NAME         top

       derb - disassemble a resource bundle

SYNOPSIS         top

       derb [ -h, -?, --help ] [ -V, --version ] [ -v, --verbose ] [ -e,
       --encoding encoding ] [ --bom ] [ -t, --truncate [ size ] ] [ -s,
       --sourcedir source ] [ -d, --destdir destination ] [ -i,
       --icudatadir directory ] [ -c, --to-stdout ] bundle ...

DESCRIPTION         top

       derb reads the compiled resource bundle files passed on the
       command line and write them back in text form.  The resulting
       text files have a .txt extension while compiled resource bundle
       source files typically have a .res extension.

       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.res for Japanese (Japan) data, or root.res for the
       root bundle.  This is especially important for derb since the
       locale name is not accessible directly from the compiled resource
       bundle, and to know which locale to ask for when opening the
       bundle.  derb will produce a file whose base name is the base
       name of the compiled resource file itself.  If the --to-stdout,
       -c option is used, however, the text will be written on the
       standard output.

OPTIONS         top

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

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

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

       -A, --suppressAliases
              Don't follow aliases when producing output.

       -e, --encoding encoding
              Set the encoding used to write output files to encoding.
              The default encoding is the invariant (subset of ASCII or
              EBCDIC) codepage for the system (see section INVARIANT
              CHARACTERS).  The choice of the encoding does not affect
              the data, just their representation. Characters that
              cannot be represented in the encoding will be represented
              using \uhhhh escape sequences.

       --bom  Write a byte order mark (BOM) at the beginning of the

       -l, --locale locale
              Set the locale for the resource bundle, which is used both
              in the generated text and as the base name of the output

       -t, --truncate [ size ]
              Truncate individual resources (strings or binary data) to
              size bytes. The default if size is not specified is 80

       -s, --sourcedir source
              Set the source directory to source.  The default source
              directory is the current directory.  If - is passed for
              source, then the bundle will be looked for in its default
              location, specified by the ICU_DATA environment variable
              (or defaulting to 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

       -c, --to-stdout
              Write the disassembled bundle on standard output instead
              of into a file.

CAVEATS         top

       When the option --bom is used, the character U+FEFF is written in
       the destination encoding regardless of whether it is a Unicode
       transformation format (UTF) or not.  This option should only be
       used with an UTF encoding, as byte order marks are not meaningful
       for other encodings.


       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         top

              Specifies the directory containing ICU data. Defaults to
              ${prefix}/share/icu/70.0.1/.  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.
