Re: [cdt-dev] LR parser

It hasn't been dropped as far as I know... and is needed by the UPC editor. I think other folks have used this more generalized parser for other things too.

UPC is an important language for Parallel Application developers and their eyes always light up when I say that Eclipse supports it.

Yes, I think the LR (general) parser could use some TLC. I think its underlying use of LPG (http://sourceforge.net/projects/lpg/) could stand to be updated, but I think it works as it is so far with an older version

LR parser (part of CDT) needs a champion and a little TLC...

If the LR parser is deprecated, how do we extend the pre-processor (#defines, etc.) part of the GNUCPPSourceParser? I've attempted to do this before, but I had to duplicate so much of the existing CDT code inside of my language plugin, it felt like I was duplicating the entire CDT.

Is adding new pre-processor keywords to the new existing parser supported?

Sorry to hijack a thread, I just wanted to present a use-case that may not be supported with the existing parser.

Why was the LR parser dropped? No maintainer? Too slow?

Thanks.

The short answer is no, it wasn't really an alternative. And it's pretty near dead as far as I can tell.

Is the LR parser (org.eclipse.cdt.core.lrparser) supposed to be an
alternative for GNUCPPSourceParser?

Does anyone use it?

Does anyone maintain it? I have made some fixes to GNUCPPSourceParser
in the past but have not made corresponding fixes to the LR parser.

Thanks,
Nate
