Alexandre, Could you please run this: ~~~~~~~~~ "Adapted from: https://vimeo.com/116886609" | view timeline | "Loading package for working with fossil" "Integration with external tools" Gofer new smalltalkhubUser: 'Offray' project: 'Grafoscopio'; package: 'Grafoscopio-ExternalTools'; load. "Extracting data" timeline := FossilTimeline new. timeline importFromUrl: 'http://mutabit.com/deltas/repos.fossil/piamed/libro/doc/tip/Libro/timeline-b...'. "Visualization" view := RTMondrian new. view nodes: timeline commits. view edges connectFrom: [#parents first]. view layout tree. view. "(timeline commits at: 1) parents first" ~~~~~~~~~ At the end you will get a set of squares visualized like this ones: ^Up Graphic 1: Trying to understand edges. These squares are representations of FossilCommits objects imported from a Json file, and the "connectFrom: [#parents first]" is the line I'm having problems with. "#parents first" is the message I send to each node to know its parents in that very collection of commits, so I imagined that if I put that as the block argument for "connectFrom" I would get a nice tree, similar to the graphic 2 below. I don't get what's happening here or what I'm missing. ^ Up Graphic 2: A nicely drawn mondrian tree layout for RTLayout. Any help on how to get tree like visualizations for this Fossil objects would be greatly appreciated. Thanks, Offray Ps: Something was happening with ws.stfx.eu this morning at 7:00 (GMT -5) and trying to publish a workspace gives a 500 error. On 16/06/15 16:08, Alexandre Bergel wrote:

Can you make the image accessible for me? I can then have a closer look at it.

Hi all. Is me again :),
I have being fighting all this morning trying to bet a better understanding of edge connections and tree layouts. I'm making some progress, but still I don't grasp it. At [1] you can find my starting example. So far, so good, so I created my own variation for my own data at [2]. My main issue is the #connectFrom message argument. If you uncomment the last line of [1] you will see that sending the #superclass message gives me an object that is of the same kind that the ones have been added to the view previously and I imagine that the reason they can be connected in a tree. With the example at [2] the message [#parents first] gives me a fossil commit object, but if I ran the code, the nodes are unconnected. What I'm missing?

Hi Peter,
Thanks for your quick answer. I was pretty curious about trying to implement some of this ideas, but only until today I had the proper time to do it. I ran your code and now I'm trying to translate the ideas on it to my problem: Drawing a tree for the story of a fossil repository.
First, using the procedure at [1] I was able to export a fossil commit repo history as Json and by running the script at [2] I was able to get a small set of dots, which represent dictionaries with all commit data, including ancestors for each node, like the attached screenshot shows. In the video at [3] at 1:06 min, seems that lays the key for my visualization, but for that I need to create a fossil commit object that can understand the #ancestor message. Because I already have them as dictionaries thanks to NeoJson, seems that I'm really close to get the visualization I'm looking for. I hope to work on it this morning and return to the list with data visualizations or more questions.

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' ].

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.

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.
