The source-file is preprocessed with a builtin ANSI-C compatible preprocessor before the resources are compiled. See PREPROCESSOR below.

wrc takes only one inputfile as argument. The resources are read from standard input if no inputfile is given. If the output file is not specified with -o, then wrc will write the output to inputfile.res with .rc stripped, or to wrc.tab.res if no inputfile was given.

--debug=nn

Set debug level to nn. The value is a bitmask consisting of 1=verbose, 2=dump internals, 4=resource parser trace, 8=preprocessor messages, 16=preprocessor scanner and 32=preprocessor parser trace.

--endianess=e

Win32 only; set output byte-ordering, where e is one of n[ative], l[ittle] or b[ig]. Only resources in source-form can be reorderd. Native ordering depends on the system on which wrc was built. You can see the native ordering by typing wrc -h.

-D, --define=id[=val]

Define preprocessor identifier id to (optionally) value val. See also PREPROCESSOR below.

-E

Preprocess only. The output is written to standard output if no outputfile was selected. The output is compatible with what gcc would generate.

-F, --target

Ignored for compatibility with windres.

-h, --help

Prints a summary message and exits.

-i, --input=file

The name of the input file. If this option is not used, then wrc will use the first non-option argument as the input file name. If there are no non-option arguments, then wrc will read from standard input.

-I, --include-dir=file

Add path to include search directories. Path may contain multiple directories, separated with ':'. It is allowed to specify -I multiple times. Include files are searched in the order in with the -I options were specified. The search is compatible with gcc, in which '<>' quoted filenames are searched exclusively via the -I set path, whereas the '""' quoted filenames are first tried to be opened in the current directory. Also resource statements with file references are located in the same way.

-J, --input-format=format

Sets the input format. Valid options are 'rc' or 'rc16'. Setting the input to 'rc16' disables the recognition of win32 keywords.

-l, --language=lan

Set default language to lan. Default is the neutral language 0 (i.e. "LANGUAGE 0, 0").

--nostdinc

Do not search the standard include path, look for include files only in the directories explicitly specified with the -I option.

--no-use-temp-file

Ignored for compatibility with windres.

-o, -fo, --output=file

Write output to file. Default is inputfile.res with .rc stripped or wrc.tab.res if input is read from standard input.

-O, --output-format=format

Sets the output format. The supported formats are 'res' and 'res16'. If this option is not specified, format defaults to 'res'.

--pedantic

Enable pedantic warnings. Notably redefinition of #define statements can be discovered with this option.

-r

Ignored for compatibility with rc.

--preprocessor=program

This option may be used to specify the preprocessor to use, including any leading arguments. If not specified, wrc uses its builtin processor. To disable preprocessing, use --preprocessor=cat.

-U, --undefine=id

Undefine preprocessor identifier id. Please note that only macros defined up to this point are undefined by this command. However, these include the special macros defined automatically by wrc. See also PREPROCESSOR below.

--use-temp-file

Ignored for compatibility with windres.

-v, --verbose

Turns on verbose mode (equivalent to -d 1).

--version

Print version end exit.

The preprocessor recognizes these directives: #include, #define (both simple and macro), #undef, #if, #ifdef, #ifndef, #elif, #else, #endif, #error, #warning, #line, # (both null- and line-directive), #pragma (ignored), #ident (ignored).

The preprocessor sets by default several defines: RC_INVOKED set to 1 __WRC__ Major version of wrc __WRC_MINOR__ Minor version of wrc __WRC_PATCHLEVEL__ Patch level

Win32 compilation mode also sets __WIN32__ to 1 and __FLAT__ to 1.

Special macros __FILE__, __LINE__, __TIME__ and __DATE__ are also recognized and expand to their respective equivalent.

Example:

1 RCDATA DISCARDABLE LANGUAGE 1, 0 VERSION 312 CHARACTERISTICS 876 { 1, 2, 3, 4, 5, "and whatever more data you want" '00 01 02 03 04 05 06 07 08' }

There is no support for: - RT_DLGINCLUDE, RT_VXD, RT_PLUGPLAY and RT_HTML (unknown format) - PUSHBOX control is unsupported due to lack of original functionality.

Fonts are parsed and generated, but there is no support for the generation of the FONTDIR yet. The user must supply the FONTDIR resource in the source to match the FONT resources.
