Muncher

Rust Stable Latest Version

About

An easy-to-use string muncher that allows easy tokenization when writing a parser. Muncher has peek and fork capabilities, so you can look ahead and behind when needed. If lexing braces, Muncher has a built-in brace matching stack accessed from Muncher::brace_stack().

Use

[dependencies]
muncher = "0.6"

Examples

use muncher::Muncher;

let input = "hello\nworld";
let mut m = Muncher::new(input);

let hello = m.eat_until(|c| c == &'\n').collect::<String>();
assert_eq!(m.peek(), Some(&'\n'));
assert!(m.eat_eol());
