Hi, I'm trying to run "yard graph" but I get the following error:

Any ideas?

I went though the backtrace and made the following changes:

lib/yard/code_objects/base.rb:325:in method_missing()
def method_missing(meth, *args, &block)
if meth.to_s =~ /=$/
self[meth.to_s[0..-2]] = args.first
elsif instance_variable_get("@#{meth}")
self[meth]
else
begin
super
rescue
end
end
end

templates/default/class/dot/superklass.erb:
<% if object.superclass && object.superclass.path != "Object" %>
<%= format_path object %> -> <%= format_path object.superclass %>;
<% end %>

templates/default/default/module/dor/info.erb:
<%= h(" : #{obj.tag(:return).types.first}") if obj.has_tag?(:return) && obj.tag(:return).types && obj.tag(:return).types.size > 0 %>\l

This is more of a hack though...

I "fixed" the superklass.erb template:

  <%= format_path object %> -> <%= format_path object.superclass %>;
<% end %>

same issue here with Ruby 1.9.2

[zdavatz]

Ok, fixes work! Thanks!

Can anybody provide a minimal case that reproduces this issue? I've applied mattetti's patch, but I'd like to know how to confirm this is fixing an issue.

Regards

[lsegal]

I've tested it against Arachni and it works. I'll push a commit and close this ticket now.

Thank you for taking care of this!

[mattetti]

Thanks indeed, I'll check that it works properly on my current project.
