02:08:15FromDiscord<ripluke> How can I convert a float to an int
02:08:24FromDiscord<Elegantbeef> `int(myFloat)`
02:08:54FromDiscord<ripluke> Oh... Lol I tried parseInt but it only works for strings
02:09:20FromDiscord<Elegantbeef> Type conversions in Nim are done the above way
02:09:56FromDiscord<ripluke> Yea but strutils has a parseInt() and other functions
02:11:22FromDiscord<haskellandchill> that's not a type conversion
02:11:27FromDiscord<haskellandchill> it's parsing
02:13:36FromDiscord<haskellandchill> you are free to do `int("1")` but it's not gonna work
02:15:14FromDiscord<Elegantbeef> I mean you're free to try but that's a compile time error 😄
02:18:58*krux02 quit (Quit: Leaving)
02:34:32FromDiscord<Prestige> Elegantbeef: (possibly) a challenge - with the current mock, we can only substitute the calls at compile time, yes? Ideally for tests, we would change what the mocked function returns for each test. I've just started contemplating a solution, don't know if you have any thoughts on this
02:35:29FromDiscord<Elegantbeef> You cannot really
02:36:12FromDiscord<Prestige> Was thinking maybe a global variable that's generated by the macro, or maybe a table to lookup the caller and the return value
02:37:42FromDiscord<Elegantbeef> I guess you can inject a table access instead of a call
02:43:02*arkurious quit (Quit: Leaving)
02:49:13FromDiscord<Elegantbeef> You could also just use a function pointer of course
02:49:33FromDiscord<Prestige> Good point
03:11:43FromDiscord<Prestige> I still haven't figured out how to import this mocker file btw
03:12:04FromDiscord<Elegantbeef> You have to use the `--import:mocker` part of the compiler
03:14:40FromDiscord<Prestige> So I've added `--import:mocker` to my `config.nims` and I have `mocker.nim` in the `src` dir of my `nimtest` project (which is the testing suite library/binary)
03:16:41FromDiscord<Prestige> ah changed to `switch("import", "mocker")` but
03:17:09FromDiscord<Prestige> `Error: expression ' {.noRewrite.}: newStmtList([])' is of type 'NimNode' and has to be used (or discarded)`
03:17:26FromDiscord<Prestige> Getting this from one of the files from my nimtest library
03:17:50FromDiscord<Elegantbeef> Annotate the template with `: untyped`
03:18:07FromDiscord<Elegantbeef> the template didnt have a return value since it didnt need one when i was using it
03:20:12FromDiscord<Elegantbeef> But like i said buh bye compile times due to that pesky noRewrite not being respected
03:20:40FromDiscord<Prestige> Like this will increase compile times using it?
03:20:58FromDiscord<Elegantbeef> Yea
03:21:06FromDiscord<Prestige> Getting an error in my little test example for some reason, about using `..<` or `countup`
03:21:20FromDiscord<Elegantbeef> Someone broke the `{.noRewrite.}` pragma apparently
03:21:47FromDiscord<Prestige> aw dang
03:22:01FromDiscord<Elegantbeef> Oh perhaps i never worked
03:22:19FromDiscord<Elegantbeef> I just tested on the playground and it applies it recursively all the way back to 1.0
03:23:01FromDiscord<Prestige> 🤔
03:23:24FromDiscord<Prestige> How can I convert an int to a char equivalent
03:23:30FromDiscord<Prestige> like uh, 64 = a or whatever
03:24:44FromDiscord<Prestige> oh I got it
03:25:38FromDiscord<Prestige> https://play.nim-lang.org/#ix=40vk

04:53:07FromDiscord<Elegantbeef> Like yes opengl is just a giant state machine and it's just the worst, but it's also relatively easy to get anything done and has many features that are relatively easy to implement
04:53:18FromDiscord<Prestige> Hmm
04:53:50FromDiscord<Elegantbeef> Most of my code in truss3D is probably for GUI 😄
04:54:31*Amun-Ra joined #nim
04:56:05FromDiscord<Elegantbeef> My view is mostly that of indies and the like are better off spending their time with opengl as you actually can make a game instead of making a vulkan wrapper
04:57:34FromDiscord<Elegantbeef> But then again you arent making a game you're making tooling
04:57:37FromDiscord<Elegantbeef> So i guess you do you
05:14:37FromDiscord<Prestige> Any thoughts on the macro issue btw?
05:14:48FromDiscord<Elegantbeef> Cant say much without a repro
05:15:51FromDiscord<Prestige> I provided the code so you can repro

