NAME

       derb - disassemble a resource bundle

SYNOPSIS

       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

       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

       -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 file.

       -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 file.

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

       -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 ICU_DATA.

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

CAVEATS

       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.

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/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.
