Dart News & Updates

This is a blog post for Spanish-speaking developers who may be interested in learning Dart. Please pass it along to any Spanish-speaking developers you know! En su libro El programador pragmático , David Thomas y Andrew Hunt recomiendan "aprender al menos un lenguage nueva cada año." Bueno, es un nuevo año, y creo que ahora es un buen momento para aprender un nuevo lenguage. De hecho, si usted todavía no ha aprendido Dart, no hay mejor momento! El año pasado, empecé a estudiar español para poder compartir con todos los hispanohablantes del mundo mi introducción a Dart traducido al español. Después de pasar dos días delante de un micrófono tratando de no sonar como si tuviera canicas en mi boca, les presento a Esto es Dart ! Espero que les guste. In English: In their book The Pragmatic Programmer , David Thomas and Andrew Hunt recommend that you "learn at least one new language every year." Well, it's a new year, and now's a great time to learn a ...

Dart engineer  Bob Nystrom  has  posted the notes  from the December 17th language design meeting. He writes: Here's my notes from this week's meeting. It was a short one since we were mostly focused on M2: Configuration-specific code There's been some discussion among the language designers about this, but I haven't seen the details. Gilad says that libraries are parametric definitions. An import can define paramaters. The restriction is that these parameters have to be constants. Optional named params Lars says people are starting to nag him about a problem: sometimes with optional named parameters, you want to forward exactly what was passed. The language doesn't currently give you a way to do that without a combinatorial explosion. He asked Gilad if he can cook up some syntax where you can optionally pass a parameter. Cheers!

There are a number of name changes coming down the road in dart:html. Pete Blois  gives us the details :  FYI- We'll be renaming Window to WindowBase and LocalWindow to Window. Ditto for LocalHistory and LocalLocation. If you're curious, but not familiar it, there is both the global 'window' object, and IFrameElement.contentWindow. The contentWindow only exposes a subset of APIs while dart:html's 'window' exposes the full API. We used LocalWindow and Window to expose these two API sets, but LocalWindow was too undiscoverable. Hence, this change. As always, we invite you to join our  Dart mailing list , ask questions on  Stack Overflow , or file feature requests on  dartbug.com .

Mixins are a much talked about and anticipated feature of Dart and in a new article  Google engineer Gilad Bracha gives us details of plans to incorporate mixins into Dart in M3. Read about basic concepts behind mixins, the syntax and the semantics of mixins in Dart, issues surrounding privacy and statics, the extensibility of current proposals and what changes all of this brings to the language spec  : As always, we invite you to join our  Dart mailing list , ask questions on  Stack Overflow , or file feature requests on  dartbug.com .
