Phoenix Language

🔥 A modern, statically-typed programming language with LLVM-powered compilation

Overview

Phoenix is a programming language designed for clarity, performance, and ease of use. It compiles directly to optimized machine code using LLVM, combining the speed of low-level languages with a clean, modern syntax.

Example Code

fun fibonacci(n: int) : int {
    if (n <= 1) {
        return n;
    }
    return fibonacci(n - 1) + fibonacci(n - 2);
}

fun main() {
    println("Hello from Phoenix!");

    // Vector operations
    var numbers: vec<int> = [1, 2, 3];
    push(numbers, 4);
    numbers[0] = 10;

    println("The 10th Fibonacci number is:");
    println(fibonacci(10));

    // Control flow
    for (var i = 0; i < 5; i++) {
        if (i > 2) {
            println("Bigger than 2");
        } else {
            println("Smaller than or equal to 2");
        }
    }
}

main();

Key Features

• Strong Static Typing: Catch errors at compile time
• First-class Functions: Functions as values
• Vector Support: Built-in arrays with dynamic operations
• Rich Control Flow: If/else, while loops, for loops
• Multiple Data Types: Integer, float, boolean, string
• LLVM Optimization: Compiled to efficient machine code
• Precise Error Reporting: Error messages with file and line information

Getting Started

# Build the compiler
cargo build -p phoenix_runtime -r
cargo build -r

# Compile a Phoenix file
./target/release/compiler --input program.px

# Run the compiled program
./output/output

(Currently only tested on mac)

Project Status

Phoenix is under active development. Recent additions include:

• Vector support with push and indexing
• Span-based error reporting
• Return statements
• Multiple print function variants

Roadmap

• String as a first-class type
• Multi-file support
• Structs and classes
• Logical operators (&& and ||)
  • a && b: If a evaluates to false, b is not evaluated, and the result is false.
  • a || b: If a evaluates to true, b is not evaluated, and the result is true.
• Functions as variables
• Package management
• REPL
