00:09:57FromDiscord<brainproxy> sent a long message, see http://ix.io/2su6
00:10:56Yardanicoyou shouldn't need any specific configuration for that
00:11:11Yardanicovscode-nim will provide suggestions automatically for .nim files you open
00:11:28Yardanicoif there's no autocompletion, check that nimsuggest is in your PATH and the plugin actually can find it
00:16:38*rockcavera quit (Remote host closed the connection)
00:18:04FromDiscord<brainproxy> nimsuggest is availble in PATH, just checked↵↵In e.g. `src/foo.nim` I `import nimcrypto` where nimcrypto is installed in `vendor/nimcrypto`. When `src/foo.nim` is opened in vscode I get a warning: `cannot open file: nimcrypto` and there are warnings/errors re: undeclared identifiers for procs, etc. in nimcrypto
00:18:21Yardanicoand how do you compile?
00:18:36Yardanicoyou need to have proper configuration so nimsuggest works
00:18:49Yardanicoe.g. if you specify --project on cmdline - you need to do that in the config file
00:18:50FromDiscord<brainproxy> a custom makefile system
00:18:52Yardanicosame for include, import, etc
00:19:05FromDiscord<brainproxy> I wouldn't compile using vscode, just from command-line
00:19:11Yardanicoyes, and how do you compile?
00:19:18Yardanicowhat command switches do you provide to nim?
00:19:25FromDiscord<brainproxy> https://github.com/status-im/nimbus-build-system/
00:19:41FromDiscord<brainproxy> that injects a lot of stuff into the environment related to nim compiler params
00:19:53FromDiscord<brainproxy> and then you write make targets taking advantage of that
00:20:17Yardanicowell you have to know how it actually manages the special nim compiler params
00:20:23Yardanicoand replicate then in the .cfg (or .nims) file
00:20:31Yardanicoto actually get nimsuggest to understand where stuff comes from
00:20:51Yardaniconimsuggest uses the compiler, so you need to make same config files as you would do for the compiler itself
00:20:53FromDiscord<brainproxy> fair enough
00:21:03FromDiscord<brainproxy> thanks for the tip!
00:21:22FromDiscord<brainproxy> will ask the nimbus folks if any of them have done that for their local vs code setup
00:21:29FromDiscord<brainproxy> (if any of them use vs code)
00:22:20Yardanico well it doesn't matter if it's vscode or not
00:22:36Yardanicoyou need to do that for any editor supporting nimsuggest (or nimlsp which uses nimsuggest)
00:22:38FromGitter<bung87> just setting compiler flags through config files
00:22:43Yardanicoyes, as I said
00:22:56FromDiscord<brainproxy> ah right, sure
00:23:06FromDiscord<brainproxy> (edit) '(if' => '~~(if' | 'code)' => 'code)~~'

00:26:07*FromDiscord joined #nim
00:28:16FromGitter<bung87> "backend" could be a valid switch? that extension may concerns
00:28:35YardanicoI think status mostly uses the C backend :)
00:31:53FromGitter<bung87> have known extension that aware of backend settings? I havnt know
00:31:57Yardanico??
00:32:05YardanicoI'm sorry, I don't understand :)
00:32:48FromGitter<bung87> I mean extension use some file detecting backend settings
00:32:57Yardanicoit doesn't really
00:33:00Yardanicothat's done by nimsuggest
00:33:51FromDiscord<Varriount> Yaaaaaardanico. Such a fun name to say.
00:33:54FromGitter<bung87> then provider editor features for that backend
00:34:03Yardanicoi still don't understand :P
00:34:20Yardaniconimsuggest have "backend-specific" commands
00:34:25Yardanicodoesn't have*
00:35:32FromDiscord<Varriount> shashlick: I'm having trouble getting Nimterop to work with config files. when I pass a mixture of command-line arguments and a config file to toast, it exits with non-zero exit code, but doesn't print any error messages.
00:36:30FromGitter<bung87> ok, that's fine. basically i just use c backend

06:39:04FromDiscord<slymilano> a "linter" for Nim so to speak.
06:40:03FromDiscord<Rika> code style only afaik
06:40:11FromDiscord<Rika> i mean, appearance
06:40:28FromDiscord<Rika> nimpretty for appearance of code
06:40:39FromDiscord<Rika> nothing for analysis, i dont think
06:41:02leorizenarimiran: can you update the hash for fusion in Nim?
06:41:29narimiranleorize: oh, there's a hash? so that's why it is still failing? :)
06:41:39leorizeyep :P
06:41:47FromDiscord<slymilano> thanks Rika
06:42:12FromDiscord<Yardanico> @slymilano well there's nim check
06:42:29FromDiscord<Yardanico> It'll report all warnings and hints just like the compiler
06:42:32FromDiscord<Yardanico> Without compiling
06:42:43FromDiscord<Rika> oh yeah that
06:43:38FromDiscord<Elegant Beef> Considering your dont write idiomatic nim code anyway slymilano what's that code smell 😄
06:49:10FromDiscord<Yardanico> Damn I actually didn't think about that, although I already made my own way of single line procs https://forum.nim-lang.org/t/6607

