DERB(1) ICU 72.1 Manual DERB(1)

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/72.1/. 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.
