bad URL in instruction on how to build Unix VM from sources
by Jecel Assumpcao Jr 12 Aug '09

12 Aug '09

A friend of mine is trying to build Linux VMs in such a way that he can use the parallel port from Squeak with the library mentioned in http://tecnodacta.com.ar/gira/?p=144 He tried following the instructions in > http://www.squeakvm.org/unix/platforms/unix/doc/HowToBuildFromSource.html/H… but the server mentioned there no longer exists. I told him to replace squeak.hpl.hp.com with www.squeakvm.org in the URL and that worked. It would be nice if the page could be fixed since he is trying to create something that can be reproduced by many teachers in Uruguay who a pretty clueless about Squeak, much less about compiling VMs. Previously he had tried downloading the 3.7-7 sources from the link in http://www.squeakvm.org/unix/ but that doesn't include FFI by default. Patching generated file such as plugins.int didn't help and VMMaker (but the one included in Squeak 3.7 images and the latest one downloaded into a 3.10.2 image) refused to allow FFI to be dragged to either the internal or external plugin lists. The reason for trying 3.7-7 first instead of the very latest sources is that a change in character input introduced in 3.9-4 makes it incompatible with normal Squeak images (I imagine it works with Etoys images) if your keyboard has any "strange" characters. I just have to press "~" or something like that to get a debugger with new VMs. -- Jecel

Updating from Squeak3.10.2-trunk.image stops at 'Merging System ar.131'
by hannes.hirzel 12 Aug '09

12 Aug '09

Hello I am curious to see the on-going work towards a version 3.11 (in particular the new editor from CUIS and the fonts updates) So I took http://squeakvm.org/win32/release/Squeak-3.10.2-trunk.zip and http://www.squeakvm.org/win32/release/SqueakVM-Win32-3.11.3-bin.zip and hit the "Load code updates" button. The update process stopped . A window came up 'Merging System ar.131' (see screen shot) Is this the intended behavior? What am I supposed to do at this point? Thank you for this interesting work. I really like the font updates. The screen looks crisp and clear. Hannes

Winds of change
by Giuseppe Luigi Punzi 12 Aug '09

12 Aug '09

We have elections soon. I'ts time to think about the project. What we search? What new developers search? I think, probably, Squeak, needs a refactoring on the ideas behind. The people thath wants etoys, use etoys image. Croquet uses his own image. Now, at the moment (2009), I'm 90% sure, the people thath go to squeak.org, and get the latest Squeak, now, are developers searching a good smalltalk (something similar to VW but opensource I means) to use in their projects, not the use of Squeak as multimedia, or something similar. I know this for all spanish people ask me about Squeak, or developers "going out the list" searching Pharo, an approach to the things I say. I like the idea about a console squeak (like GST) with the objects living in memory, but not dependent of the "World", launching the actual Squeak World as an object (I don't know if is the actual behaviour, I only dream) if you want, or launching something like VW (or Dolphin) working over TK or GTK or WxWidgets or technologys like XUL instead.....I like the idea of an UI Painter....I like the idea of all Squeak tools running over web too..well, this idea don't like it very much :)..but I don't have the skills for all of this, for this I offer the ideas. But most important, is the community has vote for this things. The community needs to stay informed about the movements. I think, this, is the right direction. I don't know what you all think, but IMHO, it's the moment to get a new Squeak 4 from zero, trying to preserve the core classes, with new ideas and ambitions. I don't like very much the idea about all list hating me, but, after this mail, I know you hate me :P P.D.: Yes, probably, I'm crazy too.

Monticello Meta-information
by Ken Causey 12 Aug '09

12 Aug '09

Related to tracking licensing and tracking development status (as recently brought up by Bert) is there any support in MCZes for additional meta-information? If not, is there anything keeping us from adding an additional file to the archive for this purpose? Is any MCZ consuming software likely to be confused by an additional file? Ken

Class var order in Monticello (bogus dirty packages)
by Andreas Raab 12 Aug '09

12 Aug '09

Hi - I have noticed several times that Monticello sometimes reports a different order of class variables than the one that's in the image and I think I finally found out what causes it. The problem seems to be that the MCClassDefinition is constructed from a Set of class var names (i.e., Delay classVarNames => a Set(#TimerEventLoop #SuspendedDelays #TimingSemaphore #ActiveDelayStartTime #ActiveDelay #FinishedDelay #ScheduledDelay #RunTimerEventLoop #AccessProtect) derived from the class' classPool. The thing is, the order in that class pool can differ. When you add or remove class var names, the names can get shuffled around and there is no telling what the exact enumeration order will be. Once the order is different it's a real pain because Monticello will always report differences but without a way to correct the issue. I'm wondering what possible fixes might be. In particular considering that reordering the class var names will mark any packages dirty for the same reasons. Any ideas? Cheers, - Andreas

Squeak 4.x should adopt Pharo 1.0
by Keith Hodges 12 Aug '09

12 Aug '09

Dear All, As far as I see it the only sensible way ahead for squeak 3.11 is to adopt Pharo 1.0 as the next base version of squeak (i.e. 4.0), and to begin a series of initiatives to promote compatibility with squeak pieces that pharo doesn't support. The previous squeak 3.11 vision accepted, and now rejected, by the squeak board was to develop a process that would allow squeak to harvest the contributions of all the other forks, or other major initiatives, and for significant contributions to be shared by all the forks. All of a sudden there was an "oh no pharo is ahead of us" panic that ensued last month as a result of new squeak-dev people that were not involved in, nor seemed aware of the goals of the 3.11 process. Within this process Pharo may simply be viewed as a research project carried out on behalf of the wider squeak community, that will be harvestable in good time. However now that this idea is no longer going to be developed, we need to limit the number of diverging active forks as much as possible, rather than creating new ones ("trunk" makes the problem worse not better). Once the output of "trunk" is released in whatever form we will then have yet another base image to manage code for, and I don't think that that is an acceptable outcome. When it comes to the elections next year, if there is anyone who would like to run on the "Squeak to adopt Pharo" ticket, then I will vote for them. best regards Keith p.p.s. Bob is not going to be released as open source, if you would like the ability to build your images daily, and run the test suites against your deliverables, then please do email me for licensing terms.

Quick Morphic question
by Cees de Groot 11 Aug '09

11 Aug '09

Hi, I'm still as bad at Morphic as I used to be, so I hope you won't be offended by a simple question ;-). As usual, Morphic simply overwhelms me by its sheer amount of classes... I need something that contains a list of morphs, scrollable, that look mostly like StringMorphs (however, the individual morphs I like to be their own classes with their own behavior). The list needs to act like a parts bin so if someone drags an item, you get a copy of the selected morph at the hand to be dropped on some other morph (where the specific selected/dragged morph then executes its own particular behavior on the target). What would be the simplest setup? Thanks in advance, Cees

Services?
by Andreas Raab 11 Aug '09

11 Aug '09

Folks - I was looking through the trunk image to find potential unload candidates when I stumbled over the "Services" category. Am I mistaken or are services just not used anywhere? I was looking for any class refs etc. but it seems that all of this is self-referential and ultimately there is only WorldMenuProvider (which is mostly duplication of WorldMenu functionality) and BrowserProvider (which are just a few menus). What am I missing? What are services good for? Where are they used? Where should they be used? What is the motivation for including them in the base image? Thanks for any insights. Cheers, - Andreas
