The high level idea reminds me of Pharo:

The idea to put the program and runtime together in one unit was core to Smalltalk of course but with Pharo you can get also the "IDE part" bundled.

Once in a time there were even whole computers build on this concept: LISP-machines! Everything running on a LISP-machine is reachable and modifiable by the user (at runtime!) and you would have a build in IDE-like editing facility.

> There is little protection against changing the operating system. The whole system is fully accessible and changeable.

DevTools in Browsers are today the closest thing to something like that I guess. But you can only edit a webpage. It's not going down to the level of the OS of course.

Thanks for submitting my 4-week old project! Here's a 3-minute demo video showing what it's like to use it right now: https://archive.org/details/akkartik-2021-11-14

There's a similar project called PICO-8.

https://www.lexaloffle.com/pico-8.php

It's a virtual console, with each game released so that the source is available and editable by design. The IDE has an integrated code editor, sprite editor, and music editor. The console side has cloud access to download new games and demos.

This reminds me of QBasic for DOS -- you have the code and the execution environment tightly integrated. (I think QBasic did have some graphics support, though?)

Thinking back on it, QBasic might have created a generation of programmers -- you would copy a working game from a friend, and then try to modify the source code to let yourself cheat.

Heh, I have another project that's recreating Basic and DOS on some level. Statement-oriented language, SVGA graphics. No networking, no virtual memory, no concurrency. Unlike its forebears, though, lots of RAM and disk, which changes many design choices. And memory-safe code as far as possible; no C anywhere in its dependencies. https://github.com/akkartik/mu

Teliva is basically providing better networking and disk support by compromising on the memory safety. (I'm back to depending hugely on C.)

The 64K EGA card in my machine only went up to SCREEN 8 (640×200, 16 colors). SCREEN 13 was a distant dream!

QB64 has a compatible statement that supports the original modes: https://www.qb64.org/wiki/SCREEN_(statement)#Legacy_Screen_M...

Yep, my first one. If you don't count .BAT programming.

I remember when I was a kid, my father did this to a qbasic game with two monkeys throwing bananas. He eventually modified it so they can throw two instead of one.

Oh yes, good old GORILLA.BAS

From antirez there is load81[0] which does kind of the same and it's lovely for playing around with installing 1 thing, playing a game, breaking into the source and changing code on the fly.

If you're interested in this kind of thing, also check out the Glamorous Toolkit. It basically is a coding environment where you edit itself as it runs.

+100 for Glamorous Toolkit. I actually played with it before starting Teliva, and hope to continue using it.

This looks awesome! It's to a large part like a modern shell environment I try to imagine since some time. Maybe it needs more data-flow spread-sheet features, need to check it out, but the screenshots strongly point into the right direction.

Funny coincidence that it's build in Pharo which I've mentioned here in another comment. :-)

This is a nice palette cleanser after the "disable view source" from the Chrome monopoly.
