wmc - Wine Message Compiler


wmc [options] [inputfile]


wmc compiles messages from inputfile into FormatMessage[AW] compatible format encapsulated in a resourcescript format. wmc outputs the data either in a standard .bin formatted binary file, or can generated inline resource data.
wmc takes only one inputfile as argument (see BUGS). The inputfile normally has extension .mc. The messages are read from standard input if no inputfile is given. If the outputfile is not specified with -o, then wmc will write the output to inputfile.{rc,h}. The outputfile is named{rc,h} if no inputfile was given.


-B x
Set output byte-order x={n[ative], l[ittle], b[ig]}. Default is n[ative].
Set 'custom-bit' in message-code values.
NON-FUNCTIONAL; Use decimal values in output
Set debug flag. This results is a parser trace and a lot of extra messages.
Print an informative usage message.
-H file
Write headerfile to file. Default is inputfile.h.
Inline messagetable(s). This option skips the generation of all .bin files and writes all output into the .rc file. This encoding is parsable with wrc(1).
-o file
Output to file. Default is inputfile.rc.
-O format
Set the output format. Supported formats are rc (the default), res, and pot.
-P directory
Enable the generation of resource translations based on po files loaded from the specified directory. That directory must follow the gettext convention, in particular in must contain one .po file for each language, and a LINGUAS file listing the available languages.
Assume that the inputfile is in unicode.
Write resource output in unicode formatted messagetable(s).
Show all supported codepages and languages.
Print version end exit.
Enable pedantic warnings.


The original syntax is extended to support codepages more smoothly. Normally, codepages are based on the DOS-codepage from the language setting. The original syntax only allows the destination codepage to be set. However, this is not enough for non-DOS systems which do not use unicode source-files.
A new keyword Codepages is introduced to set both input and output codepages to anything one wants for each language. The syntax is similar to the other constructs:
Codepages '=' '(' language '=' cpin ':' cpout ... ')'
The language is the numerical language-ID or the alias set with LanguageNames. The input-codepage cpin and output-codepage cpout are the numerical codepage-IDs. There can be multiple mapping within the definition and the definition may occur more than once.


wmc was written by Bertho A. Stultiens.


The message compiler should be able to have multiple inputfiles and combine them into one outputfile. This would enable the splitting of languages into separate files.
Unicode detection of the input is suboptimal, to say the least. It should recognize byte-order-marks (BOM) and decide what to do.
Decimal output is completely lacking. Don't know whether it should be implemented because it is a, well, non-informative format change. It is recognized on the commandline for some form of compatibility.
