Initial versions for OSWindow and Woden
by Ronie Salgado Aug. 20, 2014

Aug. 20, 2014

Hello There, I have been working in OSWindow, which is a cross platform API for dealing with native operating system windows. This API requires using a custom VM and the library SDL2. With this API, even the main Pharo window is handled almost completely in image side using NativeBoost. The only support required from the VM is a small periodical check in the heartbeat about the presence of events. This no more than 10 lines of code. This is currently working very well in my Linux machine, so I need to start testing this stuff. For Windows, soon I will be building the custom VM. My last built was very dirty and I want to do something more clean. For Mac OS X, I don't have one for testing. But Alex is going allow me to borrow one for some time. So be patience. As for Woden, it is a new 3D graphics engine that I started making. This one requires currently support of OSWindow and also shows some cool stuffs. As for prebuilt versions of the VM with OSWindow support along with preloaded images for both, OSWindow and Woden. And screenshots. Well, I am putting them here: http://ronie.cl/OSWindow/ Greetings, Ronie

[ANN] Ephestos - Using and Coding Blender from inside Pharo
by kilon alios Aug. 14, 2014

Aug. 14, 2014

Its far from production ready but I am too excited to keep to myself. I present to you Ephestos. Ephestos is a socket bridge that communicates with Blender the most popular and most powerful open source 3d application. http://www.blender.org/ The goal is to expose Blender coders to the power of Pharo and Pharo to the power of Blender. As you can imagine the potential is huge but I rather talk what Ephestos can do already. Even though Ephestos is in total less than 200 lines of code it can already communicate with blender and affect blender properties. Blender properties are basically instance variables for any kind of blender object, 3d object, material, textures etc So already you can affect a huge deal of blender . Unfortunately Blender operators seem to crash Blender , probably I am doing something stupid that I will fix. Blender operators are for performing blender actions so they are very important. I have made a simple video demo of it that can be watched here https://www.youtube.com/watch?v=8igk9DoY6PU&feature=youtu.be To use it you need first the Blender addon which can be found here https://github.com/kilon/pyEphestos The code should be inside a folder named "pyEphestos" and placed in Blender addons directory which is located for Macos in Application Support/Blender/VersionsOfBlender/scripts/addons and in Windows should be in App Data/Roaming/..... or you can place it inside the blender folder in similar sub directory You also need the Pharo code which can be found here http://www.smalltalkhub.com/#!/~kilon/Ephestos/ As I said it is far from production ready , but it works. The good news is that the socket communication is blazing fast, at least compared to what I expected. I was able to perform 1000 connections under a second. And each connection carries a 1024 bytes messages , thats a lot of code. Should be possible to pass thousands of lines of code under a second to Blender. My only worry is blender itself since it tends to be very crashy in the areas I am pushing. By the way Always press esc after you enable Ephestos in Blender to close the socket or else it wont free it and next time you wont be able to open the socket and you will have to restart your OS. And do not make an error with the string passed . I need to add an exception for it so it wont crash blender.

Re: [Pharo-dev] [Article] Elegant Pharo Code

Very nice, except all this could be done in Ruby, also elegantly. The Smalltalk advantage is the live image, and that's where the focus should be.

DFlow needs you
by Roberto Minelli Aug. 12, 2014

Aug. 12, 2014

Hi guys, As part of my research, I am conducting an experiment on how Pharo developers use the IDE and I really need you. My final goal, as we discussed at ESUG last year, is to improve the UI of our IDE to better fit our needs. To do so, I first need to collect interaction data from real developers. I would like to ask you if you and your team could install DFlow, my interaction profiler, and record your development sessions on a daily basis. The tool is not intrusive and requires minimal effort to be used. There is a simple UI that lets you start/pause/stop the recording. When you stop the session it automatically shares the data with me (through HTTP requests). If I manage to collect enough data and discover some insights I will share them in my ESUG talk! I am looking forward to hearing from you! Cheers, Roberto P.s. You can find installation instructions at the following link: http://goo.gl/ZKYNUI

[Remainder] Call for participation to the Second Visualization Contest with Roassal
by Alexandre Bergel Aug. 8, 2014

