09:25:40PMunchHuh? Looks closed to me
09:26:38PMunchHas anyone created a less copy-intensive strutils?
09:28:06PMunchI'm handling scenarios like a message starting with one or more instances of "\r\n" and then the message. I want to check if the message starts with something. In the strutils module this is `message.strip.startsWith`, but strip returns a new copy of the string..

11:26:41FromDiscord<ieltan> In reply to @kiloneie "Not possible right ?": Nim doesn't support anonymous enums no
11:27:38FromDiscord<ieltan> that `enum` is not concrete so you cannot use it as a object field, you gotta use a Generic and constraint it to an enum
11:29:24FromDiscord<ieltan> sent a code paste, see https://play.nim-lang.org/#pasty=FvtueKqx
11:48:20FromDiscord<fabric.input_output> or make an `ObjKind` enum
11:48:27FromDiscord<fabric.input_output> (edit) "or make an `ObjKind` enum ... " added "type"
12:02:22FromDiscord<kiloneie> that was just me thinking if the above was possible https://media.discordapp.net/attachments/371759389889003532/1295718408259637338/image.png?ex=670fab4d&is=670e59cd&hm=b740d65b53aeb1dbb61f60dcc92811bc4f6247188731d3ad2aaaba9c6f0568fe&
12:03:53FromDiscord<kiloneie> i still wanna have like a NodeType that maps to Object, EmptyNode, etc... i can't remember if that's doable either
12:06:23FromDiscord<kiloneie> probably not as a type, but as a HashSet variable...

13:00:46FromDiscord<odexine> what are you trying to do
13:01:42FromDiscord<odexine> i think mixing generics and inheritance is not that well defined
13:02:27FromDiscord<odexine> sent a code paste, see https://play.nim-lang.org/#pasty=safTTcgJ
13:03:23FromDiscord<odexine> any childobjects you want to be "compatible" with each other must have the same T and K
13:08:59FromDiscord<kiloneie> Well i was just trying to see if something like that is even possible and how it would work. https://media.discordapp.net/attachments/371759389889003532/1295735170829258783/image.png?ex=670fbaea&is=670e696a&hm=c8165ec1cf96591044b560de4882bd4f89bfe33df2562c669064b7487a7f07b8&
13:10:23FromDiscord<kiloneie> Atm i got 2x versions for my system of objects for my game, a "monolithic" one where i use 2x enums in an object with variants, and then a "modular" one where the first enum gets cut in favor of using inheritance instead of it, and then the second enum gets used in the children
13:10:41FromDiscord<kiloneie> so im trying to explore more options
13:11:16FromDiscord<odexine> its still a ref type
13:11:20FromDiscord<odexine> you still have to initialise it
13:11:25FromDiscord<ieltan> ref defaults to nil
13:11:30FromDiscord<kiloneie> oh
13:11:35FromDiscord<odexine> var co = ChildObject[ObjectKind, ImageKind]()
13:11:49FromDiscord<ieltan> So you gotta do `var obj = MyObj()`
13:11:53FromDiscord<ieltan> Beat me to it lol
13:12:02FromDiscord<odexine> butterfingers
13:12:18FromDiscord<ieltan> Idk what that means
13:12:32FromDiscord<odexine> nothing in particular in this case, i just wanted to say it'
13:12:46FromDiscord<ieltan> Oh lol
13:12:48FromDiscord<odexine> technically its to denote someone is a klutz but thats not really my intent
13:12:56FromDiscord<odexine> ~~not like i aint a klutz tho~~
13:15:02FromDiscord<ieltan> In reply to @kiloneie "Atm i got 2x": You mean instead of having a huge enum and matching those in a single object you want distinct objects that have similar base but different features depending on what kind it is?
13:17:34FromDiscord<kiloneie> Monolithic https://media.discordapp.net/attachments/371759389889003532/1295737334586802176/image.png?ex=670fbcee&is=670e6b6e&hm=569b33631212f483d73ba99ad983dd2a2f42e458ddab1bbfc251fce946085622&
13:18:19FromDiscord<kiloneie> Modular https://media.discordapp.net/attachments/371759389889003532/1295737521631793162/image.png?ex=670fbd1a&is=670e6b9a&hm=5a890dc86ad7b53a3849160e9abbf135346fb8adeed3e89a8e219bdaca3723be&
13:19:33FromDiscord<kiloneie> "Modular" allows for well whatever modularity offers and methods/dynamic dispatch if i will use it...↵↵I wanna have a NodeType like in "Monolithic" that maps to the "ObjectKind, ImageKind, AudioKind..."
13:19:43FromDiscord<kiloneie> one way would be via hashSets
13:20:01FromDiscord<kiloneie> at first i was trying to do some nonsense of enum with enum, but that doesn't seem like it's EVER possible
13:20:12FromDiscord<kiloneie> compiler cannot differentiate
13:20:20FromDiscord<kiloneie> between enum and enumerations
13:20:32FromDiscord<ieltan> You already using inheritance you might as well drop the enums and go "full" OOP with `method`
13:21:03FromDiscord<kiloneie> Oh that's an option..
13:21:54FromDiscord<kiloneie> Wait i could just have Node that does nothing, then NodeType that does the same to get the mapping i want... i think...
13:27:40FromDiscord<ieltan> If possible use a "event-oriented" approach, it will allow you to "fire" an event with a particular type (can be your player receiving damage, an enemy dying, etc..). Your event system take care of determining which event was fired and call the appropriate events handler
13:29:17FromDiscord<kiloneie> Got a good source of info on that ?
13:30:10FromDiscord<kiloneie> i am planning to have a level editor and or Game Maker sorts of editor one day in it, and i kind of want to overengineer it now
13:31:00FromDiscord<ieltan> I just know it's a known approach to adopt in game programming, any nim specific thing is a Google away
13:31:13FromDiscord<ieltan> You can ask here too I think chronos made one such system herself

