Emit and/or format raw stacktraces when errors are thrown
Get raw stack traces when errors are thrown.
Optionally customize the format of stack traces.
node-raw-stacktrace works by hooking into v8's prepareStackTrace call. v8 calls this function when code accesses the Error.stack property to render it to a string.
This means that Error.stack needs to be accessed or events will not be emitted. Usually this is not an issue if it gets logged to a file or stdout, but it's something to keep in mind.
var raw = require'raw-stacktrace';
EventEmitter that emits an array of either raw or formatted
CallSites. You can read about v8's CallSite API here
opts may contain:
true if you just want the raw array of callsites,
false, the callsites are formatted to objects.
formatter: [optional] a
function(err, callsites) that formats stack
traces, usually returns a string but it doesn't have to.
