Obsidian Language v0.0.2

Obsidian is a compiled programming language that combines memory safety, zero-cost abstractions, and minimalist syntax. Built for developers who want the speed of Rust without the boilerplate.

This is a toy implementation (v0.0.1) written in Python. It features a lexer, parser, AST, and a transpiler to Python (which simulates "compilation" by generating and executing equivalent Python code). Published on PyPI as obsidian-lang.

Features (v0.0.2)

• Minimalist syntax inspired by Rust
• Variables with let (optional type hints, e.g. let x: int = 5;)
• Functions with fn
• Basic expressions + comparison operators (< > <= >= == !=)
• Control flow with if / else
• Control flow with while
• Function calls (including built-in println)
• Optional semicolons (statements can omit ; at end of line)

v0.0.2 update: Added support for while loops (building directly on v0.0.2a state with optional type hints on let, optional semicolons via _maybe_semi(), and all prior features).

Installation

pip install obsidian-lang

Usage

# After pip install obsidian-lang
obsidian examples/hello.obs --show-code

# Or from source (development)
PYTHONPATH=. python -m obsidian.main examples/hello.obs --show-code

Example (hello.obs)

fn main() {
    let x = 5;
    let y = x + 3;
    println(y);
    println("Hello from Obsidian!");
}

Example (while.obs)

fn main() {
    let i: int = 0
    while i < 3 {
        println(i)
        let i = i + 1
    }
    println("while loop done")
}
