more code description

We introduced code description last week, and noticed that having description is good. for many reasons.

For old codes, which are posted before we released the code description feature, we auto extracted comments before package definition as description.

We improved this auto-extraction logic to extract the document class comments which appear before the class definition, in addition to the already implemented package comments.

And, this auto-extraction will run for future codes too, only if you haven't set the description by yourself.
If you write the description by yourself, it'll stay there, but if you leave it blank, description will be auto-extracted from ActionScript3 comments.

So, it will look like this when you leave the description blank:


comments before the package definition, and the class definition will be shown under your code title.


先週、コードの description 「説明」機能をリリースしました。description機能は好評で、これを今回より強化しました。





WonderflUtils and wonderfl API

Not many of you might know, but wonderfl has APIs.
wonderfl API [wonderfl]

And there's an as3 wrapper library for it now.
WonderflUtils [github]

Thanks to bkzen for the contribution.
Go fork it on github and feel free to pull request or give us feedback.

Here's the test code for WonderflUtils
WonderflAPI Test [wonderfl]


More attractive thumbnails!

Thumbnails can be taken at any time!
The new capture button(camera icon) is placed below the preview SWF next to the reload button.
By pressing the button, thumbnail is captured immediately.

Now that you can take more aesthetic thumbanils to make your codes look more attractive!




let's write code description

From today, you're able to add a "description" for a code.

You might want to write:

  • some references, what inspired you to write it

  • how to interact with your Flash content

  • the core logic, any explanation about the code

  • any requests for other wonderfl users to fork and modify

  • what you think is cool about the code you wrote

  • .. or anything

HTML tags are not allowed but URLs will be auto-extracted as anchor tags.
We did some comment-parsing-and-extract-what-looks-like-description from past code, so some might already have description, but write it by yourself for future codes.





9/17(Fri) wonderfl, Meetup #1

The console looks like this:

signin using another OpenID or OAuth

Today, we released a feature which lets you use more than one OpenID or OAuth to signin as a single wonderfl user.

Until yesterday, if you signin using Google, signout, and signin using Twitter, you were a different wonderfl user.

But from today, you can use both Google and Twitter, and of course other authentication services listed up, to signin as the same "you".

If you already have posted codes, have favorites, or followers, all of them will transit to your first wonderfl user.

Visit and click on any authentication service and continue!

Useful when you're not sure about your brain memory!
Associate all authentication services and forget about which one to click.



wonderflはOpenID, OAuthを使ってログインが出来る仕組みになっており、それぞれのサービスでの認証情報が1つのwonderflユーザーアカウントと結びついていました(例えばGoogle OpenIDで認証してログインした場合とTwitter OAuthで認証してログインした場合は別のwonderflアカウントに)。


ログインした状態で にアクセスすると、プロフィール/編集設定の下にアカウント設定があります。


・今までGoogle OpenIDでログインしていたがFacebook OAuthでもログインしたい!
・基本的にTwitter OAuthでログインしたいけど念のため OpenIDでもログインできるようにしておきたい!
・ついGoogle, Yahooそれぞれ使って2つのアカウントを運用していたけど、この際だから1つのアカウントに統一したい!


LIVE coding Flash with CHAT feature

We added text chat feature in LIVE coding.

Ask questions while coding, chat about what you're going to create, maybe some kind of Flash e-learning?

Click on the LIVE button in the actionscript editor and try!
