| 00:11:44 | FromGitter | <jrfondren> so asyncstreams.read works by assigning the stream callback so that the next write() will complete the future that .read is now returning. |

| 00:14:54 | FromGitter | <jrfondren> @dirsuptek there you go. see, it's not a bug at all. your read is handled immediately by which I mean soon. |
| 00:16:06 | FromGitter | <jrfondren> the 'soon' isn't 500ms later. it's actually pretty close to immediately after. but there's always a poll() after the 'soon'. |

| 01:01:29 | FromDiscord | <Avatarfighter> Stupid question, how do you make a table hold any type as a value? |
| 01:06:44 | FromGitter | <jrfondren> you can't. |
| 01:07:25 | FromGitter | <jrfondren> what you can do instead is define a variant type AnyType and then make that your value, which means runtime checking every time you fetch a value to see what its actual type is. |
| 01:07:45 | FromGitter | <jrfondren> I believe there are some packages in nimble that provide an AnyType that might be more convenient |
| 01:08:20 | FromGitter | <jrfondren> ... I don't remember what it's called. I saw it in passing. |
| 01:08:51 | FromGitter | <jrfondren> if your actual need is to have one of a small set of types, your own variant will be easy |
| 01:09:34 | FromDiscord | <Avatarfighter> Yeah I just need to handle a specific set of types, I just don't know what or how I should make an "AnyType" |
| 01:10:01 | FromGitter | <jrfondren> alright one sec |
| 01:10:05 | FromGitter | <kayabaNerve> Inheritance. |
| 01:10:18 | FromGitter | <kayabaNerve> type x = ref object of RootObj |
| 01:10:28 | FromGitter | <kayabaNerve> type y = ref object of x |
| 01:10:55 | FromGitter | <kayabaNerve> Add an enum of possible types, save a value from there to X, cast as needed |
| 01:12:14 | FromDiscord | <Avatarfighter> huh, I'll try that |
| 01:13:03 | FromDiscord | <Avatarfighter> Thank you 😃 |
| 01:14:18 | FromGitter | <jrfondren> ah if only Nim dispatched off return types as well as parameter types, like Ada. |
| 01:14:50 | FromGitter | <jrfondren> ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=5cdcb98ada34620ff94b7bf0] |
| 01:14:53 | FromGitter | <jrfondren> then that would actually work :p |
| 01:18:19 | FromGitter | <jrfondren> this is what I was talking about: https://gist.github.com/jrfondren/44fb942087502336eac4c9e5471e729c |
| 01:19:58 | FromDiscord | <Avatarfighter> That seems pretty straightforward, I just need to rewrite some stuff to handle this kind of thing, i'm ngl i'm pretty excited for when i put all this code together \:). Thank you jrfondren |
| 01:31:29 | FromGitter | <jrfondren> #11263 created for that async stuff. |
| 01:53:54 | FromGitter | <kayabaNerve> A case statement doesn't allow named subtypes |
| 01:54:07 | FromGitter | <kayabaNerve> It is cast-less though |
| 01:54:18 | FromGitter | <kayabaNerve> And a Generic doesn't preserve the master type |

