Guido van Rossum, as well as being the creator of the Python language, is the original creator of IDLE. Other contributors prior to Version 0.8 include Mark Hammond, Jeremy Hylton, Tim Peters, and Moshe Zadka. IDLE's recent development was carried out in the SF IDLEfork project. The objective was to develop a version of IDLE which had an execution environment which could be initialized prior to each run of user code. The IDLEfork project was initiated by David Scherer, with some help from Peter Schneider-Kamp and Nicholas Riley. David wrote the first version of the RPC code and designed a fast turn-around environment for VPython. Guido developed the RPC code and Remote Debugger currently integrated in IDLE. Bruce Sherwood contributed considerable time testing and suggesting improvements. Besides David and Guido, the main developers who were active on IDLEfork are Stephen M. Gava, who implemented the configuration GUI, the new configuration system, and the About dialog, and Kurt B. Kaiser, who completed the integration of the RPC and remote debugger, implemented the threaded subprocess, and made a number of usability enhancements. Other contributors include Raymond Hettinger, Tony Lownds (Mac integration), Neal Norwitz (code check and clean-up), Ronald Oussoren (Mac integration), Noam Raphael (Code Context, Call Tips, many other patches), and Chui Tey (RPC integration, debugger integration and persistent breakpoints). Scott David Daniels, Tal Einat, Hernan Foffani, Christos Georgiou, Jim Jewett, Martin v. Löwis, Jason Orendorff, Guilherme Polo, Josh Robb, Nigel Rowe, Bruce Sherwood, Jeff Shute, and Weeble have submitted useful patches. Thanks, guys!
