Warning: The Experiment
Ruby's Warning module learned some new tricks in Ruby 2.7:
Support for muting different categories of compile warnings has been introduced. This is a mechanism on top of the warning level reflected by the $VERBOSE variable.
You can now silence deprecation warnings: These are aspects of the language which will be removed or changed in a future version of Ruby. One example is the infamous: warning: Using the last argument as keyword parameters is deprecated; maybe ** should be added to the call
It is also possible to mute experimental features warnings: These are new features of Ruby, which might not have a stable API yet, like the new pattern matching
Per Ruby
Warning[:experimental] = false
Warning[:deprecated] = false
Per CLI
$ ruby -W:no-deprecated
$ ruby -W:no-experimental
Per ENV Variable
$ RUBYOPT="-W:no-deprecated" ruby
$ RUBYOPT="-W:no-experimental" ruby
