Testing if script is executing inside of compound custom action

[cohler]

Is there some way to test programmatically inside of a ReaScript to see if that ReaScript is executing inside a compound custom action?

In other words, lets say I have:

Action 1 (lua script)
Action 2 (lua script)
Action 3 (lua script)

And then I create a compound custom action

BigAction which executes Action 1; Action 2; Action 3

Is there any lua code I can write inside of Action 1, 2 or 3 to test to see if they are being executed as part of BigAction or just by themselves?

When I run run reaper.get_action_context within those Action 1, 2, 3, it tells me that the context is Action 1, 2, 3 no matter what.

How can I find out if I am running inside of BigAction?

I'm no Lua expert, so I don't know about its scoping rules, but a global variable could possibly solve your problem.

No. Global variables only exist within each lua script while they are executing. They don't continue to exist from script to script.

This variable could be saved as ProjExtState at start of the custom action. This would be a one line custom script.


Your script will then check this value at init.

Yeah, that's the only solution I have come up with so far. Specifically, I created a separate action which I include in the group action as the first action, and it saves a semaphor to memory rather than disk using SetExtState and then the internal actions can check that semaphor using GetExtState.

But it seems like there should be a builtin REAPER capability for doing that don't you think?

I also asked this question some time ago, but unfortunately there doesn't seem to be an easy solution: Reascripts inside custom actions: Get custom action context and steps?.

Yup. Thanks for the reference. This should clearly be a fundamental capability.
