03:19:22FromDiscord<fl4shk> on second thought, it seems I can't examine generic arguments of a function
03:19:34FromDiscord<fl4shk> wait... I can
03:19:39FromDiscord<fl4shk> I just realized I can
03:20:05FromDiscord<fl4shk> at least, I can do it better when I'm I not tied

03:58:07FromDiscord<fl4shk> it's... possible to do this if a function takes arguments
03:59:28FromDiscord<fl4shk> but I can't see the generics directly

07:12:07FromDiscord<xtrayambak> Is there a way to set the kind of an ADT after it has been allocated using a custom allocation function?
07:19:46FromDiscord<Elegantbeef> I do still love that people call tagged unions ADTs is it's such a pointless term
07:19:47FromDiscord<Elegantbeef> Objects and tuples are by definition ADTs but for some reason they only ever mean tagged unions
07:20:53FromDiscord<xtrayambak> In reply to @Elegantbeef "I do still love": I just call em that because it's a shorthand

07:24:59FromDiscord<Elegantbeef> You have a custom destructor and it's not liking it
07:25:10FromDiscord<xtrayambak> yep, removing the destructor fixes it
07:25:16FromDiscord<Elegantbeef> Also is `MAtom` even right?
07:25:28FromDiscord<xtrayambak> In reply to @Elegantbeef "Also is `MAtom` even": It should be `ptr MAtom`

07:30:15FromDiscord<xtrayambak> No, it isn't Nim, it's my own crappy one I'm writing
07:30:27FromDiscord<Elegantbeef> Did I stutter?
07:33:40FromDiscord<xtrayambak> In reply to @Elegantbeef "Did I stutter?": Haha it isn't due to cycles, it did that because some unrelated pre-VM initialization code tried to allocate using the GC

13:19:39FromDiscord<Robyn [She/Her]> wweird
13:38:38FromDiscord<pmunch> In a Nimble test, is there any way to specify extra command line arguments?
15:06:48FromDiscord<bostonboston> In reply to @pmunch "In a Nimble test,": You can "overload" the test task
15:07:31FromDiscord<bostonboston> https://nim-lang.github.io/nimble/create-packages.html#nimble-test
16:00:37FromDiscord<bostonboston> Alternatively, if you're referring to runtime args and don't mind every test file getting the same args then `nimble test yourArg` passes yourArg as a command line param
16:03:19FromDiscord<pmunch> I didn't want to completely redo the testing system though..
16:03:48FromDiscord<pmunch> Ended up just creating a .nims file with the same name as the test which seems to work fine
16:28:04FromDiscord<firasuke> what's the accepted way to run a proc on program exit? say removing a lock file? does wrapping the entire execution block by `try:` and `finally:` make sense here?
16:29:25FromDiscord<bostonboston> std/exitprocs
16:33:08FromDiscord<firasuke> In reply to @bostonboston "std/exitprocs": does it handle cases where the program might panic or throws an exception?
16:35:08FromDiscord<bostonboston> I don't believe ao
16:35:12FromDiscord<bostonboston> (edit) "ao" => "so"
16:36:01FromDiscord<firasuke> sigh
16:37:00FromDiscord<firasuke> I am trying to create a simple locking mechanism for a program where a lock file is created when the program is run, and the lock file has to be removed when the program exits (be it whether it exits successfully or it throws an exception or if it panics or if it gets interrupted)..
16:41:34FromDiscord<firasuke> would a defer work here?
16:45:46FromDiscord<bostonboston> I don't think it would in all cases, for example of out of mem is raised quit is used, which bypasses all control flow
16:46:21FromDiscord<bostonboston> There is the outofmemhook, but I don't know if there are other weird cases
16:48:35FromDiscord<firasuke> hmm would signal handlers work then?
17:08:27FromDiscord<bostonboston> I can't confidently answer.↵↵Maybe you could make a PR that adds a customer handler to the setTerminate handler in excpt.nim
17:09:04FromDiscord<bostonboston> Custom handler

