DERB(1) ICU 76.0.1 Manual DERB(1)
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 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.
ICU_DATA
Specifies the directory containing ICU data. Defaults to
${prefix}/share/icu/76.0.1/. 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.
