My Ajax Experience West keynote covers a lot of ground, with slant-wise truth telling the over-arching theme. Mozilla believes in fairly radical open source action, including open strategy. In that spirit, three new projects, the first already known via jresig:
ActionMonkey, the project to join forces between SpiderMonkey and Tamarin, being driven by Jason Orendorff with Edward Lee and some old-timers and newcomers lending a hand. The first stage of development integrates MMgc into SpiderMonkey as a replacement for SpiderMonkey’s GC. (NB: the wannabe mascot has a day job.)
IronMonkey, the project to map IronPython and IronRuby to Tamarin, so that Tamarin becomes multi-lingual, over time delivering high performance for all languages. This effort is being spearheaded by Seo Sanghyeon (whose last name I apologize for misspelling — or for using a different spelling of, at any rate — in my slides). The idea is to make use of the MsPL-licensed open source that Microsoft has kindly given the world, and tend necessary changes or additional code in downstream truly-open repositories that can accept patches from non-MS employees, such as FePy.
ScreamingMonkey, the project to add browser-specific script-engine glue to Tamarin, enabling it as a <script> tag handler in other browsers, starting with IE. Mark Hammond is leading this charge. Where it will end, one can only speculate. At a minimum, if you have Tamarin installed on your system in the future, you may need only a small download to plug it into other browsers. Best case, it comes with all the relevant glue in its main distribution. We’ll see.
