Covid-19 has also affected the Lumiera project as Ichthyo has had a major workload to bear over the past year in his professional occupation in the financial sector as a developer. Moreover he continues to devote time to other projectes such as his contribution to Yoshimi (soft synthesiser), building an acceptance test framework and a test suite for Yoshimi and a Blender artwork project. However, modest progress has also been seen in Lumiera.
Over the past years, we have invested time in the Timeline View, and last year was no exception.
We previously reported on a milestone in being able to send a command from the stage layer all the way down to the session (Ticket #1099). More development work in this area resulted in us in succeeding to respond in the session with a structured message to populate the UI with such things as tracks, nested tracks, clips and some other widgets (Ticket #1014). Consequently, the UI has taken its very first steps in being able to interact with a user. A user can now command something by making some gestures. We plan to extend our gesture feature so that editing actions: trim, roll, slide and shuffle are provided by a gesture.
The importance of a reliable and flexible history has been long noted as a key feature of Lumiera by developers.
Developers have realised that a thorough and robust history mechanism can be implemented by separating events and commands. A command is evoked by a user, which might produce one or more events. A command might also produce no event at all. A flexible history framework will be based on events not on commands. We are now in a position to be able to provide a tentative definition of events, which can be refined as required in the future. Such a definition will be the of a history framework.
