Assisting development tools through inserted code statements

A computer system, comprising:

• a processor;
• and
• a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the computer system to implement:
• a runtime environment having executable instructions stored in a memory operable to execute code that includes a statement that indicates information regarding whether notification is to be sent to a development tool if exceptions are encountered while the code is executing, wherein executing the code comprises setting a property of a runtime object that is accessible to the runtime environment, the property indicating that the notification is to be sent to the development tool if an exception is or would be handled in a scope associated with the code, and wherein the property is not inherited across different calls;
• an object operable to encode the information in a property settable by the statement, the property associated with a scope, the property being accessible by the runtime environment;
• and
• an exception manager operable to evaluate program state that existed in the runtime environment when an exception is encountered while executing the code, the exception manager further operable to determine whether to send the notification to the development tool based on the program state and the property, the exception manager evaluating program state by searching for an exception handler that will handle the exception, wherein if a stack frame that has the exception handler is found during the searching, then determining if the stack frame indicates that a property is set of a debug object, the property accessible to the runtime environment, the property indicating whether the debugger is to be called for exceptions handled by the exception handler, the exceptions potentially occurring outside of a scope having the stack frame.

A computer storage memory device having computer-executable instructions stored thereon that, upon execution by a computer system, cause the computer system to:

• during execution of code in a runtime environment, execute a statement of the code, the statement providing information regarding a notification, if any, to send to a debugger if exceptions occur while the code is executing, wherein executing the statement of the code comprises setting a property of a runtime object that is accessible to the runtime environment, the property indicating that the notification is to be sent to the debugger if an exception is or would be handled in a scope associated with the statement, and wherein the property is not inherited across different function calls;
• encounter an exception while executing the code;
• evaluate program state that existed in the runtime environment when the exception was encountered, the evaluating program state comprising searching for an exception handler that will handle the exception,
• if a stack frame that has the exception handler is found during the searching, then determining if the stack frame indicates that a property is set of a debug object, the property accessible to the runtime environment, the property indicating whether the debugger is to be called for exceptions handled by the exception handler, the exceptions potentially occurring outside of a scope having the stack frame;
• and
• based on the program state and the information, determine the notification, if any, to send to the debugger in response to the exception.
