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/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.
