node Examples of use

const parseConfig = require("./utils/parseConfig");
const os = require("os");
const path = require("path");
const fs = require("fs");
const homedir = os.homedir();

let parseYarnConfig = parseConfig("#"," ")
let parseNpmConfig = parseConfig(";","=")

var str = fs.readFileSync(path.join(homedir,".yarnrc")).toString();
var str2 = fs.readFileSync(path.join(homedir,".npmrc")).toString();

var config = parseYarnConfig(str);
var config2 = parseNpmConfig(str2);

console.log(config);
console.log(config2);

Browser side usage examples

require([”./utils/parseConfig“],function(parseConfig){
    
	var parser = parseConfig("#"," ")
	var teststr=` #  Sample configuration file  #  This is a comment  cache "D:\\yarn\\cache" global "D:\\yarn\\global" `
	console.log(parser(teststr))
})
