Hi Gary,


The fuzzy parsers for C++ I know about are the etags program in Emacs
Version 19 (originally derived from Ken Arnold's ctags; C++ support
added by me), and Sniff, a fuzzy-parser-based environment. See Walter
Bischofberger, "Sniff: A Pragmatic Approach to a C++ Programming
Environment", USENIX C++, 1992. For the purposes of fuzzy parsing, C is
a strict subset of C++.


Etags tries only to detect definitions of various entities, and does a
pretty good job. (It has plenty of deficiencies, though, and I don't
plan to fix them since I'm working in the wonderful Modula-3 language.
Any volunteers to add features to etags? If so contact me.) Sniff
claims to find much more, though I've never used it. C++ seems designed
to make parsing as difficult as possible.
