Bonehead

Retry blocks of code when they raise an exception.

What is it?

def insist(tries = Float::Infinity, *exceptions, &block)

Bonehead executes a block. If an exception is raised in the block, it retries executing it. After tries failed tries, the exception is re-raised.

Retry on all exceptions inheriting from StandardError, just like rescue.

Bonehead.insist 3 do
  raise "Fail!"
end

Retry on specific exceptions only, just like rescue. The block below is 3 times.

Bonehead.insist 3, TypeError do
  raise TypeError, "Fail!"
end

And the one below only once.

Bonehead.insist 3, TypeError do
  raise "Fail!"
end

It's easy to wait a while between retries.

Bonehead.insist 3 do |try|
  sleep 0.1 if try > 1

  raise "Fail!"
end
