Workshop on Dynamic Languages and Applications
by Bergel, Alexandre 31 Mar '07

31 Mar '07

Dear Squeakers, Dyla is a good venue to present and discuss ideas about Squeak, Smalltalk and dynamic languages in general. Do not hesitate to contact me for more information. Cheers, Alexandre ************************************************************************ ** Call for Papers Dyla 2007: 3rd Workshop on Dynamic Languages and Applications July 31, 2007, Berlin (Collocated with ECOOP 2007) http://dyla2007.unibe.ch ************************************************************************ ** Objective ========= The goal of this workshop is to act as a forum where we can discuss new advances in the conception, implementation and application of object-oriented languages that radically diverge from the statically typed class-based reflectionless doctrine. The goal of the workshop is to discuss new as well as older "forgotten" languages and features in this context. Topics of interest include, but are certainly not limited to: - agents, actors, active object, distribution, concurrency and mobility - delegation, prototypes, mixins - first-class closures, continuations, environments - reflection and meta-programming - (dynamic) aspects for dynamic languages - higher-order objects & messages - ... other exotic dynamic features which you would categorize as OO - multi-paradigm & static/dynamic-marriages - (concurrent/distributed/mobile/aspect) virtual machines - optimisation of dynamic languages - automated reasoning about dynamic languages - "regular" syntactic schemes (cf. S-expressions, Smalltalk, Self) - Smalltalk, Python, Ruby, Scheme, Lisp, Self, ABCL, Prolog, ... - ... any topic relevant in applying and/or supporting dynamic languages. We solicit high-quality submissions on research results and/or experience. Submitted papers must be unpublished and not submitted for publication elsewhere. Submissions should not exceed 10 pages, LNCS format (www.springer.com/lncs). Submission ========== Prospective attendees are requested to submit a position paper or an essay (max 10 pages, references included) on a topic relevant to the workshop to Alexandre Bergel (Alexandre.Bergel(a)cs.tcd.ie). Submissions are demanded to be in .pdf format and should arrive before May 13, 2007. A selection of the best papers will be made, which will require an extension for an inclusion in a special issue in Electronic Communications of the EASST (eceasst.cs.tu-berlin.de). For this purpose, a new deadline will be set after the workshop. Moreover, Springer publishes a Workshop-Reader (as in the case of previous ECOOPs) which appears after the Conference and which contains Workshop-Reports (written by the organizers) and not the position papers submitted by the participants. Important dates =============== Submission due: May 13, 2007 Notification of Authors: May 31, 2007 ECOOP'07 Early Registration Date: June 15th.

Hard Rock Cafe at Smalltalk Solutions
by Boris Popov 30 Mar '07

30 Mar '07

See the message from Travis below and if you're interested, I suggest you gather in groups and get touch with Crystal Watts who is a Sales Coordinator at Hard Rock Cafe SkyDome. I contacted her by email to make our reservation and she'd responded with a confirmation within a day, but if you're anxious you could probably just give her a ring as well, skydome_sales2(a)hardrock.com P: (416) 362-3636 ext. 206 F: (416) 362-9010 Cheers! -Boris -----Original Message----- From: Travis Griggs [mailto:tgriggs@cincom.com] Sent: Thursday, March 29, 2007 10:06 AM To: VW NC Subject: Hard Rock Cafe at Smalltalk Solutions Boris Popov was kind enough to arrange for 6 of us to have a table at the Hard Rock Cafe on the 30th. There's a game (Jays vs Texas) which can be viewed from the window tables. It's pretty cool. The thing is, the 6 of us are pretty arbitrary (the table sizes are 6), but we could think of about 20+ people probably who we know are going to StS this year. So we're hoping many others will choose to gather there too. Sorry we didn't do a big reservation, none of us are as brave anymore after Anthony Lander's experience from last year. :) Boris maybe you could chime in with the phone number? You could reply with interest to this thread, or possibly show up in irc.freenode.net#smalltalk. Hope to see as many there as possible. If someone could relay this to the Squeak list, and any other Smalltalk channels, that'd be cool. Thanks. -- Travis Griggs Objologist "I choose. Therefore, I Am"

Postgres
by Ramiro Diaz Trepat 29 Mar '07

29 Mar '07

Hello, I need to connect to a Postgres database. I've installed the PostgresV2, Glorp and Ramon's MagritteGlorp package. First of all, I wanted to test the Postgres package, so I changed the connection arguments in TestPGConnection to the server, userid and password used that I am using, and then executed the most basic method: testConnection, which coughed at me: "PGConnection has a defective state machine" Is there any particular thing I should reset or install to get the Postgres package to work? Thanks r.

