TOPLEVEL_BINDING #21

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
(1)
  str = "a=2"
  eval(str,TOPLEVEL_BINDING)

What is the expected output? What do you see instead?
Expect a to become 2.
Get: Unhandled Exception: Ruby.Runtime.RubyException: uninitialized 
constant TOPLEVEL_BINDING

What version of the product are you using? On what operating system?
Rev 86. Windows XP

Please provide any additional information below.
TOPLEVEL_BINDING is a binding object representing the Ruby top level and 
is needed for ERB in particular. Maybe a post-1.8.2 value?

TOPLEVEL_BINDING exists in 1.8.2, but Ruby.NET doesn't have it yet.

The following patch is wrong but it's probably a start.  It's wrong because, if 
I 
understand correctly, at that point in the code the toplevel frame is not known.
