Athens and ellipse drawing
by Juraj Kubelka June 30, 2014

June 30, 2014

Hi Igor, hi all! I am not sure how to properly draw ellipse. Right now I draw a path like this: The path is created that way: -=-=-=-=- computePath path := self athensCanvas createPath: [ :builder | builder absolute; moveTo: 0 @ 0.5; ccwArcTo: 0.5 @ 0.0 angle: 90 degreesToRadians; ccwArcTo: 0.0 @ -0.5 angle: 90 degreesToRadians; ccwArcTo: -0.5 @ 0.0 angle: 90 degreesToRadians; ccwArcTo: 0 @ 0.5 angle: 90 degreesToRadians ] -=-=-=-=- And draw it like this: -=-=-=-=- drawOn: athensCanvas athensCanvas pathTransform restoreAfter: [ athensCanvas pathTransform scaleBy: rectangle extent asFloatPoint athensCanvas setPaint: color; drawShape: self path. (athensCanvas setStrokePaint: strokePaint) width: (self strokeWidth / self scale) asFloat. athensCanvas drawShape: self path ] -=-=-=-=- But with a different shapes, the border does not have same width all around the ellipse. See the image: Is there better way to draw it? Thank you, Jura

Curl markup with Pillar
by Robert Shiplett June 3, 2014

June 3, 2014

re: Curl markup, as in web markup using declarative style in Curl PL from MIT, not cURL ( see www.curlap.com) My Japanese web pages are now generated using nunjucks + node.js but in the hope of using pharo 3 + Seaside on small virtual server, I thought I would see what it takes to add Curl markup to the Pilar repertoire. But the Pharo 3 RC image is giving a walkback over the configuration for Pillar, so I may not get to this this morning. mrkup, mrkdwn PS did any one see the role of an MIT OCaml / emacs guy in the Android visual app gen project from MIT ? PPS Curl Android/iOS app gen project is called "caede" as in "maple" (KAEDE)

Slots
by Thomas Worthington May 19, 2014

May 19, 2014

I notice that "Slots" are slated for addition in Pharo 3.0. Is there anywhere I can see which model of "slots" is being suggested? I'm not sure that slots, in the sense of Javascript, are a good idea generally and, in the broader context, I'm very unhappy with the idea of messing with Smalltalk's generally clean syntax by adding new language features. Could the desired effects be achieved by subclassing Behavour or somesuch high-level approach? -- Thomas Worthington

May 14, 2014

Hi All, I have some code that allows to access Twitter data using its REST API and the Streaming API (thanks Sven for helping me in It is rudimentary and needs more work, but it is useful for what I'm doing as a hobby in: http://www.tweetreport.com.ar/ I would like to share it but it is still mixed with some other code of my Twitter toy (thanks Alex , Pablo and all the Roassal team). So, if there is people interested in this code, I will separate and publish it. I just need to know if someone wants it to play, to avoid useless work. Best regards art

Video Tutorials about Pharo
by kilon alios May 2, 2014

May 2, 2014

Hello pharoers . I have created a playlist in youtube where in the past few days I am keep adding new tutorials about the basics of Pharo. https://www.youtube.com/watch?v=Ol5ivaEATLQ&list=PLqbtQ7OkSta0ULYAd7Qdxof85… For now I am focusing on the vary basics. So far the tutorials are 1) Why Pharo -> Explaining why I love Pharo and what Pharo is. 2) Install Pharo 3) Create a Class 4) Workspace Variables 5) Instance Variables 6) Temporary Variables I try to keep the duration at most around 10 minutes , if I can around 3-4 minutes. My goals is to focus on one or two features per tutorial. My focus for now is explaining the basics of Pharo the Language and Pharo the IDE. I hope however that after that I will have the energy and time to focus on Pharo libraries, like Nativeboost, Athens, Roosal , Sockets and many more. If my free time holds and I do not run out of steam, I should be able to produce around 30 - 60 hours per year of Video Tutorials that will be able to document a ton of Pharo functionality. Already the Playlist is over an hour long and I try to keep my tutorials focused entirely on the practical side. Your comments and support is greatly appreciated.

