Separate stateful executor without the UI

[Madd0g]

hey, I'm new to Elixir, I'm wondering if I could get some guidance from experts.

I'm interested in Livebook because I'm a big fan of on-the-fly compile/execute of new code (typically referred to as scripting). I looked at the repo and was kind of able to follow along and see how code gets compiled and run.

I'm wondering if anyone knows of a library that achieves the same without the interactive UI concept, I want to create a stateful executor where I can not only eval a piece of code, but iterate on it like the notebook - in a state-aware container that I can decide to run once or multiple times, update the code in it or dispose of it.

I see some discussions about running a single script from the CLI. It's that ability that I'm curious about but want to be able to:

1. use it from elixir code (as a library)
2. iterate on the "code container" and not just run once like the CLI runner

Thanks

As far as I know there is no library, but you can use the code from Livebook as a starting point. I would probably get the code from some of its initial versions, as it would have less features and be a smaller starting point. :)

one day I'll be brave and actually try it, thank you for the reply!

You may be mostly interested in Livebook.Runtime.Evaluator, see the tests for the evaluation API. For basic functionality it could be heavily stripped down :)

I read that file, didn't see the tests, very helpful, appreciate the link
