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/72.1/.  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.
