00:02:23Araq_ldlework: Rust does the same ... I've never heard that Rust is full of implicit stuff, quite the contrary

00:03:12ldleworkI forgot how much continuous type casting there is in nim

00:43:12ldleworkdom96: its a mixed bag for sure
00:43:22ldleworkCan someone help me write a weighted choice function?
00:45:11ldleworklike lets say I have some sort of mapping structure that maps arbitrary ints to procs
00:45:21ldleworkAnd I want to call a proc randomly based on the associated weights
00:56:46ldleworkCan you have procs as table values?
00:58:17ldleworkdom96: poke
01:06:40dom96Table[string, proc ()] might work
01:06:46dom96I need to go, see you later

01:56:34ldleworkwhy is abs not in the math module?
02:48:52Araq_it's in system.nim
02:51:54ldleworkAraq_: can you help me with some nim thinking?
02:52:18ldleworkwell actually I'm onto something maybe I don't need that
02:52:21Araq_if it can be done in 8 minutes
02:53:03ldleworkhehe dunno, I'll just keep at it
02:59:17ldleworkhmm am I dumb? How do I sort a sequence?
02:59:47ldleworkah, random stdlib module
03:01:28ldleworkI wonder if I can just do values.sort(cmp)

03:03:23ldleworkError: 'initTable' cannot be passed to a procvar
03:03:42ldleworknot sure what that means
03:04:52ldleworkanyone around know how to create a table to procs?
03:05:35ldlework:/
03:06:16ldleworkdef-: you around?
03:06:33Araq_initTable[float, proc()]()
03:06:48Araq_you need to call it. create an issue we can easily improve the error message
03:06:55Araq_and now I have to sleep sorry.

03:23:41ldleworkonionhammer: you around maybe?
03:23:44Araq_ldlework: it's strange, I'm looking at it
03:27:34Araq_ah ok
03:27:56ldleworkphew
03:28:07Araq_ map = initTable[float, proc(diff:float): Color]()
03:28:17Araq_your proc types are incompatible
03:28:28Araq_it needs to have the proper return type
03:28:33Araq_good night.
03:29:53ldleworkthank youuuuu
03:30:45ldleworkit seems strange that it needs the name of the argument to the proc
03:30:47ldleworkie 'diff'

05:50:34ldleworkhow do I iterate over a sequence of generic objects?
05:54:07reactormonkldlework, what's a "generic" object?
05:54:16ldleworkan instance of a generic type
05:54:30ldleworkbut I'm guessing you just do "for i in sequence" and it infers
05:54:32reactormonkWhat do you know about this generic?
05:54:49ldleworkeverything I guess
05:55:16reactormonkWhat does the compiler know about this generic - no constraits, so I assume nothing?
05:57:00ldleworkits just a "type Foo[T] = object attr: T" like thing
06:05:49ldleworkwat, Error: type mismatch: got (typedesc[Biome[getBiomeValue.T]]) but expected 'typedesc[Biome[getBiomeValue.T]]'

06:07:43ldleworkI can paste the whole file if needed
06:08:27reactormonkI don't know, looks good to me.
06:08:34ldlework:(
06:09:26ldleworkreactormonk: I wonder if the parens around the first part of the error means anything
06:09:33ldleworkno idea what that could be though..
06:10:08reactormonkbtw, I'd put the binomes first in the argument list, so you can go binomes.getBinomeValue(x, y)
06:10:23reactormonkalso, [] might be a simpler name here
06:10:23*def- quit (Ping timeout: 264 seconds)
06:10:24ldleworkoh
06:10:33ldleworkreactormonk: what do you mean
06:11:03reactormonkYou could call your method `[]`, so you can binomes[x, y]
06:11:09reactormonk... IIRC that's how it works
06:11:14ldleworkhuh
06:11:37ldleworkwould that be
06:11:51ldleworkbiomes[x,y][Color] ?
06:11:56ldleworksince I need to specify the type?
06:13:01reactormonkI think then you'd have to do binomes.`[]`[Color](x, y)
06:13:10reactormonkbut you don't really need to specify the type
06:15:04ldleworkreactormonk: mind if I gist the file?

18:41:00krux02Araq_: I've problems implementing a getTypeImpl, but getType2 works pretty solid
18:41:49Araq_krux02: yay. now what does that mean?
18:42:33krux02I've tried a lot, but I'haven't found a way, where getTypeImpl, always goes exactly one level deeper
18:42:43*darkf quit (Quit: Leaving)
18:43:25krux02Simple structures work very good, but as far as I define something like this:
18:44:04krux02type MyName = MyGeneric[T], it creates problems
18:44:57krux02A call to getType2 should resolve MyName, if the variable is declared with that name
18:45:12krux02getTypeImpl should return MyGeneric[T]
18:46:30krux02I could make my function work on that case, that it would return MyGeneric, but not without destroying a case that worked so far
18:47:51krux02I've tried a lot, but each fix broke something else in a circulating way
18:49:02krux02 can send you what I've done so far, maybe you can see it better than me, because you are more familiar with the nim type system.
