PROLOG
This manual page is part of the POSIX Programmer's Manual. The Linux
implementation of this interface may differ (consult the corresponding
Linux manual page for details of Linux behavior), or the interface may
not be implemented on Linux.
NAME
localedef - define locale environment
SYNOPSIS
localedef [-c][-f charmap][-i sourcefile][-u code_set_name] name
DESCRIPTION
The localedef utility shall convert source definitions for locale cate-
gories into a format usable by the functions and utilities whose opera-
tional behavior is determined by the setting of the locale environment
variables defined in the Base Definitions volume of
IEEE Std 1003.1-2001, Chapter 7, Locale. It is implementation-defined
whether users have the capability to create new locales, in addition to
those supplied by the implementation. If the symbolic constant
POSIX2_LOCALEDEF is defined, the system supports the creation of new
locales. On XSI-conformant systems, the symbolic constant
POSIX2_LOCALEDEF shall be defined.
The utility shall read source definitions for one or more locale cate-
gories belonging to the same locale from the file named in the -i
option (if specified) or from standard input.
The name operand identifies the target locale. The utility shall sup-
port the creation of public, or generally accessible locales, as well
as private, or restricted-access locales. Implementations may restrict
the capability to create or modify public locales to users with the
appropriate privileges.
Each category source definition shall be identified by the correspond-
ing environment variable name and terminated by an END category-name
statement. The following categories shall be supported. In addition,
the input may contain source for implementation-defined categories.
LC_CTYPE
Defines character classification and case conversion.
LC_COLLATE
Defines collation rules.
LC_MONETARY
Defines the format and symbols used in formatting of monetary
information.
LC_NUMERIC
Defines the decimal delimiter, grouping, and grouping symbol for
non-monetary numeric editing.
LC_TIME
Defines the format and content of date and time information.
LC_MESSAGES
Defines the format and values of affirmative and negative
responses.
OPTIONS
The localedef utility shall conform to the Base Definitions volume of
IEEE Std 1003.1-2001, Section 12.2, Utility Syntax Guidelines.
The following options shall be supported:
-c Create permanent output even if warning messages have been
issued.
-f charmap
Specify the pathname of a file containing a mapping of character
symbols and collating element symbols to actual character encod-
ings. The format of the charmap is described in the Base Defini-
tions volume of IEEE Std 1003.1-2001, Section 6.4, Character Set
Description File. The application shall ensure that this option
is specified if symbolic names (other than collating symbols
defined in a collating-symbol keyword) are used. If the -f
option is not present, an implementation-defined character map-
ping shall be used.
-i inputfile
The pathname of a file containing the source definitions. If
this option is not present, source definitions shall be read
from standard input. The format of the inputfile is described in
the Base Definitions volume of IEEE Std 1003.1-2001, Section
7.3, Locale Definition.
-u code_set_name
Specify the name of a codeset used as the target mapping of
character symbols and collating element symbols whose encoding
values are defined in terms of the ISO/IEC 10646-1:2000 standard
position constant values.
OPERANDS
The following operand shall be supported:
name Identifies the locale; see the Base Definitions volume of
IEEE Std 1003.1-2001, Chapter 7, Locale for a description of the
use of this name. If the name contains one or more slash charac-
ters, name shall be interpreted as a pathname where the created
locale definitions shall be stored. If name does not contain any
slash characters, the interpretation of the name is implementa-
tion-defined and the locale shall be public. This capability may
be restricted to users with appropriate privileges. (As a conse-
quence of specifying one name, although several categories can
be processed in one execution, only categories belonging to the
same locale can be processed.)
STDIN
Unless the -i option is specified, the standard input shall be a text
file containing one or more locale category source definitions, as
described in the Base Definitions volume of IEEE Std 1003.1-2001, Sec-
tion 7.3, Locale Definition. When lines are continued using the escape
character mechanism, there is no limit to the length of the accumulated
continued line.
INPUT FILES
The character set mapping file specified as the charmap option-argument
is described in the Base Definitions volume of IEEE Std 1003.1-2001,
Section 6.4, Character Set Description File. If a locale category
source definition contains a copy statement, as defined in the Base
Definitions volume of IEEE Std 1003.1-2001, Chapter 7, Locale, and the
copy statement names a valid, existing locale, then localedef shall
behave as if the source definition had contained a valid category
source definition for the named locale.