05:18:16FromDiscord<Prestige> mocker.nim I mean
05:18:18FromDiscord<Prestige> sure
05:18:39FromDiscord<Elegantbeef> I think i know the issue, but we'll see
05:18:49FromDiscord<Prestige> https://play.nim-lang.org/#ix=40vy
05:23:16FromDiscord<Elegantbeef> Hmmm this breaks iterator calls
05:24:00FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=40vz
05:24:22FromDiscord<Elegantbeef> Wait seems that just kills the matching
05:27:13FromDiscord<Elegantbeef> It shouldnt/doesnt match on an iterator so i dont get why it breaks it
05:28:10FromDiscord<Elegantbeef> Also you're really the worst
05:28:32FromDiscord<Elegantbeef> Nim has a ton of amazing features and you're using rand + 97 like it's C
05:28:38FromDiscord<Elegantbeef> `rand('a'..'z')`
05:30:28FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=40vC
05:35:29FromDiscord<Elegantbeef> Yep this mocker method fucking sucks
05:35:50FromDiscord<Elegantbeef> Use the module method i guess
05:36:49FromDiscord<Elegantbeef> then your `myProc(args)` just works
05:36:51FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=40vD
05:37:18FromDiscord<Elegantbeef> @Prestige\: there's a lot of rambling above for you 😛
05:37:21FromDiscord<Prestige> In reply to @Elegantbeef "`rand('a'..'z')`": had no idea I could do that lol
05:37:39FromDiscord<Elegantbeef> Works for all ordinals + floats
05:38:01FromDiscord<Elegantbeef> There's also `sample` for set/openarray
05:39:43FromDiscord<Prestige> That change above is working for you?
05:40:07FromDiscord<Elegantbeef> It did work, but it also broke with a minor change
05:40:14FromDiscord<Elegantbeef> Give up on this solution we're not using TRMs for what they're for
05:41:43FromDiscord<Rika> ~~TRMs are too powerful to use in any useful form tho~~
05:42:20FromDiscord<Elegantbeef> I really like what they can in theory enable you to do, they just are a bit broke apparently
05:43:06FromDiscord<Elegantbeef> The parameter matching syntax i do wish will stay for macros/templates
05:44:00FromDiscord<Elegantbeef> I dont think anyone's ever really used TRMs for anything that i know of, but i've used them a bit for toys like this
05:45:36FromDiscord<Prestige> D:
05:46:04FromDiscord<Elegantbeef> The module way is the way to go prestige 😄
05:46:10FromDiscord<Prestige> What do you mean?
05:46:36FromDiscord<Elegantbeef> The two modules that are imported/exported based off if a flag is passed
05:46:42FromDiscord<Prestige> ah..
05:46:44FromDiscord<Prestige> terrible
05:46:49FromDiscord<Elegantbeef> Eh it's not
05:46:55FromDiscord<Elegantbeef> It's better than this shit
05:47:09FromDiscord<Elegantbeef> It's atleast clear and uses sensible/reasonable mechanisms
05:47:26FromDiscord<Elegantbeef> It's as flexible as this without any overhead on the compiler side or your brain
05:49:03FromDiscord<Elegantbeef> You just have to make pointer procs for all procedures you want to mock, and could make a template handle it for you
05:50:43FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=40vE
05:51:12FromDiscord<Elegantbeef> Actually quite a nice API imho, but ymmv
05:52:03FromDiscord<Elegantbeef> mock is a bit of a shortcut cause `var doThing: typeof(doThing)` is a biiiit long
06:02:12FromDiscord<Prestige> lot more boilerplate for the user though, eh?
06:02:25FromDiscord<Elegantbeef> Mostly the same
06:03:24FromDiscord<Elegantbeef> You could make a macro that turned proc defs into pointer procs if `mock` is defined
06:03:55FromDiscord<Elegantbeef> Not as easy as the trm mess but it's more approachable
06:07:51FromDiscord<Prestige> hm well
06:08:02FromDiscord<Prestige> I'll need to think of a solution I guess
06:08:13FromDiscord<Prestige> I'm not sure what you have in mind tbh
06:08:26FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=40vK
06:09:18FromDiscord<Prestige> So would this need to be imported in all files and it'd add the mock pragma to everything?
06:09:35FromDiscord<Elegantbeef> what?
06:09:43FromDiscord<Elegantbeef> This works just like your normal proc macros
06:10:00FromDiscord<Elegantbeef> If you want to mock a procedure you add `{.mock.}` to it and it'll let you mock it
06:10:19FromDiscord<Elegantbeef> You could try to use a TRM to enable that mocking but i'll have no fun attempting to fight that macro
06:10:33FromDiscord<Prestige> Yeah so like
06:10:53FromDiscord<Prestige> if I have a proc that i need to mock, I'd need to add that pragma to it right?
06:10:58FromDiscord<Prestige> in the actual code, not the test
06:11:13FromDiscord<Elegantbeef> You can try a TRM to add `{.mock.}` to it
06:11:33FromDiscord<Elegantbeef> It's less aggressive than the other TRM
06:11:41FromDiscord<Prestige> true
06:11:48FromDiscord<Prestige> I suppose that's probably the best route...
06:12:03FromDiscord<Prestige> Is it non-trivial to add a pragma to a proc?
06:12:09FromDiscord<Prestige> with a TRM
06:12:17FromDiscord<Elegantbeef> It's just like adding it using a normal macro
06:12:29FromDiscord<Prestige> oh, alright good
06:12:42FromDiscord<Elegantbeef> Actually this is much simpler than i thought
06:15:50FromDiscord<Elegantbeef> Or... not `nkProcDef` isnt matched 😄
06:20:11FromDiscord<Prestige> hmm

08:31:02FromDiscord<Elegantbeef> Yea i cant say much
08:31:50FromDiscord<Phil> At least I know the error is almost definitely a runtime error caused by the way std/smtp interacts with the smtp server
08:32:14FromDiscord<Phil> Though where I use std/smtp wrong I don't know
08:32:16FromDiscord<Elegantbeef> "almost definitely a runtime error" is a funny read 😛

08:52:06FromDiscord<Phil> I'll throw this up on the forum as well and answer my own SO question (unless somebody answers it first) once I figured out what's wrong
08:53:36FromDiscord<xflywind> did you enable IMAP/SMTP serice in your email and get auth code?
08:53:49FromDiscord<xflywind> (edit) "did you enable IMAP/SMTP serice in your email ... and" added "settings"
08:53:56FromDiscord<Phil> I enabled SMTP, did not get an auth code though I was not aware there was one
08:54:24FromDiscord<Phil> Since the local mail providers page about that does not mention an auth code
08:54:45FromDiscord<Phil> Let me check if my python implementation needed such a thing
08:56:54FromDiscord<Phil> Hmm within my django app I didn't need to add some specific auth code of sorts (unless you mean login credentials for a user account, those I did have to provide but those I also try to provide in the nim examples, the server just never lets me get that far)
09:01:53PMunchMaybe have a look with Wireshark and see what the Python and Nim versions do differently?
09:03:24NimEventerNew thread by Isofruit: SMTP - 503 Bad sequence of commands with std/smtp, see https://forum.nim-lang.org/t/9251
09:04:17FromDiscord<Phil> Just to be on the safe side since I've got a suspicion, this is a problem with the mail provider, I take it others used this with googles smtp without issue?
09:05:19FromDiscord<xflywind> Yeah, I didn't use startTls though.
09:05:35FromDiscord<Phil> Hmmm I'll make a google dummy then
09:09:33FromDiscord<Phil> Yeeeeeh I'm pretty sure I'm doing something wrong on a more fundamental level, google is giving me the same responses
09:14:28FromDiscord<xflywind> Or `std/smtp` have regressions on stable.

09:16:20FromDiscord<enthus1ast> most smtp server these days want to see "ehlo" not "helo"
09:16:34FromDiscord<enthus1ast> you cannot just send helo you must check
09:16:44FromDiscord<enthus1ast> if the server understands esmtp
09:16:54FromDiscord<enthus1ast> then send ehlo
09:17:39FromDiscord<enthus1ast> eg the uni-frankfurt mailserver lets you connect with helo but all commands fail

