00:02:41FromDiscord<millymox> In reply to @elegantbeef "`let result = result.strip`": says it still cant open for me
00:02:42FromDiscord<millymox> hm
00:03:11FromDiscord<millymox> sent a code paste, see https://play.nim-lang.org/#ix=4yMP
00:03:24FromDiscord<millymox> might just use external python code
00:03:29FromDiscord<millymox> use tkinter for now
00:04:01FromDiscord<elegantbeef> Jesus
00:04:46FromDiscord<elegantbeef> Yea that code works fine for me, are you sure you're not getting spurious characters?
00:05:12FromDiscord<elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=4yMQ
00:06:12FromDiscord<elegantbeef> Given that you're using zenity I'd suggest owlkettle
00:06:21FromDiscord<elegantbeef> It's a nice declarative Nim gui that does have a file dialog
00:06:41FromDiscord<elegantbeef> Though there is https://github.com/Patitotective/tinydialogs/tree/main
00:30:04FromDiscord<millymox> In reply to @elegantbeef "Yea that code works": interesting, im on macos, perhaps thats the issue?
00:35:04FromDiscord<elegantbeef> Perhaps
00:35:05FromDiscord<millymox> In reply to @elegantbeef "Yea that code works": the file has spaces in it, thats about it
00:35:09FromDiscord<millymox> shouldn't be an issue though
00:35:38FromDiscord<elegantbeef> You could do `echo result.toOpenArrayByte(0, result.len)`
00:35:46FromDiscord<elegantbeef> then ensure there are no odd characters
00:37:04FromDiscord<elegantbeef> `result.high`
00:37:44FromDiscord<millymox> still doesn't work
00:37:44FromDiscord<millymox> hm
00:38:01FromDiscord<elegantbeef> Well it's not going to make it work it's to ensure there are no wrong characters
00:38:14FromDiscord<elegantbeef> Well it's going to show you if there are no wrong characters
00:38:26FromDiscord<millymox> ah well yeah, even extrenal python code doens't work. Is there something wrong with open() on macos?
00:38:34FromDiscord<elegantbeef> Perhaps
00:38:35FromDiscord<millymox> i can't even open a txt called hey.txt
00:38:38FromDiscord<millymox> no spaces
00:38:52FromDiscord<elegantbeef> Perhaps it's a locale issue? I don't really know
00:39:12FromDiscord<elegantbeef> Do you not have permissions for the file you're attempting to open?
00:39:28FromDiscord<millymox> i should have permissions, its in download folder, perhaps try sudo?
00:41:35FromDiscord<millymox> escalating perms to sudo does not work
00:42:35FromDiscord<elegantbeef> so does `zenity` return an incorrect string?
00:42:43FromDiscord<elegantbeef> Might have some non printed characters
00:43:04FromDiscord<elegantbeef> oh wait you said you just did `open("test.txt")`?
00:43:44FromDiscord<millymox> hey.txt. It seems to be maybe an issue weith directory paths?? cuz i can do it if its in my directory bhut anything outside its a no
00:44:26FromDiscord<elegantbeef> This sounds a lot like some permission issue, but given you used sudo it's quite odd
00:44:49FromDiscord<millymox> yes i did sudo ./main
01:04:23FromDiscord<millymox> how to go about threacding in nim?
01:24:04FromDiscord<michaelb.eth> In reply to @millymox "how to go about": it depends on what you're trying to do, can be a pain-point with Nim
01:25:18FromDiscord<michaelb.eth> if you look back through the `#internals` channel on this discord you'll see there's been a lot of discussion in recent weeks+
01:25:29FromDiscord<michaelb.eth> related to multi-threading, I mean

02:00:31FromDiscord<huantian> You might consider using async instead of threading if your task is io bound like http requests
02:00:34FromDiscord<elegantbeef> You don't return anything i read proxies
02:00:49FromDiscord<millymox> In reply to @huantian "You might consider using": example?
02:01:12FromDiscord<elegantbeef> implicit result
02:01:13FromDiscord<elegantbeef> sent a code paste, see https://paste.rs/FfIAg
02:01:21FromDiscord<elegantbeef> That's a much more idiomatic version and closes teh file handle

