genbrk - Man Page

Compiles ICU break iteration rules source files into binary data files


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


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.


-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.


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.



Specifies the directory containing ICU data. Defaults to /usr/share/icu/74.2/. 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.
