run mbasic in a browser (no webserver needed)

[aaw...@gmail.com]

A new project https://github.com/avwohl/mbasicc_web  runs the mbasic language in a web browser.  Try it at https://www.awohl.com/mbasicc. No, not in JavaScript, nor emulating an 8080. This is a new, portable implementation of MBASIC 5.21 in C++ for embedded systems, see https://github.com/avwohl/mbasicc, great for running basic in a toaster or wristwatch.

The C++ code is compiled by em++ to WebAssembly for running in a modern web browser.

I've always wanted Ada for CP/M. There's a version of RR Ada floating around but no doc. It is a shame that Gnu Ada doesn't cross compile to Z80 and CP/M.

Why not? I haven't messed with Ada since it was first selected as the language for the DOD competition.  If I have tokens left out of my weekly CLAUDE allotment, I'll have it work on Ada for Z80.  Current state:

We recently made a PLM language compiler to z80
see ~/src/uplm80.  Do the same for the full ada
language. As minimum for testing pass ACATS.
There is a lot of good peekhole and post optimizaiton
in uplm80.  See if that can be factored out and shared
with this project.

COMPLETED:
- [x] download ada spectifications
- [x] download the ACATS test suite
- [x] do your planning for a big job thing
- [x] analyze uplm80 optimization code
- [x] design compiler architecture
- [x] plan language subset
- [x] create project structure

NEXT STEPS (Phase 1 - MVP):
- [ ] implement lexer
- [ ] implement parser (basic subset)
- [ ] define AST nodes
- [ ] implement semantic analysis
- [ ] implement simple code generator
- [ ] compile "Hello World" program

I've been working on a Z80 compiler and learning Ada on the Z80 class.  See:

https://github.com/avwohl/learn-ada-z80

https://github.com/avwohl/uada80

I could use your feedback as you might be the only person to ever use it.

Hi Aaron,

that's cool... I wanted since the 80's to learn and use Ada,,,

thanks,
