Dicer

version 0.2.0

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() { let test = String::from("1d20 * (3+2) + min([2d4 - MAX], 3)");

println!("parse: \"{}\"\n", test);
let result = eval(&test).expect("uh oh");
println!("{}", result.value);
println!("{}", result.str);

} ```

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

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