00:00:21FromDiscord<ElegantBeef> It doesnt hang, it just doesnt work
00:00:50FromDiscord<ElegantBeef> Like there is no error or anything it just runs the code flawlessly until i attempt to conver back from a string
00:01:57FromDiscord<Clyybber> can you echo the string?
00:02:01FromDiscord<ElegantBeef> Yea
00:02:15FromDiscord<Clyybber> might be worth putting echos there
00:02:22FromDiscord<Clyybber> to find out when exactly it begins to fail
00:02:51FromDiscord<ElegantBeef> It fails after the nim code is called but before returning to nimscript
00:03:58FromDiscord<ElegantBeef> Line 45 shows where it's not working
00:04:09FromDiscord<ElegantBeef> https://play.nim-lang.org/#ix=2Cfb
00:10:05FromDiscord<ElegantBeef> The interpreter just seems to silently fail
00:11:07FromDiscord<Clyybber> you sure its getInt ? Maybe its the type conversion
00:12:12FromDiscord<ElegantBeef> Yes without the conversion it also errors
00:13:34FromDiscord<ElegantBeef> Just double checked, doing `echo getInt(buff, pos)` results in the same behaviour
00:13:50*sealmove joined #nim
00:14:10FromDiscord<Clyybber> its probably the var param
00:14:58FromDiscord<ElegantBeef> It's being passed to a proc that isnt a var, though
00:15:24FromDiscord<Clyybber> I mean `pos` being a var param
00:15:37FromDiscord<Clyybber> maybe making it a local var fixes it
00:18:50FromDiscord<ElegantBeef> Nope
00:19:43FromDiscord<ElegantBeef> Replacing those with `0.T` doesnt crash
00:20:03FromDiscord<Clyybber> wdym?
00:20:24FromDiscord<ElegantBeef> replacing the `result = getInt` with `result = 0.T` works
00:20:39FromDiscord<ElegantBeef> So it's something with the VM calls was just ensuring that
00:20:59FromDiscord<Clyybber> is that playground example supposed to demonstrate the bug?
00:21:04FromDiscord<Clyybber> because it works fine for me
00:21:07FromDiscord<ElegantBeef> No
00:21:15FromDiscord<ElegantBeef> It relies on nimscripter
00:21:18FromDiscord<Clyybber> ok
00:21:23*mmohammadi9812 joined #nim
00:21:29FromDiscord<ElegantBeef> If you want to check it out i'll push this and you can clone the branch
00:21:37FromDiscord<Clyybber> aight
00:22:29FromDiscord<ElegantBeef> https://github.com/beef331/nimscripter/tree/speed
00:22:33FromDiscord<ElegantBeef> Dere you go
00:22:59FromDiscord<ElegantBeef> `nim c -r ./src/nimscripter` will run the `test.nims` file
00:23:14FromDiscord<ElegantBeef> And if you want to see the generated nimscript you can do `nim c -d:debugScript`
00:24:47*krux02 quit (Remote host closed the connection)
00:26:37FromDiscord<Clyybber> 141 is the line?
00:26:57FromDiscord<ElegantBeef> Yea
00:27:22FromDiscord<ElegantBeef> It's where as far as i can tell the VM silently fails
00:30:04FromDiscord<Clyybber> weird, getInt itself seems to get executed until the end
00:31:55FromDiscord<Clyybber> or am I stupid
00:32:04FromDiscord<ElegantBeef> I concur it runs to completion
00:32:22FromDiscord<ElegantBeef> The result seems ot be the issue
00:32:57FromDiscord<Clyybber> yeah discard works fine
00:33:16FromDiscord<ElegantBeef> hmm?
00:33:47FromDiscord<Clyybber> discard getInt(buf, pos)
00:34:03FromDiscord<Clyybber> it exits as soon as we pass its result to something else
00:34:07FromDiscord<Clyybber> like the type conversion
00:34:10FromDiscord<Clyybber> or echo
00:34:15FromDiscord<Clyybber> or assign it
00:40:18FromDiscord<ElegantBeef> Nothing stands out as obviously incorrect to me
00:41:02FromDiscord<Clyybber> maybe go into vm.nim and inspect the value there
00:41:13FromDiscord<Clyybber> I gotta get some sleep, cya
00:41:17FromDiscord<ElegantBeef> Buh bye
00:41:23FromDiscord<ElegantBeef> Thanks for the help anywho
00:46:49FromDiscord<ElegantBeef> @Clyybber Well thanks turns out there is a VmArgs.setResult for all the primitives
00:47:04FromDiscord<ElegantBeef> Didnt notice that previously and that works

01:41:12FromGitter<iffy> I have a thread running an asyncdispatch loop and other stuff is happening in another thread (worker). If I want the worker thread to cause things to happen in my asyncdispatch loop, is this a good architecture? Share a channel (or channels) between threads. Main thread registers an AsyncEvent and worker thread triggers the event when there's something in the channel for main to read.
01:43:27FromGitter<iffy> Or skip the AsyncEvent and just call tryRecv on the channel each time I poll()?

02:36:07FromDiscord<himu> quick query. how to do `let c: char = 'z'; var a: int = c - 'a';` in nim?
02:37:56*mbomba joined #nim
02:38:37FromDiscord<shashlick> just `var a = c.int - 'a'.int` should do it
02:39:02FromDiscord<shashlick> or you could see if {.borrow.} works
02:40:29FromDiscord<smallgram> For the JavaScript backend, is importjs and importcpp pragma basically the same?
02:48:35PrestigeHm if I create an object and write procs for + - * / does nim still evaluate equations correctly, or will they just be evaluated in left to right order?
02:55:24FromDiscord<Rika> afaik evaluation order does not change
02:55:33FromDiscord<Rika> theres a chart in the manual i think

10:32:15Yardanicosee e.g. https://gist.github.com/oltolm/1738289b5ac866ec6a7e4ef20095178e
10:32:19mipricast the ptr to a ptr UncheckedArray[T] of an appropriate T and then index into it
10:32:23Yardanicoor this^
10:32:37Yardanicothe thing I linked is pretty old
10:34:08FromDiscord<ShalokShalom> Can I replace keywords in Nim?
10:34:20PMunchWhat do you mean?
10:34:25PMunchLike rename `if`?
10:34:30FromDiscord<ShalokShalom> So use function instead of func and so on
10:34:37FromDiscord<ShalokShalom> Yes
10:34:51FromDiscord<ShalokShalom> With macros?
10:34:53PMunchI mean you can do this: https://nim-lang.org/docs/filters.html#available-filters-replace-filter
10:36:39FromGitter<gogolxdong> the link looks crazy.

10:46:30FromGitter<gogolxdong> Can pointer addition be treated as seq truncation?
10:46:36PMunchSpecial comment annotation?

10:46:55FromDiscord<ShalokShalom> The first line in your example
10:46:56PMunchOh, it's in the link I sent
10:47:08miprithat whole page of the documentation is about those
10:47:11miprithat was linked
10:47:53FromDiscord<ShalokShalom> oO
10:48:27FromDiscord<ShalokShalom> PMunch the sub and by keywords are explained
10:48:37FromDiscord<ShalokShalom> But I mean the #?replace thingy
10:49:00miprihttps://nim-lang.org/docs/filters.html <- the whole page is about that
10:49:00PMunchScroll up?
10:49:37FromDiscord<ShalokShalom> Ah, now I see. Thanks
10:50:43FromGitter<gogolxdong> that is treating a pointer type as a seq[T], I know char * is could be treated as string, which is seq[char]
10:50:55YardanicoPMunch: it's not hard to do something like that by hooking to Nim's lexer
10:50:59YardanicoI mean replaces like that
10:51:11Yardanicoit'll be a bit error-prone too, but less than replace
10:51:39mipriyou can't treat a random pointer as a seq[T], seqs have more than just their contents
10:52:06mipricstring -> string isn't free either
10:52:31FromDiscord<ShalokShalom> Yardanico How so less error prone?
10:52:50FromDiscord<ShalokShalom> How how does this look in the lexer?
10:52:52Yardanico@ShalokShalom if you use compiler's lexer, you can only replace occurences where it's actually a symbol and not a string literal
10:53:03Yardanicoe.g check out https://github.com/Yardanico/nuglifier where I replace stuff
10:53:08mipriyou can make it as 'good' as the C preprocessor at least
10:53:16Yardanicohttps://github.com/Yardanico/nuglifier/blob/master/src/nuglifier.nim#L57
10:53:24Yardanicobut of course the only real way is to modify nim's parser ;)
10:53:33Yardanico*syntax skins flashbacks*
10:55:55FromDiscord<ShalokShalom> Syntax skins existed in Nim?
