Roassal DNU getting the element from an RTArrowedLine
by Johan Fabry 10 Mar '16

10 Mar '16

Hola, in part of the code of LRP I work with arrows, and I need to get the shape, but this triggers a DNU. I guess I need to set something on the arrow before I can get the element, or get it via another route. What should I do? Relevant code below: arrow := RTArrowedLine new color: trans color; edgeFrom: efrom to: eto; withOffsetIfMultiple. element := arrow element. Gives me: RTElement(Object)>>doesNotUnderstand: #to RTShorterDistanceWithOffsetAttachPoint(RTAbstractShorterDistanceAttachPoint)>>basicStartingPointOf: RTShorterDistanceWithOffsetAttachPoint>>basicStartingPointOf: RTShorterDistanceWithOffsetAttachPoint(RTAttachPoint)>>startingPointOf: RTLine(RTAbstractLine)>>updateFor:trachelShape: RTLine(RTShape)>>trachelShapeFor: RTArrowedLine>>trachelShapeFor: RTElement(RTShapedObject)>>addShape: RTArrowedLine(RTShape)>>element LRPProgramVisualization>>buildTransition:withElements:forView: ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD and RyCh labs - Computer Science Department (DCC) - University of Chile

Call for action for Roassal
by Alexandre Bergel 10 Mar '16

10 Mar '16

Dear community, As you may have seen, Roassal has entered a stabilization phase. The book AgileVisualization.com will soon be released. After its release, Roassal will go over a new development phase. In order to prepare it, I am asking this question: What are the 3 aspects you would like to see improved in Roassal? You can answer publicly or by sending private messages. Kind regards, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Roassal RTArrowedLine width: bug
by Johan Fabry 10 Mar '16

10 Mar '16

Hola, there is a bug in RTArrowedLine: the width: message (defined in the RTAbstractArrowedLine superclass) does not set the width of the head. Could something like the code below be added? This code solves the problem for me. RTArrowedLine>>width: aNumber super width: aNumber. self head width: aNumber. and I imagine something similar should be done with RTDoubleArrowedLine (but I have no experience with that guy). ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD and RyCh labs - Computer Science Department (DCC) - University of Chile

Postdoc in Chile
by Alexandre Bergel 10 Mar '16

10 Mar '16

Hi! We have an opportunity for doing a postdoc in Chile, in the field of software engineering and/or data visualization. I could provide a lengthy description about living in Chile, and its fantastic food, latin atmosphere, and gorgeous nature. But I will surely be far from the truth. If you want to know more about this possibility, get in touch!

See the 'attach point' protocol of RTAbstractLine. Some of them also automatically add extra space if there are multiple lines between the same elements. As for bezier and multiline edges, their curvature isn't currently handled properly, but it's in my todo list (I'll work on this probably during the weekend). I'm sure it can be presented in more revealing way, but it's too late for me today (or is it too early?). You can play with it (drag the elements to see how it behaves). ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |v attachOptions es e offset| v := RTView new. attachOptions := RTAbstractLine selectors select: [ :each | each beginsWith: #with ]. offset := 0 @ 0. attachOptions do: [ :each | es := RTBox new borderColor: Color black; size: 50; elementsOn: #(a b). each = #withContinuousCircleAttachPoint ifTrue: [ es := RTEllipse new borderColor: Color black; size: 50; elementsOn: #(a b). ]. es translateBy: offset. es @ RTDraggable. offset := offset + (0 @ 100). v addAll: es. es second translateBy: 300 @ 25. e := RTArrowedLine new color: Color black; perform: each; edgeFrom: es first to: es second. e model: each. v add: e. e @ (RTLabelled new color: Color black). ]. v ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ > > ___\|/___ > | | > \| |/ > --| |-- > /| |\ > |_________| > /|\ > > bezier edges should always leave at a 90deg angle: > ____|____ > | | > | | > --| |-- > | | > |_________| > | > > optionally, starting at the corners could also be nice: > > \_________/ > | | > | | > | | > | | > |_________| > / \ > > and in such a case bezier edges should leave at 135deg to each side. > > by default the edge should find the nearest connection point, but i'd like > to > configure a list of allowed points. > > finally, multiple edges in the same general direction should either leave > at > the same point, pick the nearest side that doesn't have an edge already. > or spaced evenly along the same side if all available sides have edges > already. > > the list of allowed connection points would have 12 options: > the middle of 4 sides, 4 corners, and 4 sides as a whole when multiple > edges > should be spaced evenly. > > greetings, martin. > > -- > eKita - the online platform for your entire academic > life > -- > chief engineer > eKita.co > pike programmer pike.lysator.liu.se caudium.net > societyserver.org > secretary > beijinglug.org > mentor > fossasia.org > foresight developer foresightlinux.org > realss.com > unix sysadmin > Martin Bähr working in china > http://societyserver.org/mbaehr/ > >

Roassal not working? (at least on Linux)

Hi, When I download the latest and greatest moose image and the latest stable VM, I get an errorKeyNotFound: exception when evaluating: RTGrapher new. For more details see the stacktrace below.

issue with spotter
by Alexandre Bergel 09 Mar '16

09 Mar '16

Hi! When I activate spotter, and _quickly_ type something, “roassal” for example, and press the down arrow, the selection jumps to the top. I guess this happens when spotter is retrieving data from the system which somehow move the selection to the top most item. This is particularly annoying. Am I the only one to experience this? Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.
