00:45:45FromDiscord<Girvo> Is a returned seq[byte] from a proc by copy? or is it by ref as its managed? Dumb question I know
00:48:55pchseq is refferential
00:49:00pchopenarray is copied
00:49:01pchiirc
00:50:30pchhowever seqs are also like, they're a reference to a copy usually
00:50:40pchit's just the direct storage in the seq is not the copy

00:52:30FromDiscord<Girvo> Awesome
00:52:39FromDiscord<Girvo> Thats what I was expecting, cheers 🙂
00:55:08FromDiscord<Girvo> I'm having to pass around a lot of `seq[byte]` for the work I'm doing. Good fun, but nice to work with honestly
00:56:45FromDiscord<Elegantbeef> what do you mean?↵(@abdu)

01:18:16FromDiscord<abdu> Works great.. so what insight on quote do, should `var l = newLit 6` be better put inside it or just that ?
01:18:55FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=3SIq
01:18:58FromDiscord<abdu> Thanks for useful contribution
01:19:06FromDiscord<Elegantbeef> In this case there is 0 reason to use a macro
01:19:48FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=3SIr
01:21:42FromDiscord<Girvo> Whats the current workflow for working on Nim itself, say if I wanted to try and fix `createThread` etc. for FreeRTOS on the ESP32?
01:22:23FromDiscord<Elegantbeef> Fork the git repo, follow the build instructions, modify the file, make a PR, profit
01:22:48FromDiscord<Elegantbeef> https://nim-lang.github.io/Nim/contributing.html is useful aswell
01:27:16*kayabaNerve joined #nim
01:31:21FromDiscord<Elegantbeef> Oh also @Girvo `openArray`s are slices so even if they're copied they're just a pointer and len so it's cheap
01:32:02FromDiscord<Elegantbeef> You generally want to use them instead of index slicing if you care about memory usage
01:33:36FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=3SIC
01:36:21FromDiscord<Girvo> Ohhhhhhh neat
01:36:42FromDiscord<Girvo> Alright I might swap the nesper stuff to work with openarray instead. I think it'll be superior for what I'm after, I'll have a play though
01:36:54FromDiscord<Girvo> Cheers! (now drink)
01:37:14FromDiscord<Elegantbeef> Drinky drinky is bad for the health
01:37:55FromDiscord<Girvo> Like _incredibly_ bad lol. I've never understood the "Ballmer Peak" stuff, alcohol makes programming way too difficult for me
01:38:26FromDiscord<Elegantbeef> I've never drank so no clue for me, i do know that alcohol can be a stimulant though
01:39:02FromDiscord<Girvo> Not missing much. I'm stoked that the no-alcohol gins are easily available where I am now. All the taste, none of the downside
01:40:26FromDiscord<Elegantbeef> I'm like the completely wrong person for this area, rural Canada yet I dont drink or do drugs
01:40:53FromDiscord<Girvo> Haha yeah
01:41:01FromDiscord<creikey> https://github.com/treeform/windy/blob/master/src/windy.nim#L10 windy exports vmath here, can I `import windy` but just the exported vmath as I don't want the whole library imported?
01:42:26FromDiscord<Girvo> `vmath` appears to be a separate library, no?
01:43:29FromDiscord<Girvo> Though its not in the nimble requirements list. Likely a sub-req of one of its dependencies?
01:43:47FromDiscord<creikey> In reply to @Girvo "Though its not in": it is yes
01:43:56FromDiscord<creikey> it's a requirement of `windy` and exported from it
01:44:05FromDiscord<creikey> I guess I could just do `requries vmath`
01:44:09FromDiscord<creikey> and import vmath
01:44:12FromDiscord<creikey> and it doesn't install it twice
01:44:14FromDiscord<Girvo> Yeah thats what I'd do if thats what you're after
01:44:52FromDiscord<Girvo> As long as the version requirement matches, it will use the same one
01:45:08FromDiscord<creikey> just checked and it didn't even have a requires vmath in the nimble file so I opened an issue
01:46:30FromDiscord<Girvo> Yeah thats what threw me off
01:46:42FromDiscord<Girvo> And I can't see it in the other requires so far
01:47:28FromDiscord<Girvo> Can you see `vmath` in your `.nimble/pkgs` folder after installing `windy`?
01:53:55FromDiscord<Elegantbeef> Seems it's a forgetten dependancy
01:54:26FromDiscord<Girvo> Yeah, most likely because its by the same author so they've `nimble develop`-ed it
01:54:47FromDiscord<Girvo> I made the same mistake with `nesper` initially lol
01:58:31FromDiscord<Elegantbeef> Yea i've done similar
02:01:43FromDiscord<creikey> I feel like that should be linted for
02:47:57NimEventerNew thread by Mardiyah: The 'for i in ...' loop inside parsing macro , see https://forum.nim-lang.org/t/9020
03:32:29FromDiscord<Kiwids> hi guys. I am coding a small webapp that connected to the backend SQLite DB and using jester to get the request from client. But it seems like somewhere in the thread that is blocking( i have to press `Enter` in console to make the data parse thru). I tried to make all function async, but seems like its still unstable sometimes. I wonder if theres a way for me to find out where exactly the blockage is at
03:34:07FromDiscord<Kiwids> https://media.discordapp.net/attachments/371759389889003532/954221135459921950/unknown.png
03:34:23FromDiscord<Kiwids> this is the API that I was testing and getting stuck...