10:56:16Yardanicoyes
10:56:48Yardanicothere was only one additional "skin" - braces
10:56:55Yardanicobut it was removed in 2017 because no one really used it
10:57:11Yardanicoand it increases the cost of the maintenance of the parser
10:57:16FromDiscord<Rika> ehem
10:57:39miprihttps://forum.nim-lang.org/t/2811 has an example
10:57:44FromDiscord<ShalokShalom> Same as in FSharp
10:57:55FromDiscord<ShalokShalom> They also offer both, keywords and indentation
10:58:01FromDiscord<ShalokShalom> And nobody uses the first.
11:00:02FromGitter<gogolxdong> I think it can't be treated as anything else when interoperating when C/C++ because memory layout, what about in pure Nim, I am not having any interoperability, just trying to translate pointer addition into native Nim operation, which produce the same result.
11:00:38Yardanico@gogolxdong just use UncheckedArray then
11:00:52Yardanicoyou know that C's "indexing operators" are just sugar over pointers, right?
11:01:07FromDiscord<ShalokShalom> I am a beginner and I find it hard to understand types in function declarations.
11:01:14Yardanico@ShalokShalom ??
11:01:22FromDiscord<ShalokShalom> Not in constants and such, just in proc and func and so on
11:01:32FromGitter<gogolxdong> yes , I know C pointer.
11:01:34Yardanicostill don't get it
11:01:45Yardanicoyou mean in "proc a(x: int)" it's hard to understand int?
11:01:53FromDiscord<ShalokShalom> Like, I don't know how to understand which types will come up and such.
11:01:59Yardanicowaty
11:02:00Yardanicowat*
11:02:16FromDiscord<ShalokShalom> I dont know how to define types pre-advance in types.
11:02:23FromDiscord<ShalokShalom> (edit) "types." => "functions."
11:02:30Yardanicoi don't get you at all, sorry
11:02:32FromDiscord<Rika> i dont understand what you mean
11:02:43PMunchI'm lost as well..
11:02:50miprihttps://play.nim-lang.org/#ix=2Che
11:02:54FromDiscord<Rika> maybe we dont understand because we are too used to doing it
11:03:05FromDiscord<haxscramper> Can you show what you are trying to do? Like maybe `F` code that you need to convert to nim?
11:03:16FromDiscord<haxscramper> Or nim code you are having troubles with
11:03:16FromDiscord<Rika> F-asterisk
11:03:16Yardanicowell nim isn't really unique in terms of procedures or proc argument
11:03:17Yardanicos
11:03:18FromDiscord<Rika> lol
11:03:33Yardanicoit's not really different from most other statically typed languages
11:03:44FromDiscord<ShalokShalom> In F# I dont need to specify them
11:03:51FromDiscord<ShalokShalom> This is my main issue here
11:04:03Yardanicowell, you'll need to get used to it :)
11:04:06FromDiscord<haxscramper> @Rika actually `F` does exist too. But let's assume it is just glob for language names
11:04:09FromDiscord<ShalokShalom> F# has complet type inferrence.
11:04:24FromDiscord<ShalokShalom> (edit) "complet" => "complete" | "inferrence." => "inference."
11:04:36FromDiscord<haxscramper> Well, you write function that operates on some kind of data, right? Generally speaking
11:04:40FromDiscord<Rika> you can just use `auto` everywhere
11:04:43FromDiscord<Rika> i guess
11:04:46Yardanicodon't
11:04:48FromDiscord<ShalokShalom> Oho?
11:04:51FromDiscord<haxscramper> No
11:04:52Yardanicoit's better to learn than to use auto
11:04:56FromDiscord<Rika> its not a great ide
11:04:57FromDiscord<Rika> (edit) "ide" => "idea"
11:04:58FromDiscord<ShalokShalom> Sad πŸ˜”
11:05:06FromDiscord<Rika> its a code smell and everyone's gonna hate you for it
11:05:07FromDiscord<Rika> lol
11:05:10FromDiscord<lqdev> this discussion again?
11:05:14Yardanicoyes
11:05:23Yardanicoidk, the concept of types seems very natural to me
11:05:24FromDiscord<haxscramper> Auto is basically `func [T0, T1, T2, T3]( ... )`
11:05:41FromDiscord<ShalokShalom> This all doesnt help
11:05:50FromDiscord<ShalokShalom> How to think about it?
11:05:50FromDiscord<Rika> well
11:05:59FromDiscord<Rika> its basically "just get used to it" i guess...
11:06:13FromDiscord<Rika> you can leave the types empty until you finish writing the function body
11:06:18FromDiscord<Rika> then add them
11:06:34Yardanico@ShalokShalom well, it's really natural
11:06:47FromDiscord<haxscramper> Idk, maybe you just need example of how to rewrite ML-like to nim? To understand the difference
11:06:53FromDiscord<Rika> most of us here already know what types should go onto parameters before we even know what the function body should look like so we really cant help
11:06:55FromDiscord<haxscramper> E.g. example
11:07:04miprigive the language a chance, as it is, and see how you like it after a bit. starting with how you can change the language to be more like one you already know is, at the least, delaying your learning the language as it is. and at the worst you'll run into crazy problems that only occur in your new variant of the language
11:07:12FromDiscord<ShalokShalom> @Rika And how do you know that?
11:07:16miprilike, maybe auto-everywhere Nim has really horrible compiler performance. who would know?
11:07:19FromDiscord<Rika> i dont know, experience?
11:07:23FromDiscord<ShalokShalom> @mipri I already tried three times
11:07:26FromDiscord<Rika> programming for years needing to put the types?
11:07:40FromDiscord<ShalokShalom> So how to start?
11:07:47Yardanicoby simple programs
11:07:53Yardanicomake a procedure to sum two INTEGERS
11:07:54Yardanicotwo numbers
11:07:58Yardanicomathematical functions etc
11:08:02Yardanicostrings
11:08:21FromDiscord<ShalokShalom> I dont like to think about that pre-advance
11:08:25Yardanicoyou don't have to
11:08:29FromDiscord<ShalokShalom> I can think about it later
11:08:31Yardanicoyou can write the function and then the types
11:08:39FromDiscord<ShalokShalom> Aha, ok?
11:08:47FromDiscord<ShalokShalom> And substitute with auto?
11:08:48FromDiscord<haxscramper> http://loup-vaillant.fr/tutorials/earley-parsing/parser.ml -> https://play.nim-lang.org/#ix=2yDb basically 1:1 rewrite of ocaml to nim
11:08:50Yardanicono
11:08:56Yardanico@ShalokShalom write the function, and then place types
11:09:04FromDiscord<Rika> thats what i said....
11:09:10Yardanicoit's not uncommon to change arguments of a function while you're writing it
11:09:19FromDiscord<ShalokShalom> Ah, ok
11:09:19FromDiscord<ShalokShalom> Super
11:09:20FromDiscord<Rika> > you can leave the types empty until you finish writing the function body
11:09:22FromDiscord<Rika> 😦
11:10:19FromDiscord<ShalokShalom> Ah, I can make untyped? πŸ₯³
11:10:24FromDiscord<ShalokShalom> And add later.
11:10:59FromDiscord<Rika> you cant run it without types of course
11:11:20FromDiscord<ShalokShalom> What is the benefit of choosing C++ as compilation target instead C?
11:11:31FromDiscord<Rika> exceptions are faster AFAIK
11:11:45FromDiscord<ShalokShalom> I dont seem to find any docs on auto and untyped yet.
11:11:48FromDiscord<Rika> i dont know any other benefits other than that but i think there are more

11:15:43FromDiscord<ShalokShalom> Is the forum stable now?
11:15:48FromDiscord<Yardanico> ??
11:15:50FromDiscord<Yardanico> it's always been "stable"
11:15:55FromDiscord<ShalokShalom> I experienced couple of issues about a year ago
11:16:03FromDiscord<ShalokShalom> With sites not loading and so on.
11:16:15FromDiscord<ShalokShalom> So hiccup free now?

11:16:32*TomDotTom joined #nim
11:16:43FromDiscord<Rika> nothing is truly hiccup free
11:17:02miprishit happens. Shit hasn't happened recently.
11:18:03FromDiscord<ShalokShalom> Is Nim suitable as a first language?
11:19:01FromDiscord<haxscramper> I think yes, it is good enough as a first language
11:19:34FromDiscord<haxscramper> Also see: https://www.reddit.com/r/nim/comments/jdcu21/is_nim_good_for_beginner_programmers/
11:19:53FromDiscord<rc-05> @ShalokShalom Well yes, it has python-like syntax so it's readable unlike Rust and C++
11:20:02FromDiscord<Rika> i think its still hard if you have no one to ask questions to
11:22:42miprithe single most beneficial quality for a language being good as a first language, is it having a community that will look at your entire pasted program and tell you that you had a typo, or who can read the compiler's error message back to you with emphasis.
11:23:05mipriNim has play.nim-lang.org and these chats, so it suffices.
11:23:56FromDiscord<Rika> well most people wont check the chats
11:24:10mipripeople debating the finer points of a language being good/bad are fooling themselves about how difficult programming is overall.
11:26:19FromDiscord<rc-05> @Rika There's still the manual if you are not sure for how something is done and luckily IDE integration is not bad for Nim
11:26:38FromDiscord<ShalokShalom> I like all of this
11:30:13FromGitter<gogolxdong> Does UncheckedArray need alloc and free memory manually?
11:30:27miprino, neither
11:30:28FromDiscord<Rika> yes
11:30:31FromDiscord<Rika> wait huh?
11:30:38FromDiscord<Rika> oh you mean converting to UA? no
11:31:08mipriyeah casting to it for ptr arithmetic, as in https://play.nim-lang.org/#ix=2Che
11:32:32FromDiscord<Rika> yeah dont dealloc it
11:33:28FromGitter<gogolxdong> Will an UncheckedArray[T] field of object type grow/shrink or just used as casting?
11:33:43mipriit's unchecked, it doesn't even know what its length is
11:33:47FromDiscord<Rika> just use for casting
11:34:04FromDiscord<Rika> its like pointer used as array in c
11:34:05mipriwith experimental view types you can have openArray[T] in a field with a length
11:35:17FromGitter<gogolxdong> sizeof an object with UncheckedArray field is 1.
11:36:14FromDiscord<Rika> because its a pointer
11:36:16FromDiscord<warcrimecommiter1337> piss and fart
11:36:21FromDiscord<Rika> oh, 1
11:36:23FromDiscord<Rika> thats weird
11:36:23mipriyou probably want a ptr UncheckedArray[T] field. that'll have a sizeof of 8
11:36:27*luis_ joined #nim
11:36:28FromDiscord<ShalokShalom> Hnn, there are a lot of examples in the documentation who dont run since they are incorrectly indented.
11:36:34FromDiscord<Yardanico> for example?
11:36:36FromDiscord<Rika> @ShalokShalom examples?
11:36:53FromDiscord<ShalokShalom> https://nim-lang.org/docs/options.html#some%2CT
11:37:07FromDiscord<Rika> its not incorrectly indented
11:37:08FromDiscord<Yardanico> how is it incorrectly indented?
11:37:20FromDiscord<Yardanico> it's actually being checked, it's a runnableExamples - https://github.com/nim-lang/Nim/blob/version-1-4/lib/pure/options.nim#L108
11:37:22FromDiscord<warcrimecommiter1337> shit, even
11:37:28FromDiscord<ShalokShalom> https://play.nim-lang.org/#ix=2ync
11:37:29FromDiscord<Rika> https://play.nim-lang.org/#ix=2Chk
11:37:30FromDiscord<Rika> works here
11:37:41FromDiscord<Yardanico> @ShalokShalom ??
11:37:50FromDiscord<Yardanico> your snippet wrosk
11:37:51FromDiscord<Yardanico> (edit) "wrosk" => "works"
11:37:57FromDiscord<Rika> yes
11:38:20FromDiscord<ShalokShalom> Oh, this is after I edited it
11:38:24FromDiscord<ShalokShalom> Wait a second
11:38:46miprijust point to the example in the documentation
11:40:12mipriwhat you might be running into is that "incorrect indentation" is an answer you'll readily get from indentation-unrelated syntax errors. If you're pasting a bunch of examples into the same file, you might've broken syntax earlier, or the examples may not all work right next to each other.
11:40:38FromDiscord<Yardanico> yeah, sometimes the compiler gives you "incorrect indentation" errors when you have invalid code
11:40:40mipribut it's definitely not the case that there are lots of examples in the docs that don't work because they're incorrectly indented.
11:40:42FromDiscord<Yardanico> but not invalid indentation
11:40:53FromDiscord<Yardanico> yeah, most examples nowadays are checked with runnableExamples
11:40:55FromDiscord<Yardanico> so they're tested
11:41:10FromDiscord<ShalokShalom> @Yardanico runnableExamples gets checked when the website gets build?
11:41:15FromDiscord<Yardanico> when docs are built
11:41:37FromDiscord<Yardanico> and it's a part of CI
11:41:41FromDiscord<Yardanico> so it's checked for every commit
11:42:00FromDiscord<ShalokShalom> Now it works
11:42:11FromDiscord<ShalokShalom> I think its an issue with the new mobile Firefox
11:42:25*luis_ quit (Remote host closed the connection)
11:42:34FromDiscord<ShalokShalom> It has a new renderer and makes a lot of issues in online code editors
11:43:09FromDiscord<ShalokShalom> Can I saw that I want the type inference in bindings happen to be left associated?
11:44:23FromDiscord<ShalokShalom> const name = 1 becomes type 'name'
11:44:29FromDiscord<Yardanico> what
11:44:30FromDiscord<ShalokShalom> (edit) "becomes" => "↡becomes"
11:44:39FromGitter<gogolxdong> https://play.nim-lang.org/#ix=2Chm can this auto-generated snippet be replaced with a native operation, I think it essentially grows an buffer, and add p_payload by delta.
11:44:48FromDiscord<ShalokShalom> !eval name = 1
11:44:50NimBotCompile failed: /usercode/in.nim(1, 1) Error: undeclared identifier: 'name'
11:45:00FromDiscord<ShalokShalom> !eval const name = 1
11:45:07NimBot<no output>
11:45:21FromDiscord<ShalokShalom> I want that to be the type of the key, automatically
11:45:28FromDiscord<Yardanico> i don'
11:45:31FromDiscord<Yardanico> (edit) "don'" => "don't get you again :("
11:45:32FromDiscord<ShalokShalom> Instead the primitive on the right side.
11:45:53mipri!eval const name = 1; echo name.typeof
11:45:55NimBotint
11:46:02FromDiscord<ShalokShalom> Yeah
11:46:16PMunchAnd what type do you want it?
11:46:19FromDiscord<ShalokShalom> Can I auto-infer this as type name instead int?
11:46:31FromDiscord<Yardanico> AAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
11:46:36FromDiscord<Rika> no, you have to explicitly declare distinct types
11:46:38FromDiscord<ShalokShalom> I want to precise my types, so to not use a lot of ints
11:46:46FromDiscord<ShalokShalom> @Rika I want to change that.
11:46:57FromDiscord<ShalokShalom> Like, by default always the left side.
11:47:02PMunchYou can set up a macro for it
11:47:04miprithis is, at least, something that a template can probably do for you.
11:47:07FromDiscord<Yardanico> sent a code paste, see https://play.nim-lang.org/#ix=2Chn
11:47:19FromDiscord<ShalokShalom> πŸ₯³
11:47:30FromDiscord<ShalokShalom> Thats really amazing
11:47:51FromDiscord<Rika> it's not as easy as F# sure, but its at least doable πŸ˜›
11:48:05FromDiscord<ShalokShalom> Nim is way more flexible than F#
11:48:10FromDiscord<Rika> i think in some languages its much more janky to do than in nim
11:48:21FromDiscord<ShalokShalom> Its just less capable on the issue of type inference.
11:48:35mipridoes F# really have anything like this? OCaml doesn't have it
11:48:39FromDiscord<ShalokShalom> The flexibility of Nim is unmatched
11:49:03FromDiscord<ShalokShalom> No, I dont think so, macros are not really a thing in FSharp I think
11:49:34FromDiscord<ShalokShalom> Lisp comes close to Nim, but I have yet to find another language that is so capable with its macro system
11:49:42FromDiscord<Rika> @ShalokShalom its matched (actually beaten) by lisp afaik, but you tell me how fun you find programming in lisp :PPP
11:50:15FromDiscord<ShalokShalom> Yeah, I know lisp a little bit
11:50:28FromDiscord<ShalokShalom> And actually, the new version of Racket will be indentation based.
11:50:34FromDiscord<Rika> that's funky
11:50:38FromDiscord<Rika> radical change
11:50:42FromDiscord<Rika> feel like many lispers will hate on it
11:50:42FromDiscord<ShalokShalom> Yeah 😎
11:51:21FromDiscord<ShalokShalom> So, I have seen a video of one of the maintainers, who explains it
11:51:33FromDiscord<rc-05> @Rika Hey don't you like all these parenthesis?
11:51:37FromDiscord<ShalokShalom> Racket is always an educational language, so they justify it by that.
11:52:15FromDiscord<Rika> lmao
11:52:29FromDiscord<Rika> most people say its abstracted away by the IDE and i get it
11:52:45FromDiscord<Rika> but its not uncommon for many programmers to edit on stock vim
11:52:51FromDiscord<ShalokShalom> Yeah, but you need to get used to it
11:53:01FromDiscord<ShalokShalom> They say, after 6 months, you dont see it anymore
11:53:07FromDiscord<Rika> thats a long time...
11:53:18FromDiscord<ShalokShalom> But first: I dont like to go through these 6 months, exactly
11:53:41PMunch@ShalokShalom: https://play.nim-lang.org/#ix=2Chp
11:53:49FromDiscord<ShalokShalom> And second: Why put them there, when you dont see them afterwards, and this is a desirable thing
11:54:13FromDiscord<Rika> pmunch: cant you also move the type definition into the macro?
11:54:16FromDiscord<Rika> or is that not gonna work
11:54:25PMunchSure
11:54:31FromDiscord<Rika> i guess its more work
11:54:37PMunchNot really
11:54:44FromDiscord<Rika> i guess its "implementation is up to the reader"
11:54:49FromDiscord<Rika> πŸ˜›
11:54:57PMunchhttps://play.nim-lang.org/#ix=2Chq
11:55:00FromDiscord<ShalokShalom> This is awesome
11:55:10FromDiscord<ShalokShalom> I still like to have that build in
11:55:23FromDiscord<ShalokShalom> Without specifying it always
11:55:33FromDiscord<ShalokShalom> Just evaluate the type according to the name
11:55:44FromDiscord<ShalokShalom> I guess this takes a more invasive approach?
11:55:47PMunchOr if you want to allow all types, not just distinct ints: https://play.nim-lang.org/#ix=2Chr
11:55:53FromDiscord<Rika> not sure what you mean by invasive
11:56:08PMunchIf it was the default pretty much all Nim code would break :P
11:56:17FromDiscord<Rika> and its not really desired
11:56:18FromDiscord<ShalokShalom> Well, changing actually the type inference
11:56:25PMunchlet x = 10, 10 would now be a distinct int named x
11:56:31FromDiscord<Rika> i dont think a lot of us nimions want something like this
11:56:32FromDiscord<ShalokShalom> @PMunch Yeah, but just for me, like with a build trigger
11:56:37FromDiscord<Yardanico> @Rika exactly
11:56:45FromDiscord<ShalokShalom> I want distinctive tyoes
11:56:54FromDiscord<Rika> most of us dont which is why its not in the stdlib
11:57:07FromDiscord<Rika> but hey, you have this macro now
11:57:08FromDiscord<Yardanico> @ShalokShalom so declare them explicitly :)
11:57:12FromDiscord<Rika> you can just put this in a util file and use it
11:57:13FromDiscord<ShalokShalom> I dont see the sense in 40 different string types, which are not supposed to be mixed, but its still possible to do so
11:58:08FromDiscord<ShalokShalom> @Yardanico I do like this in my code without noise.
11:58:15PMunchBut now you need to name your variables the same as whatever the arguments of your procedures accept
11:58:17FromDiscord<ShalokShalom> @Rika util file?
11:58:19FromDiscord<Yardanico> "noise" is very subjective
11:58:20PMunchWhich can get confusing
11:58:38FromDiscord<ShalokShalom> @PMunch Sure?
11:58:40miprithere will be noise though, because once you use these distinct types you're going to be constantly stripping the type
11:58:44FromDiscord<ShalokShalom> I havnt done this yet.
11:58:58mipriit's going to be name.int, thing.int, something.int all over
11:59:09FromDiscord<ShalokShalom> Isnt mixing dozens of different ints potentially dangerous?
11:59:15FromDiscord<Rika> @ShalokShalom like in whatever library you're developing, you'd put this in some file called "util.nim" that everything else imports, or something like that
11:59:24FromDiscord<Rika> > Isnt mixing dozens of different ints potentially dangerous?↡not necessarily
11:59:27FromDiscord<Rika> to a point it is
12:00:03FromDiscord<Rika> but if you're careful enough it wont, like using distinct ints for not literally all variables, but only for distinctly different variables
12:00:24FromDiscord<Rika> so something like measurements in metres can be one distinct int and inches can be another
12:00:33FromDiscord<Rika> many vars can be in metres, same for inches
12:00:36FromDiscord<ShalokShalom> Aah, ok
12:00:40FromDiscord<Rika> but its fatal to mix them
12:00:44FromDiscord<ShalokShalom> So I can name this how I want.
12:01:06PMunchI mean I could get behind implicitly creating distinct types when you define a type with a variable that doesn't exist
12:01:15FromDiscord<ShalokShalom> @mipri Thats confusing indeed.↡↡Is there a way around this?
12:01:19FromDiscord<Yardanico> no
12:01:21FromDiscord<Yardanico> it's intended
12:01:25FromDiscord<Yardanico> Nim has a strict type system
12:01:27FromDiscord<Rika> that's the point of distinct ints
12:01:29PMunchSo `var distance: Meter = 10` creates Meter if it doesn't already exist
12:01:31FromDiscord<Yardanico> you can work around it with converters
12:01:37FromDiscord<Rika> so you dont just mix it with another int
12:01:38FromDiscord<Yardanico> but then you lose the whole point in distinct types
12:01:48FromDiscord<ShalokShalom> And why do primitive types that not?
12:01:51FromDiscord<Yardanico> ?
12:02:00FromDiscord<Rika> > And why do primitive types that not?↡wdym? i didnt understand
12:02:17FromDiscord<ShalokShalom> Can I not infer strings and such as what they are, and then put my distinctive type over it?
12:02:26FromDiscord<Rika> i uh
12:02:30FromDiscord<Rika> dont get it still
12:02:31FromDiscord<Rika> sorry
12:02:46FromDiscord<Rika> i assume its hard for us who didnt come from highly functional languages
12:02:52FromDiscord<Rika> to understand, i mean
12:03:27miprimy internal time-series graphs of "what on EARTH are you talking about" are getting pretty entertaining to look at
12:03:33FromDiscord<Yardanico> exactly
12:03:52mipriFP langs don't use a lot of distinct types, that's more of an Ada thing
12:04:05FromDiscord<Yardanico> @ShalokShalom maybe you should just accept that nim is an imperative language at its core
12:04:12FromDiscord<ShalokShalom> Nooooo
12:04:28FromDiscord<Yardanico> of course you can do functional and stuff, but the language isn't made specifically for that
12:04:30FromDiscord<Rika> mipri: i mean nim is kinda inspired by ada i think..... xd
12:04:35FromDiscord<ShalokShalom> func is pure
12:04:43FromDiscord<ShalokShalom> Not even F# has that
12:04:43FromDiscord<Idefau> same
12:04:49FromDiscord<ShalokShalom> Almost no language does
12:04:55FromDiscord<ShalokShalom> So, fresh from the start
12:05:05FromDiscord<ShalokShalom> int, string and so on are primitive types
12:05:18FromDiscord<Yardanico> "func" is not 100% pure either ;)
12:05:24FromDiscord<ShalokShalom> Appearently, they behave differently in certain cases
12:05:26FromDiscord<Yardanico> you can do "var int" just fine
12:05:28FromDiscord<Idefau> func is useful for math stuff but its not like it makes nim functional
12:05:30FromDiscord<Yardanico> in afunc
12:05:34FromDiscord<Yardanico> @Idefau exactly
12:05:36FromDiscord<ShalokShalom> @Yardanico 1.4 catched the last edge case?
12:05:46FromDiscord<Yardanico> @ShalokShalom no, "var int" and similar is allowed
12:05:46FromDiscord<ShalokShalom> I got told.
12:05:48FromDiscord<Yardanico> explicitly
12:06:02*supakeen quit (Quit: WeeChat 2.9)
12:06:02FromDiscord<ShalokShalom> Within a func?
12:06:03FromDiscord<Yardanico> 1.4 with strictFuncs is for deep immutability with refs unless you specify that you want to mutate them explicitly
12:06:10FromDiscord<Yardanico> @ShalokShalom yes
12:06:15FromDiscord<Yardanico> I mean in the arguments
12:06:17FromDiscord<ShalokShalom> Yeah, and I heard this is the last edge case
12:06:21FromDiscord<Yardanico> it's not an edge case
12:06:25FromDiscord<Yardanico> it's explicitly allowed
12:06:28FromDiscord<ShalokShalom> πŸ™„
12:06:33*supakeen joined #nim
12:06:40miprivar in func has nothing to do with the purity of the function, but with the FPness of it
12:07:10mipriyou can write an imperative loop that mutates an index across an array
12:07:23mipribut it doesn't have side effects.
12:07:48FromDiscord<ShalokShalom> Thats fine
12:07:52FromDiscord<ShalokShalom> puh
12:07:58FromDiscord<ShalokShalom> I just want it pure
12:08:12FromDiscord<ShalokShalom> So, fresh: primitive types are dangerous
12:08:17FromDiscord<ShalokShalom> (To me)
12:08:17FromDiscord<Rika> you can always not make it var anyway
12:08:22FromDiscord<ShalokShalom> I dont wanna mix that
12:08:35FromDiscord<Rika> > So, fresh: primitive types are dangerous↡how so...
12:08:36FromDiscord<ShalokShalom> And I dont see the sense in a type system, that encourages us to do so
12:08:41Yardanicoaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
12:08:42FromDiscord<Idefau> i am primitive
12:09:07FromDiscord<Yardanico> @ShalokShalom efficiency is the main Nim's goal
12:09:16FromDiscord<Yardanico> primitive types are the best for performant code
12:09:24FromDiscord<Rika> im really sorry but i think a lot of us have a different opinion from you
12:09:25FromDiscord<ShalokShalom> @Rika Since mixing types is dangerous whenever that is unintentional
12:09:26FromDiscord<Yardanico> not some boxed ints, but pure ints
12:09:39FromDiscord<ShalokShalom> How is mixing two completely unrelated numbers senseful?
12:09:41FromDiscord<Yardanico> @ShalokShalom the compiler just won't compile if you're "mixing types" when you can't do that
12:09:46FromDiscord<ShalokShalom> That counters the sense of types
12:09:47FromDiscord<Yardanico> @ShalokShalom they're both numbers
12:10:00narimiranend of 2020 and you guys still feed trolls? c'mon
12:10:09FromDiscord<Rika> i dont think he's a troll
12:10:14FromDiscord<Idefau> i am troll food
12:10:17FromDiscord<Rika> just someone with a massive difference in opinion
12:10:19FromDiscord<ShalokShalom> But age and the amount of money on my bank account is supposed to be mixed?
12:10:20mipriI think he is, but don't worry about it.
12:10:29FromDiscord<Yardanico> @ShalokShalom you can use distinct types for this
12:10:33FromDiscord<Rika> you can do it
12:10:35FromDiscord<Rika> just explicitly
12:10:36FromDiscord<Yardanico> but you don't want to use them for EVERYTHING
12:10:43FromDiscord<Rika> also can always do it with a macro
12:10:45FromDiscord<Rika> but yeah
12:10:52FromDiscord<Rika> its not a great idea to do it for everything
12:10:56FromDiscord<ShalokShalom> Why is it not helpful?
12:10:59FromDiscord<Rika> there should be a limit to it
12:11:12FromDiscord<Idefau> make a DSL that is entirely functional
12:11:17FromDiscord<Idefau> somehow
12:11:19FromDiscord<Idefau> B)
12:11:21FromDiscord<ShalokShalom> Isnt that like saying I dont want static types always and dynamic ones are a good default?
12:11:25FromDiscord<Rika> i have to go, i really dont want to get stressed over a conversation again, sorry again
12:11:34mipri"oh you're adding apples and oranges there. it doesn't make sense." -> "ok fine, I am now adding apples.fruit and oranges.fruit, and getting a fruit. Now it makes sense." the end result is a lot of noise that makes it easy for actual, serious bugs to slip through because the code is physically harder to follow.
12:11:35FromDiscord<Yardanico> yeah me too :P
12:11:36FromDiscord<Clyybber> @ShalokShalom sup, whats the question?
12:11:42FromDiscord<ShalokShalom> Hi
12:12:27FromDiscord<ShalokShalom> So, I am not a troll
12:12:50FromDiscord<ShalokShalom> I am just interested into what I think makes sense and strict type systems are that, as an example
12:12:57FromDiscord<Yardanico> but your phrasing is very very very hard to understand for other people
12:13:00FromDiscord<Yardanico> and your arguments as well
12:13:04FromDiscord<ShalokShalom> I have the feeling primitive types counter that idea.
12:13:13FromDiscord<Idefau> same
12:13:18FromDiscord<ShalokShalom> Yeah, probably because I dont have the experience
12:13:21FromDiscord<ShalokShalom> Not on purpose
12:13:29FromDiscord<Yardanico> @ShalokShalom when needed, you can use "distinct int"
12:13:38FromDiscord<Yardanico> but in most cases "int" is just enough
12:14:00FromDiscord<ShalokShalom> But isnt it that in large code bases, its easy to mix types unintentionally
12:14:03miprior you can lean on range types, to be more like Ada
12:14:13FromDiscord<ShalokShalom> And isnt this, why we have compile time type checking
12:14:18FromDiscord<Yardanico> @ShalokShalom you can't mix int with a distinct int
12:14:23FromDiscord<ShalokShalom> @mipri Range types?
12:14:32FromDiscord<Yardanico> yes, range types
12:14:35FromDiscord<Yardanico> the manual exists :)
12:14:44FromDiscord<ShalokShalom> @Yardanico Yeah, but why cant I use distinctive types by default?
12:14:47FromDiscord<Yardanico> https://nim-lang.org/docs/manual.html#types-subrange-types
12:14:58FromDiscord<ShalokShalom> I thought that is a concept
12:14:59FromDiscord<Clyybber> @ShalokShalom distinct types by default don't make sense
12:15:03narimiranuse them by default, who's stopping you? :D
12:15:11narimiran(in your code, that is)
12:15:18FromDiscord<ShalokShalom> Not an actual implementation
12:15:24FromDiscord<Clyybber> I know what you are getting at, since last time you wanted each variable to have its own type
12:15:30narimiranlol
12:15:36FromDiscord<Yardanico> and previously he wanted to not have types at all :)
12:15:38FromDiscord<Idefau> lol you pinged someone else
12:15:45FromDiscord<ShalokShalom> @mipri I actually love that πŸ‘€
12:15:49Yardanico@idf: old
12:15:53Yardanicoidk why it pinged in this case though
12:15:55FromDiscord<ShalokShalom> It shows exactly, what it is doing.
12:15:56Yardanicothe new rule is pretty clear
12:16:00Yardanicotest yardanico
12:16:00FromDiscord<ShalokShalom> I like that
12:16:01mipri!eval var x: range[0..5]; echo (x.typeof.low, x.typeof.high)
12:16:04NimBot(0, 5)
12:16:28FromDiscord<Clyybber> @ShalokShalom IMO you are confusing a type system with a symbol system
12:16:45FromDiscord<Clyybber> Computation is mixing different symbols in most languages
12:16:50FromDiscord<ShalokShalom> @Yardanico No, I wanted proper type inference that covers all the code.
12:17:18FromDiscord<Yardanico> yes, and "type annotations are bad"
12:17:18FromDiscord<Clyybber> take a look at crystal, it has global type inference
12:17:18FromDiscord<ShalokShalom> @[email protected] I dont know how
12:17:31narimiranstart by reading the manual and tutorials
12:17:32FromDiscord<Yardanico> maybe learn Nim a bit first? :)
12:17:35FromDiscord<Clyybber> but no language that I know of has implemented "each symbol has its own type"
12:17:43narimiranand leave worries for later
12:17:47FromDiscord<ShalokShalom> @Yardanico Thanks. I am more looking for something else, I think
12:17:48FromDiscord<Clyybber> because its a unneccessary sophistication
12:17:52mipritype annotations in function signatures help a lot to prevent errors, meanwhile.
