00:03:38FromDiscord<Elegantbeef> you can `export sqlite` if you need
00:03:38FromDiscord<Elegantbeef> What's the error without the import?
00:05:19FromDiscord<Isofruit> sent a long message, see http://ix.io/3Kts
00:05:49FromDiscord<Isofruit> At least I assume it#s trying to use std/sqlite3
00:06:12FromDiscord<Isofruit> (edit) "std/sqlite3" => "std/db_sqlite3"

00:06:33FromDiscord<Isofruit> (edit) "http://ix.io/3Ktv" => "https://paste.rs/clh"
00:07:45FromDiscord<Elegantbeef> `selectAll` is a generic aswell, so `bind select`
00:07:46FromDiscord<Isofruit> Actually, that first definition of select might be from norm/sqlite.... but then it should also recognize that dbConn is of type `DbConn` since norm/sqlite has a `using` statement inside of itself

00:10:16FromDiscord<Isofruit> (edit) "https://play.nim-lang.org/#ix=3Kty" => "https://play.nim-lang.org/#ix=3Ktz"
00:10:37FromDiscord<Elegantbeef> What about with `bind select`?
00:10:53FromDiscord<Elegantbeef> I'm guessing no change
00:11:18FromDiscord<Isofruit> sent a long message, see http://ix.io/3KtA
00:11:58FromDiscord<Elegantbeef> Hmmm
00:12:25FromDiscord<Elegantbeef> Might be best to just add the `export sqlite` though i dont know
00:13:17FromDiscord<Isofruit> I'd love for `genericArticleRepository.nim` to provide the functions from norm/sqlite so that in all the other `.nim` files that will import that module, I'll no longe rhave to manually import `norm/sqlite`
00:13:41FromDiscord<Elegantbeef> I just told you to do that
00:13:59FromDiscord<Elegantbeef> You can export modules from modules
00:14:02FromDiscord<Isofruit> ... I really do notice it's 1 am once more
00:14:16FromDiscord<Isofruit> okay, let me read up a bit on export first, then I'll try that one
00:14:30FromDiscord<Elegantbeef> if you just do `export sqlite` in your one module it'll export all symbols from `sqlite` to other modules
00:17:00FromDiscord<Isofruit> Alright, and I can do export sqlite instead of export norm/sqlite because my import norm/[sqlite, model] statement has already brought "sqlite" into my scope, so I already have the module flying around and can thus just grab it by the name and export it
00:17:13FromDiscord<Elegantbeef> Correct!
00:17:29FromDiscord<Isofruit> (edit) "export sqlite" => "`export sqlite`" | "export norm/sqlite" => "`export norm/sqlite`" | "import" => "`import" | "model]" => "model]`"
00:18:15FromDiscord<Isofruit> Man, this feels like learning async coding again / learning how to use rxjs, head swirls a bit but slowly the individual bobs make sense
00:18:37FromDiscord<Isofruit> Thank you so much for the advice!
00:19:04FromDiscord<Elegantbeef> No problem
00:23:13FromDiscord<Isofruit> I wonder if writing C is like this, but with extra memory chaos on top
00:23:32FromDiscord<Elegantbeef> Nah C is simpler, no generics, no modules, no overloads
00:23:40FromDiscord<Elegantbeef> forgot the last no, which is no fun
00:24:25FromDiscord<Isofruit> .... overloads is the one thing that allows me to make the entire fetching of DB stuff through norm generic, I shudder to think if that weren't a thing
00:24:35FromDiscord<Isofruit> And the "no modules" thing seems like utter murder
00:24:43FromDiscord<Elegantbeef> you'd manually overload doing `doSomething_MyType`
00:25:25FromDiscord<Elegantbeef> I mean that's just how C is
00:25:40FromDiscord<Elegantbeef> Zig adds a few niceties ontop of what C has but is also still pretty primitive
00:27:34FromDiscord<Elegantbeef> random language facts no one asked for
00:29:49FromDiscord<Isofruit> It's nice to see, I've really not spent much time in languages that go this deep, I've made a living off of python, JS/TS, Groovy and Java so far, so getting to know more in that space is really interesting
00:30:21FromDiscord<Isofruit> I've, e.g. heard D so far only by name, really no idea what's behind it other than that it's also low level. I likely could look at it to get a deeper idea, but I've got my hands full with nim atm either wy
00:30:23FromDiscord<Isofruit> (edit) "wy" => "way"
00:47:32FromDiscord<Isofruit> Huh, decorating a piece of code with try catch through a template works pretty easily, nice
01:01:59FromDiscord<kaddkaka> sent a code paste, see https://play.nim-lang.org/#ix=3Ku2
01:02:46FromDiscord<kaddkaka> `for n in numbers:` yields immuatables
01:02:54FromDiscord<Elegantbeef> `.mitems`
01:04:36FromDiscord<kaddkaka> right, also, why does `pairs` seem to be optional? Is there a difference between `for i, n in pairs numbers:` and `for i, n in numbers:`?