14:17:31*PMunch quit (Quit: Leaving)
14:17:35FromDiscord<Phil> Or profiled nim code with the normal profiler
14:20:44FromDiscord<xflywind> In reply to @Isofruit "Or profiled nim code": Use valgrind on linux https://nim-lang.org/blog/2017/10/02/documenting-profiling-and-debugging-nim-code.html#profiling-with-valgrind
14:21:06FromDiscord<Phil> Errr alright
14:21:42FromDiscord<Phil> Just as a headsup, both hottie and the normal profiler did not properly record my stacktraces despite me having the correct flags enabled, so I might come back with questions about valgrind due to the same underlying issue in my using it or sth
14:22:52FromDiscord<xflywind> What is the normal profiler? nimprof?
14:23:38FromDiscord<Phil> Yeh
14:24:37FromDiscord<Phil> Added the flags as demanded there ("--profiler:on", "--stacktrace:on",) and my output I got was solely `total executions of each stack trace:`
14:24:40FromDiscord<xflywind> nimprof is hard to use for me.
14:24:43FromDiscord<Phil> (edit) "Added the flags as demanded there ("--profiler:on", "--stacktrace:on",) and my output I got was solely ... `total" added "the line"
14:25:16FromDiscord<xflywind> I used Intel VTune on windows.
14:25:23FromDiscord<arnetheduck> if you're looking for sampling profilers, `vtune` is hard to beat
14:26:07FromDiscord<Phil> Erm... assume I have not ever debugged memory before and am fine with something feature limited if it can be understood by an idiot?
14:26:52FromDiscord<Phil> Like, the extent of my profiling previously consisted of consulting snakeviz for python and look at its cake-diagrams regarding execution time
14:27:50FromDiscord<Phil> Mostly doing this since Rika asked for some profilings of my various pbkdf2 cryptography implementations that imitate the way python's Django does it
14:28:21FromDiscord<Phil> (edit) "Mostly doing this since Rika asked for some profilings of my ... various" added "(well "my" in quotation marks, hotdog wrote one and the first one was built with massive help from here as well)"
14:29:48FromDiscord<Phil> As for valgrind, I'll download that later, train Wifi is too slow to download 100mb
14:30:22FromDiscord<xflywind> I think you need to check the source code of nimcrypto. Profiler may not help too much in this situation.
14:31:01FromDiscord<Phil> I mean, I personally do not care too much, mostly wanted to follow a request to provide some profiling data
14:31:27FromDiscord<Phil> And I wanted to go over the version using nimcrypto, the one using openssl through python and the one using openssl directly

14:41:03FromDiscord<Phil> In reply to @ynfle "You can use benchy": This sounds like a much better suggestion than mine, do what this guy suggested Xzayler
14:41:20FromDiscord<Xzayler> In reply to @ynfle "You can use benchy": ok I guess I'll have to do some tests. I just asked in case there was some established "better" way to do it already
14:41:40FromDiscord<treeform> In reply to @ynfle "Has anyone done this": I am sure its not hard, just for x, for y loop the image and insert the colors into tesor?

14:42:16FromDiscord<ynfle> In reply to @treeform "I am sure its": Ok. I can give a pointer to the array, but it's or structs and I want to decompose the structucts.
14:42:25FromDiscord<treeform> In reply to @ynfle "<@107140179025735680> any idea?": Usually for ML you want to scale the image to some thing smaller first, like 64x64, and probably grayscale?
14:42:36FromDiscord<!Patitotective> In reply to @Xzayler "ok I guess I'll": im pretty sure the difference is subtle and you'll hardly notice
14:42:50FromDiscord<ynfle> It's not ML, it's traditional CV
14:42:51FromDiscord<Xzayler> In reply to @ynfle "What are you trying": nothing really, I just realised I'm using bools as "toggles" and often I have functions toggling the bool to one value when it's already that value and didn't know how wasteful it is compared to running an if check before toggling the value.
14:43:18FromDiscord<Phil> It's going to be comparatively negligible regardless of how you slice it I think
14:43:24reversem3[m]why doesn't the query work ?
14:43:34FromDiscord<ynfle> In reply to @Xzayler "nothing really, I just": Are really high performance?
14:43:36FromDiscord<Josef> How can I read & write into EAX register?
14:43:41FromDiscord<treeform> In reply to @ynfle "It's not ML, it's": Do you want to scale the image or grayscale it first?
14:43:53FromDiscord<ynfle> In reply to @treeform "Do you want to": grayscale, not scale
14:43:59FromDiscord<Xzayler> In reply to @ynfle "Are really high performance?": No, I'm just a beginner and paranoid. And my knowledge on what affects performance is close to 0
14:44:21FromDiscord<ynfle> In reply to @Xzayler "No, I'm just a": So probably don't worry about it
14:45:20FromDiscord<Phil> In reply to @Xzayler "No, I'm just a": You'll be fine, start worrying if you do something in a loop and what happens in that loop executes upwards of 5000 lines of code or works on some sort of string that is several megabytes long and you do that 1000 times or sth
14:46:36FromDiscord<Phil> Copying around large objects a lot or doing a lot of work in a loop/repeating work in a loop is more likely to be an issue than reassigning a boolean
14:46:55FromDiscord<Phil> (edit) "Copying around large objects a lot or doing a lot of work in a ... loop/repeating" added "massive"
14:50:08FromDiscord<Phil> There is such a thing as premature optimization and there's a quote flying around that it is the root of all evil. The essence is focus only on performance when you notice issues
14:51:25FromDiscord<treeform> In reply to @ynfle "grayscale, not scale": How do you create new tensor of width, height?
14:51:33FromDiscord<Phil> That can of course be taken to extremes, but the spirit is too not worry about the small things in terms of performance. Your algorithm in general is much more likely to heavily impact performance
14:52:00FromDiscord<treeform> found it!
14:53:47FromDiscord<treeform> nope, I can't figure our arraymancer docs

17:31:54FromDiscord<vindaar> you don't really expect any performance penalty using `nimpy` really compared to "native python'". It talks to a python interpreter straight via the CPython API↵(@Phil)
17:37:09FromDiscord<jmgomez> hey guys, question, how can I specify the size of an enum to be int32? It does work with byte but not with int32? Is there a way?
17:39:27FromDiscord<jmgomez> nvm uint32 works, which makes sense
17:43:47FromDiscord<jmgomez> hmm turns out you cant set the value if you assign a concrete size?
17:44:20FromDiscord<Phil> In reply to @vindaar "you don't really expect": Was more calling openssl via python vs calling openssl directly, I did expect some performance penalty there but I can barely make one out with benchy, and even that I'm not sure of how much it is just normal fluctuation
17:48:49FromDiscord<geekrelief> In reply to @jmgomez "hey guys, question, how": How are you specifying the size?
17:50:32FromDiscord<U9G> Hey, I'm just trying to cionvert python to nim, and I'm stuck on this:

17:51:23FromDiscord<Yardanico> you didn't `import std/tables`
17:51:32FromDiscord<U9G> at the top of my file I had `import os, httpclient, strformat, tables, strutils`
17:51:40FromDiscord<Yardanico> ah, right
17:51:42FromDiscord<Yardanico> `let itm`
17:51:48FromDiscord<Yardanico> then `itm` is immutable, but you want to change it
17:51:52FromDiscord<Yardanico> use `var itm` instead
17:52:09FromDiscord<Yardanico> also you don't have to call `initTable`, default initialized tables work just fine
17:52:44FromDiscord<U9G> thanks for the var tip
17:52:59FromDiscord<U9G> In reply to @Yardanico "also you don't have": so is `var itm = Intermediaries()` equivalent ?
17:53:03FromDiscord<Yardanico> yes
17:53:21FromDiscord<Yardanico> initTable docs say "Starting from Nim v0.20, tables are initialized by default and it is not necessary to call this function explicitly."
17:53:34FromDiscord<Yardanico> you only need to call initTable if you want to preallocate some non-default size to the table
17:53:45FromDiscord<Yardanico> to have less reallocations later, but that's just a minor optimization most of the time

17:57:31FromDiscord<geekrelief> In reply to @jmgomez "ohh, I saw somewhere": Not sure, where did you see code like that?
17:59:25FromDiscord<geekrelief> you could also specify the size by setting a Max value:

19:53:06FromDiscord<U9G> is there a difference between .nims and nims.cfg?

20:46:13FromDiscord<KatrinaKitten> How would one go about doing conditional compilation in Nim? I've received a request to adjust one of my libraries to use `jsre` instead of `re` when compiling for Javascript, but I'm not sure where to start.
20:46:35FromDiscord<Yardanico> `when`
20:46:39*oddish joined #nim
20:47:46FromDiscord<KatrinaKitten> That makes sense. What would I be looking for in the condition?

21:00:06FromDiscord<Elegantbeef> What are you wanting to do with `txt`
21:00:15FromDiscord<Elegantbeef> the easiest way is `lines("path").toSeq`
21:00:19FromDiscord<ynfle> What are trying accomplish with `stripLineEnd`
21:00:35FromDiscord<ynfle> (edit) "`stripLineEnd`" => "`stripLineEnd`?"
21:00:36FromDiscord<Elegantbeef> `toSeq` is in `std/sequtils`
21:01:11FromDiscord<U9G> In reply to @ynfle "What are trying accomplish": strip empty line so I dont have an empty string at the end of the array of line?
21:01:22FromDiscord<U9G> oh okay I’ll use lines
21:01:56FromDiscord<Elegantbeef> sent a code paste, see https://paste.rs/mOf
21:01:58FromDiscord<ynfle> In reply to @U9G "strip empty line so": You could just use strip
21:02:25FromDiscord<Elegantbeef> The above that i showed is how you use procs that expect `var T` with an immutable `T`
21:02:29FromDiscord<Elegantbeef> Not that it's the right solution here
21:03:43FromDiscord<Elegantbeef> Personally i'd ask "what are you doing with txt" anyway
21:12:45FromDiscord<haskellandchill> hm I wanna try dr nim
21:12:50FromDiscord<haskellandchill> is koch the best way?
21:13:07FromDiscord<Elegantbeef> No clue pretty much no one uses the profiler/dr nim
21:13:13FromDiscord<haskellandchill> yea figured
21:13:22FromDiscord<haskellandchill> I don't even have koch cause I used choosenim
21:13:41FromDiscord<Elegantbeef> Yea you need to build from source to get koch
21:13:55FromDiscord<Elegantbeef> And even then you dont really "get" it unless you desire it
21:14:00FromDiscord<haskellandchill> wah ok
21:14:12FromDiscord<haskellandchill> for science
21:14:21FromDiscord<Elegantbeef> Like i've never had koch in my path 😄
21:15:22FromDiscord<👾 br4n_d0n> What are the options I can use with ``when``?
21:15:30FromDiscord<Elegantbeef> Any compile time statement
21:15:43FromDiscord<👾 br4n_d0n> Is there a list somewhere?
21:15:54FromDiscord<Elegantbeef> No cause it's literally any compile time statement
21:15:57FromDiscord<ynfle> What's you question?
21:16:05FromDiscord<enthus1ast> when is the "compile time if"
21:17:16FromDiscord<enthus1ast> `when true:` `when 1 == 1:`
21:18:10FromDiscord<Elegantbeef> If you mean all the compiler defined defines there isnt a comprehensive list but generally it's just OS