12:18:49FromDiscord<ShalokShalom> @Clyybber I would then default to specify those, which I like to have a different type
12:18:59FromDiscord<ShalokShalom> So its just a default.
12:19:10FromDiscord<Clyybber> So var a has type A
12:19:13FromDiscord<Clyybber> and var b has type B
12:19:15narimiranmaybe you need some other language....
12:19:33FromDiscord<Clyybber> whats the purpose
12:19:40miprinarimiran: not many languages allow this though: https://play.nim-lang.org/#ix=2Chp
12:19:45FromDiscord<ShalokShalom> @Clyybber No, they dont have a complete type inference either. And they also lack indendation based block building and Godot bindings, as well as compiling to C
12:20:05narimiranmipri: yeah, but nothing is good enough for him
12:20:11FromDiscord<ShalokShalom> @Yardanico I just prefer to read them in my IDE and F# does that successfully
12:20:12narimiran*them
12:20:18FromDiscord<Clyybber> @ShalokShalom there is no complete type inference
12:20:28FromDiscord<ShalokShalom> Tons of researchers and mathematics use it that way.
12:20:32FromDiscord<Clyybber> at some point you have to tell the programm a type
12:20:39FromDiscord<ShalokShalom> Type annotations are entirely optional
12:20:42FromDiscord<Yardanico> @ShalokShalom no
12:20:49FromDiscord<Yardanico> somewhere in the stdlib types are actually there
12:21:04FromDiscord<Yardanico> but for user code it might be "optional" because the compiler can figure it out based on other libraries you're using
12:21:07FromDiscord<Yardanico> which HAVE type annotations
12:21:43narimiranyeah yeah, type annotations are noise, but stuff like "System.IO.File.ReadAllText" is not
12:21:43mipriand if F# is like OCaml in this respect, modules still have types, and module definitions get pretty detailed
12:21:46FromDiscord<Idefau> see all these problems come from the very definition of a variable↡just use stacks for everthing
12:21:53FromDiscord<Idefau> (edit) "stacks" => "the stack"
12:22:02FromDiscord<ShalokShalom> @Clyybber FSharp makes type annotations completely optional and so does any other ML and Haskell like language, most of them just choose to do them as a convention.
12:22:02narimiran"Array.filter" is not noise
12:22:27narimiran"Seq.sort >> System.String.Concat" is not noise
12:22:27FromDiscord<Yardanico> @ShalokShalom but it knows that number is a number
12:22:28FromDiscord<Yardanico> and not a string
12:22:32FromDiscord<Clyybber> @ShalokShalom Because you are providing literals, which the types trickle down from
12:22:37FromDiscord<ShalokShalom> @mipri Modules are at least not higher order in F#, idk how else they are different
12:23:09FromDiscord<Clyybber> but I'm not sure what your proposal is
12:23:26miprinot as a 'convention', but as a practical consideration. If there were no explicit types at all anywhere in the language, then a newly introduced bug that you just typed could result in an error message, not in your code, but deep in some core stdlib library
12:23:33FromDiscord<ShalokShalom> @Yardanico No. You really dont know what a HM type system is.
12:23:40FromDiscord<Yardanico> I do
12:23:46FromDiscord<Yardanico> and it still some kind of a source
12:23:52narimiranend of 2020 and you guys still feed trolls? c'mon
12:24:07mipri2020 isn't over yet. This is at least not as hellish as the outdoors.
12:24:11FromDiscord<Yardanico> yeah sorry i'll stop
12:24:45FromDiscord<Idefau> when 2020 ends i will restart it for my own pleasure
12:24:51mipriI just hope I won't be saying in a few years, "don't worry, the decade will be over one day"
12:25:01miprilet's keep this shit fully contained in 2020
12:25:04FromDiscord<ShalokShalom> @Clyybber I dont propose anything
12:25:12narimiranthis decade ends in ~2 months ;)
12:25:24mipriwhat, are you counting from 1? heretic
12:25:31FromDiscord<Idefau> why yes the month 0
12:25:36narimiranyes, discussing about year 0 and year 1 is more productive than the stuff above
12:25:53FromDiscord<Clyybber> !echo 0x2b or not 0x2b
12:25:55narimiranmipri: so, you're still in 2019?
12:26:10FromDiscord<Clyybber> !eval echo 0x2b or not 0x2b
12:26:12NimBot-1
12:26:17FromDiscord<Clyybber> thanks idf
12:26:20FromDiscord<Idefau> np
12:26:39FromDiscord<Idefau> !eval echo 0x2be or not 0x2be
12:26:41miprihmm ... there was some language that recently removed the ability to change which index arrays start at ...
12:26:41NimBot-1
12:27:24FromDiscord<ShalokShalom> sent a long message, see http://ix.io/2Chy
12:27:35FromDiscord<ShalokShalom> These two ints are not meant to be mixed.
12:27:37FromDiscord<Idefau> const birthday: DateInt
12:27:39FromDiscord<Clyybber> you give them different types
12:27:41FromDiscord<Yardanico> @ShalokShalom we answered
12:27:43FromDiscord<Yardanico> use distinct ints
12:27:47FromDiscord<Yardanico> what else do you want? :)
12:27:53FromDiscord<Clyybber> type Date = int
12:27:53narimiranyour attention.
12:27:55FromDiscord<ShalokShalom> Use them by default
12:28:01FromDiscord<Clyybber> type Money = int
12:28:05FromDiscord<Yardanico> we don't think that it's good to use them by default
12:28:06FromDiscord<ShalokShalom> Thats all
12:28:08narimiranuse them by default, who's stopping you? :D
12:28:09FromDiscord<Yardanico> that's all
12:28:19FromDiscord<Clyybber> @ShalokShalom No, you can't infer distinct types
12:28:20FromDiscord<ShalokShalom> @Yardanico And I did not asked, if you think it is a good idea
12:28:21PMunchBut how would Nim know which types to give them?
12:28:23mipriah it was Perl. Perl no longer allows any first index to arrays but zero.
12:28:23FromDiscord<ShalokShalom> I asked, how to do that.
12:28:26FromDiscord<Idefau> but tbh if you dont store dates in unix time why even make it just int
12:28:30miprihttps://perldoc.perl.org/5.30.0/perldelta#Assigning-non-zero-to-$%5B-is-fatal
12:28:33FromDiscord<Yardanico> @ShalokShalom you can't.
12:28:36FromDiscord<Yardanico> that's the answer
12:28:40FromDiscord<Yardanico> nim stdlib DOESN'T use them in most cases
12:28:44FromDiscord<Yardanico> it uses plain simple ints
12:28:44FromDiscord<Clyybber> @ShalokShalom In the end you still want each variable to have by default its own type
12:28:45FromDiscord<ShalokShalom> @PMunch Always the name, so birthday and account_balance in this case
12:28:54PMunchThen use the macro I sent you
12:28:55FromDiscord<Clyybber> No language does that, thats why you are viewed as trollish by some
12:29:01FromDiscord<ShalokShalom> @Yardanico Fine, that too quite a long time
12:29:09FromDiscord<Clyybber> Its still possible in Nim tho
12:29:15FromDiscord<ShalokShalom> @PMunch I will try, thanks
12:29:28narimiranshow us the example in F# where you can do those and they are different type without any extra annotations
12:29:40FromDiscord<ShalokShalom> @Clyybber No language did tons of things that are common in Nim.
12:29:46FromDiscord<ShalokShalom> That alone is no argument
12:29:57FromDiscord<Idefau> sent a code paste, see https://play.nim-lang.org/#ix=2Chz
12:29:58FromDiscord<Idefau> i am a genius
12:29:59FromDiscord<ShalokShalom> @narimiran I did not say, that F# can do that
12:30:01miprionce you get used to saying snowflakevar.int, snowflakevar.int all the time as you use these variables, you'll end up adding money to time anyway, after explicitly .int'ing them, and you'll get the same bug you would've got with unsafe primitive types. Your code will just be harder to read.
12:30:58FromDiscord<ShalokShalom> @Idefau This is interesting and it confused me a bit. Does this happen due to the PascalCase or how?
12:31:24miprithere's nothing special with the types in that code.
