| 06:15:58 |  fouric | does anyone have opinions about my attempt to turn the cl-sdl2 with-event-loop loop into a recursive function? https://gist.github.com/fouric/8068a1ce3e9a0ae8ce664c2b182b2e1d |
| 06:16:55 | fouric | i feel like i could somehow separate out all of the boilerplate (like allocating the sdl-event struct and handling lisp messages) but i can't figure out how |
| 06:17:16 | fouric | the original macro definition is at https://github.com/lispgames/cl-sdl2/blob/a963ea57c7d43761f28314f0642fcae18fb51174/src/events.lisp#L189 |
| 06:17:38 | fouric | and you might use it like https://github.com/lispgames/cl-sdl2/blob/a963ea57c7d43761f28314f0642fcae18fb51174/examples/basic.lisp#L50 |
| 07:01:49 |  luismbo | The first thought that comes to mind is that tail recursion is not mandatory so you might end up with actual recursion and overflow the stack. |
| 07:03:27 | fouric | I'm assuming the implementation has TCO |
| 07:04:08 | fouric | the reason I'm rewriting it in loop form at all is so I can hotpatch the event-processing logic while the program runs |
| 07:04:13 | fouric | I guess I should have explained that |
| 07:04:51 | fouric | * I'm assuming the implementation has TCO |
| 07:07:42 | luismbo | Can you have your cake and eat it too? If TCO kicks in, you won't be able to redefine the inner function midway through the loop, right? |
| 07:08:03 | luismbo | 🤔 |
| 07:12:31 | luismbo | Couldn't you simply move the looping to the outer function and have the inner function's return value determine whether the loop should stop? |
| 07:13:15 | luismbo | In any case, your code looks much better than that huge original macro. 👍 |

Can you have your cake and eat it too? If TCO kicks in, you won't be able to redefine the inner function midway through the loop, right? Yup! I've done exactly this before and it works flawlessly - at least on SBCL, which is the thing I'm concentrating on right now. |
| 00:49:52 | fouric | That is, I both get TCO, and I gain the ability to redefine loop-like constructs while they're running. |
| 00:50:02 | fouric | erm, i get the latter as a result of the former |
| 00:51:33 | fouric | the problem is that almost half of INNER is just the SDL2 boilerplate, and i want to move it into a separate macro - but i can't figure out what the macro should look like |
