Crate cbqn 

cbqn

A crate for running BQN code within a Rust program using CBQN interpreter compiled as a shared object or a WASI reactor.

Usage

Simple expressions can be run with the BQN! convenience macro. For more advanced use, the methods of BQNValue provide the necessary functionality.

Examples using the BQN! macro

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

assert_eq!(BQN!("⌽≡⊢", "BQN")?.to_f64()?, 0.0);

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

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

Examples using BQNValue

let sum = eval("1+1")?;
assert_eq!(sum.to_f64()?, 2.0);

let is_palindrome = eval("⌽≡⊢")?;
assert_eq!(is_palindrome.call1(&"BQN".into())?.to_f64()?, 0.0);

let split = eval("(⊢-˜+`׬)∘=⊔⊢")?;
let strs = split.call2(&' '.into(), &"Rust ❤️ BQN".into())?
    .to_bqnvalue_vec()?
    .iter()
    .map(BQNValue::to_string)
    .collect::<Result<Vec<String>, _>>()?;
assert_eq!(strs, ["Rust", "❤️", "BQN"]);

let counter = BQN!("{v←0 ⋄ Inc⇐{v+↩𝕩}}")?;
let increment = counter.get_field("inc")?.unwrap();
increment.call1(&1.into())?;
increment.call1(&2.into())?;
let result = increment.call1(&3.into())?;
assert_eq!(result.to_f64()?, 6.0);
