DISCLAIMER: These notes are from the defunct k8 project which precedes SquirrelJME. The notes for SquirrelJME start on 2016/02/26! The k8 project was effectively a Java SE 8 operating system and as such all of the notes are in the context of that scope. That project is no longer my goal as SquirrelJME is the spiritual successor to it.


It might be time to write improved JSON reading code.


Obtaining the callstack may be slow depending on the method, one thing I could do is create a callstack variable which contains simple information as to which method. It will essentially be a stack that gets pushed and popped from as the calls proceed. So it would contain a simple reference to a String and an integer for the line used. Though a line mapping would be needed for that. However, instead of a line mapping it can just be the internal PC location. If the stack trace is obtained then it can just determine the PC address based on said information. Although I could completely disregard line numbers. That would make debugging harder however. Using the PC address may be best, and if the stack trace is ever requested the PC address could be unmapped then. For the call stack, the current method would always be a bad address (-1?) and only filled in during jumps away. If an exception is thrown during the middle of a method it can be obtained anyway. Although setting to a bad address might not be needed at all since if it is at the top of the stack then it is known that it is currently being executed. One important thing to handle correctly is exiting of a method in a way where it acts like finally in all cases.


Clock skews mess with your sleep.


I might need a better register setup, perhaps just a map of lists. That would simplify the choice sets for the most part. Pretty much all of the stuff is duplicate code in RegisterChoices. So that might be the better plan.
