I have added support for documentation of delegate class method in ruby. New regex for matching delegate
Also, I have refactored code little bit. Instead of defining separate functions for fields, association, validations, delegate, I have created a single function.
def handle_model_helpers(self,edit,r,helper_comment): self.indent = r.group("indent") self.lines =  self.lines.append(helper_comment) self.run_command(edit,self.concat())
Test it and merge into the main branch :)
Note: I also attached updated yardgen.py file