03:42:30FromDiscord<Kiwids> reduced the code to, still getting a block https://media.discordapp.net/attachments/371759389889003532/954223241986191370/unknown.png
03:43:39FromDiscord<Kiwids> 🤔 could it be the decode
03:45:48FromDiscord<Kiwids> nope...
03:46:35FromDiscord<Kiwids> literaly this gets blocked. might be a console app issue on windows? im sorry guys i am so noob at this... https://media.discordapp.net/attachments/371759389889003532/954224272392478720/unknown.png
03:48:09nrds<Prestige99> You think the echo is blocking execution?
03:49:16FromDiscord<Kiwids> oh lord
03:49:26FromDiscord<Kiwids> 😢
03:50:54FromDiscord<Kiwids> I needa a way to see if the request is actually coming in tho.. 🤔
03:51:24nrds<Prestige99> echo should work fine afaik
03:52:26FromDiscord<Kiwids> hmmm that's so weird... I have two bots just sending get request and it gets blocked. but maybe let me try something to see if its the echo
03:53:01FromDiscord<Kiwids> if its blocked without echoing. I should be able to see it if I send the 3rd request on top of my 2 bots, the server should hang
03:53:58FromDiscord<Kiwids> nope.. it still blocking.
03:57:59FromDiscord<Elegantbeef> Do you have a `readline` somewhere?
03:58:20FromDiscord<Kiwids> yes
03:58:34FromDiscord<Kiwids> everytime when program starts. it asks me if I want to reinitiate the DB
03:58:37FromDiscord<Elegantbeef> Well there is you blocking
03:58:38FromDiscord<Kiwids> you think that's the problem?
03:58:53FromDiscord<Elegantbeef> If it's not in the loop, no
03:59:04FromDiscord<Kiwids> its not
03:59:10FromDiscord<Elegantbeef> But you're describing a `readLine` inside your programs loop
03:59:20FromDiscord<Elegantbeef> Needing to hit enter sounds exactly like a readline in the loop
03:59:26FromDiscord<Kiwids> https://media.discordapp.net/attachments/371759389889003532/954227505680777226/unknown.png
03:59:34FromDiscord<Kiwids> this function I create calls a readLine()
04:00:06FromDiscord<Elegantbeef> Can i see the entire program?
04:00:07FromDiscord<Kiwids> In reply to @Elegantbeef "Needing to hit enter": yeah i know haha. sometimes I need to press `Enter` after 5 get request. sometimes is 2
04:00:31FromDiscord<Kiwids> I am so sorry can't really share the source code.
04:00:37FromDiscord<Kiwids> (edit) "I am so sorry can't really share the ... source" added "full"
04:01:08FromDiscord<Elegantbeef> Cant say much then aside from make sure your stdinIO isnt done in the main loope
04:02:32FromDiscord<Kiwids> yeah! my code looks just like this one https://github.com/dom96/nim-in-action-code/tree/master/Chapter7/Tweeter
04:02:41FromDiscord<Kiwids> as I was reading the book and want to start a small project
04:04:23FromDiscord<Kiwids> https://media.discordapp.net/attachments/371759389889003532/954228751619727390/unknown.png
04:04:46FromDiscord<Elegantbeef> `nim -v`?
04:05:35FromDiscord<Kiwids> https://media.discordapp.net/attachments/371759389889003532/954229055102783578/unknown.png
04:06:04FromDiscord<Kiwids> `nim c --gc:boehm --threads:on -d:windows --app:console -o:Server.exe `
04:06:08FromDiscord<Kiwids> and this is my compiler falg
04:06:12FromDiscord<Kiwids> (edit) "falg" => "flag"
04:06:21FromDiscord<Elegantbeef> What does `renderMain`, `renderTimeline` and `renderLogin` do?
04:06:43FromDiscord<Kiwids> it copies the sql data and put them into a hardcoded html page
04:06:53FromDiscord<Kiwids> and just feed it back to the client iirc
04:07:19FromDiscord<Elegantbeef> So there is 100% no stdin io there in your case?
