[ANN] SwaLint
by Tobias Pape 13 Mar '09

13 Mar '09

Dear Squeak community, we would like to announce the first release of SwaLint. SwaLint is a Squeak source code linting tool in the spirit of (C) Lint or SmallLint. It is intended as a developer aid to * test source code for stylistic coherence and * identify possible errors. It has been developed by Johannes Dyck, Christoph Neijenhuis, Tobias Pape, Nico Rehwaldt, and Arian Treffer during a course on software engineering held by the Software Architecture Group at the HPI, Potsdam, Germany. SwaLint is available from SqueakMap. Documentation can be found at http://swalint.netshed.de/. Tobias Pape on behalf of the SwaLint team

Apology for offensive spam on annoncements list
by Ken Causey 04 Feb '09

04 Feb '09

I apologize for this coming through on the announcements mailing list. I hope everyone realizes that I did not send this. Several copies were received purportedly 'from' various community members. With the announcements list I have had a policy of moderating all messages, even those from subscribers. But in the last year or so I had begun to relaxen this somewhat by whitelisting anyone who sent messages regularly, this included myself. Clearly this was a mistake and I will now remove myself and everyone else from the whitelist and I will have to go back to moderating every single message. Again, my apologies, Ken Causey -------- Forwarded Message -------- From: Lawrence Auster <ken(a)kencausey.com> Reply-To: ken(a)kencausey.com To: announcements(a)lists.squeakfoundation.org Subject: [Squeak Announcements] Obama -- The Judas Goat Date: Sun, 25 Jan 2009 17:52:47 +0100 Obama -- The Judas Goat 1/25/2009 By David Duke

Scheme continuations vs Squeak continuations
by Stéphane Rollandin 04 Feb '09

04 Feb '09

hello list, I realized yesterday that my scheme implementation in Squeak failed to evaluate properly the so-called "mondo bizarro" code: (let ((y (call-with-current-continuation (lambda (c) c)))) (display 1) (call-with-current-continuation (lambda (c) (y c))) (display 2) (call-with-current-continuation (lambda (c) (y c))) (display 3))) ... which should display "11213" instead, it writes "11" then goes on forever printing "2" I wrote the equivalent code in Smalltalk: y _ Continuation currentDo: [:c | c]. Transcript show: 1. Continuation currentDo: [:c | y value: c]. Transcript show: 2. Continuation currentDo: [:c | y value: c]. Transcript show: 3. and it appears the (wrong) behavior is the same. is anyone expert enough in continuations to help me fix this ? (the Continuation class used here is from Seaside) Stef

Problems with FFI, SqueakDBX and MacOS
by Mariano Martinez Peck 02 Feb '09

02 Feb '09

Hi people: I am asking for help with squeakDBX in mac. Yes, I am one of the developers, so ? heheheheh The thing is that Michael Atkisson is trying to getting working and have problems. As I know very little about mac, I ask for help. The problem is that FFI is not founding the openDBX library. The error is the famous "unable to find function address'". This is his enviorment: - Image: the 201 core, updated using the system update. - Squeak vm: 3.8.18beta3U.app - OS: Mac osx 10.5.6 - FFI instaled from here: http://map.squeak.org/accountbyid/cf58c358-46ee-465e-b6db-2740e9b32a53/file… - DYLD_LIBRARY_PATH="/usr/local/lib/:/usr/lib" ..... - PATH=/usr/lib:/usr/local/lib:other entries .... - Check the property SqueakPluginsBuiltInOrLocalOnly in Info.plist de la VM was in true but changed to false. - The ls of the directories of /usr/local/lib and /usr/lib are above. - We also try to put the openDBX library in the directory where is the VM or the image, but the same. - I read this: http://wiki.squeak.org/squeak/5846 Is this true ? I mean, FFI doesn't support dylib ? what can I do in this case ? Thanks for all the help you can give us.

Conference details: http://www.esug.org/Conferences/2009/Student+Volunteers Where: Brest, France When: August 31 - September 4, 2009 (saturday 29 if you want to participate to the smalltalk camp) What: Esug 2009 - a gathering of industry, academia, and other Smalltalk enthusiasts. http://www.esug.org/Conferences/2009/ .

squeak on unix and ucs4 key codes
by Martin Kuball 31 Jan '09

31 Jan '09

Hi! Can someone please tell me how to make squeak play nice with the keyevents generated by the new unix VM. I'm really fed up with this "subscript is out of bounds" error messages (where subscript is <= 0). I don't care if it is some change in the smalltalk code or if I have to disable something in the c-code before compiling. Martin

OB Package Browser and Shout Workspace
by Daniel Klein 30 Jan '09

30 Jan '09

I installed these from SqueakMap but I can't figure out how to start them. They don't appear in the World > open... menu and I can't find them in the System Browser. I'm on Windows running Squeak3.10.2-7179. Could it be that these are not compatible with my Squeak version? How do I get older Squeak VMs (like 3.9 and 3.7) if I need them? Daniel Klein
