# <!-- rdoc-file=error.c --> # The Warning module contains a single method named #warn, and the module # extends itself, making Warning.warn available. Warning.warn is called for all # warnings issued by Ruby. By default, warnings are printed to $stderr. # # Changing the behavior of Warning.warn is useful to customize how warnings are # handled by Ruby, for instance by filtering some warnings, and/or outputting # warnings somewhere other than $stderr. # # If you want to change the behavior of Warning.warn you should use # +Warning.extend(MyNewModuleWithWarnMethod)+ and you can use `super` to get the # default behavior of printing the warning to $stderr. # # Example: # module MyWarningFilter # def warn(message, category: nil, **kwargs) # if /some warning I want to ignore/.match?(message) # # ignore # else # super # end # end # end # Warning.extend MyWarningFilter # # You should never redefine Warning#warn (the instance method), as that will # then no longer provide a way to use the default behavior. # # The `warning` gem provides convenient ways to customize Warning.warn. # module Warning # <!-- # rdoc-file=error.c # - warn(msg, category: nil) -> nil # --> # Writes warning message `msg` to $stderr. This method is called by Ruby for all # emitted warnings. A `category` may be included with the warning. # # See the documentation of the Warning module for how to customize this. # def self?.warn: (String message, ?category: :deprecated | :experimental | nil) -> nil end
