Recover in AngelScript

void mayPanic() {
    throw("a problem");
}

void main() {
    try {
        mayPanic();
        print("After mayPanic()");
    } catch (any e) {
        print("Recovered. Error:\n " + e);
    }
}

AngelScript doesn’t have a direct equivalent to Go’s recover function. Instead, we use a try-catch block to handle exceptions, which is similar in concept to recovering from panics.

The mayPanic function now throws an exception instead of calling panic. In the main function, we wrap the call to mayPanic in a try-catch block.

If an exception is thrown in mayPanic, it will be caught in the catch block, which prints the error message. This is analogous to the deferred function with recover in the original Go code.

The print statement after mayPanic() is now inside the try block. If mayPanic throws an exception, this line won’t be executed, similar to how it wouldn’t be reached in the Go version due to the panic.

To run this code:

$ angelscript recover.as
Recovered. Error:
 a problem

This example demonstrates exception handling in AngelScript, which serves a similar purpose to panic recovery in other languages. It allows the program to catch and handle errors gracefully, preventing the entire program from crashing due to an unexpected error in one part of the code.
