Moose 5.1 image getting really sluggish after graphing a bigger dataset

by Manfred Kröhnert

Hi everyone, after having access to a machine running OS X 10.10.2 I started to give Moose 5.1 a try for some initial data analysis. I used Pharo Launcher (build #24) and downloaded the Moose image with buildnumber 304. The task is to read a CSV log file containing around 130000 entries, each containing a timestamp, a cpu usage number, and some other information. Everything works as expected, but the responsiveness of the image drops dramatically after executing the script in Playground with Cmd+Shift+g. After evaluating the script it takes several seconds to get a response to any action such as opening the world menu or switching tabs in the playground. Is this because I am doing something very inefficient (most probably) or does this problem occur more often? Here is the script I am using: cpuReader := NeoCSVReader on: (cpuFile readStream). cpuReader separator: $|. cpuHeader := cpuReader readHeader. cpuData := cpuReader upToEnd. g := RTGrapher new. g extent: 300@200. ds := RTDataSet new. ds points: (cpuData collect: [ :each | | timestamp cpuUsage | timestamp := (each at: 1) asNumber. cpuUsage := (each at: 4) asNumber. Array braceWith: timestamp with: cpuUsage]). ds x: #first. ds y: #second. ds connectColor: Color blue. g add: ds. g addDecorator: RTHorizontalTickLineDecorator new. g addDecorator: RTVerticalTickLineDecorator new. g build. g view canvas. I also noticed that the 'Meta' representation of an object looks very crammed since it does not use the full size available in the tab. Should issues like this be reported somewhere else? Thanks for taking a look at this, Manfred

500 000 elements in Roassal [we made it :-) ]

by Alexandre Bergel

Hi! Just to share our latest feature. We have implemented a simple mechanism in Roassal to prevent the environment to be sluggish with many elements. The class RTCache has the effect to remove the elements from a view, create a bitmap from them, and add the bitmap to the view. Simple and effective. Consider the following script: -=-=—=-=-=—=-=-=—=-=-=—=-=-=—= v := RTView new. v @ RTDraggableView. colors := ColorPalette qualitative colors: 8 scheme:'Set1'. elements := (RTEllipse new color: [ :aValue | colors atRandom alpha: 0.01 ]; size: #yourself) elementsOn: ((1 to: 500000) collect: [ :vv | 10 atRandom + 5 ]). elements do: [ :e | e translateTo: 500 atRandom @ 500 atRandom ]. v addAll: elements. RTCache new cacheView: v. v -=-=—=-=-=—=-=-=—=-=-=—=-=-=—= Without the line "RTCache new cacheView: v.” Pharo would be completely unresponsive. 500 000 elements is quite a lot. The drawback is that all interaction with the elements are lost. I have some idea on how to add them back. We will work on this in future work.

Tag cloud around an avatar

by Offray Vladimir Luna Cárdenas

Hi, I would like to create a tag cloud around an avatar taken from the public profile of a social network (twitter). For that I would like to know if is possible to make 3 things in Roassal: 1. Put a tag cloud with some layout/form (for example around an object). 2. Put a raster image (the avatar) in the center of that tag cloud. 3. Exclude some words from the tag cloud. I will be making my explorations tonight and tomorrow morning, but any pointer in the right direction will be greatly appreciated. Cheers, Offray

spotter scenario

by Alexandre Bergel

Hi! I am facing a scenario that spotter does not seem to help. Consider the following scenario: - Consider the Moose Panel menu: - I would like to know how to add a new entry in that menu. Best is to look for existing example. So, I would like to see the class behind the entry “import hismo model from MSE files”. I highly suspect that the class contains the word “Hismo” and “Import” in it. Well, let’s see what spotter gives me. - I open Spotter and enter: hismo import Instead, I open Nautilus, typed Importer, and found it: It is MooseHismoImporter. Well, from this class, I end up in MPImportHismoCommand, which is exactly what I am looking for Did I miss anything obvious in my reasoning?

The service started in 2006 with the goal of providing a scalable and reliable way of hosting open source projects. Since that time, millions of people have contributed to open source projects hosted on the site. But a lot has changed since 2006. In the past nine years, many other options for hosting open source projects have popped up, along with vibrant communities of developers. It’s time to recognize that Google Code’s mission to provide open source projects a home has been accomplished by others, such as GitHub and Bitbucket. We will be shutting down Google Code over the coming months. Starting today, the site will no longer accept new projects, but will remain functionally unchanged until August 2015. After that, project data will be read-only. Early next year, the site will shut down, but project data will be available for download in an archive format. As the owner of the following projects, you have several options for migrating your data. pier google-summer-of-code-2008-squeak google-summer-of-code-2007-squeak bluecoral seasidexul moose-technology The simplest option would be to use the Google Code Exporter, a new tool that will allow you to export your projects directly to GitHub. Alternatively, we have documentation on how to migrate to other services — GitHub, Bitbucket, and SourceForge — manually.