01:04:49FromDiscord<Elegantbeef> `x, y` implicitly calls `pairs`
01:04:54FromDiscord<Elegantbeef> `x` calls `items`
01:16:21FromDiscord<kaddkaka> how does nim select between tuple unpacking and implicitly calling pairs? Is it noy possible to get implicit `pairs` for a sequence like `var numbers = @[(1, 2), (5, 7), (15, 18)]`?
01:16:28FromDiscord<kaddkaka> (edit) "noy" => "not"
01:16:43FromDiscord<Elegantbeef> `for (x, y) in numbers` if you want to unpack them
01:16:50FromDiscord<Elegantbeef> otherwise you'll get `index, tuple`
01:19:32FromDiscord<kaddkaka> oh right, not if I ust `mitems` though, then I can unpack without parentheses
01:19:37FromDiscord<kaddkaka> (edit) "ust" => "use"

01:20:56FromDiscord<kaddkaka> which seems surprising to me
01:21:44FromDiscord<Elegantbeef> The above works or doesnt?
01:21:49FromDiscord<kaddkaka> it works
01:22:10FromDiscord<kaddkaka> sent a code paste, see https://play.nim-lang.org/#ix=3Kud
01:22:23FromDiscord<Elegantbeef> Didnt expect it
01:22:24FromDiscord<Elegantbeef> Interesting
01:25:04FromDiscord<kaddkaka> sent a code paste, see https://play.nim-lang.org/#ix=3Kuf
01:25:30FromDiscord<Elegantbeef> Should be a proper error but it's not safe
01:25:54FromDiscord<kaddkaka> which is also strange, maybe? I'm too new Nimmer to know if I'm doing stupid stuff ^^'
01:26:19FromDiscord<kaddkaka> whats wrong/incorrect in the above snippet?
01:27:51FromDiscord<Elegantbeef> `mitems` yields `var (int, int)`
01:28:30FromDiscord<Elegantbeef> You cannot presently get what you want
01:29:33FromDiscord<ajusa> how do I parse an ISO8601 date? `"yyyy-MM-dd'T'HH:mm:ss'.'ffffff'Z'"`?
01:32:25FromDiscord<Elegantbeef> The issue is you'd need something to yield `(int, var int)`
01:32:38FromDiscord<Elegantbeef> sorry `(int, var (int, int))`
01:32:57FromDiscord<kaddkaka> In reply to @Elegantbeef "You cannot presently get": Hmm, ok, so no way to chain/combine mitems and pairs?
01:32:59FromDiscord<Elegantbeef> Which is not possible without `views`
01:33:30FromDiscord<kaddkaka> ok, I saw that being mentioned here before, is that a new language construct being worked on?
01:34:03FromDiscord<Elegantbeef> Yes presently it's experimental
01:34:45FromDiscord<kaddkaka> I would have expected `numbers.mitems.pairs` to maybe work, but pairs does accept an iterable I think (`expression 'mitems(numbers)' is of type: iterable[var (int, int)]`)
01:35:05FromDiscord<Elegantbeef> Checkout `std/enumerat`
01:35:15FromDiscord<Elegantbeef> `std/enumerate`
01:36:35FromDiscord<kaddkaka> (edit) "does" => "doesn't"
01:39:37FromDiscord<kaddkaka> Why does enumerate require `std/` ( `import std/enumerate`) while for example `import sequtils` works?
