I had to rewarm my Java and Swing skills and thus wrote an integrated development environment for the Hacker Virtual Machine. Now that it is quite stable and I have learned all I need, why not sharing it? So here it is for all the world to use:
To use it, unpack the archive anywhere you want and double-click HackerVirtualMachine.jar. Doesn't work? Then you probably need a Java Runtime Environment...
If you think you found a bug, please mail a .hvm file along with a description how to reproduce it to colonel.dump at gmail dot com.
