NAME

genxlt - Generates a codeset conversion table  

SYNOPSIS

genxlt [-f outputfile] [inputfile]


 

OPTIONS

Specifies that the generated version of the codeset conversion table be placed in the file specified by outputfile.
 

DESCRIPTION

The iconv subsystem can use either an algorithmic or a table converter to convert data from one codeset to another. The genxlt command creates a table converter to be used by the iconv subsystem.

The genxlt command reads a source codeset conversion table file from inputfile and writes the compiled version to outputfile. If inputfile is not specified, standard input is used. If outputfile is not specified, standard output is used. The source codeset conversion table file contains directives that are acted upon by the genxlt command to produce the compiled version.

The format of a translation source file is as follows: Lines whose initial nonwhite-space character is the # (number sign) are treated as comment lines. Null lines and lines consisting only of white-space characters are treated as comment lines. Noncomment lines have to be of the following form: source target comment

If source is found in the source codeset conversion table file multiple times, the last entry is used in the compilation of the translation table.

The source and target arguments must be in the range of 0x00 through 0xff, inclusive; this restricts the table to 8-bit codesets. The conversion table must define all of the 256 possible source values; otherwise, processing the table results in an error.

The following is an excerpt of a codeset conversion table:

0x80 0xc7 C cedilla 0x81 0xfc u diaeresis 0x82 0xe9 e acute 0x83 0xe2 a circumflex 0x84 0xe4 a diaeresis 0x85 0x40 a grave

The name of the file generated by the genxlt command must use the following naming convention in order for the iconv subsystem to recognize the file as a valid converter.

fromcode: "ISO8859-1-GL" tocode: "ISO8859-1" conversion table file: "ISO8859-1-GL_ISO8859-1"

The conversion table file name is formed by concatenating the tocode file name onto the fromcode file name, with an underscore character between the two. The compiled conversion table must reside in the /usr/lib/nls/loc/iconvTable directory or, if the LOCPATH variable is defined, in an iconvTable directory subordinate to the LOCPATH directory. Otherwise, the iconv command does not find the table.

Note

The LOCPATH variable also overrides the default search path (/usr/lib/nls/loc) that is used to find locales. If this variable is defined, it must therefore specify a search path that application and system software can use to find both locales and converters. The LOCPATH variable is not defined by any standard, so use of the variable should be limited to testing locales or converters under development.


 

EXIT STATUS

If successful, the genxlt command exits with a value of 0 (zero). If an unknown flag is detected, or the specified input file or output file cannot be opened, the genxlt command is unsuccessful and exits with a value of 1. If a syntax error is detected in the input stream, the genxlt command will exit immediately with a value of 2, and write to standard error the line numbers where the syntax error occurred.