| 06:43:45 | PMunch | Okay, trying to deploy the new playground now :) |
| 06:44:01 | leorize | rayman22201: try passing --passC:'-g' |
| 06:44:24 | leorize | maybe debuginfo have to be embedded into the resulting object files? |
| 06:45:35 | PMunch | Hmm, devel doesnt seem to build atm.. |
| 06:46:59 | leorize | PMunch: I saw localhost in the frontend code :P |
| 06:47:21 | PMunch | Oh right, good catch! |
| 06:48:15 | leorize | you should really store it in a const |
| 06:49:07 | leorize | narimiran: just made a new feature that should reduce the amount of nimsuggest instance running, would you like to take a testdrive? |
| 06:49:39 | narimiran | leorize: of course :) |
| 06:50:19 | narimiran | and i don't know how often does it crash |
| 06:50:44 | PMunch | leorize, well in production it should just use relative URLs |
| 06:50:54 | PMunch | But that didn't work when I opened it as a file in my browser |
| 06:51:02 | leorize | narimiran: see :messages and count the number of "exited with error code 1" :P |
| 06:51:07 | leorize | PMunch: use jester :) |
| 06:51:13 | leorize | serve it with jester :P |
| 06:51:18 | PMunch | That's what the actual server does |
| 06:51:24 | PMunch | I was just lazy while testing this :P |
| 06:51:30 | leorize | :P |
| 06:51:44 | PMunch | I even had the jester instance running locally, it would've just been a matter of moving the files over |
| 06:52:27 | leorize | laziness strikes |
| 06:52:45 | leorize | narimiran: please checkout the session-resume branch of nim.nvim |
| 06:53:22 | leorize | this should attempts to revive nimsuggest when it dies instead of spawning a new one at the current location |
| 06:53:28 | narimiran | leorize: ok, and what am i looking for? just count open nimsuggest instances? |
| 06:54:13 | leorize | yea, it should only use 1 per project |

| 07:04:50 | PMunch | Since I couldn't build devel through choosenim (and Karax needs devel ATM) I manually installed the new frontend in a directory if anyone wants to try it https://play.nim-lang.org/newfrontend/index.html |
| 07:05:53 | leorize | nice, but you should try hiding the index.html part :) |
| 07:06:00 | PMunch | And the link format has changed, so a tour is now linked to like this: https://play.nim-lang.org/newfrontend/index.html#tour=https://play.nim-lang.org/tours/example.html |
| 07:06:52 | PMunch | leorize, that's just because I manually put in there, you can go to: https://play.nim-lang.org/newfrontend/ as well |

| 07:11:43 | leorize | now the only cool thing left that the playground needs is output streaming from the server |
| 07:12:10 | PMunch | Hmm, yeah |
| 07:12:43 | PMunch | That's a tricky one though.. |
| 07:12:48 | leorize | after that you can even go further and implements terminal emulation :D |
| 07:13:21 | PMunch | Let's not get too carried away here :P |
| 07:14:56 | leorize | I think you could use websockets for data streaming? |

| 07:25:51 | narimiran | leorize: i have tested it. when i'm careful which file i open first, it is just one instance of nimsuggest, but: |
| 07:26:34 | narimiran | ...if i save a session with multiple windows and buffers, and then i do `nvim -S`, i immediately get multiple nimsuggests |
| 07:28:04 | leorize | that's a feature I don't use... |
| 07:28:13 | leorize | I'll try to think of a way to combat that |
| 07:28:35 | narimiran | well i guess it is the same if i manually open multiple files in "wrong order" |
| 07:28:52 | leorize | well there aren't any easy way to detect a project :P |
| 07:29:16 | narimiran | .nimble file? |
| 07:29:58 | leorize | walking directories is a synchronous operation, so with the rate of nimsuggest dying this is not a nice choice |

| 07:32:01 | leorize | narimiran: ofc, you could try to extend `nimble path` to return the path to the project file :) |
| 07:32:16 | leorize | also it should work everywhere within the project |

| 07:34:33 | leorize | use :call nim#suggest#ProjectStop() |
| 07:34:43 | leorize | or else the session resume feature will just resurrect them |

