Seaside on VA Smalltalk?

Hi,

Watching the GLASS slides, it mentions that Seaside is available for
VA Smalltalk.

Where is it available?

Regards,

It doesn't. Slide 12 merely lists some other Smalltalk dialects. Slide
13 clearly states that it isn't available on VA.

It isn't however it should no longer be that hard to do. Continuations
are now only used for #call: and if you don't have continuations you
can use CPS.

Actually, in our presentation, slide #13 of
http://seaside.gemstone.com/GLASS-StS2007.pdf states that it is "not
available (yet)". The "(yet)" was added at the show after Instantiations
announced that Seaside support was part of their "roadmap." I don't know any
more than that. I don't see anything on the Instantiations web site.

That's not entirely true, continuations are still used internally.
They are just not cached any longer. That's why Seaside 2.8 has much
lower memory requirements. If somebody is interested we can maybe get
rid of the continuations all-together when no #call: and #answer: is
used.

Lukas, I'm interested in knowing how Seaside could remain valuable without
#call: and #answer? You replace it with what? How the statefull effect is
archieved without them? There are concrete future plans on this? Which will
be the trend?

Thanks,

Sebastian

I believe Lukas refers to using continuations only when #call: and
#answer: are used, not removing those methods entirely.

Exactly.

Seaside is still useful, even if the underlying plattform doesn't
support continuations, and #call: and #answer:. You can always
transform

    A.
    r := self call: aComponent.
    B.

into

    A.
    self show: aComponent onAnswer: [ :r | B ].

that does the same without continuations. It is ugly, but it works.
This is called Continuation Passing Style. Of course traditional
#call: and #answer: will be supported on all platforms that support
continuations.

Cheers,
Lukas

Does VA Smalltalk still exist?

Yes. It's no longer supported and maintained by IBM (except for the
S/390 platform), but it is now sold, supported, and developed by
Instantiations, who seem to be moving it along quite nicely.

Instantiation is looking how to support or implement Seaside
under VASmalltalk - that the message one gets from the
conferences or the VAForum in Frankfurt yesterday.

I like free beer too, that's why I posted the mail and didn't see the
slide 13 right after the 12. And kicked off a thread that deviated to
this :-D