Fastest way to mock up web UI?
by Andreas Raab 29 Mar '07

29 Mar '07

Folks - I have the need for mocking up a bit of a web UI as an administrative interface to some domain objects living inside Squeak. What is the easiest[*][**] framework to use for that purpose? I'm sure one of the options is Seaside but I'm not sure it is the only game in town, neither am I sure if it's the right thing for the task at hand. Since I remember that various people had used a number of frameworks I'm curious about alternatives and tradeoffs. Any opinions or recommendations? [*] easiest = least painful install, reasonably quickly to learn, fast intermediate results, open to future extensions (in case that UI needs to become "not-so-mockup" anymore ;-) [**] One strict requirement though: It must work under 3.8/Croquet. Thanks, - Andreas

.Net help or COM alternatives?
by Boingo 29 Mar '07

29 Mar '07

Hello all, With the help of some people on the list, I have made some progress with using COM automation with Squeak. I am still stuck with a few steps, so I asking the list again, to see if anyone can push me in the right direction. I am trying to access a particular COM object from Squeak. Most of the indicators I can find, say to use it through the .NetBridge. The site <http://wiki.squeak.org/squeak/3773> shows how to turn a COM object into a .Net assembly. I have done this and that part works fine. The documentation for the COM object I am trying to access can be found at <http://www.sagesoftware.com/education/webinar/MAS90ObjectInterface.pdf>. It has code in VBS in the documentation that works. I also have sample code in VB and C# that works against the original COM object. I have the .Net assembly working to a point. Once I get to a certain point in the code, I can get no further. The code is below. Hopefully someone can nudge me in the right direction, as I have tried to contact the author, with no success. Or, alternatively, if anyone knows a better way to access COM from Squeak, I am all ears. The code is below, with the part that fails commented. Thank you in advance to anyone who can help me out. ----------------------------------------------------------- companyCode := 'ABC'. username := 'sup'. password := 'sup'. oScript := nil. oSS := nil.

PackageInfo>>methods
by Norbert Hartl 28 Mar '07

28 Mar '07

Hi, I have a problem saving my project with Monticello. In PackageInfo>>methods ^ (self extensionMethods, self coreMethods) select: [:method | method isValid and: [method isLocalSelector] and: [method methodSymbol isDoIt not]] the call isLocalSelector doesn't succeed. There is no isLocalSelector in MethodReference. I use PackageInfo from squeak 3.9-final and Monticello from squeakmap (latest). I'm wondering that nobody has this problem. regards, Norbert

mac browser plugin tester with osx 10.3 needed
by John M McIntosh 28 Mar '07

28 Mar '07

Seems I need someone with os-x 10.3 to test the new mac browser plugin. We have in the plugin a 10.4 only api call, I've added a fallback to use a 10.3 call, but seems *all* the machines I've access to are running 10.4, so I can't test to confirm everything *does* work. So I'm looking for someone that still has 10.3.x on their macintosh and are willing to quickly try the new mac browser plugin to confirm that it works. -- ======================================================================== === John M.

[ANN][Squeak-dev Image] Version 95-2
by Damien Cassou 28 Mar '07

28 Mar '07

Squeak-dev image is an image made for squeak developers based on Squeak3.9-final-7067. If you use it, please tell me. You can download it here: http://damien.cassou.free.fr/squeak-dev/ Changes in this version: ------------------------------ - Changes the documentation a bit. - Updates the universe system (changes the distant server port from 8888 to 80 and fixes a crash). But the real changes have been made in the universe. Lots of packages have been added and updated. Starting from this version, you will be able to update your image using the Package Universe Browser (in the Open menu). Just update the list, choose to select all upgrades and then click on install. Prepared packages: -------------------------- There are a lot of packages prepared for you in this image. They are not loaded in the image, but they can be easily. - Open Package Universe Browser (world->open...->Package Universe Browser). - Click on "Update list from network" - Wait a few seconds - Choose your packages Future work: ---------------- - Wait for feedback. - Base squeak-dev image on Keith Hodges 3.9.1. - Think about a new way of versioning the image. This is because currently, the version is based on the Monticello repository version. However, the big updates/changes now happen in the universe directly and I don't have to touch the source code anymore. That's why this image is named '95-2' and not '96' or something else: the source code didn't change. Please tell me what is your experience with this version. Please tell me what you want for this image, this is for you. -- Damien Cassou
