HI Offray,

I gave it a quick bash and come up with the following code. It's just a prototype and could be greatly simplified.

- MCVersionInfo ancestors for whatever reason returned empty array down the line (so its cut off at the end), but I didn't investigate the problem

- edge building and possibly ancestor retrieval could be simplified with builders; I think RTMondrian has methods for it but can't remember exactly (agilevisualization mentioned RTGraphBuilder but that has been removed to my knowledge)

~~~~~~~~~~~~~~~

mc := MCSmalltalkhubRepository allInstances detect: [ :m | m project = 'Roassal2' ].

root := mc versionInfoFromFileNamed: mc readableFileNames first.

family := Set new.

retriever := nil.

retriever := [ :child |

family add: child.

child ancestors do: [ :a | retriever value: a ]

].

retriever value: root.

obs := family asGroup.

v := RTView new.

es := RTEllipse new size: 15; color: Color blue; elementsOn: obs.

v addAll: es.

edges := RTEdge

buildEdgesFromObjects: obs

from: #yourself

toAll: #ancestors

using: (RTArrowedLine new withShorterDistanceAttachPoint; color: Color red)

scope: es.

v addAll: edges.

es @ RTDraggable.

es @ (RTLabelled new text: [ :m | m nameWithout: 'Roassal2' ]).

v @ RTDraggableView.

v @ RTZoomableView.

RTDominanceTreeLayout new

verticalGap: 30;

horizontalGap: 15;

on: es.

v open

~~~~~~~~~~~~~~~~

Cheers,

Peter

Hi,

On a closer detail, seems that [1] contains the starting point I'm looking for. I'll keep you posted and of course any other approach will be listened.

Hi all,

I had asked a similar question before with no much advances, but today I made a discovery that can improve the things a lot: how to export timeline data as structured JSON [1] (and of course this open the possibility to work with it on Pharo). Now I would like to graph the data as a tree with forks, merges and dates and authors of commits. I have seen chronia, but seems overkill for this feature (and is integrated with CVS only).

As usual, any pointer on how to get this going will be greatly appreciated and I will give feedback to the community on how to do it.

Cheers,

Offray
