NAME
locale - describes a locale definition file
DESCRIPTION
The locale definition file contains all the information that the localedef(1) command
needs to convert it into the binary locale database.
The definition files consist of sections which each describe a locale category in detail.
See locale(7) for additional details for these categories.
Syntax
The locale definition file starts with a header that may consist of the following
keywords:
escape_char
is followed by a character that should be used as the escape-character for the rest
of the file to mark characters that should be interpreted in a special way. It
defaults to the backslash (\).
comment_char
is followed by a character that will be used as the comment-character for the rest
of the file. It defaults to the number sign (#).
The locale definition has one part for each locale category. Each part can be copied from
another existing locale or can be defined from scratch. If the category should be copied,
the only valid keyword in the definition is copy followed by the name of the locale in
double quotes which should be copied. The exceptions for this rule are LC_COLLATE and
LC_CTYPE where a copy statement can be followed by locale-specific rules and selected
overrides.
When defining a locale or a category from scratch, an existing system- provided locale
definition file should be used as a reference to follow common glibc conventions.
Locale category sections
The following category sections are defined by POSIX:
* LC_CTYPE
* LC_COLLATE
* LC_MESSAGES
* LC_MONETARY
* LC_NUMERIC
* LC_TIME
In addition, since version 2.2, the GNU C library supports the following nonstandard
categories:
* LC_ADDRESS
* LC_IDENTIFICATION
* LC_MEASUREMENT
* LC_NAME
* LC_PAPER
* LC_TELEPHONE
See locale(7) for a more detailed description of each category.
LC_ADDRESS
The definition starts with the string LC_ADDRESS in the first column.
The following keywords are allowed:
postal_fmt
followed by a string containing field descriptors that define the format used for
postal addresses in the locale. The following field descriptors are recognized:
%n Person's name, possibly constructed with the LC_NAME name_fmt keyword (since
glibc 2.24).
%a Care of person, or organization.
%f Firm name.
%d Department name.
%b Building name.
%s Street or block (e.g., Japanese) name.
%h House number or designation.
%N Insert an end-of-line if the previous descriptor's value was not an empty
string; otherwise ignore.
%t Insert a space if the previous descriptor's value was not an empty string;
otherwise ignore.
%r Room number, door designation.
%e Floor number.
%C Country designation, from the country_post keyword.
%l Local township within town or city (since glibc 2.24).
%z Zip number, postal code.
%T Town, city.
%S State, province, or prefecture.
%c Country, as taken from data record.
Each field descriptor may have an 'R' after the '%' to specify that the information
is taken from a Romanized version string of the entity.

FILES
/usr/lib/locale/locale-archive

CONFORMING TO
POSIX.2.
NOTES
The collective GNU C library community wisdom regarding abday, day, week, first_weekday,
and first_workday states at https://sourceware.org/glibc/wiki/Locales the following:
* The value of the second week list item specifies the base of the abday and day lists.
* first_weekday specifies the offset of the first day-of-week in the abday and day lists.
* For compatibility reasons, all glibc locales should set the value of the second week
list item to 19971130 (Sunday) and base the abday and day lists appropriately, and set
first_weekday and first_workday to 1 or 2, depending on whether the week and work week
actually starts on Sunday or Monday for the locale.
