Experimental Fedora Core 5 packages
by Giovanni Corriga 10 Aug '06

10 Aug '06

Hi all, I've created some Squeak 3.9b RPM packages for the Fedora Core 5 Linux distribution. These packages are experimental, so I need some help in testing them and in fixing them according to the packaging rules of Fedora. Once they are reasonably bug-free, I want to submit them to a package repository (Fedora Extras if possible, otherwise a third-party one like rpm.livna.org). The packages maybe found at http://smalltalkit.seasidehosting.st/seaside/pier/RPMPackages . I'd like to thank Ian Piumarta, who kindly provided the templates I used for the .spec files, and also nasrat on the #rpm IRC channel, who helped me fix some bugs in my vm package. Giovanni

Proposal for a Squeak migration meeting
by Hilaire Fernandes 13 Jul '06

13 Jul '06

While at the 14th International Smalltalk Conference 2006[1], I am proposing we set a meeting during all the week to establish a migration plan to get the next version of Squeak released under a licence compatible with the free software community (probably APSL2 in our case). As a free software activist and developer, I always get political difficulty to promote Squeak because of its licence. For me it is already free but most of the free software community and my friend do not share this point of view. It is really a problem because most people get stuck to the licence problem and they can't discover all the great stuff coming with Squeak and Smalltalk. Getting the next Squeak released under a free software licence, compatible with the free software community, will help us if we want our community to grow, and we all fell the potential for the growth is there. A bigger community will be a great benefice for all of us: more people writing great library frameworks, developers could get more support from the free software oriented corporations, a well known Squeak will open new business opportunity, educators will be more exposed to Squeak and they will produce more teaching materials. In fact we will just be able to take benefice of the great promotion machinery of the free software community. Anyway I am just repeating things you already know. Back to the meeting idea. The only output of this meeting will be a migration plan, to establish wish bits need to be removed, rewritten, relicenced. It is more a meta-migration meeting than a migration meeting, but still it is a first step we need to work on. To establish a realistic migration plan, the helps of Squeak experts will be an absolute necessity. Great Squeakers as Marcus Denker, Stephane Ducasse, Adrian Leinhardt, Lukas Renggli, Mike Rueger (impara) will attend the International Smalltalk conference. We can take the opportunity of the physical presence of these experts to get great insights for a realistic migration plan. I am proposing for 4 or 5 days meeting, taking place after the daily conferences. The meeting could last for two hours, 17:00-19:00. As a matter of facts, which experts are ready to join such a meeting? Hilaire -- ADD R0,R1,R2,LSL #2

Patch request for 7036
by Pavel Krivanek 09 Jul '06

09 Jul '06

Hi Stef, can you put this two patches into the next 3.9a release? condenseChanges fix is related to http://bugs.impara.de/view.php?id=3737 - this patch doesn't solve all problems of condenseChanges routine but it's better than nothing. AsyncFile fix simply renames class variable named Error to ErrorCode. The first name collides with global class name. This will help me to update self-bootstrapping environment for Squeak 3.9 and make its public repository (http://www.squeaksource.com/KernelImage.html) usable. -- Pavel

SqueakMap: problems with ODBC package
by Torsten Bergmann 07 Jul '06

07 Jul '06

Hi, I want to install the ODBC package via script using Squeak3.9b#7035 SMSqueakMap default installPackageNamed: 'ODBC for Squeak' autoVersion: '2' This works but it loads an old version ODBC-dgd.1.cs.gz. The newest version ODBC-dgd.10.cs.gz is displayed below the first one in the SqueakMap package loader tree. Maybe this is caused by the similar registration with version number 1. When I try to load it using the package loader or by evaluating SMSqueakMap default installPackageNamed: 'ODBC for Squeak' autoVersion: '1' I get an error telling me that the file is not a gzipped stream. What's confusing is that the SM entry points to http://minnow.cc.gatech.edu/squeak/uploads/2480/ODBC-dgd.10.cs.gz and I can access the file when I use a normal web browser. It's also loadable after the download. Digging in the SqueakMap cache shows that it contains a file ODBC-dgd.10.cs.gz but this only includes the following text: "error occured retrieving http://minnow.cc.gatech.edu/squeak/uploads/2480/ODBC-dgd.10.cs.gz: Server minnow.cc.gatech.edu is not responding" Is SqueakMap having trouble due to the bad registration or is it a bug in the swiki file serving for uploaded files? Any ideas? Can we reregister the package? Thanks Torsten -- Echte DSL-Flatrate dauerhaft für 0,- Euro*! "Feel free" mit GMX DSL! http://www.gmx.net/de/go/dsl

TypeInference: File based way of thinking
by Damien Cassou 06 Jul '06

06 Jul '06

Hi, I'm currently interested in type inference. RoelTyper works by: - searching all messages that are sent to instance variables - searching all affections to instance variables I think this is the kind of things that can be done on file based languages (dynamically typed). But we are working with a live system with classes and their instances. It may be interesting to look at the instances of a given class and then get the type of the instance variable you want. If there are multiple instances of the class, we have to merge the results. Is it a good idea ?

DrGeoII, dynamic geometry for Squeak, released under LGPL
by Hilaire Fernandes 05 Jul '06

05 Jul '06

I am please to announce the distribution of DrGeoII, an interactive geometry framework for Squeak, under the LGPL http://www.squeaksource.com/DrGeoII.html DrGeoII is roughly based on previous DrGeo (http://www.ofset.org/drgeo) It is far to be finished, but it is already in a quite well polished and usable state.

Importing Visualworks code in Squeak
by Alexandre Bergel 05 Jul '06

05 Jul '06

hi! I would like to port Mondrian to Squeak. Mondrian is originally written in Visualworks. But when I extract the code from Visualworks, I obtain an XML description. Here is an excerpt: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= <?xml version="1.0"?> <st-source> <time-stamp>From VisualWorksÂ® NonCommercial, 7.4 of December 5, 2005 on June 26, 2006 at 5:26:50 pm</time-stamp>  <component-property> <name>MondrianDevelopment</name> <type>bundle</type> <property>developmentPrerequisites</property> <value>#(#(#bundle 'CodeFooDevelopment' ''))</value> </component-property> -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Is there an importer somewhere to load some code from visualworks into Squeak ? Nothing on Squeakmap and Squeaksource seems to correspond... Anyonw knows about Rosetta ? The work from Joseph...

Refactoring squeak
by Damien Cassou 03 Jul '06

03 Jul '06

Hi, sometimes when I dive into Squeak source code, I would like to refactor some piece of code that can be enhanced. Does someone care to have better source code in Squeak ? Where is the best place to post the enhancements ? To post new tests ? Often, it will be just one line or two, do I need to write bug reports in mantis ? Will somebody have a look at this ? Bye

Distinct echo in sound recordings on Mac OS X
by Murphy Stein 01 Jul '06

01 Jul '06

Hi All, I am want to record sounds using the SoundRecordingControls Morph but there is a distinct echo that I can't seem to get rid of. I made recordings with an alternate sound program (Amadeus II) and got fine recordings (apart from the crack of my voice :=), so I'm pretty sure squeak is doing something funny. Any idea if this is a known issue, or even how I might go about fixing it? I am using Squeak-Full 3.7 on OS X 10.4.6. Thanks, Murphy