| 09:25:14 | * | ftsf joined #nim |
| 09:25:28 | Zevv | interesting that it didn't pop up earlier and there were no tests for it, it feels like a very obvious thing |
| 09:25:38 | Zevv | but noone ran into it |
| 09:25:50 | Araq | I'm sure it was reported before |
| 09:26:05 | Araq | but it's also un-generic programming aka bad style |
| 09:26:54 | Araq | why would you specialize stuff like that? it means your generic T is not valid for string |
| 09:28:07 | FromGitter | <alehander42> well it's a form of overloading |
| 09:28:29 | * | Gertm left #nim ("Leaving") |
| 09:28:49 | Araq | that's just a word, if you want to specialize the implementation there are two reasons for this: |
| 09:29:18 | Araq | 1. it doesn't do the right thing for 'string' |
| 09:29:28 | Araq | if so, better use [T: not string] |
| 09:29:38 | Araq | 2. you think you can optimize it |
| 09:30:06 | Araq | if so, better use a 'when' statement in the generic it's clearer than misusing the overload resolution mechanism for it |
| 09:30:22 | FromGitter | <alehander42> yeah, but what if you have many cases: string, int etc |
| 09:30:41 | Araq | then you don't have a "generic" implementation |
| 09:30:41 | FromGitter | <alehander42> can you even write not about them |
| 09:30:55 | FromGitter | <alehander42> but you can still have a default for the other types |
| 09:32:29 | Araq | well please tell me about a valid use case, I'm not seeing it |
| 09:34:24 | Araq | remember that the specialization of vector<bool> in C++ is now widely regarded as a mistake |

| 09:45:19 | PMunch | Well nim has the --app:gui to hide the console |
| 09:45:29 | PMunch | Not sure if that applies to scripts called by the program though.. |

| 10:41:40 | PMunch | Hmm, anyone have any good phone recommendations? |
| 10:41:58 | PMunch | My trusty OnePlus One is starting to show its age.. |
| 10:42:35 | PMunch | Probably didn't help that I dropped it in the sink under running water yesterday so I had to take the entire thing apart to get the speaker (and hence my alarm) to work again.. |

| 10:45:17 | FromGitter | <kaushalmodi> I loved my OnePlus One too, which coincidentally, I lost to water as well .. I went swimming with my son with the phone in my swim shorts |
| 10:45:40 | clyybber | pocophone f1, though you might want to flash lineage on it |

| 10:47:13 | * | laaron joined #nim |
| 10:48:16 | PMunch | Hmm, the Pixel 3 lacks a mini-jack and has a smallish battery.. |
| 10:48:47 | PMunch | The Pocophone has such a huge notch though.. |
| 10:49:03 | PMunch | I wish they'd just remake the One with better internal specs.. |
| 10:49:54 | PMunch | The grippy texture on the back is great, battery life is great (at least when it was new), and the flash anything and stay within warrenty was cool (not that I ever used it) |
| 10:56:57 | PMunch | Hmm, the Pocophone looks nice |
| 10:57:12 | PMunch | Spec-wise |

| 11:23:52 | FromGitter | <kaushalmodi> Ref: https://github.com/nc-x/crafty/pull/1 |
| 11:24:31 | FromGitter | <kaushalmodi> Apparently, they are style-insensitive on Windows, but case-sensitive on Linux |
| 11:25:12 | FromGitter | <kaushalmodi> Araq: please see above question about package identifier case-sensitivity on Linux. |
| 11:25:57 | * | gangstacat joined #nim |
| 11:26:19 | narimiran | kaushalmodi it is known |

| 11:30:30 | PMunch | Zevv, if I were to get a Planet phone I think I'll hold off for the Cosmo: https://www.indiegogo.com/projects/cosmo-communicator#/ |
| 11:34:41 | Zevv | makes sense. I'm still pretty heppy with the gemini, only thing is the camera is barely usable |
| 11:37:08 | Araq | kaushalmodi: on Unix we attempt the module name as you wrote it followed by trying it in alllowercase |
| 11:38:45 | Araq | by the convention is snake_case_everywhere.nim |