Re: [Pharo-users] Dynamic example for spec
by Stephan Eggermont May 1, 2014

May 1, 2014

Hi kmo, Thanks for your detailed response. You seem to have run into a number of issues I havenât seen yet while learning spec. Iâll take a look at resizing windows and see how to fix the issue. I have noticed the font size issue and assumed it is to be fixed real soon now. Iâll extend the example to include editing of existing instances. It was suggested that it would be good to have other examples, so I decided to try building a more business-application related one. I am used to dealing with domain models, and will revisit the names. Stephan

Pharo 3.0 Released!
by Esteban Lorenzano May 1, 2014

May 1, 2014

Dear World, Pharo 3.0 (http://www.pharo.org) is here. The past year seemed short as we got busy building more than usual. Many things have changed in Pharo. Here are the highlights: - The new modular Opal compiler is now the default compiler used in the system. - The Athens vector graphics canvas is now integrated and it supports Cairo rendering on all platforms. - Many tools have been rewritten using Spec, a new framework for building user interfaces. - Versionner and Kommiter are two of the new development tools. - RPackage, a new package mechanism got enhanced with tags and is fully integrated in the system. - The debugger model was rewritten to become modular, the inspector received a bump to support multiple views, and the Nautilus code browser supports tags, search and lot more improvements. - Morphic has seen many cleanings and improvements and the visual theme has been revamped. These are just the more prominent highlights, but the details are just as important. We have closed 2364 issues in Pharo 3 (compared with 1727 issues in Pharo 2). Take a moment to go through a more detailed recount of the progress: https://github.com/pharo-project/ChangeLogs/blob/master/Pharo30ChangeLogs.md Pharo is improving on many fronts. Just take a look at the code city of Pharo (built with Pharo for Pharo). Every building is a class, and the red bricks represent the modified methods in Pharo 3. Many things are changing but the system gets more stable. Moving from Pharo 2 to Pharo 3 is almost a matter of just loading the code. Remember that Pharo is your platform. We thank all the contributors of this release: Jean-Baptiste Arnaud, Simon Allier, Philippe Back, ClÃ©ment Bera, Alexandre Bergel, Torsten Bergmann, Usman Bhatti, Vincent Blondeau, Noury Bouraqadi, Johan Brichau, Camillo Bruni, Sven Van Caekenberghe, Damien Cassou, Nicolas Cellier, Guido Chari, Dimitris Chloupis, Bernardo Contreras, Ben Coman, Gabriel Omar Cotelli, Jordi Delgado, Tommaso Del Sasso, Gisela Decuzzi, Christophe Demarey, Sean DeNigris, Marcus Denker, Martin Dias, Erwan Douaille, Stephane Ducasse, Stephan Eggermont, Pablo Estefo, Luc Fabresse, Johan Fabry, Hilaire Fernandes, Nahuel Garbezza, Leo Gassman, Lucas Giudice, Tudor Girba, Thierry Goubier, Norbert Hartl, Dale Henrichs, Pablo Herrero, Nicolai Hess, Andre Hora, Alejandro Infante, Ricardo Jacas, Henrik Sperre Johansen, Denis Kudryashov, Pavel Krivanek, Juraj Kubelka, Laurent Laffont, Jannik Laval, Max Leske, David Lewis, Diego Lont, Esteban Lorenzano, Stefan Marr, Mariano Martinez Peck, Roberto Minelli, Hernan Morales Durand, Eliot Miranda, Fernando Olivero, Nicolas Papagna Maldonado, Nick Papoylias, Nicolas Passerini, Vanessa PeÃ±a, Nicolas Petton, Alain Plantec, Guillermo Polito, Damien Pollet, Jochen Rick, Benjamin Van Ryseghem, Ronie Salgado, Camille Teruel, Juan Pablo Sandoval Alcocer, Samir Saleh, Frank Shearar, Igor Stasenko, Aliaksei Syrel, Sebastian Tleye, Yuriy Tymchuk, Andres Valloud, Martin Walk, Hernan Wilkinson. And many many more who contributed indirectly, by reporting bugs, participating in discussion threads, providing feedback... Pharo 3.0 is the largest step we took since we started. Yet, itâs just a step. Expect more. Much more. Enjoy! The Pharo Team
