.TH WRC 1 "August 24, 2000" "Version 1.1.8" "Wine Resource Compiler"
.SH NAME
wrc \- Wine Resource Compiler
.SH SYNOPSIS
.BI "wrc " "[options] " "[inputfile]"
.SH DESCRIPTION
.B wrc
compiles resources from \fBinputfile\fR
into win16 and win32 compatible binary format.
.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 resources are read from 
standard input if no inputfile is given. If the output file is not 
specified with \fI-o\fR, then \fBwrc\fR will write the output to 
\fBinputfile.res\fR with \fB.rc\fR stripped, or to \fBwrc.tab.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 \-B x
Win32 only; set output byte\-ordering, where \fIx\fR 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 \fBwrc\fR was built. You can see
the native ordering by typing \fIwrc \-?\fR.
.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 \-h
Prints a summary message and exits.
.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 \-J
Do not search the standard include path, look for include files only
in the directories explicitly specified with the \fI\-I\fR option.
.TP
.I \-l lan
Set default language to \fIlan\fR. Default is the neutral language 0
(i.e. "LANGUAGE 0, 0").
.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 \-o file
Write output to \fIfile\fR. Default is \fBinputfile.res\fR
with \fB.rc\fR stripped or \fBwrc.tab.res\fR if input is read
from standard input.
.TP
.I \-O format
Sets the output format. The only supported \fformat\fR is 'res', which
is also the default format if this option is not specified. The option
exists mainly for compatibility with \fBwindres\fR.
.TP
.I \-P program
This option may be used to specify the preprocessor to use, including any 
leading arguments. If not specified, \fBwrc\fR uses its builtin processor.
To disable preprocessing, use \fB-P cat\fR.
.TP
.I \-v
Turns on verbose mode (equivalent to -d 1).
.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 "LANGUAGE SUPPORT"
Language, version and characteristics can be bound to all resource types that
have inline data, such as RCDATA. This is an extension to MS' resource
compiler, which lacks this support completely. Only VERSIONINFO cannot have
version and characteristics attached, but languages are propagated properly if
you declare it correctly before the VERSIONINFO resource starts.
.PP
Example:
.PP
1 RCDATA DISCARDABLE
.br
LANGUAGE 1, 0
.br
VERSION 312
.br
CHARACTERISTICS 876
.br
{
.br
	1, 2, 3, 4, 5, "and whatever more data you want"
.br
	'00 01 02 03 04 05 06 07 08'
.br
}
.SH NE/PE RESOURCE DIRECTORY GENERATION
A windows executable has a table/directory of resources available in that
module. Wrc will generate this directory with the '-s' option and place it
in the assembly output. 
.PP
The layout of the PE directory should be exactly like the executable file.
The NE directory layout _DIFFERS_ from the real NE executable in such way
that all offsets to actual resource data are relative to the NE directory and
_NOT_ the beginning of the file.
.SH "ERROR REPORTING"
All errors and warnings are written to standard error and report:
.br
\fIfilename\fR:\fIline\-number\fR:\fIcharacter\-pos\fR:\fI{Error,Warning}\fR:\fI<message>\fR
.br
The character\-position is always at the next token. I.e. the error
or warning happened before. The line\-number suffers from the same
problem if the error occurred at the last token of the previous line.
The line\-number will be several lines off when the error was followed
by several empry lines. See also \fBBUGS\fR.
.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
\- Error reporting should be more to the point (and verbose)
.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.
.PP
