Resolving Go in Go

[untold lava]

Hey all,

I'm trying to create a tool in Go that can take a function definition, resolve all of the symbols being referenced in the function, and then locate all of their definitions relative to the project root / vendor directory.

Is there a way to leverage one of the Go language servers to locate the function definitions?
I'm familiar with go-tree-sitter, which can parse Go code and pull out the symbol names, however I need to be able to locate their exact definition locations regardless of where they are in the project.

@upbeat quiver Would you happen to know how to accomplish this?

@untold lava https://pkg.go.dev/go ?
https://pkg.go.dev/golang.org/x/tools/go ?

I'm pretty sure it's in there, I don't know where precisely.

Most likely, idk how to do it tho.
You can lookup the LSP spec

Yeah, I put together a bash script earlier which uses the gopls CLI, but I was hoping to call the functions directly from my Go CLI tool so I can avoid writing everything in BASH

[upbeat quiver]

have you tried reading the source for the gopls cli ?
I mean if it already do what you need, sounds "easy" enough to "borrow" the code source.

Let me try something with this

I was under the impression that they weren't exporting stuff but let me try again - it may have just been me blindly trusting autocomplete

[untold lava]

Yeah the problem is that their code is internal so I can't import it at all

Borrowing, I'm not sure about since I'd need to basically fork the entire repo for it to work properly

There are going to be limits to what you can do. I think running functions will be simplest.
There's a thing called FFI that might help? Or that might just be from C to other languages.
