Brendan Hansknecht (Jul 08 2022 at 22:31): Brendan Hansknecht (Jul 08 2022 at 22:31):When it comes to a host calling a closure, they get 3 parameters:
flags, closure data, and output.
Is my understanding accurate that:
flags is inputs,
closure data is captured variables,
and of course output is output.
Folkert de Vries (Jul 08 2022 at 22:32):the flags bit is arbitrary
Folkert de Vries (Jul 08 2022 at 22:32):in elm, your main function, in the most general case, takes some flags to get started
Folkert de Vries (Jul 08 2022 at 22:33):but if on your platform you want to have two initial arguments, you can (or should be able to, I guess this is untested)
Brendan Hansknecht (Jul 08 2022 at 22:38):So flags can be used as a input from the platform if wanted, but also can be used for other things?
Folkert de Vries (Jul 08 2022 at 22:41):I guess? the idea here is that the platform can inject some data
Folkert de Vries (Jul 08 2022 at 22:42):that data can come form the platform itself, or might be produced by other roc functions
Brendan Hansknecht (Jul 08 2022 at 22:47):ok. makes sense
