Why AnnotationInstance type is container?
by Pavel Krivanek 31 Jul '18

31 Jul '18

Hi, In old FAMIX, the FAMIXAnnotationInstance defines two containers: - annotatedEntity - annotationType The annotatedEntity is used for belongsTo, but I would like to know why annotationType was defined as container too. Does it has some reason? Cheers, -- Pavel

Moose Java AST?
by Peter Uhnák 31 Jul '18

31 Jul '18

Hi, is there a Java AST parser in Pharo? I imagine that jdt2famix must have something inside, but as far as I understand, it just extracts some information from the source code and throws the AST away. Thanks, Peter

How to visualize any SVG
by Hernán Morales Durand 29 Jul '18

29 Jul '18

Hi, Here I am trying to visualize a SVG figure generic enough to cover many other SVG figures. Currently I use the SVG logo: https://upload.wikimedia.org/wikipedia/commons/0/02/SVG_logo.svg which contains SVG paths, rect, circles and polygons. First I tried to parse with the Athens-SVG included in Pharo 6.1: AthensSceneView new scene: (AthensSVGConverter fromURL: 'https://upload.wikimedia.org/wikipedia/commons/0/02/SVG_logo.svg'); openInWindow but fails with: "Error: cannot resolve url: http://www.w3.org/Graphics/SVG/" So I quickly switched to Roassal SVG. The SVG examples does not cover for example specified colors but they are replaced with Color random. Also using this expression it seems there is no support for "circle" type. RTSVGEntity withAllSubclasses collect: [ : s | s hasSubclasses not ifTrue: [ s new type ] ] as: Set) reject: #isNil with that in mind I tried to parse the SVG logo with the following terrible script which only support paths but can read named or hex colors | tree view | view := RTView new. tree := XMLDOMParser parseURL: 'https://upload.wikimedia.org/wikipedia/commons/0/02/SVG_logo.svg'. view := RTView new. (tree allElementsSelect: [ :e | e isElementNamed: #path ]) elementsDo: [ : node | | elem color colorAtt | color := (node includesAttribute: 'fill') ifTrue: [ Color fromHexString: (((colorAtt := node attributeAt: 'fill') beginsWith: '#') ifTrue: [ colorAtt allButFirst ] ifFalse: [ colorAtt ]) ] ifFalse: [ Color random ]. elem := (RTSVGPath new path: (node attributeAt: 'd'); fillColor: color; scale: 1) element model: (node attributeAt: 'title'). elem @ RTPopup. view add: elem ]. view inspect However adding support for circle, rect, polygon, etc. is becoming too complicated this way :) Is there some other recommended way how to approach this? Cheers, Hernán

Roassal2 in Pharo 6.1 (Win) 137 tests fails
by Hernán Morales Durand 08 Jul '18

08 Jul '18

In a clean Pharo 6.1 (Windows 8) I loaded Roassal2 with the following spec in a baseline: spec project: 'Roassal2' with: [ spec className: #ConfigurationOfRoassal2; versionString: #stable; repository: 'http://www.smalltalkhub.com/mc/ObjectProfile/Roassal2' ]. But many Trachel tests fails because of "External module not found" error (Screenshots attached). May be Roassal2 is broken on Windows? I tried loading Roassal2 from the Catalog browser and the same 137 tests fails. Any idea what could be missing? Cheers, Hernán

