As in /r/ProgrammingLanguages, we will have a thread every month where you can post PL-related projects you are working on. Unlike the main posts, this thread is much more lenient: you should post even if you only have minor updates or something tangentially related to programming languages.

How much progress have you made since last time? What new ideas have you stumbled upon, what old ideas have you abandoned? What new projects have you started? What are you working on?

Once again, feel free to share anything you’ve been working on, old or new, simple or complex, tiny or huge, whether you want to share and discuss it, or simply brag about it - or just about anything you feel like sharing!

The monthly thread is the place for you to engage /c/programming_languages on things that you might not have wanted to put up a post for - progress, ideas, maybe even a slick new chair you built in your garage. Share your projects and thoughts on others’ ideas, and most importantly, have a great and productive month!

    Here’s a couple example programs.

    hello_world.mjut

    # Print a simple hello world message
let msg :: &Char = "Hello, world!\n"
mutate:
- stdout write msg

    truth_machine.mjut

    # Truth machine - if you input a 1, it prints 1 forever
# But a 0, it prints 0 & quits
let inp :: Char = 0
mutate:
- stdin alloc_read_line # Read data into stdin :: &Char
- inp := stdin:0
- inp -= '0'
- if inp - goto quit;
- forever:
    + stdout write "1"
    + goto forever
- quit:
    + stdout write "0"

    I think I have it fleshed out enough to get a basic version working. I’ll write up a lexer and parser tomorrow (it’s after midnight, so actually today lol) probably