01:41:09FromDiscord<Elegantbeef> Legacy support, all stdlib should require `std` but for legacy support they dont
01:42:46FromDiscord<kaddkaka> ok
01:48:06FromDiscord<ajusa> In reply to @ajusa "how do I parse": oh god chrono doesn't support fractional timestamps in ISO8601, this is painful
01:48:57FromDiscord<kaddkaka> Looking at `enumerate`: I guess macros don't follow UFCS?
01:49:32FromDiscord<Elegantbeef> It's a for loop macro so no it does not
01:52:48FromDiscord<kaddkaka> Does that mean that other kinds of macros can support UFCS?
01:52:57FromDiscord<Elegantbeef> Yes

03:58:50FromDiscord<creikey> sent a code paste, see https://play.nim-lang.org/#ix=3Kv7
03:58:56FromDiscord<creikey> why does parallel think that `spawn findWinLosses` is discarded?
04:01:48FromDiscord<Rika> Can you put this in a paste? I can’t read it because of the indent level
04:03:00FromDiscord<Rika> Ah I don’t see a problem here though I don’t use spawn often
04:03:32FromDiscord<Elegantbeef> I have a hypothesis so let's see 😀
04:04:21FromDiscord<Elegantbeef> It might be the assignment to a variable through `[]=`
04:04:35FromDiscord<creikey> I see parallel requires that it's an array/sequence indexed by integers
04:04:35FromDiscord<Rika> Yeah that’s one guess
04:05:02FromDiscord<creikey> I refactored it to be like that but parallel froze (some kind of race condition?) so I'm changing it to be spawn since parallel is experimental
04:16:18FromDiscord<creikey> sent a code paste, see https://play.nim-lang.org/#ix=3Kvt
04:16:22FromDiscord<creikey> how do I make it execute at the same time
04:16:31FromDiscord<Elegantbeef> `^` is blocking
04:16:40FromDiscord<creikey> right but while it's blocking for that shouldn't the other threads be executing?
04:16:46FromDiscord<creikey> or am I missing somethign
04:16:48FromDiscord<creikey> (edit) "somethign" => "something"
04:17:01FromDiscord<Elegantbeef> put a `sync()` after the first for loop
04:17:51FromDiscord<Elegantbeef> I havent used `spawn` or `parallel` so i'm just going off the examples and what i read
04:17:53FromDiscord<creikey> In reply to @Elegantbeef "put a `sync()` after": still happening one by one
04:18:18FromDiscord<creikey> the process is consuming 43% of 4 core 8 thread cpu and a lot of memory https://media.discordapp.net/attachments/371759389889003532/927053161317928980/unknown.png
04:18:27FromDiscord<creikey> memory might just be other stuff in the program though
04:18:37FromDiscord<creikey> well I mean it shouldn't be that much I dunno
04:18:46FromDiscord<creikey> maybe it's the garbage collector for each thread
04:18:49FromDiscord<Elegantbeef> References are deeply copied
04:18:50FromDiscord<creikey> of which 157 were spawned
04:19:00FromDiscord<creikey> In reply to @Elegantbeef "References are deeply copied": `findWinLosses(champ1: string, champ2: string, games: seq[Game])
04:19:01FromDiscord<creikey> (edit) "seq[Game])" => "seq[Game])`"
04:19:02FromDiscord<creikey> no refs
04:19:03FromDiscord<Elegantbeef> you can do `--gc:orc` after if that's concerning
04:19:16FromDiscord<creikey> seq isn't copied right
04:19:18FromDiscord<creikey> it's only read
04:19:19FromDiscord<creikey> (edit) "it's only read ... " added "from"
04:19:31FromDiscord<Elegantbeef> It hopefully isnt but idk
04:20:50FromDiscord<creikey> I guess I'll try a release build?
