Question

How can get the main binding? In other words, in the following code, how can I make it so that eval ignores all the assignments, etc. previously made in some_codes…some_codes?

some_codes
...
some_codes
eval(string_to_be_executed, binding)

Answer 1

The simplest way is to just create a binding at the top of the file:

block = Proc.new{}
# some_codez
# ...
# some more of teh codez
eval(string_to_be_evaluated, block.binding)
