Try inspecting "OSProcess thisOSProcess" and if the pid is nil, it means that you do not have the plugin. Dave

Comment #8 on issue 3784 by Torsten....(a)astares.de: ImageForDevelopers uses SHWorkspace which is not defined in the image http://code.google.com/p/pharo/issues/detail?id=3784 No, why wait for 1.3? It's fixed in "ImageForDevelopers-pharo-tbn.252" which is now in ConfigurationOfPharo-tbn.144 and should be in the next Hudson build then

[Pharo-project] Pharo on top of Flash plugin

by Alexandre Jasmin

>> Your image helps me a lot. >> >> I'm trying to get the Squeak VM compiling with Adobe Alchemy. > > tell us more :) I'm exploring ways to use Smalltalk inside a web page. There are already few interesting Javascript converters and Smalltalk inspired projects like the Clamato and the Lively Kernel. But it'd be nice to run unchanged code from Pharo or Squeak directly. The simplest way to bring Pharo on the web would be to run the existing VM inside a web page. The Squeak plug-in does that already but good luck getting anyone to install it. There are at least two solutions aiming to bring native code to the web without installing plug-ins - Google Native Client provides a sandboxed environment for x86 code - Alchemy (a research project at Adobe) compiles C into the bytecode language interpreted by Flash. Since Flash seems to have wider adoption than Native Client I'm doing a little experiment with it. I just took the VMMaker generated C code for the Squeak VM and passed it through the Alchemy compiler to get something that runs on top of the Flash plug-in. It's too soon to tell if this kind of nested VM is really usable. Performance will undoubtedly be an issue but I can at least run the Hazel image and have it beep in a loop which is encouraging. It seems Flash also supports some dynamic class loading which could enable performance improvements but the execution model while a bit better than Javascript doesn't really compare with Smalltalk. I don't see how we could support continuations for the debugger with pure AVM bytecode for instance. Anyways just recompiling the existing interpreter with Alchemy compiler requires a minimum of work so I'm focusing on that now. Will let you know how it goes.

Comment #7 on issue 3778 by fernando...(a)gmail.com: cleaning cursor: and cursor http://code.google.com/p/pharo/issues/detail?id=3778 Ok, i will go through the changset and load one by one. Until i find the probable conflicting change. pd: Pair programming like this has also been fun for me!

Comment #6 on issue 3778 by stephane...(a)gmail.com: cleaning cursor: and cursor http://code.google.com/p/pharo/issues/detail?id=3778 May be we should split the code in batch because probably it is changing something that is currently been executed.

I know it's probably not the sort of alternative you had in mind, but is anyone here interested in at least getting Pharo into Cydia? (Cydia is, among other things, the "app store" for folks who have jailbroken their iOS devices.) I'm sure several people would find it useful; it'd be a convenient way to get Pharo onto iThings and it would run with its full capabilities. -C -- Craig Latta www.netjam.org/resume +31 06 2757 7177 + 1 415 287 3547