04:20:54FromDiscord<creikey> no idea what's going on
04:21:02FromDiscord<creikey> release build seems like multiple things are happening at once maybe
04:21:04FromDiscord<creikey> yeah
04:21:10FromDiscord<creikey> but it's only like two things
04:21:27FromDiscord<creikey> have to say not impressed with nim's thread pool so far
04:21:56FromDiscord<creikey> I'm definitely doing something wrong though
04:22:06FromDiscord<Yardanico> In reply to @creikey "have to say not": threadpool is kind of abandoned, so yes
04:22:16FromDiscord<creikey> In reply to @Yardanico "threadpool is kind of": only use `parallel:` or what?
04:22:26FromDiscord<Yardanico> parallel is a part of threadpool too and it's kind of abandoned as well :)
04:22:38FromDiscord<creikey> what is the new way of doing parallelism in nim that they've abandoned into
04:22:51FromDiscord<Yardanico> well you can always use the traditional threads way
04:23:19FromDiscord<Yardanico> current new things are arc/orc and they have shared heap, destructors, move semantics and other things, so threading is kind of reworked for them
04:23:22FromDiscord<Yardanico> e.g. https://github.com/nim-lang/threading
04:23:35FromDiscord<creikey> In reply to @Yardanico "current new things are": arc is that super performant gc right
04:24:06FromDiscord<Yardanico> https://nim-lang.org/blog/2020/10/15/introduction-to-arc-orc-in-nim.html and https://nim-lang.org/blog/2020/12/08/introducing-orc.html
04:24:15FromDiscord<Yardanico> and https://nim-lang.org/docs/destructors.html :)
04:24:32FromDiscord<creikey> wow a year ago and things still aren't stable?
04:24:50FromDiscord<Yardanico> well they are not 100% compatible with refc
04:25:09FromDiscord<Yardanico> orc is supposed to become default in 2.0 which will probably be the next release after 1.6, but I don't know for sure
04:26:39FromDiscord<Yardanico> but for most stuff ORC is already perfectly usable
04:30:09FromDiscord<Yardanico> also there's weave https://github.com/mratsim/weave, but seems like Status is making another lib which has some code from it (and mratsim seems like the one developing it mainly) - https://github.com/status-im/nim-taskpools
04:30:19FromDiscord<Yardanico> taskpools seems like it's pretty early in development though
04:30:41FromDiscord<creikey> weave is a work of art but idk if I want to add a nimble dependency

04:45:21FromDiscord<creikey> can nim thread procs take var arguments?
04:45:50FromDiscord<Elegantbeef> Nope
04:46:42FromDiscord<Elegantbeef> You'd need to pass a `ptr`
04:46:46FromDiscord<creikey> In reply to @Elegantbeef "Nope": so how can I get data from a thread
04:46:50FromDiscord<creikey> In reply to @Elegantbeef "You'd need to pass": I see
04:47:09FromDiscord<creikey> In reply to @Elegantbeef "You'd need to pass": I remember reading this somewhere on the threadpool docs but thought it was just for those not all threads
04:47:17FromDiscord<creikey> https://nim-lang.org/docs/threads.html this says nothinga bout that
04:47:19FromDiscord<creikey> (edit) "nothinga bout" => "nothing about"
04:47:50FromDiscord<Elegantbeef> Well `var T` isnt type valid outside of iterators and parameters
04:47:58FromDiscord<Elegantbeef> So `Thread[var int]` isnt valid
04:48:15FromDiscord<Elegantbeef> Dont know if it will be eventuall
04:49:42FromDiscord<Yardanico> In reply to @creikey "so how can I": channels or global variables + locks (with arc/orc)
04:49:52FromDiscord<creikey> ah yeah forgot about channels
04:49:53FromDiscord<Yardanico> also ptrs too but you need locks anyway
04:50:09FromDiscord<creikey> for ptrs you wouldn't need a lock if it's setting separate memory right?
