Eval / current binding

ruby-talk
1

Hey,

  So I've looked at module_eval, class_eval, and Kernel#eval

  and I'm pretty sure that what I want to do is to do Kernel#eval("blah ...
some code", global_environment)

  where by global_environment I mean the global_context or the
global_binding

  The problem now ... is that I don't know how to access this global
environment / global context / global binding ... is there a function that I
can call that will

  (1) get me the global binding / global env / global context or
  (2) a function that I can call that will get me the current binding / env
/ context

Thanks,
(when replying please cc the list and me)

The TOPLEVEL_BINDING constant...but the standard disclaimer is don't
use eval (depends on what you're doing though). It is generally not
safe unless you have 100% control over the input, because it can do
everything ruby can (i.e., eval doesn't run in any kind of sandbox),
so in an untrusted context, it's dangerous.
