Try to add eclair/ldk support #181

Closed PurpleTimez closed 4 months ago

PurpleTimez commented 5 months ago

I don't understand the framework, and dunno if other implems support can be useful.

Eclair Support

From eclair documentation's (README.md), there is an API where one can install plugin written in Scala, Java or any JVM-compatible language.

I think from then a plugin could be designed to expose a GRPC interface and this interface driven by a sim-lib module to act sim actions (get_info, send_payment, track_payment, get_node_info, list_channels).

LDK Support

LDK has a sample node called ldk-sample. It is a test lightning node that one can run on the command-line a REPL fashion. Internally, it's using a module (cli.rs) which is pipping user command to the internal interface of the LDK library.

I think a GRPC interface alternatively integrated in ldk-sample runtime, instead of the command-line cli could be a way to have a LDK runtime driven by sim-lib. Accessing directly the LDK interface allow a stable interface to act on sim actions (get_info, send_payment, track_payment, get_node_info, list_channels).

I don't know if the two support approaches will work end-to-end, though I think it's an interesting way to have eclair / ldk support in sim-ln. I don't know how much hacking work it is, I can try.

See #26 for ongoing discussion on multi-impl support

Left thoughts here. Sounds eclair support better to prioritize. Dunno if way proposed is not too much maintenance.

Closing boilerplate PR after discussion in #26, feel free to re-open an eclair implementation if reasonably achievable.