ENVIRONMENT VARIABLES
The following environment variables shall affect the execution of
localedef:
LANG Provide a default value for the internationalization variables
that are unset or null. (See the Base Definitions volume of
IEEE Std 1003.1-2001, Section 8.2, Internationalization Vari-
ables for the precedence of internationalization variables used
to determine the values of locale categories.)
LC_ALL If set to a non-empty string value, override the values of all
the other internationalization variables.
LC_COLLATE
(This variable has no affect on localedef; the POSIX locale is
used for this category.)
LC_CTYPE
Determine the locale for the interpretation of sequences of
bytes of text data as characters (for example, single-byte as
opposed to multi-byte characters in arguments and input files).
This variable has no affect on the processing of localedef input
data; the POSIX locale is used for this purpose, regardless of
the value of this variable.
LC_MESSAGES
Determine the locale that should be used to affect the format
and contents of diagnostic messages written to standard error.
NLSPATH
Determine the location of message catalogs for the processing of
LC_MESSAGES .
ASYNCHRONOUS EVENTS
Default.
STDOUT
The utility shall report all categories successfully processed, in an
unspecified format.
STDERR
The standard error shall be used only for diagnostic messages.
OUTPUT FILES
The format of the created output is unspecified. If the name operand
does not contain a slash, the existence of an output file for the
locale is unspecified.
EXTENDED DESCRIPTION
When the -u option is used, the code_set_name option-argument shall be
interpreted as an implementation-defined name of a codeset to which the
ISO/IEC 10646-1:2000 standard position constant values shall be con-
verted via an implementation-defined method. Both the
ISO/IEC 10646-1:2000 standard position constant values and other for-
mats (decimal, hexadecimal, or octal) shall be valid as encoding values
within the charmap file. The codeset represented by the implementation-
defined name can be any codeset that is supported by the implementa-
tion.
When conflicts occur between the charmap specification of
<code_set_name>, <mb_cur_max>, or <mb_cur_min> and the implementation-
defined interpretation of these respective items for the codeset repre-
sented by the -u option-argument code_set_name, the result is unspeci-
fied.
When conflicts occur between the charmap encoding values specified for
symbolic names of characters of the portable character set and the
implementation-defined assignment of character encoding values, the
result is unspecified.
If a non-printable character in the charmap has a width specified that
is not -1, localedef shall generate a warning.
EXIT STATUS
The following exit values shall be returned:
0 No errors occurred and the locales were successfully created.
1 Warnings occurred and the locales were successfully created.
2 The locale specification exceeded implementation limits or the
coded character set or sets used were not supported by the
implementation, and no locale was created.
3 The capability to create new locales is not supported by the
implementation.
>3 Warnings or errors occurred and no output was created.
CONSEQUENCES OF ERRORS
If an error is detected, no permanent output shall be created.
If warnings occur, permanent output shall be created if the -c option
was specified. The following conditions shall cause warning messages to
be issued:
* If a symbolic name not found in the charmap file is used for the
descriptions of the LC_CTYPE or LC_COLLATE categories (for other
categories, this shall be an error condition).
* If the number of operands to the order keyword exceeds the
{COLL_WEIGHTS_MAX} limit.
* If optional keywords not supported by the implementation are present
in the source.
* If a non-printable character has a width specified other than -1.
Other implementation-defined conditions may also cause warnings.
The following sections are informative.
APPLICATION USAGE
The charmap definition is optional, and is contained outside the locale
definition. This allows both completely self-defined source files, and
generic sources (applicable to more than one codeset). To aid portabil-
ity, all charmap definitions must use the same symbolic names for the
portable character set. As explained in the Base Definitions volume of
IEEE Std 1003.1-2001, Section 6.4, Character Set Description File, it
is implementation-defined whether or not users or applications can pro-
vide additional character set description files. Therefore, the -f
option might be operable only when an implementation-defined charmap is
named.
EXAMPLES
None.
RATIONALE
The output produced by the localedef utility is implementation-defined.
The name operand is used to identify the specific locale. (As a conse-
quence, although several categories can be processed in one execution,
only categories belonging to the same locale can be processed.)
FUTURE DIRECTIONS
None.
