gensprep (8) Linux Manual Page
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,–sourcedirsource- Set the source directory to source. The default source directory is specified by the environment variable
ICU_DATA. -d,–destdirdestination- 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/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 ifICU_DATAis set.
Files
The following files are read by gensprep and are looked for in the source /misc for rfc3454_*.txt files and in source /unidata for NormalizationCorrections.txt.