04:08:19FromDiscord<Kiwids> ` let ok = readLineFromStdin("Previous database file found, do you want to start fresh? [Y/N] ", line)` in createDatbase() I have one. but that's it
04:09:12FromDiscord<Kiwids> and if the previous database file is not there. it won't even promot for user input, I wrapped the readLine under a fileExist()
04:09:17FromDiscord<Kiwids> (edit) "readLine" => "`readLine`" | "fileExist()" => "`fileExist()`"
04:09:50FromDiscord<Elegantbeef> If thats the case this shouldnt be happening
04:09:56FromDiscord<Elegantbeef> But without code i cant say anything
04:10:10FromDiscord<Kiwids> sure thanks! i am also very confused hah
04:10:31FromDiscord<Kiwids> I tried spawn new threads to handle some db tasks. but still no luck
04:10:39FromDiscord<Kiwids> (edit) "tasks." => "tasks(previous async)."
04:10:44FromDiscord<Elegantbeef> Well it will never fix the actual problem
04:10:51FromDiscord<Kiwids> yep
04:11:50*slowButPresent quit (Quit: leaving)
04:12:45FromDiscord<Kiwids> like if I press `Enter`, the server will be working fine for a solid minute https://media.discordapp.net/attachments/371759389889003532/954230855352606741/unknown.png
04:13:07FromDiscord<Kiwids> but it will eventually get block, where no debug info is displayed until the next `Enter`
04:19:05FromDiscord<Elegantbeef> I can suggest going to the nearest well and throw a penny and wish for a solution
04:19:17FromDiscord<Kiwids> sounds like a plan!
04:24:19FromDiscord<Kiwids> `customOverlapped.data.fd == lpCompletionKey.AsyncFD` [AssertionDefect]
04:24:26FromDiscord<Kiwids> got a error and program crashed 🤔
04:24:38FromDiscord<Kiwids> could it be this? https://media.discordapp.net/attachments/371759389889003532/954233846054924308/unknown.png
04:24:55FromDiscord<Kiwids> since I reopen the db file everytime the API gets called?
04:26:05FromDiscord<Elegantbeef> You arent closing the dbconnection
04:26:13FromDiscord<Kiwids> oh fk
04:26:22FromDiscord<Kiwids> I commented some of those line out...
04:26:25FromDiscord<Elegantbeef> So if you open a new one then dont close it that could be an isssue
04:26:37FromDiscord<Kiwids> ye
04:26:54FromDiscord<Kiwids> let me try that
04:27:27FromDiscord<Kiwids> still blocked. let me try to pass as ref
04:27:33FromDiscord<Elegantbeef> Doesnt make sense that `enter` would continue
04:28:02FromDiscord<Kiwids> hmm yeah. it crashed again with db.close()
04:28:06FromDiscord<Elegantbeef> Are you 1000% certain the pressing of enter moves it and it's not just a coincidence?
04:28:20FromDiscord<Kiwids> nvm
04:28:34FromDiscord<Kiwids> In reply to @Elegantbeef "Are you 1000% certain": yeah no haha I can screenshare the flow haha
04:29:13FromDiscord<Elegantbeef> That'd mean to me atleast something is getting your stdin as a file descriptor which would be a very odd bug
04:29:35FromDiscord<Kiwids> 🤔
04:31:06FromDiscord<Bubblie> how do I convert nim code to c++ code?
04:31:27FromDiscord<Elegantbeef> You rewrite it but with 20% more brainpower
04:31:55FromDiscord<Bubblie> I mean like, since nim compiles to c/c++/js I was wondering where to get the output
04:32:10FromDiscord<Elegantbeef> Ah
04:32:14FromDiscord<Kiwids> you can
04:32:21FromDiscord<Kiwids> there is a compiler flag for it i think
04:32:26FromDiscord<Elegantbeef> it's in your `.cache/nim/` or you can do `--nimcache:someDir`
04:33:03FromDiscord<Bubblie> I wonder how neat the output would be... I just started with nim and I love it so far because let me tell you c/c++ is awful
04:33:16FromDiscord<Elegantbeef> It's not meant to be human read
04:33:22FromDiscord<Bubblie> yeah
04:33:24FromDiscord<Elegantbeef> You can do `-d:danger` to make it a bit more readable
04:33:29FromDiscord<Bubblie> I would assume so since its compiling to it
04:33:47FromDiscord<Bubblie> In reply to @Elegantbeef "You can do `-d:danger`": ah okay
04:33:49FromDiscord<Bubblie> thank you
04:34:06FromDiscord<Elegantbeef> Also can use `--gc:arc` or `orc` which will help a bit
04:34:16FromDiscord<Bubblie> I like that I can use c/c++ libraries in nim without having to use c/c++ LOL
04:34:21FromDiscord<Elegantbeef> Dont suggest danger unless you want somewhat clean IR, otherwise use `release`
04:34:35FromDiscord<Bubblie> In reply to @Elegantbeef "Dont suggest danger unless": ah okay, thank you so much
04:34:41FromDiscord<Bubblie> Ill keep that in mind
04:35:24FromDiscord<Bubblie> is there vulkan graphics bindings for nim?
