Is it possible to chain two matchers and only yield the block given to expect once?

[Kris Leech]

Is it possible to chain two matchers and not have to yield the block given to expect twice?

The problem is yielding the block twice changes the test.

class FirstMatcher
  def matches?(block)
    @result = record_something do
      block.call # block called for first time
    end
    return true
  end

  def supports_block_expectations?
    true
  end

  def second_matcher?
    SecondMatcher.new
  end
end

class SecondMatcher
  def matches?(block)
    @result = record_something do
      block.call # block called for second time, can I get the original @result somehow?
    end
    return true
  end

  def supports_block_expectations?
    true
  end
end


# usage

expect { something }.to first_matcher.second_matcher

Many thanks, Kris.

In RSpec 3.0, there's not.  In 3.1, there will be:

Use the `and` chaining:

expect { }.to first_matcher.and second_matcher

...and it should just work.

Can't wait, I'll keep my eyes open for a 3.1 beta. Really enjoying Rspec 3.

Actually I can just point at the master branch and try it out now.

Many thanks.
