genprops(8)

NAME

genprops - compile properties from the Unicode Character Database

SYNOPSIS

genprops [ -h, -?, --help ] [ -v, --verbose ] [ -u, --unicode version ] [ -c, --copyright ] [ -s, --sourcedir source ] [ -d, --destdir destination ] [ suffix ]

DESCRIPTION

genprops reads some of the Unicode Character Database files and compiles their information information into a binary form. The resulting file, icudata.dat, can then be read directly by ICU, or used by pkgdata(8) for incorporation into a larger archive or library.

The files read by genprops are described in the FILES section. If suffix is passed on the command line, the names of these files will actually be changed to include a dash followed by suffix in their basename. For example, the file UnicodeData.txt would be looked for under the name UnicodeData-suffix.txt.

OPTIONS

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

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

-u, --unicode version: Specify which version of Unicode the Unicode Character Database refers to. Defaults to 3.0.0.

-c, --copyright: Include a copyright notice into the binary data.

-s, --sourcedir source: Set the source directory to source. The default source directory is specified by the environment variable ICU_DATA.

-d, --destdir destination: Set the destination directory to destination. The default destination directory is specified by the environment variable ICU_DATA.

ENVIRONMENT

ICU_DATA: Specifies the directory containing ICU data. Defaults to /usr/lib/icu/2.1/. 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.

FILES

The following files are read by genprops and are looked for in the source directory.

UnicodeData.txt: The main file in the Unicode Character Database. Contains character properties, combining classes information, decompositions, names, etc....

BidiMirroring.txt: Properties for substituting characters in an implementation of bidirectional mirroring.

SpecialCasing.txt: List of properties required for full case mapping.

CaseFolding.txt: Mapping from characters to their case-folded forms. (Note: this file is derived from UnicodeData.txt and SpecialCasing.txt when generated by the Unicode Consortium.)
