Usage;T@o; ;[I"PRipper provides an easy interface for parsing your program into a symbolic ;TI"'expression tree (or S-expression).;T@o; ;[I"JUnderstanding the output of the parser may come as a challenge, it's ;TI"@recommended you use PP to format the output for legibility.;T@o:RDoc::Markup::Verbatim;[I"require 'ripper'

;T: @format0o; ;[I"MYou can see in the example above, the expression starts with +:program+.;T@o; ;[I"SFrom here, a method definition at +:def+, followed by the method's identifier ;TI"O:@ident. After the method's identifier comes the parentheses ;TI"8+:paren+ and the method parameters under +:params+.;T@o; ;[I"RNext is the method body, starting at +:bodystmt+ (+stmt+ meaning statement), ;TI"6which contains the full definition of the method.;T@o; ;[I"GIn our case, we're simply returning a String, so next we have the ;TI""+:string_literal+ expression.;T@o; ;[
I"SWithin our +:string_literal+ you'll notice two @tstring_content, ;TI"Sthis is the literal part for Hello, and !. Between ;TI"Nthe two @tstring_content statements is a +:string_embexpr+, ;TI"Swhere _embexpr_ is an embedded expression.
