What Ilya proposes would indeed be cleaner - I think we could attach directory_entry or path/file_type to the completion result.

On the other hand while this is a hack, it's simple and it works, and the cleaner solution doesn't bring any concrete benefit at this point.

I think we should leave this be and revisit if we start querying headers from the index. (At that point we'll want more robust path info to deduplicate sema and index results).



================
Comment at: clangd/CodeComplete.cpp:352
           C.SemaResult->Kind, C.SemaResult->Declaration, ContextKind);
+      if (Completion.Kind == CompletionItemKind::File &&
+          Completion.Name.back() == '/')
----------------
this probably deserves at least a comment mentioning that Sema could provide more semantic info here.


================
Comment at: clangd/Protocol.h:706-707
   File = 17,
   Reference = 18,
+  Folder = 19,
 };
----------------
This is a type outside of the core must-be-supported range, so we probably need to add the logic to ClangdLSPServer to respect the client capabilities (see `adjustKindToCapability`). This could be a separate patch, as it's basically plumbing.
