09:29:09cheatfatedom96, i have found that one more bug with "immediate handle" in acceptAddr -> failAccept() template, on fail it create new future and can cause same error with deep recursion
09:29:49cheatfatecheatfate, question is, is it possible to wait for future but not run exception
09:30:15dom96I still don't understand why these deep recursions happen
09:30:56dom96it is just because `cb` is indirectly calling itself?
09:31:19cheatfatedom96, i will try to make some graphic presentation for you :) wait please

11:29:10*endragor joined #nim
12:14:24endragorIs it possible to refer to template parameter type name from .importcpp pattern? The examples in the manual assume that the type is plainly used in one of the parameters, but it's not the case for me.
12:15:14endragorthe signature is like this:
12:15:14endragorproc doSomething[T](obj: Obj): Container[T]
12:15:41federico3dom96: is there a script to generate a new release?
12:22:50*castlelore quit (Quit: WeeChat 1.4)
12:29:56cheatfatedom96, currently await macro expands to "yield future; future.read" but i think it must be "if not future.finished: yield future; future.read"
12:33:08cheatfatedom96, because when operation completed immediately, future.cb is still nil, so it not called
12:33:14dom96cheatfate: Hrm, I think it should be handled by `cb` https://github.com/nim-lang/Nim/blob/devel/lib/pure/asyncdispatch.nim#L1257

18:09:42ulthanks, but I really want plugins to be written in the Nim too
18:34:43ephjait should be possible

19:07:03ulwow! i guess that using symAddr it is even not needed to keep any table of symbols in the main app which should be filled by the plugin on load; i just need to have reasonable conventions
19:07:29ulanother question is how fast that resolving works
19:07:50uli ask because i want to unload and load again plugin dll from time to time
19:07:56ulbecause it will be recompiled
19:08:35ulif i will just resolve target function by symAddr on every call, will it add huge perf penalty?

19:24:04Motanhey folks, today is my first day with nim (long time python guy looking for something that is slightly more performant and i'm running into this issue)
19:24:06Motanhttp://pastebin.com/EtPLebbk
19:24:29Motani'm guessing i'm missing something subtle, but i can't figure it out
19:25:38Motanif anyone has an idea, copious amounts of punch and pie for all

19:33:08ephjathe BContainer in [BContainer] is not referring the to the type that you created previously
19:35:01*desophos joined #nim
19:35:27ephjabut rather a generic symbol that can be instantiated with any type "proc p[T](x: T): T = x" and then "echo p(1)" or "echo p[int](1)"
19:35:41Motanah
19:35:44Motanso just remove that?
19:36:01Motanbingo, looks like i have a different problem now
19:36:27Motantrying to port https://github.com/peter-the-tea-drinker/nim-MCTS to 0.13.0
19:36:41Motanand i thought i had isolated the issue, maybe i was wrong - but at least it feels like progress
19:36:43ephja[int] can be omitted like in the first instantiation, since it has been implied already with the argument which is of type 'int'
19:36:57federico3Motan: btw are you sure you need methods instead of procs?
19:37:35ephjawere the issues related to generic methods resolved?
19:37:37Motani was trying to isolate the issue, it seems this code was made when a few things were different
19:38:09Motani think so? i'm getting the same issue in the Othello.nim file, going to see if i can reason about what's the actual problem
19:38:18*Motan hands out punch and pie, and party hats
19:39:18*Arrrr quit (Quit: WeeChat 1.4)
19:40:36ephjado you have any carrots?
19:40:50Motanalways
19:40:54*Motan tosses out carrots
19:43:11Motanok, another further question about generics:
19:43:14Motantype is defined as
19:43:16Motan TState* = ref object of RootObj
19:43:25Motan OthelloState* = ref object of TState
19:43:35Motanthe base method is
19:43:36Motanmethod GetMoves[M](state:TState):seq[M] {.base.} =
19:43:49Motanmethod GetMoves*(state: OthelloState):seq[Move] =
19:43:54Motanand that's the "child" method
19:44:03Motanfor some reason it seems they're disassociated
19:44:43Motanit's giving me at least this warning: othello.nim(106, 8) Warning: use {.base.} for base methods; baseless methods are deprecated [UseBase]

19:52:15Motanah, the colon, that's good to remember
19:53:07chrisheller ephja: what errors were you getting with Nimborg?
19:54:59chrishellerI have a Nimborg fork that was up to date with Nim (at least as of a month ago). https://github.com/chrisheller/NimBorg
19:56:16ul============================================================================ GlobalBenchmark relative time/iter iters/s ============================================================================ GlobalBenchmark 435.93ps 2.29G ============================================================================ main.nim relative ti
19:56:17ephjaMotan: "seq[Type]" instantiates 'seq' with 'Type', which does not require a generic parameter to be defined
19:56:34ephjaconsider this: "var x: seq[int]"
19:56:36ulsymAddr 113.17ns 8.84M
19:57:00ulanswering my own question: as think it's fast enough for many use-cases
19:57:25ephjachrisheller: I had to import map from sequtils
19:57:55Motanok
19:57:56ephjaand then I got an ICE with nim devel
19:57:58Motani think i'm understanding
19:59:28chrishellerI fixed the 'undeclared identifier: map' error as well, but haven't triggered any other problems. I should note that we're only using the Python side of Nimborg, not the Lua stuff
20:00:06ephja"proc p(): seq[int] = @[1, 2, 3]"
20:00:29ephjachrisheller: I was testing one of the tests
20:00:35ephjabut I haven't tried the fork
20:01:22chrishellerFeel free to open an issue. I can try to take a look.
20:11:57Motani'm seeing something super weird - the issue seems to go away when I move code around : http://pastebin.com/L75BQy5c
20:12:51Motani guess i need to define all generic perms before defining a proc that uses them?
20:16:50Motandouble strange, if i move the proc above the both declarations it works as well
20:16:54Motanjust doesn't work between them ><
