DART language

I lamented Polymer.dart's JavaScript-y callback nature yesterday. But I didn't do much about it. Ultimately I cannot do much until the library matures into more of a Dart library. The Patterns in Polymer book needs to track the library, not my weakly ... [More] held, strong opinions (and I do admit that it makes sense to track the JavaScript Polymer for now). That said, I do think it worth exploring Dart futures as a means for cleaning up my tests. Last night's test looks like: group('syncing <input> values', (){ var... [Less]

Surprisingly, none of my Dart tests are failing. Or have failed. It's not that I expect Dart tests to fail with any regularity—far from it. It is just that the tests for the JavaScript version of Patterns in Polymer seem to fail every other week or ... [More] so. It probably helps that Polymer.dart has remained at 0.15 for a while now. I could also use some better tests. And since I went to all that trouble last night to write a test describing the JavaScript code from the chapter on synchronizing the plain-old form... [Less]

Today you can develop and deploy Dart server applications that run on the Google App Engine Managed VMs beta. The productivity of the Dart language and libraries are a great fit for server applications. You get the competitive performance of the ... [More] Dart VM while leveraging powerful tools like Observatory–all while easily sharing code with your browser application. Now you can try Dart on Google App Engine, which lets you build and run applications on Google’s infrastructure. App Engine applications are easy to build,... [Less]

I'm working on a game called "hakk.it".  hakk.it is 100% written in Dart and when launched, will be widely available as a modern web application for most devices that support the Chrome browser (I'm looking at you with a raised eyebrow IOS...).The ... [More] premise of the game is pretty simple, you write special software code called "hakks".  These hakks take physical form and combat each other in arenas.  In addition to code, the hakks are made up of different types of blocks, each of which the code can make use of in various ways. It's a... [Less]

Wow - Part One got a few visitors! Thanks for popping by - now on with Part Two. Seth Ladd from the Dart team dropped a comment on the code - you'll notice all fields are lower case now :-) This was an easy change thanks to Dart Editor's built in ... [More] refactoring. I have added more fields to the Chapter class and we can now create a chapter based on just the title. Named constructors coming in handy here. Two methods on Novel allow adding of Chapters and they return a reference for adding more details. [Less]

This is first in a series of blog posts where I will blog the creation of a simple writing tool as a Dart command line application. The background to this is NaNoWriMo which challenges anyone in the world to write a 50,000 word novel during November. ... [More] Luckily you are allowed to plan in advance (there is not last minute revealed theme or requirement). I started with pen and paper which has its benefits but is too static for my liking! In the past I have written presentation materials in Python to escape Powerpoint and don't want to live in a... [Less]

Today, JetBrains announced WebStorm 9, an update to their powerful web development editor. Highlights for the Dart developer include: pub serve support, improved isolates debugging, Observatory support, new syntax support, and more.WebStorm 9 now ... [More] launches pub serve, Dart's development server, when the developer runs a Dart web app. Pub serve takes care of generating assets, compiling to JavaScript, and more.Developing and debugging apps that run multiple computations in parallel is now easier, thanks to the new ability to set breakpoints inside of isolates.For deep insight into your app...

The Dart language, libraries, and runtime make it easy to create command-line applications. In fact, all of the core tools in the Dart SDK – dart2js, pub, and dartanalyzer – are written in Dart. We wanted to allow developers to easily get their own ... [More] Dart scripts and command-line apps into users' hands. With Dart 1.7, users now have an easy way to install and run scripts built with Dart, making first-class command-line Dart apps a reality.Developers can specify executables (Dart scripts)... [Less]

Today I've got some time to play with the new cedar-14 stack and the Dart buildpack, and I'm impressed on how easy it is now to deploy Dart apps on Heroku. Basically, to run on Heroku, your app must be configurable through environment variables. The ... [More] minimal configuration that every heroku application must handle is the port number, where the server is allowed to bind to. Let's see an example: import "dart:io"; import "package:redstone/server.dart" as app; //Import services here main(List<String [Less]

Many of our developers enjoy using lightweight text editors, but still want to use features traditionally found in powerful IDEs. Today, in partnership with Guillermo López-Anglada, lead developer of the Dart plugin for Sublime, we are announcing many new features to help Dart developers stay productive in Sublime Text 3.
