Roassal 2 disable browser and vis. animations
by Robert Kuszinger Aug. 27, 2016

Aug. 27, 2016

Hello Group, since yesterday I'm investigating the Roassal examples. Udderlying system is: - Pharo-50761.image - pharo-spur --version 5.0 #1 Wed May 4 11:54:28 CEST 2016 gcc 4.6.3 [Production Spur ITHB VM] CoInterpreter VMMaker.oscog-eem.1855 uuid: d8e4a3c2-a3bf-4adc-b224-8012903a1ef4 May 4 2016 StackToRegisterMappingCogit VMMaker.oscog-eem.1855 uuid: d8e4a3c2-a3bf-4adc-b224-8012903a1ef4 May 4 2016 https://github.com/pharo-project/pharo-vm.git Commit: b8ec25a570d7539653e1d793e97609adb509aaed Date: 2016-05-04 11:14:22 +0200 By: Esteban Lorenzano <estebanlm(a)gmail.com> Jenkins build #589 Linux pharo-linux 3.2.0-31-generic-pae #50-Ubuntu SMP Fri Sep 7 16:39:45 UTC 2012 i686 i686 i386 GNU/Linux plugin path: /usr/share/pharo/spur/ [default: /usr/share/pharo/spur/] Roassal is loaded like this: - Gofer it smalltalkhubUser: 'ObjectProfile' project: 'Roassal2'; configurationOf: 'Roassal2'; loadStable. In the office (yes, in worktime :) ) I also tested on Windows 7. I only click through all the built in Roassal examples. I AM IMPRESSED! Very powerful system, even the GIS (map) part with OSM integration (VOW!) Anyway, on windows it crashed many times (On WIndows I downloaded this: http://moosetechnology.org/res/download/moose_suite_6_0-win.zip) I observed that windows crash moment was always some kind of animation (window transition animation of the Roassal exmaples browser or visualization animation like pan or zoom). Question: - Is there a way to disable Roassal visualization animations? - is there a way to disable window component animation in the Roassal Example Browser? (When clicking on the dots and moving between examples list and the visualization example itself, for example) I wonder if it would make the windows run more stable. On Linux it is OK but also painfully slow (ok, old machines). I prefer animationless repaint of the visualization canvas and window transitions. thanks Robert

support for Croatian language
by Gour Aug. 27, 2016

Aug. 27, 2016

Hello, while researching how to make fonts in Pharo display Croatian characters, I've noticed that in Settings --> Appearance --> Standard fonts Croatian is not listed and I have to use Slovene (Slovenian) , so wonder what is required in order to add 'support' for it? Sincerely, Gour -- The working senses are superior to dull matter; mind is higher than the senses; intelligence is still higher than the mind; and he [the soul] is even higher than the intelligence.

renaming packages with iceberg or metadata-less gitfiletree
by Peter Uhnak Aug. 27, 2016

Aug. 27, 2016

Hi, is it now possible to rename package without losing history with iceberg or metadata-less gitfiletree? Normally git can easily handle this, but it seems that on pharo-side it needs to be handled explicitly? Thanks, Peter

[ANN] TaskIt v0.2
by Guille Polito Aug. 26, 2016

Aug. 26, 2016

Hi all, With Santi we wanted to share a new release of TaskIt, a concurrency management library for Pharo. TaskIt development is done entirely in github, using iceberg. Works like a charm. Please find below attached the changes log with more information. Cheers, Guille & Santi TaskIt https://github.com/sbragagnolo/taskit TaskIt is a library that ease Process usage in Pharo. It provides abstractions to execute and synchronize concurrent tasks, and several pre-built mechanisms that are useful for many application developers. This chapter explores starts by familiarizing the reader with TaskIt's abstractions, guided by examples and code snippets. At the end, we discuss TaskIt extension points and possible customizations. ChangesLog TaskIt v0.2 Major Features * Task Runners o NewProcessTaskRunner o LocalProcessTaskRunner o Worker o WorkerPool * Futures with callbacks * Future combinators * Future synchronous access * Services Infrastructure * Travis CIhttps://travis-ci.org/sbragagnolo/taskit * Documentationhttps://github.com/sbragagnolo/taskit/blob/master/README.md Minor changes log (from commits) * Enhanced class comments * TKTWorker processes are terminated in case the worker is collected. See Issues#8 <https://github.com/sbragagnolo/taskit/issues/8>and#5 <https://github.com/sbragagnolo/taskit/issues/5> * Process Dashboard. - Adds TKTTaskItProcessProvider by default with the extension package - Hides job and task fields since there are not reachable any more.

