To summarize: the Exupery VM has closure support for closure images,
use them and things will work ok. Don't try to use the JIT or you will
have problem (but you won't do that accidentally so you shouldn't
care).

Build, send and comment on Plugins page

There is a new page on the pharo website [1] with an overview
on all plugins available for squeak and pharo.

Plugins should be easily downloadable so one dont has to 
rebuild them from scratch again and again. This is especially
for newbies with no knowledge of the tool chain to build plugins.

Feel free to send comments and build/send plugins for the various
OS platforms. The page is maintained by m.rueger at acm.org 

Thank
Torsten

Re: [ANN] #10262cl

Why I love closures ;)

|tt|
tt := Transcript.
[1 to: 10 do: [:i | tt show: i printString; show: '*'.
					Processor yield ].
	tt flush	]  fork.
[100 to: 110 do: [:i | tt show: i printString; show: '-'.
					Processor yield  ].
	tt flush	] fork.

works and show that the transcript is bad :)

1*100-2101*-3*102-4*103-5*104-6*-7*106-8*107-9*-10*109-110-

Re: about the closure

So the semantics you describe is that the closure refers to variables  
until it is valued and not their values
And of course there is a difference whether the variable is a closure  
temporary or whether it is a enclosing scope one.

lukas is it normal that we get 3 tests yellow - did you get the same  
in your image?
Did you say it to eliot?

The tests of boris remind me some of my lisp cps-iterator :)
Ugly in smalltalk :)

That's a great start! Very useful potentially.

IMHO listing all the plugins that are usually built as internal is  
more confusing than helpful. At least that should be mentioned (or  
they should get their own table?). At the very least use a lower-case  
"i" to indicate "internal", I wondered what the vertical bar meant ;)

Plugins missing include Rome, DBus, GStreamer:

http://squeaksource.com/Rome.html
http://squeaksource.com/dbus.html
http://squeaksource.com/GStreamer.html

[ANN] #10262cl

When evaluating

  "ScriptLoader loadSuperOB"

in this image I'll get nil DNU #charCode in the Method UTF8DecomposedTextConverter>>nextFromStream:

(with both - the newest win32 vm from Andreas and 
the latest Exupery VM with closures).

Thx
Torsten

Build, send and comment on Plugins page

Hi Michael,

since I cross posted to squeak-dev, vm-dev and pharo-dev (yes I know
its bad) here some comments from Andreas and Bert from squeak-dev:

http://lists.squeakfoundation.org/pipermail/squeak-dev/2009-April/date.html

maybe you could add Rome, DBus, GStreamer

There is also DShowVideoDecoderPlugin for Webcams on Windows. 
DLL and link at:
http://www.is.titech.ac.jp/~ohshima/squeak/DShowVideo/index.html

And I remember a Win32FileDialogPlugin (the SAR includes the DLL):
http://kminami.fc2web.com/Squeak/Goodies/Win32FileDialogPlugin/index.html

Thanks
Torsten

[ANN] #10262cl

It crashes with the universe installer:
The web location has a ~ sign (unix server) in it with a 
previous / character:

So:

   'http://foo.bar/~test' asUrl 

will crash in printString now (see inspector)
while

   'http://foo.bar~test' asUrl 

will not.

Bye
Torsten
