stacktrace.js v2.0 is out, featuring ES6 support, better stack frames, and more!
What (soundbar, headphones, 5.1 system) do you have?
: Dolby Digital Plus audio formatting featuring 6 distinct audio channels (5 surround speakers and 1 subwoofer).
The movie's plot revolves around a youngster named Advait (played by Aditya Roy Kapur) who falls in love with a woman named Sara (played by Disha Patani) while on a trip to Goa. However, their relationship faces challenges, and the movie explores themes of love, revenge, and redemption.
In the modern era of cinema, "WEB-DL" has become the gold standard for movie enthusiasts. Unlike "CAM" rips (recorded in a theater) or "HDRips," a WEB-DL provides a 1:1 digital copy of the stream. When Malang transitioned from theaters to Netflix, the "NF.WEB-DL" version became the most sought-after format because it allowed viewers to experience the film exactly as the director intended, without the compression artifacts often found in lower-quality uploads. Conclusion
: A seemingly righteous, straight-laced cop dealing with deep-seated personal issues that mask a sinister nature. Technical Analysis of the Format
If you'd like, I can provide a or more details on the soundtrack , which was a major highlight of the film's success.
More than meets the eye
5 tools in 1!
stacktrace.js - instrument your code and generate stack traces
stacktrace-gps - turn partial code location into precise code location
In version 1.x, We've switched from a synchronous API to an asynchronous one using Promises because synchronous ajax calls are deprecated and frowned upon due to performance implications.
All methods now return stackframes. This Object representation is modeled closely after StackFrame representations in Gecko and V8. All you have to do to get stacktrace.js v0.x behavior is call .toString() on a stackframe.
Use Case: Give me a trace from wherever I am right now
var error = new Error('Boom');
printStackTrace({e: error});
==> Array[String]
v1.x:
var error = new Error('Boom');
StackTrace.fromError(error).then(callback).catch(errback);
==> Promise(Array[StackFrame], Error);
If this is all you need, you don't even need the full stacktrace.js library! Just use error-stack-parser!
ErrorStackParser.parse(new Error('boom'));
Use Case: Give me a trace anytime this function is called
Instrumenting now takes Function references instead of Strings.
v0.x:
function interestingFn() {...};
var p = new printStackTrace.implementation();
p.instrumentFunction(this, 'interestingFn', logStackTrace);
==> Function (instrumented)
p.deinstrumentFunction(this, 'interestingFn');
==> Function (original)
v1.x:
function interestingFn() {...};
StackTrace.instrument(interestingFn, callback, errback);
==> Function (instrumented)
StackTrace.deinstrument(interestingFn);
==> Function (original)
Error: Error message

}
function bar() {

function baz() {
function showTrace(stack) {
var event = new CustomEvent('st:try-show', {detail: stack});
document.body.dispatchEvent(event);
}
function showError(error) {
var event = new CustomEvent('st:try-error', {detail: error});
document.body.dispatchEvent(event);
}
StackTrace.get()
.then(showTrace)
.catch(showError);
}
foo();

Turn partial code location into precise code location
This library accepts a code location (in the form of a StackFrame) and returns a new StackFrame with a more accurate location (using source maps) and guessed function names.
Usage
var stackframe = new StackFrame({fileName: 'http://localhost:3000/file.min.js', lineNumber: 1, columnNumber: 3284});
var callback = function myCallback(foundFunctionName) { console.log(foundFunctionName); };
// Such meta. Wow
var errback = function myErrback(error) { console.log(StackTrace.fromError(error)); };
var gps = new StackTraceGPS();
// Pinpoint actual function name and source-mapped location
gps.pinpoint(stackframe).then(callback, errback);
//===> Promise(StackFrame({functionName: 'fun', fileName: 'file.js', lineNumber: 203, columnNumber: 9}), Error)
// Better location/name information from source maps
gps.getMappedLocation(stackframe).then(callback, errback);
//===> Promise(StackFrame({fileName: 'file.js', lineNumber: 203, columnNumber: 9}), Error)
// Get function name from location information
gps.findFunctionName(stackframe).then(callback, errback);
//===> Promise(StackFrame({functionName: 'fun', fileName: 'http://localhost:3000/file.min.js', lineNumber: 1, columnNumber: 3284}), Error)
Simple, cross-browser Error parser. This library parses and extracts function names, URLs, line numbers, and column numbers from the given Error's stack as an Array of StackFrames.
Once you have parsed out StackFrames, you can do much more interesting things. See stacktrace-gps.
Note that in IE9 and earlier, Error objects don't have enough information to extract much of anything. In IE 10, Errors are given a stack once they're thrown.
