MKLOCALE(1)

NAME
mklocale - make LC_CTYPE locale files

SYNOPSIS
mklocale [-d] [-t type] < source > language/LC_CTYPE
mklocale [-d] [-t type] -o language/LC_CTYPE source

DESCRIPTION
The mklocale utility reads an LC_CTYPE source file from standard input and produces an LC_CTYPE binary file on standard output suitable for placement in /usr/share/locale/<language>/LC_CTYPE.

The format of source is quite simple. It consists of a series of lines which start with a keyword and have associated data following. C style comments are used to place comments in the file.

Following options are available:

-d  Turns on debugging messages.

-o  Specify output file.

-t  Generate output in new-style LC_{MONETARY,NUMERIC,TIME,MESSAGES} locale-db format.

Besides the keywords which will be listed below, the following are valid tokens in source:

RUNE
    A RUNE may be any of the following:

    'x' The ASCII character x.

    '\x'
        The ANSI C character \x where \x is one of \a, \b, \f, \n, \r, \t, or \v.

    0x[0-9a-f]+
        A hexadecimal number representing a rune code.

    0[0-7]*
        An octal number representing a rune code.

    [1-9][0-9]*
        A decimal number representing a rune code.

STRING
    A string enclosed in double quotes (").

THRU
    Either ... or -. Used to indicate ranges.

literal
    The follow characters are taken literally:

    <([ Used to start a mapping. All are equivalent.

    >)] Used to end a mapping. All are equivalent.

    :   Used as a delimiter in mappings.

Key words which should only appear once are:

ENCODING
    Followed by a STRING which indicates the encoding mechanism to be used for this locale. The current encodings are:

    NONE
        No translation and the default.

    UTF2
        Universal character set Transformation Format adopted from Plan 9 from Bell Labs.

    EUC EUC encoding as used by several vendors of UNIX systems.

VARIABLE
    This keyword must be followed by a single tab or space character, after which encoding specific data is placed. Currently only the EUC encoding requires variable data.

INVALID
    A single RUNE follows and is used as the invalid rune for this locale.

The following keywords may appear multiple times and have the following format for data:

<RUNE1 RUNE2>
    RUNE1 is mapped to RUNE2.

<RUNE1 THRU RUNEn: RUNE2>
    Runes RUNE1 through RUNEn are mapped to RUNE2 through RUNE2 + n-1.

MAPLOWER
    Defines the tolower mappings. RUNE2 is the lower case representation of RUNE1.

MAPUPPER
    Defines the toupper mappings. RUNE2 is the upper case representation of RUNE1.

TODIGIT
    Defines a map from runes to their digit value. RUNE2 is the integer value represented by RUNE1. For example, the ASCII character ‘0’ would map to the decimal value 0. On NetBSD, this information has never been used until now. Only values up to 255 are allowed, and mapping to 256 and above is silently ignored.

The following keywords may appear multiple times and have the following format for data:

RUNE
    This rune has the property defined by the keyword.

RUNE1 THRU RUNEn
    All the runes between and including RUNE1 and RUNEn have the property defined by the keyword.

ALPHA
    Defines runes which are alphabetic, printable, and graphic.

CONTROL
    Defines runes which are control characters.

DIGIT
    Defines runes which are decimal digits, printable, and graphic.

GRAPH
    Defines runes which are graphic and printable.

LOWER
    Defines runes which are lower case, printable, and graphic.

PUNCT
    Defines runes which are punctuation, printable, and graphic.

SPACE
    Defines runes which are spaces.

UPPER
    Defines runes which are upper case, printable, and graphic.

XDIGIT
    Defines runes which are hexadecimal digits, printable, and graphic.

BLANK
    Defines runes which are blank.

PRINT
    Defines runes which are printable.

IDEOGRAM
    Defines runes which are ideograms, printable, and graphic.

SPECIAL
    Defines runes which are special characters, printable, and graphic.

PHONOGRAM
    Defines runes which are phonograms, printable, and graphic.

SWIDTHn
    Defines runes with specific glyph width. n takes 0 to 3.

CHARSET
    Controls character set for subsequent runes.

HISTORY
The mklocale utility first appeared in 4.4BSD.

BUGS
The mklocale utility is overly simplistic.

We should switch to localedef and its file format, which is more standard.
