A fast, statically typed compiled language

Azula

Azula is a strongly-typed compiled language, using an LLVM backend, with the following goals:

• Static typing
• Easy-to-read syntax
• Efficient execution

Documentation

Discord

Origin

Azula started as a learning exercise through the Writing a Interpreter in Go and Writing a Compiler in Go books by Thorsten Ball. As I reached the end of the compiler, rather than expanding the VM for Azula, I decided compiling to LLVM would make the language far more usable. Rather than attempting to change the version written in Go, I decided to rewrite Azula from scratch in Crystal.

Goals

• Tokenizer
• Lexer
• Parser
• Compiler
• Write documentation in code
• Compiler Optimization
• Standard Library
• Self-hosting compiler

Compiling

azula build FILENAME

or to run directly:

azula run FILENAME

or to view the LLIR output:

azula llir FILENAME

Example Code

func fib(int x): int {
    if(x == 0 or x == 1) {
        return x;
    }
    return fib(x - 1) + fib(x - 2);
}

func main(): void {
    println(fib(15));
}
