Getting bison to ignore tokens... sometimes!

Hi, I am pretty sure bison cannot simply ignore tokens. However, I don't know what's the usual flex/bison pattern to solve this issue. I am implementing a parser for a language that terminates statements with a newline, however, the newline doesn't always terminate statements... only after a s

VCG visualization

Hello all, I am on a Mac and I would like to know if anybody has any suggestion on a free software to visualize vcg files resulting from bison output or convert them to a bitmap file. Cheers, -- Paulo Jorge Matos - pocm at soton.ac.uk http://www.personal.soton.ac.uk/pocm PhD Student @ ECS Unive

Location Tracking

Hi all, When generating C++, If I don't use %locations, why do I still get a locations and position files? Are they required anyway? Moreover, error in parser class still gets a reference to a location. If I don't use locations, what reference is that? I would expect when disabling locations that

Undefined Ids

[I'm sorry for cross-posting but I think this might concern both lists] Hello, I've generated a C++ Parser and C++ Scanner with bison 2.3 and flex 2.5.33 respectively. They are both prefixed with smt in my case. I've been also having a hard time to use both together without trouble and unfortuna

Generated parser searching for y.tab.c

Using C++ generated parsers with autotools

Hello all, If you're currently using autotools with C++ generated parsers, how do you handle all those generated files within autotools? How do you say location.hh and position.hh and others were generated by bison and they should be cleaned up? Regards, -- Paulo Jorge Matos - pocm at soton.ac.u

Memory Leaks

Hi all, I've generated a parser with bison and I tried running valgrind on it. The wierd thing is... there's a huge bunch of memory leaks reported. :-( Is this known? Is this a bison leak or a valgrind bug? Regards, -- Paulo Jorge Matos - pocm at soton.ac.uk http://www.personal.soton.ac.uk/poc

Disabling Actions

Hi all, I've developed a parter with flex/bison and I would like to find a simple way to check how long it takes to parse the file without executing the actions. Is there an option I can enable to ignore actions? Regards, -- Paulo Jorge Matos - pocm at soton.ac.uk http://www.personal.soton.ac.uk

Citing the Bison Manual
