help with tests
by Usman Bhatti March 30, 2013

March 30, 2013

I need some help with tests. I have a set of classes for UI testing. There's an abstract super class that defines abstract methods for testing (title, classtotest, model etc). Then each subclass defines its own tests. It works so far until I have each subclass defining each its own specific tests. Now, I need to add a test that is common to all subclasses so a candidate to be placed in the super class, but my superclass only defines a framework for tests, hence this test wont have the data to execute the test and this would not execute correctly in my abstract super class. My questions: 1) Is there anyway to say not to execute the tests in the abstract class. 2) inherit tests from an abstract super class? Apparently, #shouldInheritSelectors does not work for abstract classes or I am not understanding some design rules. tx, usman

Redrawing browser with new font settings
by Norbert Hartl March 28, 2013

March 28, 2013

If a font in pharo is changed most windows stay with the old settings and only new ones take the new settings. The Settings window adjusts immediately if all fonts are set to the default font. So, is there a way in a deliberate way to let a window redraw itself with adjusting to new font settings? Norbert

NeoJSON Mappings
by Esteban A. Maringolo March 26, 2013

March 26, 2013

Hi, I'm happily mapping my objects to JSON. But in order to reduce the payload I'm looking for a way to map my objects differently depending on whether it is the root object of the mapping or not. Let's say I have two classes with the following instvars between parenthesis: * ClassA(id, name) * ClassB(id, classA) I'm using #neoJsonMapping: to define the mappings and (NeoJsonWriter toString: classB) to get the JSON string. If in the Class B mappings I reference classA (by instVar or accessor) I get the whole ClassA instance serialized as JSON. Which is not what I want. I'd like to have only the id of classA. I know I can define a custom mapping using for:customDo: , but I'd like to know if there is another way to do that. And this relates to another point, that is how to define a schema for a whole hierarchy of objects. All my objects are descendant of a common superclass. There is no way I can do the following on different levels: super neoJsonMapping: mapper. mapper for: self do: [:mapping | mapping mapInstVars: #(foo) ] Because on every call it overwrites the mapping for the schema of the current call, ending up mapping only the instVar 'foo'. I can work my way around this by writing more, refactoring and so on. But I would like to know if Sven or somebody else who uses NeoJSON have some practice patterns that would like to share with the rest of us, mere mortals. Best regards! Esteban. -- View this message in context: http://forum.world.st/NeoJSON-Mappings-tp4677077.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

If you can make it into a 30 second teaser, or even a 6:40/20slide pecha kucha, we could even publish them already. Doru: will there be a default presentation machine with screenflow?

A multi-cam setup would be great. Being able to switch from question to answer view helps. That would require one camera to be in front/to the side, facing the public. I don't know how practical that is with the available room (and camera zoom). Stephan

Video registration of Pharo/Moose days
by Stephan Eggermont March 25, 2013

March 25, 2013

Hi, Diego will take my video camera with him, making it possible to record the presentations, so we can put them online. He does not want to spend three days only recording talks though. He would like some volunteers to record one (or more) sessions each. Any takers? The idea is to just keep the camera zoomed in on the speaker. Slides can be separate. Could a tripod be provided locally? That would be much more comfortable and better for the quality of the recordings. Will there be enough light on the presenter to make it worthwhile, or will the room be dark for the beamer? If the machine with the presentation has ScreenFlow, it would be possible to merge the video stream with the presentation and get really slick results. I would be willing to do the editing. Cheers, Stephan

Even though we can, I'd prefer it if those being there would take a look at the program and speak up on which session they would like to record themselves. That way you can make sure you can have your full attention to the sessions you need to see (because when you are recording, you tend to focus on other things than the story being told). Camillo wrote: >I think I will have to use my own machine for the commandline presentation >(custom terminal font and co..) and I don't have screenflow. Ah, it works on my machine :) >Do you think it will work if I do a screen recording using Quicktime? Yes, Screenflow can import quicktime recordings. Just make sure to use a sensible format, as both enormous files and bad image quality are annoying. Synchronisation is no problem. ScreenFlow just allows after-the-fact highlighting/zooming/panning etc. Cheers, Stephan

[ANN] Phratch: Scratch on Pharo2.0
by jannik.laval March 25, 2013

March 25, 2013

Hi Pharoers, I am porting Scratch and BYOB on Pharo 2.0. The name of the project is Phratch. To begin, I took Scat (a port of Scratch on Pharo1.3) and modify it to make it work on Pharo 2.0. For that I integrated FileSystem. Then, I took BYOB and port it in the project. I have some bugs, but the main features are working. The main issue is that it is slow. I will investigate that too. The goal for me is to use it for teaching software engineering and robotics. I hope to use Phratch and Pharo 2.0 to create new features. The project is on SmalltalkHub, and a google code page is available, mainly for reporting issues: https://code.google.com/p/phratch/ To download Phratch, just run this code: Gofer it url: 'http://smalltalkhub.com/mc/JLaval/Phratch/main'; package: 'ConfigurationOfPhratch'; load. (Smalltalk at: #ConfigurationOfPhratch) loadBleedingEdge. Cheers, Jannik

Interesting ! I will see that. Who is active on this project ? Should it work on Pharo2.0 ? I am interesting if we can merge efforts.