08:36:28Yardanicowell yes it might crash
08:36:32Yardaniconimsuggest has crashes
08:36:37Yardanicoand nimlsp uses nimsuggest
08:36:54Yardanicofor a good bug report you should try to minimize the source code file which created this crash :)
08:37:04Yardanicoso it doesn't depend on any imports at all, and roughly <100 loc :P
08:37:20FromDiscord<kodkuce> ye, so to do that would need what
08:37:26FromDiscord<kodkuce> to delete half code
08:42:34Yardanicoadded two more examples to https://github.com/nim-lang/Nim/wiki/Nim-features-you-didn't-know-you-needed XD
08:43:17Yardanicofeel free to add if you have any
08:43:24Yardanicojust some unusual, less-known nim features
08:43:41Yardanicois named argument overloading documented by the way?
08:43:49FromDiscord<Clyybber> nope, should add that
08:43:52YardanicoXD
08:44:03FromDiscord<Clyybber> it doesn't have tests too
08:44:13Yardanicobut it works :P
08:44:19FromDiscord<Clyybber> but nimgame2 tests it :p
08:45:35narimiranYardanico: oh, range type exampes! i had no idea that worked! :)
08:45:43Yardaniconeither did I really
08:45:53Yardanicofound it on some github project which had "port: 1 .. 65535" in object field definition
08:46:04superbia1when is walrus operator coming to nim
08:46:11Yardanicosuperbia1: you can implement it yourself
08:46:15Yardanicowith a single line template
08:46:29Yardanicosee https://github.com/Yardanico/nimpylib/blob/master/src/pylib.nim#L177
08:46:53Yardanicoalthough it behaves a bit differently
08:47:28superbia1yea
08:47:54Yardanicobut for most cases it can work the same as the python walrus
08:47:59Yardanicobut I don't think we'll get that as a built-in :)
08:48:07Yardanicobecause as I showed it's trivial to implement with a template
08:51:37narimiranif anybody has some extra time, can you do a sanity check for me? clone https://github.com/nim-lang/fusion and try to run `nim doc src/fusion/htmlparser/xmltree.nim`
08:51:44Yardanicosure
08:51:58Yardanicofails
08:52:07narimiranon my end, it behaves differently than the stdlib version
08:52:09Yardanicoat the <firstTag> thing
08:52:13narimiranyep
08:52:15Yardaniconarimiran: well yeah I think it has some changes
08:52:26narimiranyeah, it does have, i'm now comparing

08:56:08Yardanicoignore them for now

09:31:05FromDiscord<Clyybber> Araq: We either need to attach scopes to gensymmed symbols, or put gensymmed symbols actually in the scope (I mean they still can't be accessed normally)
09:31:15FromDiscord<Clyybber> Because otherwise gensymmed forward decls can't work
09:31:44*nerthus left #nim ("Leaving")
09:31:54Araqas I said
09:32:12AraqI'd rather see the effort spend on eliminating forward decls
09:32:40Araqthen you still cannot gensym forward decls but nobody cares as forward decls are not required anymore
09:32:51FromDiscord<Clyybber> Yeah
09:32:52Araqin fact, comparing proc signatures is unsound
09:33:06FromDiscord<Clyybber> why?
09:33:14Araqbecause of default values
09:33:26FromDiscord<Clyybber> hmm
09:33:35Araqthey can be arbitrary 'static' expressions
09:33:54FromDiscord<Clyybber> yeah
09:33:58Araqwhich you have to evaluate before you can compare them. ok, maybe it's not unsound
09:34:01Araqbut it's bad
09:34:08FromDiscord<Clyybber> bad yeah, but not wrong :p
09:34:39FromDiscord<Clyybber> in general though, is there something that would make it a bad idea to put gensymmed symbols in the scope?
09:34:50FromDiscord<Clyybber> I mean they have the `gensym suffix anyways
09:34:55FromDiscord<Clyybber> so you can't access them
09:35:31Araqmaybe it won't hurt
09:35:44Araqbut I'm not sure
09:36:07FromDiscord<Clyybber> ok, I'll try and see if the CIs spout anything at me
09:38:52FromDiscord<Clyybber> Araq: Kinda related, should we add a test for name based overloading?
09:39:01FromGitter<bung87> narimiran I see the commit, I might add more test for that , it's really intend to check if single tag
09:39:09FromDiscord<Clyybber> Its used in the wild already (nimgame2) and we don't have a test for it yet
09:39:22Araqhuh I remember writing a test for it
09:39:25narimiran@bung87 it already worked okay, from what i can tell
09:39:29Araqdid you check tests/overload ?
09:39:43narimiranand with your changes, lots of runnable examples were failing
09:40:36FromDiscord<Clyybber> Araq: Ah, I missed it

09:50:50FromDiscord<Clyybber> I mean it won't prevent you from collisions will it?
09:51:34FromDiscord<mratsim> I'm okay with a 2^64 space
09:51:48FromDiscord<mratsim> with the birthday paradox it's 2^-32 chance of collision
09:52:30FromDiscord<mratsim> If I have a collision it's probably when the lightning strikes me as I win the loto

