Hi, I published some very simple utility code on
https://github.com/astares/Pharo-YUML to easily generate links for YUML. Use the load expression given on the project site or load "YUML" from catalog. Allows you to get a class hierarchy image of an existing Pharo class. It could help to include simple class hierarchy pictures into your (markdown or other) documentation. Example: YUMLGenerator open: String opens a browser to let YUML generate the class hierarchy of String. The clip the URL to your docu as image, for instance in markdown write:  If you need the URL directly then use YUMLGenerator new generateHierarchyFor: String Docu is in https://github.com/astares/Pharo-YUML/blob/master/README.md including an example picture. Maybe it is useful for others too. Thx T.
