Strongtalk
Locked
 
|
I noticed this on the seaside site www.seaside.st
Seaside is not available for other Smalltalks at this time. Many Smalltalk VMs do not support the stack-copying techniques Seaside uses to implement backtracking. The status for various dialects is: . Smalltalk/X: not feasible . VAST: not feasible . Gnu Smalltalk: believed to be possible, but never tried . Ambrai: unknown Do you know if Strongtalk supports the stack-copying techniques Seaside uses?

I was under the impression Cincom's VisualWorks has a Seaside port.
Can anyone confirm this? -Mel Riffe On 10/4/06, Ron Teitelbaum <[hidden email]> wrote: I noticed this on the seaside site www.seaside.st _______________________________________________ Seaside mailing list [hidden email] http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside |

If at all possible it would be great if the people that know about these
techniques at seaside could work with your group to make sure that seaside is supported on your new VM.

Looking into their "Object Hierarchy", there {currently} is no accessor in Context and Block (incl. subclasses), nil, zippo, zero. But that doesn't say anything about the possibility of implementing support for Seaside's Continuation in Strongtalk. /Klaus > Ron Teitelbaum _______________________________________________ Seaside mailing list [hidden email] http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside |

"VMs do not support the stack-copying techniques Seaside uses to implement backtracking" I'd like to know where I can find information on these stack-copying techniques. I mean, how to check if a VM does support it? there are some key methods I should look for? thanks --- Ron Teitelbaum <[hidden email]> escribió: > I noticed this on the seaside site www.seaside.st > > Seaside is not available for other Smalltalks at > this time.

You should have a look at the Continuation class and its tests like
the Amb operator.

If you can copy/restore the stack, you should be able to implement continuations. In Squeak and VisualWorks, you can get your hands on 'thisContext sender' which you can decompose, save then (later) load, compose, swap in place of a current stack and proceed. See class Continuation for how it does it (#initializeFromContext: and #restoreValues among others).
Hope this helps, -Boris -- +1.604.689.0322 DeepCove Labs Ltd. 4th floor 595 Howe Street Vancouver, Canada V6C 2T5 [hidden email] CONFIDENTIALITY NOTICE This email is intended only for the persons named in the message header.

Hi Paul,
I took a look to see, I had not heard of Vista Smalltalk. I had the feeling that it was actually a copy of squeak, but now I'm not sure, http://vistasmalltalk.wordpress.com/2006/08/18/vista-smalltalk-and-its-cousi ns/ maybe someone at seaside knows if it will work with vista.
