Geoffrey Donaldson is working on a series of screencasts covering the new SproutCore 1.0 code base. He just posted the first episode, covering installing and creating your first app, on Vimeo. Give it a look and tell him what topics you’d like covered in the future.
The SproutCore dinner tonight was great. Thanks everyone who came. It was great to see/meet all of you. If you have pics, post’em and send’em our way. We’ll put them up.
Link: SproutCore WWDC Dinner + WebKit Party!
It's the biggest party night of the year for Clould application developers! Hang with SproutCore developers from all over the world for dinner followed by a party with other HTML5 ninjas at the annual WebKit party nearby. It's all part of the festivities surrounding the WWDC bash in SF.
Thanks to some recent additions to WebKit, method names in SproutCore apps now show up correctly in the profiler and debugger! Yay for better dev tools. And props to Francisco for contributing these improvements to WebKit.
To see these improvements for yourself, just get the latest WebKit Nightly and SproutCore 1.0 code. Then debug/profile to your heart’s content!
We did our final big postback yesterday for SC1.0. This postback includes a brand new refactored set of Controllers and a CollectionView. There’s a lot to dig into here, so let me start with one of my favorite features: Outlines.
Drawing an outline view is actually pretty tricky. For the most part, you’re simply displaying a list of items with some items indented more than others. SproutCore’s new CollectionView comes with support for inspecting a content array of items and rendering it as a tree, which is pretty cool.
Of course, usually your data structure for outlines is usually some kind of tree; not a flat list. Keeping track of all the nodes in this tree to generate the list can be fairly difficult.
Until now at least.
The new SC.TreeController in SproutCore 1.0 accepts a root node for any tree-like data structure and automatically generates a flattened outline list suitable for display in a collection view. It keeps track of changes to your data model and automatically updates this list as needed.
There are still a lot of bugs here - this is new code afterall - but I’ve put together a little demo app so you can see what I’m talking about. It’s called “Outline” and its available on our demo site here:
We’re still chasing down a perf bug in Firefox for this so I suggest checking it out in a Webkit browser for now. We’ll be publishing the code shortly.
Just another example of how SproutCore 1.0 can handle large amounts of data in the cloud with ease. (and without pagination!)