02:01:59FromDiscord<michaelb.eth> 🙀 even
02:02:07FromDiscord<elegantbeef> Yea people that don't work at status use them
02:02:15FromDiscord<michaelb.eth> anyway, mummy might be worth a look: https://github.com/guzba/mummy
02:02:22FromDiscord<michaelb.eth> for @millymox I mean
02:03:18FromDiscord<millymox> In reply to @michaelb.eth "anyway, mummy might be": can i send requests with it
02:03:21FromDiscord<millymox> or just routes?
02:03:58FromDiscord<michaelb.eth> I'm not sure, haven't used it myself, I just recall that the author had/has a focus on making it work well re: how threading works in Nim
02:05:06FromDiscord<millymox> In reply to @michaelb.eth "I'm not sure, haven't": ask far as i can see its just a library for handeling req, like backend stuff
02:05:10FromDiscord<millymox> ill take a look at the code though
02:05:17FromDiscord<elegantbeef> It's for backend
02:05:20FromDiscord<michaelb.eth> you want proxy middleware, that kind of thing?
02:05:37FromDiscord<michaelb.eth> ah yeah, duh, I see proxy in your code above
02:05:53FromDiscord<millymox> i just want a http library that isn't the standard library that supports proxies
02:06:23FromDiscord<elegantbeef> Why not the stdlib?
02:06:57FromDiscord<millymox> In reply to @elegantbeef "Nim has an implicit": Thank you but how do i return the proxies so i can use them?
02:09:08FromDiscord<millymox> its okay got it
02:10:50FromDiscord<elegantbeef> What do you mean how do you return them, it r eturns them
02:11:38FromDiscord<millymox> its why i said its okay i was being stupid
02:16:34FromDiscord<millymox> In reply to @elegantbeef "Why not the stdlib?": nothing im just in a shit mood lmao
02:16:49FromDiscord<millymox> Im loving nim so far though

02:40:58FromDiscord<millymox> i get the same error: Bad file descriptor
02:42:00FromDiscord<elegantbeef> Also you're using threads for no reason, this is an async problem
02:42:19FromDiscord<elegantbeef> How many proxies do you have, could be hiting a file descriptor limit
02:42:43FromDiscord<millymox> In reply to @elegantbeef "How many proxies do": 11k proxies
02:42:49FromDiscord<millymox> 11,000
02:47:50FromDiscord<elegantbeef> Yea you likely need to do fewer at once
02:50:39FromDiscord<michaelb.eth> I'd suggest trying it with chronos on a single thread
02:50:54FromDiscord<elegantbeef> any async solution 😄
02:50:59FromDiscord<elegantbeef> or CPS
02:51:09FromDiscord<michaelb.eth> the event loop may get bottled up, but you won't know until you try
02:51:18FromDiscord<michaelb.eth> (edit) "bottled" => "backed"
02:51:25FromDiscord<elegantbeef> I assume you'd still need to chunk it
02:51:30FromDiscord<millymox> In reply to @michaelb.eth "I'd suggest trying it": link?
02:51:34FromDiscord<huantian> Make like a queue system
02:51:35FromDiscord<millymox> to chrons
02:51:37FromDiscord<elegantbeef> 11k requests + async is likely to eat descriptions
02:51:39FromDiscord<millymox> chronoes
02:51:46FromDiscord<huantian> Or do what did and use callbacks in a omega jank way
02:52:10FromDiscord<michaelb.eth> https://github.com/status-im/nim-chronos↵you want apps/httpclient↵https://github.com/status-im/nim-chronos/tree/master/chronos/apps/http

02:53:16FromDiscord<michaelb.eth> just note that chronos event loop and std/asyncdispatch event loop can't run in the same thread, i.e. don't try to mix and match chronos stuff with std/asyncdispatch stuff
02:53:53FromDiscord<millymox> okay thank you
02:55:07FromDiscord<huantian> Is there a reason to use chronos over stdlib async client
02:55:16FromDiscord<elegantbeef> Not really unless you care about cycles
02:55:21FromDiscord<elegantbeef> It also uses bearssl
02:55:25FromDiscord<elegantbeef> chronos that is
02:55:43FromDiscord<elegantbeef> Statically linked makes it easy to ship on winblows
02:55:54FromDiscord<michaelb.eth> In reply to @huantian "Is there a reason": well, chronos is being used in production at scale with a lot of $$ on the line, can the same be said of std/asyncdispatch?
02:56:17FromDiscord<elegantbeef> That's a pointless argument for "why"
02:56:23FromDiscord<michaelb.eth> not that that proves anything, just that it's an indicator that it's solid if it's being used correctly

09:07:30*oldpcuser_ quit (Ping timeout: 240 seconds)
09:33:31FromDiscord<fabricio> so I'm still a bit confused about the copying semantics in Nim for strings and seqs. if I pass a string/seq to a function as a value but I don't mutate it inside the function, will thedata be duplicated and a new string/seq will be created to be passed, or same data will the be reused
09:41:08FromDiscord<graveflo> looks like it doesn't copy when I try it
09:53:38PMunchfabricio, Nim is smart enough to know that if you pass a seq to a procedure which isn't allowed to mutate it it will be safe to do so by pointer. So under the hood it passes a pointer in

