Dart Editor now analyzes as you type

A new Dart Editor build is available at www.dartlang.org/editor. Changes include:

• We now have analysis as you type! You're now alerted about errors as you type without first having to save the file.

• Debugger expression evaluation - when paused at a breakpoint in Dartium it's now possible to evaluate expressions. You can access this feature from the 'Show Expressions' toolbar button in the Debugger view. This is a Dartium only feature currently; support for the command-line debugger is forthcoming.
• We have two new quick fixes; one for creating a class and one for creating a constructor.
• Fixes for debugging command-line and Dartium apps when used with Pub and the packages directory.
• Tweaks to the @deprecated and @override presentation.
• And fixes to the cleanups, to our auto-update, for a debugger crash with Dartium, as well as 11 analysis fixes.

In addition, if you're running MacOS 10.8 (Mountain Lion), it will complain that our 64-bit distribution is corrupted. The net-net is that we need to sign our binary, but in the meantime two workarounds are to download our 32-bit build instead, or to change your security settings to let you run applications downloaded from anywhere.

And as always, view the changelog for the full list of changes, and to get started with the Editor see our tutorial.
