function getfileline(stacklevel) {
var index = stacklevel || 2;
var stacklist = (new Error().stack).split('\n')[index];
// regexps borrowed from "tracer" in npm
var stackReg = /at\s+(.*)\s+\((.*):(\d*):(\d*)\)/gi;
var stackReg2 = /at\s+()(.*):(\d*):(\d*)/gi;
var sp = stackReg.exec(stacklist) || stackReg2.exec(stacklist);
var result = {
func: sp[1],
filename: path.basename(sp[2]),
fullfile: sp[2],
path: path.dirname(sp[2]),
line: sp[3]
return result;
