01:27:54FromDiscord<ElegantBeef> your pragma is before the return type
01:31:22FromDiscord<ElegantBeef> @System64 ~ Flandre Scarlet your bindings are not the same as the internal C code as so things arent working the same causing the issue, what's the output of that tutorial supposed to be?
01:33:15FromDiscord<System64 ~ Flandre Scarlet> sent a code paste, see https://play.nim-lang.org/#ix=3oMy
01:33:45FromDiscord<ElegantBeef> Ah my present output πŸ˜„ https://media.discordapp.net/attachments/371759389889003532/850547912692989972/unknown.png
01:35:12FromDiscord<codic> beautiful
01:36:39FromDiscord<System64 ~ Flandre Scarlet> So we have a problem no?
01:36:48FromDiscord<ElegantBeef> Yes the bindings arent identical it seems
01:37:05FromDiscord<System64 ~ Flandre Scarlet> ah, weird!↡How can I fix that?
01:37:41FromDiscord<ElegantBeef> Well like `setLayer` doesnt have a nilable second parameter but in the example it does
01:41:05FromDiscord<ElegantBeef> `typedef struct Tileset TLN_Tileset;` Like this in the C, i dont get it, there is no Tileset type
01:42:37FromDiscord<System64 ~ Flandre Scarlet> Defined there https://media.discordapp.net/attachments/371759389889003532/850550144075694110/unknown.png
01:42:48FromDiscord<ElegantBeef> In the C
01:43:16FromDiscord<ElegantBeef> It's a `Tileset` which is a pointer to `Tileset` but `Tileset` isnt an existing type that i can see
01:45:37FromDiscord<System64 ~ Flandre Scarlet> ah weird
01:46:11FromDiscord<ElegantBeef> Is that just a ptr to an empty struct, seems so
01:48:10FromDiscord<System64 ~ Flandre Scarlet> WTF↡So what should I do?
01:48:41FromDiscord<ElegantBeef> I'm testing stuf now, i just turned all of those `type Name {.bycopy.} = object` into `type Name = ptr object`
01:48:57FromDiscord<System64 ~ Flandre Scarlet> alright
01:50:05FromDiscord<System64 ~ Flandre Scarlet> sent a code paste, see https://play.nim-lang.org/#ix=3oMC
01:50:22FromDiscord<ElegantBeef> Yea it seems it's just an alias for a ptr to make it more readable

01:55:25FromDiscord<System64 ~ Flandre Scarlet> Oh nice!↡what did you changed to be precise?
01:55:40FromDiscord<ElegantBeef> You have a PR
01:55:54FromDiscord<System64 ~ Flandre Scarlet> Oh alright, I'll accept it
01:56:00FromDiscord<ElegantBeef> I mean https://github.com/system64MC/NimTilengine/pull/1/files
01:56:04FromDiscord<ElegantBeef> The diff is here
01:56:33FromDiscord<ElegantBeef> The important thing might be using `nil` instead of` ""`
01:57:32FromDiscord<ElegantBeef> Nvm it's the ptrs + using `""` instead of nil i guess
01:58:05FromDiscord<System64 ~ Flandre Scarlet> How can I accept a PR please?
01:58:29FromDiscord<ElegantBeef> Should say "Merge PR" or similar here https://github.com/system64MC/NimTilengine/pull/1

