After the method's identifier comes the parentheses # +:paren+ and the method parameters under +:params+. # # Next is the method body, starting at +:bodystmt+ (+stmt+ meaning statement), # which contains the full definition of the method. # # In our case, we're simply returning a String, so next we have the # +:string_literal+ expression. # # Within our +:string_literal+ you'll notice two <code>@tstring_content</code>, # this is the literal part for <code>Hello, </code> and <code>!</code>. Between # the two <code>@tstring_content</code> statements is a +:string_embexpr+, # where _embexpr_ is an embedded expression. Our expression consists of a local # variable, or +var_ref+, with the identifier (<code>@ident</code>) of +world+. # # == Resources # # * {Ruby Inside}[http://www.rubyinside.com/using-ripper-to-see-how-ruby-is-parsing-your-code-5270.html] # # == Requirements # # * ruby 1.9 (support CVS HEAD only) # * bison 1.28 or later (Other yaccs do not work) # # == License # # Ruby License. # # Minero Aoki # aamine@loveruby.net # http://i.loveruby.net class Ripper; end
