NAME

SDL2::locale - SDL Locale Services

SYNOPSIS

use SDL2 qw[:locale];
my $locale = SDL_GetPreferredLocales( )->[0];

DESCRIPTION

SDL2::locale represents the user's preferred locale.

Functions

These may be imported by name or with the :locale tag.

SDL_GetPreferredLocales( )

Report the user's preferred locale.

my $locale = SDL_GetPreferredLocales( )->[0];
warn $locale->language;
warn $locale->country;

This returns an array of SDL2::Locale structs, the final item zeroed out.

Returned language strings are in the format xx, where 'xx' is an ISO-639 language specifier (such as "en" for English, "de" for German, etc). Country strings are in the format YY, where "YY" is an ISO-3166 country code (such as "US" for the United States, "CA" for Canada, etc). Country might be NULL if there's no specific guidance on them (so you might get { "en", "US" } for American English, but { "en", undef } means "English language, generically"). Language strings are never undef, except to terminate the array.

Please note that not all of these strings are 2 characters; some are three or more.

The returned list of locales are in the order of the user's preference. For example, a German citizen that is fluent in US English and knows enough Japanese to navigate around Tokyo might have a list like: [ "de", "en_US", "jp", undef ]. Someone from England might prefer British English (where "color" is spelled "colour", etc), but will settle for anything like it: [ "en_GB", "en", undef ].

This function returns undef on error, including when the platform does not supply this information at all.

This might be a "slow" call that has to query the operating system. It's best to ask for this once and save the results. However, this list can change, usually because the user has changed a system preference outside of your program; SDL will send an SDL_LOCALECHANGED event in this case, if possible, and you can call this function again to get an updated copy of preferred locales.

Returns an array of locales, terminated with a locale with an undef language field. Will return undef on error.
