origin-studio

origin-stdio is an alternative [std]-like implementation built on [origin].

At this time, it only works on Linux, requires Rust nightly, lacks full std compatibility, and is overall experimental. But it supports threads and stuff.

Quick start:

In an empty directory, on Linux, with Rust nightly, run these commands: sh cargo init cargo add origin_studio cargo add compiler_builtins --features=mem echo 'fn main() { println!("cargo:rustc-link-arg=-nostartfiles"); }' > build.rs sed -i '1s/^/#![no_std]\n#![no_main]\norigin_studio::no_problem!();\n\n/' src/main.rs cargo +nightly run --quiet

This will produce a crate and print "Hello, world!".

Yes, you might say, I could have already done that, with just the first and last commands. But this version uses origin to start and stop the program, and [rustix] to do the printing. And beyond that, it uses [origin] to start and stop threads, [rustix-futex-sync] to do locking for threads, and [rustix-dlmalloc] to do memory allocation, so it doesn't use libc at all.