22:13:06FromDiscord<System64 ~ Flandre Scarlet> Hi! Is there a library that let me serialize (and save to file) stuff with key-value pairs, so I can extend my objects without worrying about versionning please?↵I avoid JSON because values are text.
22:36:45FromDiscord<Elegantbeef> Messagepack or if you're adventurous https://github.com/beef331/vsbf
22:38:59FromDiscord<System64 ~ Flandre Scarlet> In reply to @Elegantbeef "Messagepack or if you're": Does Messagepack let me iterate through values? and writing values individually while keeping key-value pairs?
22:39:35FromDiscord<Elegantbeef> It's practically a binary json variant
22:40:30FromDiscord<System64 ~ Flandre Scarlet> sent a code paste, see https://play.nim-lang.org/#pasty=OyKrTuFY
22:40:58FromDiscord<System64 ~ Flandre Scarlet> I use msgpack4nim
22:43:28FromDiscord<Elegantbeef> vsbf does store the field names in the binary
22:43:39FromDiscord<Elegantbeef> So if that's something you want consider being adventurous and being my first customer
22:46:14FromDiscord<System64 ~ Flandre Scarlet> In reply to @Elegantbeef "So if that's something": Gotta give it a try!↵But what happens if I add a new field to the object and I try to load an old version of this object?
22:46:35FromDiscord<Elegantbeef> It stores the field names so it works just like json
22:47:04FromDiscord<Elegantbeef> It's a versionless format that allows easish migration as fields are typed and you can write hooks for specific types
22:59:44FromDiscord<System64 ~ Flandre Scarlet> In reply to @Elegantbeef "It's a versionless format": I tested quickly, and seems robust and doesn't fail when I add new fields!↵However it seems I can't set a default value up? And how would it act with inheritence?
23:00:12FromDiscord<Elegantbeef> It doesn't work with inheritance as that loses type information
23:00:16FromDiscord<Elegantbeef> "set a default value up"?
23:01:04FromDiscord<System64 ~ Flandre Scarlet> In reply to @Elegantbeef ""set a default value": Yeah↵Because if I add a new field, it is automatically set to 0, but maybe I want something else
23:02:21FromDiscord<Elegantbeef> Can you not just use the type level defaults?
23:02:49FromDiscord<System64 ~ Flandre Scarlet> Nope, doesn't work
23:03:29FromDiscord<Elegantbeef> huh
23:13:16FromDiscord<Elegantbeef> Well thanks, bug found and eliminated
23:13:18FromDiscord<Elegantbeef> https://github.com/beef331/vsbf/blob/master/tests/tbasics.nim#L42-L55 Just to ensure you're doing the same
23:15:43FromDiscord<System64 ~ Flandre Scarlet> In reply to @Elegantbeef "https://github.com/beef331/vsbf/blob/master/tests/t": It works! Thanks!
23:28:36FromDiscord<System64 ~ Flandre Scarlet> However, is it normal that I have vsbf as header and not the type name?
23:31:48FromDiscord<Elegantbeef> Yes
23:32:09FromDiscord<Elegantbeef> I'm uncertain what you mean though, but only the file starts with vsbf
23:32:42FromDiscord<Elegantbeef> The type is a single byte with the last reserved for "type name follows this"
23:33:55FromDiscord<Elegantbeef> So for an `tuple[a, b: int]` you should have like `vsbf Version1 Version0 Struct Int 1 'a' IntValue Int 1 'b' IntValue`
23:34:43FromDiscord<Elegantbeef> If that's not the way the file is written I seemed to have messed up majorly and have no clue how 😄
23:35:09FromDiscord<Elegantbeef> Oh I left out the `StructEnd`
23:35:24FromDiscord<Elegantbeef> That should be the last byte of every vsbf file

23:39:41FromDiscord<fl4shk> can someone tell me how to correctly use `ptr` types in Nim
23:39:52FromDiscord<Elegantbeef> If you need to ask you don't need them
23:40:00FromDiscord<fl4shk> I understand pointers in C++
23:40:03FromDiscord<fl4shk> already
23:40:13FromDiscord<Elegantbeef> Then you understand pointers in Nim

23:40:56FromDiscord<Elegantbeef> You hit a compiler error so you're probably using pointers in the VM
23:41:01FromDiscord<fl4shk> oh gotcha, probably, yeah
23:41:05FromDiscord<fl4shk> these are in macros
23:41:09FromDiscord<Elegantbeef> Use `ref T` instead