06:17:00*bomb-on quit (Remote host closed the connection)
06:17:08FromDiscord<codic> found the issue, it thought that `pid` was a function pointer to posix.fork
06:17:13FromDiscord<codic> because `pid = posix.fork()` works
06:17:19FromDiscord<codic> and the cast was totally doing it wrong lol
06:17:29FromDiscord<codic> ufcs can bite you sometimes
06:19:54FromDiscord<ElegantBeef> Ufcs didnt do it, your usage of a qualified proc call did πŸ˜„
06:21:20FromDiscord<Rika> that was totally not UFCS's fault
06:21:31FromDiscord<codic> hmm
06:21:36FromDiscord<Rika> even if you did something similar in python it would do the same thing
06:22:00FromDiscord<ElegantBeef> well to be fair UFCS/command syntax does mean you can get a proc call without `()`
06:22:07FromDiscord<codic> in an ideal language for me that would error
06:22:09FromDiscord<Rika> only with an argument
06:22:19FromDiscord<Rika> no language with first-class functions would error
06:22:29FromDiscord<codic> (edit) "in an ideal language for me that would error ... " added "right there, the assignment, if I wanted the function pointer I would do x.addr etc"
06:22:31FromDiscord<codic> fair

06:55:53FromDiscord<codic> yep no warnings
06:56:01FromDiscord<codic> but if it is a ref object then I need to bring in `orc`?
06:56:20FromDiscord<Rika> you can mark it as acyclic if you know it is acyclkic
06:59:24FromDiscord<codic> sent a code paste, see https://play.nim-lang.org/#ix=3oO0
07:00:04FromDiscord<Rika> cyclic means a Node that points to itself, or has something that points to itself
07:00:12FromDiscord<Rika> N1 -> N2 -> N1 is cyclic
07:00:16FromDiscord<Rika> a tree is not cyclic
07:00:52FromDiscord<Rika> ref types dont necessarily mean cycles
07:00:59FromDiscord<Rika> just a possibility to
07:01:27FromDiscord<Rika> (and its hard to detect it in some cases i believe)
07:01:29FromDiscord<Rika> which is why you can mark acyclic
07:05:22FromDiscord<ElegantBeef> Yea the compiler doesnt check to make sure it's cyclical, you have to know it's not

07:59:45FromDiscord<Varriount> Anyone know what the practical difference is between `type X = object of Y` and `type X = Y` , assuming `Y` is an object? And would it be different if both X and Y were refs?

08:03:49FromDiscord<Varriount> (I know what they mean semantically, but behavior-wise I'm a bit fuzzy)
08:04:18FromDiscord<ElegantBeef> Well in the first case you can append fields onto the X, it just gets all of Y's, so without added fields it's like `X = distinct Y` afaik
08:06:02FromDiscord<ElegantBeef> Both being refs without added fields is pretty much just an alias afaik, except for methods i guess?

09:21:31FromDiscord<haxscramper> (edit) "usably" => "usable"

10:23:34SebastianMHey guys, Could anyone point me to place where I can find how while is implemented? Thank you
10:25:27FromDiscord<demotomohiro> https://godbolt.org/↡You can see how Nim's while loop compiled to asm
10:25:36FromDiscord<haxscramper> you mean parse/semcheck/codegen?
10:26:09FromDiscord<haxscramper> and there are two really different codegen implementations - for VM (register-based opcodes) and for compilation (direct codegen in C)
10:28:09SebastianMi'm looking through files in nim distribution and can't find it...
10:28:31FromDiscord<haxscramper> which part specifically are interested in?
10:30:51SebastianMhexscramper: Just how does it look. is it a template or macro...

10:31:09FromDiscord<haxscramper> oh, how does it work
10:31:22FromDiscord<haxscramper> https://nim-lang.org/docs/manual.html#statements-and-expressions-while-statement
10:31:30FromDiscord<Varriount> In reply to @SebastianM "i'm looking through files": Do you want to know:↡ - How the compiler represents a while loop internally or↡ - How the compiler generates code for a while loop.
10:31:31FromDiscord<demotomohiro> while is not template or macro
10:31:50FromDiscord<haxscramper> there are no special interactions between `while` and `template/macro`
10:32:08FromDiscord<haxscramper> `while` in macro implementation works the same way as regular code too

11:14:03FromDiscord<haxscramper> Procedure return values must either be used or explicitly discarded via `discard` statement
11:14:29FromDiscord<haxscramper> E.g. `proc test(): SomeType` can be called as `discard test()` or `let a = test()`
11:18:00FromDiscord<Varriount> Or the routine can use the `discardable` pragma.

