Interpreters, Debuggers, and Development Tools

• Marc Majcher has written a Piet interpreter in Perl, documented here. This version has a buggy interpretation of crossing white blocks.
• Sylvain Tinitillier offers a bug-free perl version (zip file here).
• Erik Schoenfelder has written npiet, a very nice Piet interpreter with the ability to print program traces and a supporting Piet editor! It's feature-packed and the best version I'm aware of.
• Mark Schad has written HIPI, a graphical IDE and interpreter for Piet.
• Oscar Rodriguez has written PietDev, a graphical IDE and debugger for Piet, which runs in your browser using JavaScript!
• Ross Tucker has written a python version of Marc Majcher's interpreter, Piet.py (text file).
