I18N::LangTags::Detect(3pm)                     Perl Programmers Reference Guide                     I18N::LangTags::Detect(3pm)



NAME
       I18N::LangTags::Detect - detect the user's language preferences

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 parameters.

       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 function 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, including 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.)
