by Michael Haupt

* apologies for multiple copies * The submission deadline for the International Workshop on Smalltalk Technologies (IWST) 2010 has been extended to June 18. Please find the details below. Call for Papers International Workshop on Smalltalk Technologies (IWST) 2010 co-located with European Smalltalk User Group Conference (ESUG) Barcelona, Spain, September 11-17, 2010 ** Description The goal of the IWST workshop series is to create and foster a forum around advances or experience in Smalltalk. We welcome contributions on all aspects, theoretical as well as practical, of Smalltalk-related topics. There are two possible kinds of submissions, which must be in ACM SIGPLAN style: * Research papers (up to 10 pages). Submissions in this category will be rigorously reviewed, and accepted papers will be published in the ACM Digital Library (ACM SIGPLAN has approved, the final ACM approval is pending). * Demonstration papers (up to 4 pages). Submissions in this category will not be published in the ACM Digital Library, but will be available for download from the workshop web page. ** Submission and Reviewing Process The EasyChair submission web site is at http://www.easychair.org/conferences/?conf=iwst10. Authors will be given the opportunity to comment on reviewers' work by providing feedback on the reviews. For this purpose, a questionnaire will be sent to authors. Their answers will be evaluated anonymously, and feedback will be handed on to reviewers. ** Important Dates Submission: June 18, 2010 (Samoa time) Feedback: July 16, 2010 ESUG Early Registration Deadline: July 9, 2010 Authors will be able to register for the early rate if their registration depends on IWST notification.

Re: [Pharo-users] Using FFI to call a MacOs System function

by David Wilson

Hi Mariano Thanks for the tips, you got me on the right track. Some trial and lots of error got me to a solution. In order to use MacOs system calls you have to: 1) identify the function you want to use e.g. KLGetKeyboardLayoutCount 2) find out what header file this is defined in. here it's "Keyboards.h" in the Framework "Carbon/Carbon.h" So far it's easy from the Apple documentation 3) find out which Bundle this is in. I used Finder to find out where Keyboards.h is used, it's used in HIToolbox.framework 4) find the actual compiled framework, on my system it's at: /System/Library/Frameworks/Carbon.framework/Versions/A/Frameworks/ HIToolbox.framework/Versions/A/HIToolbox 5) I placed a copy of this file in the Pharo bundle at: Pharo-1.0.app/Contents/Resources/HIToolbox An the call looks like: apiKLGetKeyboardLayoutCount < cdecl: ulong 'KLGetKeyboardLayoutCount' (void) module: 'HIToolbox'> ^ self externalCallFailed. I tried a link to the bundle, that didn't work. Probably the correct way to do this is to change Pharos RES path (in Pharo.sh) to include the a pointer to HIToolbox executable. I may try that if I go further with this than a prototype.

I get an error "'Unable to find function address'" which seems to say the OS-module "keyboards" can't be found. Exactly. That's the problem. I can't figure out what the address should be. The function is defined here: http://developer.apple.com/legacy/mac/ library/documentation/Carbon/Reference/KeyboardLayoutServices/ Reference/reference.html (yes, it's deprecated, I have a very old mac runnning 10.4). But you see the library in your computer, isn't it ? I mean, it is there, but FFI doesn't find it ? I'm not sure if I'm using FFI correctly, do I have to somehow include the external library in the Pharo VM? No, you shouldn't need to do that. However, you can try to put them there just to see if that's the problem. I think that at some point (depends on an order) the library is searched in the same place where you are calling from. So, yes, do a test, but just a test. It should work without doing that. How did you install FFI ? Which Pharo VM and image versions are you using ? Can anyone help? I would like too, but I don't have such library. I developed a wrapper for a Clibrary called OpenDBX using FFI. In our website, some people experimented similar problems. Please take a look to the title "Problems with Mac OS:" of the following link: http://www.squeakdbx.org/Compiling%20and%20installing%20OpenDBX I also cc'ed people that can help you. Cheers Mariano I'm looked for FFI examples, but don't find anything helpful.

Help (perfect for newcomers) migrating a technical FAQ

by Mariano Martinez Peck

Hi folks. I had a good idea and and it perfect for someone that wants to help and don't know how. It is not the most entertained task, but I promise you will learn a lot. Mostly, if you are newcomer. The idea is basically to migrate the FAQ that is here: http://scg.unibe.ch/wiki/faq/pharofaq to a new section in the collaborative Pharo book: http://book.pharo-project.org/ So....any takers ? Let us know so that we generate a new user in the Book The idea is also to check whether what is says is still correct for pharo or if it needs an update. Or even how to improve it (from the view of a newcomer). Thanks Mariano

Help testing Pharo 1.1 in big screens!

by Mariano Martinez Peck

Hi folks. I re-try (yes, yes, I re-insist hahaha) to have a background picture for the PharoDev 1.1. The last time I tried, we had a problem with the picture because in big screens instead of making it bigger, it put it several times, or it cut it. Now, thanks to Gary, it should work well. So, if you are a lucky guy an have a big screen, can you please take the latests PharoCore 1.1 image, for example this: https://gforge.inria.fr/frs/download.php/26995/PharoCore-1.1-11357-UNSTABLE… How to test it ? - Download this in the same directory where the .image is: https://gforge.inria.fr/frs/download.php/26996/pharoBackground.png Then evaluate: World backgroundMorph: ((UITheme builder newAlphaImage: (ImageReadWriter formFromFileNamed: 'pharoBackground.png') help: nil) autoSize: false; layout: #scaled; lock) What to test ? - You should stretch the pharo image, make it very big, and the background picture should stretch also together with the image. - If you notice a performance decrease with it (I don't think so) - If you like it or not. - If the resolution is good enough in big screens Thanks!
