Buffered Output

var logz = LogZ("basic", {
    env: "dev",
    showTrace: true,
    buffer: {
        size: 8,
        showTrace: true
    }
});

console.log("----------------------------------------------------------");
console.log("-- Log Output --");
console.log("----------------------------------------------------------");
logz.log("test");
logz.info("test: %s", "string");
logz.warn("test: %d", 123);
logz.error("test error: %d", 123);

logz.log("before group");

logz.group();
    logz.log("test log", "Group", 1);
    logz.warn("test warn", { obj: "Group1" } );

    logz.group("test 2");
        logz.log("test", "Group", 2);
        logz.warn("test", { obj: "Group2" } );
    logz.groupEnd();
logz.groupEnd();

logz.log( { after: "group", a: [1,2,3,4,5,6,7,8,9,0] } );

console.log("----------------------------------------------------------");
console.log("-- Dumping Buffered Output --");
console.log("----------------------------------------------------------");
var dump = logz.dump();

console.log("----------------------------------------------------------");

console.log("----------------------------------------------------------");
console.log( dump.join("\n") );

Custom Format

var logz = LogZ("basic", {
    display: true,
    formatFunc: function(lz, args) {
        var out = [];
        var a = 0;

        // add time
        var td = moment().format('YYYY-MM-DD HH:mm:ssZ');

        // if first arg is string add time to it to support % replacement
        if(typeof args[0] === "string") {
            out.push( "["+td+"] "+lz.name+" - " + args[0] );
            a++;
        } else {
            out.push("["+td+"] "+lz.name+" - ");
        }

        // add args
        for(; a < args.length; a++) {
            // if show time, and first item
            out.push( args[a] );
        }

        return out;
