gensprep(8) ICU 70.1 Manual gensprep(8)

NAME
gensprep - compile StringPrep data from files filtered by filterRFC3454.pl

SYNOPSIS
gensprep [ -h, -?, --help ] [ -v, --verbose ] [ -c, --copyright ] [ -s, --sourcedir source
] [ -d, --destdir destination ]

DESCRIPTION
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 ${pre-
fix}/share/icu/70.1/. 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.