04:35:31FromDiscord<Elegantbeef> Yes
04:35:39FromDiscord<Bubblie> oh wow, that's awesome
04:36:30FromDiscord<Bubblie> There is also NimGL 👀
04:36:34FromDiscord<Bubblie> sick
04:36:52FromDiscord<Elegantbeef> You're a gamedev?
04:37:51FromDiscord<Bubblie> sorta, my main language is java and I mostly make mods for minecraft and applications and I have dabbled with web dev a bit but I really disliked JS
04:38:01FromDiscord<Bubblie> I was going into vulkan to make my own engine of sorts
04:38:03FromDiscord<Bubblie> using C++
04:38:24FromDiscord<Bubblie> but uh well, it wasn't enjoyable using C++
04:38:34FromDiscord<Elegantbeef> Of course not it's C++ 😛
04:38:51FromDiscord<Bubblie> my second option is rust but I don't do well with symbol soup languages
04:38:56FromDiscord<Bubblie> then I found nim yesterday
04:39:21FromDiscord<Elegantbeef> I also use Nim for gamedev, though i also just make macros for arbitrary things for fun
04:39:35FromDiscord<Bubblie> that's awesome!
04:39:51FromDiscord<Bubblie> I hope to use nim for gamedev because of how actually readable things are
04:40:19FromDiscord<Elegantbeef> It's very good for gamedev imo since it has nice macros and a good type system
04:40:28FromDiscord<Bubblie> Nim vulkan has no issues right? Or is there something I need to look out for
04:40:35FromDiscord<Bubblie> In reply to @Elegantbeef "It's very good for": yeah I definitely love the type system here
04:40:51FromDiscord<Elegantbeef> What do you mean vulkan issues?
04:42:05FromDiscord<Elegantbeef> I dont use vulkan, so no clue how nice it is to use with Nim
04:46:58FromDiscord<Bubblie> In reply to @Elegantbeef "What do you mean": as in like, there aren't many problems with the bindings
04:47:00FromDiscord<Bubblie> is my question
04:47:10FromDiscord<Elegantbeef> It should be like using it in C
04:56:33FromDiscord<Equinox> In reply to @Bubblie "my second option is": Symbol soup
04:56:45FromDiscord<Equinox> What does that mean
04:57:01FromDiscord<Elegantbeef> `std::<vector<SomeType<int>>`
04:57:22FromDiscord<huantian> I like my <>
04:57:47FromDiscord<Equinox> In reply to @Elegantbeef "`std::<vector<SomeType<int>>`": That’s not so bad
04:58:00FromDiscord<Equinox> How else would you convey that?
04:58:05FromDiscord<Equinox> What’s the nim way
04:58:05FromDiscord<Elegantbeef> sorry it's `std::vector<std::variant<int, SomeType<int, float>`
04:58:11FromDiscord<Elegantbeef> `seq[SomeType[int]`
04:58:21FromDiscord<Elegantbeef> Perhaps closing both brackets
04:58:37FromDiscord<Equinox> Yeah but that rust is not correct
04:58:40FromDiscord<Elegantbeef> It also uses `` and `&` so it gets fucky
04:58:43FromDiscord<Equinox> You don’t need the std
04:58:50FromDiscord<Equinox> Vector is just vec
04:58:53FromDiscord<Elegantbeef> That's not rust
04:59:08FromDiscord<Equinox> Oh ok
04:59:13FromDiscord<Equinox> We’re doing C++
04:59:35FromDiscord<Equinox> I don’t write C++ I have no reason to defend it
04:59:39FromDiscord<Equinox> Too many things
05:01:57FromDiscord<Elegantbeef> Rust and C++ both have similar symbol noise imo
05:03:06FromDiscord<Equinox> The rust version of that is a bit smaller
05:03:15FromDiscord<Elegantbeef> I mean in general
05:03:33FromDiscord<Equinox> Vec<sometype<i32>>
05:04:03FromDiscord<Equinox> In reply to @Elegantbeef "I mean in general": Probably true
05:05:59FromDiscord<treeform> Crazy Nim bug causing me to pull hair out, I get a segfault in reading and writing to some UncheckedArrays, but if I add some dummy code to slow down to loop it works fine... in fact! just doing 17 inc'ers `for z in 0 ..< 17: counter += 1` works but 16 inc'ers `for z in 0 ..< 16: counter += 1` not enough slow down. What kind of crazy things is this!
05:06:30FromDiscord<Elegantbeef> Code causing the issue?
05:08:36FromDiscord<treeform> sent a code paste, see https://play.nim-lang.org/#ix=3SIV
05:08:44FromDiscord<treeform> its a simple copy loop
05:09:05FromDiscord<treeform> Can C cause undefined behavior when copying two overlapping 64 bit numbers?
05:09:10FromDiscord<Elegantbeef> It's syncronous code?
05:09:18FromDiscord<treeform> yes, no threads, no async
05:09:32FromDiscord<treeform> fine in orc and arc, but not refc or none
05:09:52FromDiscord<treeform> if uncomment the `for z in 0 ..` it works
05:10:15FromDiscord<Elegantbeef> Is `dst` or `dst2` a seq?
