Subject: [ruby-core:50059] [ruby-trunk - Feature #7349] Struct#inspect needs more meaningful output


Issue #7349 has been updated by mame (Yusuke Endoh).


This is not a bug.  This ticket has been moved to the feature tracker.

I'm not against this proposal, but I don't think that people normally check the singleton class to know Struct fields.  You may want to use Struct.#members:

  p Point.members #=> [:x, :y]

It is shorter than ancestors.

Feature #7349: Struct#inspect needs more meaningful output

When inheriting directly from Struct.new, Class#ancestors shows a meaningless anonymous Class:

    class Point < Struct.new(:x, :y)

      def distance
        ((x ** 2) + (y ** 2)) ** 0.5
      end

    end

    Point.ancestors
    # => [Point, #<Class:0x007fe204a1a228>, Struct, Enumerable, Object, Kernel, BasicObject]

Perhaps, the anonymous Class could list the Struct's fields?

    #<Class:x, y>
