Oberon (programming language) Wirth's way of inheritance reflecting the viewpoint of the parent site. Oberon was developed as part of the implementation of the Oberon operating system at ETH Zurich in Switzerland. The name is from the moon of Uranus, Oberon. Oberon is still maintained by Wirth and the latest revision is dated August 4, 2018. Oberon is designed with a motto attributed to Albert Einstein in mind: “Make things as simple as possible, but not simpler.” The principal guideline was to concentrate on features that are basic and essential and to omit ephemeral issues. Another factor was recognition of the growth of
Oberon (operating system) to as Linz-Oberon) and "Oberon System 3" (or S3, sometimes also called ETH-Oberon or Spirit of Oberon), enhanced the basic interface with different but incompatible implementations for buttons, drop down menus, and other active elements. V4 used for that purpose a dedicated control character embedded in normal text in contrast to System 3, which extended the kernel by introducing persistent objects. Both extensions include a large set of user interface elements. Mastering the Oberon user interface, both the purely textual and also the so called Gadgets System (under S3), is absolutely non-trivial. Therefore it is recommended to proceed after a
