Feature Request - Expressions for columns, layers, etc.

[pepsijon]

Is it possible to utilize expressions for setting the column, layer, etc?

[4xel]

yes, it should be in te current beta, merged in #91

[pepsijon]

Variables are working, but Expressions do not seem to be. Could you check it on your end, and if it works, send an example? I use Expressions in other modules and internal actions, and they work fine, it's just in the Arena module.

Can you provide an example of where it is working? I never used them before.
also: could you give an example of what you want to be able to do?

Example: 1+$(internal:custom_A_Layer)*10 That’s an expression I use on other buttons and it works fine. Or another example for specifying a location: concat($(this:page), '/', $(this:row), '/', $(this:column)) In the Arena module, if I put in the variable $(internal:custom_A_Layer) then it works, but if I use any type of expression, it doesn’t work.

Just like the above example. So I want the buttons to dynamically set the Layer and Clip based on 2 variables being added together (an expression). In the Companion documentation under Expressions if gives information and examples. Thanks! Jon

I asked the slack chat for an example on how to implement this: https://bitfocusio.slack.com/archives/CFG7HAN5N/p1726349188908029

If you can tell me which other module works like this I can try have a look

I don’t remember which external module I saw it in, but there are several internal Companion actions that use expressions. And the documentation refers to modules using expressions as well. Like internal: Surface: Set to page I use that with things like 1+$(internal:custom_A_Layer)*10

Also, not sure if this is an issue or not, but whenever putting a variable in, it turns Red. The variable does work though. But seems to only be this module where it turns red.

So I did find this yesterday in the Companion area:
bitfocus/companion#2345

Apparently whatever module I saw that in, the module author must have implemented the expression support themselves. Hopefully they will get this added to Companion, so that it is easily available to all modules without having to do extensive parsing in each module.

Expressions are available within Companion's internal features, but I am assuming they haven't made this easy yet for modules to support. :/
