The 1999 "source code" referred to above is in two parts: xu88, the design my group worked out in 1979, now called "Xanadu Green", described in my book "Literary Machines"; and a later design I repudiate, called "Udanax Gold", which the team at XOC (not under direction of Roger Gregory or myself) redesigned for four years until terminated by Autodesk. That's the one with the dual implementation in Smalltalk. They tried hard but not on my watch. Please distinguish between these two endeavors.
Glad to hear from you, and I welcome your details and corrections to the record!
What are your opinions about scripting languages (not just for implementation, but for runtime extensibility)? Are they necessary from the start? Is JavaScript or TypeScript sufficient?
