03:13:16FromDiscord<codic> does posix.onSignal use the double pipe thing? because heap allocations usually work but are "unsafe" so you shouldn't do them in a regular signal handler, instead you can use the double pipe trick
03:13:24FromDiscord<codic> I have no idea wtf handle_signal that it calls is, I can't find any docs on it

04:26:45*narimiran joined #nim
04:29:54FromGitter<bung87> @haxscramper I want use a module that module path is runtime determined , so am wonder how to call that module'proc
04:31:35FromDiscord<haxscramper> You can't use runtime module paths
04:32:03FromDiscord<haxscramper> Jim is statically typed, so at best you can embed nimscript compile generates string.
04:32:12FromDiscord<haxscramper> (edit) "Jim" => "Nim"
04:32:15FromDiscord<Rainbow Asteroids> what about a dynamic library, where you export to C ABI?
04:32:17FromDiscord<ElegantBeef> We all see the jim
04:32:28FromDiscord<haxscramper> Yeah, I'm on the phone right now
04:32:35FromDiscord<Rainbow Asteroids> you gotta add Nim to your autocorrect, lol
04:33:01FromDiscord<ElegantBeef> What about a dynamic library, module import path isnt runtime based
04:34:43FromGitter<bung87> ok, so I need collected all procs that need export and compile it to dynlib
04:34:46FromDiscord<Rika> In reply to @haxscramper "Nim is statically typed,": Jim
04:34:49FromDiscord<Rika> Hehe
04:35:26FromDiscord<Rainbow Asteroids> maybe i misintpereted the question. if the path of the module is determined at runtime, wouldn't you need a dynamic library?
04:35:28FromDiscord<haxscramper> In reply to @Rika "Jim": r/contagiouslaughter material
04:35:59FromDiscord<haxscramper> In reply to @Rainbow Asteroids "maybe i misintpereted the": No, module path is a part of syntax, do even dynamic library can't fix that
04:36:16FromDiscord<ElegantBeef> Yea modules do not exist at runtime, so there is no module path there
04:36:58FromDiscord<haxscramper> Dynamic library would allow you to substitute different implementation of the compiled C procedure for example, but when you write nim you would still have to import procs from somewhere.
04:37:38FromGitter<bung87> dyn lib is easy solution, I get it.

10:05:40planetis[m]nvm life is good, last few days I have found more bugs than wrote any code
10:05:46FromDiscord<impbox [ftsf]> first request works after starting the client, but often subsequent attempts trigger it
10:09:53FromDiscord<haxscramper> In reply to @Varriount "Araq: I was reading": On discord it is `@Araq`, colon version pings IRC user

10:12:58PMunchWe get pinged as long as our names are mentioned
10:13:27PMunchplanetis[m], did you figure it out?
10:15:43PMunch@impbox, are you trying to fix the Nim IRC bots?
10:15:51PMunchSo we can move to Libera
10:17:44planetis[m]nope i have no idea how to rewrite it, in order to work
10:18:11planetis[m]i hope we move to matrix and dump irc altogether
10:19:48FromDiscord<impbox [ftsf]> nah, making a discord bot for my game's leaderboards
10:19:58FromDiscord<impbox [ftsf]> it works great but dies after getting that error a lot

10:20:56PMunchThat's the thing I like about IRC, the extremely low bar of entry (don't even need to register anywhere)
10:21:24PMunchAaah, that's cool @impox!
10:21:54planetis[m]then stay on top of it, so it behaves
10:22:57planetis[m]well how about all the spammers? they dont have to register either
10:23:23PMunch@impbox, have you seen this: https://github.com/nim-lang/Nim/issues/7316
10:23:39PMunchplanetis[m], better to have the occasional spammers than to not have any users
10:24:21PMunchIRC is really nice because you can just link to a web-chat and make it possible for anyone to ask for help even without registering
10:24:41PMunchThat's how I started using it
10:25:15PMunchInstalled a Linux distro and it had a "Get help" button which just launched an IRC client that auto-joined the distros IRC channel
10:26:22FromDiscord<impbox [ftsf]> @PMunch yeah, i saw that, but not much info on the cause or how to solve it
10:26:34FromDiscord<impbox [ftsf]> and i'm only dealing with a single connection
10:26:47FromDiscord<impbox [ftsf]> well very few connections
10:27:21PMunchI'm pretty sure it's just the socket that fails or some other network error. You might be fine catching it and just retrying or something
10:31:11FromDiscord<impbox [ftsf]> hmm it's happening in async land, i'm not sure where i can catch it except at top level
10:31:44PMunchOh wait, it's inside async..
10:31:52PMunchYeah that might be tricky..
10:31:59FromDiscord<impbox [ftsf]> actually... it's in httpclient
10:32:18FromDiscord<impbox [ftsf]> my bot makes an API request when it receives a command, maybe it's the API request failing

