Sebastien, Thanks for the feedback. Is it in this line?: if (c == NULL) { IoLexer_popPosBack(self); return 0; } If so, does this fix it?: if (c == 0x0) {...
Hi Steve! On Wed, 2 Apr 2003 02:09:59 -0800 ... Yes! this fixes the warning (you've got to do it at both line 405 and 423). -- Sebastien...

Hi all, I was wondering if some `char *' in Io should not be `const char *' instead, like in the print callback (IoState_printCallback_). I don't think the...

Hi again! It seems like there is a typo in the `Embedding' section of IoVM manual: <snip> #include "IoState.h" void MyPrint(void *state, char *s) { printf(s);...

... Yes, you're right. I need to clean that up at some point. Thanks for the reminder. Cheers, Steve Io, a small language: http://www.iolanguage.com/...
Sebastien, ... Thanks for the fix! ... Oops, I got a bit aggressive with search&replace. That should really be "IoState_printCallback_" in IoState. I'll fix...

I don't really know what to call things in Io. The normal nomenclature that I use for conventional class-based OO languages just doesn't apply to Io....

... Currently, inheritance lookups use getSlot(), so they don't activate blocks. So when c follows it's parent slot to lookup foo it finds a block and ignores...
