[Issue tracker] Help needed for reviews
by Marcus Denker Jan. 3, 2014

Jan. 3, 2014

Hello, We have some issues ready that nevertheless need to be reviewed by humans: https://pharo.fogbugz.com/f/filters/45/Review We know that they do not make tests fail and even pass some code critic tests. But else? -> do they fix the problem? -> Is this a change that we can risk to do after code freeze? -> is the change good? Marcus

Weird Athens Artifact
by J.F. Rick Jan. 3, 2014

Jan. 3, 2014

I've been converting DigiTile over to Athens with general success but I have found an odd rendering bug. In this scenario, I am moving the brown square around with a hand. As I am using AthensWrapMorph, I have made it so that the brown square is a submorph of the application (an AthensWrapMorph) and not in the hand. The brown square is actually twice the extent that it appears (i.e., it has a 50 pixel transparent border). This has to be done to allow rotation handles to be added. Anyway, when it moves so that its top would go beyond the top of the application, some crazy rendering effect happens, as illustrated in the included screenshots. This same behavior happens when moving the square to the left side of the screen. It does not happen on either the right or the bottom of the screen. It seems like Athens does not like for submorphs of AthensWrapMorph to extend to the left or above their parent. This seems like a problem and something that can easily happen as somebody moves some morph to be partially offscreen.

Compiling chapter of "Pharo for the Enterprise"
by Natalia Tymchuk Jan. 3, 2014

Jan. 3, 2014

Hello. Merry Christmas. I write a chapter to "Pharo for the Enterprise". And I want to compile it, but when I executing ./compile.sh DSL/DSL.pier, like it is writen here: https://github.com/SquareBracketAssociates/PharoForTheEnterprise-english/bl… , I get No yet implemented. I just start this chapter and it isn't ready to be added to the PFTE.tex. Should I add it to PFTE.tex or there are another way? What can you recomend me? Thanks. Best regards, Natalia

Thank you for Pharo

Thank you for Pharo â¦. I am following the development of Pharo since its fork from Squeak, and i am really impressed what you crazy guys all have archived the last years. It all evolved to really nice language, a fantastic nice looking live programming environment, cool packages and a growing ecosystems. I have so much fun using Pharo. Thank you. 2011 i gave me a push to learn Pharo and last year i decided to do a small research prototype with it. The goal is a tool to analyze and visualize application landscapes. I have implemented a small repository model for the different architecture levels, some data analytic rules on top the model, and some model visualizations. For visualization i use Roassal/Mondrian. For Data-In/-Export i use simply NeoCSV. Next year i plan to add more data analytic rules, to add model transformation operations to "simulate" landscape transformations (projects), and to use 3D visualizations with Roassal3D (City Metaphor). If all works fine, we see what 2015 brings ... Pharo is really a productivity boost for me. If you are able to play around with the objects in an interactive environment life is getting so much easier. My wishes for Pharo: - Some kind of "Pharo Capability Map". It is really hard to understand for a newbie what Pharo is all supporting, what is planed for the future, what the library names are, .... - Stable Pharo 3.0 - Roassal3D (Roassal is so coooool, one of the killer frameworks for Pharo). - More User Interface programming examples - 64 Bit VM and MultiCore Support Thank you guys, and best wishes for 2014 Volkert

Re: [Pharo-dev] Don't make me think (the one thing you shouldn't ignore about user interfaces)

Sebastian wrote >Cheap idea for us: Good idea for a bit later, and for the new parts. We already have a number of well-known problems for new users. If we donât eliminate them first, weâre not going to find much new issues. They will be hidden behind: - no discoverable way of creating classes & methods; - buttons in the system browser without a visible relationship to the pane they operate on; - context menus that donât operate on the selected item but on a whole group; - menu size - modal editing - keyboard navigation of the ui There are quite some Pharoâers teaching introductions to smalltalk. I think they are aware of these issues. A few of them are on my slides, at least. And a few I always have to explain. Stephan

Don't make me think (the one thing you shouldn't ignore about user interfaces)

Guys is no mystery that we have some issues with UI. It's not so bad either, we have many things that are light years ahead of other but we consistently miss some really basic stuff from the Human-Computer-Interactcion point of view. The community is biased towards engineering and unbalanced regarding to design so this is no surprise (why this happens is another interesting conversation). UI is not that hard when you know what to pay attention to but we need first to decide if we care about usability and the developer experience at all. This fantastic talk from Steve Krug exposes what's the least you can do for the usability of any software. http://blip.tv/business-of-software/steve-krug-on-the-least-you-can-do-abou… sebastian o/

guiding code changes with gtinspector
by Tudor Girba Jan. 3, 2014

Jan. 3, 2014

Hi, I think the inspector should become more prominent in the life of a Pharo developer. For example, the Inspector is perhaps the last tool you might see as useful for code manipulation, but if you see code as objects, it makes perfect sense to have some support in the inspector. To show how it can be different, I described two recent scenarios in which the GTInspector was essentially the only tool readily available to support editing of a custom set of methods: http://www.humane-assessment.com/blog/guiding-custom-changes-with-gtinspect… I would be happy to hear any feedback.
