Crate koto

Koto

Pulls together the compiler and runtime for the Koto programming language.

Programs can be compiled and executed with the Koto struct.

Example

use koto::prelude::*;

let mut koto = Koto::default();
match koto.compile("1 + 2") {
    Ok(_) => match koto.run() {
        Ok(result) => match result {
            KValue::Number(n) => println!("{n}"), // 3.0
            other => panic!("Unexpected result type: {}", other.type_as_string()),
        },
        Err(runtime_error) => {
            panic!("Runtime error: {runtime_error}");
        }
    },
    Err(compiler_error) => {
        panic!("Compiler error: {compiler_error}");
    }
}