| 11:51:04 | PMunch | I have a fairly solid grasp on both Nim and threads in C, but threads in Nim still confuses me.. |
| 11:51:09 | Araq | kaushalmodi: I don't care what the internet thinks about Windows vs Linux, I know enough of both systems to have an informed opinion on my own |
| 11:51:46 | PMunch | Zevv, neat. Isn't it a bit big though? And do you actually use the keyboard and/or linux on it? |
| 11:52:36 | Araq | PMunch, threading in Nim is pretty simple, you use createThread on global vars and you use channels as global vars for communication. everything else pretty much doesn't work |
| 11:52:45 | Araq | :D |
| 11:53:38 | Araq | but hey, it's a lovely shared-nothing architecture that SCALES (TM) (better never benchmark anything though) |
| 11:54:37 | PMunch | Haha, yeah I've done a thing or two with threads in Nim. But they just seem odd to use, I always feel like I'm doing it wrong |
| 11:55:27 | Araq | that's good, I also planned a compiler switch --verify to give you move of this feeling |
| 11:55:55 | FromGitter | <kaushalmodi> Araq: It's not about opinion; I'm genuinely curious how other languages deal with symlinks |
| 11:56:15 | Araq | --verify would verify your code automatically, it's pretty simple, the compiler would always say "I am sorry, I cannot compile this Dave, it has a bug somewhere" |
| 11:56:37 | FromGitter | <kaushalmodi> I can see myself creating a similar issue like that symlink support issue. |
| 11:56:41 | livcd | kaushalmodi: is not that an old gh issue ? |
| 11:56:50 | FromGitter | <kaushalmodi> Yes, it is |
| 11:57:17 | FromGitter | <kaushalmodi> Talking about that because it surfaced in a lobste.rs thread |

| 12:02:09 | clyybber | kaushalmodi: Fix it :) shouldn't be too hard |
| 12:04:40 | Araq | before you "fix" it, create a good test case for it |
| 12:05:02 | Araq | extra points when I can still checkout the tests/ directory on Windows |
| 12:06:15 | Araq | extra points if I can later on still *add* new test files on Windows |

| 12:18:47 | FromGitter | <kaushalmodi> The first step would be to create that issue again so that we can track it. While I not be capable to fix this myself, I will attempt to investigate which part of the stdlib is causing this. |
| 12:19:39 | Araq | for me the bug report was a cry for medical help. |
| 12:20:29 | FromGitter | <jrfondren> as in, "Doctor, when I do this, it hurts" ? |
| 12:20:37 | Zevv | "don't do that" |

| 12:53:55 | clyybber | Araq: Should I make "var a = @[1]" generate "var a; var tmp = @[1]; `=move`(a, tmp)" or just a simple assignment? |
| 12:55:43 | * | sacredfrog joined #nim |
| 12:56:58 | clyybber | because previously, it was apparently mapped to "var a; `=sink`(a, @[1])" |
| 12:59:36 | Araq | what would the "simple assignment" be? keep in mind that the assignment can be in a loop and then you need to free the old seq |
| 13:02:27 | clyybber | hmm, yeah. The problem rn is that seq literals are NIM_CONST in the generated C code, so are generating segfaults upon trying to move. |
| 13:04:16 | FromGitter | <mratsim> sometimes I'd like to have a seq be materialized in the BSS segment of the binary. When I'm usin them for table implementations of transcendatal functions like exponential or logarithm. |
| 13:04:26 | FromGitter | <mratsim> const seq* |
| 13:04:50 | FromGitter | <mratsim> right now I'm forced to use `var` and I can't use no-sideeffect/func |
| 13:05:47 | FromGitter | <alehander42> but why can't you use a const array |
| 13:05:55 | FromGitter | <alehander42> const seq cant change, right? |
| 13:09:38 | FromGitter | <jrfondren> a seq needs an accumulator. that's a pointer though so it could be 0, so you could have a const seq. |
| 13:09:55 | FromGitter | <mratsim> it's the same. const array/seq only exist in the VM and have no address |
| 13:10:12 | * | cyberjpn joined #nim |
| 13:10:22 | FromGitter | <mratsim> if you index them, the compiler will directly inline the value needed |
| 13:10:37 | FromGitter | <jrfondren> ah, different problem. |
| 13:11:09 | FromGitter | <mratsim> See: https://github.com/numforge/laser/blob/master/laser/primitives/simd_math/exp_log_common.nim#L40-L46 |
| 13:11:59 | FromGitter | <mratsim> And it's used there: https://github.com/numforge/laser/blob/master/laser/primitives/simd_math/exp_log_avx512.nim#L62 |
| 13:12:18 | FromGitter | <mratsim> but the proc can't be noSideEffect due to accessing a global var :/ |
| 13:12:36 | FromGitter | <mratsim> it's just a small issue anyway. |
| 13:17:41 | FromGitter | <jrfondren> maybe `func getx: int = {.gcsafe.}: x` should work. |
| 13:17:56 | FromGitter | <mratsim> ah yeah, right |
| 13:18:04 | FromGitter | <jrfondren> it doesn't now |
| 13:18:58 | FromGitter | <mratsim> well since this will be mostly used in an OpenMP multithreaded context, and OpenMP proc cannot be noSideEffect, ultimately it's fine. |
| 13:19:12 | FromGitter | <jrfondren> I guess noSideEffects is the stronger guarantee so that shouldn't work in general, but it could at least work in the case where the only side effects are global variable accesses |
| 13:20:16 | Araq | you can use a {.noSideEffect.}: block in devel |
| 13:21:17 | FromGitter | <mratsim> yipeeh! :p |

