DERB(1) ICU 55.1 Manual DERB(1)NAMEderb - disassemble a resource bundle
SYNOPSISderb [ -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 ...
DESCRIPTIONderb 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 espe‐
cially 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 rep‐
resentation. Characters that cannot be represented in the encod‐
ing 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 direc‐
tory 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 loca‐
tion set when ICU was built if ICU_DATA is not set).
-d, --destdir destination
Set the destination directory to destination. The default des‐
tination 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 exam‐
ple, 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 transforma‐
tion 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 charac‐
ters, expressed as a standard POSIX regular expression: [a-z]|[A-
Z]|[0-9]|_| |+|-|*|/. This is the set which is guaranteed to be avail‐
able regardless of code page.
ENVIRONMENT
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.
