Next-Level Assertion Extensions

Here are some final thoughts on how to further improve your assertions:

  • Change any often-triggered assertions into proper error messages with fault tolerance. Users don't like seeing assertion messages. They're kinda like gibberish to ordinary mortals.
  • Add extra context information in the assertion message (i.e. add an extra information string). This is much easier to read than a stringized expression, filename with line number, or multi-line stack trace.
  • Add unique codes to assertion messages for increased supportability. Although, maybe not, because any assertion that's triggering often enough to need a code, probably shouldn't remain an assertion!
  • Inlined assertion function? Why use macros? Maybe these assertions should instead be an inline function in modern C++? All I can say is that old habits die hard, and I still don't trust the optimizer to actually optimize much.
