derb - disassemble a resource bundle


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 ...


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.


-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.


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


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.


ICU_DATA Specifies the directory containing ICU data. Defaults to
${prefix}/share/icu/55.1/. 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.
