I am looking for a lex and yacc (or bison and flex) file definitions so that I
can parse C++ code. I would like to add some cook-book type code to all my C++
classes and something like this would be an ideal tool.

 This from the C++ FAQ at

  http://www.quadralay.com/www/CCForum/CC_FAQ.html

 It's more or less conformant with version 2.1 as far as I
know, ie. nested classes but no templates or exceptions 8-(. Still
it's a starting point. Bison and flex are now capable of generating
C++ output BTW.

A: Jim Roskind is the author of a yacc grammar for C++. It's roughly
compatible with the portion of the language implemented by
USL cfront 2.0. Jim's grammar deviates from cfront (and the ARM) in a
couple of what I understand to be minor ways. Ultimately
any deviation from a standard is unthinkable, but the number of real
programs thay is relatively small, so
the `consequence' of the deviation is not great.

I have used Jim's grammar when a grad student wrote a C++ templatizer
mechanism (reads ANSI-C++, spits out pre-templates
C++), but my expertise does not include precise knowledge ong sites:

   ics.uci.edu (128.195.1.1) in the ftp/gnu directory (even though
neither of the archives are GNU related) as:
      c++grammar2.0.tar.Z and byacc1.8.tar.Z
   mach1.npac.syr.edu (128.230.7.14) in the ftp/pub/C++ directory as:
      c++grammar2.0.tar.Z and byacc1.8.tar.z

Jim Roskind can be reached at jar@hq.ileaf.com or ...!uunet!leafusa!jar
