Scripts Folder?

[Steve40 (Steve)]

Evening, all!

In openHab 1.x there was a scripts folder where you could place bits of code for reuse, kinda like a function/subroutine, except (if I recall correctly) it was relatively useless since you couldn’t pass variables to the scripts.

Thanks!

It still works the same.

Depends on what you are trying to accomplish.

Reusable Functions: A simple lambda example with copious notes

Major Edit: Rewrote with the cleaner OH 2.3 syntax. The example lambda on the OH 1 wiki is overly complex and as written will not work in OH 2. This quick example will show a super simple lambda example with copious notes. Here is the code without comments. It takes in an Item, logs it’s state and returns a slightly modified version of the String logged. val log= [ GenericItem s | logInfo("lambda", s.state.toString) s.state.toString + " logged" ] rule "Call Lambda" when // some t…

That’s exactly the info that I needed! Thanks!