12:31:36FromDiscord<Idefau> wrong its a secret feature
12:31:53FromDiscord<ShalokShalom> @Clyybber But then I do have to specify every one of them. I want exactly that, just infered. :)
12:32:03FromDiscord<Clyybber> yes but it doesn't make sense
12:32:09FromDiscord<Clyybber> it gives each variable its own type
12:32:28FromDiscord<ShalokShalom> Yes, by default
12:32:31FromDiscord<ShalokShalom> I like that
12:32:32FromDiscord<Clyybber> read mipri's argument
12:32:38FromDiscord<Clyybber> as to why it doesn't make sense
12:32:39FromDiscord<ShalokShalom> I can still choose to use other types
12:32:44FromDiscord<Clyybber> or idf04's why it doesn't
12:32:51FromDiscord<Clyybber> @ShalokShalom well, you can do that in nim
12:32:56FromDiscord<Clyybber> with a macro
12:33:15FromDiscord<Clyybber> but you have to create that yourself, nobody is interested in this "feature" :P
12:33:34FromDiscord<ShalokShalom> @mipri And I did already ask half an hour ago, why I need to specify it like that and primitives apparently do not?
12:33:47Yardanicobecause "int" is just "int"
12:33:49Yardanicotwo ints are of same type
12:34:05Yardanicobut "type Money = distinct int" and "type Time = distinct int" are of different types
12:34:26FromDiscord<Clyybber> how do you add a type A and a type B
12:34:33FromDiscord<Clyybber> you convert them to int and add them
12:34:51FromDiscord<ShalokShalom> So, I fully accept that, but this reads to me like dynamic typing, to an extend.
12:35:04FromDiscord<Clyybber> its not
12:35:05FromDiscord<ShalokShalom> To use int all over the place, to make mixing easier
12:35:09FromDiscord<ShalokShalom> I know
12:35:14FromDiscord<Clyybber> like not at all
12:35:15FromDiscord<ShalokShalom> Its just the same motivation
12:35:18FromDiscord<Clyybber> no its not.
12:35:35FromDiscord<Clyybber> What you are proposing is mixing the type system into the symbolic system
12:35:47FromDiscord<Clyybber> which provides nothing but additional sophistication
12:35:51FromDiscord<ShalokShalom> @Clyybber https://play.nim-lang.org/#ix=2Chr
12:36:04FromDiscord<ShalokShalom> It got already created for me, thanks.
12:36:10FromDiscord<Clyybber> nice :D
12:36:38ForumUpdaterBotNew thread by JPLRouge: Help use mq posix , see https://forum.nim-lang.org/t/7001
12:37:15FromDiscord<ShalokShalom> @Clyybber Well, I accept that this is not good. But I don't see the difference between my idea and specifying distinctive types
12:37:27FromDiscord<ShalokShalom> Its just the default behavior that is turned upside down.
12:37:41FromDiscord<Clyybber> yes
12:37:49FromDiscord<ShalokShalom> So either I specify the types when I want them different or I do the opposite
12:38:02FromDiscord<ShalokShalom> And specify them, when I like them the same.
12:38:03FromDiscord<Clyybber> but this will never be an option because it doesn't make sense
12:38:08FromDiscord<Clyybber> feel free to use that macro tho
12:38:17FromDiscord<ShalokShalom> So I dont see, why I am such an evil person
12:38:23FromDiscord<Clyybber> nobody said that?
12:38:33FromDiscord<Idefau> i am eating banana
12:38:38FromDiscord<ShalokShalom> I got accused of trolling.
12:38:43FromDiscord<ShalokShalom> Two times.
12:39:05FromDiscord<Clyybber> people have opinions and different fuse lengths :)
12:39:27FromDiscord<Clyybber> your idea is very alien because it makes no sense to almost everyone :D
12:39:40FromDiscord<Clyybber> thats why its written off as trolling naturally
12:39:57FromDiscord<Clyybber> but hey, you got a solution now, go use it :)
12:40:14FromDiscord<ShalokShalom> So, I like to change this behavior and switch the default. And you mean that this makes no sense. Now, I assume you say that, because you mean that the current behavior favors, what is used more often, yes?
12:40:35FromDiscord<Clyybber> it favors what makes sense when coding
12:40:50FromDiscord<ShalokShalom> @Clyybber Trolling is something totally different and you all are very aware about that
12:40:52narimiranit favors real programmers, not trolls
12:41:00FromDiscord<Yardanico> @ShalokShalom not really
12:41:08FromDiscord<Clyybber> because types are not intended to be oneshots usually
12:41:08FromDiscord<Yardanico> you just haven't seen other trolls in this channel before :)
12:41:21FromDiscord<Clyybber> but with your default types are by default oneshots
12:41:27FromDiscord<haxscramper> @ShalokShalom try Idris and dependent type systems, might be interesting for you. Hypothetically
12:41:32FromDiscord<ShalokShalom> https://en.m.wikipedia.org/wiki/Internet_troll
12:41:36FromDiscord<Yardanico> yes
12:41:50PMunchTBH I kinda like his idea
12:41:50FromDiscord<Yardanico> "Application of the term troll is subjective."
12:41:51narimiranwhy do i have to manually have to type "troll", why it can't be inferred automatically?
12:42:16FromDiscord<ShalokShalom> @haxscramper Yeah, I thought about it. Scala 3 also has dependent types but I look for a language that has actively maintained bindings to Godot.
12:42:20FromDiscord<ShalokShalom> Thanks though
12:42:28miprion the one hand, the compiler should infer all trolls for me automatically, but on the other hand, every single variable should have its own incompatible type of troll and any conversion needs to be explicit
12:42:46FromDiscord<Yardanico> @ShalokShalom btw, do you know that your idea wouldn't make sense with Godot bindings?
12:42:57narimiran*anything
12:43:21FromDiscord<ShalokShalom> @Yardanico How you mean?
12:43:32FromDiscord<Yardanico> you'll have to do all the ".int" conversions again
12:43:38FromDiscord<Yardanico> because godot bindings aren't written in your style
12:43:44FromDiscord<Yardanico> they use normal primitive types
12:43:56FromDiscord<ShalokShalom> Yes, I understand that.
12:44:29FromDiscord<ShalokShalom> Does this change, when there is simple a type declaration over it?
12:44:40FromDiscord<ShalokShalom> As with the type keyword
12:44:42FromDiscord<Idefau> just cast everything when you are bored of its type
12:44:48FromDiscord<Idefau> thats what i do, keeps the code spicy
12:44:52narimiran:D
12:45:02FromDiscord<ShalokShalom> So far as I understand does that just overlay the actual type
12:45:23FromDiscord<Yardanico> yes, and makes it impossible to mix a distinct type with the base type without explicit conversions
12:45:52narimiranif only we could have a possibility to somehow write down some code and see if and how it works
12:46:03Yardanicowho needs to write code, we can just talk about it instead
12:46:23FromDiscord<Idefau> !eval echo cast[float64]("hello world")
12:46:25NimBot6.924719417612215e-310
12:46:30narimiransometimes even just talking has lots of bugs
12:46:31FromDiscord<Idefau> see, spicy
12:46:46PMunch-_-
12:47:14FromDiscord<ShalokShalom> @Yardanico But this counts only, when I specifically interact with the Godot API, so I can write the whole entire logic without conversions, so long as I dont interact with Godot code, yes?
12:47:25Yardanicoyes if you actually write code, then yes
12:47:36Yardanicobut maybe when you'll start using your idea in code you'll see why it's not always the best
12:47:52FromDiscord<lqdev> i wouldn't say you're a troll, you're just very vocal about your opinions :p
12:47:53Yardanico!eval import random; randomize(); let true = bool(random(0 .. 1)); echo true

12:48:10Yardaniconice
12:48:11FromDiscord<ShalokShalom> @narimiran Have this feeling since an hour
12:48:20FromDiscord<ShalokShalom> Thanks a lot you all.
12:48:24FromDiscord<Idefau> no problem
12:48:25FromDiscord<Idefau> anytime
12:49:01FromDiscord<haxscramper> @ShalokShalom what is your real-world use case? Not hypothetical musing about "40 distinct atrihnd", that might or might not be related to anything. What non-imaginary problem are you trying to solve? IDK, it might be useful to ask questions like that to yourself
12:49:13FromDiscord<ShalokShalom> @haxscramper There is no chance for such types in Nim, yes?
