Roassal Easel examples interface

by Ben Coman

Just a few thoughts about how the Roassal Easel [Examples] are presented. Some text describing the meaning of the blue and pink grouping boxes would be useful - but to hazard a guess blue is the replicated Mondrian functionality and pink is the new Roassal functionality ? The ZoomIn and ZoomOut buttons don't work with either the [Examples] of [Info] displayed - which is fair enough, but there is no feedback to indicate the buttons will have no effect. This is quite nit-picking so perhaps can be ignored. Once any particular example is clicked, there is nothing that displays what the current example is - so if (like me) you forget which it was two seconds after you click it, you end up a bit lost. It would be nice to have something that identifies the current example. Example>interaction>leftAndRightClick - fails Example>interaction>clickAndMove - the element ends up about 150 pixels below the click. It should either centre or align a corner with the click. Example>colors>normalizer - it is not clear what the purpose of this is, especially under a colors section - it is just an empty black box that is moved around.

migrating mondrian to roassal - Menus

by Ben Coman

just documenting another migration.... this in Mondrian... view interaction menuItems add: 'Browse class' -> [:a2 | a2 browse ]. view interaction registerMenu. appears to become this in Roassal... view interaction item: 'Browse class' action: #browse. How do you get a context menu on the background? btw, I see that ROEaselMorphic>>populateMenuOn: calls #zoomInButtonOn: which calls #addMenu:callBack: Does #addMenu:callBack always draw the item in a box? Can you get multiple items in one box? From an outside perspective if there can be only one item per box then #addButton:callBack would seem a more appropriate name.

reflections upon MooseChef withoutSelfLoops and scoping

by Nicolas Anquetil

Anybody can submit an opinion to the following issue: MooseChef allows to express a query such as: aClass queryOutgoingInvocations aMethod queryOutgoingReferences that will return all methods invoked from 'aClass' for the first query and all classes referenced by 'aMethod' in the second query Then you can constraint the scope of the result, for example to say that you are interested by the package containing the referenced classes aMethod queryOutgoingReferences atPackageScope You can also down scope the result, for example to say you want all the methods of the class referenced: aMethod queryOutgoingReferences atMethodScope Finally, there is something to say you are not interested in relation that loop back to the original object queried aClass queryOutgoingInvocations withoutSelfLoops will return all classes that own methods invoked from 'aClass' except 'aClass' itself (that would be a selfLoop) one sees on this example that withoutSelfLoops involves some scoping: queryOutgoingInvocations will return a collection of methods, but the query was sent to a class. So when we say withoutSelfLoop, we actually mean all methods that don't belong to the class to which the query was sent. This is equivalent to: aClass queryOutgoingInvocations atClassScope withoutSelfLoops Up to now, the semantic is rather Ok, but when you use hidden down scoping, it starts to be less clear: aMethod queryOutgoingReference withoutSelfLoops will return all classes referenced in 'aMethod' taken at methodScope and removing self loop. In the end, the result will ignore references to the class owning 'aMethod'. What do you think? There is some logic in the semantic, but it is not so intuitive. Looking at the query, I cannot convince me that this is the result that one would expect. Should we change the semantic? To what? (keep up-scoping and forbid implicit down-scoping? forbid all implicit re-scoping?) nicolas PS: This may look like a rather theoretical question, but I actually have a bug partly related to that and I need to know how to solve it

