NAME

     I18N::LangTags::Detect - detect the user's language prefer-
     ences

SYNOPSIS

       use I18N::LangTags::Detect;
       my @user_wants = I18N::LangTags::Detect::detect();

DESCRIPTION

     It is a common problem to want to detect what language(s)
     the user would prefer output in.

FUNCTIONS

     This module defines one public function,
     "I18N::LangTags::Detect::detect()".  This function is not
     exported (nor is even exportable), and it takes no parame-
     ters.

     In scalar context, the function returns the most preferred
     language tag (or undef if no preference was seen).

     In list context (which is usually what you want), the func-
     tion returns a (possibly empty) list of language tags
     representing (best first) what languages the user apparently
     would accept output in.  You will probably want to pass the
     output of this through
     "I18N::LangTags::implicate_supers_tightly(...)" or
     "I18N::LangTags::implicate_supers(...)", like so:

       my @languages =
         I18N::LangTags::implicate_supers_tightly(
           I18N::LangTags::Detect::detect()
         );

ENVIRONMENT

     This module looks for several environment variables, includ-
     ing REQUEST_METHOD, HTTP_ACCEPT_LANGUAGE, LANGUAGE, LC_ALL,
     LC_MESSAGES, and LANG.

     It will also use the Win32::Locale module, if it's
     installed.

SEE ALSO

     I18N::LangTags, Win32::Locale, Locale::Maketext.

     (This module's core code started out as a routine in
     Locale::Maketext; but I moved it here once I realized it was
     more generally useful.)
