1 Release 1.0.2 of wrc (20-Jun-1998), the wine resource compiler.
3 See the file CHANGES for differences between the version and what has been
4 corrected in the current version.
9 - 16 and 32 bit support
10 - LANGUAGE support (32 bit only)
11 - almost all resource types are supported
12 - enhanced expression capabilities and resource naming
13 - indirect loadable resources
14 - NE/PE resource directory generation
15 - binary .res file generation/reading
17 Wrc generates an assembly file that can be assembled with GNU's gas, or
18 passed to gcc. The assembly became necessary for two reasons. First, C does
19 not ensure relative position of declared data. Secondly, C complaints about
20 complex initialization schemes that became necessary with the NE/PE
26 You can get this message by typing 'wrc -?':
28 Usage: wrc [options...] [infile[.rc|.res]]
29 -a n Alignment of resource (win16 only, default is 4)
30 -A Auto register resources (only with gcc 2.7 and better)
31 -b Create a C array from a binary .res file
32 -c Add 'const' prefix to C constants
33 -C cp Set the resource's codepage to cp (default is 0)
34 -d n Set debug level to 'n'
35 -D id[=val] Define preprocessor identifier id=val
36 -e Disable recognition of win32 keywords in 16bit compile
37 -g Add symbols to the global c namespace
38 -h Also generate a .h file
39 -H file Same as -h but written to file
40 -I path Set include search dir to path (multiple -I allowed)
41 -l lan Set default language to lan (default is neutral {0})
42 -L Leave case of embedded filenames as is
43 -n Do not generate .s file
44 -o file Output to file (default is infile.[res|s|h]
45 -p prefix Give a prefix for the generated names
46 -r Create binary .res file (compile only)
47 -s Add structure with win32/16 (PE/NE) resource directory
48 -t Generate indirect loadable resource tables
49 -T Generate only indirect loadable resources tables
50 -V Print version end exit
51 -w 16|32 Select win16 or win32 output (default is win32)
52 -W Enable pedantic warnings
54 Input is taken from stdin if no sourcefile specified.
56 Debug level 'n' is a bitmask with following meaning:
57 * 0x01 Tell which resource is parsed (verbose mode)
58 * 0x02 Dump internal structures
59 * 0x04 Create a parser trace (yydebug=1)
61 The -o option only applies to the final destination file, which is
62 in case of normal compile a .s file. You must use the '-H header.h'
63 option to override the header-filename.
64 If no input filename is given and the output name is not overridden
65 with -o and/or -H, then the output is written to "wrc.tab.[sh]"
70 The build-in preprocessor is not a full implementation of the C counterpart.
71 Wrc does not understand function-type macros. These are discarded as they
72 are scanned. This will be a future project. Wrc does understand these:
82 Also 'defined' is supported as operator (both with and without parenthesis).
83 '#if' expressions can be anything valid that evaluates to an integer
84 expression (where 0 is false and anything else is true). Others (#pragma,
85 #line) are ignored. A special case '#' generates an error. This is due to
86 the implementation to enable generation of errors on preprocessing and will
87 be improved in the future.
92 All of wrc is layed out in such a way that it enables compilation of both 16
93 and 32 bit resources. They mainly differ in code-generation and extra
94 keywords. Win32 keywords are recognized by default in 16 bit compile. You
95 can disable recognition of win32 reserved keywords by using the '-e' option,
96 if you encounter .rc-files that use win32 reserved keywords (I strongly
97 recommend that you just rename things in the source).
102 Wrc also understands the LANGUAGE keyword (win32 only) for both global and
103 local definitions of language. There are differences with respect to MS' and
104 Borland's implementation. Wrc uses 0,0 as the default language if non is
105 specified. Both MS and Borland use the language of the system that the
108 Not all resource-types can have local language keywords attached yet
109 (notably: BITMAP, CURSOR, ICON and usertype). This is due to implementation
110 of filename-scanning and the complexity that it poses. This will be changed
111 in the next release. You can work arround this problem by putting a LANGUAGE
112 statement before (and evt. after) the code in the resource file.
115 Resource types supported
116 ------------------------
117 All types are supported except for:
120 - extensions like TOOLBAR and the like (is this a user-type?)
