stacktrace.js v2.0 is out, featuring ES6 support, better stack frames, and more!
A more technical discipline included in the FX and later editions.
An adrenaline-pumping challenge where balls are added to the table over time; you must clear them before the table becomes too crowded.
Developed using Unreal Engine , the game features photo-realistic environments ranging from chic modernist lounges to neon-soaked nightlife venues.
A creative mode allowing players to build elaborate Rube Goldberg-style trick shots using ramps, loops, and speed strips. Pool Nation FX Lite on Steam
Players can unlock and personalize their experience with over 44 unique cues , various ball sets, and custom table decals. Diverse Game Modes
Balls react to spin (English), pressure, and cushions exactly as they would on a physical table.
One of the reasons for the game's longevity is its sheer variety. It moves beyond standard 8-ball to include:
At its heart, Pool Nation is built on a designed to mimic real-world ball behavior with pinpoint accuracy. Whether you are a casual player looking for a relaxing evening or a serious competitor aiming for the American Poolplayers Association level of skill, the game offers a scalable challenge.
The classic experience most players crave. 9-Ball & 3-Ball: Fast-paced variants for quick sessions.

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.