04:50:30FromDiscord<Yardanico> if each thread gets separate memory location, then sure

I have a database containing hashed passwords among other things and I'm in the process of re-building my backend from using python (Django) to using nim (Prologue).↵Now what that also means is that I need to re-build for login purposes how I hash incoming passwords into hashes and compare them with what I have in my database
15:10:36FromDiscord<Isofruit> (edit) "I hash" => "Django hashes"
15:17:20FromDiscord<Isofruit> sent a long message, see http://ix.io/3KCT
15:20:12FromDiscord<enthus1ast> salt is usually concatinated to the input, eiter in front or back, for details i would read the django source
15:20:16PMunchSalt is basically just a little piece of random data appended or prepended to you password to make sure that the same password won't be hashed to the same thing
15:20:31PMunchSo probably just try to add in on either end and run the hashing
15:22:11FromDiscord<planetis> how do i tell nim to search for dynamic library in the same directory as the executable?
15:22:18FromDiscord<Yardanico> that's OS-specific
15:22:24FromDiscord<Yardanico> on linux use LD_LIBRARY_PATH
15:22:27PMunchLD_LIBRARY_PATH=.
15:22:35FromDiscord<planetis> thank you
15:28:24FromDiscord<Isofruit> Thanks (to you as well PMunch)! Yeh I only knew that I needed a salt, not how exactly that was calculated in there. Thanks! I'll check out the source code
15:28:49FromDiscord<Isofruit> (edit) "Thanks (to you as well PMunch)!" => "Thanks!"

15:29:03*neurocyte4 joined #nim
15:29:17FromDiscord<Yardanico> In reply to @Isofruit "Thanks! Yeh I only": the main point of using the salt is that even if someone gets access to the hashes, they can't use existing rainbow tables to bruteforce them
15:29:50FromDiscord<Isofruit> Ohhh I had been wandering about that
15:29:55FromDiscord<Yardanico> and they can't really make a new rainbow table since each password has a different salt
15:29:58FromDiscord<Isofruit> (edit) "wandering" => "wondering"
15:30:07FromDiscord<Yardanico> so they have to do bruteforce the slower way
15:30:42FromDiscord<Isofruit> On the one hand, having to re-implement a lot of the stuff Django used to do for me is annoying.↵On the other, it's also pretty educational
15:32:19PMunchI thought Prologue had some login middleware already?
15:33:06FromDiscord<Isofruit> It has a basic auth middleware, I use JWTs↵So I glanced over that middleware and didn't really see anything in there that jumped out to my not-all-that-hashing-wise-trained eye
15:33:15PMunchBut I guess it wouldn't be compatible to Djangos system..
15:33:55FromDiscord<enthus1ast> build it yourself and make pr to Prologues repo \:)
15:34:35FromDiscord<Isofruit> I'll build something alright.↵And then try to generalize it out
15:34:51FromDiscord<Isofruit> Damn, I do not consider myself competent enough to do this, but you gotta be the change you want to see in the world.
15:37:45FromDiscord<Isofruit> Wait a minute
15:38:18FromDiscord<Isofruit> If my Django hashes can contain +, / and = signs, that means they are not just hexadecimal
15:39:10FromDiscord<Isofruit> ... Yeah, I'm seeing the entire alphanumerical space + extra signs in there, wth is that encoded in
15:44:08FromDiscord<Isofruit> Does anyone have a different library or understands how to parse whatever they're computing into a string?
15:44:16FromDiscord<Yardanico> In reply to @Isofruit "... Yeah, I'm seeing": base64
15:44:23FromDiscord<Yardanico> https://nim-lang.org/docs/base64.html
15:45:18FromDiscord<Isofruit> Ah, fair, my brain was so settled on hex since the SHA256 lib offers a function for that
15:46:27FromDiscord<Isofruit> But yeah, this is what that library outputs, not sure what's going wrong there other than that the letter encoding doesn't seem to be working well https://media.discordapp.net/attachments/371759389889003532/927226340409749534/Screenshot_from_2022-01-02_16-45-20.png
15:47:03FromDiscord<Yardanico> you're trying to print binary data
15:47:06FromDiscord<enthus1ast> these are the plain bytes outputted to the terminal
15:47:18FromDiscord<Yardanico> that's why base64 is used in cases like this
15:47:25FromDiscord<Yardanico> to encode this binary data in printable ASCII characters
15:47:55FromDiscord<Isofruit> OH IT OUTPUTS the raw binaries... as string?
