108 I18N::Langinfo - query locale information
116 The langinfo() function queries various locale information that can be
117 used to localize output and user interfaces. The langinfo() requires
118 one numeric argument that identifies the locale constant to query:
119 if no argument is supplied, C<$_> is used. The numeric constants
120 appropriate to be used as arguments are exportable from I18N::Langinfo.
122 The following example will import the langinfo() function itself and
123 three constants to be used as arguments to langinfo(): a constant for
124 the abbreviated first day of the week (the numbering starts from
125 Sunday = 1) and two more constants for the affirmative and negative
126 answers for a yes/no question in the current locale.
128 use I18N::Langinfo qw(langinfo ABDAY_1 YESSTR NOSTR);
130 my ($abday_1, $yesstr, $nostr) = map { langinfo } qw(ABDAY_1 YESSTR NOSTR);
132 print "$abday_1? [$yesstr/$nostr] ";
134 In other words, in the "C" (or English) locale the above will probably
135 print something like:
139 The usually available constants are
141 ABDAY_1 ABDAY_2 ABDAY_3 ABDAY_4 ABDAY_5 ABDAY_6 ABDAY_7
142 ABMON_1 ABMON_2 ABMON_3 ABMON_4 ABMON_5 ABMON_6
143 ABMON_7 ABMON_8 ABMON_9 ABMON_10 ABMON_11 ABMON_12
144 DAY_1 DAY_2 DAY_3 DAY_4 DAY_5 DAY_6 DAY_7
145 MON_1 MON_2 MON_3 MON_4 MON_5 MON_6
146 MON_7 MON_8 MON_9 MON_10 MON_11 MON_12
148 for abbreviated and full length days of the week and months of the year,
152 for the date-time, date, and time formats used by the strftime() function
153 (see L<POSIX>, and also L<Time::Piece>),
155 AM_STR PM_STR T_FMT_AMPM
157 for the locales for which it makes sense to have ante meridiem and post
158 meridiem time formats,
160 CODESET CRNCYSTR RADIXCHAR
162 for the character code set being used (such as "ISO8859-1", "cp850",
163 "koi8-r", "sjis", "utf8", etc.), for the currency string, for the
164 radix character (yes, this is redundant with POSIX::localeconv())
166 YESSTR YESEXPR NOSTR NOEXPR
168 for the affirmative and negative responses and expressions, and
170 ERA ERA_D_FMT ERA_D_T_FMT ERA_T_FMT
172 for the Japanese Emperor eras (naturally only defined under Japanese locales).
174 See your L<langinfo(3)> for more information about the available
175 constants. (Often this means having to look directly at the
176 F<langinfo.h> C header file.)
180 Nothing is exported by default.
184 L<perllocale>, L<POSIX/localeconv>, L<POSIX/setlocale>, L<nl_langinfo(3)>.
186 The langinfo() is just a wrapper for the C nl_langinfo() interface.