10:05:32*hoijui joined #nim
10:05:44FromDiscord<mratsim> Laser is more of a research repo, before productionizing stuff. I wasn't the one to add it to nimble
10:06:45FromDiscord<mratsim> for CPU compat, separate the various SMID support in different files so that you can use different {.localPassC:"-mavx".} or {.localPassC:"-mavx2".} flags
10:07:48FromDiscord<mratsim> Not sure exaclty what you want to provide but if you want to go fast the easiest would be to wrap SLEEF. THough I know some routines are slower than what I did in Laser (for example exponentiation)
10:08:02FromDiscord<mratsim> https://sleef.org/
10:08:14FromDiscord<lqdev> makes sense, but for distributing binaries, should i stick to a particular extension?
10:09:13FromDiscord<mratsim> SSE2 is implied for x86-64.
10:09:54FromDiscord<mratsim> otherwise, people using it would likely use runtime CPU detection
10:10:12FromDiscord<mratsim> but runtime CPU detection only makes sense at the algorithm level
10:10:55FromDiscord<mratsim> you don't choose at runtime the implementation of "add" the overhead would be to big, but you do that at the matrix addition level
10:11:15FromDiscord<lqdev> i see
10:11:27*hoijui quit (Ping timeout: 260 seconds)
10:11:36FromDiscord<lqdev> so calling procs from variables is slower than calling them directly?
10:11:59FromDiscord<mratsim> I don't get what you mean
10:13:11FromDiscord<lqdev> well, i'd implement that runtine CPU detection to use a few variables which store the procs, and then call the procs stored in those variables in the public interface
10:14:10FromDiscord<mratsim> what I mean is, count 1 cycle for an "if branch", and 1 cycle for vector addition, whether on 4 elements (SSE) or 8 elements (AVX).↵↵If you want to add 8 elements, you test for SSE or AVX + proces you get 3 or 2 cycles↵If you always use SSE you get 2 cycles.
10:16:08FromDiscord<mratsim> What you want to do is called function multiversioning
10:16:35FromDiscord<mratsim> But you only want to do that at a higher level as well
10:18:05FromDiscord<mratsim> a function in a variable cannot be inlined, this means pushing and poping registers before the function call.↵But when you want SIMD you are usually in an algorithm that needs to get the data as fast as possible in the proper memory locationto benefits from SIMD.↵Moving data around (due to function call) will likely be a problem.
10:18:23FromDiscord<lqdev> alright
10:18:34FromDiscord<lqdev> didn't consider inlining
10:18:49FromDiscord<lqdev> thanks for the advice!

10:22:34*abm joined #nim
10:23:13FromDiscord<mratsim> If you want to do more SIMD, my advice is to find an algorithm you want to implement and optimize (could be numerical computing, could be graphics). Implement it in plain Nim, and then start moving parts to SIMD
10:23:49FromDiscord<Clyybber> Zevv: You should be able to change the T: untyped to T: type at least
10:24:03FromDiscord<mratsim> There are some in laser/benchmarks (fp_reduction_latency / exponentiation) but there are plenty of other stuff like color conversion for example
10:24:16FromDiscord<mratsim> what about T: typedesc?
10:24:35FromDiscord<Clyybber> its the same
10:24:42FromDiscord<mratsim> Akshually*
10:24:43FromDiscord<Clyybber> but type is fancier
10:24:49FromDiscord<Clyybber> no akshually
10:24:55FromDiscord<Clyybber> that bug has long been fixed :D

10:25:41FromDiscord<Clyybber> but there may be some other unreported ones

10:32:39FromDiscord<Clyybber> bung87: Regarding the unittest issue, maybe the best way to fix this is to make check raise a custom UnitTestCheckFailedException or something like that

10:38:48FromDiscord<kodkuce> oh dumb question rith, constants are know at compile time right? for this i should use let

10:57:19FromDiscord<mratsim> I'm subscribed to many many Status lib but plenty other libs I want to keep track of and somehow Github doesn't highlight PR on your own libraries :/
10:57:45FromDiscord<mratsim> The worse is Github Actions that spams notifications
10:58:26FromDiscord<Clyybber> bung87: try except
10:58:41FromDiscord<dom96> GitHub notifications are terrible
10:59:15FromDiscord<Vindaar> I always just check on the LHS of the notification screen whether there's new activity in any of my repos
11:00:30FromDiscord<Vindaar> I guess if one is subscribed to more than 30 or so active repos even that doesn't really work well though, since those might not even be on the first page?
11:01:54FromGitter<bung87> that's users try except, I mean top level check raise UnitTestCheckFailedException how that would be handled

11:10:10narimirannature: use neovim, there's a great nim plugin for it
11:10:26narimiranhttps://github.com/alaviss/nim.nvim
11:11:07naturethx, is autocompletion available ?
11:11:13narimiranit is
11:11:31natureI am using coc.vim when I dev in js, python etc...
11:12:27nature narimiran ooooh I already had that repo open in my browser :)
11:13:07natureAre you using it ? Cause I also found this: https://github.com/PMunch/nimlsp but I am not familiar with LSP
11:13:09narimirannature: btw, you can ping the author of the plugin here, he goes by the name: leorize
11:13:53narimiranyes, i'm using nim.nvim together with asyncomplete, and it works great for me
11:14:09narimirani've never used coc.vim, so i cannot comment on that
11:14:44narimiranand i never used any of the LSP stuff, so no help there from me either, sorry
11:15:03naturecoc.vim brings the vscode autocomplete, plugins etc.. in Vim, pretty nice but I sometimes feel in might be bloated ^^'
11:16:04naturenarimiran: And what do you think of https://github.com/zah/nim.vim ?