10:38:36PMunchIt can also measure tea
10:38:49FromDiscord<Rainbow Asteroids> maybe it warns if your cup of water becomes too warm 🤔
10:39:10PMunchBut realistically the Venn diagram of developers and non-coffee drinkers gotta be vanishingly small :P
10:39:21PMunchHmm, it could
10:39:46PMunchCurrently I'm investigating running it off-of the heat in the cup using a Peltier element though
10:39:59PMunchAnd that wouldn't work with cold water going warm
10:40:12FromDiscord<Rainbow Asteroids> In reply to @PMunch "But realistically the Venn": im special ☺️
10:40:35FromDiscord<Rainbow Asteroids> is the heat difference that great?
10:41:00FromDiscord<Rika> i dont drink anything for the morning; i drink cola in the evening
10:41:03PMunchThat's what I'm trying to gauge
10:41:45PMunchThe problem is that the duck needs to stay water-tight, but it felt like adding Qi-charging, a battery pack, and all that jazz was a bit overkill :P
10:42:01PMunch@Rika, Cola is soo bad for you though..
10:42:11FromDiscord<Rika> mhm and coffee isnt
10:42:12FromDiscord<Rainbow Asteroids> but it tastes soo cood
10:42:16FromDiscord<Rainbow Asteroids> (edit) "cood" => "good"
10:42:28FromDiscord<Rika> you've convinced me 😐
10:43:40PMunchCoffee at least doesn't have a huge amount of sugar and acids messing up your teeth and giving you a lot of empty calories
10:44:24PMunchSure high doses of caffeine and cholesterol (depending on how you brew it, I do filter coffee so this isn't much of a concern) isn't great either
10:45:25ormiretcan run little stirling engines off a mug of coffee, could possibly do something with one of them to get notification at a certain temp (or harvest the energy to run electronics to beep) https://smile.amazon.co.uk/Temperature-Stirling-Engine-Motor-Education/dp/B071G7SXVX