15:48:13FromDiscord<Yardanico> raw bytes, yes
15:48:19FromDiscord<Yardanico> it's a hash after all
15:48:32FromDiscord<Yardanico> the typical sha256 representation that you see is actually a hex representation of the bytes
15:49:30FromDiscord<Isofruit> Hmmmm
15:50:42FromDiscord<enthus1ast> and you should also do the repetitions on the binary data, then when you're done output as base64 and store in database
15:51:15PMunchHow do I write a format for times.parse to handle a string like this: 2022-01-03T06:00:00.000+0000
15:51:46FromDiscord<enthus1ast> is this iso date?
15:51:49PMunchI tried yyyy-MM-ddTHH:mm:ss.fff+zzzz but it complains that Error: unhandled exception: 'T' is not a valid pattern [TimeFormatParseError]
15:52:08FromDiscord<enthus1ast> extra chars must be escaped
15:52:11FromDiscord<Yardanico> In reply to @PMunch "I tried yyyy-MM-ddTHH:mm:ss.fff+zzzz but": you need to escape T
15:52:25FromDiscord<Yardanico> > Other strings can be inserted by putting them in ''
15:52:27FromDiscord<Yardanico> so 'T'
15:52:34PMunchI tried to escape the T, then it said that ' ' was not a format
15:53:05FromDiscord<enthus1ast> https://github.com/nim-lang/Nim/blob/afa4bc34b41307c6c63e8c7c973afe295e9fedd8/lib/pure/times.nim#L2168
15:53:33PMunchWhy the T and not the - and :?
15:53:54FromDiscord<Yardanico> "The following characters can be inserted without quoting them: : - ( ) / [ ] ,"
15:53:56FromDiscord<Yardanico> :P
15:55:58FromDiscord<Yardanico> also you should use ZZZ instead of zzzz without inserting + yourself
15:56:03FromDiscord<Yardanico> let dt = parse("2022-01-03T06:00:00.000+0000", "yyyy-MM-dd'T'HH:mm:ss'.'fffZZZ")
15:59:21FromDiscord<Isofruit> Hmmm
15:59:36FromDiscord<Isofruit> well, I'm getting a decent hash as output at least, which is really good!
16:00:10FromDiscord<Isofruit> I'm just not getting the correct hash =/↵I'll need to take a look at the django source again
16:00:21FromDiscord<Isofruit> `encode($computeSHA256(plainpw&salt, 180000))`↵That at least get's me where I want to go
16:00:29FromDiscord<Yardanico> do you require using 100% same hash as django ?
16:00:30FromDiscord<Yardanico> any reason why?
16:01:14FromDiscord<Yardanico> also obviously you will never get the same hash if you use random salts
16:01:16FromDiscord<Isofruit> Well, my current db is hosted via Django
16:01:32FromDiscord<Yardanico> oh you want to use an existing db
16:01:35FromDiscord<Isofruit> I effectively have around 20 entries that I need to be able to "recreate"
16:01:56FromDiscord<Isofruit> My usebase is like 6 people so that works out for me
16:03:09FromDiscord<Yardanico> also django is sha256 + PBKDF2
16:03:11FromDiscord<Yardanico> not just sha256
16:04:00FromDiscord<Isofruit> Wait that's a difference?
16:04:03FromDiscord<Yardanico> yes
16:04:06FromDiscord<Yardanico> https://github.com/cheatfate/nimcrypto can do both sha256 and pbkdf2
16:04:06FromDiscord<Isofruit> Dangit
16:04:31*kenran joined #nim
16:05:37FromDiscord<Isofruit> huh
16:05:38FromDiscord<Isofruit> er
16:05:58FromDiscord<Isofruit> I guess I'll brute force which combination of sha256, pbkdf2 and 18000 repetitions gives me my hashes ?
