Not much here right now, just a placeholder because we are rushing a release…


ParseTree is a C extension (using RubyInline) that extracts the parse tree for an entire class or a specific method and returns it as a s-expression (aka sexp) using ruby’s arrays, strings, symbols, and integers.

As an example:

class Example def conditional1(arg1) if arg1 == 0 then return 1 end return 0 end end


[:defn, “conditional1”, [:scope, [:block, [:args, “arg1”], [:if, [:call, [:lvar, “arg1”], “==”, [:array, [:lit, 0]]], [:return, [:lit, 1]], nil], [:return, [:lit, 0]]]]]
