UCE Docs / DValue::to_bool

Signature

bool DValue::to_bool(bool default_value = false) const

Parameters

bool : fallback returned when conversion is not possible
return value : converted value or the fallback

Converts strings, numbers, bools, pointers, and maps to bool. Text such as true, yes, on, 1, false, no, off, 0, and null is recognized; non-empty unparseable strings are truthy; empty strings use the default. Multi-child maps are true when non-empty.

Example

DValue value;
value = "true";
print(value.to_bool() ? "true\n" : "false\n");
Output
true