11:38:41FromDiscord<System64 ~ Flandre Scarlet> oh alright!
11:39:21FromDiscord<System64 ~ Flandre Scarlet> So discard = "I throw the output in the recycle bin" ?
11:42:08FromDiscord<kintrix> discard means you just do not care about a value \:P
11:42:18FromDiscord<kintrix> `discard 1` -> does nothing
11:42:33FromDiscord<kintrix> `discard "Hello World"` -> does nothing as well
11:42:54FromDiscord<kintrix> and if you call a procedure for its side-effects
11:43:03FromDiscord<kintrix> but do not want to store its return value
11:43:19FromDiscord<kintrix> you can just `discard procedureWithSideEffects()`
11:44:30FromDiscord<kintrix> so it literally just does nothing

14:42:02FromDiscord<System64 ~ Flandre Scarlet> it's SDL's "fault" so
14:42:09FromDiscord<Rika> worry once you hit a few hundred πŸ˜›
14:43:41FromDiscord<System64 ~ Flandre Scarlet> Yeah lol, it will be hard
14:44:06FromDiscord<System64 ~ Flandre Scarlet> but I'm more worried about 2 things
14:44:34FromDiscord<Rika> ? which
14:44:48FromDiscord<System64 ~ Flandre Scarlet> when I call a C proc I have to put myVar.cint, is there a way to avoid puttinc cint? https://media.discordapp.net/attachments/371759389889003532/850746984113504276/unknown.png
14:46:19FromDiscord<haxscramper> you can write a wrapper that uses `int` argument
14:46:37FromDiscord<haxscramper> Additional layer of indirection on top of raw C bindings
14:47:12FromDiscord<haxscramper> You can also clean up names, remove `cint` return value etc.
14:47:27FromDiscord<System64 ~ Flandre Scarlet> that may cause problems no?
14:47:36FromDiscord<haxscramper> For example `proc setLayerPosition(a,b,c: int) = discard tLN_SetLayerPosition(a,b,c)`
14:47:44FromDiscord<haxscramper> In reply to @System64 "that may cause problems": What kind of problems?
14:48:02FromDiscord<System64 ~ Flandre Scarlet> when passed to the dll
14:48:48FromDiscord<haxscramper> I'm not sure if I follow. You just define helper proc with more convenient interface, that's all.
14:49:02FromDiscord<System64 ~ Flandre Scarlet> ah alright
14:49:49FromDiscord<System64 ~ Flandre Scarlet> sent a code paste, see https://play.nim-lang.org/#ix=3oPZ
14:52:12FromDiscord<haxscramper> sent a code paste, see https://play.nim-lang.org/#ix=3oQ1
14:53:01FromDiscord<haxscramper> Technically this is not different from wrapping procedure as `int` argument in the first place, but this might cause problems in edge cases anyway, because nim `int` is not guaranteed to be the same as C's `int`
14:53:07FromDiscord<haxscramper> `cint` does have this guarantee
14:53:28FromDiscord<haxscramper> Not that it really matters for the most case, but I do prefer to be explicit about what I wrap and how it is called
14:53:51FromDiscord<System64 ~ Flandre Scarlet> is there a way to auto transtype to cint ?
14:54:31FromDiscord<Rika> its not ideal
14:54:39FromDiscord<haxscramper> Yes, though I woudl advise aginst implicit type conversions. The distinction is there for a reason
14:54:40FromDiscord<Rika> you can, but its not recommended
14:54:58FromDiscord<System64 ~ Flandre Scarlet> okay so I won't do that so
14:55:16FromDiscord<System64 ~ Flandre Scarlet> and it's just a .cint thing, not a lot of work lol
14:55:34FromDiscord<Rika> ive never heard of it
14:55:34FromDiscord<Rika> sent a code paste, see https://paste.rs/Itx
14:55:41FromDiscord<haxscramper> I meant `inline`
14:55:46FromDiscord<Rika> lol
14:55:47FromDiscord<Rika> okay
14:56:03FromDiscord<System64 ~ Flandre Scarlet> and making it auto-discard if not saved in a variable?
14:56:26FromDiscord<Rika> not recommended either
14:56:36FromDiscord<kintrix> You can just remove `discard`, then↡And give it a return value
14:56:42FromDiscord<haxscramper> ideally I woudl check return codes and `raise` on invalid ones
14:56:57FromDiscord<haxscramper> Because we do have exceptions so
14:56:57FromDiscord<kintrix> In reply to @kintrix "You can just remove": oh wait...↡I misunderstood the question πŸ˜…
14:56:59FromDiscord<System64 ~ Flandre Scarlet> I just want auto-discard some procs that returns a bool
14:57:20FromDiscord<Rika> auto-discard is really not recommended ever
14:57:23FromDiscord<kintrix> yep
14:57:28FromDiscord<haxscramper> Again - they return `bool` for a reason, so you might not want to just discard everything
14:57:33FromDiscord<kintrix> discard is needed for a reason
14:57:55FromDiscord<haxscramper> Because you will be throwing again potential error indications that must not be ignored
14:58:18FromDiscord<haxscramper> it returns `0` for "ok" and `1` for "not ok"?
14:58:49FromDiscord<System64 ~ Flandre Scarlet> the thing is in a lot of programming language, some functions return true or false to say if it ran well or not, but often used for tests↡So I can use a bool function like a void funtion
14:59:18FromDiscord<haxscramper> It depends on the API
14:59:25FromDiscord<haxscramper> OF the particular library and particular function
15:00:01FromDiscord<System64 ~ Flandre Scarlet> That returns a bool but it's used as a void function in the C demo https://media.discordapp.net/attachments/371759389889003532/850750815311233035/unknown.png
15:00:51FromDiscord<Rika> then convert the "raw function" into a function that returns void but raises when the raw function returns false
15:01:02FromDiscord<Rika> convert -> create a wrapper for
15:01:15FromDiscord<haxscramper> https://github.com/megamarc/SuperMarioClone/blob/e36e54612c6075034c007350617cd185486ec458/Tilengine.cs#L978 C# wrappers seem to treat return value for this function as success code

