Should this be attr_writer or attr_accessor?

There was a problem hiding this comment.
In the middle of typing, we may find empty arguments, so we have to handle that. Also, we need to account for symbol and string nodes as arguments.
Suggested change
| node.arguments.arguments.select { |arg| arg.respond_to?(:unescaped) }.map(&:unescaped) | |
| arguments = node.arguments.arguments | |
| return [] unless arguments | |
| arguments.filter_map do |arg| | |
| case arg | |
| when Prism::StringNode | |
| arg.unescaped | |
| when Prism::SymbolNode | |
| arg.value | |
| end | |
| end |

Motivation
Shows references for methods defined with
attr_reader,attr_writer,attr_accessorCloses #2668
Implementation
attr_reader,attr_writer,attr_accessorare just methods, so on call node if we detect one of these methods, and one of the arguments match the target method name, add the reference.Automated Tests
