Hi, I would like to see a lean diagram tool included into Pharo-dev in the future. The diagram part should be generic but by default it may include UML visualization (we once had this in the extended OB in the old Pharo-devs). A good UML editor would really be helpfull. I've seen "smallUML","Mondrian" and others but mostly they visualize existing code instead of "interactively create" new stuff. I would like to see a tool similar to "eUML2" in Java which is able to synchronize code and diagrams automatically. (see http://www.soyatec.com/euml2/screenshots) I think of the following scenario: - you open Pharo and select diagram editor from the world menu - you select/create a package, for instance "MyApp" - this leads to the following packages: "MyApp-Core" -> code "MyApp-Tests" -> SUnit test code "MyApp-Help" -> help descriptions "MyApp-Diagram" -> here the diagram contents stored in classes - you click on "new class" and place a UML class in the diagram area. You name your class in the graphic for instance "Person" - you add a property "firstName" -> an IVar "firstName" is created - it allows you to easily create accessors (if you click "read only" only a getter is created) - you create another class "Account" and create a relationship "owner" by drawing an association line, the code is created - if you "manually" add an ivar to a class it will popup in the diagram too - ... With a few clicks you are able to find a nice design and you can use the diagrams to discuss with others. Maybe this could lead to a Graphical Editing Framework similar to Eclipse GEF http://www.eclipse.org/gef/ allowing you to provide own shapes and connections by adding custom shape/connection libraries. Attached is a first shot on the graphic part. File into a 1.2 image and select "Tools"->"DiagramEditor". This is just a test - maybe it is also possible to extend existing frameworks like Mondrian ... Anyone interested... Bye T. -- GMX DSL Doppel-Flat ab 19,99 Euro/mtl.!
