- \page faq Frequently Asked Questions
- - \anchor faq_bad_cast <b>I try to use some Boost.Locale functions and I get an \c std::bad_cast exception thrown?</b>
- \n

- \b Answer: You probably try to use incorrect \c std::locale object. All Boost.Locale tools relay on \c std::locale object's facets.
- The locale object should be generated with \ref boost::locale::generator "generator" class and then passed to
- the function or alternatively global locale should be set using \c std::locale::global() function such that
- global locale (and default created one) would have required facets to use.
- - \anchor faq_number <b>I had installed global locale and try to write something to stream but still get wrong output?</b>
- For example:
- \code
- #include <boost/locale.hpp>
- #include <iostream>
- int main()
- {
- boost::locale::generator gen;
- std::locale::global(gen(""));
- std::cout << boost::locale::as::date << std::time(0) << std::endl;
- }
- \endcode
- Prints a number instead of a date.
- \n
- \b Answer: You forget to imbue the locale to the stream. Changing the global locale does not affect the
- locale in existing \c iostream objects. Thus because \c std::out and other global streams were created
- before changing the global locale Boost.Locale manipulators have no effect. You need to write:
- \code
- #include <boost/locale.hpp>
- #include <iostream>
- int main()
- {
- boost::locale::generator gen;
- std::locale l = gen("");
- std::locale::global(l);
- std::cout.imbue(l);
- std::cout << boost::locale::as::date << std::time(0) << std::endl;
- }
- \endcode
