module StructuredWarnings::ClassMethods

If you require "test/unit" after structured_warnings you have to require "structured_warnings/test" manually, otherwise the test extensions will be added automatically.

Public Instance Methods

warner() click to toggle source

Gives access to the currently used warner. Default is an instance of StructuredWarnings::Warner

# File lib/structured_warnings.rb, line 23
def warner
  Dynamic[:warner]
end

with_warner(warner) { || ... } click to toggle source

Executes a block using the given warner. This may be used to suppress warnings to stdout, but fetch them and redirect them to somewhere else.

This behaviour is used in the StructuredWarnings::Assertions

# File lib/structured_warnings.rb, line 15
def with_warner(warner)
  Dynamic.let(:warner => warner) do
    yield
  end
end