15:33:23FromDiscord<ProperFellow> Hi there! New to Nim, and playing around with making a performant CRUD (using Prologue). I want to make db queries async using a connection pool, but I'm having a hell of a time finding documentation (or being sure I'm using the right packages). I've looked at Gatabase. Am I looking in the right spot?
15:33:50disruptekthere are simple db connectors in the stdlib.
15:33:52disruptekwhich database?
15:34:52Zevv[m]are these async tho
15:36:08disruptekjuancarlospaco's gatabase is async?
15:36:26Zevv[m]I have no clue. I don't database
15:37:08disrupteki don't see `async` on the README.
15:38:18Zevv[m]disruptek: I love your exceptions but I hate them
15:38:33disrupteki know.
15:38:50disrupteki know you would rather impl exceptions using continuations.
15:39:00Zevv[m]nah, it's not about that
15:39:05Zevv[m]but now you always put that stuff in
15:39:22disruptekyeah, they can be gated.
15:39:36Zevv[m]cna we put them in as a transformation of a try: catch: in the original?
15:39:41Zevv[m]or doesn't that map
15:40:36Zevv[m]but man, you're on a roll
15:40:58disruptekthey can be remapped, but if you catch inside your continuation, i'm not sure you're doing it right.
15:41:19Zevv[m]yeah I see. But now I have no choice
15:41:27disruptekthe idea is that we give you a semantic that doesn't exist otherwise. it's lives in the dark place between the trampoline and the runtime.
15:41:32Zevv[m]why can't I just catch in my trampoline?
15:41:45disruptekthat's what cpsTrace does.
15:42:10Zevv[m]but my default transformation now is full of 'excepts' in each proc
15:42:19disruptektrue.
15:42:34disruptekbut it re-raises them, right?
15:42:46Zevv[m]yeah but you're forcing this in
15:42:59disruptektrue, but it should be very efficient under arc.
15:43:04Zevv[m]I want my cps iterator to run as fast as nim closure iterators
15:43:08disruptekbut again, we can gate it.
15:43:23Zevv[m]what do you solve by catching it here instead of just letting it go?
15:43:24disruptekit can be a pragma on the cps proc.
15:43:42disruptekthe idea is that continuations can continue and collect errors.
15:43:58disruptekalso you can change the behavior on the exit.
15:44:13Zevv[m]hm ok, Im starting to see
15:44:26Zevv[m]but I'm not sure if this should be default behaviour
15:44:36disruptekbut again, we can gate it.
15:44:41Zevv[m]right
15:47:17disruptek`let x = yield foo()` can be a thing. it seems explicit and yield will be useless outside iterators, which we are useless inside.
15:47:27disruptekso it kinda works out.
15:48:02disruptekalso, it kinda says "magic control flow here."
15:48:30Zevv[m]fair enough.
15:48:57FromDiscord<ProperFellow> Sorry catching up. Using postgres. The db connectors in stdlib are not async. Gatabase offers pooling - and seems to offer async according to one of the meme images. There's no real documentation.
15:49:11FromDiscord<Rika> gatabase is very new
15:49:13Zevv[m]The other thing I ran into yesterday - I'd like to have some data around during my traversal over the continuations. But where would I store such a thing. Is that in #26 as well?
15:49:18disruptekjc is pretty active, though, so you won't have trouble getting support.
15:49:23Zevv[m]I guess there is becasue you put your exceptions somewhere
15:49:54FromDiscord<ProperFellow> So reach out to jc directly?
15:50:11disruptekyou could create an issue; i think he'd like to hear from you.
15:50:24disruptekZevv[m]: you can store it in local scope like anything else, right?
15:50:45Zevv[m]no, it's not for the cps functions, it's for the evq/pump implementation
15:51:01disruptekwhat are we talking about?
15:51:09disrupteki store "stack frames" in the trampoline.
15:51:16FromDiscord<ProperFellow> Will do 🙂
15:51:34Zevv[m]disruptek: yeah, but that's internal to the cps/environment coed
15:51:36FromDiscord<ProperFellow> Building anything db related is admirable stuff 🙂
15:51:38disruptekjc probably has a good handle on the domain.
15:52:03disruptekZevv[m]: how do you figure?
15:52:31FromDiscord<ProperFellow> Actually nailing this down could lead to a better techempower benchmarks showing - the nim frameworks currently don't show up in anything db related.
15:52:57Zevv[m]disruptek: get back to you later, the familiy is hangry
15:53:01disruptekkk
15:58:24FromDiscord<dom96> ProperFellow: getting a highly performant async db implementation to win these benchmark will not be easy 🙂
15:58:30FromDiscord<dom96> (edit) 'benchmark' => 'benchmarks'

