Composing morphs
by Norbert Hartl Sept. 19, 2013

Sept. 19, 2013

I'm playing with morphs but having trouble getting it achieved. I have a set of geo coordinates that form a polygon. Over the polygon I want to lay a grid. The polygon I do with lineMorph ^ lineMorph ifNil: [ lineMorph := (LineMorph vertices: self coordinates color: Color red borderWidth: 1 borderColor: Color black) ] The grid I do with activeGridOn: aMorph | min max stepHorizontal stepVertical | min := self coordinates min. max := self coordinates max. stepHorizontal := (max x - min x) / 10. stepVertical := (max y - min y) / 10. min y to: max y by: stepVertical do: [ :y| min x to: max x by: (stepHorizontal) do: [ :x | | r | r := Rectangle origin: x@y extent: stepHorizontal@stepVertical. Transcript show: 'drawing rectangle ', r asString; cr. aMorph addMorph: (BorderedMorph new position: (r topLeft); extent: (r width@r height); color: Color red; borderWidth: 1; borderColor: Color black) ] ] But I cannot see the rectangles because they are too small. It seems the coordinate systems of the line morph and the added morphs are different. Is there a kind of transform need so that the line morph and an added morph can have the same sized coordinate values? Norbert

Point3D?
by Udo Schneider Sept. 18, 2013

Sept. 18, 2013

All, I'm currently implementing a wrapper for the LeapMotion Controller. Most of the values are Points in 3D space. So I'm searching for "the" standard package providing something like Point3D. Or did I miss the correct class in the base image? Thanks, Udo

[ANN] "OS" and "OS-Windows" project on STHub
by Torsten Bergmann Sept. 18, 2013

Sept. 18, 2013

Hi, with NativeBoost (NB) it is now possible to access not only external libraries but also the underlying operating system platform. Some examples are already included in the "NativeBoost-Win32", "NativeBoost-Unix" and "NativeBoost-Mac" categories within the NB project. But providing more and more examples and native API wrappers for the various platforms directly within the NativeBoost project itself would only bloat this project. NB should care about being a good external interface - nothing more. To keep NativeBoost clean with the basic functionality for a good foreign function interface Igor suggested to move specific API wrappers for the various operating systems into own project. To avoid duplicate effort in providing such wrappers it would IMHO make sense to host them in a central place. Therefore I created the "OS" Team on SmalltalkHub with a first project called "OS-Windows" allowing you to access Win32/Win64 functionality easily from within Pharo. It contains code, tests, many examples and documentation as a first contribution. With this initial project for Windows you can now work with the console, Shell, the internet explorer, GDI, windows processes, Control panel applets, ... I refer to the written documentation and many examples given at: http://smalltalkhub.com/#!/~OS/OS-Windows Provided code for Windows is stable and usable, if you have something to share to make it even more complete then you can easily contribute (how is described in the docu). Code is for Pharo 3.0 - you can load it easily from the config browser in a recent image. Try the examples given in the docu on the project page, look at the tests to get comfortable with it. Important: ========== Note that this idea is NOT LIMITED TO WINDOWS - it would be good if we could see pair projects like a "/~OS/OS-Mac", or "/~OS/OS-Linux" and others under the same umbrella so it follows a common pattern and is easier to access for people who require it. If someone asks if Pharo is platform independent I will answer: YES. If he asks if it is also playing nicely with the underlying platform to use platform dependent functionality I would also like to answer YES. If he wants to do some Mac stuff I would like to tell him: "just load "OS-Mac" from the config browser and start. Same for Linux, Windows, Android, YouNameIt, ... I can only provide a start for the basic framework with the hope that others will contribute as well and getting it into good shape as yet another good step for the possibilities in the Pharo universe. Side note: ========== You can read the docu online at the SmalltalkHub project page (http://smalltalkhub.com/#!/~OS/OS-Windows) - but also as a class comment on the ConfigurationOfOSWindows. If you have the "Pharo Online Help" loaded you can also view it there. Keep on talking small T.

PBE2?
by Yuriy Tymchuk Sept. 18, 2013

Sept. 18, 2013

Hi everyone, as far as I understand PBE2 is actually deep into pharo. Maybe we should update PBE because when someone new starts to work with pharo I usually suggest him to read PBE. Pharo 3 will have a lot of new cool features, and people have to work with 1.1. What do you think? Cheers! Uko

News from Mars
by Carla F. Griggio Sept. 17, 2013

Hey! I wanted to let you know that I've been updating my blog on Mars with the latest news, I've just posted some videos showing how different kinds of layouts and widgets are working together on both Cocoa and GTK. The blog: http://marsonpharo.wordpress.com/. For the ones that are interested in some implementation challenges that I had while building layouts that could work for both Cocoa and GTK, I recommend reading this post: http://marsonpharo.wordpress.com/2013/09/13/the-challenges-behind-building-… Cheers!

Re: [Pharo-users] [Pharo-dev] Seaside Continuous Integration on ci.inria.fr

Thanks a lot for the update :) On 2013-09-16, at 06:20, Philippe Marschall <kustos(a)gmx.net> wrote: > Please try to keep the build green, otherwise we'll get spammed with emails. I like this ;) > Currently we keep all the build (5GB already). Do we really need this? We live in 2013, 5GB is the data of single movie file I stream ;), so unless the CI guys start to complain, there is no problem in consuming that much space. Would it be possible to use the numeric versions in the CI build? Maybe it is just me, but for seaside I cared more about the numeric version, what do you think? Currently it is #stable => 3.0.X #development => 3.1.X

FileTree Monticello Repository
by Esteban A. Maringolo Sept. 14, 2013

Sept. 14, 2013

Is anybody using FileTree repositories? If so, I'd like to know the pros and cons of using it. I want to use to version everything with git, but I don't know how it keeps git (it is, FileTree files) in sync with MC versions. Regards! Esteban A. Maringolo
