How should I call eval from member function that binds to global
context?
Something like

$binding = binding
class InterpreterCallback
def methods(expr)
begin
return eval(expr, $binding).class.instance_methods(false).sort
rescue ScriptError, StandardError
printf “ERR: %s\n”, $! || ‘exception raised’
return []
end
end
end

but this does not work when I am calling InterpreterCallback::methods
from C++ (for example when new local variable in the global context is
created).

Also I do not understand following

This code:

puts eval(“var” ).class
puts eval(“var”).class.instance_methods(false).sort
var = “”;

produces:

NilClass
&
^
inspect
nil?
to_a
to_f
to_i
to_s
|

and this code

puts eval(“var” ).class
puts eval(“var”).class.instance_methods(false).sort

produces

undefined local variable or method `var’ for main:Object (NameError)

which is exactly what I would expect in the first case also.

Thank you
