.TH WRC 1 "July 05, 2000" "Version 1.1.6" "Wine Resource Compiler"
.SH NAME
wrc \- Wine Resource Compiler
.SH SYNOPSIS
.BI "wrc " "[options] " "[inputfile]"
.SH DESCRIPTION
.B wrc
compiles resources from
.I inputfile
into win16 and win32 compatible
binary format.
.B wrc
outputs the binary data either in a standard \fB.res\fR formatted binary
file, or an assembly file.
.B wrc
is also capable of reading \fB.res\fR formatted files and convert them
into an assembly file.
.PP
The source\-file is preprocessed with a builtin ANSI\-C compatible
preprocessor before the resources are compiled. See \fBPREPROCESSOR\fR
below.
.PP
.B wrc
takes only one \fBinputfile\fR as argument. The \fBinputfile\fR has
extension \fB.rc\fR for resources in source form and \fB.res\fR for
binary resources. The resources are read from standard input if no
inputfile is given. If the outputfile is not specified with \fI-o\fR,
then \fBwrc\fR will write the output to \fBinputfile.{s,h,res}\fR
with \fB.rc\fR stripped, depending on the mode of compilation.
The outputfile is named \fBwrc.tab.{s,h,res}\fR if no inputfile was
given.
.SH OPTIONS
.TP
.I \-a n
Win16 only; set the alignment between resources n.  The alignment must
be a power of 2. The default is 4.
.TP
.I \-A
Obsolete; include code in the assembly output to auto register resources
by calling a special wine function (only with gcc 2.7 and better).
.TP
.I \-b
Create an assembly file from a binary \fB.res\fR file.
.TP
.I \-B x
Win32 only; set output byte\-ordering, where \fIx\fR is one of n[ative],
l[ittle] or b[ig].  Only resource in source-form can be reorderd. Native
ordering depends on the system on which \fBwrc\fR was built. You can see
the native ordering by typing \fI\"wrc \-?\"\fR.
.TP
.I \-c
Add 'const' prefix to C constants when writing header files.
.TP
.I \-C cp
Set the resource's codepage to \fIcp\fR. Default codepage is 0.
.TP
.I \-d n
Set debug level to \fIn\fR. 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.
.TP
.I \-D id[=val]
Define preprocessor identifier \fIid\fR to (optionally) value \fIval\fR.
See also
.B PREPROCESSOR
below.
.TP
.I \-e
Win16 only; disable recognition of win32 keywords in 16bit compile.
Normally, all keywords are recognized in win16 compilation mode. Use
this switch if old sources use win32 reserved names as resource names.
.TP
.I \-E
Preprocess only. The output is written to standard output if no
outputfile was selected. The output is compatible with what gcc would
generate.
.TP
.I \-g
Add symbols to the global C namespace. This makes all symbols available
for linking by other modules.
.TP
.I \-h
Generate a \fB.h\fR header-file. The resource tables are described by
extern declarations.
.TP
.I \-H file
Same as \fI\-h\fR but written to \fIfile\fR.
.TP
.I \-I path
Add \fIpath\fR to include search directories. \fIPath\fR may contain
multiple directories, separated with ':'. It is allowed to specify
\fI\-I\fR multiple times. Include files are searched in the order in
with the \fI\-I\fR options were specified.
.br
The search is compatible with gcc, in which '<>' quoted filenames are
searched exclusively via the \fI\-I\fR 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.
.TP
.I \-l lan
Set default language to \fIlan\fR. Default is the neutral language 0
(i.e. "LANGUAGE 0, 0").
.TP
.I \-L
Leave case of embedded filenames as is. All filenames are converted to
lower case before they are attemped to be opened without this option.
.TP
.I \-m
Do not remap numerical resource type-IDs onto standard resources. This will
cause all numerical resource type\-IDs to be treated as user\-type resources
and will not be checked nor byte\-reversed. Without this option, resources
with, for example, type\-ID 2 are parsed as bitmaps and other type\-IDs will
map onto their respective standard type.
Use this option with caution because it can create problems when compiling for,
for example, big\-endian platforms. The \fI\-m\fR option is usefull for
source\-files that contain overlapping type\-IDs, or when the format of the
resource is not 100% compliant.
.TP
.I \-n
Do not generate an assembly outputfile (suppress generation of \fB.s\fR
file). Usefull if you are interested in a header file only.
.TP
.I \-N
Do not preprocess the input. This will most certainly result in
compilation failure, unless you have preprocessed the source with
another preprocessor before passing it to \fBwrc\fR.
.TP
.I \-o file
Write output to \fIfile\fR. Default is \fBinputfile.{res,s,h}\fR
with \fB.rc\fR stripped or \fBwrc.tab.{s,h,res}\fR, depending on the
compilation mode.
.TP
.I \-p prefix
Prefix all generated names with \fIprefix\fR. This is only relevant for
names in the assembly code and header file. Resource names are not
affected.
.TP
.I \-r
Create binary \fB.res\fR file (compile only).
.TP
.I \-s
Add structure with win32/16 (PE/NE) resource directory to outputfile.
This directory is always in native byteorder.
.TP
.I \-t
Obsolete; generate indirect loadable resource tables.
.TP
.I \-T
Obsolete; generate only indirect loadable resources tables.
.TP
.I \-V
Print version end exit.
.TP
.I \-w 16|32
Select win16 or win32 output. Default is win32.
.TP
.I \-W
Enable pedantic warnings. Notably redefinition of #define statements can
be discovered with this option.
.SH PREPROCESSOR
The preprocessor is ANSI\-C compatible with some extensions of the gcc
preprocessor. 
.PP
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).
.PP
The preprocessor default sets several defines:
.br
RC_INVOKED      set to 1
.br
__WRC__         Major version of wrc
.br
__WRC_MINOR__   Minor version of wrc
.br
__WRC_MICRO__   Patch level
.br
__WRC_PATCH__   Same as __WRC_MICRO__
.PP
Win32 compilation mode also sets __WIN32__ to 1 and __FLAT__ to 1.
.PP
Special macros __FILE__, __LINE__, __TIME__ and __DATE__ are also
recognized and expand to their respective equivalent.
.SH AUTHORS
.B wrc
was written by Bertho A. Stultiens and is a nearly complete rewrite of
the first wine resource compiler (1994) by Martin von Loewis.
Additional resource\-types were contributed Ulrich Czekalla and Albert
den Haan. Bugfixes have been contributed by many wine developpers.
.SH BUGS
\- The preprocessor recognizes variable argument macros, but does not
expanded them correctly
.br
\- Codepage/UNICODE translations are not/not correct implemented
.br
\- Default memory options should differ between win16 and win32.
.PP
There is no support for:
.br
\- RT_DLGINCLUDE, RT_VXD, RT_PLUGPLAY and RT_HTML (unknown format)
.br
\- PUSHBOX control is unsupported due to lack of original functionality.
.PP
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.
