Hello everyone!
For some time now, it is possible to assign a name to terminals in the element files. A unique UUID is automatically added in the background. If such a component is then inserted into a schematic and provided with connections, the UUIDs of the terminals are already used in the qet file to identify the connection.
At some point in the future, when the developers have (a lot of) time for the project again, the "UUID" and "Name" information will be used to automatically generate cable plans and wiring instructions.
As a "programming exercise", I looked in the source code for a way to include the names of the terminals in the connection line in the schematic file and actually found what I was looking for!
However, there is one "difficulty":
What name may automatically be used if the creator of the element has not assigned any names?
I made it easy for myself here and also saved the UUID of the connection for the name.
Here is the resulting diff file:
