00:07:09ldleworkWhat am I supposed to do?
00:07:24ldleworkAre objects immutable?
00:07:36PrestigeIf they are declared with var they are mutable
00:08:08ldleworkthe fields or the object

02:30:19FromDiscord<InventorMatt> I am trying to use the asyncdispatch library and when I use await on the proc I am using I get "Error: Await only available within .async" as an error. the proc I am using has the async pragma attached so does anyone have an idea for a solution?
02:38:56shashlickis the marshal module not able to handle references?
02:39:16shashlick$$ works but to[Type] complains
02:53:17leorize[m]@InventorMatt can we see the code?
02:55:36FromDiscord<InventorMatt> here is the small library I update to work with modern nim https://play.nim-lang.org/#ix=2oN0
02:55:51FromDiscord<InventorMatt> and here is the tests code in which I receive the error https://play.nim-lang.org/#ix=2oN2
03:02:34FromDiscord<Rika> @InventorMatt use waitfor instead
03:02:39FromDiscord<Rika> of await
03:03:03FromDiscord<Rika> await needs to be inside an async proc, if it isnt, use waitfor (will make the proc synchronous)
03:03:26FromDiscord<Rika> not that thats an issue from what i see in the code
03:06:16FromDiscord<InventorMatt> thanks that did solve that problem.

03:08:16FromDiscord<InventorMatt> do you know what define used to do? it was in the old code and it says it has been deprecated but I don't know what I am supposed to replace it with?

03:20:40FromDiscord<Rika> nope
03:20:50FromDiscord<Rika> someone else might now
03:20:52FromDiscord<Rika> (edit) 'now' => 'know'
03:26:09shashlicklooks like marshal doesn't like it if a field points back to the object ref
03:41:52leorize[m]@InventorMatt it's the in-code version of the `-d:` switch
03:42:11FromDiscord<Rika> oh, its deprecated?
03:42:37leorize[m]it's undeprecated on devel btw :P
03:42:42leorize[m]don't worry too much about it

04:14:46FromGitter<Knaque> Say I have an enum with a string value (i.e. `type MyEnum = enum One = "text1", Two = "text2"`). Is it still possible to get the name of the enum?
04:15:34FromGitter<Knaque> To elaborate, `echo One` prints "text1," but I'd like to be able to get both its name and value separately.
04:18:57FromDiscord<Rika> .repr?
04:19:32FromDiscord<Rika> nah, didnt work..
04:19:33*rockcavera quit (Remote host closed the connection)
04:21:12TongirKnaque: This may be what you need https://nim-lang.org/docs/strutils.html#parseEnum%2Cstring
04:22:51Tongirso parseEnum[MyEnum]("text2") should get you MyEnum.Two
04:22:58FromDiscord<Rika> Tongir: theyre looking to print the name of the enum, not get the value
04:23:01FromDiscord<Rika> from a string
04:23:14FromGitter<Knaque> Yeah, that doesn't quite look like what I'm looking for.
04:23:15FromDiscord<Elegant Beef> it's just .ord for the value
04:23:35FromDiscord<Elegant Beef> One.ord gets you the int value and One returns the string value
04:23:36FromDiscord<Rika> they mean the name of the enum entry, not the number value
04:24:14FromDiscord<Rika> so if they echo enumname(One) it should print "One" (enumname is for example, not real)
04:24:22TongirOh
04:24:26TongirHaha
04:24:28FromGitter<Knaque> Rika is right on the money.
04:25:54TongirMacro, perhaps
04:26:57FromGitter<Knaque> As someone with little understanding of metaprogramming, how might I do that?
04:27:29*stefantalpalaru quit (Quit: ZNC 1.7.5 - https://znc.in)
04:27:29FromDiscord<Elegant Beef> Well in this case the macro basically just returns the identifier
04:27:50*stefantalpalaru joined #nim
04:27:57FromDiscord<Elegant Beef> It's a weird thing to want the actual enum name
04:28:02FromDiscord<Elegant Beef> May i ask why you want that?
04:28:08FromDiscord<Rika> it wouldnt be able to do things like enumname(1.MyEnum) or enumname(parseEnum[MyEnum]("text1"))
04:28:10TongirYeah. The One is already an ordinal value of 0 (I think it starts at 0), but the field should be available in the AST
04:28:40TongirI'll have a fiddle Knaque
04:28:55FromGitter<Knaque> Thanks Tongir.
04:29:50FromGitter<Knaque> As for why I need this, Elegant Beef, I don't really have a good answer to offer. I just think it's something I'll need for this project.
04:36:31TongirKnaque: https://play.nim-lang.org/#ix=2oNe
04:36:37TongirMaybe that does what you want

06:29:41FromDiscord<Elegant Beef> Man i cant read

06:30:30FromDiscord<Zed> ok that works
06:31:01PMunchAnd if you want qualified imports: https://play.nim-lang.org/#ix=2oNy

06:31:48FromDiscord<Elegant Beef> qualified imports == poo
06:32:00FromDiscord<Zed> why
06:32:02FromDiscord<Zed> ?
06:32:32FromDiscord<Elegant Beef> Well cause it interferes with the UFCS
06:32:43FromDiscord<Elegant Beef> but if you are using parameterless procs then it's no different
06:33:01FromDiscord<Zed> sometimes you dont want to import everything from a library

06:35:17FromDiscord<Elegant Beef> Qualified imports are always weird to me coming from C#
06:35:30FromDiscord<willyboar> i personally never have a problem with
06:35:31FromDiscord<Elegant Beef> We have name spaces to divide code
06:35:38FromDiscord<Elegant Beef> In nim we have modules to do so
06:36:32FromDiscord<Elegant Beef> I could be wrong but if you're often including/excluding specific procs you could always make a module that exports the procs you want
06:37:50FromDiscord<Zed> do you mean we dont have namespaces?
06:37:57FromDiscord<Elegant Beef> No i meant in C#

06:44:18FromDiscord<willyboar> (edit) 'too' => 'to'
06:45:40FromDiscord<JSGrant> I tried to switch to NixOS like a dozen times over the past few-years, and there are many parts I really like -- but there's no way I see it winning long-term over Silverblue; The all-or-nothing nature of it is just brutal unless you are willing to invest 100%
06:47:29FromDiscord<JSGrant> Like I REALLY WISH Silverblue had some kind of declarative-config file; Home-manager is awesome, etc ... but really having that ability to "be mutable when convenient" for mass adoption.

09:08:32FromDiscord<mratsim> It sounds like ECMAS(cript)
09:08:37FromDiscord<mratsim> but I'm sure it's not that
09:08:39Zevvhaha, not quite :)
09:08:41FromDiscord<mratsim> so what is it?
09:09:59Zevvgeneric genetic algorithm. You ask it for a N-size vector of things, you do your test/simulation, pass back the error of your end result, and repeat until err is small enough
09:10:06Zevvhttps://en.wikipedia.org/wiki/CMA-ES
09:10:41Zevvit's usable for tons of funny stuff. There's often better algorithms fiting specific domains ,but this one seems to be the most optimal solution if you don't know what you're doing
09:10:45Zevvwhich is often the case with me

10:21:54FromDiscord<Shucks> Don't you just helped me to do that WriteProcessMemory stuff?
10:27:07PMunchYes?
10:29:22PMunchNice, now I've got a small Nim script that asks i3 for open windows, tries to guess the icon name based on the class, then shows all the programs with icons in a searchable list, and switches to the chosen one
10:32:23alehander92why do you need to write process memory

10:45:28FromDiscord<él liquido> yea, why?
10:45:41FromDiscord<Recruit_main707> i dont know how to use it :P
10:46:00FromDiscord<Recruit_main707> do you have an example i can see?
10:46:32FromDiscord<él liquido> so first you need to open a file with `open()`, and then map an area of the file to memory using `mapMem`
10:47:05FromDiscord<Recruit_main707> right, and then how do i edit, lets say the first two characters
10:47:18FromDiscord<él liquido> write to `yourFile.mem`
10:47:47FromDiscord<él liquido> so you basically `cast[ptr UncheckedArray[uint8]](yourFile.mem)` and write to that
10:48:40FromDiscord<Recruit_main707> character by character?
10:49:15FromDiscord<él liquido> yes
10:49:37FromDiscord<él liquido> if you cast it to a `ptr UncheckedArray[T]` it basically acts as an array of `T`
10:49:57krux02alehander92: if something is supported by all current major platforms, you can call it universal. If this property changes and a platform does not have files for examples (old consoles like NES and SNES don't have it for example), then it can't be called universal anymore and you are in a messed up situation. But I wouldn't try to spend any brain cell in the design the os module with thinking of hypothetical future os develo
10:49:57krux02some point you just have to redo it.
10:50:15alehander92yeah i guess so
10:50:39FromDiscord<Recruit_main707> i wish we had a higher level function to use memfiles
10:50:40alehander92it's the old stdlib vs others discussion

