Method visibility_of

codegraph-kernel/src/ruby.rs:361–377

rubyExtractor.getVisibility — walk the previousNamedSibling chain (unbounded, through non-matching siblings); the first `call` sibling whose `method` text is private/protected/public decides; else public. Bug-for-bug: a BARE `private` line parses as identifier (invisible), and a matching call poisons every later sibling def regardless of ruby's actual arg-scoped semantics.

            if s.kind() == "call" {
                if let Some(method) = s.child_by_field_name("method") {
                    match self.text(method) {
                        "private" => return 2,
