Macro cbqn::BQN

macro_rules! BQN {
    ($code:expr) => { ... };
    ($code:expr, $x:expr) => { ... };
    ($w:expr, $code:expr, $x:expr) => { ... };
}

Convenience macro for running BQN expressions

Takes a string of BQN code and optional left and right argument

Examples

let sum = BQN!("1+1").unwrap();
assert_eq!(sum.to_f64().unwrap(), 2.0);

let bqn_is_anagram = BQN!("⌽≡⊢", "BQN").and_then(|e| e.to_f64()).unwrap();
assert_eq!(bqn_is_anagram, 0.0);

let strs = BQN!(' ', "(⊢-˜+`׬)∘=⊔⊢", "Rust ❤️ BQN")
    .and_then(|e| e.to_bqnvalue_vec())
    .and_then(|v| {
        v.iter()
            .map(BQNValue::to_string)
            .collect::<Result<Vec<String>, _>>()
    })
    .unwrap();
assert_eq!(strs, ["Rust", "❤️", "BQN"]);

let strings = ["join", "these", "please"];
assert_eq!(BQN!("∾", strings).and_then(|e| e.to_string()).unwrap(), "jointheseplease");