16:14:52FromDiscord<lqdev> without the need for external tools to analyze my code for me.
16:15:21FromDiscord<lqdev> it also has AST-based macros, which can greatly simplify boilerplate-heavy code.
16:20:00FromGitter<Lecale> I like your answer disruptek
16:20:28FromDiscord<mratsim> you can't do multithreading in Python 😛
16:20:43FromDiscord<lqdev> well you can
16:20:47FromDiscord<lqdev> but the GIL slows everything down
16:20:58FromDiscord<mratsim> you can do multiprocessing but not multithreading
16:21:40FromDiscord<mratsim> but as Python, Nim, C are all turing complete, they are all equivalent to an imaginary tape
16:22:04FromDiscord<mratsim> the differenc eis how easy to achieve your goal (safety, speed, time to market, hiring, maintenance)
16:22:59FromDiscord<mratsim> Nim scores well on Safety, speed, maitnenance, very low on hiring, and time-to-market is a mixed bag (depends on the library ecosystem)
16:23:51FromDiscord<mratsim> Python scores well on Time to market and Hiring, but scores bad on the rest
16:24:49FromDiscord<mratsim> C on speed, hiring, mixed bag on maintenance, safety and time to market is the same as Nim probably
16:25:04FromDiscord<mratsim> and you can create your own goals as well
16:29:03*Vladar joined #nim
16:32:41FromDiscord<Varriount> @lqdev Multithreading in Python is only useful if you're doing IO or using C extensions.
16:33:52FromDiscord<ProperFellow> sent a code paste, see https://play.nim-lang.org/#ix=2sxc
16:33:52FromDiscord<Varriount> IO routines (which are implemented in C) can release the GIL while waiting for IO to complete. Same with some C extensions.
16:34:08FromDiscord<ProperFellow> (edit) 'https://play.nim-lang.org/#ix=2sxc' => 'https://play.nim-lang.org/#ix=2sxd'
16:34:21FromDiscord<ProperFellow> Looks like the nim compiler is crashing because there's a global variable in jester?
16:35:01FromDiscord<Varriount> @ProperFellow What does your code look like? Sounds like something was passed to a Jester macro that the macro didn't understand.
16:35:25FromDiscord<ProperFellow> sent a code paste, see https://play.nim-lang.org/#ix=2sxe
16:36:01FromDiscord<ProperFellow> Maybe I shouldn't be using the DSL?
16:37:31FromDiscord<Varriount> Hm, what happens if you put the code in /tasks into a procedure, and call it instead?
16:40:50Zevv[m]so disruptek
16:40:56Zevv[m]with all this untypdness
16:41:19Zevv[m]do you see during .cps. if a call goes to something with a pragma?
16:41:48disruptekwhat?
16:41:50Zevv[m]ie can you distiguish a normal call vs a cps call vs a cpsPrim call with only the ident getting called?
16:42:00disrupteki doubt it.
16:42:24FromDiscord<lqdev> so you guys want to turn untyped to typed?
16:42:24Zevv[m]yeah thats what I was afraid of. too bad that is
16:42:25FromDiscord<lqdev> prepare to summon demons in the process
16:42:32Zevv[m]we just summon mratsim

16:43:51FromDiscord<ProperFellow> That did it.
16:44:17FromDiscord<ProperFellow> I wonder why DSL's are such a thing in the first place - noticed them in other spots for Nim.
16:44:18disruptekZevv[m]: you have to be able to `let x: int = yield foo()` when `proc foo(): string`. this is what we're achieving...
16:44:27FromDiscord<lqdev> not sure what your specifics are, but the way *I* turn untyped to typed is from the first macro i return a call to another macro that takes typed as its params instead
16:44:46Zevv[m]disruptek: so where does the return value of yield come from
16:44:47disruptekyeah, this is a thing. but we're hoping to not go there.
16:45:00FromDiscord<lqdev> then prepare to write your own type checker.
16:45:06Zevv[m]because foo returns a string and you get x: int
16:45:14disruptekno, i don't need types anymore.
16:45:15Zevv[m]if this is going to be the quality of your work
16:45:25Zevv[m]where we're going we don't need types!
16:47:13disruptekthe problem right now is that we are pass-by-copy for symbols in the env and we would need to rewrite the symbols to make them pass-by-ref.
16:47:28disruptekrror: attempt to redefine: 'a5'
16:48:12*endragor quit (Ping timeout: 265 seconds)
16:49:03FromGitter<alehander92> guys i realized i need to just not redefine classes in my `.cpp`
16:49:14FromGitter<alehander92> i havent even gotten to cmake problems!
16:49:31FromGitter<alehander92> nim no headers :(
16:49:49FromDiscord<lqdev> headers are such a pita when working with C/C++
16:50:32FromDiscord<ProperFellow> ``` let rows = await getAllRows(db, sql"SELECT * FROM tasks ORDER BY priority asc", @[])↵ var results: seq[TodoTask] = @[]↵ for row in rows:↵ results.add(TodoTask(id: parseInt(row[0]), text: row[1], priority: parseInt(row[2])))```
16:50:36FromDiscord<ProperFellow> I think I'm doing this wrong.
16:50:42FromDiscord<ProperFellow> It's complaining row[0] is a char.
16:51:03FromDiscord<ProperFellow> But it should be getting rows of [int, string, int].
16:51:17FromDiscord<ProperFellow> Is there something like "dir" in python to inspect what's coming back with rows?
16:51:44Zevv[m]so how do I run this 'deep' of yours. Now I get call to undeclared `ex0=` when running my minimal stuff
16:51:47FromDiscord<Rika> Can't you just echo the type of row
16:51:57disruptekZevv[m]: do a pull, for kickoffs.
16:52:07Zevv[m]done
16:52:18disruptekthe problem right now is that we are pass-by-copy for symbols in the env and we would need to rewrite the symbols to make them pass-by-ref.
16:52:28Zevv[m]right
16:52:30disruptekat least, that's my working theory.
16:52:43disruptekthat a5 clashes with a5 although they are both gensym'd.
16:52:55Zevv[m]just as I described in #27
16:55:47Zevv[m]that sounds like the other problem I made this workaround for
16:56:05Zevv[m]37f0063262cdc173f13a6b4871e410343a4dc775
16:57:50FromDiscord<Kiloneie> Oh man making a video on Objects is quite a deal xD... comparison to tuples, inheritances, pointers lol...
16:58:29Zevv[m]well, what about skipping all that for part 1
16:58:37Zevv[m]just concentrate on the basics
16:58:50FromDiscord<Kiloneie> might split it on part 1 and 2...
16:58:52Zevv[m]you can probably spend a whole video on inhertance
16:58:54*superbia2 joined #nim
16:59:00Zevv[m]and pointers are not special for objects,
16:59:22FromDiscord<Kiloneie> yeh but accessing values of reference objects is a pointer thing.
16:59:36disrupteknah.
17:01:18FromDiscord<Kiloneie> Im thinking part 1 is Pointers and Objects(normal little objects and comparison to tuples, why and how), then part 2 is referencing/inheritance
17:01:25*superbia1 quit (Ping timeout: 256 seconds)
17:01:25FromDiscord<IanIAnIAN> Just copy every regurgitated argument ever made on Medium and put them in intersecting loops until the viewers head explodes like in Scanner (or they go do something else)
17:01:36FromDiscord<Rika> You can have a pointer to a primitive though?
17:02:02FromDiscord<Kiloneie> ehm oO
17:03:40Zevv[m]disruptek: how is that nah. you have clashes while they are gensymed
17:03:43Zevv[m]that was exactly my problem
17:03:56Zevv[m]im pretty sure this can be the same thing
17:04:08disrupteki was talking about obj rerefs. 😉
17:04:30FromDiscord<Rika> reref?
17:04:36disruptekderef
17:07:18FromDiscord<Kiloneie> Derail
17:10:27FromDiscord<Kiloneie> Everytime im "finally got objects covered, now just record the video", i find more stuff it connects to and needs explaining... im not making 3 parts for this... 2 is more than enough D:...
17:13:53FromDiscord<Kiloneie> Pretty sure it's gonna be easier to make a video on Macros than this. Templates especially, so easy.
17:16:28Zevv[m]what is your always-working-reference program for cps disruptek, because I'm not sure how to use this now in 'deep'
17:16:43disruptekthat would be a nice feature, huh?
17:16:54Zevv[m]it would
17:17:10Zevv[m]I don't even understand how to bootstrap my initial cps call now
17:17:23disruptekto make it work we need a fn() that we generate for each continuation type.
17:17:32Zevv[m]right
17:17:46disruptekelse the trampoline doesn't know how to work.
17:17:55Zevv[m]for the initial call from the normal world into the abyss called CPS
17:18:30Zevv[m]the first step through the looking glass
17:18:31FromDiscord<lqdev> @Kiloneie trust me, *no*
17:19:05FromDiscord<Kiloneie> Okay sure D:... still Templates are easy though :P.
17:19:14disruptekyou should probably merge your {.cps: Cont.} thing and i'll rebase.
17:19:19FromDiscord<lqdev> templates yeah
17:19:20FromDiscord<lqdev> macros no
17:19:28Zevv[m]disruptek: cmin up
17:19:37disrupteki need to make some calls and stuff and then i will put in fn().
17:19:42FromDiscord<ProperFellow> How do you unwrap a future in Nim?
17:19:45Zevv[m]merged
17:20:13FromDiscord<lqdev> @ProperFellow either `waitFor` or `await`
17:20:17FromDiscord<lqdev> depends on the context
17:20:20FromDiscord<ProperFellow> Hmmm
17:20:21Zevv[m]disruptek: sure you're not taking too big steps
17:20:31Zevv[m]you're doing five things in one go
17:20:32FromDiscord<lqdev> you use `waitFor` outside of async procs, and `await` in async procs
17:20:48FromDiscord<ProperFellow> Using await still isn't quite working for me.
17:20:56Zevv[m]leave all that exception handling out for now, for example
17:21:04FromDiscord<ProperFellow> ``` let rows: seq[Row] = await getAllRows(db, sql"SELECT * FROM tasks ORDER BY priority asc", @[])↵ var results: seq[TodoTask] = @[]↵ for row in rows:↵ results.add(TodoTask(id: parseInt(row[0]), text: row[1], priority: parseInt(row[2])))```
17:21:11disruptekit's already behind --define:cpsExcept
17:21:12FromDiscord<ProperFellow> It's erroring out
17:21:24Zevv[m]ok, so now we just focus on moving one block of memory around
17:21:31FromDiscord<ProperFellow> ```~/.nimble/pkgs/jester-0.4.3/jester.nim(551, 13) Error: type mismatch: got <FutureBase, int literal(0), CallbackAction>↵```
17:21:33Zevv[m]your current brute-force approach is fine for now I guess
17:21:39Zevv[m]my proposal is just optimization
17:22:19*maier joined #nim
17:22:34Zevv[m]I hope you appreciate my approach of making minimal, viable use cases of different things built on CPS, instead of going in async IO with bells and whistles up to my elbow
17:22:44disrupteki do.
17:22:52Zevv[m]cool
17:23:14disruptekit's starting to be more interesting as we expand what we're capable of.
17:23:21Zevv[m]right
17:23:22disrupteki don't care about web-servers anymore. 😉
17:23:27Zevv[m]but I need some hooks to hang stuff
17:23:35disruptekthere are many more hooks now.
17:23:41disrupteknamed continue, for example.
17:23:44Zevv[m]for example, my silly 'goto' - I need a place to store these 'jump labels'
17:23:50Zevv[m]no I need to make them global
17:24:11disruptekyou can `punch`.
17:24:17Zevv[m]you're not inventing your own control flow inside transformad cps procs, are you
17:24:18Zevv[m]don't you dare
17:24:25disruptekwhy not?
17:24:28Zevv[m]please don't go there yet
17:24:33Zevv[m]just translate nim
17:24:34Zevv[m]not nim++
17:24:47Zevv[m]it confuses the hell out of everbody except you
17:25:18Zevv[m]I know you are so tempted
17:25:21Zevv[m]but you must resist
17:25:30Zevv[m]you must learn to use these powers first
17:25:35Zevv[m]you must be strong
17:25:46Zevv[m]just sit on you friggin hands and type
17:25:53disruptekkinky.
17:26:34Zevv[m]how must anyone learn how this stuff works if what you type inside a cps proc is no longer nim?
17:26:55disruptekthese are extensions. that's what nim is all about.
17:27:01Zevv[m]too soon
17:27:18disruptekthere's nothing creepy going on here (yet).

