I sent out an email to the STP PMC yesterday night:

Hi all,

STP has proven to be cutting edge in many ways regarding the Eclipse development process. In particular, we were amongst the first to adopt a Subversion repository.

The reason why we went for those repositories are varied. First, I think most of us acknowledged that CVS was not fitting the bill so much anymore. We were also increasingly using SVN at work, and had gone through the hurdles of mastering it.

Some time passed. git and mercurial came along and revolutionized quite a few things. Just look at github and how the commit rate of rails changed since they moved there (around the 5th minute on this video of the Rails commit history [0])

I opened a bug about the possibility to move to git [1], and a webmaster hinted that supporting git would be considered if a couple of top level projects were asking for it.

That’s why I’m asking you to please cast an informal vote for this move. Please consider also voting on [1].

Thanks,

Antoine

Do you want to see DVCS support at Eclipse ? Please consider writing to your PMC today.

This proved to be well hidden ; you can add your own links to the left bar of the wiki.eclipse.org website by adding them individually to the project metadata.

1. Log into portal.eclipse.org with your committer credentials
2. Go to your project, and click on “Maintain project meta-data”
3. Click to edit the “project left nav” property
4. Now you can enter your link information:
5. Just save it, and do it as often as needed.
6. Go to your wiki page and edit it
7. Add this to the page: {{#eclipseproject:your.project.id}}
   I prefer using a template for this though.

Not sure you followed the latest news about Intalio, Inc. We just rolled out a new website, and we are introducing a new project named Dogfood.

The Dogfood project is exactly what it looks like: we are going to line up and eat our own software until it makes us sick of it. And then we will have some more.

As part of the project, I am tasked to find a way to transform a spreadsheet with some clear conventions into a fully executable process.
Our BPMN model being EMF-based, I showed it to the team, and we feel it’s simple enough that we can generate the XML from the spreadsheet.

How do you generate a EMF-generated model those days ? You would fire up Eclipse, open the diagram editor and modify what you see on screen. Or you would open the default tree editor and make some changes.

Here, we are looking at a different story. Indeed we want to generate our model without Eclipse. And why not without Java.

My idea is to use the ActiveRecord way to generate a model by reading the ecore file(s). The bright part of the idea is that you can have ActiveRecord read the ecore files and load up the classes in memory. There is no actual generation. You change the ecore file, run again, everything is here.

My hope is to be able to do this:

p = new Pool
activity = new Activity
activity.name = "sample activity"
activity.graph = p
other_activty = new Activity
other_activity.graph = p
s = new SequenceEdge
s.source = activity
s.target = other_activity


Did someone think of doing something like that before ? Is there someone crazy enough to read ecore files and create the metamodel inline around ? Does someone know of a way to use ActiveRecords with something that isn’t a DB table ?
