Annex

Annex is a hobbyist imperative, compiled programming language. It compiles to RISC-V assembly and is built in Rust. It aims to implement the standard compiler workflow from scratch with minimal dependencies, including lexical analysis, parsing, abstract syntax tree generation, semantic analysis, and code generation.

Its syntax is roughly inspired by LLVM and Rust. A sample snippet:

var i32[10] arr = 0;
var i32 x = 0;
const u32 addr = 1000009;
var i32[2] y = arr[3];

fn process_array{var i32[100] input} i32 {
    return input[50];
}

with the full language grammar specified at annex.g4.
