Issues with combined grammars

[ohboyohboyohboy]

Hey there,

Thanks for the bug report. Sorry I haven't replied yet -- I'm a bit strapped for time this week. Recently, I ironed out most of the compatibility with ruby 1.9 by restructuring the StringStream class a bit. I'm pretty sure that the error indicates that I haven't made corresponding changes in the InteractiveStream class that the lexer interpreter shell uses. Unfortunately, this feature isn't covered particularly well in the functional testing.

I should have free time on Thursday evening or Friday to take a look through the code and fix any bugs.

With regard to the lexer warnings, do you get those when you run with ruby 1.8.7 (if you have it) too? I had that problem in the past, but I corrected it. I'll have to try it out some of my grammar delegation tests directly with 1.9.1 and trace out how the files are being loaded. There may be a change in the semantics of autoload I wasn't aware of or something else of that nature.

If you have any additional info, or if you want to share your grammars, feel free to let me know. I'll get back to you shortly.

Thanks,
Kyle

That's a small hobby project and isn't anything critical, so delays are absolutely fine. I first tried to fix that by myself, but as I'm new to parsers and ANTLR internals a bit scary, so I haven't succeeded...

Also, I just determined that the bug isn't triggered by delegation, it is much less specific: this (very basic) grammar causes it as well: http://gist.github.com/636268
