localedef(1)
NAME
localedef - Builds a locale from locale and character map source files
SYNOPSIS
localedef [-C compiler_options] [-c] [-f character_map] [-i sourcefile]
[-L linker_options] [-m methodfile] [-P tool_path] [-v] [-w] localename
STANDARDS
Interfaces documented on this reference page conform to industry standards
as follows:
localedef: XCU5.0
See standards(5) for more information about industry standards and
associated tags.
OPTIONS
-C compiler_options
[Tru64 UNIX] Passes the specified options to the compiler that builds
the locale. If you are specifying more than one option, enclose the
list in double quotes.
-c Forces the creation of locale tables. You must use this option if you
have received warning messages; otherwise, the locale tables will not
be created.
-f character_map
Specifies a file that maps character and collating symbols to actual
character encodings. Using the -f option allows one source definition
to be applicable to more than one codeset. If this option is not
specified, the Portable Character Set (PCS) is used. The -f option must
be used if symbolic names (other than collating symbols defined in a
collating-symbol keyword) are used. See charmap(4) for more information
about a character map file.
-i sourcefile
Specifies the pathname of a file containing the locale category source
definitions. If this option is not present, source definitions are
read from standard input. See locale(4) for more information about
sourcefile.
-L linker_options
[Tru64 UNIX] Passes the specified link options to the ld command used
to build the locale.
-m methodfile
[Tru64 UNIX] Specifies the name of a method file that describes which
methods are to be overridden when constructing a locale. The localedef
command reads the method file and uses the entry points when
constructing the locale objects. The codeset methods specified are
also used in parsing the charmap file.
-P tool_path
[Tru64 UNIX] Prepends the specified path to the compiler and linker
commands.
-v [Tru64 UNIX] Runs the command in verbose mode to display information
used for debugging.
-w [Tru64 UNIX] Displays warnings when duplicate definitions are
encountered.
OPERANDS
localename
Identifies the locale and determines where it will be built.
[Tru64 UNIX] Locales can be moved after they are created and the
presence or absence of slash (/) characters in localename does not
indicate whether a locale is later treated as public or private. The
default directory for public locales is /usr/lib/nls/loc, to which,
assuming the appropriate privileges, a locale can be moved after it is
created.
When running the localedef command on other operating systems, you may
have to omit slash (/) characters from localename when creating a
public locale and include them only when creating a private locale. On
these platforms, public locales are automatically created in the
appropriate directory and may be the only locales that system commands
can access.
Note
Because a number of changes have been made to locales to enable
support for the latest version of the Unicode standard (see
Unicode(5)), locales you generate on Tru64 UNIX Version 5.1B and
later may not work under earlier versions of Tru64 UNIX. However,
locales you generate on earlier versions of Tru64 UNIX will work
under Version 5.1B.
DESCRIPTION
The localedef command converts source files that contain definitions of the
locale-dependent information (collation, date-and-time displays, and
character properties) into a run-time format. The command then assigns the
definitions a locale name to be used with commands and functions that set
the locale.
If a locale category source definition contains a copy statement and the
statement names a valid existing locale that is installed in the system,
localedef behaves as if the source definition had contained a valid
category source definition for the named locale.
[Tru64 UNIX] The localedef command can also process a file that specifies
how to build a methods library to be used by character- and string-
conversion functions when they operate in the locale environment. This
library is necessary for locales based on multibyte codesets, which require
conversion methods that are different from the default methods used by C
library routines. A method file has the following format:
METHODS
method entry[package[library_path]]
END METHODS
[Tru64 UNIX] The method file contains the following information:
method
The name of the method.
entry
The C function that implements the method. This function is tailored
to the locale's codeset.
package
The optional package name for the shared library. The package field is
ignored; however, you must specify it if you specify library_path.
library_path
The pathname of the shared-library or loadable object that contains the
entry implementations.
