gensprep8

Usage

Overview

gensprep reads filtered RFC 3454 files and compiles their information into a binary form. The resulting file, <name>.icu, can then be read directly by ICU, or used by pkgdata(8) for incorporation into a larger archive or library.

The files read by gensprep are described in the FILES section.

Options

-h, -?, --help

Print help about usage and exit.

-v, --verbose

Display extra informative messages during execution.

-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 ${prefix}/share/icu/78.3/. 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.
