Pry Programming Language

Pry is a simple, elegant, statically typed and compiled programming language implemented in Zig, with support for variables, control flow, functions, and code generation using LLVM.

Building and Running

1. Ensure you have Zig and LLVM installed on your system.
2. Run the compiler on an example file: zig build run -- examples/8.pry
3. Link the generated object file to create an executable: cc output.o
4. Run the executable: ./a.out

Language Features

• Variables and Declarations: Uses let for variable declaration.
• Control Flow: Supports if and while statements.
• Functions: Supports function declarations with parameters and return types.
• Expressions: Includes additive, multiplicative, equality, and unary expressions.
• Code Generation with LLVM: Translates AST to LLVM IR and generates object files for native execution.
• Import System: Allows importing libraries and other Pry files.

Example Program

let main = () => i64 {
    let fib = (n: i64) => i64 {
        if n == 0 {
            return 0;
        };
        if n == 1 {
            return 1;
        };
        return fib(n-2) + fib(n-1);
    };

    let result = fib(30);
    print(result);
    return result;
};
