Instance Method Details

#process(input, verbose = nil, file = "(string)", line = -1)) ⇒ Object

Main driver for ParseTree. Returns a Sexp instance containing the AST representing the input given. This is a UnifiedRuby sexp, not a raw sexp from ruby. If you want raw, use the old parse_tree_for_xxx methods… Please tell me if/why you want raw, I’d like to know so I can justify keeping the code around.
