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) 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 By default only the "langinfo()" function is exported.

langinfo.h(3HEAD) Headers langinfo.h(3HEAD) NAME
langinfo.h, langinfo - language information constants SYNOPSIS
#include <langinfo.h> DESCRIPTION
The <langinfo.h> header contains the constants used to identify items of langinfo data (see nl_langinfo(3C)). The type of the constant, nl_item, is defined as described in <nl_types.h>. The following constants are defined. The entries under Category indicate in which setlocale(3C) category each item is defined. Constant Category Meaning CODESET LC_CTYPE codeset name D_T_FMT LC_TIME string for formatting date and time D_FMT LC_TIME date format string T_FMT LC_TIME time format string T_FMT_AMPM LC_TIME a.m. or p.m. time format string AM_STR LC_TIME ante-meridiem affix PM_STR LC_TIME post-meridiem affix DAY_1 LC_TIME name of the first day of the week (for example, Sunday) DAY_2 LC_TIME name of the second day of the week (for example, Monday) DAY_3 LC_TIME name of the third day of the week (for example, Tuesday) DAY_4 LC_TIME name of the fourth day of the week (for example, Wednesday) DAY_5 LC_TIME name of the fifth day of the week (for example, Thursday) DAY_6 LC_TIME name of the sixth day of the week (for example, Friday) DAY_7 LC_TIME name of the seventh day of the week (for example, Saturday) ABDAY_1 LC_TIME abbreviated name of the first day of the week ABDAY_2 LC_TIME abbreviated name of the second day of the week ABDAY_3 LC_TIME abbreviated name of the third day of the week ABDAY_4 LC_TIME abbreviated name of the fourth day of the week ABDAY_5 LC_TIME abbreviated name of the fifth day of the week ABDAY_6 LC_TIME abbreviated name of the seventh day of the week ABDAY_7 LC_TIME abbreviated name of the seventh day of the week MON_1 LC_TIME name of the first month of the year MON_2 LC_TIME name of the second month MON_3 LC_TIME name of the third month MON_4 LC_TIME name of the fourth month MON_5 LC_TIME name of the fifth month MON_6 LC_TIME name of the sixth month MON_7 LC_TIME name of the seventh month MON_8 LC_TIME name of the eighth month MON_9 LC_TIME name of the ninth month MON_10 LC_TIME name of the tenth month MON_11 LC_TIME name of the eleventh month MON_12 LC_TIME name of the twelfth month ABMON_1 LC_TIME abbreviated name of the first month ABMON_2 LC_TIME abbreviated name of the second month ABMON_3 LC_TIME abbreviated name of the third month ABMON_4 LC_TIME abbreviated name of the fourth month ABMON_5 LC_TIME abbreviated name of the fifth month ABMON_6 LC_TIME abbreviated name of the sixth month ABMON_7 LC_TIME abbreviated name of the seventh month ABMON_8 LC_TIME abbreviated name of the eighth month ABMON_9 LC_TIME abbreviated name of the ninth month ABMON_10 LC_TIME abbreviated name of the tenth month ABMON_11 LC_TIME abbreviated name of the eleventh month ABMON_12 LC_TIME abbreviated name of the twelfth month ERA LC_TIME era description segments ERA_D_FMT LC_TIME era date format string ERA_D_T_FMT LC_TIME era date and time format string ERA_T_FMT LC_TIME era time format string ALT_DIGITS LC_TIME alternative symbols for digits RADIXCHAR LC_NUMERIC radix character THOUSEP LC_NUMERIC separator for thousands YESEXPR LC_MESSAGES affirmative response expression NOEXPR LC_MESSAGES negative response expression YESSTR LC_MESSAGES affirmative response for yes/no queries NOSTR LC_MESSAGES negative response ro yes/no queries CRNCYSTR LC_MONETARY local currency symbol, preceded by '-' if the symbol sould appear before the value, '+' if the symbol should appear after the value, or '.' if the symbol should replace the radix character If the locale's values for p_cs_precedes and n_cs_precedes do not match, the value of nl_langinfo(CRNCYSTR) is unspecified. The <langinfo.h> header declares the following as a function: char *nl_langinfo(nl_item); Inclusion of <langinfo.h> header may also make visible all symbols from <nl_types.h>. USAGE
Wherever possible, users are advised to use functions compatible with those in the ISO C standard to access items of langinfo data. In par- ticular, the strftime(3C) function should be used to access date and time information defined in category LC_TIME. The localeconv(3C) func- tion should be used to access information corresponding to RADIXCHAR, THOUSEP, and CRNCYSTR. ATTRIBUTES