16:06:12FromDiscord<Isofruit> or get the django implementation, anyway
16:06:23FromDiscord<Isofruit> (edit) "or get ... the" added "a look at"
16:07:13PMunchWell that's just super confusing :P
16:09:09FromDiscord<enthus1ast> django can use multiple algos not just pbkdf2
16:09:10FromDiscord<enthus1ast> https://github.com/django/django/blob/b0d16d0129b7cc5978a8d55d2331a34cb369e6c7/django/contrib/auth/hashers.py
16:09:18FromDiscord<enthus1ast> also argon2
16:09:23FromDiscord<Yardanico> yes but pbkdf2 is the default
16:09:45FromDiscord<Isofruit> I Just double checked my settings.py file, I have not changed the default, it's pbkdf2
16:09:56FromDiscord<Isofruit> With sha 256
16:10:20PMunchHmm, I wish there was a compare thing in times that could ignore parts of the DateTime..
16:10:29PMunchI guess I could just zero out those parts
16:10:54FromDiscord<Isofruit> Hm? You mean for parsing in?
16:10:57FromDiscord<Isofruit> Or for what?

17:23:45FromDiscord<treeform> In reply to @soundmodel "so I wonder if": Nimble can be very strange, I recommend to uninstall and reinstall what you need if stuff does not work or does not update.
17:25:09FromDiscord<treeform> In reply to @soundmodel "I also don't understand": Yeah that's just how templates work.

19:00:26FromDiscord<kaddkaka> In reply to @Solitude "https://nim-lang.org/docs/sequtils.html#allIt.t%2Cu": ah so there was an option! Perhaps surprising that it uses `it` and not `a`.
19:01:00FromDiscord<Solitude> look at other thingIt templates
19:01:45FromDiscord<kaddkaka> I understand and guessed that it matches other `It` templates. But why is `foldl ` the odd one out

19:15:05FromDiscord<Rosen> In reply to @Shiba "I don't understand why": what is `points`
19:15:23FromDiscord<kaddkaka> And skip the identity procedure `(a) => a`
19:16:15FromDiscord<Solitude> god gave you `allIt(it)` and you are trying to build hack on hacks
19:16:40FromDiscord<Solitude> you want to have as default argument something that only works on sequences of booleans?

19:17:35FromDiscord<kaddkaka> In reply to @Solitude "god gave you `allIt(it)`": That was the suggestion, that's how pythons `and` and `all` behave.

19:23:29FromDiscord<Rosen> To get a decent answer you need to provide enough context for people to understand what's wrong lmao. I'm assuming the dimensions of the array are 50x50? How are you accessing the array inside the loop? Is the type of `points` `array[50, array[50, int]]` or something else?
19:24:32FromDiscord<Shiba> In reply to @Rosen "To get a decent": Yes?
19:25:28FromDiscord<Rosen> the snippet you sent works fine, and that error has to do with accessing the array, so you didn't provide the context needed to understand the problem

21:01:28FromDiscord<Isofruit> In reply to @Yardanico "https://github.com/cheatfate/nimcrypto can do both": I'm trying to comprehend how hashing in nimcrypto works but I can't really say I'm succeeding.↵So I set up a context object (with a count (?) a state (?) and a buffer (?)), sth sth. digest (?), more unknown steps, out comes the string?↵I don't think I comprehend the documentation or the given examples in there
21:01:51FromDiscord<Isofruit> (edit) "string?↵I" => "string in bytes that I can base64-encode myself?↵I"

23:04:05FromDiscord<hotdog> In reply to @krisppurg "Hiya, Whenever I try": In your json, sticker_items is an array
23:04:20FromDiscord<hotdog> So presumably the type needs to model it as a sew
23:04:27FromDiscord<hotdog> Seq
23:07:39FromDiscord<hotdog> In reply to @Casey.McMahon "is there a way": Haven’t used this command before but you can probably splice the html together if there’s no inbuilt way
23:08:48FromDiscord<Casey.McMahon> I was just going through how the nim compiler builds it's manual and tutorial files, which originates as an `.rst` file
23:09:03FromDiscord<Casey.McMahon> In reply to @hotdog "Haven’t used this command": .
