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 25
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 17
def with_warner(warner)
  Dynamic.let(:warner => warner) do
    yield
  end
end
