How to get rid of a ruby ​​warning: an already initialized constant

Question

I am trying to override the gem constant dynamically, so I do not need to change the stone itself.

require 'xmlrpc/client' XMLRPC::Config.const_set("ENABLE_NIL_PARSER", true) warning: already initialized constant ENABLE_NIL_PARSER 

Can I get rid of the warning?

Answer 1

A simple way:

 v, $VERBOSE = $VERBOSE, nil # code goes here $VERBOSE = v 

Answer 2

You can even wrap it in a block like this

 def ignoring_warnings(&block) begin v, $VERBOSE = $VERBOSE, nil block.call if block ensure $VERBOSE = v end end
