derb - disassemble a resource bundle
derb [ -h, -?, --help ] [ -V, --version ] [ -v, --verbose ] [ -e, --encoding encoding ] [ --bom ] [ -l, --locale locale ] [ -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 bun- dle 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 either the value of the -l, --locale option, or the same as 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. -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 speci- fied 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 /usr/share/icu/50.1.2/. 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.
