Error Handling Example

This example demonstrates how to raise exceptions with the throw keyword and recover from them using try / catch blocks in TechScript.

Code (errors.txs)

do divide(a, b)
    when b == 0
        throw "Division by zero error!"
    end
    send a / b
end

try
    say "Attempting valid division..."
    res = divide(10, 2)
    say $"Result: {res}"
    
    say "Attempting invalid division..."
    res_err = divide(10, 0)
    say $"Result (should not print): {res_err}"
catch error
    say $"Caught expected error: {error}"
end

say "Program continues running cleanly after catch block."

Running the Example

tech run errors.txs

Expected Output

Attempting valid division...
Result: 5
Attempting invalid division...
Caught expected error: Division by zero error!
Program continues running cleanly after catch block.
