00:38:20FromDiscord<Robyn [She/Her]> In reply to @SmaamX "Any person who worked": I'd recommend trying to follow along with tutorials on YouTube and reading the docs to find what you need
00:38:39FromDiscord<Robyn [She/Her]> also if this is your first time programming, game dev is a huge leap
00:38:51FromDiscord<Robyn [She/Her]> you'd be better off using an engine like Godot
00:51:54FromDiscord<.bobbbob> Is there a good writeup on nim's type inference?

05:18:34*xet7 joined #nim
05:19:06FromDiscord<Elegantbeef> @mjsdev why would you need it?
05:19:28FromDiscord<mjsdev> to parse nim
05:20:05FromDiscord<Elegantbeef> Quote is a compile time construct so it has to be used statically
05:20:43FromDiscord<Elegantbeef> It also doesn't take anything in but a body
05:21:28FromDiscord<Elegantbeef> What are you actually trying to do?
05:25:55FromDiscord<mjsdev> That's a long and complex story. But to try and simplify it, I'm trying to inject code from one file into another.
05:26:13FromDiscord<Elegantbeef> `include`
05:26:26FromDiscord<mjsdev> Not as a file...
05:26:44FromDiscord<Elegantbeef> Make it a template or a generic
05:31:00FromDiscord<mjsdev> sent a code paste, see https://play.nim-lang.org/#pasty=qqcLmzwu
05:31:57FromDiscord<Elegantbeef> Oh goody a class DSL 😄
05:33:21FromDiscord<mjsdev> sent a code paste, see https://play.nim-lang.org/#pasty=DehLfaKk
05:33:46FromDiscord<Elegantbeef> You cannot add fields to types
05:34:12FromDiscord<Elegantbeef> If a type exists it's concrete and cannot be changed
05:34:15FromDiscord<mjsdev> hook is already a field on the Command type
05:34:27FromDiscord<mjsdev> it would be a pointer
05:34:34FromDiscord<Elegantbeef> Ok
05:34:43FromDiscord<mjsdev> in this case to the closure
05:34:45FromDiscord<Elegantbeef> It's best to just write the real Nim you want
05:35:04FromDiscord<Elegantbeef> Instead of making others attempt to comprehend the DSL nonsense and vocab you designed
05:35:28FromDiscord<mjsdev> I'm not making it for others (though they're welcome to use it)
05:36:29FromDiscord<Elegantbeef> Right, but just show the code you want to be made
05:39:35FromDiscord<mjsdev> I'm not sure I follow, the first example is the code I want to be made. I want to be able to add a command to my application in that way. And I wan the "Command" functionality to be similarly defined.
05:39:52FromDiscord<mjsdev> I'll keep playing around. I'm sure there's some way I'm missing.
05:40:57FromDiscord<Elegantbeef> I mean what's your desired macro input to output
05:41:43FromDiscord<Elegantbeef> I found the best way to implement macros is to writeup what you want the user to type then what the macro should generate, this also makes it easier to ask for help as people understand what you're poking at
05:45:46FromDiscord<mjsdev> sent a code paste, see https://play.nim-lang.org/#pasty=lZUFttYI
05:46:19FromDiscord<Elegantbeef> So where are you stuck here?
05:46:49FromDiscord<mjsdev> sent a code paste, see https://play.nim-lang.org/#pasty=gBqKFXmM
05:47:09FromDiscord<mjsdev> It's kinda like meta-meta-programming 😛
05:48:17FromDiscord<mjsdev> By adding the `Hook` facet to the Command, I need to parse and modify the AST defined on its call.
05:48:43FromDiscord<Elegantbeef> This doesn't play too well with Nim's single pass style
05:49:00FromDiscord<mjsdev> (edit) "Command," => "`Command`," | "`Command`,I need to parse and modify the AST defined on its call. ... " added " Then insert that on the other."
05:49:13FromDiscord<Elegantbeef> Cause `Hook` has to add a `hook: ` to `Command` which was declared before `shape` was called
05:50:23FromDiscord<mjsdev> Shape has to add `hook:` to the Command in `Home`
05:50:36FromDiscord<mjsdev> Based on the `Hook` defined on `Command`
05:52:42FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#pasty=sCgmaXqd
05:53:04FromDiscord<mjsdev> I was trying to get away with some casted pointer solution, but ultimately I don't think it's going to work very well since I need the symbol in the target class implementing the command. You can see the current `shape` macro here:↵↵https://github.com/mattsah/mininim-core/blob/main/src/mininim.nim#L110
05:56:20FromDiscord<mjsdev> sent a long message, see https://pasty.ee/SMPFGibb
05:58:49FromDiscord<mjsdev> sent a code paste, see https://play.nim-lang.org/#pasty=UbIkWDEN
05:59:12FromDiscord<Elegantbeef> You can store AST inside of variables or use the macro cache
05:59:48FromDiscord<mjsdev> macro cache might be a good solution... the TypeID stuff I found uses that
06:00:12FromDiscord<Elegantbeef> Yea it's just a compile time table to hold AST so it'll work for forwarding information
06:00:21FromDiscord<Elegantbeef> Though this DSL will cause many headaches
06:00:44FromDiscord<Elegantbeef> Looking like implementing a type symbol but not actually will be the death of you 😄
06:02:33FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#pasty=QoLQLAZY
06:03:28FromDiscord<Elegantbeef> Then you can do a `if not(typeof(builder).getTypeId) != app.builderTypeId: raise (ref ValueError)(msg: "Incorrect pointer conversion")`
06:08:08FromDiscord<mjsdev> I'm not sure I follow that (sorry, still fairly new to Nim, and it's been probably 2 decades since I've worked with statically typed languages and this low level of code)... from the builder standpoint, the issue is effectively that it needs to be generic but I wasn't able to declare a property on an object as a generic function pointer type.
