Roasal: Putting a white background instead of a transparent one in word clouds

by Offray Vladimir Luna Cárdenas

Hi, I have finally finished the first part of my visualization project of political discourses on Twitter. You can see the details here: http://mutabit.com/offray/static/blog/output/posts/visualizing-politiciansp… (As you can see Pharo was not used to extract the data, just to scrap it, structure it and visualize it). The politicians tag cloud look nice if the background is white, because the png background is transparent, but if you share it on Twitter, the black background makes the tag cloud invisible. I could use image editing programs to change the background from transparent to white, but I would like to know if there is a way to make that change inside Pharo/Roasal. Thanks for all your support in making this ideas possible. Cheers, Offray

apiwave - Discover and track APIs

by Andre Hora

Hello guys, I would like to present you apiwave <http://apiwave.com>, a tool to discover and track APIs. While it is easy to know how “popular” is a project in number of contributors or fans, it’s quite hard to know how many clients are actually using it. To cover that, we performed an analysis on the most used APIs in top 500 GitHub java projects. On apiwave <http://apiwave.com/> you can dig into this data, and explore how more than 250K frameworks/packages/APIs are actually being used over time. You can read a bit more in this post <https://apiwave.wordpress.com/2015/04/10/most-used-apis-in-top-500-github-j…> . Even if the tool is not directly related with Moose, I think it could be interesting for some developers here :) Feel free to provide feedback. best regards, -- Andre Hora

GT: Playground Missing Refresh Button

by Sean P. DeNigris

It only appears when diving starts from an inspector, not from a playground. Will playgrounds get this button, too? It took me a while to figure out why the button was missing in some cases. After you're a few panes deep, it seems irrelevant how the first code was evaluated... ----- Cheers, Sean -- View this message in context: http://forum.world.st/GT-Playground-Missing-Refresh-Button-tp4818761.html Sent from the Moose mailing list archive at Nabble.com.

Wrong version loaded using Metacello

by Jan Kurš

Hi All, In ConfigurationOfPetitParser, there is a stable version 1.10 for Pharo 3.0 which says to load version PetitIndent.JanKurs.1. version110: spec <version: '1.10' imports: #('1.6-baseline' )> spec for: #'common' do: [ .. package: 'PetitIndent' with: 'PetitIndent-JanKurs.1'; .. Yet, if I load the stable version from Pharo 3.0: Gofer new smalltalkhubUser: 'Moose' project: 'PetitParser'; configurationOf: #PetitParser; load. (ConfigurationOfPetitParser project version: '1.10') load. I got PetitIndent.JanKurs.11 loaded, which is very unfortunate, since other packages are kept old. Does anyone knows why is this?

GT Inspector: Inst Vars Not Bound

by Sean P. DeNigris

1. Go "#(1 2) asOrderedCollection" 2. In the right pane, type "firstIndex" and Go again Either nothing happens or another pane opens on nil. "firstIndex" stays in red, showing that it's not recognized.

