$isSet Checks if a variable is set (non-empty) |
Usage |
<boolean> $isSet(<data:variant>) |
Description |
| Returns 1 if <data> is actually set to some non-empty value and 0 otherwise. If <data> is a variable, then this function simply checks if the variable is set. If <data> is a constant then this function checks if the constant is non empty. Since KVIrc treats empty strings as unset values then this function could be also called isNonEmpty and it is the perfect opposite of $isempty |
