main_block.rb

This Ruby code snippet demonstrates a conditional block that ensures code within it only executes when the script is run directly, not when it’s required as a module or included in another script. It returns nil as it doesn’t perform any operation.

Ruby code snippet

if __FILE__ == $0
  # Code block to be executed only if the script is run directly

  # Add your script's main logic here
end
#=> nil