12:49:29Yardanicoyou. can. make. them. yourself
12:49:34Yardanicoin nim
12:49:40FromDiscord<haxscramper> There is work on "not nil", but they is different
12:49:44FromDiscord<Idefau> or just use the trick i told you
12:49:56FromDiscord<haxscramper> E.g. dataflow-dependent types
12:50:21FromDiscord<haxscramper> I don't exactly know correct term for this kind of thing, but it is more closely related to static analysis
12:50:33FromDiscord<ShalokShalom> @haxscramper I see the type system and its purpose served by it, its simply a disciple to prevent mixing types without intention to do so
12:50:36FromDiscord<haxscramper> Of data flow in code, not just types
12:50:42FromDiscord<ShalokShalom> Same cause for types in the first place
12:51:02mipria+b is intention to add a and b. a.int+b.int is also intention to add a and b.
12:51:36FromDiscord<ShalokShalom> @Idefau Oh, thanks for reminding me. I did ask, if this is requiring me to use capital letters, as you did?
12:51:40FromDiscord<Idefau> yes
12:51:41Yardanicomipri: but what if a doesn't like to be added!
12:51:45mipriby the code itself, neither the compiler nor a reader who doesn't understand more of the program can say whether the code aligns with some grander intention, like to not mix time and bank accounts
12:51:54YardanicoVariablesOpinionsMatter
12:52:12narimiranYardanico: `proc areYouWilling(a: a): aBool`
12:52:22FromDiscord<ShalokShalom> @Idefau Can you show me where this is described in the manual? Or how is it named, at least?
12:52:30FromDiscord<Idefau> its not described in the manual its a secret feature
12:52:35*mmohammadi9812 quit (Quit: Quit)
12:52:43miprithe ways to add this ability, to check intentions beyond whether your code merely type checks, are tests (famously) and theorem proving (developing)
12:52:48*mmohammadi9812 joined #nim
12:52:51FromDiscord<haxscramper> @ShalokShalom the question is just where "prevent mixing types" start to hinder productivity and for the sake of solving non-existent issues. Most languages don't have any kind of "distinct" types, except for wrapping everything in classes. Nim has distinct, but this is opt-in
12:53:20FromDiscord<haxscramper> But if you make it opt-out it just took annoying for 99% of the code
12:53:21FromDiscord<ShalokShalom> Yes, I just try to figure this out for myself
12:53:24miprialso, less automatically: documentation, comments, an easy to understand program layout
12:53:32FromDiscord<ShalokShalom> @haxscramper Ok, I understand
12:53:39FromDiscord<Clyybber> @ShalokShalom hes joking, its not a secret feature, you can use any capitalisation you want
12:53:50miprithere is no degree of type shit that you can pull that will make some variant of a+b "self checking".
12:53:51FromDiscord<ShalokShalom> @Clyybber Yeah, I guessed.
12:53:55FromDiscord<Clyybber> :D
12:53:58narimiran...but be sure to use something that nobody else uses
12:54:00FromDiscord<ShalokShalom> But then its not working the way he described it
12:54:44FromDiscord<Idefau> !eval const StringHello="Hello World"; echo StringHello.type
12:54:46NimBotstring
12:54:50FromDiscord<Idefau> see?
12:54:58FromDiscord<ShalokShalom> @mipri But could we not say the same about static types in general then?↡↡Could we not replace them with all those things?
12:55:01narimirantl;dr of last hour or so here: "can i do this?" "yes", "how?" "like this", "but i can't do it" "you can", "can you show me how?" "like this", "but i can't use it" "you can"
12:55:42FromDiscord<ShalokShalom> @haxscramper where is the difference between 'destinct' and 'type'?
12:55:47narimiranhttps://nim-lang.github.io/Nim/manual.html#types-distinct-type
12:55:56narimiraneven has examples!
12:55:58FromDiscord<Idefau> the difference is that `destinct` doesn't exist and `type` does
12:56:05miprisure yeah, you could all type checking and just have a NASA-tier spec. NASA put Forth into space after all.
12:56:36narimiranbut it has two currencies, not one currency and one birthday, so it must not be the thing asked for!
12:56:39mipriI'm not saying types aren't useful, just that you're wanting more from them than they can provide on their own.
12:56:42FromDiscord<ShalokShalom> @mipri I love domain modeling made functional, that is a technique that Scott Wlaschkin developmed and that uses pipes and option types, to do that.
12:56:50FromDiscord<ShalokShalom> Types in Nim are nominal, yeah?
12:56:55FromDiscord<ShalokShalom> Not structured?
12:57:00FromDiscord<Clyybber> theres concepts
12:57:04FromDiscord<Clyybber> but objects are nominal
12:57:23FromDiscord<ShalokShalom> Concepts?
12:57:27narimirannooooooooo
12:57:47FromDiscord<Idefau> the concept of a concept is well defined in the concept of a manual of a conceptual real world programming language
12:57:55FromDiscord<Clyybber> @ShalokShalom https://nim-lang.github.io/Nim/manual_experimental.html#concepts
12:58:07Yardaniconarimiran: :(((((((((((((9
12:58:07FromDiscord<ShalokShalom> @narimiran thanks a lot
12:58:44FromDiscord<lqdev> you know what? i'd just suggest that you stop complaining and asking about what nim is and just start programming in it.
12:59:02FromDiscord<lqdev> read the manual, understand language concepts
12:59:19FromDiscord<lqdev> and THEN share your opinions :)

13:03:45FromDiscord<ShalokShalom> I ask first, since it helps me to understand if I am interested to invest so many hours into it
13:05:25FromDiscord<haxscramper> I highly recommend
13:05:29FromDiscord<ShalokShalom> I think especially the type annotations everywhere make the otherwise very reasonable and readable syntax very confusing
13:05:31FromDiscord<haxscramper> ~manual
13:05:32disbot9manual: 11the Nim Manual is https://nim-lang.org/docs/manual.html
13:05:32disbot9manual: 11just good to Ctrl+F in cases like this -- 7haxscramper
13:05:41FromDiscord<haxscramper> Top to bottom, about 2-3 hours
13:05:44FromDiscord<ShalokShalom> I already looked through that multiple times.
13:06:06FromDiscord<ShalokShalom> And its well written, definitely the most helpful part of the documentation to me
13:07:04FromDiscord<haxscramper> Then, next question: what problem are you trying to solve with nim? Sometimes specific or just learning imperative programming in general?
13:07:38FromDiscord<haxscramper> If it the latter just do exercim or something, no amount of words can give good feeling for the language
13:07:44FromDiscord<haxscramper> Without writing code
13:08:21FromDiscord<ShalokShalom> Godot
13:10:21FromDiscord<Clyybber> btw godot uses variants a lot, essentially dynamic typing
13:12:37FromDiscord<ShalokShalom> @mipri I think this helps me a lot. Now I can see that I was constantly on the search to the mentioned domain modeling, that actually does that for me. So since pipes and option types are available in Nim, is this possible for me here. I am still annoyed by that type annotations πŸ˜‚
13:12:55FromDiscord<ShalokShalom> But it offers me so much more, like the macros and pure func.
13:13:03FromDiscord<ShalokShalom> Thats why I am annoying πŸ˜‹
13:14:13FromDiscord<ShalokShalom> @Clyybber Godot gets static typing truly in 4.0 and if you like it purely for the type checking (and not for the performance increase) is it already ready for that. It has also constants.
13:14:42FromDiscord<ShalokShalom> @Clyybber How you mean?
13:15:28FromDiscord<Clyybber> its C++/C api uses variants
13:15:37FromDiscord<ShalokShalom> Idk what that is.
13:15:49FromDiscord<Clyybber> I doubt they are gonna change that just because GDScript got static typing
13:15:55FromDiscord<ShalokShalom> Yes, yes
13:16:00FromDiscord<ShalokShalom> I misread that first.
13:16:06FromDiscord<ShalokShalom> Sorry
13:16:20FromDiscord<Clyybber> @ShalokShalom think of it as every object having an enum that indicates what it is
13:16:33FromDiscord<Clyybber> so if it is a Camera
13:16:36FromDiscord<Clyybber> or a Collider
13:16:54FromDiscord<Clyybber> and that information is not available at compile time

14:03:42blackbeard420when calling a nim library from c is simply calling 'NimMain' before the proc enough?
14:04:10PMunchIIRC that should be enough yeah
14:04:25blackbeard420thanks. it does work, i was just curious if i was missing anything
14:05:45PMunchAnd IIRC that is only required to initialise global variables
14:05:51PMunchAnd perhaps initialise the GC
14:06:44PMunchHmm, doesn't seem like it
14:07:07PMunchI don't call NimMain anywhere in my Nim DLL (or from the importing C code)
14:07:24PMunchOh wait, it might be run by some DLL hooks or something
