Exceptions

Currently, There are 6 Exceptions in StoryScript.

1. InvalidSyntax - Something wrong with the Syntax.
2. AlreadyDefined - The variable, function, module, or namespace is already defined.
3. NotImplementedException - The function or module is not implemented.
4. NotDefinedException - The exception, variable, module, namespace, or function does not exist.
5. GeneralException - a General Exception. Mostly the Interpreter will never throw this Exception.
6. DivideByZeroException - Dividing numbers with zero is not allowed.
7. InvalidValue - The input value is invalid.

Throwing exception

To throw an Exception, You need to follow this format:

throw [Exception] [Description]

The description is optional. Some Exception has a default Description, And some don't. For example:

throw NotImplementedException

Output:

NotImplementedException: This feature is not implemented

Example 2:

throw AlreadyDefined "This value is already defined!"

Output:

AlreadyDefined: This value is already defined!
