The Sage Programming Language
Sage is a Rust-like programming language built on a brainfuck-inspired VM with LLVM-like properties. https://github.com/adam-mcdaniel/sage Check out the web-demo to run the compiler in the browser, along with a graphical example using JavaScript interop! https://adam-mcdaniel.net/sage Sage is designed to be portable, but also useful. To prove its usefulness, I used it to implement a user-space for a new operating system: SageOS https://github.com/adam-mcdaniel/sage-os The language also runs on embedded devices, like the flipper zero!
In plain words
Sage is a Rust-like programming language built on a brainfuck-inspired virtual machine with LLVM-like compilation properties. Designed for portability across platforms, it runs in web browsers, powers the user-space of SageOS, and executes on embedded devices including the Flipper Zero. Developers can test the compiler directly in a web demo that includes JavaScript interoperability features.
