Zero Compiler

A high-performance compiler for the Zero programming language, designed for AI/ML workloads.

Quick Start

# Build the compiler
cmake -B build
cmake --build build --config Debug

# Run a Zero program
.\build\bin\Debug\zeroc.exe examples\calculator.zero

# Dump IR for debugging
.\build\bin\Debug\zeroc.exe --dump-ir examples\hello.zero

Language Features

Variables and Types

let x = 42          // Integer
let y = 3.14        // Float
let msg = "Hello"   // String

Arithmetic

let sum = a + b     // Addition
let diff = a - b    // Subtraction
let prod = a * b    // Multiplication
let quot = a / b    // Division
let expr = (a + b) * 2  // Grouped expressions

Control Flow

if x > 10 {
    print("Large")
} else {
    print("Small")
}

while count > 0 {
    count = count - 1
}

Functions

fn add(a: int, b: int) -> int {
    return a + b
}

fn main() {
    print(add(10, 20))
    return 0
}

Built-in Functions

Function	Description	Example
print(...)	Print values	print("Hello", 42)
log(msg, color="...")	Colored output	log("OK", color="green")

Colors: red, green, yellow, blue, magenta, cyan