[Tru64 UNIX] The package and library_path fields are optional. If not
specified, these fields default to libc and /usr/shlib/libc.so,
respectively. The localedef command retains the last value specified for
both of these fields, so you need to specify these values only once to
override the default for the entire methods file.
[Tru64 UNIX] The following example of a methods file lists all of the
valid values for the method field in the first column, along with the
default entry, package, and pathname values that are used with single-byte
locales other than the POSIX locale:
METHODS
__mbstopcs "__mbstopcs_sb" "libc" "/usr/shlib/libc.so"
__mbtopc "__mbtopc_sb"
__pcstombs "__pcstombs_sb"
__pctomb "__pctomb_sb"
mblen "__mblen_sb"
mbstowcs "__mbstowcs_sb"
mbtowc "__mbtowc_sb"
wctomb "__wctomb_sb"
wcstombs "__wcstombs_sb"
wcwidth "__wcwidth_latin"
wcswidth "__wcswidth_latin"
fnmatch "__fnmatch_std"
iswctype "__iswctype_std"
localeconv "__localeconv_std"
nl_langinfo "__nl_langinfo_std"
regcomp "__regcomp_std"
regexec "__regexec_std"
regfree "__regfree_std"
rpmatch "__rpmatch_std"
regerror "__regerror_std"
towupper "__towupper_std"
towlower "__towlower_std"
strcoll "__strcoll_std"
strfmon "__strfmon_std"
strftime "__strftime_std"
strptime "__strptime_std"
strxfrm "__strxfrm_std"
wcscoll "__wcscoll_std"
wcsftime "__wcsftime_std"
wcsxfrm "__wcsxfrm_std"
wctype "__wctype_std"
END METHODS
[Tru64 UNIX] If you supply a methods file for your locale, the file must
contain entries for the following methods because, without them, it is not
possible to read the charmap file:
__mbstopcs
__mbtopc
__pcstombs
__pctomb
mblen
mbstowcs
mbtowc
wcstombs
wcswidth
wctomb
wcwidth
[Tru64 UNIX] Entries for methods other than the preceding ones are
optional.
EXIT STATUS
The localedef command returns the following exit values:
0 No errors occurred and the locale was successfully created.
1 Warnings occurred and the locale was successfully created.
2 The locale specification exceeded limits or the coded character set or
sets being used are not supported, and no locale was created.
3 The capability to create new locales is not supported.
>3 Warnings or errors occurred and no output was created.
If an error occurs on execution of the localedef command, it does not
create an output file.
If warnings occur, the command creates an output file only if the -c option
is specified. The following conditions cause warning messages to be
issued:
· A symbolic name not found in the charmap file was used for the
descriptions of the LC_TYPE or LC_COLLATE categories. (For other
categories, this condition is treated as an error.)
· The number of operands to the order keyword exceeds the
COLL_WEIGHTS_MAX limit.
· Optional but unsupported keywords are present in the source input.
ERRORS
[Tru64 UNIX] To review localedef diagnostic messages, enter the following
commands:
% cd /usr/lib/nls/msg/en_US.ISO8859-1
% dspcat localedef.cat | more
EXAMPLES
1. To create a locale called Austin from standard input and to disregard
warnings, enter the following:
localedef -c Austin
2. To create a locale called Austin from Austin.src as source input,
enter the following:
localedef -i Austin.src Austin
ENVIRONMENT VARIABLES
The following environment variables affect execution of the localedef
command. See i18n_intro(5) and l10n_intro(5) for more information.
LANG
Provides a default value for the locale category variables that are not
set.
LC_ALL
If set to a nonempty string value, overrides the values of all locale
category variables and LANG.
LC_CTYPE
Specifies the locale used to interpret byte sequences as characters in,
for example, command parameters. The setting of this variable does not
affect the processing of the input source, for which the command always
uses the POSIX locale.
LC_MESSAGES
Specifies the locale that determines which translations to use, if any
exist, for the command's messages.
NLSPATH
Determines the search path that the command uses to find message
catalogs needed for processing LC_MESSAGES.
