Make MOJavascriptObject.h as public headers in Build Phases
Build project and we will get CocoaScript.framework
Copy CocoaScript.framework to your Xcode project

Define the objective-c methods with callback

Using OS X as a Syslog Server

This document describes how to set up an OS X to be a syslog server that logs messages from the local network. It was largely meant for my own purposes so that I don't forget what I did, but feel free to use it for your own purposes.

A problem with just "turning this on" is that you will not see the correct hostname in the syslog entries. What we will do is use

This is what Craft does:

function loadFramework(pluginRoot) {
  if (NSClassFromString('PanelsManager') == null) {
    var mocha = [Mocha sharedRuntime];
    return [mocha loadFrameworkWithName:'Panels' inDirectory:pluginRoot];
  } else {
    return true;
 }

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

Comparing ES7 and core.async

ES7	core.async
`async function() {...}`	`(fn [] (go ...))`
`await ...`	`(<! ...)`
`await*` or `Promise.all(...)`	`(doseq [c ...] (<! c))`

	const critical = CharacterSet.parseUnicodeRange('U+00-A0,U+A9,U+AE,U+B2-B3,U+B9,U+2013-2014');
	const all = CharacterSet.parseUnicodeRange('U+0000-FFFF');
	const inverseOfCritical = all.difference(critical)

	console.log(inverseOfCritical.toHexRangeString())
	// => U+A1-A8,U+AA-AD,U+AF-B1,U+B4-B8,U+BA-2012,U+2015-FFFF
