[Pharo-project] Call for papers for Dyla'13: 7th Workshop on Dynamic Languages and Applications @ ECOOP
by Alexandre Bergel Feb. 26, 2013

Feb. 26, 2013

Dyla'13, 7th Workshop on Dynamic Languages and Applications Colocated with ECOOP, ECMFA and ECSA 1â5 July, Montpellier, France http://rmod.lille.inria.fr/web/pier/Events/Dyla13 !! Important dates - Submission deadline: April 19th - Notification: mid-May - Workshop: July 1st - Ecoop early registration: mid-May !! Abstract The advent of Java and C# has been a major breakthrough in the adoption of some important object-oriented language characteristics. This breakthrough turned academic features like interfaces, garbage collection, and meta-programming into technologies generally accepted by industry. Nevertheless, the massive adoption of these languages now also gives rise to a growing awareness of their limitations. A number of reactions from industry testify this: invokedynamic bytecode instruction has been included in latest Java virtual machine release; the dynamic language runtime (DLR) is gaining popularity; C# adopted dynamic as a valid static type. Gartner prognoses further growth (http://blogs.gartner.com/mark_driver/2008/12/10) of dynamic languages. Researchers and practitioners struggle with static type systems, overly complex abstract grammars, simplistic concurrency mechanisms, limited reflection capabilities, and the absence of higher-order language constructs such as delegation, closures and continuations. Dynamic languages such as Ruby, Python, JavaScript and Lua are a step forward in addressing these problems while getting more and more popular. Making these languages mainstream requires practitioners to look back and pick mechanisms up in existing dynamic languages such as Lisp, Scheme, Smalltalk and Self. Practitioners also need to further explore discover new dynamic approaches in the context of new challenging fields such as pervasive computing. The goal of this workshop is to act as a forum where practitioners can discuss new advances in the design, implementation and application of dynamically typed languages that, sometimes radically, diverge from the statically typed class-based mainstream. Another objective is to discuss new as well as older "forgotten" languages and features in this context. Topics of interest include, but are not limited to: - programming language extensions - programming environment extensions - executing environments - static and dynamic analyses - optional type-checking - meta-object protocols - reserve engineering - domain-specific languages/tooling - testing environments - live programming !! Targeted audience The expected audience of this workshop is practitioners and researchers sharing the same interest in dynamically typed languages. Lua, Python, Ruby, Scheme and Smalltalk are gaining a significant popularity both in industry and academia. Nevertheless, each community has the tendency to only look at what it produces. Broadening the scope of each community is the goal of the workshop. To achieve this goal we will form a PC with leading persons from all languages mentioned above, fostering participation from all targeted communities. !! Workshop Format and Submission Information The workshop will have a demo-oriented style. The idea is to allow participants to demonstrate new and interesting features and discuss what they feel is relevant for the dynamic-language community. To participate to the workshop, you can either - submit (before __April 19th 2013__) an article (ACM Tighter Alternate style http://www.acm.org/sigs/publications/proceedings-templates) describing your presentation and/or tool. Articles whose length ranges from 2 to 15 pages will be carefully reviewed by a program committee including but not limited to the organizers. Each accepted paper will be presented for 20 to 30 minutes and be published to the ACM Digital Library (at the option of each author) and the workshop's web site. The submission website is http://www.easychair.org/conferences/?conf=dyla2013. - or give a 10-minute lightning demo of your work. A dedicated session will be allocated for this, provided there is ample time available. A session on pair programming is also planned. People will then get a chance to share their technologies by interacting with other participants. !!

[Pharo-project] Metacello issues on Pharo 2.0
by Christophe Demarey Feb. 26, 2013

Feb. 26, 2013

Hi all, I have issues with Metacello on Pharo 2.0 If I load and run tests for the version used in Pharo1.4, it gives: (ConfigurationOfMetacello project version: '1.0-beta.31.1.4') load: 'Tests' Metacello packages shipped with Pharo 2.0 are all packages derived from the latest stable Metacello baseline (1.0-beta.31.1.5) except the MetacelloToolBox. If I load and run tests packages with version described in the latest stable Metacello baseline (1.0-beta.31.1.5), i.e. : Metacello-TestsCore-DaleHenrichs.14 and Metacello-TestsMC-dkh.351, it gives (Pharo 2.0 #20547): So, it seems there are some problems. Do we use the rigth versions of Metacello packages? Regards, Christophe.

[Pharo-project] Morphic View UI and Pharo Tabbed Pane IDE on Pharo 2.0
by S Krish Feb. 26, 2013

Feb. 26, 2013

HI, Just started to use Pharo 2.0 and find it nice overall. The package loading time, is something I need to recheck, profile and see, but feel there is a lag. Few other minor issues, nothing major so far. Smooth integration of the work I had done in 1.4: Pharo Morphic View and Pharo Tabbed Pane IDE. Try it out and let me know: http://skrishnamachari.wordpress.com/2013/02/26/pharo-2-0-morphic-view-and-… Will come back on the Pharo Tablet like interface that I have talked of earlier as also the integrated Brett Taylor like dynamic UI construction...

[Pharo-project] ImageDirectory DirectoryDoesNotExist
by Sean P. DeNigris Feb. 26, 2013

Feb. 26, 2013

Several times in #20567, I've been working for a while, and then all of a sudden: - I lose my temp names - Clicking on Packages in Nautilis -> ImageDirectory DirectoryDoesNotExist - Image save -> Error: Failed to write image file (disk full?) I wasn't doing anything unique at these times that I can point to... Is anyone else experiencing this? Thanks, Sean -- View this message in context: http://forum.world.st/ImageDirectory-DirectoryDoesNotExist-tp4672135.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] [ANN] Pharo Online Help 1.1. for Pharo 2.0 (now with Markdown support and tutorials)
by Torsten Bergmann Feb. 26, 2013

Feb. 26, 2013

Hi, the Pharo Online Help project for Pharo 2.0 now also supports markdown [1] for writing documentation and tutorials. Markdown is an easy-to-read, easy-to-write plain text format that is translated into X(HTML). If you are in Pharo 2.0 just go to Tools -> ConfigurationBrowser and load PharoOnlineHelp. In the panel select a port or just click on "Start server". Now point your browser http://localhost:8080 Attached you will find some screenshots. The help system also includes an intro to Pharo and a start for a simple Smalltalk introduction (based on the old beginners workspace). Next steps: - maybe we can extend the integrated API browser to support webdoc [2] - move to SmalltalkHub project [3] - continue with Pharo and Smalltalk tutorials for beginners - better support for resources like images, js, css, ... (currently hard coded in OHFileRequestHandler) Feel free to help, code is on http://ss3.gemstone.com/ss/PharoOnlineHelp.html Thanks T.

[Pharo-project] Weird red crossed rectangle with Spec on Refactoring ... accessors
by phil＠highoctane.be Feb. 25, 2013

Feb. 25, 2013

In #20571... Windows PharoVM I tried to do a Refactor .. accessors. then I got the spec related message with model: ... as reported before. Ben told me that it was something with WidgetBuilt class missing. All right, WidgetBuilt thing needed in the image for Spec (don't know why it isn't there but still, I only do system updates). Now, I went to Monticello, and saw Spec from Markus.88 which I browsed and it contained the WidgetBuilt. So, I merged it. And now, the feature works, but instead of having checkboxes for my accessor methods, I do get a red cross with nothing selectable. Is anyone having the same behavior in the image? Phil
