NAME
       I18N::Langinfo - query locale information

SYNOPSIS
         use I18N::Langinfo;

DESCRIPTION
       The langinfo() function queries various locale information
       that can be used to localize output and user interfaces.
       The langinfo() requires one numeric argument that
       identifies the locale constant to query: if no argument is
       supplied, $_ is used.  The numeric constants appropriate
       to be used as arguments are exportable from
       I18N::Langinfo.

       The following example will import the langinfo() function
       itself and three constants to be used as arguments to
       langinfo(): a constant for the abbreviated first day of
       the week (the numbering starts from Sunday = 1) and two
       more constants for the affirmative and negative answers
       for a yes/no question in the current locale.

           use I18N::Langinfo qw(langinfo ABDAY_1 YESSTR NOSTR);

           my ($abday_1, $yesstr, $nostr) = map { langinfo } qw(ABDAY_1 YESSTR NOSTR);

           print "$abday_1? [$yesstr/$nostr] ";

       In other words, in the "C" (or English) locale the above
       will probably print something like:

           Sun? [yes/no]

       but under a French locale

           dim? [oui/non]

       The usually available constants are

           ABDAY_1 ABDAY_2 ABDAY_3 ABDAY_4 ABDAY_5 ABDAY_6 ABDAY_7
           ABMON_1 ABMON_2 ABMON_3 ABMON_4 ABMON_5 ABMON_6
           ABMON_7 ABMON_8 ABMON_9 ABMON_10 ABMON_11 ABMON_12
           DAY_1 DAY_2 DAY_3 DAY_4 DAY_5 DAY_6 DAY_7
           MON_1 MON_2 MON_3 MON_4 MON_5 MON_6
           MON_7 MON_8 MON_9 MON_10 MON_11 MON_12

       for abbreviated and full length days of the week and
       months of the year,

           D_T_FMT D_FMT T_FMT

       for the date-time, date, and time formats used by the
       strftime() function (see POSIX)

ext::I18N-LanginfPerlaProgrammersext::I18N-Langinfo::Langinfo(3p)


           AM_STR PM_STR T_FMT_AMPM

       for the locales for which it makes sense to have ante
       meridiem and post meridiem time formats,

           CODESET CRNCYSTR RADIXCHAR

       for the character code set being used (such as
       "ISO8859-1", "cp850", "koi8-r", "sjis", "utf8", etc.), for
       the currency string, for the radix character used between
       the integer and the fractional part of decimal numbers
       (yes, this is redundant with POSIX::localeconv())

           YESSTR YESEXPR NOSTR NOEXPR

       for the affirmative and negative responses and
       expressions, and

           ERA ERA_D_FMT ERA_D_T_FMT ERA_T_FMT

       for the Japanese Emperor eras (naturally only defined
       under Japanese locales).

       See your langinfo(3) for more information about the
       available constants.  (Often this means having to look
       directly at the langinfo.h C header file.)

       Note that unfortunately none of the above constants are
       guaranteed to be available on a particular platform.  To
       be on the safe side you can wrap the import in an eval
       like this:

           eval {
               require I18N::Langinfo;
               I18N::Langinfo->import(qw(langinfo CODESET));
               $codeset = langinfo(CODESET()); # note the ()
           };
           if (!$@) { ... failed ... }

   EXPORT
       Nothing is exported by default.

SEE ALSO
       perllocale, "localeconv" in POSIX, "setlocale" in POSIX,
       nl_langinfo(3).

       The langinfo() is just a wrapper for the C nl_langinfo()
       interface.
