Dicer

version 1.0.1

About

A simple library for evaluating strings representing dice rolls in rust. Dicer uses an LL(1) grammar and a recursive descent parser to parse strings and simulate randomly rolled dice. See grammar.md for examples of valid strings.

Example

```rust use dicer::eval;

fn main() { // simple expression let test = String::from("1d20 + 4 + min([2d4-MAX], 3) {3}"); println!("parse: \"{}\"\n", test);

let result = eval(&test).unwrap();
for res in result {
    println!("{} = {}", res.str, res.value);
}

} ```

output: ``` parse: "1d20 * (3+2) + min([2d4 - MAX], 3)"

(6) * (3 + 2) + min([ (3 + 1) -3 ], 3) = 31 ```
