syntaxe

A simple, declarative parser-combinator library.

lib.rs:

Memoir is a library of self-describing, reflective parser-combinators. Parsers are represented as reified objects that can print themselves as documentation.

For most purposes, syntaxe's prelude should be imported.

use syntaxe::*;

let parser =
    string("set").then(optional(symbol('!')))
    .then(whitespace())
    .then(string("on").or(string("off")));

assert!(parser.parse("set on").is_ok());
