Rules and return codes

I also think local rule templates are a feature that users might want to use too. I’m sure there are plenty of people who would rather write a simple rule once then duplicate it for different sets of Items than copy/paste/edit and/or publishing a rule template to the marketplace.

Yeah - the only reason I never made any documentation is that it’s all supposed to change if the “new YAML” PR is ever merged.

event.raw? This also includes what is received, i.e. the plain Java event.

Right, which is why I’m surprised event.raw.payload is undefined. Still need to look into it.

I hope we somehow get some movement on those PRs too.

The result of the last line executed becomes the implicit return value. I’ve always thought that was weird, but it’s how it’s always worked since the Experimental Rules Engine was first introduced way back in OH 2.1 or 2.2 (I remember having a discussion with @ysc about ti when I first started experimenting with it).

Yes I remember it too - thanks for the mention btw, great discussion here.

It’s true that it’s easy to consider a condition script as the body of a function (after all you have parameters and you are expected to return something) so having return <something> statements would make sense but it turns out it’s not how it works.

Just FYI I have started working on the required changes.

The core PRs and the PR to make the event conversion independent of the wrapper are merged.
The PR for changing the wrapper behaviour and adding the directive is open: https://github.com/openhab/openhab-addons/pull/19443

This PR adds the return block to Blockly (and also adapts to the new event attributes).