17:31:57FromDiscord<Clyybber> hi

17:59:42disruptekoh, hmm.
17:59:52Zevv[m]instead of making 'var i = env_ths(locals_that).i`
17:59:58disruptekseems kinda reasonable.
17:59:59Zevv[m]it does `template i = env_ths(locals_that).i`

18:00:36Zevv[m]let nim do the work for you
18:00:43disruptekyeah, we'll try it.
18:01:02Zevv[m]My 'with' macro was once complicated like that, then PMunch came along and did just that
18:01:14Zevv[m]and I felt kind of stupid for not thinking of it

18:03:24disrupteki don't care.
18:03:57Zevv[m]only downside is that the 'repr' of the translated proc now looks like shit because nim adds tons of whitespace and newlines around nnkTemplDefs

19:31:22FromDiscord<Clyybber> one where you still have to write foo(it: MyIter): MyIter {.cpsRaw}
19:31:34Zevvstep away for a sec
19:31:36disruptekyou can do that now.
19:31:57disruptekfoo(it: Cont) {.cps: Cont.} means the same thing.
19:32:25disruptekit just lets you access `it` from inside the continuation, anywhere.
19:32:32ZevvThere's a number of different things happening. I might make another little writeup because makin the other one today helped me think. But we have
19:32:43Zevv1) the initial call/instantation from nim to the first cps
19:33:02Zevvthat one returns something magic that you can send to a trampoline or an event queue
19:33:13Zevvthis should be simple and user friendly and hide shit
19:33:14Zevvright?
19:33:30disruptekwell, it's a little more subtle.
19:33:46Zevvso I want to make an interator instance. I want to do makeCounter(0, 10)
19:33:47disruptekyou want a way to deref the result of that continuation, which we're calling `yield foo()`.
19:34:07disruptekand we want a way to NOT deref it, which i think is `continue foo()`.
19:34:30disruptekyou can of course do things like `spawn foo()`.
19:34:36disruptekor whatever primitive you want.
19:34:49Zevvyeah but you keep thinking in terms of your frigging eventqueue
19:34:51Zevvburn that
19:35:08disruptekfine, but `continue` still needs to be a thing.
19:35:12FromDiscord<Clyybber> when we start to use continue X we may never make it a typed macro
19:35:14disruptekbecause `discard` is a thing.
19:35:15Zevvwhat is 'continute'
19:35:29disruptekcontinue is a single bounce on the trampoline.
19:35:30Zevv'continue'. What is it. where does it live, waht does it eat and what does it poop
19:35:39disruptekit's in cps context only.
19:35:42ZevvOk, I don't want CPS to make 'continue'
19:35:49ZevvYour continue is not my continue
19:35:55FromDiscord<Clyybber> what actually is preventing us from making it typed?
19:35:58FromDiscord<Clyybber> the arg
19:36:32Zevvor maybe only if continue is no more then a template doing `a = a.fn(a)`
19:36:37Zevvbecause that's all continue is
19:36:38Zevvright
19:36:39Zevv?
19:37:11disrupteki think so.
19:37:39ZevvOk, we have 2 kinds of "users". The end user does not want to know *any* of this shit. They want to do async io or iterators, and not be bothered
19:37:46Zevvthe other users are the people implementing stuff with CPS
19:37:52Zevvthey need to know the details, and have power
19:38:06Zevvthey are smart enough to bounce that thing
19:38:23Zevvso for user #1 we need to be able to hide all the gory details.
19:38:44Zevvbut for user #2, the people who implement .cpsMagic. things, we need to provide hooks and mechanics
19:39:20Zevvso .cps. procs hide everything. The look like a normal proc, and might have hidden stuff going in or out.
19:39:36Zevvthe .cpsMagic. procs are explicit, and I think they should totally honest about what is going in and out
19:39:40Zevvbecause you want to touch that stuff
19:39:55Zevvif you are implementing your event queue or whatever
19:40:20Zevvdoes that make any sense?
19:40:21FromGitter<alehander92> `next`
19:40:23FromGitter<alehander92> make it next
19:40:26FromGitter<alehander92> like next tick
19:41:01FromGitter<alehander92> like ruby, they call `continue` `next`
19:41:08Zevvlook at my little iterator: https://github.com/disruptek/cps/blob/master/stash/iterator.nim
19:41:22ZevvThe 'end user' stuff is at the bottom. You make an iterator like 'var i = counter(3, 7)'
19:41:25Zevvi is your iterator
19:41:27Zevvno special stuff whatsoever
19:41:56Zevvjust one simple plain honest nim function call
19:42:24Zevvthat function signature matches the one of the `proc counter(...)` which is a .cps. proc
19:42:28Zevvthat is pretty great
19:42:32Zevvno surprises there
19:49:18disrupteksurprise, ICE
19:49:30Zevvbaby

