`Event` decoding API #32

Closed devictr closed 2 years ago

devictr commented 2 years ago

Hi @esaulpaugh,

I initially asked on gitter, but thought I'd create an issue here directly. Is there a way to decode events, like there is Function.decodeCall() ? If not, I'd be happy to help implement that.

I really appreciate all the work you've done for this lib, it saved me so much time and the API is very well designed.

Thanks!

I've been confused about how exactly to interpret the abi-spec with regards to events (and to some extent, packed encoding). Ideally headlong would be a full and faithful implementation of https://docs.soliditylang.org/en/latest/abi-spec.html and I haven't had much time to test against other frameworks or solidity (or other EVM languages like vyper for that matter). I actually don't really have solidity experience.

I'm not looking to create a whole event-handling framework, but if you could write some low-level methods which would facilitate the building of such frameworks on top of headlong, that would be very helpful.

Sounds good. I think I will implement something that looks like what ethereumj does here, but using your types and helper functions of course