122 These types will be implemented as soon as I get a proper specification of
125 Note: Usertype resources with character strings as types have a different
126 layout and do not accept expressions when a numerical type is specified. The
127 must be enclosed in double quotes. These are examples of valid usertype
130 MyName "MyType" mydata.bin
131 MyName 12345 mydata.bin
132 MyName "MyType" "mydata.bin"
133 MyName 12345 "mydata.bin"
148 Expression capabilities and resource names
149 ------------------------------------------
150 You can use an expression in most places where the resource definition
151 expects a number (except usertype type). Operators supported:
159 ~ binary not (unary operator though)
162 Minus (-) can both be unary and binary. The NOT operator is (primarily)
163 used to disable window styles but I strongly suggest to refrain from using
165 There is a shift/reduce conflict on the unary minus, but this is not
166 problematic. I was too lazy to make a new expression parser (next version or
167 so). Unary plus (+) would cause another confilct, so I let it out for now.
169 Resource names can be both numerical (expressions) and character typed. Wrc
170 does supports this insane (deep sigh) construct:
177 It is _ONLY_ supported for backwards compatibility so that old sources can
178 be compiled with winelib. DO NOT USE IT IN NEW RESOURCES, PLEASE!
181 Indirect loadable resources
182 ---------------------------
184 Wrc can generate tables for indirect resource loading like winerc did. There
185 are two new structures defined in 'wine-base-dir/include/wrc_rsc.h':
187 typedef struct wrc_resource16
189 INT32 resid; /* The resource id if resname == NULL */
191 INT32 restype; /* The resource type-id if typename == NULL */
193 LPBYTE data; /* Actual resource data */
194 UINT32 datasize; /* The size of the resource */
197 typedef struct wrc_resource32
199 INT32 resid; /* The resource id if resname == NULL */
201 INT32 restype; /* The resource type-id if typename == NULL */
203 LPBYTE data; /* Actual resource data */
204 UINT32 datasize; /* The size of the resource */
207 The extension to winerc lies in the addition of the 'typename' field to
208 support usertype resoursec with names for types.
210 Note that _ALL_ names generated by wrc and to be used in interfacing with
211 wine are PASCAL-style strings, unlike winerc. The first element contains the
212 length and the strings are _not_ '\0'-terminated!
214 You can also generate header files with wrc when specifying the '-h' or
215 '-H<filename>' option.
218 NE/PE resource directory generation
219 -----------------------------------
220 A windows executable has a table/directory of resources avalable in that
221 module. Wrc will generate this directory with the '-s' option and place it
222 in the assembly output (and header-file). This will enable the separation
223 of different modules (dlls) in wine, which is the next project after wrc.
225 The layout of the PE directory should be exactly like the executable file.
226 The NE-directory layout _DIFFERS_ from the real NE-executable in such way
227 that all offsets to actual resource-data is relative to the NE-directory and
228 _NOT_ the beginning of the file.
231 Binary .res file generation/reading
232 -----------------------------------
233 Wrc can both generate (32 and 16 bit) and read (32 bit only) .res-files.
234 These can be used as intermediate files or binary files can be imported from
235 other sources. The reading of 16 bit .res-files is on the list for the next
238 You cannot convert 32 bit .res-files into 16 bit output or vice versa. I
239 might implement 16 bit res into 32 bit output in the future, but I stronly
240 oppose to the other way arround.
245 Inherent to programs you have bugs. These I know are there, plus a few
246 things that I noted in the above text (more lack of implementation than bug
248 - No codepage translation
249 - UNICODE translations are not/not correct implemented
250 - No documentation ('wrc -?' gives command-line options though)
251 - grep for FIXME in the source
252 - Memory options are wrong under some conditions. There seems to be a
253 different action for win32 and win16.
254 - User-type resources have slightly different layout.
255 - Filename scanning is still hopeless.
257 Reporting bugs and patches
258 --------------------------
259 Send problems to the wine newsgroup or, preferrably, directly to me at:
263 Please send the problematic rc-source with the bug so I can reproduce it.
264 Patches should _not_ be send to Alexandre but to me. I will then review the
265 change and send a full patch to be included into the new wine release (I
266 prefer 'diff -u' format). You can always upload suggestions to wine
267 headquarters, but be sure to send me a copy.
