Examples

Example 1:
try {throw "invalid argument"} catch {hint str _exception};
Example 2:
Template:Since: 123 try {if (_this != 123) throw "invalid argument"} catch {hint str _exception};
Example 3:
The correct usage of shorthand alt syntax: try { if (a > b) throw "Error: some error"; // OK // The command argument is static } catch { hint str _exception; }; try { _someFunc = { ..... }; if (a > b) throw (call _someFunc); // NOT OK // The command argument is dynamic // _someFunc is called first to get the value regardless of (a > b) outcome } catch { hint str _exception; }; try { _someFunc = { ..... }; if (a > b) then {throw (call _someFunc)}; /// OK // The command argument is dynamic // _someFunc is only called when (a > b) is true } catch { hint str _exception; };
