Support lexical definitions?

[ribru17]

Hello, and thanks for the amazing project! It seems like right now the only symbols considered are ones that are exported or imported. Are there any plans to support lexical scopes and other types of references? E.g. something like this:

let myvar = 2

for (let i = 0; i < 5; i++) {
  let myvar = 7 // shadowing
  console.log(myvar)
}

console.log(myvar)

when running the indexer over this, it would be super cool to get separate symbols / references for the inner myvar and the outer myvar.

Thank you for your interest!
Yes, the current version does support scope resolution. You can see that when defining a rule, it also extracts the namespace:

gossiphs/src/rule.rs

Line 43 in 0635a51

namespace_grammar: r#"

After that, gossiphs uses the nesting depth to prune some symbols, in order to reduce internal variables from leaking outside the file.
However, the current implementation is still quite rough — it’s barely usable, as it simply sets a depth threshold and aggressively ignores all internal symbols.

gossiphs/src/graph.rs

Line 96 in 0635a51

let namespaces: Vec<_> = file_context

So for the scenario you mentioned, it sounds like the namespace mechanism can support the logic you’re describing.
However, gossiphs has so far been more focused on relationships between files, so progress on this part has been relatively slow.

Ah, ok I think I understand. Thanks for the response! Would you be open to PR(s) for more namespace rules for some languages?

Yes, absolutely — PRs are always welcome! :)

Apologies that the code has become a bit hard to read due to ongoing iterations.
I might take some time soon to reorganize it with the help of an LLM.
