00:47:16FromDiscord<iWonderAboutTuatara> pretty sure $ can cast a char to a str
00:47:30FromDiscord<iWonderAboutTuatara> oh wait nevermind, I misread
01:04:22PrestigeWhat's the point of initDoublyLinkedList when you can just use DoublyLinkedList[T]()? The proc is empty
01:04:28Prestigehttps://github.com/nim-lang/Nim/blob/version-1-2/lib/pure/collections/lists.nim#L145
01:04:38disruptekit might have a role in the future.
01:04:45Prestigeah good point
01:07:56PrestigeReason I'm asking is because of this example: https://play.nim-lang.org/#ix=2zEv
01:08:28PrestigeI was attempting to create the list as a var and assign result.bar = ref myList, but it is incorrect
01:10:12PrestigeSomething like this: https://play.nim-lang.org/#ix=2zEx not sure what I'm missing

01:46:38FromDiscord<exelotl> when I make a set[range[0..2047]], it produces an array of 256 u8 under the hood
01:46:59FromDiscord<exelotl> is there a way to make it produce an array of 128 u16s instead ?
01:50:18FromDiscord<exelotl> I tried applying {.size:2.} to the set itself, this results in the set becoming a single u16 which is no good x)
01:56:11FromDiscord<Rika> I do not think so, and I do not see the benefit to doing so
02:05:08*lritter joined #nim
02:06:15FromDiscord<exelotl> admittedly I haven't looked at the asm so it might make no difference, but basically I'm working with a region of memory that prefers 16-bit access (8 bit access is no faster or slower, but I guess more likely to require extra shifts/masking)
02:08:00FromDiscord<exelotl> Probably the more important one would be when working with memory that prefers 32 bit access. Since the GBA has a 32 bit CPU, if I could have a set backed by an array of u32s, that would be way preferable because the values wouldn't require any shifting/masking at all.

03:18:42FromDiscord<shashlick> does travis-ci allow testing on alpine? without docker?
03:24:39FromDiscord<Avatarfighter> Whats the best way of turning a seq of bytes to a string?
03:25:41FromDiscord<Elegant Beef> Should be able to cast to string
03:26:16FromDiscord<Avatarfighter> ok that's what I thought lmao
03:26:38FromDiscord<Avatarfighter> i definitely didn't iterate through the string and do `result = result & chr(b)`
03:26:54FromDiscord<Avatarfighter> through the seq of bytes I mean
03:28:36FromDiscord<Avatarfighter> goddamn sometimes i write the ugliest looking code
03:31:16FromDiscord<shashlick> why not just cast to cstring and use $
03:32:53FromDiscord<Avatarfighter> well one reason is because I didn't think of that
03:33:44FromDiscord<Elegant Beef> !eval let a = @['h'.byte,'e'.byte, 'l'.byte, 'l'.byte, 'o'.byte]; echo cast[string](a)
03:33:48NimBothello
03:34:03FromDiscord<Avatarfighter> well uhm
03:34:14FromDiscord<Avatarfighter> i guess i can push my homemade crypto to github now 🙂
03:34:22FromDiscord<PizzaFox> isnt the `.byte` for the 1-4th items unnecessary @Elegant Beef
03:34:32FromDiscord<Elegant Beef> Nope no implict conversion from char to byte
03:34:40FromDiscord<PizzaFox> sad
03:34:52FromDiscord<Elegant Beef> I mean it takes 2 seconds to implement but i didnt want to

03:36:39FromDiscord<PizzaFox> its nicer than figuring out the nim regex implementations lol
03:36:55FromDiscord<Elegant Beef> Nim's regex is just PCRE
03:36:55FromDiscord<PizzaFox> although my peg code doesnt work and the regex code kinda worked so
03:37:05FromDiscord<PizzaFox> yeah but nre vs re
03:37:24FromDiscord<PizzaFox> if i were a nim developer i would simply create a single regex lib
03:37:25FromDiscord<Elegant Beef> I briefly looked at npeg, and went "yep i understand some things"

03:38:45FromDiscord<PizzaFox> listen dude
03:38:51FromDiscord<PizzaFox> i just want to make my peg snippet work
03:39:53leorizeso you wanna match everything but whitespace?
03:40:07leorizeactually I'm not that well versed in regex lol
03:40:23FromDiscord<PizzaFox> `\w` in both nim builtin PEGs and regex is `[0-9A-Z_a-z]`
03:40:33leorizeis this dash (-) or whitespace?
03:40:34FromDiscord<PizzaFox> i want to match that + the hypen `-`
03:40:38leorizeah ok
03:40:51FromDiscord<PizzaFox> peg is mad because i cant put a `\w` in the `[]`
03:41:17FromDiscord<PizzaFox> surely there is a solution
03:41:34leorizejust use an ordered choice?
03:41:41FromDiscord<PizzaFox> wat
03:41:49leorizeso `'-' / \w`?
03:41:58FromDiscord<PizzaFox> > Apply expressions A, ..., Z, in this order, to the text ahead, until one of them succeeds and possibly consumes some text.
03:42:08FromDiscord<PizzaFox> this would work i think??
03:42:39FromDiscord<PizzaFox> ```nim↵peg"(\w / \-)"↵[\-0-9A-Z_a-z] == type Peg↵```
03:42:49FromDiscord<PizzaFox> seems legit
03:43:33FromDiscord<PizzaFox> it is in fact legit

03:46:58FromDiscord<Elegant Beef> I mean if you're using a cryptography library, i'd wager you'd want to audit it 😄

03:47:17FromDiscord<Elegant Beef> MIT removes liabaility

03:51:43FromDiscord<Avatarfighter> do i do the copyright of the js library or the library the js library was based off of?

03:52:10FromDiscord<Avatarfighter> ok
03:52:10FromDiscord<Avatarfighter> hm
03:52:28FromDiscord<Avatarfighter> well i kind of started with the js library and then you helped me fix the c library i continuedd with

07:41:57FromDiscord<iWonderAboutTuatara> it was a one off bug, never had an issue with this before

07:46:10FromDiscord<iWonderAboutTuatara> I prefer tabs
07:46:28FromDiscord<iWonderAboutTuatara> I've always used tabs
07:48:49FromDiscord<Elegant Beef> I also prefer tabs, but to support lack of unanimous editor support for customizing the size of tabs we get spaces 😄
07:49:21FromDiscord<Elegant Beef> you *can* use source code filters to replace tabs with spaces though

12:02:35FromDiscord<Recruit_main707> i dont get Araq's latest rfc, whats the difference between `cast(noSideEffect)` and `noSideEffect`?
12:03:45Yardaniconewer syntax is easier to search for in files
12:03:47Yardanicoand easier to understand
12:04:04Yardanicoyou see, right now {.noSideEffect.} can be used both as an annotation for the proc and as an annotation for a code block
12:04:38Yardanicoand if in the first case it means "proc has no side effects", in the second one it means "compiler, I say to you that this code block has NO side effects, and you must obey!"
12:04:49supakeenPoor compiler.
12:05:01Yardanicoso there are two exactly opposite meanings depending on the location of the pragma
12:05:08Yardanicosame goes for others like gcsafe
12:05:16FromDiscord<Recruit_main707> i see
12:05:21FromDiscord<Recruit_main707> makes sense now

12:09:18Yardanicobasically you just make an array of proc pointers in Nim
12:10:07FromDiscord<Recruit_main707> this could be worth it when we get default values
12:15:40supakeenMrm, is there a way to make a type generic?

12:15:59supakeenPerfect.
12:16:20Yardanicoyou don't even have to use T in your object fields, but then you'll have to specify T explicitly any time you instantiate the type
12:17:31supakeenNo this is perfect, I'm implementing a bunch of LCGs and some are uint64 others are int32, etc.
12:22:36supakeenhttps://github.com/supakeen/simba/blob/master/src/simba/lcg.nim seems to work fine :)
12:24:31FromDiscord<Recruit_main707> do you need to add all the 'u32 even when specifying the type before?
12:25:22FromDiscord<Recruit_main707> yep, apparently you need to
12:51:31Yardanicowhere exactly?
13:00:23FromDiscord<flywind> ```nim↵const useWinVersion = defined(Windows) or defined(nimdoc)↵```
13:00:33Yardanicodefined(windows) :)
13:00:44FromDiscord<flywind> This line makes it hard to build docs in `linux`.
13:00:46*natrys quit (Quit: natrys)
13:00:50Yardanicodoes it?
13:01:20Yardanicoit's here because docs should look the same for linux and windows and other platforms
13:01:22FromDiscord<Rika> i dont see why the nimdoc portion should be there
13:01:29Yardanicobecause docs are the same anyway
13:01:36Yardanicoso you don't have to replicate docs for each proc for different OS
13:01:39FromDiscord<flywind> For external library, it exports windows version SocketHandle
13:01:49Yardanicoso usually the windows proc has documentation, and for linux or others it doesn't
13:02:23FromDiscord<flywind> sent a code paste, see https://paste.rs/V9J
13:02:23FromDiscord<flywind> So I got
13:03:09FromDiscord<flywind> wrong msg
13:03:16FromDiscord<flywind> sent a code paste, see https://play.nim-lang.org/#ix=2zH3
13:03:38Yardanicowell, this means that you import both winlean and posix
13:03:45Yardanicoand need to specify explicitly
13:03:59FromDiscord<flywind> This is causes by `defined(nimdoc)` in stdlib.
13:04:05Yardanicobut it's for documentation
13:04:36FromDiscord<flywind> Yea, users may want to build docs in linux
13:04:43FromDiscord<flywind> Yea, I mean docs
13:05:25FromDiscord<flywind> stdlib use `export SocketHandle` to export wrong SocketHandle in nimdoc
13:05:39Yardanicoyes, and your module should be cross-platform :P
13:05:40Yardanicohttps://github.com/nim-lang/Nim/issues/8989
13:05:42disbot➥ `defined(nimdoc)` special case causes `nim doc` failures, eg with jester: Error: undeclared identifier: 'EWOULDBLOCK' ; snippet at 12https://play.nim-lang.org/#ix=2zH4
13:08:00FromDiscord<flywind> I can avoid this by hand, namely `import nativesockets except SocketHandle`. Are there better ways?
13:11:32FromDiscord<flywind> Or `runnableExamples` should not be advised to use with `stdlib`.
13:12:31Yardanicowell, if you have runnableExamples, the code should then run on any platform you want to build docs on
13:27:28FromDiscord<flywind> Ok, I find a work around. The docs servers should download docs files from latest release zip files in github.

16:10:42FromDiscord<shashlick> Yes
16:11:12FromDiscord<shashlick> I'd use nimgrep but 1.0.x doesn't support the --follow flag
16:11:45FromDiscord<shashlick> Busybox find doesn't support egrep regex
16:12:09disruptekisn't this like 10 lines of nim?
16:12:26FromDiscord<shashlick> I have to search at compile time so using walkDir + nim-regex is too slow

16:46:20FromDiscord<whisperdev> @Vindaar https://play.nim-lang.org/#ix=2zIc
16:46:51FromDiscord<whisperdev> I think it's because of the additional call to EnumServiceStatus. I guess the "Get-Service" commandlet is much smarter and needs just a single call
16:48:11FromDiscord<haxscramper> Bad wording. I want to get rid of error, not expand macro. `expandMacros` is just one possible workaround, but I'm interested if there is anything for actually fixing the issue itself. `macro expand*(body: typed): untyped = body` works too, but then I need to write `expand case ():`

17:24:09FromDiscord<Avatarfighter> that is super cool though
17:24:44FromDiscord<Zachary Carter> the coolest part is the vertices and indices for the mesh are all calculated on the GPU

17:25:57FromDiscord<Zachary Carter> the RTS game I've been promising 4raq for years now
17:26:00FromDiscord<Avatarfighter> ahah
17:26:07FromDiscord<Avatarfighter> What is the idea behind your game?
17:29:03FromDiscord<Zachary Carter> I don't really have much yet - my goal is to create a sandbox where I can play around with different ideas easily
17:29:15FromDiscord<Zachary Carter> but at the moment I know it's going to be a RTS and it's going to be science fiction themed
17:29:41FromDiscord<Avatarfighter> I'm excited for you this seems like it would be a lot of fun to play around with and make
17:30:14FromDiscord<Zachary Carter> I think the map editor is going to be the most enjoyable part haha
17:34:07FromDiscord<Zachary Carter> the cool thing is now I can deform the terrain at runtime if I want - so making craters etc from explosions should be possible
17:34:27FromDiscord<Avatarfighter> you don't even know how cool this is to me
17:34:43FromDiscord<Avatarfighter> im really excited for you
17:35:01FromDiscord<Zachary Carter> well it will be cooler when it's not just a stupid example and is actually playable - but that's a ways off
17:35:21FromDiscord<Zachary Carter> I was almost at this point last year - but couldn't quite get the terrain painting working
17:35:58FromDiscord<Zachary Carter> now that I have that I've kind of unblocked myself from progressing further than I was last year - so next up is to getting some animated units moving around the map
17:36:12*supakeen suggests: a tank
17:36:55FromDiscord<Zachary Carter> not a bad idea
17:37:01FromDiscord<Avatarfighter> a plane could be fun
17:37:22FromDiscord<Avatarfighter> mattering on if you have a fog of war feature for your RTS you could have little planes flying around lol

18:02:13FromDiscord<vmcrash> I'm new to Nim. It looks very promising, but the most thing which restrains me from becoming productive is a good IDE with code completion, debugger and refactoring. Did I miss an essential tool? After >17 years of experience with IntelliJ IDEA I don't want to go back into stone age of development without (graphic) debugger or refactoring.
18:02:14FromDiscord<iWonderAboutTuatara> is there a way to import the entire stdlib?

18:19:58FromGitter<deech> Is there a way of overriding C++ methods using multimethods with the cpp backend? They seem pretty close in concept.
18:20:03FromDiscord<haxscramper> To compile some code only on after some nim version I should do `NimMajor > 1 and NimMinor > 2 and NimMinor > 6` or there is a more elegant way for this chec?
18:20:29disruptek(NimMajor, NimMinor) > (1, 2)
18:20:49FromDiscord<haxscramper> deech: no, there isn't any. TO override C++ method you need to create derived class, which nim doesn't do for C++ backend AFAIK

18:24:41FromDiscord<Rika> you're iterating LHS, so 2 elements
18:24:45FromDiscord<Rika> RHS (a) only has 1
18:24:50FromDiscord<haxscramper> `a` is `(Ident "s")`
18:24:55FromDiscord<Rika> aka what does a[1] mean?
18:26:10FromDiscord<haxscramper> you ned `nnkBracketExpr.newTree(a, newLit(i))` to get element at index from `a`
18:26:47FromDiscord<iWonderAboutTuatara> wait if a is an ident

18:27:05FromDiscord<iWonderAboutTuatara> how do I make it pick a seq
18:29:04FromDiscord<Zachary Carter> The reason IntelliJ has all these nice tools is because of the JVM - not IntelliJ

18:30:34FromDiscord<haxscramper> > how do I make it pick a seq↵@iWonderAboutTuatara There is no "sequence" in macro - e.g. when `s` is passed it is just `(Ident "s")` that is /assumed/ to be related to sequence.
18:30:53FromDiscord<iWonderAboutTuatara> how do I work with it as a seq?
18:30:57FromDiscord<haxscramper> The best you can do is `s: seq`, but you will still get `NimNode`.
18:31:10FromDiscord<iWonderAboutTuatara> how would I get the items as an seq?
18:31:14FromDiscord<haxscramper> Generate code like `s[0]`, `s[1]` etc.

18:33:19FromDiscord<Recruit_main707> someone reminds me the difference between idents and syms?

18:34:09FromDiscord<iWonderAboutTuatara> wait how would I go about generating code like that?
18:34:24FromDiscord<iWonderAboutTuatara> I'd need the input to be the induvidual values and not the seq?

18:36:35*Vladar quit (Quit: Leaving)
18:36:41FromDiscord<iWonderAboutTuatara> n & e are declared variables
18:36:46FromDiscord<iWonderAboutTuatara> s is a seq
18:37:00FromDiscord<Recruit_main707> and what gets assigned to what?
18:37:14FromDiscord<iWonderAboutTuatara> n = s[0], e = s[1], etc
18:37:21FromDiscord<Recruit_main707> i see
18:38:24FromDiscord<haxscramper> https://play.nim-lang.org/#ix=2zJs
18:38:28FromDiscord<haxscramper> @iWonderAboutTuatara ^
18:39:11FromDiscord<haxscramper> When in doubt always do `dumpTree` on code you /want to generate/ and then write macro that transforms input into this
18:39:53FromDiscord<iWonderAboutTuatara> I did that, but I'm still confused on getting values from the seq
18:40:24FromDiscord<Recruit_main707> you dont really, you create code that accesses the desired indexes
18:40:26FromDiscord<Zachary Carter> sschwarzer: it's fine to ask, but again there's a reason why the only runtime with the refactoring tools that the JVM has, is the JVM
18:40:34FromDiscord<Zachary Carter> and I guess the CLR is catching up via resharper
18:40:47FromDiscord<Avatarfighter> i love jetbrains
18:40:51FromDiscord<Zachary Carter> if you don't want to debug C/C++ - maybe Nim isn't the right language for you
18:40:56FromDiscord<Vindaar> @iWonderAboutTuatara sorry was afk
18:41:06FromDiscord<Vindaar> this is what you want I assume: https://play.nim-lang.org/#ix=2zJt
18:41:24FromDiscord<Vindaar> doesn't perform any safety checks though 😛
18:41:26FromDiscord<Recruit_main707> they already gave him an example
18:41:28FromDiscord<Rika> @Zachary Carter rather if you're not willing to accept that the ecosystem is still pretty young to have good tools or so
18:41:44FromDiscord<haxscramper> `` s/ s[`i`]/`s`[`i`] ``
18:41:45FromDiscord<iWonderAboutTuatara> oh you can do it with quote do?
18:41:46FromDiscord<Zachary Carter> we basically have what C/C++ devs have at their disposal
18:42:00disruptekjvm is a fundamentally different technology that affords different guarantees.
18:42:06FromDiscord<Zachary Carter> exactly
18:42:09FromDiscord<Vindaar> also regarding importing stuff: especially for competitive programming you wouldn't want to import the whole stdlib, that'd just slow down compilation
18:42:10FromDiscord<iWonderAboutTuatara> `quote do: s['i']`
18:42:12FromDiscord<iWonderAboutTuatara> except w/ backticks
18:42:14FromDiscord<Zachary Carter> we're dealing with C/C++ not Java
18:42:30FromDiscord<iWonderAboutTuatara> We do it in cpp, compile time is not a big worry
18:42:37FromDiscord<Vindaar> just define a helper module which imports the stdlib modules you might need and include that in your files
18:42:38sschwarzerZachary: true, but because the situation is better for the JVM doesn't mean that it's unthinkable that Nim could have better tooling in future. :-)
18:42:54FromDiscord<Rika> keywords are "in the future"
18:42:56FromDiscord<iWonderAboutTuatara> I have a base file where I'm doing that
18:42:59FromDiscord<Zachary Carter> it's not unthinkable no - but my if C/C++ don't have them after n number of years of these languages existing
18:43:12FromDiscord<iWonderAboutTuatara> Oh it's not anything you'd use for normal code
18:43:13FromDiscord<iWonderAboutTuatara> like ever
18:43:18FromDiscord<Recruit_main707> its like syntactic sugar in this case, you are not getting the sequence values at compile time, you assign n and e to some information stored at some specific indexes of s (0 and 1 in this case)
18:43:24sschwarzerRika: But for someone new to Nim and its ecosystem, the "future" may be now already ;-)
18:43:40FromDiscord<Rika> what do you mean
18:43:51FromDiscord<iWonderAboutTuatara> @Recruit_main707 so basically macro doesn't know or care what s is, it's just grabbing whatever is it index whenever it's called?
18:45:07FromDiscord<Recruit_main707> yesnt, you are the one that should care about that
18:45:43FromDiscord<Recruit_main707> it will error at compile time if the compiler sees something isnt right though
18:45:43sschwarzerZachary: I like that Nim (to me) feels more high-level than C++, so IMHO it would totally make sense to have tooling "on the Nim level". "C-level" would only be needed when you're interfacing with C/C++ or are developing on the compiler and there's a problem with the code generation/execution.
18:46:05FromDiscord<haxscramper> You can do `` macro `..=`(lft : untyped, a : untyped) : untyped = `` to get type checking
18:46:10FromDiscord<Recruit_main707> but essentially, its what you said
18:46:20FromDiscord<haxscramper> `` macro `..=`(lft : untyped, a : seq) : untyped = ``
18:46:25FromDiscord<Zachary Carter> but we're compiling to C and C++ - so we're debugging C/C++ too at the end of the day
18:46:50FromDiscord<iWonderAboutTuatara> I see
18:46:51FromDiscord<iWonderAboutTuatara> thanks!
18:46:53Araqthat's a problem, not a feature
18:46:59FromDiscord<haxscramper> Or to be more accurate `seq | tuple | object | ref object` if you want to unpack `(12, 3)` and objects with `` proc`[]` `` too
18:47:05Araqbut at least we produce #line directives
18:47:09sschwarzerRika: Someone new to the ecosytem can't necessarily know whether better tooling is in the future or if it already exists.
18:47:14FromDiscord<iWonderAboutTuatara> never heard of `[]`
18:47:17disrupteki don't see any reason why we cannot surpass c debugging.
18:47:18FromDiscord<iWonderAboutTuatara> as a proc
18:47:28FromDiscord<Rika> i dont either
18:47:40FromDiscord<haxscramper> > as a proc↵@iWonderAboutTuatara https://nim-lang.org/docs/macros.html#%5B%5D%2CNimNode%2Cint
18:47:51FromDiscord<Zachary Carter> someone just needs to write a debugger 🙂
18:47:52FromDiscord<Rika> im just saying that expecting good refactoring for a language at this size/popularity is somewhat unreasonable
18:47:58sschwarzerZachary: That's like saying the CPython VM is written in C, so debugging Python with gdb (including the VM) would be reasonable.
18:47:58AraqI use 'getStackTrace' extensively and it's not available in C
18:48:02FromDiscord<iWonderAboutTuatara> oh index access is a macro?
18:48:02FromDiscord<Rika> but thats my opinion
18:48:08FromDiscord<Recruit_main707> yeah, if someone eiteher write exportc everywhere or create a debugger that uses a c debbugger but can read nim stacktraces
18:48:19FromDiscord<Zachary Carter> there's a difference
18:48:22FromDiscord<Recruit_main707> i kinda had a stroke there
18:48:47FromDiscord<Zachary Carter> you're forgetting about the python interpreter
18:48:56FromDiscord<Zachary Carter> that's what's written in C
18:49:06FromDiscord<Recruit_main707> > oh index access is a macro?↵@iWonderAboutTuatara its a proc
18:49:10FromDiscord<haxscramper> > oh index access is a macro?↵@iWonderAboutTuatara No, just a aregular proc. You can overload operators https://nim-lang.org/docs/tut1.html#procedures-operators
18:49:30FromDiscord<Recruit_main707> when you do `echo(s[1])`
18:49:38FromDiscord<Recruit_main707> you are calling `[]`
18:49:52Araqjust a minute ago I embedded getStackTrace in the produced C code as a comment to see where the produced C code comes from
18:50:10FromDiscord<iWonderAboutTuatara> @Recruit_main707 in your macro, what is `s`?
18:50:13Araqso in some cases we do surpass C++ already
18:50:19FromDiscord<iWonderAboutTuatara> side effect?
18:50:30disruptekyou can run a lot of nim code in the vm if you simply rename the file from nim to nims.
18:50:48Araqbtw, new record, 1:53
18:50:48disruptekbecause araq likes to make us rename files.
18:50:54sschwarzerZachary: I'm not sure I understand what you mean. What I meant is that Python programs (if executed with CPython) are processed by a C program, so you could (but IMHO shouldn't) debug your Python code by debugging the CPython interpreter and check what it's doing with your program. But of course you don't want to.
18:50:55FromDiscord<Recruit_main707> @iWonderAboutTuatara i didnt write any macro, i am talking about nim in general
18:51:12FromDiscord<iWonderAboutTuatara> no from earlier
18:51:12sschwarzersorry, should go to Rika
18:51:19FromDiscord<iWonderAboutTuatara> https://play.nim-lang.org/#ix=2zJt
18:51:20FromDiscord<Vindaar> oh, did you mean me @iWonderAboutTuatara? That was a typo on my end haha
18:51:24FromDiscord<Zachary Carter> Nim is compiled to C though - Python programs aren't
18:51:27FromDiscord<Zachary Carter> they're compiled to bytecode
18:51:28FromDiscord<Vindaar> just turned out to work in this case
18:51:29FromDiscord<iWonderAboutTuatara> oh might have been you
18:51:34sschwarzersorry, should indeed go to Zachary :-D
18:51:39FromDiscord<Vindaar> give me a sec
18:51:41FromDiscord<iWonderAboutTuatara> using a[`i`] gives illformed ast error
18:51:41FromDiscord<Rika> sschwarzer i think you misdirected
18:51:44FromDiscord<Recruit_main707> yep, it was him
18:51:46FromDiscord<Rika> yeah lol
18:51:46AraqZachary Carter: true but not very interesting
18:52:09FromDiscord<Vindaar> @iWonderAboutTuatara https://play.nim-lang.org/#ix=2zJw
18:52:10Araqwe used to have ENDB which added VM-like stuff to the produced C code
18:52:14FromDiscord<Recruit_main707> try with \`a`
18:52:19FromDiscord<Zachary Carter> I wasn't trying to be interesting - I was trying to explain why it's a different scenario
18:52:27Araqbut I couldn't maintain it
18:52:35Araqand it was really slow too
18:52:47FromDiscord<Zachary Carter> you can already have visual debugging with nim and gdb / lldb using VSCode
18:52:53FromDiscord<Vindaar> ahh
18:52:57FromDiscord<Zachary Carter> or Qt's code editor
18:53:15FromDiscord<Vindaar> I keep messing up, because I'm too hasty. Ok, 1 min and I actually run the code I write. Sorry for the confusion
18:53:33sschwarzerZachary: I know, but still I don't think it's unreasonable to think that somehow we could have debugging on the Nim level in the future. Nim has a certain semantics, so a debugger that looks at Nim on that level (independent of how the "semantics is executed") would make sense.
18:53:57Araqyes as I said, we had it, it was named ENDB
18:54:09FromDiscord<Vindaar> @iWonderAboutTuatara ok, here: https://play.nim-lang.org/#ix=2zJx
18:54:11FromDiscord<Recruit_main707> @iWonderAboutTuatara the \`XX` thing in macros and templates mean, dont write XX, but whatever XX is in your macro/template
18:54:22sschwarzerAraq: Sorry, I missed that.
18:54:22Araqam I muted to what...
18:59:52sschwarzerAraq: You said it was slow. What was the factor between "normal" Nim speed and execution under ENDB?
19:03:43nixfreakhow do you just get yyyy-mm-dd for getTime()?
19:06:04sschwarzernixfreak: Might make sense to use `now`, which you can format with `DateTime.format`.
19:06:24sschwarzerhttps://nim-lang.org/docs/times.html#parsing-and-formatting-dates
19:06:31Araqsschwarzer, factor of 10 but you pay roughly the same price with --stackTrace:on
19:06:52AraqENDB extended our stack traces with info about local variables etc
19:07:15sschwarzerAraq: For me a factor 10 wouldn't be bad if it's for debugging only.
19:07:41sschwarzerOf course there _could_ be situations where it's too slow.
19:07:42Araqtrue it was acceptable
19:07:46Araqhowever
19:08:38Araqit wasn't clear how to make it support multi-threading and it's changes the stack contents so much that you likely cannot debug a random crash with it
19:09:10Araq"my program crashes, let me fire up ENDB, great now it crashes somewhere else or not at all"
19:09:22sschwarzernixfreak: It looks like there's also `format` for `Time` objects
19:09:41sschwarzerAraq: I see
19:10:41Araqbetter patch the .elf debug sections for GDB
19:11:02Araqa much more fruitful approach
19:11:08sschwarzerWhat are the plans for the next Nim versions? I guess 1.4 will focus on arc/orc robustness?
19:12:00Araqyes, we also have "strict funcs" and view types though
19:13:46sschwarzerAraq: right, strict funcs are nice! :-) I've used them for a while, but had forgotten they're there. Probably because I had some time where I wasn't working with Nim. Also I had some problems, but if I remember correctly, these are all fixed now.
19:14:00Araqugh, why am I so bad? 11th out 11
19:14:04Araq*out of

19:22:12nixfreakok thanks
19:22:55sschwarzerIt's in the `times` module documentation, https://nim-lang.org/docs/times.html
19:28:55sschwarzer@all: What other programming languages do you like developing with, and why?
19:30:03*NimBot joined #nim
19:34:15Araqhow is that gonna produce an interesting result in #nim ?
19:34:37Araqand what does it matter, should we make Nim more like JS when many JS devs raise their hand?
19:34:49Araqanyhow, good night
19:35:02FromDiscord<Rika> i think theyre just asking a question
19:37:36sschwarzerRika: exactly, I'm just curious
19:37:58voidpisschwarzer: just nim & python for me
19:38:38sschwarzerAraq: I don't see why it should _not_ produce an interesting result. I guess most Nim devs are experienced devs and use more than one programming language.
19:39:01*thomasross joined #nim
19:39:21sschwarzerAraq: And for me, it's not about making Nim more similar to other languages (actually, I didn't even think of that). :)
19:40:15nixfreakif I'm subtracting dates I have to convert from string to int right
19:40:58sschwarzervoidpi: I'm using Python a lot (my "main" language since many years). I found Nim about a year ago and really like it. At the same time, I'm curious about other languages, especially for functional programming. But I'm kind of overwhelmed because there are so many options. *sigh*
19:41:29sschwarzernixfreak: Did you look at the module documentation I mentioned? :)
19:44:25sschwarzernxifreak: There doesn't seem to be a `Date` type, so I guess, you'd create two `DateTime` objects (maybe with the time set to 00:00 for clarity) and subtract them.
19:45:50nixfreakok , yeah I looked over them , There is a lot to unpack in the documentation
19:46:18sschwarzernixfreak: true, it has always happened to me that I just missed something which was actually there :)
19:46:32sschwarzersorry, not "always", but "sometimes" :)
19:47:14sschwarzer(maybe I wanted to write "actually", idk)
19:50:43sschwarzernixfreak: https://play.nim-lang.org/#ix=2zJO (don't try to execute this directly as Nim code though :-) )
19:51:07sschwarzerSo `parse` does the conversion (to `DateTime`) for you
19:54:55*sschwarzer quit (Quit: leaving)
19:57:19nixfreakoh ok , so you have to turn it into a DateTime object first then parse it
19:57:52nixfreakI tried doing this let bdate = initDateTime(04, mApr, 1980, 0, 0, 0)
19:57:52nixfreaklet dateNow = getTime()

21:12:55disruptekyou need something like cps.
21:13:01FromDiscord<Vindaar> I was always like "duh, if I have something that is implemened returning futures and stuff of course I can handle using async etc. But what to do when I _don't_". I guess then I don't do anything and keep using threads 🤣
21:13:21FromDiscord<Vindaar> disruptek so _that's_ what cps would actually solve?
21:13:30disruptekthat's one example, yes.
21:13:40disruptekcps gives you two ways to solve it:
21:13:51disruptekmove the continuation to a thread and run blocking code in that thread, or
21:13:52FromDiscord<Vindaar> ok, now suddenly I can understand your cps hype, haha
21:14:17disruptekput the continuation into an event queue and use select() or similar to poll for completion.
21:14:39FromDiscord<Vindaar> that's pretty neat. I always did the former manually when required

21:15:14FromDiscord<Vindaar> guess with that knowledge I'm gonna take a look at that repo again. Thanks!
21:15:25disruptekyeah, what it does isn't all that exotic.
21:16:00disruptekit's just, y'know, it rewrites your simple procedural code to this slightly more sophisticated abstraction.
21:17:45FromDiscord<Vindaar> I love it when things all of a sudden click into place, heh

22:55:22disruptekbut, jsonconvert is bad style. that's why it says "don't use this"
22:55:40FromDiscord<Elegant Beef> Doesnt a generic remove the abillity to use ufcs?
22:55:45disrupteki still think it's best suited to a template.
22:55:58disruptekwho cares about ufcs?

22:56:06disrupteksyntax isn't as important as semantics.
22:56:34disruptekwhen some knucklehead comes along and wants to extend this, it's harder than it should be.
22:58:13disrupteki think you have 1-2 templates of 2-3 lines each and then the user can add new types with one line.
23:02:57disrupteki think if my name was flegma, i'd change it.
