I18N::LangTags::Detect - phpMan

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 at several environment variables: REQUEST_METHOD,
    HTTP_ACCEPT_LANGUAGE, LANGUAGE, LC_ALL, LC_MESSAGES, and LANG.

    It will also use the Win32::Locale module, if it's installed and
    IGNORE_WIN32_LOCALE is not set to a true value in the environment.

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.)