10:24:17FromDiscord<heysokam> 1.6.12
10:24:28FromDiscord<intellj_gamer> oh weird,↵You could download this file and put it there https://github.com/nim-lang/Nim/blob/devel/tools/debug/nim-gdb.py

10:53:59FromDiscord<heysokam> is there a better way to debug nim code than this?↵i cannot even find the variables i need to search for 😔
11:08:42FromDiscord<demotomohiro> In reply to @heysokam "well, maybe not. i": Did you ru nim-gdb or load nim-gdb.py with `source Nim/tools/debug/nim-gdb.py`?
11:09:01FromDiscord<heysokam> nim-gdb
11:09:41FromDiscord<heysokam> seems like the nim-gdb binary was in my system, but not the script
11:11:35FromDiscord<demotomohiro> If you set a value to a variable but didn't use it, Nim might remove that variable and you cannot find it on debugger.
11:12:11FromDiscord<heysokam> i tried with `break myfile.nim:num` and it didnt' find the file
11:12:34FromDiscord<heysokam> didn't even try setting a variable name, since i don't know exactly the variable name im looking for (or else i wouldn't need the debugger)
11:13:00FromDiscord<heysokam> usually, in C, i step through it close enough so that i can find where im going or how to stop it close enough
11:13:21FromDiscord<heysokam> but here i cannot find anything, because its all mangled 😦↵thought that the nim-gdb thing would help with that
11:13:34FromDiscord<odexine> Did you compile with debugger symbiks
11:13:37FromDiscord<odexine> Symbols
11:13:40FromDiscord<heysokam> of course
11:13:48FromDiscord<odexine> How did you do so exactly
11:13:51FromDiscord<demotomohiro> `--debugger:native`
11:14:12FromDiscord<heysokam> i believe i had that by default, but let me recheck in case i didn't
11:14:30FromDiscord<odexine> Nim doesn’t do that by default so I assume you mean you put it in a config file
11:14:45FromDiscord<heysokam> yeah i do it in my config
11:14:56FromDiscord<heysokam> it was commented out though ⚰️
11:17:19FromDiscord<heysokam> oh i can see the code now! ty, that was me being a dummy 🙏
11:45:20FromDiscord<fabricio> In reply to @PMunch "<@607600292086939696>, Nim is smart": okay but what if a function takes a large object as param by value that doesn't get mutated and I have a ref or a ptr to one of those objects. if I dereference that ptr/ref so I can pass it as a value to the function, will the compiler be smart enough to not do the deref and pass the ptr/ref directly under the hood
11:46:32PMunchThat's an interesting question, but I believe it should still pass that by reference (a pointer)
12:05:47FromDiscord<demotomohiro> In reply to @fabricio "okay but what if": If you care that, you can read generated C code in Nim cache directory.
12:06:10FromDiscord<jmgomez> Also `bycopy` and `byref` exists
12:16:04FromDiscord<fabricio> In reply to @jmgomez "Also `bycopy` and `byref`": oh cool didn't know that thanks
12:22:07FromDiscord<demotomohiro> sent a code paste, see https://play.nim-lang.org/#ix=4yOP
12:23:54FromDiscord<jmgomez> demo, if you do `exportc` it will be easier to follow as it doesnt mangle
12:23:59FromDiscord<demotomohiro> You don't need to use `bycopy` or `byref` pragma unless you are calling C/C++ functions.↵Nim passes arguments optimal way and you don't need to optimize them yourself.
12:28:20FromDiscord<demotomohiro> sent a code paste, see https://play.nim-lang.org/#ix=4yOR
12:29:28FromDiscord<demotomohiro> Anyway, there is no code that copy `BigObj`.
12:33:27FromDiscord<jmgomez> The type can also have it 😛
12:34:19FromDiscord<jmgomez> Yeah, IIRC `array[24, byte]` would be copied but `array[25, byte]` wouldnt
12:34:27FromDiscord<jmgomez> (in most platforms)
12:34:52PMunchThe magic size is 3*sizeof(float) IIRC
12:35:00FromDiscord<jmgomez> exactly
12:51:46PMunchHmm, I'm getting false for fileExists on files that definitely exists
12:53:21FromDiscord<demotomohiro> Maybe it doesn't have permission to access the file or parent directly?
12:53:52PMunchAh, never mind..
12:54:13PMunchI was pulling stuff from environment variables, and I had set them as strings in quotes..