06:08:47FromDiscord<Elegantbeef> Sure, when you add the builder procedure you also store the type information, this can be the `pointer` from `getTypeInfo` or you can use the `getTypeId` 'trick' I showed
06:08:58FromDiscord<Elegantbeef> This allows you to check when you attempt to unpack it to ensure it's the same type
06:09:13FromDiscord<Elegantbeef> Since you still store what it's runtime type was
06:11:59FromDiscord<mjsdev> Does it matter though if the builder type is not explicitly defined though?
06:12:42FromDiscord<Elegantbeef> I can provide an example in a second
06:14:34FromDiscord<mjsdev> OK, appreciate it, as said, sorry if I sound a bit confused. Still very new to this lang and the last time I worked with something like this was C, 20 years ago and it was very unsafe (allowed crazy things to be done).
06:16:41FromDiscord<Elegantbeef> https://play.nim-lang.org/#pasty=qpbfotpd
06:17:04FromDiscord<Elegantbeef> This makes it much safer and prevents attempting to cast a pointer to the wrong proc
06:23:04FromDiscord<mjsdev> I see... firstly, I didn't realize proc was a type like that... secondly though, I'm not sure it works for the style I'm aiming at given it's inlined in the Delegate(builder: ...) style
06:24:15FromDiscord<Elegantbeef> You could make a `typedDecay(myProc)` where `typedDecay` returns the tuple
06:24:30FromDiscord<Elegantbeef> You are doing a lot of shenanigans
06:24:49FromDiscord<Elegantbeef> Is there anyway you could just thunk the procs under a general type
06:25:35FromDiscord<Elegantbeef> Like in my gui I have `proc()` convert to `proc(a: T, b: Y)` where it just wraps it into `proc(a: T, b: Y) = myProc()`
06:32:09FromDiscord<mjsdev> sent a long message, see https://pasty.ee/SYKEfByQ
06:32:34FromDiscord<Elegantbeef> Yes a generic type has to be statically instantiated
06:32:44FromDiscord<mjsdev> I've thought about employing more macros to do some wrapping, but believe it or not, I'm trying to keep that to a minimum
06:32:50FromDiscord<Elegantbeef> You'd need to have a \`Delegate[T]\`\` or whatever
06:33:16FromDiscord<Elegantbeef> Hey I'll judge you deeply for these type macros, but I get it 😄
06:33:49FromDiscord<Elegantbeef> The nicest thing you can probably do is instead of using `T(a: b)` do `T.create((a: b))`
06:33:58FromDiscord<Elegantbeef> Using a tuple and a proc instead of directly creating one
06:34:14FromDiscord<mjsdev> I'm just trying to make an extensible framework with a few core concepts. I know it goes against "the Nim way" probably or the way of any static/safe programming.
06:35:12FromDiscord<Elegantbeef> Heh, it's just odd as I do not see any benefit in the song and dance you're doing
06:35:25FromDiscord<mjsdev> You can read about the basic concepts on the README here: https://github.com/mattsah/mininim -- but basically, classes, shapes (and corresponding facets). Where some Facets (like `Hook`) can add additional common behavior to other facets.
06:35:41FromDiscord<mjsdev> Probably depends on the world you live in.
06:36:58FromDiscord<mjsdev> I live in very fast/frequent (mostly web) app development. I need terse, repeatable patterns and highly modular systems. PHP is my goto, but the type of stuff I'm trying to do here is child's play there given the nature of the language.
06:37:26FromDiscord<mjsdev> If I was building one big application to be maintained for 10 years, I wouldn't reach for solutions like this.
06:38:13FromDiscord<Elegantbeef> You're attempting some very dynamic stuff so it's bound to be an uphill struggle
06:38:30FromDiscord<mjsdev> Indeed, and I expected it... I first tried with Pascal
06:38:57FromDiscord<Elegantbeef> I'd say heavily lean on closures and attempt to cover your basis with a large open door
06:39:02FromDiscord<mjsdev> didn't get very far... then I thought about trying to build my own language, cause I liked Pascal so much: https://github.com/mattsah/pint
06:39:12FromDiscord<Elegantbeef> So practically make all your procedure types `proc(args: JsonNode): JsonNode`
06:39:27FromDiscord<Elegantbeef> `args: varargs[JsonNode]`
06:39:28FromDiscord<mjsdev> Also didn't get very far... I found Nim before that when I was looking for language like or inspired by Pascal
06:39:51FromDiscord<mjsdev> Then decided to take another look.
06:39:58FromDiscord<Elegantbeef> Like I wouldn't even use Nim types for this much dynamism
06:40:16FromDiscord<mjsdev> Yeah, thing with Json nodes is then you just sort of throw away typing altogether
06:40:22FromDiscord<mjsdev> looking for _something_ of a middle ground.
06:40:42FromDiscord<Elegantbeef> Well you need some common window to put everything through
06:40:45FromDiscord<Elegantbeef> So break it down into that window
06:41:39FromDiscord<mjsdev> Yeah, I'll keep ruminating a bit. Not in any super rush. Appreciate the info you have given and I'll keep some of those tricks in mind.
