# Handler Chain
#
# A chain of handlers that respond to call. Invoking handle(*args) on the chain
# will call the handlers with the given args until one of them returns a result
# that is truethy (i.e. not false or nil).
#
# Extracted from the dispatcher so we can also handle exceptions here in the
# future.
#
module Nickserver
class HandlerChain
def initialize(*handlers)
@handlers = handlers
end
def handle(*args)
result = nil
_handled_by = @handlers.find{|h| result = h.call(*args)}
result
end
