If you have been following the svn commits you may have noticed a bit of activity on the js2 front.
I wanted to send a quick heads up that describes what is going on and invite people to try things out, and give feedback.
== Demos ==
The js2 extension and associated extension are ruining on sandbox-9. If you view the source of a main page you can see all the scripts and css and grouped into associated buckets:
http://prototype.wikimedia.org/sandbox.9/Main_Page
I did a (quick) port of usabilityInitiative to use the script-loader as well. Notice if you click "edit" on a section you get all the css and javascript, localized in your language and delivered in a single request. ( I don't include the save / publish button since it was just a quick port )
Part of the js2 work included a wiki-text parser for javascript client side message transformation: http://prototype.wikimedia.org/s-9/extensions/JS2Support/tests/testLang.html
There are a few cases out of the 356 tests were I think character encoding is not letting identical messages pass the test and a few transformations that don't match up. I will take a look at those edge cases soon.
The Multimedia initiative ( Neil and Guillaume's ) UploadWizard is a js2 / mwEmbed based extension and also enabled on in that wiki as well: http://prototype.wikimedia.org/sandbox.9/Special:UploadWizard
The js2 branch of the OggHandler includes Transcode support ( so embed web resolution oggs when embed at web resolution in pages ) This avoids 720P ogg videos displayed at 240 pixels wide inline ;) http://prototype.wikimedia.org/sandbox.9/Transcode_Test
The TimedMediaHandler of course include timed text display support which has been seen on commons for a while http://bit.ly/aLo1pZ ... Subtitles get looked up from commons when the repo is shared:: http://prototype.wikimedia.org/sandbox.9/File:Welcome_to_globallives_2.0.ogv
I have been working with the miro universal subtitles efforts so we should have an easy interface for people to contribute subtitles with soon
Edits pages of course include the add-media-wizard which as been seen as a remote http://bit.ly/9P144i for some time also now also works as an extension
== Documentation ==
Some initial JS2 extension is in extensions/JS2Support/README Feedback on that documentation would also be helpful.
