# arrow

I've got some small programs embedded into my app which needs to be serialized and generated. Also needs to have some basic primitives and introspection abilities if possible - I've tinkered up something which kinda works, but I'm wondering if arrow has something along these lines?

Kinda reminds me of https://serranofp.com/inikio/ maybe

I think you can serialize coroutines btw. It needs an external library, but it's possible.

I'd prefer the serialized code to be reasonably human-editable

[Youssef Shoaib [MOD]]

Hmmm. I've heard of CashApp using JS for this purpose... They built some integration layer that allows JS to control what they want in their app.
Edit: it's called Zipline, and supports embedding Kotlin/JS code inside Kotlin/JVM

🤔 some of the commands being executed by the DSL invoke suspend functions interacting with the outside world

[Youssef Shoaib [MOD]]

Apparently:

Interface functions may be suspending. Internally Zipline implements setTimeout() to make asynchronous code work as it's supposed to in Kotlin/JS.

Zipline also supports Flow<T> as a parameter or return type. This makes it easy to build reactive systems.

Huh, looks interesting.

Might be a bit hard to generate code in zipline though, I think it's a bit too generic for what we need.
