GENRB(1)                        ICU 69.1 Manual                       GENRB(1)

NAME
       genrb - compile a resource bundle

SYNOPSIS
       genrb [ -h, -?, --help ] [ -V, --version ] [ -v, --verbose ] [ -e,
       --encoding encoding ] [ -j, --write-java [ encoding ] ] [ -s,
       --sourcedir source ] [ -d, --destdir destination ] [ -i, --icudatadir
       directory ] bundle ...

DESCRIPTION
       genrb converts the resource bundle source files passed on the command
       line to their binary form or to a Java source file for use with ICU4J.
       The resulting binary files have a .res extension while resource bundle
       source files typically have a .txt extension. Java source files have a
       java extension and follow the ICU4J naming conventions.

       It is customary to name the resource bundles by their locale name, i.e.
       to use a local identifier for the bundle filename, e.g.  ja_JP.txt for
       Japanese (Japan) data, or root.txt for the root bundle.  In any case,
       genrb will produce a file whose base name is the name of the locale
       found in the resource file, not the base name of the resource file
       itself.

       The binary files can be read directly by ICU, or used by pkgdata(1) for
       incorporation into a larger archive or library.

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

       -V, --version
              Print the version of genrb and exit.

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

       -e, --encoding encoding
              Set the encoding used to read input files to encoding.  The
              default encoding is the invariant (subset of ASCII or EBCDIC)
              codepage for the system (see section INVARIANT CHARACTERS).  The
              encodings UTF-8, UTF-16BE, and UTF-16LE are automatically
              detected if a byte order mark (BOM) is present.

       -j, --write-java [ encoding ]
              Generate a Java source code for use with ICU4J. An optional
              encoding for the Java file can be given.

       -s, --sourcedir source
              Set the source directory to source.  The default source
              directory is specified by the environment variable ICU_DATA, or
              the location set when ICU was built if ICU_DATA is not set.

       -d, --destdir destination
              Set the destination directory to destination.  The default
              destination directory is specified by the environment variable
              ICU_DATA or is the location set when ICU was built if ICU_DATA
              is not set.

       -i, --icudatadir directory
              Look for any necessary ICU data files in directory.  For
              example, when processing collation overrides, the file
              ucadata.dat must be located.  The default ICU data directory is
              specified by the environment variable ICU_DATA.

INVARIANT CHARACTERS
       The invariant character set consists of the following set of
       characters, expressed as a standard POSIX regular expression:
       [a-z]|[A-Z]|[0-9]|_| |+|-|*|/.  This is the set which is guaranteed to
       be available regardless of code page.

ENVIRONMENT
       ICU_DATA  Specifies the directory containing ICU data. Defaults to
                 ${prefix}/share/icu/69.1/.  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.
