Hi, Currently GSBerlin is the only build that fails from Jenkins. The problem is in ConfigurationOfVidi>>baseline031: which tries to load the Roassal2 group from ConfigurationOfGlamour. Removing the line 'loads: #('Roassal2');' should fix the build. Cheers, Andrei

Indentation Sensitive Languages in PetitParser

by Jan Kurš

Hi All, I have pushed a new version for indentation sensitivity into the PetitParser. If I am not mistaken, with the new changes, you can parse languages such as Python, F#, Haskell, YAML or Markdown. There are proof of concept implementations in the PetitParser repository. YAML and Markdwon are almost complete, for Python only the indentation-sensitive rules. There is a small introduction to the indentation parsing with PetitParser ( http://scg.unibe.ch/research/indentParsing), let me know, if you are missing something or if you want to know something more. There are also many examples of the indentation sensitive grammars in the repository. If you wonder about performance, the indentation sensitive grammar is approximately five times slower, because the position and an extra indentation stack is remembered instead of the simple position. If you don't use indentation, there is no slowdown. I am working on improvements, any ideas are welcome :) If you don't like new changes, you can still stable version (ConfigurationOfPetitParser loadStable) or version 1.11. Regards, Jan

Tagcloud around avatar part 2: Advances, questions and suggestions

by Offray Vladimir Luna Cárdenas

Hi, Following the advice of Peter Uhnák on tag clouds and avatars I made some progress on my intended visualization. If you run the code at [1] you will get something similar to [2] (the difference is that screenshot is for code inside a grafoscopio document instead of a simple playground). [1] http://ws.stfx.eu/9G5PEGYFL1MW [2] http://mutabit.com/deltas/repos.fossil/datapolis/doc/tip/Figures/personal-t… I will prioritize working on scrapping and cleaning the data, leaving the position of the avatar to the end (hopefully Alexandre will read this and in his attempt to make Roassal the best visualization engine in the universe and its users happier, he will implement my suggestion at the end). So in my attempt to clean the data I'm trying to process originalText (look at [1]) to split it to single words. For that I start copying that text and replacing any occurrence of punctuation characters and parenthesis by spaces and then applying #splitOn: ' ' to the new string. I made this by the chunk of code at [3], but seems inelegant and trying to use cascades and ending in #yourself didn't make the trick. =[3]========================== cookedText1 := originalText. cookedText1 := cookedText1 copyReplaceAll: ',' with: ' '. cookedText1 := cookedText1 copyReplaceAll: ';' with: ' '. cookedText1 := cookedText1 copyReplaceAll: '.' with: ' '. cookedText1 := cookedText1 copyReplaceAll: ':' with: ' '. cookedText1 := cookedText1 copyReplaceAll: ')' with: ' '. cookedText1 := cookedText1 copyReplaceAll: '(' with: ' '. ============================== So here come my questions: a) There is any form to replace code at [3] by a more elegant Smalltalk-ish way so I can have only words no matter if they are separated by spaces, punctuation marks of starting/ending with parenthesis? b) Why some uninteresting words like the Spanish 'La' or 'Se' are still getting their way in the final visualization even if I try to evade them with the code at [4] =[4]========================== (cookedText1 splitOn: ' ') do: [:word | ((word size > 1) & (uninterestingWords includes: word asLowercase) not) ifTrue: [cookedText2 := cookedText2, word, ' ']]. ============================== And my suggestion: Please consider making tag clouds with variable layouts and forms. Python has something similar with [5] [5] http://sebastianraschka.com/Articles/2014_twitter_wordcloud.html I will be waiting for your suggestions and thanks for keeping Pharo/Moose awesome! Cheers, Offray

3rd IEEE Working Conference on Software Visualization

by Alexandre Bergel

Dear all, Many of you have an interest in software visualization. Which is why this call for papers may be relevant for you. Kind regards, Alexandre ==== Call for Papers ==== VISSOFT 2015: 3rd IEEE Working Conference on Software Visualization September 27 - September 28, 2015, Bremen, Germany http://vissoft.info Software visualization is a broad research area encompassing concepts, methods, tools, and techniques that assist in a range of software engineering and software development activities. Covered aspects include the development and evaluation of approaches for visually analyzing software and software systems, including their structure, execution behavior, and evolution. The VISSOFT IEEE Working Conference on Software Visualization continues the history of the ACM SOFTVIS Symposium on Software Visualization and the IEEE VISSOFT International Workshop on Visualizing Software for Understanding and Analysis. The conference focuses on visualization techniques that target aspects of software maintenance and evolution, program comprehension, reverse engineering, and reengineering, i.e., how visualization helps professionals to understand, analyze, test and evolve software. We aim to gather tool developers, experts, users, and researchers from software engineering, information visualization, computer graphics, and human-computer interaction to discuss theoretical foundations, algorithms, techniques, tools, and applications related to software visualization. We seek technical papers, empirical studies, applications, or case studies and provide a platform for presenting novel research ideas and tools. Topics of interest include, but are not limited to: * Innovative visualization and visual analytics techniques for software engineering data, such as, - source code - static and dynamic dependencies - software evolution and repositories - software documentation - web services - protocol, log, and performance data - parallel techniques - database schemes - software security and privacy issues - workflow and business processes * Visualization to support program comprehension, software testing, and debugging * Interaction techniques and algorithms for software visualization * Visualization-based techniques in computer science and software engineering education * Integration of software visualization tools and development environments * Empirical evaluation of software visualization * Industrial experience on using software visualization Papers are solicited that present original, unpublished research results and will be rigorously reviewed by an international program committee. In addition to technical papers, VISSOFT features a New Ideas or Emerging Results (NIER) track and a Tool track related to the same list of topics suggested above. All accepted submissions will appear in the conference proceedings and the IEEE Digital Library. -== Technical papers ==- These contributions describe in-depth mature research results in the above-mentioned areas of interest. The submission of a video (up to 5 minutes in length) to accompany the paper is highly encouraged to show interaction possibilities. Authors who wish to submit such video should provide a URL to the video. Technical papers have to be maximum 10 pages long (including bibliography and annexes). Abstract submission date: April 27, 2015 Full paper submission date: May 4, 2015 Author response period: June 8 - 12, 2015 Notification: June 18, 2015 Artifacts: Traditionally, technical research papers are published without including any artifacts (such as tools, data, models, videos, etc.), even though the artifacts may serve as crucial and detailed evidence for the quality of the results that the associated paper offers. Following the effort initiated at ESEC/FSE’11, authors of accepted technical papers at VISSOFT 2015 can have their artifacts evaluated by the program committee. Positively evaluated artifacts will be reflected in the paper publication and presentation. More information about the artifacts may be found on http://www.artifact-eval.org .

Adding elements to GLMRoassal2Presentation

by Pierre CHANSON

Hi all, I realized that currently, it is not possible to inspect elements in the GLMRosassal2 presentation when they are created, as it works only on elements created at the initialization in: GLMRoassal2Presentation>>renderOn: I think the new elements added to the RTView should be inspectable in the presentation. A possible solution would be to GLMRoassal2Presentation to observe the RTView and when notified of creation of a new element, add the interaction to the new element ? --------------------------------------------------------------- v := RTView new. x:=0. v add: ((RTBox new size: 40) elementOn: x). v elements when: TRMouseRightClick do: [ | b | b := ((RTBox new size: 40) elementOn: x). v add: b. b translateBy: (x := x + 50)@0. v signalUpdate ]. v. ---------------------------------------------------------------------- Pierre