10:51:38FromDiscord<él liquido> @Recruit_main707 but it doesn't play well with memfiles, then. they're an inherently low-level feature
10:51:39krux02in snes and nes, the ROM is directly addressable memory.
10:52:13krux02putting the module into the console is literally loading the game, physically.
10:52:31krux02Therefore you also don't have any loading times.
10:52:43alehander92sounds reasonable
11:02:43krux02It is also perfect privacy and process isolation, because every program/game comes pysically attached with its own writable memory. There is no persistent memory on the console. In other words, programs cannot read the memory of other files.
11:06:27alehander92<3
11:06:33alehander92cool
11:06:57alehander92i wondered if a more fine-grained permission model would come to any os soon
11:07:34alehander92something like "this process can access this pattern of files, this memory and use max this ram" etc
11:08:15alehander92maybe fuschia handles can model some of it and i am sure research os-es have much more sophisticated stuff
11:08:26alehander92but e.g. i want it for linux
11:13:38PrestigeIs there a way to package an external executable inside of a Nim program?
11:14:08PrestigeI'm wanting to write something that uses fzf (a program written in go) but don't want the user to have to install an external dep
11:14:34*bacterio quit (Ping timeout: 240 seconds)
11:15:15alehander92does the license permit it!!
11:15:56PrestigeMit
11:16:01alehander92if it depends on the go runtime and everything it might be easier to make him install it
11:16:14FromDiscord<él liquido> Prestige: with
11:16:36FromDiscord<Rika> Install it via the package manager
11:16:40FromDiscord<Rika> As a dep I mean
11:17:46PrestigeIt's for my work, we're doing a hackathon. People using only macs, don't have a package manager
11:18:14*dddddd joined #nim
11:18:28alehander92eh cant you just ship a static binary
11:18:35alehander92doesnt go produce stuff like that
11:18:52PrestigeYeah, just not sure if/how I could wrap it with Nim
11:19:12PrestigeAnd I'm trying to avoid it being 2 separate binaries
11:20:40alehander92well you can just .. invoke it
11:20:50bungstatic read it as file extract it to somewhere then run it ?
11:21:05alehander92does the hackathon
11:21:30alehander92have rules for how many files
11:21:33alehander92you produce?
11:22:43alehander92not sure how packaging typically works on osx tho
11:22:44PrestigeNope I just wanted it to be an easy install for people but I suppose I could have an installer install the fzf executable as well
11:22:50PrestigeYeah me either lol
11:23:16alehander92cant you make a brew package
11:23:20alehander92or is that not common now
11:25:21PrestigeIt is, but it's going to be an internal (to the company) program
11:26:17PrestigeWas hoping to have a single executable but if that isn't going to work I'll just do something else
11:29:29alehander92eh two binaries still seem good to me
11:29:35alehander92after all `fzf` is useful
11:29:43alehander92so they just get two tols
11:29:47alehander92tools maybe b
11:30:02alehander92but yeah it can be frustrating

11:48:43PMunchYou can use staticRead/slurp to grab the program file, and then on runtime just write it out to a file again..

11:51:14FromDiscord<Technisha Circuit> How do i use `loadLib` from dynlib to:↵A) Get a function↵B) Get a variable
11:51:40FromDiscord<Technisha Circuit> I'm trying to make a command handler for dimscord with .so files so i can load them dynamically
11:51:59PMunchLike this? https://nim-lang.org/docs/dynlib.html
11:52:23PMunchThat is by using `symAddr` to get the symbol
11:52:38krux02PMunch: no that is not how you are supposed to write a quine
11:52:52PMunchkrux02, quine?
11:53:07krux02a quine is a program that prints out its own source code.
11:54:05PMunchAh, never heard that term before
11:54:28PMunchBut this wasn't printing out its own source, this is just "unpacking" a part of the program as it execute

13:18:36FromGitter<kaushalmodi> it was on my wishlist to have something like this in Nim: https://github.com/p-gen/smenu/blob/master/README.rst

13:20:01FromGitter<kaushalmodi> also, not as a standalone binary but a library
13:20:01FromGitter<kaushalmodi> something that work like `pickOne(@["opt1", "opt2", ..])`
13:20:16shashlickIt's only tested on windows but that's cause fzf works well on Linux
13:20:21FromGitter<kaushalmodi> .. and the `pickOne` then launches that fzf/smenu like interactive selector in the terminal
13:20:38shashlickThe code gives you an idea what it can do
13:20:43shashlickShould work in Linux
13:21:03FromGitter<kaushalmodi> I'll have a look. Thanks
13:23:04shashlickThe thing with fzf is that it cannot return info back to the caller
13:23:35shashlickCause if you want to read back the output, you don't see anything
13:23:35FromGitter<kaushalmodi> hmm, I might venture into a wrapper for smenu
13:23:48FromGitter<kaushalmodi> unfortunately it doesn't have a good API
13:24:03FromGitter<kaushalmodi> so I'll need to use the same startProcess approach
13:25:44shashlickYou could write the selection to a file and then read it back perhaps
13:28:16FromGitter<kaushalmodi> yes, I'll need to do that.. or probably smenu would return the selection as TaintedString returned by startProcess

