<condition> is an expression as the ones evaluated by [doc:expressioneval]$(*)[/doc]
with the following extensions: If <condition> is a string, its length is evaluated: in this way a non-empty string causes the <condition> to be true, an empty string causes it to be false. If <condition> is an array, its size is evaluated: in this way a non-empty array causes the <condition> to be true, an empty array causes it to be false. If <condition> is a hash, the number of its entries is evaluated: in this way a non-empty hash causes the <condition> to be true, an empty hash causes it to be false. |