21:35:33FromDiscord<👾 br4n_d0n> Hmm, can I alias a keyword?
21:35:56FromDiscord<Elegantbeef> Depends on what the keyword is
21:36:07FromDiscord<👾 br4n_d0n> bitwise or
21:36:13FromDiscord<Elegantbeef> That's not a keyword
21:36:28FromDiscord<Elegantbeef> that's an operator and Nim allows userdefined operators
21:37:14FromDiscord<👾 br4n_d0n> Sorry, I used the wrong term; I'm not great with them
21:41:45FromDiscord<KatrinaKitten> How do I check for a Javascript `null` from Nim? `== nil` gives me back type errors, `isNil` gives me "is an {.error.}", and I can't figure out what else to try
21:42:28FromDiscord<Elegantbeef> Is it a `ref object`?
21:43:23FromDiscord<KatrinaKitten> I don't think so, that's the issue; it's a `seq[cstring]`, but can be `null`
21:43:41FromDiscord<Elegantbeef> No it cannot be nil in nim land
21:43:54FromDiscord<Elegantbeef> you need to do `toJs(mySeq) != nil` probably
21:44:07FromDiscord<Elegantbeef> `seq[T]` is not nilable in Nim
21:45:31FromDiscord<KatrinaKitten> That worked, thank you!
21:46:31FromDiscord<Elegantbeef> Alternatively you can represent it as a `ref seq[T]` and it might give the semantics you want but i dont use the js backend much
21:47:13FromDiscord<KatrinaKitten> I don't need to use it extensively, just in a "patch" function that wraps `jsre` to be usable like `re` for my use cases, so `toJs` works fine here
21:47:40FromDiscord<Elegantbeef> Is there a reason you dont just use the pure Nim regex?
21:48:17FromDiscord<Elegantbeef> Though i'm sceptical about anyone using regex
21:48:20FromDiscord<KatrinaKitten> Normally I do, but I had a user request `jsre` support so I'm doing conditional compilation and patching in the functionality `jsre` doesn't support
21:48:36FromDiscord<KatrinaKitten> https://media.discordapp.net/attachments/371759389889003532/988561026683383818/unknown.png
21:48:46FromDiscord<Elegantbeef> `re` isnt pure Nim 😄
21:49:02FromDiscord<KatrinaKitten> Is there a pure Nim one?
21:49:13FromDiscord<ynfle> regex
21:49:14FromDiscord<Elegantbeef> https://github.com/nitely/nim-regex
21:49:14FromDiscord<Elegantbeef> yes
21:49:34FromDiscord<KatrinaKitten> Ah, yeah, I can't use that unfortunately. Part of the selling point of my library is that it has no third-party dependencies, it's stdlib only.
21:49:48FromDiscord<Elegantbeef> Except it has third party deps
21:49:51FromDiscord<ripluke> Can I have a function that returns void, but instead writes to the stdout
21:50:03FromDiscord<ynfle> re uses PCRE dll which is a third party dependency
21:50:10FromDiscord<Elegantbeef> `re` relies on PCRE
21:50:12FromDiscord<ynfle> In reply to @ripluke "Can I have a": Yes of coure
21:50:20FromDiscord<ripluke> Oh ok thx
21:50:34FromDiscord<ynfle> return void means not return any value
21:50:48FromDiscord<KatrinaKitten> In reply to @ynfle "re uses PCRE dll": I handwave that bit, because that's a third party dependency used by the stdlib itself.
21:50:53FromDiscord<Elegantbeef> You also dont need to annotate a procedure returns void
21:51:15FromDiscord<KatrinaKitten> (edit) "itself." => "itself, not one I'm adding on top of it."
21:51:15FromDiscord<ynfle> In reply to @KatrinaKitten "I handwave that bit,": Why no 3rd party deps?
21:51:45FromDiscord<Elegantbeef> Sure but it does have a third party dependancy and with a license attached to it
21:51:46FromDiscord<Elegantbeef> nim-regex is MIT licensed code
21:51:51FromDiscord<Elegantbeef> So you could if you really didnt want a third party dependency pull in nim-regex into your own repo and manage a fork that way
21:52:32FromDiscord<KatrinaKitten> It's admittedly a bit idiosyncratic on my part, but every dependency is a liability, so for a "tiny" library like this it doesn't make sense to depend on stuff the language doesn't already use in its "core" things.
21:52:53FromDiscord<Elegantbeef> I'd of course just say "use nim-regex through nimble" but if you really dislike third party deps the best thing is to have a fork in your project
21:53:10FromDiscord<Elegantbeef> This gives you the same API on every platform without issue
21:53:46FromDiscord<Elegantbeef> That makes no sense
21:54:03FromDiscord<Elegantbeef> Both carry the same risks
21:54:19FromDiscord<Elegantbeef> You're risking that the people ship the library with the code and also that the wrapping of it are proper
21:55:10FromDiscord<KatrinaKitten> In terms of same API, so does writing small extension functions to wrap `jsre` for the few `re` functions I use 🤷‍♀️ What really doesn't make sense at the moment, for a library I'm barely maintaining consistently anyway, to rewrite my entire library to not use `re` when I only need to wrap two functions of `jsre` and all my tests pass. If it becomes an issue in the future, I can always make the shift then.
21:55:19FromDiscord<KatrinaKitten> (edit) "In terms of same API, so does writing small extension functions to wrap `jsre` for the few `re` functions I use 🤷‍♀️ What really doesn't make sense at the moment, for a library I'm barely maintaining consistently anyway, ... to" added "is"
21:56:44FromDiscord<ripluke> What’s the equivalent to the python continue keyword in nim
21:56:55FromDiscord<huantian> `continue`
21:56:55FromDiscord<Elegantbeef> you arent going to believe this shit
21:56:58FromDiscord<Elegantbeef> It's `continue`
21:57:07FromDiscord<ripluke> Oh
21:57:18FromDiscord<ripluke> Ok that was a dumb question
21:57:27FromDiscord<d4rckh> In reply to @KatrinaKitten "": Wow nice font!
21:57:27FromDiscord<Elegantbeef> Continue
21:57:33FromDiscord<huantian> I can't believe nim would just shamelessly copy python like that tho

21:58:15FromDiscord<KatrinaKitten> I use it for readability, mostly
21:58:38FromDiscord<d4rckh> In reply to @KatrinaKitten "Ty, it's Comic Mono": Pretty sick
21:58:42FromDiscord<Elegantbeef> Damn i cannot type that should be "true"
21:58:46FromDiscord<d4rckh> I like Cascadia Code

22:13:15FromDiscord<ynfle> In reply to @br4n_d0n "and wanted to print": all (non float) number irrespective of how the are defined are integers and are binary in the computer's memory.