15:02:20FromDiscord<System64 ~ Flandre Scarlet> sent a code paste, see https://play.nim-lang.org/#ix=3oQi
15:02:34FromDiscord<Rika> nim is not c
15:02:56FromDiscord<System64 ~ Flandre Scarlet> so I guess it's better to Discard manually
15:03:16FromDiscord<Rika> either discard manually or as ive said make a wrapper function that doesnt return anything but raises
15:03:17FromDiscord<haxscramper> no, the best way is to chec & raise in additional wrapper
15:04:03FromDiscord<System64 ~ Flandre Scarlet> what does raises means?
15:04:22FromDiscord<Rika> exception raising
15:04:24FromDiscord<kintrix> It's also called throwing an error
15:04:28FromDiscord<kintrix> in many languages
15:04:56FromDiscord<System64 ~ Flandre Scarlet> Aaah yeah exception

15:41:38FromDiscord<Rika> can you show the definition of TLN_Input
15:41:49FromDiscord<haxscramper> btw you don't have to write `tLN_Init`, `tlnInit` will work fine too

20:31:12FromDiscord<ElegantBeef> Yah that aswell
20:31:51FromDiscord<System64 ~ Flandre Scarlet> In reply to @ElegantBeef "Also someone actually using": I read Nim supports that so I do it lol
20:32:02FromDiscord<System64 ~ Flandre Scarlet> In reply to @ElegantBeef "Your proc doesnt have": You mean the raster proc?
20:33:08FromDiscord<ElegantBeef> yes
20:33:23FromDiscord<ElegantBeef> Read the error, type mismatch, it expects a `proc(cint){.cdecl.}`

