[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."

Google building new OS with Dart
by askoh Aug. 24, 2016

Aug. 24, 2016

It became news a few days ago. It is called Fuchsia and is meant to run on all devices from IoT on up. The interesting thing is that Dart will be the main language. The developers promise to make Fuchsia run on Raspberry Pi 3 shortly. Since Dart is pretty close to Smalltalk, how can Smalltalk be the GUI for Fuchsia? How can it take advantage of Dart VM? Is this an opportunity for Smalltalk to make an impact? Let's brainstorm. All the best, Aik-Siong Koh -- View this message in context: http://forum.world.st/Google-building-new-OS-with-Dart-tp4911649.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Keyboard work flow?
by epeld Aug. 23, 2016

Aug. 23, 2016

Hello! Is it possible to get by using ONLY the keyboard in the standard development components? Here are some workflows that I frequently use and would like to perform without mouse if possible: 1. Use Spotter to browse a class 2. Define a new method. That is, allow me to immediately focus the source code editor so I can start typing a new method or 1. Use Spotter to browse the implementation of a method 2. Edit its source code and accept 3. Now recategorize or rename or create new class etc etc. (the problem here is that the source code editor will shadow all the shortcuts I normally have in the browser, e.g CMD-M CMD-M would normally recategorize the method, but now this brings up the implementors list instead. Thanks! -- View this message in context: http://forum.world.st/Keyboard-work-flow-tp4912091.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Spec > TreeModel: Updating the tree selection after a deletion
by Offray Vladimir Luna CÃ¡rdenas Aug. 23, 2016

Aug. 23, 2016

Hi, I have a Spec TreeModel to represent the GUI of a grafoscopio notebook. The message that deletes nodes is something like this: ============ GrafoscopioNotebook>>removeNode | nodeToDelete | nodeToDelete := tree selectedItem content. nodeToDelete parent removeNode: nodeToDelete. tree selectedItem: tree selectedItem parentNode. tree needRebuild: true. tree roots: tree roots. self buildWithSpecLayout: self class defaultSpec. ============= And its working fine in the sense that it deletes the selected node, but after the deletion the contents of the old node are showed no matter if I change the node selection on the tree. I would like to manage selections in a smart way, so if I add a new node to the notebook, the new node gets the selection. If I delete a notebook node, the previous node gets selected or the parent if no more siblings are encountered and so on. There is some simple example to look for, about managing and updating selections in a TreeModel interface? Thanks, Offray