migrating mondrian to roassal - MOLineShape>>frompositions & view domain

by Ben Coman

I have just downloaded Moose47 and am starting to migrate my app from Mondrian to Roassal. For the code below where 'a mondrian' /becomes/ 'a roassal' ... At "#1" I get MNU ROLine>>fromPositions For now I worked around this by deleting #fromPositions: and #toPositions: but how do I get similar functionality to manage where the endpoints ? I did find in "attachPoint := ROShorterDistanceAttachPoint instance" in ROLine>>initialize but it would be good to get an idea of the overall architecture for this. At "#2" I get MNU ROMondrianViewBuilder>>domain - where #domain returns an OrderedList of all the model entities, of which I ask each for all its relationship links to other model entities to define the edges. For now I worked around this by factoring "EpcimRoot withAllSubclasses" out to a temporary variable, but I am wondering how in future to access the model entities of the graph. I did find "#elementsWithModelDo:" in ROMondrianViewBuilder>>rawEdgesFrom:to: but not sure whether that is a public/private method. ---------------------- a mondrian title: 'Class Definition - Full Model' ; painting: [ :view :selection | view shape label. view interaction popupText: [ : element | element class comment ]. view nodes: (EpcimRoot withAllSubclasses). view edgesFrom: #superclass. (view shape line) "#1: /was/ a MOStraightLine /becomes/ a ROLine " color: Color lightBrown. fromPositions: #(#center); toPositions: #(#center). view edges: view domain "#2: view /was/ a MOViewRenderer /becomes/ a ROMondrianViewBuilder" from: #yourself toAll: [ :x | x relations collect: [ :z | z key ] ]. view horizontalTreeLayout . ]

Issue 701 in moose-technology: Cut and Paste do not update a Glamour Port

by moose-technology＠googlecode.com

Status: New Owner: ---- CC: tudor.gi...(a)gmail.com Labels: Type-Defect Priority-Medium Component-Glamour New issue 701 by alexandr...(a)gmail.com: Cut and Paste do not update a Glamour Port http://code.google.com/p/moose-technology/issues/detail?id=701 Email snippets: Regarding copy paste, indeed it seems that pasting a text does not update the port. Please open a ticket. ------- I found another strange behavior, likely to be a bug. Try: -=-=-=-=-=-= | browser | browser := GLMFinder new. browser text act: [:prez :v | prez text inspect ] on: $i entitled: 'Inspect'. browser openOn: 'hello world' -=-=-=-=-=-= If you type something and press cmd-i then you open an inspector on what you have typed. Now, do a cut and paste in the textpane, and press cmd-i. You have an inspector on 'hello world', no matter what you have cut&pasted.

scaling moose

by Tudor Girba

Hi, A topic that was raised recently is the scalability issue of Moose. Indeed, it would be great to have again some traction in this direction. I think there are a couple of possibilities in this area: - Gemstone. This is the straightforward idea and it would probably match quite well the FAMIX object-oriented model. The realization might not be that easy because we would need to go through all the details of the language independence. Also, we would need a remote UI, or at least a bridge for Glamour. Perhaps the Seaside interface of Glamour, or another Seaside-based one, would be a good direction. - Graph DBs. http://neo4j.org/ would be an interesting target here. I have no experience in this area, but I would be very interested in collaborating with someone on this. - Relational DBs. I know that Marco D'Ambros worked on a solution to map FAMIX meta-descriptions to Glorp in VW. And it seemed to work. I think Alberto Bacchelli is or has used it. - Fuel. Loading with Fuel is about one order of magnitude faster than loading plain MSE: for example for ArgoUML 0.32 I got 108s for the MSE, and 17s for the Fuel based MSE information. So, having the Fuel export next to the MSE file can be a significant improvement. However, this solution only works when you have computations that treat one model at a time (so, it's not so nice if you have to switch between models all the time). I attached a simple script to analyze the difference between plain MSE loading and Fuel load variations. - Filtered loading. This solution works well when you have the full model, but you do not need all of it. FMMetaRepositoryFilter offers the infrastructure for a filtered loading at the level of FAME: if you want to load a sub part of your model, you construct a sub-meta-model and then let Fame do the rest. This kind of works, but it is only available at the moment in code (look at the tests). We need to move to the next step of integrating this solution and replace the MooseImportingContext and possibly offer a UI as well. If you want to pick up on any of these topics, let's open a separate thread and see what we can do. Cheers, Doru -- www.tudorgirba.com "We can create beautiful models in a vacuum. But, to get them effective we have to deal with the inconvenience of reality."