15:18:40*fputs joined #nim
15:20:11FromDiscord<ajusa> > sample size of 3
15:21:38FromDiscord<treeform> I doubt it, looking through stats on google (USA only I think) 75-80% of the people like coffee and like 60% drink it everyday. But many people like cream/milk flavored coffee rather then "coffee" itself. Nim community is bigger in EU, it looks like Scandinavia drinks way way more coffee then USA. If I where to put my finger on it I would guess that you will find ~5% don't like coffee and ~20% don't drink it often.
15:22:17FromDiscord<treeform> We should put that on our next Nim pool.
15:22:25FromDiscord<treeform> (edit) "pool." => "pole."
15:26:52FromDiscord<Gary M> Nim doesn't have pointer arithmetic outside of casting to ptr UncheckedArray[T] right
15:27:27FromDiscord<treeform> In reply to @Gary M "Nim doesn't have pointer": Not really but you can write one in like 10 lines of nim code.
15:27:41FromDiscord<Gary M> one what
15:27:49FromDiscord<treeform> pointer arithmetic
15:27:57FromDiscord<treeform> define + [] - for poitners
15:28:03FromDiscord<treeform> (edit) "poitners" => "pointers"
15:28:03FromDiscord<Gary M> ah right.
15:28:18FromDiscord<Gary M> The issue is I'm allocating multiple types within a single alloc0 right
15:28:42FromDiscord<Gary M> so I have to offset lenOfA then lenOfB etc for each array
15:29:11FromDiscord<Gary M> so the pointer arithmetic has to be a little more manual 😄
15:29:44FromDiscord<treeform> yeah so you allocate the block, cast the pointer to uint64 or some thing, do your math, cast it to the type you need?
15:30:32FromDiscord<treeform> I was doing that exact thing yesterday... it works.
15:31:29FromDiscord<Gary M> I'll figure it out 😄 I was just hoping there was maybe some pointer arithmetic thing I was missing.
15:32:45FromDiscord<treeform> In first year of Nim defined + [] - for pointers, in second year of nim I mostly used UncheckedArray, now i just cast uint64 here and there...
15:32:53FromDiscord<treeform> (edit) "In first year of Nim ... defined" added "I"
15:33:17FromDiscord<Gary M> I'm not following the casting the uint64 bit
15:33:24FromDiscord<Gary M> (edit) "the" => "to"
15:37:25FromDiscord<treeform> In reply to @Gary M "I'm not following the": https://play.nim-lang.org/#ix=3pmu
15:37:35FromGitter<kaushalmodi> Gary M: Try `nimble install ptr_math`
15:37:57FromGitter<kaushalmodi> https://kaushalmodi.github.io/ptr_math/
15:39:17FromDiscord<treeform> Yeah I had a similar thing: https://github.com/kaushalmodi/ptr_math/blob/main/src/ptr_math.nim I bet if you remove the comments, examples and tests its like 10 lines of code.
15:39:43FromDiscord<treeform> I just do `cast[uint64](dataPtr) + 4` now days
15:40:02FromDiscord<Gary M> the uint64 trick is pretty cool, I'll experiment more with that 😄
15:41:10FromDiscord<treeform> Maybe casting to int is better as its will support 32 bit platforms.
15:41:28FromDiscord<treeform> I don't have a good way tot test 32bit platforms though
15:42:54FromDiscord<Gary M> I can't think of any modern 32 bit targets 😄
15:43:15FromDiscord<treeform> WASM
15:44:37FromDiscord<Gary M> Fair.
15:45:01FromDiscord<Gary M> Pretty unfortunate that web games all but died with flash save for the occasional itch demo
15:45:40FromDiscord<Gary M> html5 and webgl is more than capable but the community isn't there at all like it was when sites like newgrounds and kongregate were at their peak
15:46:19FromDiscord<treeform> Many of the .io games have millions of players I would not dismiss that.
15:46:36FromDiscord<Gary M> another fair point 😄
15:47:02FromDiscord<Gary M> Just quite different than Flash, still.
15:47:15FromDiscord<treeform> I made a webgame but I had more luck getting my game out there on steam (I just used electron).
15:47:30FromDiscord<treeform> I will probably not make a webgame again.
15:47:40FromDiscord<Gary M> a lot of that style of free/freemium games moved to mobile
15:48:00FromDiscord<treeform> But still many people played the webgame part because they where in school or only had chromebooks.