19:50:17FromDiscord<Clyybber> disruptek: tell me abotu the ICE
19:50:24FromDiscord<Clyybber> is it "proc still forwarded"?
19:51:44disruptekaieee all my vars look like templates.
19:52:11FromDiscord<Clyybber> I *need* to know your ICE

19:53:09FromDiscord<Clyybber> ahlrigt
19:53:09natureIs there a builtin ternery operator in nim ?
19:53:14FromDiscord<Clyybber> nope
19:53:24FromDiscord<Clyybber> we have if expressions though
19:53:30disrupteklet x = if foo: 1 else: 2
19:53:50natureokok that's what I was looking for, thaks :)
19:53:53naturethanks
19:54:03*theelous3 joined #nim
19:54:37disruptekcps has while: else: expressions.
19:56:34natureis something like `let x = (if foo: 's' else: '') & 'tring'` legal ?
19:57:00natureor is there a better way to do it ?
19:57:39disruptekwe use " to delimit strings.
19:58:39natureoh yes... I am still new to Nim sorry.
19:58:55FromDiscord<Clyybber> other than that its legal yes

20:23:19FromDiscord<ProperFellow> I'm trying to read an image and write it to a file. In Python it's super simple, I grab the content (string) and just write it out to the file using `wb`. Kind of lost on how to do this using nim's standard lib.
20:23:58disruptekhttps://nim-by-example.github.io/files/
20:24:39FromDiscord<ProperFellow> That just covered text files.
20:24:51disruptekis there a difference?
20:25:04FromDiscord<ProperFellow> Between a binary file and text files?
20:25:05FromDiscord<ProperFellow> Yes.
20:25:12disruptekwhat is it?
20:25:18FromDiscord<ProperFellow> I can see if treating it as a string will work. Perhaps Nim glosses over that.
20:25:55FromDiscord<lqdev> it's a little bit dodgy but you can cast a string to a `seq[uint8]` as their binary representations are nearly identical
20:26:14FromDiscord<lqdev> the only difference is that strings have a NUL terminator
20:26:30FromDiscord<ProperFellow> Hmmmm
20:26:54FromDiscord<lqdev> well, to be safe you can always just copy the memory over to a new seq.
20:27:20FromDiscord<lqdev> ```nim↵var theSeq: seq[uint8]↵copyMem(theSeq[0].addr, yourString[0].unsafeAddr, yourString.len)↵```
20:27:24FromDiscord<lqdev> ah whoops
20:27:27Zevvdisruptek: they do for me
20:27:30Zevvwhats the problem
20:27:37FromDiscord<lqdev> it has to be `var theSeq = newSeq[uint8](yourString.len)`
20:27:44FromDiscord<lqdev> otherwise it'll write out of bounds
20:29:14FromDiscord<ProperFellow> Yeah getting out of bounds now (Error: unhandled exception: index -1 not in 0 .. 4 [IndexError]) - not the clearest error - sysFatal.
20:29:16Zevvif its broken revert it, it was ment to go in a branch but i messed that up
20:30:01FromDiscord<lqdev> @ProperFellow look at the stacktrace, it should tell you more about where the error happened
20:30:36disruptekthe problem is with the new env.
20:31:15Zevvoh but that was not there when i made that, so its not my fault not my fault
20:31:28Zevvplausibe deniability

20:33:33FromDiscord<ProperFellow> Ah I'm trying to get the last element of an array.
20:33:42FromDiscord<ProperFellow> I don't see documentation on how to find it hahahaha.
20:35:11FromDiscord<lqdev> you use `BackwardsIndex`. you can create one using `^`, eg. `mySeq[^1]` gets the last elemtn
20:35:14FromDiscord<lqdev> (edit) 'elemtn' => 'element'
20:35:18FromDiscord<ProperFellow> Ah!
20:35:23FromDiscord<ProperFellow> Is this documented anywhere?

20:36:08FromDiscord<aachh> i was about to send this
20:36:08FromDiscord<aachh> you were faster :(
20:36:52FromDiscord<ProperFellow> Nice - that all works.
20:37:06FromDiscord<ProperFellow> Ah gotcha.
20:37:06FromDiscord<lqdev> @ProperFellow Nim uses a separate type for this to not have to burden the runtime with checking negative indices. the compiler does the work of resolving a separate overload of `[]`
20:37:24FromDiscord<ProperFellow> That's impressive.
20:37:39FromDiscord<ProperFellow> I'm really enjoying Nim - but the documentation doesn't feel super newbie friendly.
20:37:46FromDiscord<lqdev> yeah it could use a bit of work
20:37:46FromDiscord<aachh> for me it actually feels really nice
20:37:47FromDiscord<aachh> xD
20:37:49FromDiscord<ProperFellow> As far as navigating around - or helpful examples.
20:38:01FromDiscord<aachh> i think im the only person that likes it
