ANTLR worked great when other codes were written in Java, but it was a
little bit painful when using other languages like python.<br>
<br>
I worked on it two years ago. I guess they might have some improvement
now.<br><font color="#888888">

Does anyone have any experience with ANTLR for parsing C++ and for
extending their C++ parser? Any other feedback on ANTLR in general
would be welcome too. Thanks,<br>