14:19:08FromDiscord<Shucks> So `json` has `parseFile` but not `toFile`?
14:19:34Yardanicomake a PR
14:19:36Yardanicoif you want
14:29:33FromGitter<Vindaar> @Shucks: well `toFile` is just `writeFile("someFilename", $someJson)`
14:30:08FromDiscord<Shucks> yea doing that atm. ``` let config = %*s↵ write_file("config.json", $config)```
14:30:50FromDiscord<Shucks> just wondering if I could just save up that config variable. `$%*s` doesnt seems to work
14:31:54FromGitter<Vindaar> I'm confused, what's `s` exactly? `%*` is the macro which takes "literal" json, no?
14:32:17Yardanico@Shucks easily
14:32:34YardanicowriteFile("config.json", $(%*{"a": "b"}))
14:32:39Yardaniconot sure if you'd want that though
14:32:54FromDiscord<Shucks> > I'm confused, what's `s` exactly? `%*` is the macro which takes "literal" json, no?↵@Vindaar[Gitter]#0000 Yea. `Convert an expression to a JsonNode directly,`
14:33:01Yardaniconah
14:33:04FromDiscord<Shucks> That looks good. Thanks @Yardanico
14:33:12FromGitter<Vindaar> yes, so in your code `s` isn't actually `s` but you meant it as a placeholder?
14:33:40FromGitter<Vindaar> but yes, @Yardanico's approach works
14:33:41Yardanico@Vindaar %* works with variables too
14:34:03FromGitter<Vindaar> well, yes but only converts a type to a JsonNode in that case
14:34:04FromDiscord<Shucks> `"config.json".write_file($(%*s))` That compiles 🙂 thanks
14:34:21FromGitter<Vindaar> so you might as well just write `% s`
14:34:35Yardanicoah right
14:37:33FromDiscord<Shucks> `%` takes a JsonNode no? `s` is a object. Sorry for not clearing that
14:37:39Yardanicono
14:37:45Yardanico% is for converting different values to JsonNode
14:37:57Yardanicoit's defined for most standard types including generic "object" and "tuple"
14:38:21Yardanico%* is a macro that recursively adds % to all values in the expression
14:40:20FromDiscord<Shucks> Alright, works aswell. Thanks

14:48:28PMunchHaha, I've started using it to try it out :P
14:48:43FromDiscord<Shucks> Yea im still confused about the style behaviour. Like im coming from python, theres pep8 which tells you what indentation etc. you should use. And nimpretty itself doesn't seems to do much to be honest.
14:49:00FromDiscord<Shucks> Nah I need to remove that dots lol. I wasnt sarcastic ;D

14:49:42Yardanicofor some info you can check https://nim-lang.org/docs/nep1.html

17:32:30PrestigeI'm using the regex match function and passing in a sequence I've initialized - it looks like it doesn't fill the sequence though, I'm having to initialize it with some size.. Is there a way to do this more dynamically?
17:43:20leorize[m]wdym?
17:45:06PrestigeSince the proc has an array as an out parameter I'm having to initialize my sequence with some size, or else I don't get any matches back
17:45:30PrestigeIf I initialize it as an empty seq I won't get any matches
17:46:39leorize[m]that's a weird design then
17:46:40leorize[m]are you using nim-regex or the stdlib ones?
17:47:59FromDiscord<treeform> Hey guys do you know if there is a way to check if file exists in a `static:` block? Important OS does not work. Using exceptions does not work as well...
17:48:01PrestigeStdlib - yeah I expected to either have an iterator or a seq returned
17:48:30disruptektreeform: there's, like, fileExists and existsFile and iirc one of them works statically.
17:49:17FromDiscord<treeform> I tried it. I'll try it again.
17:50:10FromDiscord<Recruit_main707> should memory mapped files be faster than sockets?
17:50:19FromDiscord<treeform> hmm both of them say `Error: this proc is not available on the NimScript target; usage of 'existsFile' is an {.error.}`
17:50:20disruptekyeah.
17:50:28disruptekweird.
17:50:45FromDiscord<Recruit_main707> disruptek, is that yeah to me?