05:10:35FromDiscord<treeform> no its a `ptr UncheckedArray[uint8]`
05:10:47FromDiscord<Elegantbeef> And it doesnt point to a sequence?
05:11:01FromDiscord<treeform> yes
05:11:04FromDiscord<treeform> it comes from a seq
05:11:16FromDiscord<treeform> I though it was getting moved or something
05:11:20FromDiscord<Elegantbeef> `gcref` and `gcunref` the see before and after the op
05:12:01FromDiscord<treeform> I keep the seq around so it does not get collected
05:12:45FromDiscord<treeform> but I could GCref it so it stays in memory always for ever
05:14:45FromDiscord<treeform> `GC_ref(dst)` does not help
05:22:40FromDiscord<Kiwids> aight. just spend some time reading the nim-forum source code..
05:22:44FromDiscord<Elegantbeef> You do ensure the size is the same or less than right?
05:22:58FromDiscord<Kiwids> I willl try to adjust my db : dbConn to see if that's the problem
05:24:55FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=3SIX
05:25:51FromDiscord<Kiwids> also I tried to search for `runForever()` in the source code for Nim-Forum but I couldn't find an
05:25:52FromDiscord<Kiwids> (edit) "an" => "any"
05:25:55FromDiscord<Kiwids> (edit) "also I tried to search for `runForever()` in the source code for Nim-Forum but I couldn't find any ... " added "🤔"
05:26:29FromDiscord<Elegantbeef> @treeform\: does the above behave differently?
05:29:09FromDiscord<treeform> dst is not len is mod 8
05:29:29FromDiscord<treeform> we need to be able to access any index not just the uint64 steps
05:29:39FromDiscord<Elegantbeef> Well there you go if dst's len isnt mod 8 you're doing unsafe memory access
05:29:41FromDiscord<treeform> with bytes
05:29:42FromDiscord<treeform> sent a code paste, see https://paste.rs/MrG
05:30:06FromDiscord<treeform> we just want to do it faster
05:30:11FromDiscord<treeform> by going 8 bytes at a time
05:30:14FromDiscord<Elegantbeef> If you're writing 8 bytes to a seq that only has allocated 3 bytes you're going to destroy it
05:30:24FromDiscord<treeform> we make sure its long enough
05:30:39FromDiscord<Elegantbeef> You should figure out what size fits the best IE `8 -> 4 -> 2 -> 1`
05:30:51FromDiscord<treeform> the byte works
05:31:04FromDiscord<treeform> but uin16, uint32, uint64 does not
05:31:14FromDiscord<Elegantbeef> How does the above code make sure it's long enough
05:31:17FromDiscord<Elegantbeef> It's offsetting it by 8 bytes writing the 8 bytes from the right
05:31:35FromDiscord<Elegantbeef> Any remainder will be writing after the sequence
05:31:52FromDiscord<Bubblie> does nim have algebraic data types?
05:32:03FromDiscord<Elegantbeef> So if you dont use the largest size that is smaller than dest length it's going to fail
05:32:13FromDiscord<Elegantbeef> It has object variants which are manually declared tagged unions
05:32:23FromDiscord<Elegantbeef> There are also things like https://github.com/alaviss/union
05:33:01FromDiscord<Elegantbeef> In the above case you said the length is not mod 8 which means you write 8 bytes then you attempt to write 8 more and say it's 15 bytes, you have 1 byte going onto some other heap memory
05:33:35FromDiscord<Elegantbeef> Atleast given what you've explained, what you're doing is wildly unsafe
05:34:48FromDiscord<treeform> @ElegantBeef I think you helped me out! I was going to link you the file https://github.com/guzba/zippy/blob/master/src/zippy/inflate.nim#L216-L224 but turns out it has a newer version that fixes the issues that I did not see. Thanks!
05:35:16FromDiscord<treeform> The `if copyTo < 0` is strange but its a cheap way to make it work.
05:37:11FromDiscord<Elegantbeef> I mean i clearly didnt help out at all, i just made you look at it 😛
05:40:01FromDiscord<Elegantbeef> I still dont think `copy64` is actually safe, but i'm a fool
06:05:12FromDiscord<treeform> We been using copy64 in a ton of places. But maybe it some sort of unsafe behavior which works 99.999% of the time.
06:05:18FromDiscord<Bubblie> Can you have nim without garbage collection?
06:05:27FromDiscord<treeform> This is very strange for us.
06:05:30FromDiscord<Bubblie> And manually memory manage
06:05:37FromDiscord<Elegantbeef> You can but there isnt much point to
06:05:54FromDiscord<Elegantbeef> Arc/Orc give you a good memory management system and isnt a typical GC
06:06:04FromDiscord<Elegantbeef> Orc is RAII like memory management with a cycle collector
06:06:12FromDiscord<treeform> We do manually memory manage in tight loops...
