stacktrace.js v2.0 is out, featuring ES6 support, better stack frames, and more!
Priyamaana Thozhi (2003) is a hallmark of Tamil cinema's family drama genre, exploring the rare and often misunderstood dynamic of platonic friendship between a man and a woman. Directed by and produced by the prestigious AVM Productions , the film remains a notable entry in the filmographies of stars R. Madhavan , Jyothika , and Sridevi Vijaykumar . The Core Narrative: Friendship vs. Societal Norms
The conflict deepens when Julie falls in love with (Vineeth), a cricketer competing for a spot on the Indian national team—a spot for which Ashok is the primary rival. In a dramatic test of friendship, Michael’s father demands that Ashok sacrifice his cricketing dreams and sever ties with Julie to ensure Michael's success and marriage. Ashok agrees to these conditions secretly, leading to a series of emotional misunderstandings before a final reconciliation. Cast and Crew
The story revolves around (Madhavan) and Julie (Sridevi), childhood best friends whose bond is entirely platonic. Their lives take a turn when Ashok marries Nandini (Jyothika), a wealthy woman who initially struggles to understand the intensity of Ashok and Julie's bond but eventually comes to respect it.
The film's success as a "feel-good" family entertainer is attributed to its balanced performances and technical team: Priyamana Thozhi (2003) - Plot - IMDb

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)

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.