| 13:25:48 | FromGitter | <jrfondren> I don't think so, but I haven't checked for sure. What commands are you wanting to run? |
| 13:26:12 | Zevv | enthus1ast: the problem is that you can not rely on shell commands if someone does your nimble thing on windows |
| 13:26:25 | enthus1ast | "git submodule init" and "git submodule update" |
| 13:26:26 | FromGitter | <jrfondren> depending on what you need to do, for a library, you might have an {.error.} at compile-time to warn the user to do something |

| 13:27:13 | enthus1ast | it seems that "after install:" does what i want |

| 13:27:57 | enthus1ast | ? |
| 13:28:33 | enthus1ast | too much slang for me :D |
| 13:28:37 | FromGitter | <jrfondren> I would surprised if "after install" does what you want because on install, most of your repo has already been discarded by nim |
| 13:28:52 | FromGitter | <jrfondren> *by nimble |
| 13:29:42 | enthus1ast | the thing is, this is an installer for an internal webchat that is divided into multiple submodules. Most of the public functionality is done in submodules. |
| 13:29:48 | * | sacredfrog joined #nim |
| 13:29:52 | FromGitter | <jrfondren> maybe nimble should --recurse-submodules when it does a git clone, instead |
| 13:30:24 | FromGitter | <jrfondren> yeah, all I know about git submodules is that they steal candy from children and push old ladies in front of cars |
| 13:30:28 | Araq | sounds like you're misusing 'nimble' for 'niminst' |
| 13:31:05 | enthus1ast | propably |
| 13:31:32 | FromGitter | <jrfondren> https://nim-lang.github.io/Nim/niminst.html |
| 13:32:23 | enthus1ast | but then it's not an git repo |
| 13:32:42 | poopBot | hmm, duckducking a video share site sux, i need somesite that wont blure my video, like some hastbin |
| 13:33:19 | FromGitter | <jrfondren> well you said you found something that works for you. if it doesn't, I think either nimble can be modified in one direction or another to support git submodules, or you can use nimble dependencies instead of submodules. Your deps don't need to be in the nimble repository, you can link them like `requires "https://github.com/walkre-niboshi/nim-ncurses >= 0.1.0"` |

| 19:39:52 | poopBot | how to clear list before refill :) |
| 19:39:56 | poopBot | seq |
| 19:40:54 | narimiran | why does it have to be "clear"? |
| 19:40:58 | rayman22201 | This is probably an Araq or a Krux02 question, is there a way to demangle nim function names from C / asm? I'm working on Godbolt support for Nim... |
| 19:41:27 | poopBot | PokerTable = object |
| 19:41:28 | poopBot | 25 deck52:seq[Card] |
| 19:41:28 | poopBot | |
| 19:41:49 | narimiran | poopBot: do not paste multiple lines here. use some pasting service |
| 19:42:02 | rayman22201 | @leorize, `passC:-g` worked btw |
| 19:42:31 | poopBot | sorry i frogot this no discord cant redit xD, hmm when i create an object like this is deck 52 done as let or var or do i need to manly specify for each? |
| 19:44:48 | narimiran | can you change it? (this is a question that you should ask yourself) yes you can. (this is the answer you need to test by yourself) it is a var. (this is the conclusion that you would come up with) |
| 19:45:14 | rayman22201 | also, philosophical question, should I hide nim runtime functions in Godbolt, or leave them shown? I.E. initStackBottomWith, PreMain, etc... |
| 19:46:10 | narimiran | rayman22201: it's great to hear that somebody is working on godbolt support!! bravo! |

