This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.
To capture the video (filesize: 19MB), using the free "QuickTime Player" application:
| 'use strict'; | |
| module.exports = function CustomError(message, extra) { | |
| Error.captureStackTrace(this, this.constructor); | |
| this.name = this.constructor.name; | |
| this.message = message; | |
| this.extra = extra; | |
| }; | |
| require('util').inherits(module.exports, Error); |
