Incomplete documentation generated via robot.libdoc (YARD::Registry loses load data)

[lumendes]

Hi,
Not sure if this is still actually being maintained, but here is goes :)
I don't seem to be able to get full documentation (missing args and ruby comments) via robot.libdoc.

Environment:

Ubuntu 16.04
ruby-2.4.1
yard (0.9.9)
robot_remote_server (2.5.6)

TestServer.rb:

require 'robot_remote_server'
class TestServer
   #Keyword documentation
   def keyword(value)
      puts "Hello " + value + " !"
   end
end

if __FILE__ == $0
  RobotRemoteServer.new(TestServer::new, host='localhost', port=8270)
end

YARD docs generated from same path:
yardoc TestServer.rb

Serving:
ruby TestServer.rb

Robot docs generation:
python -m robot.libdoc Remote::http://127.0.0.1:8270 test.html

Result:
Keyword args and comments info missing from test.hmlt file.

Workaround
I am not familiar with Ruby, but a workaround I've found was to modify robot_remote_server.rb source file with additional load and force caching in get_keyword_arguments method:

def get_keyword_arguments(name)
   ++ @reg.load!()
   (...)
