LOCALEDEF(1P)		   POSIX Programmer's Manual		 LOCALEDEF(1P)

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 POSIX.1‐2008, Chap‐
       ter 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 appro‐
       priate 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
       POSIX.1‐2008, 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	 char‐
		 acter symbols and collating element symbols to actual charac‐
		 ter encodings.	 The format of the charmap is described in the
		 Base Definitions volume of POSIX.1‐2008, Section 6.4, Charac‐
		 ter Set Description File.  The application shall ensure  that
		 this  option  is specified if symbolic names (other than col‐
		 lating symbols 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 format of the inputfile is described
		 in  the Base Definitions volume of POSIX.1‐2008, 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 encod‐
		 ing 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
		 POSIX.1‐2008, Chapter 7, Locale for a description of the  use
		 of  this name. If the name contains one or more <slash> char‐
		 acters, 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 pub‐
		 lic. The ability to create public locales in this way 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 POSIX.1‐2008, 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	POSIX.1‐2008,  Section
       6.4, Character Set Description File.  If a locale category source defi‐
       nition contains a copy statement, as defined in	the  Base  Definitions
       volume of POSIX.1‐2008, 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 vari‐
		 ables that are unset or null. (See the Base Definitions  vol‐
		 ume  of POSIX.1‐2008, 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 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  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, the result will be undefined.

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 imple‐
	     mentation, 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.

       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
       POSIX.1‐2008, Section 6.4, Character Set Description File, it is imple‐
       mentation-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	conse‐
       quence,	although several categories can be processed in one execution,
       only categories belonging to the same locale can be processed.)

FUTURE DIRECTIONS
       None.
