GENBRK(1)                   ICU 76.0.1 Manual                   GENBRK(1)

NAME         top

       genbrk - Compiles ICU break iteration rules source files into
       binary data files

SYNOPSIS         top

       genbrk [ -h, -?, --help ] [ -V, --version ] [ -c, --copyright ] [
       -v, --verbose ] [ -d, --destdir destination ] [ -i, --icudatadir
       directory ] -r, --rules rule-file -o, --out output-file

DESCRIPTION         top

       genbrk reads the break (boundary) rule source code from rule-file
       and creates a break iteration data file. Normally this data file
       has the .brk extension.

       The details of the rule syntax can be found in ICU's User Guide.

OPTIONS         top

       -h, -?, --help
              Print help about usage and exit.

       -V, --version
              Print the version of genbrk and exit.

       -c, --copyright
              Embeds the standard ICU copyright into the output-file.

       -v, --verbose
              Display extra informative messages during execution.

       -d, --destdir destination
              Set the destination directory of the output-file to
              destination.

       -i, --icudatadir directory
              Look for any necessary ICU data files in directory.  For
              example, the file pnames.icu must be located when ICU's
              data is not built as a shared library.  The default ICU
              data directory is specified by the environment variable
              ICU_DATA.  Most configurations of ICU do not require this
              argument.

       -r, --rules rule-file
              The source file to read.

       -o, --out output-file
              The output data file to write.

CAVEATS         top

       When the rule-file contains a byte order mark (BOM) at the
       beginning of the file, which is the Unicode character U+FEFF, then
       the rule-file is interpreted as Unicode. Without the BOM, the file
       is interpreted in the current operating system default codepage.
       In order to eliminate any ambiguity of the encoding for how the
       rule-file was written, it is recommended that you write this file
       in UTF-8 with the BOM.

ENVIRONMENT         top

       ICU_DATA
              Specifies the directory containing ICU data. Defaults to
              ${prefix}/share/icu/76.0.1/.  Some tools in ICU depend on
              the presence of the trailing slash. It is thus important to
              make sure that it is present if ICU_DATA is set.
