Datejs – Date.isAfter – no such function ?

date.js – missing methods

Summary

Save yourself a lot of pain and ensure you’re using the right version of  Datejs.

Datejs – It’s great !

Let me start by saying that Datejs, an open-source JavaScript Date Library, is great ! It provides a lot of much needed functionality to the area of dates in Javascript.

Weirdly missing methods

Having said that what I want to highlight is that if you use the standard download links offered by the website (as shown below) you’ll get a version of Datejs which is not the most current one.

What’s more it seems that the version you will get contains a number of defects.

I can vouch for this as I’ve spent a couple of hours today wondering why the ‘.isAfter’ and the ‘.compare’ methods didn’t seem to exist in the form they are documented ! Very frustrating !

What You Should Do

Instead of using the download link on the first page to get the date.js file go here instead : http://www.datejs.com/build/date.js. The version number is the same, “1.0 Alpha-1″, but the build date is “2008-05-13″.

At least at the time of writing – it’s the “2008-05-13″ build you want.

Credit Where Credits Due

I’m grateful to Ben McIntyre whose post on the Datejs forums alerted me to this problem, I only wish I’d seen it earlier !

Ace ‘Editor in the Browser’ – Documentation

Ace ‘Editor in the Browser’ – Documentation

The documentation for Ace – where is it ?

Summary

The Ace documentation isn’t that hard to find but you do need to know where to look

Ace in the hole

The Ace project provides a customizable, embeddable code editor for web applications. It’s written solely in JavaScript and is really very impressive.

You can see it in action at their demo page (which frankly is a bit bare bones) or at the Cloud9 project for which Ace is the starting point.

Documentation is where ?

You can download the Ace distribution from https://github.com/ajaxorg/ace – you need the ‘Downloads’ button at the top right.

Once you’ve done that you’ll find there’s nothing worth reading in the docs folder within the distribution.

Instead what you need to do is go visit the Ace wiki at Github. It took me a while to work this out (with the help of the Ace user group forum) so I hope it will save some others the trouble.
