Great project! To keep WSL offline, just block the WSL instance in Windows Firewall or disable its virtual network adapter. Good luck with Interlisp Medley!

I just remembered that I have Kali Linux for WSL, I'll still try to add interlisp medley onto it. (I do want to make Kali Linux WSL become offline, but that might be tricky since I have the MS version) #WSL-stuff #tech-stuff #blog

Although less known than the LOOPS class browser, Medley Interlisp also comes with a browser for the CLOS Common Lisp Object System. The documentation of the CLOS browser gives an idea of what it can do.

The earliest spreadsheet programs were written in Assembly, C, and... Interlisp!
In 1982 Daniel M. Russell "created InterCalc (constraint-based reasoning in a spreadsheet) with J.S. Brown and Johan DeKleer" in Interlisp.

I still want to at least try to boot up Medley interlisp for WSL, for Debian, and be able to use it offline, I hope I can get away with doing this on a Win11 laptop.

On Medley Interlisp press Ctrl-B (B as in break) to interrupt a computation and bring up the debugger (break window). Here we did it while running an infinite loop that prints the loop index.

Screenshot of the black and white desktop of a 1980s graphical workstation environment. The desktop has a gray background pattern and some windows with a white background and a title bar with white text on a black background. One of the main windows, in reverse video, shows the output of a Lisp code loop that prints the loop index. Another window is a debugger subdivided into three panes: a list of stack frames, the currently selected frame, and an interactive command pane.

Interlisp source files contain a file map, a data structure with the locations of functions & definitions within the file. This metadata is a hint to the system for directly loading or accessing the definitions, with scanning the file as a fallback.