23:09:56FromDiscord<Casey.McMahon> a little confusing, obviously, as it does a whole bunch of other stuff, and isn't documented well
23:10:55*jjido quit (Quit: My MacBook Air has gone to sleep. ZZZzzz…)
23:23:25FromDiscord<Casey.McMahon> I think I'll just use nimibook
23:23:25FromDiscord<Casey.McMahon> https://github.com/pietroppeter/nimibook
23:25:44FromDiscord<geekrelief> I'm using `std/unittest`, and I have a test that wants to check if some code raises an `AssertionDefect` via `raiseAssert`. I realize defects can't be caught, so is there another way to test for failure scenarios?
23:26:32FromDiscord<geekrelief> I guess I could raise an exception instead.
23:29:47FromDiscord<geekrelief> Is it possible to catch an exception coming from a macro?
23:32:39FromDiscord<Isofruit> A macro is merely rendered into your source code at compile time, methinks.↵I'd assume so, since your tests are running after compile time (I think? I'd assume that at least).↵Shouldn't it be possible to just jot down what the fully rendered source code will be and write tests that cover that?
23:32:40FromDiscord<Elegantbeef> No there is not
23:32:44FromDiscord<geekrelief> sent a code paste, see https://paste.rs/iC5
23:33:00FromDiscord<geekrelief> In reply to @Elegantbeef "No there is not": darn thx
23:33:10FromDiscord<Elegantbeef> You should be able to see the defects though with the `expect`
23:33:17FromDiscord<Elegantbeef> https://nim-lang.org/docs/assertions.html#doAssertRaises.t%2Ctypedesc%2Cuntyped
23:33:28FromDiscord<Elegantbeef> You can test with assertions on
23:33:43FromDiscord<Elegantbeef> In some dialects defects are not catchable
23:33:49FromDiscord<geekrelief> ooh thanks for the tip
23:34:13FromDiscord<Elegantbeef> So you can force defects to be catchable i think
23:34:24FromDiscord<Elegantbeef> Not that you should ever do that in real code
23:34:31FromDiscord<Elegantbeef> If you do that in real code i'll find you and break your legs
23:34:35FromDiscord<geekrelief> Right, I'm only doing this for tests
23:34:59FromDiscord<Elegantbeef> That's how it starts!
23:35:19FromDiscord<Elegantbeef> Tests are a gateway drug!
23:35:23FromDiscord<geekrelief> Well you planted the idea in my head, so you started it.
23:36:02FromDiscord<geekrelief> It starts with ideas, turned into words, into actions. It's all your fault!
23:36:32FromDiscord<Elegantbeef> Well it's your knees
23:40:37FromDiscord<geekrelief> sent a code paste, see https://play.nim-lang.org/#ix=3KJq
23:40:54FromDiscord<Elegantbeef> Wait is this at CT or RT?
23:41:00FromDiscord<geekrelief> at compile time
23:41:19FromDiscord<geekrelief> I want error reporting for my macro
23:42:02*sagax quit (Excess Flood)
23:43:23FromDiscord<Elegantbeef> I think the best thing to do is compile files and check the output
23:43:33FromDiscord<Elegantbeef> Like how the Nim stdlib checks for errors
23:43:51FromDiscord<Elegantbeef> `nim check --hints:off yourFile.nim`
23:44:40FromDiscord<Elegantbeef> On a side note, why are you raising errors in a macro
23:44:50FromDiscord<geekrelief> huh ok, not the end of the world, but I'll keep that in mind. Would be nice to have a test tool that handles that.
23:45:08FromDiscord<geekrelief> I want to give better error reporting.
23:45:20FromDiscord<Elegantbeef> So then use `macros.error`
23:45:33FromDiscord<Elegantbeef> raising errors in macros is terrible
23:46:01FromDiscord<geekrelief> ah, thanks. 🙂 it did feel wrong
23:46:22FromDiscord<Elegantbeef> https://github.com/beef331/slicerator/blob/master/src/slicerator.nim#L206-L211 for an example
23:47:15FromDiscord<geekrelief> gotcha, thx