20:34:27FromDiscord<System64 ~ Flandre Scarlet> It says invalid pragma https://media.discordapp.net/attachments/371759389889003532/850834978459746304/unknown.png
20:34:46FromDiscord<ElegantBeef> Cause you added it to the stmtlist and not the procedure `proc raster(lin: cint){.cdecl.}`
20:35:34FromDiscord<haxscramper> God, this formatting
20:36:24FromDiscord<ElegantBeef> Like i suggest you should remove `tln` from all procedures/type names to make your life easier
20:37:06FromDiscord<System64 ~ Flandre Scarlet> yeah I should do that
20:40:24FromDiscord<System64 ~ Flandre Scarlet> Nice! https://media.discordapp.net/attachments/371759389889003532/850836477658660874/unknown.png

21:40:52ForumUpdaterBotNew thread by Mantielero: UPlot - plotting library, see https://forum.nim-lang.org/t/8089
21:49:34FromDiscord<codic> how do I create and detach a thread in Nim?

21:55:32*burn quit (Remote host closed the connection)
21:57:10FromDiscord<ElegantBeef> I believe threads are started detached if i understand what that does properly, so simply make a proc annotated with `{.thread.}` and do `creatThread` with it

22:12:52*FisHlaBsoMAN-t8 quit (Remote host closed the connection)
22:17:45FromDiscord<codic> and after createThread do I have to do something special to detach it or should I consider it detached? (i.e. I never have to join it)
22:19:29FromDiscord<codic> oh I just read what you wrote
22:22:08FromDiscord<codic> what's the first parameter of createThread?
22:39:47FromDiscord<ElegantBeef> A generic `Thread[T]` where T is your thread proc's input parameter
22:39:52FromDiscord<ElegantBeef> (edit) "`Thread[T]`" => "`var Thread[T]`"
22:41:25FromDiscord<ElegantBeef> @codic https://nim-lang.org/docs/threads.html#examples does show the basics of using threads/locks
22:42:30FromDiscord<codic> looks to work

