Hi folks,
I am trying to figure out why GNU gettext's behavior is not like strftime
or printf when it comes to localization. I read the entire manual from
A to Z but the examples are rather simple.
The task is to switch the locale in the application by user input to receive
localized file output.
Boiled down to a simple function:
void localize(char *locale, struct tm *time) {
printf("==============================================================\n");
printf("Passed locale: %s\n", locale);
char *setlocale_out = setlocale(LC_ALL, locale);
printf("Set locale: %s\n", setlocale_out);
char buffer[80];
strftime(buffer, sizeof(buffer), "%c", time);
printf("Localized time: %s\n", buffer);
printf("Get rational, π: %f\n", PI);
printf(_("Hello World!\n"));
printf(_("Goodbye!\n"));
}
bindtextdomain() and text() are called before localize(char *, struct tm *).
The entire
function is called within loop with different locales. However, The strings do
not change,
though strtime/printf obey the locale, gettext() ignores the change.
I have to call:
setenv("LANG", locale, 1);
bindtextdomain("my-i18n", LOCALEDIR);
textdomain("my-i18n");
before using _().
While I understand that bindtextdomain() caches stuff in memory, why do I have
to call
setenv too?
I have raised this some time ago on Stackoverflow [1] but was no given a
qualified answer
but for legacy support reasons.
I am on FreeBSD 9.3-STABLE with gettext 0.19.8.1
