[antlr-interest] 2.7.2, unicode, and VC++

[Albert Huh]

Ooops,

Sorry everybody.  I guess I didn't dig deep enough into the archives.  Found the relevant posts =)

Anyways, I suppose a BETTER question is:

Is there a patch available for 2.7.2 to support VC++ 6.0 and unicode?  If so, does anybody have experience using this patch in a production environment?

Thanks,
Albert

Hi,

I'm trying to get the unicode example supplied with antlr 2.7.2 to work in visual c++ 6.0.

If I compile the grammar, then try to compile the generated code, I get the following errors:

C:\antlr-2.7.2\examples\cpp\unicode\unicode\L.cpp(172) : warning C4129: 'u' : unrecognized character escape sequence
C:\antlr-2.7.2\examples\cpp\unicode\unicode\L.cpp(172) : error C2015: too many characters in constant
C:\antlr-2.7.2\examples\cpp\unicode\unicode\L.cpp(173) : warning C4129: 'u' : unrecognized character escape sequence
C:\antlr-2.7.2\examples\cpp\unicode\unicode\L.cpp(173) : error C2015: too many characters in constant

FYI, the generated code is:

	if (((LA(1) >= static_cast<unsigned short>('\200') && LA(1) <= static_cast<unsigned char>('\ufffe')))) {
		matchRange(static_cast<unsigned char>('\200'),static_cast<unsigned char>('\ufffe'));
	}

Has anybody managed to get the unicode example to work in VC++ 6.0?

Anyhow, I've read in the archives that unicode is accepted, although not fully supported (i.e. feeding in UTF-8 text should be okay).  At the same time, antlr in C++ mode doesn't support unicode of the of box?  Sorry, I'm confused by these two ideas. 

Thanks,
Albert