14:01:02FromDiscord<kiloneie> In reply to @ieltan "You already using inheritance": enums demand covering of all cases, therefore you cannot forget to cover the case if you add it, and vice versa

19:42:58FromDiscord<double_spiral> How does one go about converting a seq of strings to a cstringArray
19:44:33FromDiscord<double_spiral> `let c_strings = cast[cstringArray](strings.addr)` seems to segfault when i try to access it
19:45:27FromDiscord<jviega> Take the address of the first element not the top level data structure
19:46:13FromDiscord<double_spiral> Ah
19:46:36FromDiscord<double_spiral> Nope still seqfaults
19:46:38FromDiscord<jviega> Not awesome if there are 0 elements, be careful of that
19:46:40FromDiscord<double_spiral> (edit) "seqfaults" => "segfaults"
19:46:52Amun-RacstringArray is an equivalent of (char *)[]
19:46:55FromDiscord<jviega> No it’ll work if it’s really an array of c strings
19:47:05FromDiscord<double_spiral> is a seq of strings
19:47:09FromDiscord<double_spiral> (edit) "is" => "its"
19:47:20Amun-Ra$cast[cstring](someseq[0].addr)
19:47:27Amun-Raseq must be nil-terminated
19:49:18FromDiscord<Elegantbeef> If it's a `seq[string]` you have to use `allocCstringArray`
19:49:46FromDiscord<jviega> Yeah nim strings aren’t c strings
19:50:08FromDiscord<Elegantbeef> Unless you're passing a single entry of course
19:50:43FromDiscord<heysokam> @double_spiral https://github.com/heysokam/nstd/blob/903b0b6bc837248b859175ea814be00442f75cba/src/nstd/strings.nim#L88-L104
19:50:55FromDiscord<heysokam> thats the idea
19:51:50FromDiscord<heysokam> you dont need the distinct types, as long as your C compiler is not set to be giga-strict
19:55:15FromDiscord<demotomohiro> Nim's string is pointer + size. seq[string] is different from the memory layout of array of pointers to char.
19:58:26FromDiscord<double_spiral> I dont think this is how you spell world https://media.discordapp.net/attachments/371759389889003532/1295838214933839872/image.png?ex=67101ae1&is=670ec961&hm=642660480039d7e064cb51468255ab5ca7568528ef137c4d5f604af0a560e90d&
19:59:11FromDiscord<double_spiral> In reply to @Elegantbeef "If it's a `seq[string]`": This worked btw
19:59:13FromDiscord<jviega> Right because you have nim string objects in that array not c strings, as people have been saying over and over
19:59:52FromDiscord<double_spiral> Take a chill pill
20:04:27FromDiscord<jviega> I’m chill, just recommending you read more closely 🙂
20:05:21FromDiscord<double_spiral> I can recommend the same to you, no when ever mentioned cstrings, i very explicitly said "a seq of strings" 😄
20:05:32FromDiscord<double_spiral> (edit) "when" => "one"

20:24:58FromDiscord<jviega> That’s ambiguous in a way that `seq[string]` is not, which is why the answer qualified it to cstrings, poorly implying you should say if you needed something else 🙂
20:26:24FromDiscord<double_spiral> uhuh its not your fault
20:26:27FromDiscord<double_spiral> god i hate the internet

20:46:23FromDiscord<Elegantbeef> Nah I've pretty much peaked, no one could ever understand me any more
20:46:35FromDiscord<Elegantbeef> Remember to dealloc your cstring array when you're done with it