15:56:12FromDiscord<Gary M> well that's pretty cool
15:58:12FromDiscord<Gary M> the tricky part now will be making these tightly packed arrays resizable 😄
15:58:55FromGitter<kaushalmodi> treeform: Credit for that goes to https://forum.nim-lang.org/t/1188#7366 ⏎ ⏎ I just packaged that code and made it more ergonomic (templates -> proc) and beginner-friendly (examples and docs)
15:59:30FromDiscord<Gary M> however the constraint here is that each allocated array of types is the same length
16:01:19FromDiscord<treeform> In reply to @Gary M "I can't think of": Maybe this looks cleaner: https://play.nim-lang.org/#ix=3pmC
16:02:07FromDiscord<Gary M> Yeah, I'm using ByteAddress and +% now, seems more proper
16:05:28FromGitter<kaushalmodi> Gary M: Why not make your code generic and let `sizeof(T)` figure out your offset jumps
16:05:33FromDiscord<treeform> kaushalmodi, I like the way the original forum post kept it in a "danger" block sort of.
16:05:37FromGitter<kaushalmodi> I see that you are doing manual calcs in your code
16:06:00FromGitter<kaushalmodi> > kept it in a "danger" block sort of. ⏎ ⏎ I had it that way originally, until I realized that that block did nothing
16:06:38FromDiscord<treeform> I like that its for me to basically go here is the "crazy" section
16:06:38FromGitter<kaushalmodi> the templates defined inside that original `ptrMath` template got leaked out to the global namespace, until the internal templates got embedded inside `block:`
16:06:51FromDiscord<treeform> oh they would leak?
16:07:11FromGitter<kaushalmodi> it not "leak" technically.. it's how templates work
16:07:34FromGitter<kaushalmodi> stuff inside templates is equivalent to copy-pasting that stuff manually, like C macros
16:07:55FromDiscord<treeform> yeah
16:08:00FromGitter<kaushalmodi> you can contain that using `block:` but that prevented runnableExamples and docs to run within 😁
16:08:24FromGitter<kaushalmodi> I thought that I was anyways running the "leaked" version for a long time and nothing hurt, so I got rid of that template nesting
16:09:10FromGitter<kaushalmodi> I have documented the issues with nested template approach here: https://github.com/kaushalmodi/ptr_math/issues/1
16:09:46FromDiscord<treeform> So some thing like this will not work? https://play.nim-lang.org/#ix=3pmM
16:10:44FromGitter<kaushalmodi> In your example, the ptr =, -, etc will now work outside the dragons: block too :D
16:11:12*rockcavera quit (Remote host closed the connection)
16:12:35FromGitter<kaushalmodi> the main thing that triggered me to remove that API was that I could not have ptrMath: block appear twice in the same scope. Because the first call, already defined the inner templates in the main scope
16:12:37FromDiscord<treeform> it appears not to work outside the dragon block: https://play.nim-lang.org/#ix=3pmO
16:12:58FromGitter<kaushalmodi> ah, because you have `block:`
16:13:29FromDiscord<treeform> yeah that fixes, but prevents locals from leaking
16:13:36FromDiscord<treeform> which one would like
16:13:36FromGitter<kaushalmodi> As I mentioned earlier, I disliked block: as I could not have runnableExamples in the inner templates (you know, I love docs quite too much)
16:14:20FromGitter<kaushalmodi> also I realized that have `+` etc in global scope did not hurt anything.. it was leaking in the outer scope for a while as I did not have block: originally
16:15:22FromGitter<kaushalmodi> If there's a real need for localized declarations of ptr math procs, I can always add those templates back.
16:17:02*Len[m]2 joined #nim
16:17:18FromDiscord<treeform> I see, yeah, I think your solution is probably best one, given the constraints.
16:17:40FromDiscord<treeform> I would change them to inline functions or back to templates to make them faster.
16:17:55FromDiscord<treeform> function overhead is slow, inline functions are slower them templates for some reason.
16:18:06FromGitter<kaushalmodi> > I would change them to inline functions ⏎ ⏎ I didn't even consider that. I will give that a try
16:18:41FromDiscord<treeform> Or back to templates, templates are faster then inline functions
16:18:47FromGitter<kaushalmodi> > function overhead is slow, inline functions are slower them templates for some reason. ⏎ ⏎ Oh really? I went through converting all templates to procs because I have been reading that you should read procs if possible
16:19:00FromGitter<kaushalmodi> *write procs
16:19:12FromGitter<kaushalmodi> heh, not sure how write got typoed as read
16:19:16FromDiscord<treeform> I think that is true, unless you benchmark it to not be the case
16:19:23FromDiscord<Gary M> I actually brought up that issue about template speed, I believe heh
16:19:30FromDiscord<Gary M> or rather, inlined proc speed
16:19:37FromDiscord<treeform> Do you have a ticket, i would watch
16:19:50FromDiscord<Gary M> even with opt:speed and danger builds, though it gets a lot closer
16:19:54FromDiscord<Gary M> No I don't.
16:20:10FromDiscord<Gary M> I figure I might also be incorrect with my reasoning somewhere.
16:20:21FromDiscord<treeform> To me its very strange that inline proc is slower them template, feel like its a bug/optimization nim compiler can make.
16:20:23*nixnet08 joined #nim
16:21:35FromDiscord<treeform> kaushalmodi, is there a reason you did not include `pointer` type?
16:22:17FromDiscord<Gary M> I'll have to run some benchmarks again to sure, but I know at the very least that debug builds without either opt:speed or lto, (can't remember which caused it to perform proper inlining) can give you such extremely abysmal performance even for debug builds because of it.
16:22:28FromDiscord<treeform> kaushalmodi, should adding p + 1 (move p by 4 byte) if p is ptr[uint32] ?
16:22:45FromDiscord<Gary M> Beef suggested it was an issue with my specific environment that the `--opt:speed` flag wasn't on by default
16:22:56FromGitter<kaushalmodi> treeform: ⏎ ⏎ > is there a reason you did not include pointer type? ⏎ ⏎ No, I didn't need it so far [https://gitter.im/nim-lang/Nim?at=60c0eae019b46c60b179f286]
16:23:04FromDiscord<treeform> I feel like p + 1 should move it by 1 byte, and p[1] should do the 4 byte thing?
16:23:07FromDiscord<treeform> thoughts?
16:23:14*nixnet08 quit (Client Quit)
16:23:51FromGitter<kaushalmodi> > I feel like p + 1 should move it by 1 byte, and p[1] should do the 4 byte thing? ⏎ ⏎ that would need one to remember to think which is which. The current is consistent
16:24:02FromGitter<kaushalmodi> You can do byte extraction by mask anding?
16:25:05*Len[m]2 left #nim (#nim)
16:25:31FromGitter<kaushalmodi> May be you can have p + 1 move by a byte by first casting to byte ptr type?
16:25:33FromDiscord<treeform> I feel like there are pros and cons here. The p + 1 moves by 1 byte makes pointers feel more C like, number like. While p + 1 moves by 4 makes it more consistent hmm...
16:26:11FromDiscord<Gary M> I thought C style pointer arith was `p + 1 = p + sizeof(T) + 1`
16:26:23FromDiscord<Gary M> not p + 1 byte
16:26:37FromDiscord<Gary M> (edit) "+" => ""
16:26:58FromGitter<kaushalmodi> treeform, Gary M: issues and PR's are welcome. I have started documenting on https://github.com/kaushalmodi/ptr_math/issues
16:27:04FromGitter<kaushalmodi> Need to sign off now, thanks
16:27:11FromDiscord<treeform> bye
16:27:25FromDiscord<Gary M> > Incrementing a pointer increases the stored address by the size of its type.
16:27:38FromDiscord<Gary M> so incrementing by a single byte would be non-standard if anything?