19:44:37disruptekwhat?
19:44:59disruptekit's the one from kostya's benchmark game.
19:45:26disruptekit appears to have gotten about 10% slower in refc, too.
19:47:17Zevv50% spent in nimPrepareStrMutationV2
19:48:09ZevvI've been there
19:48:16disruptekhonduras?
19:48:18FromDiscord<Varriount> Zevv: Here's an idea - turn a [jq](https://stedolan.github.io/jq/) program into Nim code at compile-time. 😄
19:49:21Zevvvarriout: Great idea, when will you get started? :)
19:49:36Zevvdisruptek: nope, not yet
19:49:59Zevvanway, that proc is basically an alloc and a memcpy
19:51:27Zevvbut only for string literals. otherwise its a noop
19:52:34Zevvwhich actually does not make sense
19:52:41disruptekfun.
19:52:47FromDiscord<dom96> oh cool, Nim is on HN front page
19:54:52*NimBot joined #nim
19:56:05Zevvdisruptek: I think we can optimize something here
19:56:18Zevvit calls that proc approximately 2500000000 times
19:56:19disruptekcool.
19:56:22disrupteklol
19:56:27Zevveven though it never gets passed a strlit
19:56:38disruptekit has been slow for ages.
19:59:56Zevvbwah unreadable code with templates and whenNimVms
20:01:17Zevvwell, with every 'result[outputIndex] = alphabet[x and 63]' the compiler also emits a call to nimPrepareStrMutationV2()
20:01:44Zevvso it's a function call for every processed char it seems
20:03:02Zevvnot something you want in your inner loop, typically
20:06:52*silvernode quit (Ping timeout: 246 seconds)
20:17:18PrestigeSo in bash when I prompt for input I can set a default value that the user can edit (as if they had typed it themselves), trying to replicate that with Nim. Is there a way to output text to the terminal in that manner?
20:19:31krux02`Prestige: not that I know about. Terminal is rather bare bone in that respect.
20:20:13krux02`what you need is a line editing function.
20:23:12krux02`something like gnu readline.
20:23:29FromDiscord<Rika> dont we have linenoise
20:23:46FromDiscord<Rika> the line noise wrapper thing or something
20:24:07krux02`linenoise is not really good.
20:24:12krux02`I tried it out.
20:24:44krux02`To my experience is is much better if you do not use line noise at all, and then start your problem with rlwrap myprogram arg1 arg2 ...
20:24:44Araqa good optimizer could hoist nimPrepareStrMutationV2 out of the loop
20:24:47*Araq sighs
20:25:31Zevvit doesn't :(
20:25:50Zevvit's not in the same module. Maybe flto will notice
20:27:04Zevvbut it now gets called for any assignment of a s[]
20:28:27Araqah ok
20:28:33Zevvflto does speed up a factor of 2
20:28:35Araqwe can split it in a hot and cold path
20:28:49Araqto help the C optimizer out
20:29:30Zevvyeah but the implementation of nimPrepareStrMutationV2 does not live in the same c file, so it can't do much there
20:30:50Zevvnice of flto to look a bit further, but not something we want to rely on I guess
20:35:09PrestigeHm yeah krux02` I may look into it anyway, I need that functionality for what I'm doing
20:38:37Zevvstill, even with the call optimized out, for these kind of tight loops it is considerable overhead to check for string literals on every single assignment.
20:40:13disruptekZevv: don't be a baby.
20:40:19disruptekit's not your cpu to burn.
20:40:26disruptekwinter is coming.
20:41:11Zevvoh I never cared for that. 100% of the energy spent in my computers is put to good use in winter

22:11:24disruptekdon't worry about it.
22:11:35disruptekyes, it has some amount of dead code elimination.

22:55:10FromDiscord<Rika> what do you mean
22:55:36FromDiscord<Rika> you can make arguments variable, `proc something(arg1: var string) = arg1 = "changed it"`
22:55:53FromDiscord<Rika> @Spy653 see above

22:57:12FromDiscord<Spy653> could you expand on that example for me
22:58:05FromDiscord<Rika> `proc something() = ` is a function declaration↵`arg1: string` means there is an argument that takes in a string↵`var` here makes it so you can mutate it in the function
22:59:59FromDiscord<Spy653> I'm not understanding the `= arg1 = "changed it"`
23:00:02FromDiscord<Spy653> oooh wait
23:00:10FromDiscord<Rika> thats the body
23:00:18FromDiscord<Rika> in indented style itll look like this
23:00:30FromDiscord<Rika> ```proc something(arg1: var string) = ↵ arg1 = "changed it"```
