Dart Team Updates for April 2013

New Dart Editor Build With Enhanced Refactoring Support

Notes from the April 22 Dart Language Design Meeting

elvis operator / safe navigation operator Lars is fine with the idea of adding some syntactic sugar like this if it helps real users. Kasper thinks we should wait until after 1.0 to look into it since we'll need analyzer support, editor support, tests, etc.

New Dart Editor Build with Run Last Launch Option

Pub&#39;s New Constraint Solver

TL;DR: Pub now has a new constraint solver that will pick versions of packages that work with your SDK. No more "doesn't work with your SDK " errors. This should appear in your life in the next SDK build. Pub's job is to look at your dependencies and select the best versions for them.

New Quick Videos on Dart&#39;s Classes, Exceptions, and More

Goodbye InvocationMirror, Hello Invocation

TL;DR: We added a class Symbol to dart:core, renamed the class InvocationMirror to Invocation (keeping it in dart:core ), and moved Invoke.invokeOn to InstanceMirror.delegate (moving this functionality from dart:core to dart:mirrors ). Furthermore, Function.apply and InstanceMirror.invoke take a Map to represent named arguments. Finally, dart:mirror uses Symbol instead of String to represent names.

List of Last Minute M4 Breaking Changes

The M4 release saw the Core, Async, and Collection libraries stabilize. Dan Grove has compiled a list of the last minute breaking changes: The separator argument in Iterable.join defaults to "" (instead of `null`). All DateTime constants are non-abbreviated. Also changed DAYS_IN_WEEK to DAYS_PER_WEEK.

Core libraries stabilize with Dart&#39;s new M4 release

New Dart Editor Release with Dedicated WebGL Library

A new Dart Editor build is available at www.dartlang.org/editor. Changes include: New preference to disable auto-activation of code completion. Theme preview works with new analysis engine. Many performance and memory improvements with new analysis engine. Existing base64 encoder method CryptoUtils.bytesToBase64(List bytes, [int lineLength]) is changed to CryptoUtils.bytesToBase64(List bytes, {bool urlSafe : false, bool addLineSeparator : false}) Remove the (long deprecated) List.addLast method.

Enum Proposal for Dart

The contents from the post: Rumor has it that people want enums in Dart. We've been looking at how to do this for a long time. We've examined all kinds of variations; the full account is, like the giant rat of Sumatra, a story the world is not yet ready to told (forgive me, Sherlock, but I couldn't resist).

Why Blossom is Switching to Dart

So what motivated us to switch to Dart? In this post I'll try to answer this question and go into how I see Dart as a huge step forward for the web & mobile development ecosystem. Blossom is a lightweight project management tool for people who craft modern mobile and web applications.

Examining mechanisms to suppress warnings and checked mode when needed. Liberalizing function subtyping. Develop synchronous mirror API for introspection. remove deprecated Arrays, Date and StringBuffer.add/addAll/addCharCodes.

Why dart2js produces faster JavaScript code from Dart

The dart2js compiler, which converts Dart to JavaScript, now produces smaller and faster code thanks to its global type inferencer. By analyzing the entire program, the compiler can eliminate bail outs and redundant checks, resulting in code that runs faster on modern JavaScript engines.

Developers frequently ask me if Dart is ready for the real world. Well, of course, that depends on the application. Check out this short video in which Joe Fernandez and I not only show that Dart can be used in the real world, we also show that it can be used to take the tedium out of watering your lawn!
