LOCALEDEF(P) LOCALEDEF(P)
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 categories into a
format usable by the functions and utilities whose operational behavior is deter-
mined by the setting of the locale environment variables defined in the Base Defi-
nitions 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 sys-
tems, the symbolic constant POSIX2_LOCALEDEF shall be defined.
The utility shall read source definitions for one or more locale categories belong-
ing 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 support the cre-
ation 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 corresponding environ-
ment variable name and terminated by an END category-name statement. The following
categories shall be supported. In addition, the input may contain source for imple-
mentation-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-mone-
tary 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 encodings. The format of the
charmap is described in the Base Definitions 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 sym-
bols defined in a collating-symbol keyword) are used. If the -f option is
not present, an implementation-defined character mapping 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 for-
mat 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 sym-
bols 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 characters, 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 implementation-defined and the locale shall be public. This
capability may be restricted to users with appropriate privileges. (As a
consequence of specifying one name, although several categories can be pro-
cessed 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 contain-
ing one or more locale category source definitions, as described in the Base Defi-
nitions volume of IEEE Std 1003.1-2001, Section 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 Variables for the precedence of interna-
tionalization 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 char-
acters in arguments and input files). This variable has no affect on the
processing of localedef input data; the POSIX locale is used for this pur-
pose, 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 con-
tain 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 converted via an implementation-defined
method. Both the ISO/IEC 10646-1:2000 standard position constant values and other
formats (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 implementation.
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 represented by the -u option-argument
code_set_name, the result is unspecified.
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 charac-
ter 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 speci-
fied. 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 (appli-
cable to more than one codeset). To aid portability, 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 provide 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 consequence, although sev-
eral categories can be processed in one execution, only categories belonging to the
same locale can be processed.)
FUTURE DIRECTIONS
None.