[ann] gt documenter
by Tudor Girba 02 Jul '18

02 Jul '18

Hi, We are happy to announce a new leap of GToolkit Documenter, the tool for manipulating live documents directly in the development environment: https://github.com/feenkcom/gtoolkit-documenter Documenter is part of the second generation GToolkit project, it is based on Bloc and works with the latest Pillar. It is mainly developed by Juraj Kubelka. Attached you can see a preview of how documents look like: At its core it offers a live editor for manipulating Pillar documents. The interaction happens seamlessly directly in the text editor, and it can be combined with different types of previews to serve several classes of use cases: • code documentation • tutorials • interactive data notebook Code documentation ---- Documenter complements the GToolkit Examples engine to redefine code documentation. When practicing example-driven development, examples get written as part of the typical development. Once examples exist, they can be quickly put together in a document to form documentation. For example, the linked picture shows the comment of a class containing a visual explanation: https://twitter.com/feenkcom/status/973899862482866176 You can see a live example of documentation by inspecting the following snippet: GtDocumenter editorForText: BrToggleExamples comment. Tutorials: ---- Documenter offers a new experience of writing tutorials for Pharo by enabling the creation and embedding of Epicea change sessions directly in the document. For example, take a look at the following animation: https://twitter.com/feenkcom/status/999975333972541440 The document shows a method on top, and a change preview at the bottom showing both the code and the associated diff to the state from the image. Applying the change updates both the change view (no more diff), and method preview. This speeds up significantly the process of going through a tutorial. Furthermore, given that now the document shows the diff to the current image, the reader can safely explore alternative scenario and come back to the tutorial at any time without losing the overview. The size of the preview can also be adjusted live: https://twitter.com/feenkcom/status/1001152789874167808 https://twitter.com/feenkcom/status/1001407762285375490 You can see a live tutorial by inspecting: IceRepository repositoriesLocation / 'feenkcom'/ 'gtoolkit-examples' / 'doc' / 'tutorial' / 'examples-tutorial.pillar’. Interactive data notebook: ---- A Documenter document can also be used as an interactive notebook. Internally it essentially acts as a playground: • it supports defining variables in code snippets, and • the execution of code shows an embedded inspector. For example: https://twitter.com/feenkcom/status/996310432225820672 https://twitter.com/feenkcom/status/1002851190475026432 An example, can be seen by inspecting: IceRepository repositoriesLocation / 'feenkcom'/ 'gtoolkit' / 'doc' / 'gtoolkit' / 'gtoolkit.pillar'. As always, please do let us know what you think. Enjoy, The feenk team -- www.tudorgirba.com www.feenk.com "If you can't say why something is relevant, it probably isn't."

Beginner questions re. Moose analysis of C++ source code
by smallglt 02 Jul '18

02 Jul '18

I'm totally new to Moose (and effectively new to Smalltalk) and need a pointer or two on analyzing an old application that was developed in Visual C++ 2006. I have the complete sources, including the Visual Studio project files, resource files, etc. I've already got Pharo and Moose installed on my Windows system and have been able to get the Moose playground to run, but that's about it. So far I don't know how to get Moose to do anything else. My initial goal is just to get this source code "loaded" into Moose. I've seen references to VerveineC-Cpp and Famix-C but no explanation of how to use either one. I haven't had an opportunity yet to try VerveineC-Cpp on Windows 10 at my office. On my personal Mac (i.e. not on the office system where I actually need to do this work) I installed Eclipse Oxygen and tried to follow the very limited directions to install VerveineC-Cpp, but Eclipse complains about the build path. Maybe Eclipse Mars is needed instead of Jupiter? It also looks like I might need to use the old, deprecated Java V1.7 for MacOS, instead of a current version of Java? (Hopefully I won't need an older version of MacOS. I'm running Sierra V10.12 with all updates as of this writing.) Maybe that would all be more straightforward somehow on Windows? (I also have Linux at work, if that would be any easier.) As for Famix-C, I see that it appears to be "built in" to the Moose environment that I installed at work and at home. But I don't know how to make it do anything. I greatly appreciate any hints or suggestions. I'm very eager to begin using Moose and to (re)learn Smalltalk, especially in the Pharo environment which looks really fascinating. (Trivia: Back in the early 1990's or thereabouts, while taking a graduate course in operating system design, I learned enough Smalltalk to get me started on writing an emulator for the simple machine specification the professor gave us. But a single academic quarter, roughly three months, just wasn't enough time to both learn a totally new, object oriented programming paradigm /and/ use it to complete such a program, while also holding down a full time job and leading a regular life. :-) But I did write a good paper explaining my ideas and how far I'd actually been able to carry them. The professor was understanding, liked my concept, and I managed to get a B+ grade for the course.) -- Sent from: http://forum.world.st/Moose-f1310756.html
