yieldparser VS parser-combinators

I’ve found generator functions work great for parsers. You yield the tokens you expect to be next. The token could be a string, a regular expression to be matched, or another generator function.

The library is open source here, contributions welcome: https://github.com/RoyalIcing/yieldparser

Generator functions have great support in modern browsers (not IE) and Node.js.

For example here’s a simple v4 IP address parser:

import { parse, mustEnd } from 'yieldparser';

function* Digit() {

Parser combinators [0] are great for quick parsing, usage from typescript is very neat. You can collapse tokenisation, parsing and some evaluation for simple grammars (they appear in production from time to time) into single parser combinator phase (there’s nothing else) where you get desired, typed result.
