This page lets you run a couple of interactive demonstration of zyacc's debugger using a java applet based GUI. Absolutely no change needed to be made to either of the programs to generate the debugging applets. Each demonstration is run by starting a remote server process. To conserve resources, the server process will time out in about 15 minutes.
The first demonstration shows the parsing of the input
1 + 2 1 + 2*3using a simple arithmetic expression grammar.
The second demonstration shows the parsing of a simple C program using a complete Ansi-C parser running as part of the zprof source-to-source profiling tool. It shows the inadequacy of the GUI for handling the debugging of practical parsers on inputs of any reasonable size. It also may tax your patience, especially if you have a slow network connection.
