Yes, this is already planned. I am currently trying to find out what is ruby and what is Rails and what is the diferrence etc.
So far I understand that Ruby is a language and there is also rhtml format which is like php but with Ruby as a language, so we will have to cover these.
Ok, so it is clear, we need to cover Ruby and shoyuld not care about rails. So as I understand there is pure ruby (.rb files) and HTML + ruby (.rhtml), right?
