Question: is it possible to include local vars/calls in structure?

consider snippet:

private func foo(dictionary: [Int: Int]) -> Int {
    let a = 2
    dictionary.flatMap { foo in return foo }
    return 1
}

SourceKitten Produces:

  "key.substructure" : [
    {
      "key.kind" : "source.lang.swift.decl.function.free",
      "key.offset" : 22,
      "key.nameoffset" : 27,
      "key.namelength" : 27,
      "key.bodyoffset" : 63,
      "key.bodylength" : 73,
      "key.accessibility" : "source.lang.swift.accessibility.private",
      "key.substructure" : [
        {
          "key.kind" : "source.lang.swift.decl.var.parameter",
          "key.offset" : 31,
          "key.nameoffset" : 0,
          "key.namelength" : 0,
          "key.length" : 10,
          "key.typename" : "[Int: Int]",
          "key.name" : "dictionary"
        },
        {
          "key.kind" : "source.lang.swift.decl.var.parameter",
          "key.offset" : 103,
          "key.nameoffset" : 0,
          "key.namelength" : 0,
          "key.length" : 3,
          "key.typename" : "foo",
          "key.name" : "foo"
        }
      ],
      "key.name" : "foo(_:)",
      "key.length" : 115
    }
  ],
  "key.offset" : 0,
  "key.diagnostic_stage" : "source.diagnostic.stage.swift.parse",
  "key.length" : 138
}

I've expected to see a here or at least expr.call for flatMap. However it might be that structure is just structure: but then I do not realize how to distinct between function parameters and foo parameter in closure (needed for realm/SwiftLint#415)

Non related:
I wanted to debug it myself, but

xcrun sourcekitd-test
xcrun: error: unable to find utility "sourcekitd-test", not a developer tool or in PATH

Any advice on that?

SourceKitten's Structure builder is really just a thin wrapper around SourceKit's editor.open request. See Structure.swift and Request.EditorOpen which then is sent and the response from SourceKit is mapped to a Dictionary<String, SourceKitRepresentable>, then finally converted to JSON and printed.

So in other words, to expand the contents of Structure, you'd need to do that in SourceKit itself.

sourcekitd-test is a tool built to test SourceKit that was originally included in some early Xcode 6 betas, but subsequently removed, so it hasn't shipped with Xcode since Xcode 6 beta 3-4 IIRC. You can find the source for the tool here: https://github.com/apple/swift/tree/master/tools/SourceKit/tools/sourcekitd-test

I hope that helps!

Since it works as designed I'm closing the issue
