= Development Updates =

== Screaming Monkey ==

* how to complete stage 0 of screaming monkey? Having self-hosted compiler available would help Mark.  Compiler requirements are simple -- just be able to print.
* Jeff: Minimal self-hosting compiler available by end of month 
* Mark is working with just the abc files.  Not a blocking issue at the moment.
* Mark: working on scripting, need to figure out how to add extensions. status: engine is communicating but not doing much yet.

== Introductions ==

Quick introductions and areas of expertise:
* Lars Hansen: ES4
* Tom Reilly: garbage collection
* Jeff Dyer: compiler, self-hosting compiler (esc) author
* Brendan Eich: to blame for JavaScript
* Blake Kaplan: spidermonkey engineer
* Jason Orendorff: ActionMonkey
* Mark Hammond: python active scripting engine, ScreamingMonkey engineer
* Sanghyeon Seo: IronMonkey (working part-time, available more starting in September)
* Erik Tierney: compiler/VM engineer
* Dan Smith: Tamarin engineering mgmt

== IronMonkey ==
Seo has limited time to work on IronMonkey until September.

== Tamarin Goals ==

Brendan: Goal is to ensure Tamarin is small and fast enough to be the foundation for ECMAScript to start and then other languages.



== ECMAScript 4 Features ==

ECMAScript 4 Specification Status:
* Reference implementation available at [http://www.ecmascript.org ECMAScript.org]. Trac db for reporting bugs.  Wiki will be up soon.
* Lars and Francis Cheng working full time on specification.  Retiring TG1 wiki as we move to spec.
* Brendan: End of Sep is feature freeze ; want to implement a lot of ES4 in Tamarin

* Jeff Dyer: self-hosting work has been going on in monotone repository using ES4 RI.  Once it is self-hosting it will move to Tamarin.  Goal is to produce a subset of ES4 that can be hosted on Tamarin today.  Jeff is optimistic that compiler will be self-hosting before the end of August.

* Dan: Dick Sweet's Decimal support is ready for review and submission. Requires review from Rick Reitmaier, who is OOO until 8/20.

* Brendan: need to assess which features are least likely to change; additions to type system?  Probably won’t start fully on ES4 features until self-hosting compiler is available.

* Erik: status of generators.  Available in asc code base using only compiler changes. ES4 spec change means no constraints on GC when collecting generator.

* Leon Sha (not present): working on solaris port of Tamarin

== Other work ==

* Volunteer needed for 64-bit port.    
** Brendan: Johnny Stenbeck may be able to help out with 64-bit on Linux.
** Dan: Steve Harris may be able to help out as well.

* Volunteers: post to Tamarin-devel your experience.