06:06:20FromDiscord<treeform> (edit) "manage" => "management"
06:06:39FromDiscord<Bubblie> Is there any docs on nim’s memory management system?
06:06:49FromDiscord<Elegantbeef> I mean you wont really notice if what i think is happening is happening, since you're writing to random spots on the heap
06:06:56FromDiscord<Rika> https://nim-lang.github.io/Nim/mm.html
06:07:34FromDiscord<Elegantbeef> Since you're writing in blocks of 8 i think you're accidently ruining data after the sequence, though i'm not 100% certain
06:08:06FromDiscord<Elegantbeef> Like the `<=` 16 here is very very suspect to me https://github.com/guzba/zippy/blob/master/src/zippy/inflate.nim#L204-L206
06:08:45FromDiscord<Elegantbeef> I know it's min size is 16 based off line 200, but i dont see anything smaller than 8 bytes being written
06:09:13FromDiscord<Bubblie> I was just wondering how memory management would play out in nim if I needed it, like if I wanted to run nim in something relatively old and I couldn’t use a gc in it
06:09:16FromDiscord<Elegantbeef> So like what happens if your source is not divisible by 8
06:09:51FromDiscord<Elegantbeef> You'd use it like c with `alloc` and `dealloc` but Nim's `arc` is RAIII like so is generally very low overhead
06:09:52FromDiscord<treeform> In reply to @Elegantbeef "Since you're writing in": I am pretty sure we don't write beyond the allocated memory. We have asserted that to death.
06:10:05FromDiscord<Rika> In reply to @Bubblie "I was just wondering": As many people have already told you ARC isn’t a “GC” exactly
06:10:34FromDiscord<Elegantbeef> I've used arc on the rpi pico, it's quite easy and lovely to use
06:11:02FromDiscord<Elegantbeef> It's a deterministic memory mangement system that cannot handle cycles so pretty ideal for embedded
06:12:00FromDiscord<treeform> I also like arc for games and such
06:12:26FromDiscord<Elegantbeef> I'd say use orc by default, if you dont need it it's not going to cost you anything
06:12:27FromDiscord<treeform> I wish I could run my stuff with orc enable that only tells me when it finds cycles I forgot about, and then release with arc.
06:13:11FromDiscord<Bubblie> In reply to @Rika "As many people have": Yeah
06:13:15FromDiscord<Elegantbeef> Probably could add a `--nimDebugOrc` which echos some info for cycles
06:13:28FromDiscord<Elegantbeef> Dont know how hard that'd be to add to the compiler
06:13:32FromDiscord<Bubblie> So ORC is more manual than ARC right?
06:13:35FromDiscord<Elegantbeef> I've not touched memory related stuff
06:13:36FromDiscord<Elegantbeef> No
06:13:49FromDiscord<Elegantbeef> Arc is RAII, so it doesnt have a cycle collector
06:13:53FromDiscord<Bubblie> OH
06:13:55FromDiscord<Elegantbeef> Orc is Arc + Cycle collector
06:13:56FromDiscord<Bubblie> Alright
06:14:02FromDiscord<Bubblie> yeah got it
06:14:35FromDiscord<Elegantbeef> So arc will insert RC destroy calls into your program and your entire GC will be a static placement of decrements and calls to destroy
06:14:43FromDiscord<Elegantbeef> So with arc you know where things are going to be destructed
06:15:14FromDiscord<Bubblie> Thats really cool
06:15:16FromDiscord<Elegantbeef> Worth noting that the GCs only effect `ref`, `seq` and `string`
06:15:30FromDiscord<Bubblie> This language is great oml
06:15:57FromDiscord<Elegantbeef> `ptr` is always manually managed which can point to the GC'd stuff if you know it's safe(It's a system programming language afterall, need unsafe features)
06:16:25FromDiscord<Elegantbeef> You havent even experienced the best part, introspective macros which allow you to abstract low level code to a high level api 😛
06:16:52FromDiscord<Rika> Beef here tends to go overkill on those though so practice moderation
06:17:01FromDiscord<Elegantbeef> What's moderation?
06:17:11FromDiscord<Elegantbeef> Everything is a nail and i have a macro hammer
06:19:42FromDiscord<Elegantbeef> To be fair rika my largest Nim package requires macros heavily, so.... uhhh it'd be a disservice if i wasnt proficient in macros!
