Hey @borkdude, could you provide more context on this?

[borkdude]

@kolharsam Hi! I don't know a lot about this, but this was a request that came from the nREPL project. Possibly @bozhidar knows more.

I found some docs here: https://nrepl.org/nrepl/ops.html#lookup

In general it's best if you look at example messages sent back and forth using this:

https://docs.cider.mx/cider/troubleshooting.html#debugging-the-communication-with-nrepl

and then try to implement that.

@bbatsov could you please provide some context on this?

[bbatsov]

It's the op editors are supposed by default to resolve a symbol to a var and procure its definition location metadata (amongst others) https://nrepl.org/nrepl/ops.html#lookup

I think everything you need is here nrepl/nrepl@6291c2e

@bbatsov We don't need more context on the operation, that's pretty clear. But there is one open question here about something CIDER-specific:

I believe this is now implemented in 0.0.4
