annonçant zkeme80 - un système d'exploitation pour le ti-84+

Bonjour tout le monde!

https://github.com/siraben/zkeme80

J'aimerais partager un projet sur lequel je travaille depuis un mois. Ça s'appelle zkeme80, un nouveau système d'exploitation pour le ti-84+. La caractéristique importante est que la majeure partie est écrite dans le langage de programmation Forth. Ce n'est pas fini, mais le noyau est. J'ai aussi écrit l'assembleur parce que les systèmes macro existants dans d'autres assembleurs ne sont pas suffisants. L'assembleur est écrit dans le langage de programmation Scheme. Il est facile de compiler le système d'exploitation, il suffit d'exécuter « make build » dans le répertoire.

Je m'excuse pour mon français, ça fait longtemps que je n’utilise pas le français

The TI-84 does not exist.

Apologies, meant the TI-84+. Updated!

It's interesting to see this kind of projects pop up, especially with such a choice of unusual - but of course valid - implementation languages

I couldn't find the information on the Readme so I guess the answer is "no", but can it run ASM programs compiled for the TI-OS (I obviously don't expect it to run TI-Basic programs)?

Anyway, I'm really wondering about the Forth part. I kinda agree with the "Why Forth?" section of the readme (though I don't know if there are any alternatives, at least I agree that assembly makes it very annoying to create something as big as an OS). But on the other hand, who knows Forth (I mean that question as a potential limitation for contributors)? But on the other other hand, still, who wants to use assembly?

No, currently there is no link support.

You might be interested in my previous project, a Forth interpreter/compiler that works under TIOS. https://github.com/siraben/ti84-forth

Forth has a niche community, but it has been used in the real world, for instance the Philae spacecraft lander.

https://www.forth.com/starting-forth/ is a good tutorial for beginning Forth programmers
https://github.com/nornagon/jonesforth/ ... nesforth.S has great comments about implementing it for the x86 under Linux

Yes yes, I meant it more as a limitation for contributors in the context of the project (I edited my message).
Forth has a niche community, calculators have a niche community too, I'm kind of wondering about the intersection.
But on the other hand people who would want to contribute to the project probably wouldn't want pure assembly.
So I'm really curious about what's going to happen

The idea is that people share a common kernel, and the .fs files can be interchanged between each other. I also made sure it was extremely easy to build, so the only dependency is a recent enough version of Guile. I hope someone manages to create a REPL for it eventually. Documentation, of course, is the next step!
