Are you looking for a way to integrate blockly inside Anvil or you want to program Anvil with blockly instead of python, in other words replace python with blockly?
The typical Anvil’s user is either a beginner programmer that wants to learn or an expert programmer that wants to be more productive. I haven’t seen anyone around that…
Both beginners and experts are here to produce apps.
I don’t know blockly, please correct me if I’m wrong, but I’m going to guess that replacing python with blockly is neither going to teach anyone programming skills nor make anyone more productive in creating apps. Sooo… can you please elaborate on what you are thinking about?