Report about the D4D datathon challenge

by Serge Stinckwich

Dear all, this is a small report about the RESILIENCE team using Pharo&Roassal for the D4D datathon challenge: http://www.d4d.orange.com/en/home The idea was to use mobile network data from Senegal provided by Orange company in order to solve some development problems. The amount of data provided by Orange was really huge, something like 66 Gb: we have the number and the durations of calls between each pairs of GSM antennas in Senegal (1666 different antennas) and also some information about the mobility of people. You can find more information about the data here: http://arxiv.org/abs/1407.4885 We try to extract some data from August 2013, because we know that some floods occurs at that time in Dakar. Our main objective was to to be able to visualise mobility and communications patterns with ROASSAL to see if there is any differences before and after the floods. We had a lot of problems to solve in a short period of time :-) At the beginning, we couldn't open huge files with Pharo. Only open a file that is around 3.4Go is impossible. Pharo says that the file does not exist. Thierry tells us that us that one must compile the VM with -D_FILE_OFFSET_BITS=64. (the Cog VMs are also built with -D_GNU_SOURCE). Why this is not done by default ? After that we decide to split the files in many smaller files and we try to use a mySQL database and various other tools but still have many troubles because of the size of the data ... At the end, we have done some visualisations but only on a tiny portion of the data on one day (one day is around 100Mb of data). You could find some visualisations done by our team here: https://twitter.com/sergestinckwich/status/586178094215606273 Managing huge amount in Pharo and also ROASSAL is still a challenge and we definitively need more tools in this area. We had some problems with ROASSAL: bugs with RTEdgesBuilder (Alvaro can you send a report to Alex about that ?), to much time to process some viz, ... At the end, our team receive the honorary price: https://twitter.com/sergestinckwich/status/585866625745887232 This is a brief description of our project. ========================================================= Project name: RESILIENCE Team members: Clémence Douard (ENSCI), Onil Goubier (CIRELA), Alvaro Peralta (LabU / Chile University), Aurélie Thouron (ENSCI), Serge Stinckwich (IRD / UMMISCO) The main concern of this project is to improve resilience after an environmental crisis in a southern city. During the preparedness phase before crisis, records of inhabitants habits (like patterns of mobility or communications) are done in order to characterize the situation before the crisis. Assessments of the improvements will then be done by providing suitable visualizations of the resilience dynamic. The goal is to help citizens to represent these improvements and to take advantage of them in their daily lives. We took as an example the city of Dakar during the flooding that occurred in August 2013. The data used are those of the dataset 1 (communication between antennas) and 2 (user mobility) provided Orange. We use this information, coupled to OSM, and other data related to floods of August in Dakar to construct maps and indicators to show resilience. Visualizations are made with agile visualization platform Roassal: http://agilevisualization.com/ ========================================================= I would like to thank all the team members and also the people who help us remotely: Alexandre Bergel (ObjectProfile/Chile University) and Thierry Goubier (CEA) I would like to thank also the SIMPLON team and ORANGE for organizing such a nice event. Regards, -- Serge Stinckwich UCBN & UMI UMMISCO 209 (IRD/UPMC) Every DSL ends up being Smalltalk http://www.doesnotunderstand.org/

new graph algorithms

by Christophe Demarey

Hi, A few days ago, I added new graph algorithms into MooseAlgos but I did not communicate about that. I added 2 complementary algorithms: - MalGraphReducer : it takes as input a graph and ouputs a graph without circuits. Nodes forming a circuit (or cycle if you prefer) are merged into a single node. A merge node has a reference to merged nodes. It uses the MalTarjan algorithm. - MalTopologicalSorting : the well known graph sorting algorithm that can only be applied on graphs without circuits (cycles). the latter could be useful for some layouting strategies of graphs for example. Regards, Christophe.

Force based layout progress bar

by Natalia Tymchuk

Hello. As we all know Force based layout is quite slow. For example if I use it for more that 200 points it takes ages and during that time I’m not even sure if it works or no. So I wonder maybe it will be better to draw progress bar during the time it works? Thanks. Best regards, Natalia

Composing graphs

by Alexandre Bergel

Hi! Here is a small script I have written for a robotic application. You can use RTComposer to put several graphs next to each other. There is nothing new in that respect, but it is worth illustrating it once in a while... Here is an example: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= force := { {'x' . 3 }. { 'y' . 4 } . { 'z' . 5 } }. torque := { {'x' . 5 }. { 'y' . -10 } . { 'z' . 8 } }. composer := RTComposer new. "-------------" "Force" b := RTGrapher new. b view: composer view. ds := RTStackedDataSet new. ds points: force. ds y: #second. ds barShape width: 30. ds histogramWithBarTitle: #first rotation: 0. b add: ds. b axisX noLabel; noTick. b build. composer group: #force. "-------------" "Torque" b := RTGrapher new. b view: composer view. ds := RTStackedDataSet new. ds points: torque. ds y: #second. ds barShape width: 30. ds histogramWithBarTitle: #first rotation: 0. b add: ds. b axisX noLabel; noTick. b build. composer group: #torque. "-------------" "Doing the layout of the graphs" composer move: #force onTheLeftOf: #torque. composer nameGroup: #force as: 'Force'. composer nameGroup: #torque as: 'Torque'. composer setGeneralTitle: 'Wrench'. composer view. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= You obtain: You need to update Roassal for this last example (I have added #setGeneralTitle:).

Labels on X

by Demian Schkolnik

Hi all! I want to make a little graph of a vector, with bars: | b ds labels | b := RTGrapher new. b extent: 300 @ 200. ds := RTStackedDataSet new. ds points: { 2 . 2.3 . 1.2 }. ds barShape width: 40. b add: ds. labels := #(x y z - -). b axisX numberOfLabels:labels size-1. b axisX numberOfTicks:labels size-1. b axisX labelConvertion: [ :item | labels at:item +1]. b build. ^ b view The code above writes the x 2 times. I just want an x, y and z under each one of the bars. Also, I havo to do the 'item+1' thing because it somehow starts at 0, and smalltalk arrays start at 1... Thanks!

