[ANN] RFB for pharo 2.0
by Norbert Hartl May 7, 2013

May 7, 2013

I moved the sources for RFB from Lukas' site to smalltalkhub http://smalltalkhub.com/#!/~PharoExtras/RFB/ I also copied the ConfigurationOfRFB from MetacelloRepository to smalltalkhub. There I applied the changes for RFB to be runnable in pharo 2.0. To load it use Gofer it smalltalkhubUser: 'PharoExtras' project: 'RFB'; configuration; load. (Smalltalk at: #ConfigurationOfRFB) load Norbert

I think this could be a problem with SmalltalkHub in general, but http://smalltalkhub.com/#!/~zeroflag/BabyMock does not load in InternetExplorer -- it just hangs with 'Loading...' in upper right -- but it does work fine in Chrome, Firefox, and Opera browsers.

Kinematic Templates implemented in Pharo
by Carla F. Griggio May 6, 2013

May 6, 2013

Hello! Some months ago GermÃ¡n Leiva and I did a project for the course "Introduction to Human Computer Interaction" at UniversitÃ© Paris-Sud where we had to implement an interaction technique, and we chose to implement Kinematic Templates in Pharo (or well, at least a little prototype). Maybe it's useful for somebody, so here's some info :) The Kinematic Templates interaction technique suggests adjusting the user's mouse input to it tends to match a drawing template. That allows the user to draw in free-hand mode and obtain a "beautified" version of it's hand drawing. You can watch the original Kinematic Templates demo<http://www.youtube.com/watch?v=5lseh9ghhJ4>and read the paper <http://dl.acm.org/citation.cfm?id=1449725>. This is a video of our implementation in Pharo<http://www.youtube.com/watch?v=p2AmU4nqnLw>. And here you have the report<https://docs.google.com/document/d/18gXYdhhPQlXUNGCqbEEBRgb2NRyKLgYcIeURoAQ…>that we handed in for our evaluation too, which can be useful as documentation. In the report you can find links to videos that show the progress of the project. BTW, it only works on MacOS, sorry for that :$ It's because we only dealt with the FFI calls to that OS in order to manipulate the mouse position. You can get the code from: http://ss3.gemstone.com/ss/KinematicTemplates To open the window for drawing with Kinematic Templates evaluate in a workspace: KinematicWindow openExample Cheers! Carla

Oops, good point! As we handed in the image for our project I didn't realize that. I'll fix it later! Thanks Sent from my Windows Phone ------------------------------ From: Guillermo Polito Sent: 5/6/2013 10:15 AM To: A friendly place where any question about pharo is welcome Cc: GermÃ¡n Leiva Subject: Re: [Pharo-users] Kinematic Templates implemented in Pharo Hi Lider! The video is cooool :). Congratulations! Some feedback :). I could not use it :$. - I needed to download FFI first (and I did it and it loaded :), - and then it needed a lot of image files I do not have in my disk, so it explodes while loading the icons, and the background images of the templates... Maybe then can be packaged somewhere... Saludos! On Mon, May 6, 2013 at 3:00 AM, Carla F.

Pharo 2.0 debugger strange behavior
by xavier MESSNER May 5, 2013

May 5, 2013

Hi, Since Pharo 2.0 on Linux (20599) i have strange behavior when i'm trying to debug a method step by step. Step to reproduce : 1. Create a new Package 'TEST' 2. Create a new subclass 'Test' 3. Create a method 'Validation' Validation |col| col := OrderedCollection new. col add: '1'. col add: '2'. col add: '3'. 4. Add a breakpoint on this method. 5. Open a workspace 6. Write on it : Test new validation. 7. Alt-d to do it A debugger window appear. I choose 'debug' and then choose my method. I can see my code in the window. Normally when you click on 'Over' you can go step by step through your instructions. In 1.4 next instruction was highlighted, but not in 2.0 and 3.0. So you can't see what is done. This feature in 1.4 save me a lot of time fighting bugs and learn smalltalk. Is this a bug ? someone has already seen that ? Regards, Xavier.

Spec One-to-many
by DeNigris Sean May 5, 2013

May 5, 2013

I'm having difficulty expressing a one-to-many relationship in a Spec UI (in Pharo 2.0). I want to have a dialog where the user can enter a business expense, which will be assigned to a particular account (see screenshot). I tried: - using a DropListModel. This disrupted the flow because it seems it can't be typed into, so the user has to mouse through to find the correct account - using a TextInputFieldModel with entry completion. It seems that this suffers the same fate as above. In its current form, it's almost unusable. Pressing the down arrow to select an item from the completion menu makes the menu disappear, tab makes the widget lose focus, and I have complete on enter disabled, so again one must mouse click on the menu What would be the best way to express this without forcing the user to take their hands off the keyboard? Thanks! Sean

[ANN] BabyMock 1.0
by Attila Magyar May 3, 2013

May 3, 2013

Hi, I'm happy to announce the 1.0 version of BabyMock. BabyMock is a visual mock object library for Pharo Smalltalk, that supports test-driven development. Like other mock object libraries, BabyMock helps you design and test the interactions between the objects in your programs. BabyMock makes these interactions visible, which may help you identify test smells easier. [..] You can read more about BabyMock at the following address: http://smalltalkhub.com/#!/~zeroflag/BabyMock <http://smalltalkhub.com/#!/~zeroflag/BabyMock> regards Attila -- View this message in context: http://forum.world.st/ANN-BabyMock-1-0-tp4685027.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Serializing an error (Fuel)
by Bernat Romagosa April 29, 2013

April 29, 2013

Hi list, Until recently, we've been dealing with all errors in our Iliad application by having the Iliad error handler serialize them and send us an email referring to the file. This way, debugging was as easy as: *GRPlatform current openDebuggerOn: (FLMaterializer materializeFromFileNamed: 'errorReports/1366980822.obj'). * But recently this has stopped working, and I've just found out I can't even serialize simple errors. Something like: *[ 3 / 0 ] on: Error do: [ :error | FLSerializer serialize: error toFileNamed: 'error.obj' ] * brings out a debugger saying I need FuelMetalevel to fully serialize methods (which is installed, by the way). The error reads: *FLNotInstalledMethod: Serialization error. DoIt can not be serialized as global because it is not installed. You need FuelMetalevel to fully serialize methods. See the documentation.* I'm not sure whether one thing is related to the other... any ideas? -- Bernat Romagosa.