16:33:42FromDiscord<odexine> postContent 3rd argument is of type `string` so just put the json as a string, i am not sure what library you are using for json
16:34:33FromDiscord<millymox> In reply to @odexine "postContent 3rd argument is": i am not using a library for json i didn't know i needed one, completely new to this so i apologize for my ignorance
16:35:19FromDiscord<millymox> what library do you reccomend?
16:35:21FromDiscord<odexine> well some need one some dont, if you just want to simply send the json "{"api_key": "key"}" as is without needing to manipulate it you can always manually construct the string like this↵`"{\"api_key\": \"key\"}"`
16:36:01FromDiscord<odexine> you will want to set the headers `client.headers = newHttpHeaders({ "Content-Type": "application/json" })`
16:36:10FromDiscord<odexine> before sending the post
16:36:30FromDiscord<millymox> Thank you so much okay i got it!
16:38:45FromDiscord<millymox> In reply to @odexine "well some need one": {"balance":4.7868,"errorId":0,"errorCode":null,"errorDescription":null}↵↵how would i go about parsing the balance of this response?
16:39:00FromDiscord<odexine> okay so this is where the json library comes in
16:39:11FromDiscord<millymox> okay okay what do you suggest
16:39:18FromDiscord<odexine> https://nim-lang.org/docs/json.html is the basic standard library json library
16:39:28FromDiscord<odexine> there are others but i think for now you should start with this
16:39:39FromDiscord<odexine> see the docs for more information
16:39:46FromDiscord<odexine> it shouldnt be too difficult
16:41:24FromDiscord<millymox> awesome thank you taking a look right now

16:44:40FromDiscord<odexine> what are you trying to do?
16:44:45FromDiscord<odexine> like what is it you want to do
16:44:55FromDiscord<millymox> get the "balance" and assign it to a variable and echo it
16:45:11FromDiscord<millymox> get the value of the key balance and assign it to the balance variable and then echo balance
16:46:34FromDiscord<odexine> `let balance = jsonNode["balance"]` doesnt have the echo part, and this gives you a json node (you have to convert it to the appropriate primitive type like integer or string)
16:47:17FromDiscord<odexine> with the conversion `let balance = jsonNode["balance"].getFloat`
16:48:38FromDiscord<millymox> In reply to @odexine "with the conversion `let": Thank you this works, i appreciate the help

16:52:26FromDiscord<millymox> In reply to @michaelb.eth "there's also jsony: https://github.com/treeform/jso": Okay great thank you, i have to ask: who is treeform? I see a lot of things made by him, is this a company, or person or?

17:31:46FromDiscord<voidwalker> because I don't understand why it's lowercase in the request itself : `user-agent:`

23:35:41FromDiscord<Elegantbeef> I prefer using matrix but at times the bridge dies
23:36:37FromDiscord<jviega> I mean, the whole point of async is to let the async system resume your func easily where you left off when there's something to do. Explicitly waiting around for it isn't sensical if you're using async

23:37:05FromDiscord<millymox> In reply to @Elegantbeef "I prefer using matrix": Ahhh okay i see
23:37:24FromDiscord<jviega> I don't like async, but then you should have a different model where you're polling to read w/ epoll and then dispatching to a handler
23:39:39FromDiscord<jviega> Basically, if you've got thousands of file descriptors because you're handling a lot of connections, idle threads wait for any descriptor to fire, and then go handle that. It scales far, far better than async and tends to be far less error prone / (easier to understand the control flow and debug) in the systems I've seen.
23:40:26FromDiscord<millymox> In reply to @jviega "Basically, if you've got": Ahhhh okay i see i understand
23:40:28FromDiscord<millymox> thank you
23:40:32FromDiscord<Elegantbeef> Eh they're mostly just moving through a list of proxies afaik, so there isnt much reason not to just use async 😄
23:41:11FromDiscord<Elegantbeef> Like yes you can just use selectors or similar, but for most cases async will be fine for this code

23:49:11FromDiscord<Elegantbeef> You could also do full on generic code and just define procedures that do the parts that are different
23:49:49FromDiscord<Elegantbeef> That way you can make a basic interface and implement segments per type
23:51:26FromDiscord<millymox> Ahhh perhaps, some captchas differ largely from other, this method would work for recaptcha and hcaptcha but GeeTest and cloudflare turnstile are very different
23:52:26FromDiscord<millymox> So basically just have a generic create_task function, or join_task function and then have segements depending on the client
23:52:58FromDiscord<Elegantbeef> Operations can be their own procedures and then you could implement those procedures per types
