COLLDEF(1)			   BSD General Commands Manual			       COLLDEF(1)

NAME
     colldef -- convert collation sequence source definition

SYNOPSIS
     colldef [-I map_dir] [-o out_file] [filename]

DESCRIPTION
     The colldef utility converts a collation sequence source definition into a format usable by
     the strxfrm() and strcoll() functions.  It is used to define the many ways in which strings
     can be ordered and collated.  strxfrm() transforms its first argument and places the result
     in its second argument.  The transformed string is such that it can be correctly ordered
     with other transformed strings by using strcmp(), strncmp(), or memcmp().	strcoll() trans-
     forms its arguments and does a comparison.

     The colldef utility reads the collation sequence source definition from the standard input
     and stores the converted definition in filename.  The output file produced contains the
     database with collating sequence information in a form usable by system commands and rou-
     tines.

     Options list:

     -I map_dir
	   This option set directory name where charmap files can be found, current directory by
	   default.

     -o out_file
	   This option set output file name, LC_COLLATE by default.

     The collation sequence definition specifies a set of collating elements and the rules defin-
     ing how strings containing these should be ordered.  This is most useful for different lan-
     guage definitions.

     The specification file can consist of three statements: charmap, substitute and order.

     Of these, only the order statement is required.  When charmap or substitute is supplied,
     these statements must be ordered as above.  Any statements after the order statement are
     ignored.

     Lines in the specification file beginning with a # are treated as comments and are ignored.
     Blank lines are also ignored.

     charmap charmapfile

     charmap defines where a mapping of the character and collating element symbols to the actual
     character encoding can be found.

     The format of charmapfile is shown below.	Symbol names are separated from their values by
     TAB or SPACE characters. symbol-value can be specified in a hexadecimal (\x??) or octal
     (\???)  representation, and can be only one character in length.

     symbol-name1 symbol-value1
     symbol-name2 symbol-value2
     ...

     The charmap statement is optional.

     substitute symbol with "repl_string"

     The substitute statement substitutes the character symbol with the string repl_string.  Sym-
     bol names cannot be specified in repl_string field.  The substitute statement is optional.

     order order_list

     order_list is a list of symbols, separated by semi colons, that defines the collating
     sequence.	The special symbol ... specifies, in a short-hand form, symbols that are sequen-
     tial in machine code order.

     An order list element can be represented in any one of the following ways:

     o	 The symbol itself (for example, a for the lower-case letter a)

     o	 The symbol in octal representation (for example, \141 for the letter a)

     o	 The symbol in hexadecimal representation (for example, \x61 for the letter a)

     o	 The symbol name as defined in the charmap file (for example, <letterA> for letterA \023
	 record in charmapfile).  If character map name have > character, it must be escaped as
	 />, single / must be escaped as //.

     o	 Symbols \a, \b, \f, \n, \r, \v are permitted in its usual C-language meaning

     o	 The symbol chain (for example: abc, <letterA><letterB>c, \xf1b\xf2)

     o	 The symbol range (for example, a;...;z)

     o	 Comma-separated symbols, ranges and chains enclosed in parenthesis (for example ( sym1,
	 sym2, ... )) are assigned the same primary ordering but different secondary ordering.

     o	 Comma-separated symbols, ranges and chains enclosed in curly brackets (for example {
	 sym1, sym2, ... }) are assigned the same primary ordering only.

     The backslash character \ is used for continuation.  In this case, no characters are permit-
     ted after the backslash character.

DIAGNOSTICS
     The colldef utility exits with the following values:

     0	     No errors were found and the output was successfully created.

     !=0     Errors were found.
