doesn’t
need a literal string, so you can set a variable to ‘raw’ string, and then
translate it to another variable, so you can have both.

Is it an option for you to replace the `gettext` binding by `zope.i18nmessageid`? Its `Message` instances provide access to all interesting attributes (id, default, mapping, domain). Together with other packages (--> `zope.i18n` and `i18ndude`) it is compatible with `GNU gettext` translation catalogs. If this is not an option, use Python's inspection functionality to learn which attributes are made available by the binding's message class. -- https://mail.python.org/mailman/listinfo/python-list

UnboundLocalError: local variable '_' referenced before assignment
This is a common gotcha:
https://docs.python.org/3/faq/programming.html#why-am-i-getting-an-unboundlocalerror-when-the-variable-has-a-value
You could solve it by defining _() locally like so:
def foobar(translate):
_ = gettext.gettext
if not translate:
# I try to mask the global _() builtins-function
def _(txt):
return txt
return _('minutes')
The question is if this can be solved somehow or if there is an alternative
approach.
However, you might not need this, because the following seems to
work for me:
def orig_and_trans(msg):
return (_(msg), msg)
print('The translated string "{}" is originally
"{}".'.format(*orig_and_trans("hello")))

GNU gettext: Print string translated and untranslated at the same time
X-Post: https://stackoverflow.com/q/76913082/4865723
I want to display one string in its original source (untranslated)
version and in its translated version site by site without duplicating
the string in the python source code?
It wouldn't be a big deal if it is only one word.
print('The translated string "{}" is originally
"{}".'.format(_('Hello'), 'Hello'))
But in my situation it is a multi line string containing multiple
paragraphs. It is a full text. I don't want to duplicate that string.
# Imagine 'Hello' as a 50x70 characters multi line string.
original = 'Hello'
translated = _('Hello')
print('The translated string "{}" is originally
"{}".'.format(translated, original))
I do use the "class based API" of GNU gettext. My current approach,
which is not working, is to somehow (how!?) disable (or mask) the
translation function "_()" temporarily.
But as described in the stackoverflow question (see first line of this
mail) this do not work.
def foobar(translate):
if not translate:
# I try to mask the global _() builtins-function
def _(txt):
return txt
return _('Hello')
if __name__ == '__main__':
# To ilustrate that _() is part of "builtins" namespace
print(_('No problem.'))
print('The translated string "{}" is originally "{}".'
.format(foobar(True), foobar(False)))
This is the output:
Traceback (most recent call last):
File "/home/user/ownCloud/_transfer/./z.py", line 27, in
.format(foobar(True), foobar(False)))
File "/home/user/ownCloud/_transfer/./z.py", line 19, in foobar
return _('Hello')
UnboundLocalError: local variable '_' referenced before assignment
The full MWE can be found at stackoverflow
(https://stackoverflow.com/q/76913082/4865723).
The question is if this can be solved somehow or if there is an
alternative approach.
The "_()" function is installed in the builtins namespace because of
gettext class based API. This is nice.
Maybe I can somehow manipulate that builtins namespace? I tried to
import builtins and played around with it but couldn't find a way to do
it.