| 19:46:13 | FromGitter | <jrfondren> showing's better. it's a compiler explorer after all. you want to see what's going on. that said, I don't know how it looks with all that. |
| 19:46:56 | rayman22201 | @narimiran :-) It's a project I have been thinking about for a while. I decided to just say screw it and dive in. |
| 19:47:05 | poopBot | 'pt.deck52' cannot be assigned to |
| 19:47:22 | poopBot | i tryed deck52= newSeq(Card) |
| 19:47:30 | rayman22201 | @jrfonden, I'm inclined to agree with you, but I wanted to get some other opinions |
| 19:47:32 | FromGitter | <jrfondren> poopBot, so you probably want a var then |
| 19:48:04 | poopBot | thats why i asked when i make objects is it let or var by default |
| 19:48:07 | * | xace joined #nim |
| 19:48:19 | FromGitter | <jrfondren> there's no default. they mean different things |
| 19:48:56 | poopBot | when i create |
| 19:48:58 | poopBot | type |
| 19:49:05 | narimiran | poopBot: here is my test, it works: http://ix.io/1Jf2 |
| 19:49:07 | poopBot | Person = object |
| 19:50:15 | rayman22201 | I'm very sad because I think I'm going to have to make a new nim syntax highlighting config file for godbolt... Godbolt uses monaco, which is what vscode uses, and yet the syntax format is completely different (┛ಠ_ಠ)┛彡┻━┻ |
| 19:50:22 | poopBot | proc fill_deck(pt:PokerTable)= << hmm i am using it in proc meybe thats why is coplaing |
| 19:50:40 | poopBot | do i need to do proc fill_duck(var pt:PokerTable) ? |
| 19:50:50 | FromGitter | <jrfondren> not as a rule |
| 19:50:56 | FromGitter | <jrfondren> it depends on how you're using the arg |
| 19:51:02 | FromGitter | <jrfondren> but yeah with that name, probably |
| 19:51:37 | poopBot | i wanted to just pass it as reference |
| 19:51:45 | narimiran | poopBot: yes, use `var` there |
| 19:52:04 | FromGitter | <jrfondren> if you just want to pass it as reference, change the type to ref object |
| 19:52:30 | * | Jesin quit (Quit: Leaving) |
| 19:53:01 | narimiran | poopBot: updated example: http://ix.io/1Jf4 |
| 19:53:36 | narimiran | but i feel like all these questions could be answered (faster) if you just experimented and tried stuff on your own |
| 19:53:57 | poopBot | hmm i want to have a Poker Table object that will be a var, but i want to have proc that effects that object so i just need to pass ref of it rihg |
| 19:54:10 | narimiran | poopBot: yes, use `var` there |

| 20:01:50 | poopBot | ty it worked, where can i read about seq functions, i am trying to empty/clear it |
| 20:02:17 | narimiran | poopBot: but why you need to clear it before filling it up again? |
| 20:02:53 | narimiran | look at my example posted above, i didn't clear `x.b` seq before calling `fill` |
| 20:02:54 | poopBot | cuz each round i dont collect old cards for players i just drop them create new deck and remix |
| 20:03:12 | poopBot | or at least that was the plan :) |
| 20:04:07 | poopBot | tough i can probbaly do it other whey do buy just assinging card form deck to player whiout really removing it form deck |
| 20:04:08 | narimiran | you can use `setLen` if you want to start from an empty seq: http://nim-lang.github.io/Nim/system.html#setLen%2Cseq[T][T]%2CNatural |
| 20:04:25 | poopBot | but i thinked its easy operation so nothing to lose |

