[Xerte] Actionscript 3 version of Xerteandbackwardcompatiblitywith current versions

Wed Aug 19 14:04:55 BST 2009

Xerte 3.0 will not support Xerte 2.5 .rlo files, no. Support for 2.5
will remain as it is, and if anything were to change I would hope to
signpost that way in advance. 2.5 is now very mature, very few changes
have happened inside the engine for the last 12 months.

I'm not sure. ;-)

I had looked at the beta and noticed a number of tag name changes and
outright drops. Opened a basic .rlo just for fun and while it opened
there are obvious gaps.

I guess I'm just asking if the current public runtime and editor is
considered "mature". i.e. any further changes to them will be community
based and nothing created using them will be portable to 3.0 and beyond.

The runtime engine is inherently different. It is built on the Flex
framework, which brings an awful lot of out of the box power vis a vis
developing the whole thing from scratch in AS3.0. The interpreter is
different, so the scripting language changes a bit. Overall the
application is very similar. I have built what's there so far using
FlashDevelop, which I like a lot, and everything is now much more
object-oriented than before. This makes it a lot easier for the
community to contribute than it is currently, and also much easier for
us to manage contributions to the code base. As now, any contributions
would be very welcome - although the runtime engine is pretty good right
now - it is the editor that needs a lot of work. Certain editor
considerations might mean looking again at the .x3o file format which is
why things are very much 'for information' right now.

Does that answer your question?

Julian, so do you see a bifurcation in the development tracks, or will
dev on < 3.0 become community based?

Cheers,
Dave

Almost certainly there won't be backwards compatibility with .rlo files
- things are just too different.

Definitely there will be compatibility with toolkits data, which is just
data after all.

Things are still very embryonic. You can check out the samples in the
.svn, and can install a fledgling Xerte 3. There are still some quite
fundamental decisions to make on how best to take this forward, but
having said that you can already see how much more powerful it is.

Download it here:

not for any production work - just a preview of some work in progress.

Hello,

Anyone with access to the SVN has been able to see the beginnings of an
actionscript 3 version of Xerte for about a month or so. It's also been
listed on the wiki page for a while as well.

Toolkits is modularised and as such could happily run many different
editors and players as part of the same system (we've been playing with
a HTML play version over the last few days), but because Xerte 3 is in
it's very early days for its development, I can't really give any
specifics as to what it will and won't be able to do. 

It's worth noting that I am not working on Xerte 3 directly, as I don't
know any flex, and the answer above is mostly guess work as Julian's not
here.

If there are features you would like then please have a think about it
and let us know, or maybe even start a page on the wiki.

Pat

compatiblitywith current versions

Hello Xerte Team,

In my explorations through the archives I came across something Julian
posted on 22nd July 2008 regarding a Xerte 2.0 type application that
would use actionscript 3.0. 

In this posting Julian writes

> It would lead to a Xerte 2.0 type application that would actually

than

If I recall correctly Pat has mentioned in recent postings working on an
Actionscript 3.0 version of Xerte.

I was wondering how backward compatible this would be with the current
versions of Xerte / Templates / Toolkits, bearing in mind Julian's
comments from 2008.

Kind regards

Johnathan
