At this point I have a very simple syntax for programming pretty much directly in machine code: https://github.com/akkartik/mu#readme. It can be translated to an ELF binary for Linux using about 250KB of static x86 instructions (80% of which are unit tests, and much else of which is duplicated because I built the translator in multiple passes that run in a shell pipeline:
The nice thing about the resulting ELF binaries is that they can be run directly on a Linux kernel with no other dependencies. Not even libc.
There's a script in the repo called `gen_iso` that can take a list of .subx files, translate them into an ELF binary and package up the ELF binary with just a Linux kernel into a bootable disk image. You can then boot this image either in Qemu or on a cloud service like Linode (http://akkartik.name/post/iso-on-linode)
This is what I have so far.
By contrast, the screenshot is quite fake. It's just a program that reads a line of text from the keyboard and prints it out to the screen. You can see it running on an emulated computer in Qemu that has nothing but a Linux kernel.
But I'm going to build up from that core into a high-level language. Maybe an Arc-inspired Lisp. Not a toy this time around.
Just give me 5 more years :D
To reiterate the main project link: https://github.com/akkartik/mu#readme. Should hopefully be pretty easy to get running on Mac or Linux. (Though you're mostly on Windows, right jsgrahamus? I'm really sorry I still don't know Windows well enough to support it :( )
