A recursive printing function, similar to PHP's print_r.

printR

var printR = function (obj, indent) {
    indent = indent || 0;
    if (typeof obj === "string") {
        grunt.log.writeln("'" + obj + "'");
    } else if (typeof obj === "object") {
        grunt.log.writeln("{");
        Object.keys(obj).forEach(function (key) {
            grunt.log.write(repeat(" ", indent + 2) + key + ": ");
            printR(obj[key], indent + 1);
        });
        grunt.log.writeln(repeat(" ", indent + 1) + "}");
    } else {
        grunt.log.writeln(obj);
    }
};
