Tim Rowledge's explanation of VMMaker is here: http://wiki.squeak.org/squeak/2105 You will also find detailed instructions for VM builders along with the platform source code, which is maintained in a Subversion source code repository at squeakvm.org: http://squeakvm.org/cgi-bin/viewcvs.cgi/trunk/platforms/ For example, documentation on building for Unix (Linux) will be found here: http://squeakvm.org/cgi-bin/viewcvs.cgi/trunk/platforms/unix/doc/HowToBuild… And for Windows: http://squeakvm.org/cgi-bin/viewcvs.cgi/trunk/platforms/win32/docs/?rev=2147 which points to: http://squeakvm.org/win32/ And for Mac OS: http://squeakvm.org/cgi-bin/viewcvs.cgi/trunk/platforms/Mac%20OS/vm/Documen… as well as other documents that John mentioned in his reply. In other words, after you download the platform source code from the Subversion repository, you will find detailed documentation in the subdirectory for each of the major platforms. There is also a mailing list for the VM: http://lists.squeakfoundation.org/mailman/listinfo/vm-dev Dave

I ran FixUnderscores on package SystemTracing and saved it on SqueakSource as SystemTracing-dtl.12, so I think this should load now. Dave

Btw I can't come up with a language that changed > it's core library function names to shorter ones. The very same natural language argument can be used in favor of my point as well :) That is, if you *really* want to mimic the entire bandwidth of natural language, you should also mimic the tendency of natural languages to introduce abbreviations for common concepts. This is an *essential* part of any natural language. What should be said is that one should use whatever works best for himself. But a language that does not offer abbreviations to those that seek for them can IMHO not be called natural. The "huffman coding" presented in Akira's paper introduces shorter *aliases* for common methods. So you can pick and use what you want. So his paper is exactly about how they proceed when introducing short aliases in the evolution of the Ruby API. The full paper can be found here http://www.citeulike.org/article/6174874 > Object >> #p is not really useful. Logging to Transcript is a bad practice > anyway. Print-outs are not *per se* bad practice. They have their justification and should be part of anyones debugging tool set. So even if you dont agree with abbreviating print-out to #p, you should not ban them from you tool set! For example, nothing beats print-outs when you need to trace a feed of events. You would not want to put an #inspect inside a loop that is taken 10'000 times :) Speaking of loops, I changed #h to abbreviate #haltOnce rather than #halt. At least for my style of debugging, that proofed to be more useful. I won't comment on the rest, some prefer concise language, some like to keep it verbose. My point is that a language should offer short aliases for common terms, and I guess all of my examples are common enough to qualify for a shorter aliases based on that criterion--if you want to mimic the evolution of abbreviations in natural language. --AA

The fact that the actual changes are in a method makes it a bit hard to browse (I like to browse things before installing them) Only problem is how to subscribe to a new window announcer when it pops up by any means (world menu, button, do-it....)? Should I scan World submorphs periodically? It does not seem right. Perhaps an announcement is missing in World, to notify a new window (then one can subscribe to the window) > A number of people already expressed their need for such an extension. > > Cheers, > Alexandre > > <MOMorphicExtensionInstaller.st> > On 4 Jan 2010, at 17:20, Gary Chambers wrote: > >> Nothing like that currently or previously AFAIK. >> >> Regards, Gary >> >> ----- Original Message ----- >> From: "Simon Denier" <Simon.Denier(a)inria.fr> >> To: "Pharo Development" <pharo-project(a)lists.gforge.inria.fr> >> Sent: Monday, January 04, 2010 4:00 PM >> Subject: [Pharo-project] Notifications of windows opening/closing/focus >> >> >>> Hi >>> >>> How do you get notified of windows opening, closing, or getting focus in >>> Pharo?

But it would be nice to get a clear pictures about how to build the VM and how the codes are structure in case I need to get in there. Personally I think the thing to do is expose the native library calls via FFI or Alien, then build the messy frame work for dealing with the library in smalltalk. Take a look at the GStreamer api I did in EToys for OLPC, or the Navigation services or quicktime stuff in Sophie. Or you can cheat a bit and also do most of the work in SLANG, see the Mac Menu Bar plugin as an example. Most code in SLANG with some cCode: for the api calls. =========================================================================== John M.

Ok, for the os-x the build instructions are here http://squeakvm.org/cgi-bin/viewcvs.cgi/trunk/platforms/Mac%20OS/vm/Documen… If you want to build the os-x V5 beta version, then get the SVN tree from here http://svn.isqueak.org/vm/ and build the SqueakPureObjc.xcodeproj For linux http://squeakvm.org/unix/ That all precludes the install & setup of VMMaker, but I always view that as the *easy* part.

There is a bug in there some where. Some people report it work, it works here, but then sometimes it does not work. I'll devote some time to it later tonight.

The VM is given documents to open when it launches and later when you do things like drag and drop, or double-cllick an image. It has to open the first image it sees, it has to pass on other documents for processing by the startup logic or drag or drop. Or it has to decide the document is an image file and we've one open already so we need to launch another virtual machine process to open the image the guy want's open.