Aug. 8, 2014

Dear colleagues and friends, We are happy to announce the Second Visualization Contest with Roassal. What can I win? - 150 euros, sponsored by ObjectProfile - a Ã¼ber-cool ObjectProfile T-shirt and some wonderful stickers - maximum publicity of your work - a nice award certificate, delivered during ESUG How can I win? - you have to produce a visualization with Roassal. You can use the Pharo, VisualWorks, Amber or VAST version of Roassal. Here is an example of what we expect http://bit.ly/sunburstDemo http://bit.ly/GraphET https://vimeo.com/96091089 about smartbrowser https://vimeo.com/94724841 about GraphBuilder http://www.youtube.com/watch?v=uOmox7NgRAg&feature=youtu.be on AspectMaps, by Johan Fabry, the winner of the contest last year - making a video is mandatory. The video will weight the most in our decision. The video could be of any length and has to include your name and say that is was made (partly or completely) with Roassal. No need to talk, just show off! - making your code available and easy to install will help you get more points How can I submit? - send the links of your video and other material (if needed) to info(a)objectprofile.com Every email you will send to this email will be acknowledged. If you do not receive a 'Ok' from us, it means we haven't read it, in that case send your email again after a few days. - the deadline for submitting is August 11, 2014 Mini FAQ? - Is the object-profile team allowed to participate? No - I know nothing about Roassal, how can I start? Roassal comes with a large set of examples. On Pharo, just use the example browser available from the world menu. The book http://www.deepintopharo.com also contains chapter on Roassal 1 and Mondrian. You are also very welcome to ask question to the Pharo or Moose mailing lists about Roassal. Or simply send email to info(a)objectprofile.com . We will help you. - Iâve heard about Roassal2, Roassal3d, Roassal1. I feel lost in all these keywords! Wellâ¦ Roassal1 is available on VisualWorks and VAST. Roassal2 works on Pharo and Amber. Roassal2 is a major revamp of Roassal1. The documentation on Roassal1 may be easily adapted to Roassal2. - Should my visualization or code be open source? No need for this, whatever license is fine. However your video has to be public. - How can I get more information? Just comment on the facebook https://www.facebook.com/ObjectProfile or using Twitter @ObjectProfile or send email to info(a)objectprofile.com or the pharo or moose mailing list - What I submit two different videos? Yes, no problem with that. As many as you are productive. - Who won last year? Johan Fabry with AspectMaps made a nice video about visualizing aspects. - How will judge the videos? both the esug community and the object profile team. The Esug community will have 30% of the final grade, object profile the remaining 70% Cheers, The profilers

Deprecator
by Camille Teruel Aug. 7, 2014

Aug. 7, 2014

Hello Pharo users, I'm pleased to announce the release of Deprecator. It's a prototype of a small tool that permits you to deprecate method by annotating them with a <deprecated: ...> pragma. This pragma takes a rewrite expression as argument that specifies how to rewrite the message send to the deprecated method. If such a deprecated method is executed, a warning is thrown and a debugger opens. This debugger has a little 'Rewrite' button that permits to rewrite the sending method according to the rewrite expression and then resume the execution with the new rewritten sending method :) The implementation is a proof-of-concept and is a bit hacky here and there, but it works. Example: You have a class C with a method that you deprecate. Its rewrite expression tells that if it's executed as the result of a message send of the form: <receiver> deprecatedMethodArg1: <arg1> arg2: <arg2>, this message send should be rewritten to: <receiver> replacementMethodArg1: <arg2> arg2: <arg1>. Note you can change the order of arguments or even the receiver. C>>deprecatedMethodArg1: o1 arg2: o2 <deprecated: '`@receiver replacementMethodArg1: `@arg2 arg2: `@arg1'> ^ #deprecated C>>replacementMethodArg1: o1 arg2: o2 ^ #replacement C>>senderMethod ^ self deprecatedMethodArg1: 1 + 1 arg2: 2 + 2. Then if you execute C new senderMethod, and then click on the "Rewrite" button of the debugger, then sending method is rewritten to: C>>senderMethod ^ self replacementMethodArg1: 2 + 2 arg2: 1 + 1. and the result is #replacement. The repo is on sSmalltalkHub: MCHttpRepository location: 'http://smalltalkhub.com/mc/CamilleTeruel/Deprecator/main' user: '' password: '' I hope for comments, feature suggestions, code reviews, contributors, etc :) BTW, if you have a better name for this project let me know! For example, I thought about Ammonite because it's an extinct animal (analogy with deprecated) and it fits the sea naming theme. Cheers, Camille