DNU: receiver of "allAttributes" is nil

by Alexandre Bergel

Hi! I am building a small meta-models for c++ analysis. I have created a class called PCPPFunction, a subclass of MooseEntity. (I know there is a FAMIXFunction, but the PCPPFunction is radically different from FAMIXFunction because if contains many information about dynamic analysis). When I visualize instance of PCPPFunction, and I click on one, I get an error: I guess I did not properly define the metamodel behind. But I do not see what is wrong. Here are the definitions: PCPPObject class>>annotation <MSEClass: #PCPPObject super: #MooseEntity> <package: #ProfilerCPP> ^ self PCPPFunction class>>annotation <MSEClass: #PCPPFunction super: #PCPPObject> <package: #ProfilerCPP> ^ self Is this not enough?

GLMTreePresentation filtering roots only

by Usman Bhatti

Hi, I would like to apply filter only on the root items in a tree presentation and not on all children. Computing children take a bit of time for each node, which is acceptable for each root. However, accumulated computation time make the filtering un-usable. I could not find a possible way to avoid the filter computation for the children in GLMTreeMorphNodeModel>>shouldBeDisplayedByText with the current implementation. I can propose a fix. Let me know what you think. regards. usman

Datathon for development in Paris

by Serge Stinckwich

Dear all, something that might interest some of you. There will be a datathon organized in Paris in collaboration with the MIT about data & development in African countries from April 7th to 9th. Some companies and NGOs will provide open data. Orange, the telecom provider will provided some data about communication between local antennas and also trajectories log of people. I have the idea of having a small team using ROASSAL for participating to the datathon and doing some nice vizualisations. Anyone interested to made a team ? You could find more information about this event here: http://simplon.co/blog/2015/3/7/datathon-data-for-development-rdv-les-7-8-e… sorry only in French.

using spotter to navigate through the file system

by Tudor Girba

Hi, Here is a little post that describes how you can use GTSpotter to navigate through the file system: http://www.humane-assessment.com/blog/searching-file-system-with-gtspotter/ If you combine this with the GTInspector ability of allowing you interact with the file references, you get a pretty powerful tool: http://www.humane-assessment.com/blog/browsing-files-with-gtinspector/ This is probably the simplest 3-minute demo you can give to a newcomer :).

About merging metaclass and methods extraction

by stepharo

Hi I'm wondering how we handle the following case: - we have a method with the same name on instance and class - we import by merging class and metaclass. I remember that I payed attention to that for ClassVariable but I do not see how I handle it in the SmalltalkImporter. Does one of you remember? Stef

smaller configurations vs groups [was Re: Pillar and GT tools in Pharo4]

by Tudor Girba

Hi, I summarize below why I think fine grained configurations should be preferred to groups. The group is not a first class configuration, although it can be depended on. If you depend on a group of a configuration, it's harder to understand the consequences and it's harder to build tools for it. Consider the graph below representing the dependencies starting from ConfigurationOfMoose #development: [image: Inline image 2] It's a simple representation of dependencies, and it makes the maze of configurations easier to grasp. The interesting thing about it is that by showing a configuration node only once, you can see how multiple other projects depend on it. For example, HashTable is being depended on by two distinct configurations. You can also see that Magritte depends on Grease, but you do not see that it only depends on the Core group. To do that, you have to look at the details of the edge. We used to have groups in GT, however, after a while we moved to more fine grained configurations. As a consequence, you can see that GlamourCore (which used to be a group in Glamour) is being depended on by three different configurations. Using first class configurations makes tool building (like representation, navigation or release) easier. You could argue that we could represent a Group as node, however, even then you would not be able to see dependencies between groups that reside within the same configuration because groups are not first class configurations that can explicitly define dependencies, they are just groups. Groups might provide an apparent ease of use for quick things, but I strongly believe that they are an unessential construct and that if we would not use them, tools would become cheaper and more effective.

MooseModel>>numberOfPackages ?

by Alexandre Bergel

Hi! There is the following method in Moose: -=-=-=-=-=-=-=-=-=-=-=-= MooseModel>>numberOfPackages <MSEProperty: #numberOfPackages type: #Number> <MSEComment: 'Total number of packages'> ^ self isSmalltalk ifTrue: [self privateState propertyAt: #numberOfPackages ifAbsentPut: [self allPackages size].] ifFalse: [self privateState propertyAt: #numberOfPackages ifAbsentPut: [self allNamespaces size].]. -=-=-=-=-=-=-=-=-=-=-=-= The fact this method is defined in MooseModel seems quite wrong to me. Why should this method be in that class? #numberOfClasses is defined somewhere else. I now have a moose model that contains profiling data, and the notion of package is meaningless in my context.
