[ann] jdt2famix - an open-source java importer project

by Tudor Girba

Hi, I would like to announce the jdt2famix project. This aims to be an open-source solution for importing Java projects into Moose: http://www.smalltalkhub.com/#!/~Moose/Jdt2Famix The project is based on: - JDT for raw parsing. This is implemented in Java. - JNIPort for delegating to Pharo the Java methods that visit the Java AST. Installation details can be found on the main project page. The current importing logic is rudimentary, but the first goal was to setup the whole ping-pong between Pharo and Java. This one works, and I am quite happy about that. You can take a look at the JdtImporterTest. CAVEATS: - Due to a problem in JNIPort, currently, this project only works in Moose 5.0. - Also, for now it works out of the box only for Mac OS X. - And, on top of that, it requires Java 1.6 for now (until we will get the Spur VM on 64 bits). There are still quite some challenges left, but once we get this going, we would also be able to use deep AST analysis live, and to do incremental model update when something changes on disk. Furthermore, if it scales, this would not be based on an intermediary MSE file anymore. I would like to ask for help in several directions: 1. Implement the full model import. This would require diving into JDT and implementing the corresponding mapping logic. I spent a few days on this. It is hairy, but it is not that impossible (only it has a ton of edge cases). This should be test driven, in that, for each case, we need to have a corresponding sample. 2. Fix JNIPort to work in Pharo 5. 3. Get the whole thing to work out of the box for Linux and Windows. 4. Check scalability. Please let me know your opinions, and let me know if you would like to participate. Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"

how to increase memory for the jvm through jniport?

by Tudor Girba

Hi, When using JNIPort I am getting a "java.lang.OutOfMemory: Java heap space". To go around this, I would need to provide more memory to the JVM. Essentially, I would like to provide the correspondent of a command line like: java -Xmx4000m How should I do this? Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"

Important problem due to syntax highlighting

by Alexandre Bergel

Hi! Here is a serious bug: Type (in a playground or code browser) the following: #(‘hello’) I get a violent #isNumberLiteralToken DNU on RBErrorToken Also, consider the following: The closing ) has the same color than the symbol. Which is not correct. It should have the same color than the opening ( Apparently these error do not occur in Pharo 5 https://github.com/moosetechnology/Moose/issues/1125 <https://github.com/moosetechnology/Moose/issues/1125> Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

RTEdge class "edge construction" deprecated

by Peter Uhnák

Hi, "edge construction" protocol of RTEdge is deprecated, but I don't see by what. RTEdgeBuilder perhaps? Thanks, Peter

interview on .Net Rocks! about Moose, humane assessment, Pharo and GT

by Tudor Girba

Hi, I had the pleasure of giving an interview for the .Net Rocks! podcast. It was quite fun and I managed to mention Moose, humane assessment, Pharo and GT in 45 minutes. It was not as smooth as a presentation but I still think it's a useful advertisement. Let me know what you think, and feel free to promote it further: https://dotnetrocks.com/default.aspx?showNum=1172 http://www.tudorgirba.com/blog/dotnetrocks-interview-moose-humane-assessmen… Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"

Text rotation in Roassal

by Alexandre Bergel

Hi! I am experiencing a weird behavior when rotating text: an extra space seems to have been inserted. For example the screenshot shows ‘J anu ary’. Anyone has seen this before? Any idea how to fix it? Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Roassal TRConstraint deprecation

by Peter Uhnák

Hi Alex, you've marked TRConstraint as obsolete, however not all behavior has been yet implemented in new RTConstraint. Namely methods from "public - resizing", "public - camera", and "public - aligning". Secondly I am not sure about the name of RTConstraint class>>child:parent: (Tudor also didn't like the name when he saw it. :)) I don't think the naming fits well into Roassal... maybe RTConstraint class>>on:backElement: ? Thanks, Peter

RTEdgeBuilder very strange behavior

by Peter Uhnák

Hi Alex, I've encountered a very strange behavior and I cannot tell what is going on. This is old RTEdge build* ~~~~~~~~~~~~~~~~~~~~~ | v es | v := RTView new. es := RTBox elementsOn: (1 to: 10). v addAll: es. es @ RTDraggable. RTEdge buildEdgesFromObjects: (1 to: 10) from: #yourself toAll: [:value | (Array with: value -1 with: value + 1 with: value + 2) ] inView: v. RTForceBasedLayout on: es. v addAnimation: (RTSpringLayoutStepping new view: v). v @ RTDraggableView. ^ v ~~~~~~~~~~~~~~~~~~~~~~~~ the layouting is almost instant, however if I use RTEdgeBuilder suddenly it is very slow ~~~~~~~~~~~~~~~~~~~~~~~~ | v es | v := RTView new. es := RTBox elementsOn: (1 to: 10). v addAll: es. es @ RTDraggable. RTEdgeBuilder new view: v; elements: es; connectToAll: [:value | (Array with: value -1 with: value + 1 with: value + 2) ]. RTForceBasedLayout on: es. v addAnimation: (RTSpringLayoutStepping new view: v). v @ RTDraggableView. ^ v ~~~~~~~~~~~~~~~~~~~~~~~~~~ the view still has the same number of elements and edges and the output looks identical, but with EdgeBuilder is it very slow. Profiler is showing me that with EdgeBuilder it spends a lot of time in attach points and with moving edges, which is strange. In either case it has no right to be so slow with 10 elements and 26 edges... Can you reproduce this behavior? Thanks, Peter

Glamour Magritte Example Broken

by Gareth Cox

Hi all I've just tried to use GLMAnnouncingCollection and found something odd. When you use it and its passed into a block (such as TableColumn computation:) it passes in the whole collection, not each item. Change the collection to OrderedCollection and it works as expected (except you lose the behaviour of GLMAnnouncingCollection). So, to find out how this is used I go to the examples provided, specifically "Magritte presentation". This has the following comment: "self new magritte openOn: GLMMagrittePersonExample sampleData" "GLMMagrittePersonExample sampleReset" "note, sampleData is aGLMAnnouncingCollection" This does not work as expected (or indeed how it used to). I've looked at this before and done work with Magritte using this example with Diego Lont and Stephan Eggermont. Its definitely become broken since the last time I looked at it. Can we confirm?
