| 00:29:17 | FromDiscord | <Elegantbeef> Right you want to store state which means you want a closure |
| 00:29:23 | FromDiscord | <Elegantbeef> I did not get that from your first message |
| 00:57:01 | FromDiscord | <.tokyovigilante> Is there a best practice for object initialisation? I'm porting over an music player app which has a number of objects wrapping things like audio interfaces, track objects, network resources etc, that are relatively persistent and need some initialisation (connecting to a system audio server, loading codecs etc). There doesn't seem to be any sort of init() function that's called by default when an object is created. |
| 01:06:28 | FromDiscord | <Elegantbeef> `proc init(_: typdesc[YourType], ....): YourType)` Is what you'll want to do |
| 01:06:42 | FromDiscord | <Elegantbeef> Nim does not have constructors aside from `T(a: b, c: d)` |

| 03:15:34 | FromDiscord | <.tokyovigilante> And then I should expect to be able to call YourType.init()? |
| 03:16:07 | FromDiscord | <.tokyovigilante> it doesn't seem to like object.yourType = YourType.init() currently |
| 03:18:38 | FromDiscord | <.tokyovigilante> Ah, but it does when I export the init proc properly, thanks! |
| 03:22:12 | FromDiscord | <.tokyovigilante> And presumably these object carrying internal state should be stored as refs? |
| 03:23:34 | FromDiscord | <Elegantbeef> @.tokyovigilante I will never give a single response to whether you need a ref 😄 |
| 03:23:42 | FromDiscord | <Elegantbeef> it depends is the only good response |
| 03:25:56 | FromDiscord | <.tokyovigilante> In this case I'm going to assume yes, as the assignment to object.yourType is I assume a copy-assign, so my initial object is deallocated, calls my `=destroy` function, which promptly deinits all the internal C pointers, and causing a crash when they are subsequently referenced by the copy.🤯 |
| 03:26:12 | FromDiscord | <Elegantbeef> `sink MyObject` where you give up resources |
| 03:26:28 | FromDiscord | <Elegantbeef> You do not need to use references cause of destructors, you use the move semantics as your friend |
| 03:27:15 | FromDiscord | <.tokyovigilante> Ah right, clearly I need to actually read these pages about memory management. |
| 03:29:29 | FromDiscord | <Elegantbeef> https://nim-lang.org/docs/destructors.html#sink-parameters will get you caught up |

| 18:14:00 | FromDiscord | <requiresupport> so I'm working with `StreamServer `using `chronos`, and I'd like to create an object based on StreamServer with other additional fields that I need. myStreamServer, then I'd like to use the `createStreamServer` function and cast it to my object `myStreamServer` .. I've noticed this was done in Scorper but tried similar method and failed miserably. Anyone can give a quick example with noob explanation? |

| 21:15:48 | PMunch | To be fair I'm not using this to parse random HTML, I'll just be using this to do a verifiable one-time job of adding id's to HTML tags |
| 21:16:07 | FromDiscord | <nnsee> yeah fwiw I think it'd work fine |
| 21:16:12 | FromDiscord | <nnsee> i just had to post it |
| 21:21:41 | FromDiscord | <bostonboston> I like the streams implementation for the interface type feel |
| 21:23:06 | FromDiscord | <Elegantbeef> My main issue with it is it relies on using inheritance so everything is boxed |
| 21:23:27 | FromDiscord | <Elegantbeef> Want a string stream that doesn't live on the heap? Good luck |
| 21:31:41 | FromDiscord | <guttural666> RootObj is compiler magic? |

| 22:09:18 | FromDiscord | <Elegantbeef> You don't assign the procs |
| 22:11:56 | FromDiscord | <guttural666> assign the procs? what do you mean |
| 22:12:30 | FromDiscord | <Elegantbeef> You are just instantiating the objects without setting the proc field |
| 22:14:57 | FromDiscord | <guttural666> hmmmmmmm |
| 22:15:49 | FromDiscord | <guttural666> declaring those procs as methods also didn't help, I see |

| 22:40:26 | FromDiscord | <bostonboston> r is an object, so you can use `.` as field accessor or make it the first parameter of a call, in that last line you are accessing the proc `getNextUrl` on the object `r` and then passing `r` to the proc |
