Debugging with ANTLRWorks

The ANTLRWorks tool is written in Java and is only able to debug Java recognizers directly. Nevertheless, you can debug your C# recognizers with ANTLRWorks by using the Remote Debugging feature of ANTLRWorks. In ANTLRWorks, Remote Debugging works by connectiong to a running instance of a debug-instrumented recognizer (generated with the -debug switch to ANTLR) over the network.

To debug your C# recognizer with ANTLRWorks:

1. Generate a debuggable version of your recognizer by specifying the -debug option to ANTLR
2. Create a driver program that creates your recognizer and runs some test input through it
3. Compile your driver and recognizer to produce your executable file(s)
4. Execute your driver program (it will launch your recognizer and appear to hang - it's just waiting for ANTLRWorks to connect)
5. Start ANTLRWorks (or switch to it if it is already running) and click the menu Debugger|Debug Remote...
6. Click Connect to accept the default host and port values (localhost and 49153 respectively)
7. ANTLRWorks should now start debugging your recognizer!