06:22:10FromDiscord<Bubblie> Lol
06:27:49FromDiscord<Rika> thats not my point
06:27:56FromDiscord<Rika> its fine do be proficient but you're trigger happy
06:28:22FromDiscord<Elegantbeef> Did someone say macro
06:29:41FromDiscord<Elegantbeef> Jokes aside, i do try to use the least complex tool
06:30:11FromDiscord<Bubblie> Im gonna try nim-vulkan tommorow
06:30:26FromDiscord<Elegantbeef> Have fun writing 10000 loc for a single triangle
06:30:33FromDiscord<Bubblie> Try to render a triangle without having to type 10000 lines
06:30:41FromDiscord<Bubblie> LMAO
06:30:52FromDiscord<Bubblie> We said the same thing kinda
06:31:03FromDiscord<Bubblie> Yeah to render a triangle it takes a literal bible
06:31:06FromDiscord<Elegantbeef> https://github.com/beef331/truss3d/blob/master/src/truss3D.nim#L99-L131 cube is easy 😛
06:31:27FromDiscord<Elegantbeef> Yea my opengl/sdl2/assimp abstraction is like 1k loc so far i think
06:31:43FromDiscord<Bubblie> Vulkan java vulkan rust vulkan C++ arent all that better in verbosity
06:31:47FromDiscord<Bubblie> So like
06:32:20FromDiscord<Elegantbeef> Vulkan is just verbose, so it's just going to be getting that to a point you can happily use it
06:32:33FromDiscord<Elegantbeef> Personally i can barely stand the opengl API so i dont know how people write vulkan
06:33:09FromDiscord<Bubblie> Well, I hate OpenGL because of opengl’s state machine
06:33:11FromDiscord<Bubblie> It drives me mad
06:33:26FromDiscord<Bubblie> The reason people use vulkan is to avoid gl’s state
06:33:46FromDiscord<Bubblie> Because oh my god, I had to deal with opengl state before for one of my projects
06:33:48FromDiscord<Bubblie> Horrible
06:34:26FromDiscord<Elegantbeef> My present API is more like raylib so it's hardly an issue

12:53:57FromDiscord<auxym> deep, opaque class hierarchies and lots of hidden mutable state are things that OOP tend to migrate towards, but I can guess can be avoided if you are careful

22:17:33FromDiscord<Bubblie> Sometimes coding doesn't need to have a purpose, it can just be cursed

22:17:55FromDiscord<Bubblie> In reply to @Elegantbeef "https://github.com/arnetheduck/nbindgen": 👁️👁️
22:18:02FromDiscord<Bubblie> I will take a look at this
22:18:08FromDiscord<Bubblie> 62 stars
22:18:09FromDiscord<Bubblie> woah
22:18:15FromDiscord<Bubblie> oh wait
22:18:19FromDiscord<Bubblie> 61 contributers
22:18:33FromDiscord<Bubblie> now 63 stars
22:19:13FromDiscord<DeltaPHC> Still goes through the C ABI. It just automates some of it for you
22:20:16FromDiscord<Bubblie> thats still great
22:22:58FromDiscord<Bubblie> also why do anti viruses hate nim exactly
22:23:52FromDiscord<Elegantbeef> Viruses are written in Nim is what some people think
22:23:58FromDiscord<Elegantbeef> So they found a pattern and it's the nim code 😜
22:26:16FromDiscord<Bubblie> damn
22:26:28FromDiscord<Bubblie> I mean, arent viruses commonly made in C and C++ to though
22:26:33FromDiscord<Bubblie> (edit) "to" => "too"
22:26:59FromDiscord<Bubblie> people really using the nim lang for evil ig
22:27:24FromDiscord<Elegantbeef> Well Nim is a high level language that's nice to write and creates small self contained binaries
22:27:54FromDiscord<Bubblie> yeah makes total sense
22:27:56FromDiscord<Bubblie> but damn
22:39:59FromDiscord<Phil> Ah, we on the topic of how Antiviruses are somewhat bs sometimes?
22:41:41FromDiscord<Phil> sent a long message, see http://ix.io/3SNr
22:42:33*kenran quit (Quit: WeeChat info:version)
22:43:03FromDiscord<Phil> I'm semi certain that the details are a bit more complicated than I laid them out here but afaik the gist is correct
22:43:59FromDiscord<Phil> In reply to @Bubblie "Java is the main": Oh hey, a fellow java drinker
22:45:27FromDiscord<Bubblie> In reply to @Isofruit "Think of it more": yeah
22:45:35FromDiscord<Bubblie> but it is definitely saddening to have nim's name tarnished like this
22:45:46FromDiscord<Bubblie> I was talking about nim in a server today
22:45:55FromDiscord<Bubblie> and one of the first things brought up about it is the anti viruses made for it
22:46:06FromDiscord<Bubblie> (edit) removed "anti" | "for it" => "with ti"
22:46:09FromDiscord<Bubblie> (edit) "ti" => "it"
22:46:21FromDiscord<Bubblie> In reply to @Isofruit "Oh hey, a fellow": YOOO you develop in java as well? Lets go
22:47:05FromDiscord<Phil> Webdev, Spring, Elasticsearch, Mysql, mongo etc.
