How to check if script in a file a method?

hello,

given a text string with ruby code, that my program evaluates at some
point
inside an anonymous module, is there a way to analyse the code without
evaluating it inside a module to tell if it implements a particular
method?

i have a bunch of strings like that and i want to present the list of
them
to the user but i need to show what these scripts do so that she could
choose. after that i do evaluate the chosen one in a module and use it.
evaluating all of them and using respond_to? before displaying the
selection
list seems ugly. is parsing the only alternative?

something similar to lisp’s quote operator (which turns any list in to
just
a data list)?

thanks
