apjanke / antlrworks2-jank

apjanke's fork of ANTLRWorks to support ANTLR 4.8 and macOS 11.13+

ANTLRWorks2-Jank

ANTLRWorks2-Jank is apjanke's fork of ANTLRWorks. Development has stalled upstream since Terrence Parr and the other developers are focusing on IntelliJ and other IDE plugins now. So I thought I'd pick up the code and see if I can get it running, since I'm curious about ANTLRWorks. This is not an official ANTLR project!

Background

The last upstream release of ANTLRWorks on GitHub was version 2.5.3 in September 2016, and targeted NetBeans 8.1. The head of master in upstream is targeting NetBeans 8.2 and ANTLR 4.6. As of January 2020, NetBeans has transitioned to Apache and is now up to version 11, and ANTLR is up to 4.8.

Status

I'm currently still working on just getting the project to build under NetBeans 11 and my development setup.

Author and Support

ANTLRWorks2-Jank is maintained by Andrew Janke. The project home page is https://github.com/apjanke/antlrworks2-jank.

Don't contact the ANTLR folks about this project! They won't know what you're talking about.

NPE when compiling in my WIP-ditch-ATN stuff

Sheesh. When compiling the latest work-in-progress version of my code (on branch mavenize/ditch-ATN-simulator), I'm getting a NullPointerException apparently raised inside the javac code when it's called by the Maven Compiler Plugin.
