Using a TreePresenter
by Prof. Andrew P. Black Dec. 10, 2017

Dec. 10, 2017

I'm trying to use a (subclass of a) TreePresenter that is populated with FileReferences. I see that the current selection is, reasonably enough, a TreeNodePresenter, so I'm assuming that to set a selection programatically, I'm going to have to find the right TreeNodePresenter. So I've assumed a method allItemsDo: that I'm trying to write on my subclass of TreePresenter that will iterate through all of the TreeNodes and let me do stuff, such as looking at their #content to see if this is a node that I'm interested in. But I can't! The #roots method of TreePresenter doesn't give me the root TreeNodePresenters; it gives me the file references that they contain. How do I iterate over the TreeNodePresenters? Or am I going about this in entirely the wrong way? Andrew

HTTP request question for an arango driver
by Yann Lesage Dec. 10, 2017

Dec. 10, 2017

Hello, I write an driver for Arangodb . So like it's indicated in Arango documentation, I use the HTTP API.Â The repo is https://github.com/Valtena/Pharango Now, the problem : Arango using Znclient make around 1 000 requests/second. And the question : Are there any recommended pratice to have the better performance with ZNClient or a better way to perform lot of HTTP requests ? Thanks for your attention, Yann Lesage

KeyNotFound: key #nil not found in SystemDicitonary
by Seth Dec. 10, 2017

Dec. 10, 2017

So, I've been trying to save and close my image for a while now. It won't even just close without saving, it constantly pops up the error from this subject. I'm fairly new to all this, but I followed it to I think an Array of ClassSessionHandlers one of which is ClassSessionHandlers(nil) but I don't know how to get rid of it, I also opened the process browser and found a Morphic UI Process: nil which i tried to terminate. None of which seems to work. How to I get this nil value out of my image save / shutdown process? -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Simplest 'REPL'
by cheshirecatalyst Dec. 10, 2017

Dec. 10, 2017

I've recently picked up pharo, and am writing a small interpreter for a trivial language the details of which are unimportant. However I am looking for the simplest way to avoid having to use playground and Transcript to do something like | reader eval | reader := MyReader from: 'some stuff in my DSL'. eval := MyEvaluator from: reader. Transcript show: eval evaluate. I'm tired of having to change 'some stuff in my DSL' to a new expression and run it in playground. I don't really care which is easier, a Morphic with an input box at the bottom to put my expressions in with output up top, or a something like CommandShellTranscript (which i have looked at but is too complex for me to figure out how to get the desired result from). Basically I want to be able to use my DSL outside of playground, but still in image.

Hi, Here is an example that shows the distinction between edge and line: elementToVisualize := BlChicken chicken. elementToVisualize forceLayout. root := BlElement new constraintsDo: [:c | c horizontal matchParent. c vertical matchParent]. elementToVisualize allChildrenBreadthFirstDo: [ :each | | label | label := BlTextElement new text: each gtDisplayString asRopedText; background: Color white; effect: (BlDropShadowEffect color: (Color gray alpha: 0.5) width: 10 offset: 0@0). label userData at: #model put: each. root children detect: [ :child | (child userData at: #model ifAbsent: [ nil ]) = each parent ] ifFound: [ :parentLabel | | edge | edge := GtGraphEdge new from: parentLabel to: label. parentLabel constraints graph addConnectedEdge: edge. label constraints graph addConnectedEdge: edge ]. root addChild: label]. root layout: (GtGraphHorizontalTreeLayout new layered; verticalGap: 20). root With this we visualize the elements that make the chicken element demo: - we create a label for each element - we find the parentLabel corresponding to the parent element - we create an edge between the parentLabel and the current label The example gives us this: The edge is a constraint. It has no visual impact. And the graph layouts take the edge constraints into account. The cool thing is the GtGraphEdge is defined next to the graph layout classes, not in the core of Bloc. To add a visual impact, we have to create a separate line: Thanks for the question.

Hi, We are happy to announce GT Mondrian, a graph visualization engine built on top of Bloc. It is similar to the original Mondrian and the Mondrian from Roassal, but it is different in that it is built directly out of Bloc elements. This is interesting because it allows us to combine typical widgets with visualizations. The other interesting thing about it is that it validates the design of Bloc: right now, the implementation has 509 lines of code (excluding graph-specific layouts). The goal is to make visualization a first class citizen and an integral part of the IDE. The key ingredient that made this happen is that Bloc can now treat graph layouts, such as tree or force based, behave under the same rules as typical widget layouts, such as grid or flow. The challenge comes from the fact that a graph layout depends on the notion of edges between elements, and we did not want to have elements know about edges in the core of Bloc. The solution was to split the typical edge implementation in graph visualization libraries into two distinct concepts: â¢ Line is an element that draws the connections. â¢ Edge defines constraints imposed by connections between elements. Thus, edges form constraints, and constraints are what layouts deal with. That is one reason why elements in bloc have the ability of defining layout-specific constraints. Using this, we can nicely define edges between elements as a plugin to Bloc, but still be able to connect arbitrary elements. What's more, it turns out that we need constraints for other layouts as well. For example, an element in a grid layout might specify the span. The API of GT Mondrian is similar to the one from Roassal, but there are a few differences as well. These are described in the Pillar documentation available in the GitHub repo. The best way to experience GT Mondrian and its documentation is to load the GToolkit as described here: https://github.com/feenkcom/gtoolkit If you download the GT code through Iceberg, the documentation can be experienced live by inspecting: './pharo-local/iceberg/feenkcom/gtoolkit-visualizer/doc/mondrian/index.pillar' asFileReference Cheers, The feenk team -- www.tudorgirba.com www.feenk.com "Quality cannot be an afterthought."

A Genetic Algorithms Framework for Pharo
by Alidra Abdelghani Dec. 8, 2017

Dec. 8, 2017

Hi, I just implemented (the kernel of) a Framework for genetic algorithms (https://en.wikipedia.org/wiki/Genetic_algorithm <https://en.wikipedia.org/wiki/Genetic_algorithm>) in Pharo. Some of you could be dealing with optimisation problems. So maybe it could be useful for you. I implemented some basic functionalities : monoobjecitve, multi objective, a crossover and mutation operators, uniform selection... I also implemented some basic exemples ( mono/multi knapsack and travelling salesman) I still need to provide some documentation but there are lot of tests so it is easy to see how it works. I will add more operators from time to time. The code is intended to be as easy to reuse as possible. It is on Smalltalkhub : http://smalltalkhub.com/#!/~Alidra/GeneticAlgorithmsFramework/ <http://smalltalkhub.com/#!/~Alidra/GeneticAlgorithmsFramework/> Please take a look and tell me what you think. I will be pleased to help if you think the Framework can apply to your problem. just let me know :) Abdelghani
