Esteban said <<< Hi, It does not really matters where you put the test. What matters is to have the tools that show them properly, and we are going in that direction. We already have ways to "jump to tests" in Nautilus, and we will continue improving that to show them together (for example). But I do not think the tests need to be *in* the class definition to have same level of interoperation. Esteban >>> I agree. The actual architecture doesn't matter. The critical factor is making it as easy as possible to write/navigate tests. I didn't know about the Nautilus features. I shall have to go and experiment. Also, thinking about Doru's point. I wonder if we could write tests/examples in the comments section of code. It might be an interesting addition

I am sorry for the off-topic. A friend of mine was stolen in Sofia and now she is completely out of money going to St. Petersburg in a few days. Anyone there who can help her a little bit would be really appreciated. Cheers, HernÃ¡n

Doru said: <<< I stumbled across this idea when Markus Gaelli chose it as a PhD topic about ten years ago (man, I'm old). The main idea was not to provide tests, but examples that happened to have assertions. The goal was twofold: (1) provide live documentation with real objects, (2) provide another way of composing tests. The project did not really come to fruition, but I still think this is highly interesting topic. Part of the ideas were later implemented in Phexample (http://www.smalltalkhub.com/#!/~Phexample/Phexample/) and JExample (http://scg.unibe.ch/research/jexample) >>> That's really interesting. I had never heard of Phexample - so many interesting projects, so little time! - I like the approach of building on tests. Do you know if this will work in Pharo 3? Also, I may have misunderstood what Pyret was doing. Perhaps it is more about examples.

Here is a demo of the i18n support in QCMagritte. It supports live editing of the languages and strings used in your application. youtu.be/cTut44Xs3_U Stephan

In the multi language demo of QCMagritte, a magritte visitor is used that changes all label:, checkboxLabel:, comment: and group: sends in descriptions to automatically use a multilanguagestring. The parameter is used as the key. All unique keys are collected. The default translation is the key. That is used for missing translations. Languages can be added on the fly. The demo has a simple UI to directly add and change translations. The whole translation table can be written to csv, and read back. This is not shown in the video Stephan Verstuurd vanaf mijn iPhone

Finding references to traits
by btc＠openinworld.com Nov. 16, 2013

Nov. 16, 2013

If I come in cold to a system and see some class using trait, and then I want to find all classes that use that trait. I have tried a few ways but failed to work it out. The most obvious action "Extended search > references of it" doesn't show them, and neither does any other action I try. How is this done? cheers -ben

Hi! Today StÃ©phane mentioned project Periscope (Universal Navigation Sidebar for Nautilus). Does anyone use it or maintain it? It looks like it does not work.

[Spec] How to adding my scroll bar
by Gisela Decuzzi Nov. 16, 2013

Nov. 16, 2013

Hello, I have a component that basically contains lot of widgets and I want to add a scroll bar to it. But I didn't find a way to do this. I'm using Pharo 2.0 (I know 3.0 is better but I needed something stable). My spec is a ColumnLayout with lot of rows. Maybe I should use another? Can someone point me where to look at?

NBOpenGL on Pharo 3.0
by Richard Wettel Nov. 15, 2013

Nov. 15, 2013

Hi CodeCity, the project I am working on is based on NBOpenGL. I'd like to start working on it using Pharo 3, but it seems that NBOpenGL does not work yet with Pharo 3.0. I downloaded from jenkins the latest image with Pharo 3 and tried to execute the following code on Windows 7, 64 bits: GLTTRenderingDemo new openInWorld. but I get a 'No suitable implementation found for initializing OpenGL context for your platform'. It seems that NBGLContextDriver does not have a subclass for Windows 64bits. Did I omit something? Cheers Ricky

Arduino package extra files
by Bernat Romagosa Nov. 15, 2013

Nov. 15, 2013

Hi list, After successfully installing the Arduino package, I noticed this Getting Started text: *After installing the Arduino packages by evaluating...* * * * ConfigurationOfArduino load.* * * *...you'll need a couple extra support files in order to be able to upload programs to your Arduino board. You can download them from here:* * * * http://www.mediafire.com/?1rep41uygl4rpf1* * * *Extract the contents of that file in the same directory where you have your Pharo image.* But the mediafire link is broken. Where can I get the extra support files? Thanks! Bernat. -- Bernat Romagosa.
