Execute arbitrary code with different level of error messaging

/ Published in: Ruby

You can turn off warnings for a section of your code by setting $VERBOSE to nil. Even better is to codify this in a method. Since this method takes a block as its parameter, you can now pass it arbitrary chunks of code to execute without warnings.

Copy this code and paste it in your HTML 
  1. def silently(&block)
  2.   warn_level = $VERBOSE
  3.   $VERBOSE = nil
  4.   result = block.call
  5.   $VERBOSE = warn_level
  6.   result
  7. end
  8.  
  9. # e.g.
  10. silently { require 'net/https' }