| 20:41:20 | poopBot | hmm is there any inbuild or modul to shuffle/randomize a seq? |
| 20:41:44 | Zevv | I still miss some pieces of the puzzle - how will this work? appending an item to a doubly linked list, the new item will be owned by the next pointer of the tail, and will overwrite the tail of te list itself. The new item passed to the append() proc needs to be owned, but how do you reference an owned type in an 'unowned' way? |
| 20:43:17 | Zevv | and how does append() indicate to the caller that the object passed is now owned by the list? |

| 22:37:54 | FromGitter | <jrfondren> if you use a code pastebin, like http://ix.io/ or https://gist.github.com/ , it'd be easier for me to copy&paste that and try it locally |
| 22:38:10 | FromGitter | <jrfondren> I don't see the problem there. |
| 22:38:18 | FromGitter | <jrfondren> try running 'nim check' against your file instead. |

| 23:12:22 | FromGitter | <jrfondren> in principle that can't be a single number; it depends on how much of the stack you're consuming on each recursive call. |

| 23:18:44 | FromGitter | <jrfondren> without tail tail optimization, avoid recursion :/ you can write iterative code and work with an explicit stack data structure, instead. |

| 23:24:30 | FromGitter | <jrfondren> rutenl, a proc that just increments a global variable and calls itself until that variable exceeds 100mil can't run to completion on -d:release, so I reckon TCO doesn't happen in general. |
| 23:25:51 | FromGitter | <jrfondren> ... TCO *does* happen for funcs though |
| 23:26:07 | FromGitter | <jrfondren> so you need {.noSideEffect.} for it |
| 23:26:14 | rutenl | hmm yea, this case it's minimax, where the recursion is guaranteed to end, but I don';t know if the compiler can be expected to know that |
| 23:26:31 | rutenl | and it does have a side effect for now as it uses a transposition table (cache) |
| 23:26:49 | FromGitter | <jrfondren> if you use `func` instead of `proc` you'll get TCO. it might work to pass that table around as a parameter |
| 23:27:09 | rutenl | i'll try that |
| 23:27:12 | FromGitter | <jrfondren> in devel you can use {.noSideEffect.}: blocks |
| 23:27:42 | FromGitter | <jrfondren> so in a func body, {.noSideEffect.}: blatantlyModifyGlobalTranspositionTable() |
| 23:28:19 | FromGitter | <jrfondren> unrelatedly, I'd appreciate it if anyone has a better way to do this: https://gist.github.com/jrfondren/e9d60761ce727acabc6256ebd22e6115 |
| 23:30:08 | FromGitter | <jrfondren> it's not just needing 8 variations of the query, it's also needing to give it different arguments depending on the query. |
| 23:34:06 | shashlick | smitop: you can use staticExec |

| 23:41:49 | FromGitter | <jrfondren> for a start a varargs template works well here... |
| 23:46:50 | rutenl | if i have a table Table[(int, int), (int, int)] i should be able to do table[(intA, intB)] = (intC, intD) right? |
| 23:47:12 | rutenl | it's giving me a type mismatch |

| 23:49:23 | rutenl | https://gist.github.com/RuurdBijlsma/e81c2a4be85ba4d441f0e98432169ca6 is the code if anyone would like to help, at line 30 nim gives me a type mismatch I can't figure out |
| 23:58:23 | FromGitter | <jrfondren> @rutenl, add a 'var' before the Table parameter in negaMax() |
| 23:59:29 | FromGitter | <jrfondren> `Error: type mismatch: got <Table[tuple of (int, int), tuple of (int, int)], tuple of (int, int), tuple of (int, int)>` ⏎ `proc `[]=`A, B (t: var Table[A, B]; key: A; val: B)` |
| 23:59:53 | FromGitter | <jrfondren> parameters are immutable, see. |