22:48:00ForumUpdaterBotNew Nimble package! redismodules - A new awesome nimble package, see https://github.com/luisacosta828/redismodules
22:51:52FromDiscord<brainproxy> Just getting started with Nim macros, have implemented a couple successfully that really helped cut down on some boilerplate, fun stuff.↡↡I'm writing one currently that I want to use as a pragma, and I need it to support arguments, which of course pragmas can, but I'm wondering about default values for parameters. Is it possible somehow?
22:54:31PMunchShould be possible
22:54:37PMunchWorst case scenario you can create a template
22:55:28FromDiscord<ElegantBeef> Well it's not exactly possible to have default parameters afaik, since you probably want them to be static
22:56:16FromDiscord<ElegantBeef> Is how i handle parameters https://github.com/beef331/kashae/blob/master/src/kashae.nim#L204-L220
22:56:32FromDiscord<brainproxy> sent a code paste, see https://play.nim-lang.org/#ix=3oT2
22:57:31FromDiscord<brainproxy> but interestingly, the passed `body` ends up being slightly different if you print with `treeRepr body` than if you use the `foo` that takes 3 arguments.
22:57:53FromDiscord<brainproxy> In reply to @ElegantBeef "Is how i handle": looking
22:57:54FromDiscord<ElegantBeef> I believe it gets typed in that case which is odd but what happens
23:00:06FromDiscord<brainproxy> so using your approach the "gets typed" doesn't happen?
23:02:09FromDiscord<ElegantBeef> If you're getting `sym`s yea it will not happen
23:06:22FromDiscord<System64 ~ Flandre Scarlet> Nim doesn't have the Double type?
23:06:27FromDiscord<ElegantBeef> float64
23:06:46FromDiscord<System64 ~ Flandre Scarlet> it's double?
23:06:59FromDiscord<ElegantBeef> It's 64 bits which is what most languages that have double call doubles
23:07:18FromDiscord<System64 ~ Flandre Scarlet> Oh I see
23:16:57FromDiscord<System64 ~ Flandre Scarlet> btw, is it possible to make a Nimble plugin?
23:20:25FromDiscord<ElegantBeef> plugin?
23:24:31FromDiscord<LuKol> In reply to @System64 "btw, is it possible": do you mean library which you include to your program?
23:25:36FromDiscord<System64 ~ Flandre Scarlet> yeah my Tilengine binding
23:26:10FromDiscord<ElegantBeef> Well you make a nimble package throw it on github and you're golden to just `requires "https://github.com/name/repo"`
23:26:49FromDiscord<System64 ~ Flandre Scarlet> Oh I see
23:27:18FromDiscord<System64 ~ Flandre Scarlet> I want to make a binding for GameMusicEmu too
23:29:06FromDiscord<ElegantBeef> Yea well you still havent finished the tilengine bindings imo πŸ˜›
23:29:27FromDiscord<System64 ~ Flandre Scarlet> yeah I have to cleanup the TLN_xxx thing
23:29:48FromDiscord<ElegantBeef> Remove that barbaric `tln` and add some helper functions for ints -> cints (or if lazy converters)
23:30:40*fputs quit (Remote host closed the connection)
23:31:20FromDiscord<ElegantBeef> I do have to ask, how'd you find nim, games from scratch?
23:31:35FromDiscord<System64 ~ Flandre Scarlet> In reply to @ElegantBeef "I do have to": Yeah
23:34:06FromDiscord<ElegantBeef> Ah nice, now just if you stick around and write idiomatic code πŸ˜›
23:36:19FromDiscord<System64 ~ Flandre Scarlet> I didn't understood very well there
23:36:54FromDiscord<ElegantBeef> Joking about using `: void` and `()` for bracing logic
23:37:23FromDiscord<System64 ~ Flandre Scarlet> aaaah yeah lol↡I comes from the Java World lol
23:39:27FromDiscord<System64 ~ Flandre Scarlet> But aren't the TLN_ prefix supposed to indicate it comes from Tilengine?
23:39:46*fputs joined #nim
23:39:55FromDiscord<ElegantBeef> That's not a concern in Nim
23:40:15FromDiscord<LuKol> In reply to @ElegantBeef "I do have to": looking for alternative to python with compilation possibility
23:40:16FromDiscord<ElegantBeef> It doesnt care about where symbols come from just that they're imported πŸ˜„
23:41:09FromDiscord<ElegantBeef> It makes the UFCS much nicer without it
23:41:16FromDiscord<LuKol> only thing i cannot learn properly is whitespace instead of brackets
23:41:20FromDiscord<System64 ~ Flandre Scarlet> UFCS?
23:41:32FromDiscord<ElegantBeef> https://nim-lang.org/docs/manual.html#procedures-method-call-syntax
23:43:24FromDiscord<System64 ~ Flandre Scarlet> ah yeah so I can do Tilengine.aProc instead of Tilengine.TLN_aProc?
23:43:28FromDiscord<ElegantBeef> Yes
23:43:37FromDiscord<System64 ~ Flandre Scarlet> yeah seems it's much cleaner
23:43:38FromDiscord<ElegantBeef> But generally that's only used for ambigious calls
23:43:50FromDiscord<ElegantBeef> Normally you just do `aProc`
23:43:58FromDiscord<System64 ~ Flandre Scarlet> yeah with import
23:44:33FromDiscord<System64 ~ Flandre Scarlet> I dunno why, but VS Code doesn't display all possibilities
23:44:44FromDiscord<ElegantBeef> What do you mean "all possibillities"?