22:48:02FromDiscord<Bubblie> I use java for backend dev, and for minecraft mods
22:48:10FromDiscord<Bubblie> Also for like
22:48:22FromDiscord<Bubblie> software dev too but
22:48:33FromDiscord<Bubblie> for game dev I kind of felt as if I shouldn't use it as much
22:48:36FromDiscord<Bubblie> especially with graphics
22:48:48FromDiscord<Bubblie> lwjgl can be a real pain
22:48:54FromDiscord<Phil> I think the java GC makes consistent framerates near impossible
22:48:58FromDiscord<Bubblie> fr
22:49:00FromDiscord<Bubblie> it does
22:49:16FromDiscord<Bubblie> don't get me wrong java has never failed me with software development and servers and such
22:49:17FromDiscord<Bubblie> but
22:49:22FromDiscord<Bubblie> graphics? uh
22:49:26FromDiscord<Bubblie> not the BEST per say
22:49:28FromDiscord<Bubblie> its doable
22:49:29FromDiscord<Bubblie> but
22:49:36FromDiscord<Phil> Not great, yeah
22:49:39FromDiscord<Phil> I dabbled in swing once
22:49:39FromDiscord<Bubblie> yeah
22:49:41FromDiscord<Phil> I ran screaming
22:49:43FromDiscord<Bubblie> oh no swing
22:49:45FromDiscord<Bubblie> Im so sorry
22:50:32FromDiscord<Phil> Since then I've learned the joys of just using browser-tech for GUIs and the backend just as a REST API
22:51:27FromDiscord<Phil> As apparently the gnome desktop also uses JS for a lot of stuff I'm starting to feel tempted to find a gnome-project though

22:51:53FromDiscord<creikey> sent a code paste, see https://play.nim-lang.org/#ix=3SNu
22:51:58FromDiscord<Bubblie> In reply to @Isofruit "As apparently the": I didnt know gnome used js a lot
22:52:07FromDiscord<Elegantbeef> dont convert to GVec2
22:52:35FromDiscord<Phil> In reply to @Bubblie "I didnt know gnome": Me neither, I was very surprised to find JS and CSS files in gnome extension folders. You can google GJS, it's essentially a node-like thingy with a lot of bindings to gnome libs
22:52:50FromDiscord<creikey> In reply to @Elegantbeef "dont convert to GVec2": without it there's still an error
22:53:13FromDiscord<creikey> sent a code paste, see https://play.nim-lang.org/#ix=3SNv
22:53:22FromDiscord<Elegantbeef> vec2 is float32
22:53:26FromDiscord<creikey> ahhhh
22:53:39FromDiscord<Elegantbeef> do `rotate(120.0f...`
22:53:50FromDiscord<creikey> float64 to float32 converter?
22:54:01FromDiscord<creikey> the worst idea of all time
22:54:11FromDiscord<Elegantbeef> That wouldnt solve it
22:54:18FromDiscord<Elegantbeef> The issue is the `mat3` is a float64
22:54:27FromDiscord<creikey> In reply to @Elegantbeef "The issue is the": mat3 float 64 to mat3 float 32 converter
22:54:35FromDiscord<Elegantbeef> There you go 😛
22:54:43FromDiscord<Elegantbeef> Or you know just write `d` instead of `.0`
22:54:46FromDiscord<Elegantbeef> or `f`

23:20:13FromDiscord<Equinox> Hey does anyone know what the naming conventions in nim are?
23:20:42FromDiscord<Elegantbeef> lower camel case procedures, pascal cased types
23:22:36FromDiscord<Equinox> In reply to @Elegantbeef "lower camel case procedures,": Thank you
23:22:54FromDiscord<Elegantbeef> https://nim-lang.org/docs/nep1.html for all your conventional needs
23:23:16FromDiscord<Elegantbeef> Nim has style insensitivity so aslong as you start procedures with lower case and types with uppercase you'll be fine in my books

23:34:43FromDiscord<luteva> The nim tutorial says that "Usually types with inheritance are also marked as ref types even though this isn't strictly enforced."↵So why is it usual to use a ref type? Why shouldn't you use a value type in inheritance? What is the disadvantage of using a value type in inheritamce?
23:35:24*Gustavo6046 quit (Ping timeout: 252 seconds)
23:37:44FromDiscord<Elegantbeef> A value type loses information on conversion
23:37:59FromDiscord<Elegantbeef> So unless you're ok with that it's highly suggested to use `ref`
23:39:58FromDiscord<luteva> do you have any example?↵which information is lost on conversion? You mean the runtime type information?
23:40:12FromDiscord<Elegantbeef> sent a code paste, see https://paste.rs/z1x
23:40:35FromDiscord<Elegantbeef> In the above case since `A` is a value type, `c` is lost on conversion to `A`
23:40:54FromDiscord<Elegantbeef> And you cannot convert from `A` to `B` since value type conversion chops fields off
23:41:20FromDiscord<luteva> ahhh ok! thanks!
23:41:24FromDiscord<Elegantbeef> This all comes from the fact non refs are stack variables and as such you cannot fit `C` in place of `A`