22:19:11FromDiscord<Elegantbeef> Yes you can seemlessly interop with a bitset of a given C size using this method without causing headaches
22:19:36FromDiscord<👾 br4n_d0n> Interesting
22:20:09FromDiscord<👾 br4n_d0n> What's the reason for using ``'u8`` at the end?
22:20:20FromDiscord<Elegantbeef> To make it a byte?
22:20:23FromDiscord<Elegantbeef> or a uint8 rather
22:20:37FromDiscord<👾 br4n_d0n> It cannot infer this?
22:20:45FromDiscord<Elegantbeef> Nim doesnt do backwards inference
22:20:57FromDiscord<Elegantbeef> the only inference it has is it's an integer with the first three bits set to x
22:20:59FromDiscord<ynfle> The default int type is int 64 or 32 depending on the machine
22:21:23FromDiscord<Elegantbeef> All unmarked literals are inferred to be the systems `int` type otherwise they're inferred of a callsite parameter
22:22:25FromDiscord<Elegantbeef> So where should it infer it's a uint8?
22:23:14FromDiscord<👾 br4n_d0n> 🤔 I feel dumb
22:23:24FromDiscord<Elegantbeef> ok
22:24:02FromDiscord<ripluke> Can I use nim script as a config language for my nim project?
22:24:08FromDiscord<Elegantbeef> You can
22:24:16FromDiscord<Elegantbeef> `config.nims` next to your binary
22:24:28FromDiscord<ripluke> Ohk
22:24:35FromDiscord<Elegantbeef> I mean not binary
22:24:45FromDiscord<Elegantbeef> source file or root directory of your project
22:25:16FromDiscord<ripluke> What if I want the config file in the config dir (~/.config)
22:25:34FromDiscord<Elegantbeef> You'd need to use load the nimscript
22:25:40FromDiscord<Elegantbeef> So this is where i mention nimscripter
22:25:45FromDiscord<ripluke> Ok
22:25:54FromDiscord<Elegantbeef> It's a library that makes nim \<-\> nimscript interop easy at runtime
22:26:09FromDiscord<ripluke> Ok I’ll check it out

22:29:00FromDiscord<👾 br4n_d0n> @ElegantBeef can Nim do a nibble? 😈
22:29:27FromDiscord<Elegantbeef> Is this a joke or do you have an elaborated question

22:31:00FromDiscord<Elegantbeef> So is there a serious question?
22:31:42FromDiscord<👾 br4n_d0n> Half serious half joke; my guess is unsigned inter of 8 bits is as low as the language goes
22:31:42FromDiscord<Elegantbeef> Do you want to know if nim can make a 4bit bitset?
22:32:11FromDiscord<Elegantbeef> I mean `0b010` is an integer literal
22:32:25FromDiscord<Elegantbeef> just cause you dont write all 64bits doesnt mean you dont want it to be 64bits
22:32:33FromDiscord<Elegantbeef> And that's why we have the type declaration
22:33:33FromDiscord<👾 br4n_d0n> ``0b1001'u4``
22:39:56FromDiscord<Elegantbeef> You cannot do that cause the smallest allocatable memory is 1 byte on modern computers
22:40:15FromDiscord<Elegantbeef> You can do something similar inside type defs
22:41:27FromDiscord<haskellandchill> building from source wish me luck

22:42:35FromDiscord<👾 br4n_d0n> In reply to @Elegantbeef "You cannot do that": What if you were running on some embedded platform that allowed this and you NEEDED to save the space?
22:42:57FromDiscord<Elegantbeef> embedded platforms dont generally allow lower allocations either
22:43:03FromDiscord<Elegantbeef> we're a 8 bit word world
22:43:14FromDiscord<Elegantbeef> Does exist though
22:43:15FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=40z0
22:44:12FromDiscord<Elegantbeef> for a u4 you'd do `myField {.bitSize: 4.}: 0u8..15u8`
22:44:37FromDiscord<Elegantbeef> Then you'd only be allowed to use 0..15
22:45:12FromDiscord<👾 br4n_d0n> Lol, so you're setting a range, but does that actually equate to a smaller size?
22:45:24FromDiscord<Elegantbeef> the `bitsize` is the important part
22:45:29FromDiscord<Elegantbeef> it forces it to be 4 bits
22:46:45FromDiscord<Elegantbeef> But if you only have a single field that's 4 bits the system is still going to allocate 8 cause it cannot allocate fewer
22:46:51FromDiscord<Elegantbeef> Like i said welcome to 8bit words
22:47:13FromDiscord<👾 br4n_d0n> Yeah, but you can have 2 nibbles then
22:48:05FromDiscord<exelotl> lol I've been packing bits today a lot :p
22:48:14FromDiscord<haskellandchill> lots of warnings but appears to have worked
