84 I18N::Langinfo - query locale information
92 The langinfo() function queries various locale information that can be
93 used to localize output and user interfaces. The langinfo() requires
94 one numeric argument that identifies the locale constant to query:
95 if no argument is supplied, C<$_> is used. The numeric constants
96 appropriate to be used as arguments are exportable from I18N::Langinfo.
98 The following example will import the langinfo() function itself and
99 three constants to be used as arguments to langinfo(): a constant for
100 the abbreviated first day of the week (the numbering starts from
101 Sunday = 1) and two more constants for the affirmative and negative
102 answers for a yes/no question in the current locale.
104 use I18N::Langinfo qw(langinfo ABDAY_1 YESSTR NOSTR);
106 my ($abday_1, $yesstr, $nostr) = map { langinfo } qw(ABDAY_1 YESSTR NOSTR);
108 print "$abday_1? [$yesstr/$nostr] ";
110 In other words, in the "C" (or English) locale the above will probably
111 print something like:
115 but under a French locale
119 The usually available constants are
121 ABDAY_1 ABDAY_2 ABDAY_3 ABDAY_4 ABDAY_5 ABDAY_6 ABDAY_7
122 ABMON_1 ABMON_2 ABMON_3 ABMON_4 ABMON_5 ABMON_6
123 ABMON_7 ABMON_8 ABMON_9 ABMON_10 ABMON_11 ABMON_12
124 DAY_1 DAY_2 DAY_3 DAY_4 DAY_5 DAY_6 DAY_7
125 MON_1 MON_2 MON_3 MON_4 MON_5 MON_6
126 MON_7 MON_8 MON_9 MON_10 MON_11 MON_12
128 for abbreviated and full length days of the week and months of the year,
132 for the date-time, date, and time formats used by the strftime() function
135 AM_STR PM_STR T_FMT_AMPM
137 for the locales for which it makes sense to have ante meridiem and post
138 meridiem time formats,
140 CODESET CRNCYSTR RADIXCHAR
142 for the character code set being used (such as "ISO8859-1", "cp850",
143 "koi8-r", "sjis", "utf8", etc.), for the currency string, for the
144 radix character used between the integer and the fractional part
145 of decimal numbers (yes, this is redundant with POSIX::localeconv())
147 YESSTR YESEXPR NOSTR NOEXPR
149 for the affirmative and negative responses and expressions, and
151 ERA ERA_D_FMT ERA_D_T_FMT ERA_T_FMT
153 for the Japanese Emperor eras (naturally only defined under Japanese locales).
155 See your L<langinfo(3)> for more information about the available
156 constants. (Often this means having to look directly at the
157 F<langinfo.h> C header file.)
159 Note that unfortunately none of the above constants are guaranteed
160 to be available on a particular platform. To be on the safe side
161 you can wrap the import in an eval like this:
164 require I18N::Langinfo;
165 I18N::Langinfo->import(qw(langinfo CODESET));
166 $codeset = langinfo(CODESET()); # note the ()
168 if (!$@) { ... failed ... }
172 By default only the C<langinfo()> function is exported.
176 L<perllocale>, L<POSIX/localeconv>, L<POSIX/setlocale>, L<nl_langinfo(3)>.
178 The langinfo() is just a wrapper for the C nl_langinfo() interface.