Set on Attribute
by Sean P. DeNigris Aug. 26, 2016

Aug. 26, 2016

Say I have a collection like #('ab' 'ac' 'ba' bc') and I want to condense it so that a certain attribute is unique. In this example, say the first character, so I want one object where the first character is $a and one $b, but I don't care which object i.e. 'ab' or 'ac' for $a, but not both. Is there an elegant way to do that? ----- Cheers, Sean -- View this message in context: http://forum.world.st/Set-on-Attribute-tp4912672.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

IIS and Pharo web service solutions
by Robert Kuszinger Aug. 25, 2016

Aug. 25, 2016

Hello! 1)--------------------- I've successfully worked out how to operate Pharo / Seaside web services behind IIS on Windows Server 2008 (R2) but maybe works on later editions as well. I could summarize it in a "HOWTO" if there is interest or even post it to include in a documentation. (Pharo as a service on Windows, IIS modules to install, how to make it and how to configure proxy / url rewrite) 2)--------------------- Since failed finding an usable binary for nginx uploader module on windows I worked out a method (not really a piece of software) how to use NeatUpload (.NET solution) together with Pharo/Seaside to receive hundreds of megabytes of uploads on Windows servers. If there is interest I'm also ready to document and post it here or somewhere. Please sign any interest here or in private email and then I'll create the docs. Thanks for the many help from many of you during the last two months :) Robert

[ann] Lam Research evaluates Pharo
by Tudor Girba Aug. 25, 2016

Aug. 25, 2016

Hi, We are very happy to make the following announcement: Lam Research, a leading supplier of wafer fabrication equipment and services to the global semiconductor industry, is an experienced user of the Smalltalk programming language. Smalltalk is a key component in Lam's software control system for a broad range of the equipment it manufactures. Tudor Girba is a leading member of the tools and environment development effort in Pharo, having architected the Glamorous Toolkit for live programming. Eliot Miranda is author of the Cog virtual machine that underlies Pharo and other Smalltalk dialects. Lam has engaged Tudor and Eliot to explore potential enhancements in Lam's use of Smalltalk. These enhancements range from running highly optimized Smalltalk on low cost, single board computers, to enhancing Lam's Smalltalk development practices with state-of-the-art live programming. During the engagement, Tudor and Eliot successfully moved a key communication component of the control system to Pharo. It was a challenging task aimed at extending the reach of Lamâs system to the Pharo world including the option of executing on ARM processors. Cheers, Tudor Girba, Eliot Miranda and Chris Thorgrimsson

[ann] seaside gtdebugger
by Tudor Girba Aug. 25, 2016

Aug. 25, 2016

Hi, As presented at ESUG on Monday, we now have a custom GTDebugger for Seaside. This was built by Andrei as an initial experiment. As we do not know much about Seaside-specific debugging problems, we asked a couple of Seaside users to describe issues that would be useful to be addressed in the debugger, and Andrei allocated some 4h to construct some of these in an custom debugger for Seaside. Two of the issues that popped up are: - get a quick view of the current request context - get an overview of the current component nesting They are now addressed like depicted in the screenshot below. You should look at this debugger as a beginning. Beside the current basic extensions one added value is that we now have the scaffolding to build more. Please take a look at it and letâs try to identify more concrete issues that might be addressed. It would be great if this would be taken over by the Seaside community. The debugger can be loaded on top of a Pharo 6.0 with Seaside inside like this: Gofer new smalltalkhubUser: 'Moose' project: 'GToolkit'; package: 'GT-SeasideDebugger'; load. #GTSeasideDebugger asClass register Cheers, Doru -- www.tudorgirba.com www.feenk.com "The coherence of a trip is given by the clearness of the goal."

Hi, Can anyone tell me if there is a Websocket implementation for Pharo? Cheers, Doru -- www.tudorgirba.com www.feenk.com "From an abstract enough point of view, any two things are similar."
