This looks pretty cool. I've always wished for some kind of "2D REPL" experience with assembler, similar to what we can do in Common Lisp. The closest I've gotten to this was experimenting with SIMD intrinsics with SB-SIMD (an SBCL contrib library that provides tons of additional SIMD support to the compiler backend).
One niche use case I see for this minor mode is possibly learning how to program for microcontrollers with so little RAM that you can probably print each byte on a sheet of paper to debug (i.e. 4KiB of RAM or less)
This shows what people mean when they say Emacs is easy to extend. I don’t think most popular editors will let you code an extension like this in 167 lines including all boilerplate, comments, and documentation.
You can definitely accomplish something like this in VSCode and I would strongly encourage any student to explore customizing their own tools and workflow.
If you decide you want to do this and need help getting started feel free to email me.
I’m the last person who should carry rocks around in a glass house on HN etiquette: I mouth off too much.
But I’m working on it and I cordially invite you to join me in making an effort to be more productive, especially regarding students, self learners, and other more junior community members trying to get started on ambitious hacking.
I think GP is just asking if the author thinks it’s possible. I remember it was hard in the beginning to know - when I would get stuck - if I needed to keep banging my head against it or if I had hit a dead end.
You should exercise your own programming muscles and write your own IDE, Operating system , cpu architecture, fabrication process and electricity generation for yourself, rather than relying on others to do everything for you.
