Count Module Example

This example uses Count, together with a Simple Math module, to truncate a feed to half its original size. First, we pipe our feed into a Split module. This gives us two identical feeds to work with. One feed is piped into Count, which outputs a number: the number of items in the feed. We pipe this value into a Simple Math module and divide it in half. The other feed (after the split) is piped into a Truncate module, which allows us to limit the number of items in the output feed. Truncate requires a number value (the number of items you want output), so we just wire the Simple Math output into Truncate's numeric field, and we've cut the output feed in half.
