NAME

6       derb - disassemble a resource bundle
7

SYNOPSIS

9       derb [ -h, -?, --help ] [ -V, --version ] [ -v, --verbose ] [ -e, --en‐
10       coding encoding ] [ --bom  ]  [  -t,  --truncate  [  size  ]  ]  [  -s,
11       --sourcedir  source  ] [ -d, --destdir destination ] [ -i, --icudatadir
12       directory ] [ -c, --to-stdout ] bundle ...
13

DESCRIPTION

15       derb reads the compiled resource bundle files  passed  on  the  command
16       line and write them back in text form.  The resulting text files have a
17       .txt extension while compiled resource bundle  source  files  typically
18       have a .res extension.
19
20       It is customary to name the resource bundles by their locale name, i.e.
21       to use a local identifier for the bundle filename, e.g.  ja_JP.res  for
22       Japanese  (Japan) data, or root.res for the root bundle.  This is espe‐
23       cially important for derb since the locale name is not  accessible  di‐
24       rectly  from  the compiled resource bundle, and to know which locale to
25       ask for when opening the bundle.  derb will produce a file  whose  base
26       name  is  the  base  name of the compiled resource file itself.  If the
27       --to-stdout, -c option is used, however, the text will  be  written  on
28       the standard output.

OPTIONS

31       -h, -?, --help
32              Print help about usage and exit.
33
34       -V, --version
35              Print the version of derb and exit.
36
37       -v, --verbose
38              Display extra informative messages during execution.
39
40       -A, --suppressAliases
41              Don't follow aliases when producing output.
42
43       -e, --encoding encoding
44              Set  the  encoding  used to write output files to encoding.  The
45              default encoding is the invariant (subset of  ASCII  or  EBCDIC)
46              codepage for the system (see section INVARIANT CHARACTERS).  The
47              choice of the encoding does not affect the data, just their rep‐
48              resentation. Characters that cannot be represented in the encod‐
49              ing will be represented using \uhhhh escape sequences.
50
51       --bom  Write a byte order mark (BOM) at the beginning of the file.
52
53       -l, --locale locale
54              Set the locale for the resource bundle, which is  used  both  in
55              the generated text and as the base name of the output file.
56
57       -t, --truncate [ size ]
58              Truncate  individual  resources (strings or binary data) to size
59              bytes. The default if size is not specified is 80 bytes.
60
61       -s, --sourcedir source
62              Set the source directory to source.  The default  source  direc‐
63              tory  is the current directory.  If - is passed for source, then
64              the bundle will be looked for in its default location, specified
65              by the ICU_DATA environment variable (or defaulting to the loca‐
66              tion set when ICU was built if ICU_DATA is not set).
67
68       -d, --destdir destination
69              Set the destination directory to destination.  The default  des‐
70              tination  directory  is  specified  by  the environment variable
71              ICU_DATA or is the location set when ICU was built  if  ICU_DATA
72              is not set.
73
74       -i, --icudatadir directory
75              Look  for  any necessary ICU data files in directory.  For exam‐
76              ple, when processing collation overrides, the  file  ucadata.dat
77              must be located.  The default ICU data directory is specified by
78              the environment variable ICU_DATA.
79
80       -c, --to-stdout
81              Write the disassembled bundle on standard output instead of into
82              a file.
83

CAVEATS

85       When  the  option --bom is used, the character U+FEFF is written in the
86       destination encoding regardless of whether it is a Unicode  transforma‐
87       tion  format (UTF) or not.  This option should only be used with an UTF
88       encoding, as byte order marks are not meaningful for other encodings.
89

INVARIANT CHARACTERS

91       The invariant character set consists of the following  set  of  charac‐
92       ters,  expressed  as  a  standard  POSIX  regular expression: [a-z]|[A-
93       Z]|[0-9]|_| |+|-|*|/.  This is the set which is guaranteed to be avail‐
94       able regardless of code page.
95

ENVIRONMENT

97       ICU_DATA  Specifies  the  directory  containing  ICU  data. Defaults to
98                 /usr/share/icu/73.2/.  Some tools in ICU depend on the  pres‐
99                 ence of the trailing slash. It is thus important to make sure
100                 that it is present if ICU_DATA is set.