Issue 1119 in moose-technology: progress bar when using the force based layout

by moose-technology＠googlecode.com

Status: New Owner: ---- Labels: Type-Defect Priority-Medium Component-Roassal New issue 1119 by alexandr...(a)gmail.com: progress bar when using the force based layout https://code.google.com/p/moose-technology/issues/detail?id=1119 An alternative is to have another subclass, such as RTForceBasedWithProgressBarLayout But this is not idea, because the progress bar should be by default Pharo. And on VisualWorks no. Another alternative, and the cleanest one I believe, is to have event generated to every X steps. You can have whatever you wish as a callback, moving the progress bar or not.

[Roassal 2] updating CompositeShape

by Jan B.

Hello I am trying to work with composite shapes, but I encountered a problem. Let's say I need to create a circle... and in the center of it is another, smaller, circle with label (but I need it to be centered according to both label and smaller circle, that's why I decided to use composite shapes instead of RTLabelled). I am able to create it just fine, problem is when I call update on its RTElement. I'm not sure whether I am even supposed to do it, but I think I should be. I start with just the inner circle with label: | composite view | composite := (RTLabel new text: 'label'; yourself) + (RTEllipse new size: 10; yourself). composite horizontal. element := composite element. view := RTView new. view add: element; open. element update. Before element update, it looks fine, but when I call update, composite layout (horizontal) gets lost. Let's say I can ignore this problem (which I can't), and I will try the same thing with whole shape | composite view subcomposite | subcomposite := (RTLabel new text: 'label'; yourself) + (RTEllipse new size: 10; yourself). subcomposite horizontal. composite := (RTEllipse new size: 50; color: Color transparent; borderColor: Color black; yourself) + subcomposite. element := composite element. view := RTView new. view add: element; open. element update this time I get exception MessageNotUnderstood: TRCompositeShape>>text:on: I will appreciate any help, either by fixing something if it is broken, or explaining how to reach my goal the correct way.

The Grapher charting engine

by Alexandre Bergel

Dear all, As many of you know, Grapher is a über-cool charting engine, part of Roassal. For people who do not know what Grapher is, here is a (compelling we hope) example: Which is obtained by the following script: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= | b colors points ds pts dec lb | b := RTGrapher new. colors := Array with: Color red with: Color blue. points := OrderedCollection new. colors do: [ :c | ds := RTStackedDataSet new. pts := ((1 to: 100) collect: [ :i | 50 atRandom - 25 ]) cumsum. points add: pts. ds points: pts. dec := RTDevVarDecorator new. dec moveBehind; desviation: 0.5; color: (c alpha: 0.3); points: pts. ds connectUsing: (RTLine new color: (c alpha: 0.5); width: 1 ). b add: ds. b addDecorator: dec. ]. b axisX; axisY. b build. lb := RTLegendBuilder new. lb view: b view. colors doWithIndex: [ :c :i | lb addColor: c text: 'Series ', i printString ]. lb build. b view @ RTZoomableView. b view -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= In our grand vision of making Roassal the best visualizing engine of the Universe (we also know to be modest time to time, but not today :-), Grapher will play a very important role. We would like to stabilize Grapher and make it sure it happily fits everybody needs. You can help on it: - When you are tempted to look at the dark side of the planet (this is where R, JFreeChart, gnuplot, D3 and all their friends live), let us know. We will make sure to make you are happy again. - Share your wishlist with us. We already have a long todo list, but your opinion does matter and will take it seriously - we are open to contributions, which could be financial, bug fixe, enhancement, or simply encouragement. I am very happy to be surrounded by very smart engineers. Your encouragement are making them happy :-) Cheers, Alexandre, in the name of the Object Profile Team NB: sorry for the cross-list posting, but this email is very important for us, and for you we hope. -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Array does not show its content, just number of items

by Jan Kurš

Hey, I usually inspect a lot with arrays and since recently, I don't see really an array content, just number of items, eg: #( #('a' 'b') #('b')) -> inspect an Array [2 items] an Array [1 item] Instead of: #( #('a' 'b') #('b')) This is -- for me -- super-annoying. do you think an original functionality can be returned back, or you have some serious reasons to have it like this?