16:56:38planetis[m]guys I need opinions, my in place init functions look like `initMyType`. Is it better if I shorten them to just `init`? The nep1 doc doesn't mention anything about it.
16:56:46FromDiscord<Rika> no
16:56:50FromDiscord<Rika> oh, in place?
16:58:32FromDiscord<Rika> i would

17:29:44planetis[m]i am used to initMyType being the one recomended (i think i read it in Nim in action) but in this case I think just `init` is better
17:31:04planetis[m]There is init in sets. `var s: HashSet; init s`
17:32:34planetis[m]however locks chose the long names `initLock L` and I am building on Locks...
17:33:22planetis[m]yeah I am totally nitpicking. I will leave it as is and do something better :)

17:48:16FromGitter<kaushalmodi> heh, nvm from me too.. I just looked at your "does float != float64" message
17:48:32FromGitter<kaushalmodi> turns out you were assigning an array to a float
17:48:51FromDiscord<Alea> I can't see a float equivalent to IntArray
17:48:56FromDiscord<Alea> so not sure how to define it
17:49:30FromGitter<kaushalmodi> > I can't see a float equivalent to IntArray ⏎ ⏎ What do you mean? What's an IntArray?

17:50:04FromDiscord<Alea> but I just noticed that that's a custom type

18:10:32FromDiscord<haxscramper> In reply to @reversem3 "what should I be": you want to compare files for equality and then pattern match (I assume by parsing content)?

18:16:36FromDiscord<haxscramper> The code is not mine - someone in the telegram chat asked a similar question, so I basically just copied relevant part
18:17:12FromDiscord<haxscramper> Though they mentioned this solution is slower compared to even python, so more optimized version (for example that does not read whole file at once via `readAll()`) can be used
18:17:52FromDiscord<haxscramper> There is also a https://nim-lang.org/docs/sha1.html#secureHashFile%2Cstring which might be better suited for computing file hashes
18:17:57reversem3<FromDiscord "<haxscramper> In reply to @rever"> No I mean kind of what grep can do , by comparing the lines in a file to another file then writing out to screen. I want to take a file and compare the strings in the file and find a match in a directory of thousands of files.
18:18:45reversem3does that make sense?
18:19:15FromDiscord<haxscramper> Just read file and compare lies to a pattern? `for file in walkDir(...): for line in lines(file): if line == pattern`
18:19:47FromDiscord<haxscramper> It would be slow as optimized versions like `rg/grep` use clever heuristics to speed things up
18:19:49reversem3ok so os/walkDir is that it
18:20:15reversem3yeah that is true

18:42:03FromDiscord<treeform> Well usually when I deal with pointers its because my data is mixed types.
