00:02:27FromDiscord<aintea> Another day I woke up knowing Nim could be 5 times better if it has proper sum types and good pattern matching on sum types.↵↵There are libraries that provide macros for pattern matching but oh boy when there's an error just restart the whole project over again
00:03:57FromDiscord<aintea> I have seen a GitHub issue open about this and sum types that could be implemented as well as the desired syntax↵↵Do you guys see any way sum types could be not implemented by choice ?↵Or am I just a bad programmer wanting sum types where I should be using something else ?
00:07:07FromDiscord<Robyn [She/Her]> In reply to @aintea "I have seen a": Sum types actually have an RFC and are supposed to be Eventually™️ be implemented, I believe
00:08:10FromDiscord<Elegantbeef> Sum types are just object variants but with a more concise syntax and type system
00:08:25FromDiscord<Elegantbeef> So you're not a bad developer just someone that wants some sugar
00:38:10FromDiscord<auxym> Tried to install Nim on my work PC yesterday. Got caught by Windows Defender, which caused IT to immediately get a notificatiton and block me from accessing anything on the network. Also had me immediately bring in my laptop to be re-imaged, "just in case".↵↵I'm aware of the whole false positive situation and I understand the Nim team's position. But the whole situation is quite unfortunate. Now I'll have to code the thing I wanted in C
01:14:37FromDiscord<threefour> Holy moly
01:16:00FromDiscord<threefour> I'm glad my employer isn't so overbearing
01:19:45FromDiscord<auxym> it's a university, used to be pretty chill, then they got a few scares / close call security incidents in the past year or two. Now everything is locked down and security, security, security. Security first, get work done second.
01:20:18FromDiscord<Elegantbeef> Maybe they should use linux instead of windows

06:20:15FromDiscord<ayex> sent a long message, see https://pasty.ee/ZSDLTlOB
06:30:01FromDiscord<emmuni> In reply to @k0ts "does compiling Nim from": yes because the issue stems from windows freaking out when something is compiled using gcc so if you compile stuff with clang or msvc it should be fine
06:30:38FromDiscord<emmuni> choosenim also prevented the false positive from the standard windows installer for me if i recall correctly
06:30:49FromDiscord<emmuni> so perhaps that's a easy solution
06:31:50FromDiscord<zumi.dxy> are legitimate malware written in nim that common?? 💀
06:32:03FromDiscord<emmuni> no
06:32:06FromDiscord<emmuni> that's not the issue at all
06:32:09FromDiscord<emmuni> read what i said
06:32:49FromDiscord<zumi.dxy> so it's an issue with all gcc/mingw binaries?
06:33:29FromDiscord<emmuni> not all, some code compiled using gcc even if not malicious gets flagged by windows, it has been an issue for ages on windows, i've never looked into why
06:34:11FromDiscord<emmuni> then again, even if you compile a binary in C++ for example, using any compiler, as soon as you read/write to virtual memory windows also flags that
06:34:52FromDiscord<angelsdust> I remember back during win 7/xp era compiling any `"\n"` with mingw/gcc would trigger windows defender lol
06:35:21FromDiscord<spotlightkid> The whole thing is part of an educational program by the free software foundation to teach Windows users by practical example why proprietary operating systems are bad.

06:39:42FromDiscord<emmuni> In reply to @angelsdust "I remember back during": at least windows defender went from being totally useless in windows 7 and actually being useful in windows 10/11 albeit it flags a lot of false positives
06:42:33FromDiscord<ayex> very interesting - I have to try that with some of my formerly flagged nim code. 🤔↵(@emmuni)
06:46:42FromDiscord<emmuni> In reply to @ayex "very interesting - I": you can probably google mingw gcc false positive and get results that are the same problem but in C/C++ so the issue does not stem from Nim itself in any way

07:31:19FromDiscord<pmunch> Where do you work, the NSA or something?
07:31:31FromDiscord<pmunch> Maybe you could fire up a VM to do Nim coding in
07:34:04FromDiscord<pmunch> And yeah, if the problem was as easy as "compile with clang instead of gcc" then it would be very easy to work around
07:43:41*ntat quit (Quit: Leaving)
08:12:52FromDiscord<nnsee> In reply to @pmunch "Maybe you could fire": as an alternative, ssh + sshfs works nicely
08:13:17FromDiscord<nnsee> i'm not sure how well supported sshfs is on windows, though
08:14:04FromDiscord<ringabout> I use WSL2+vscode, it's very smooth
08:35:31FromDiscord<pmunch> In reply to @nnsee "as an alternative, ssh": sshfs?
08:35:38FromDiscord<odexine> ssh file system via fuse
08:35:49FromDiscord<odexine> https://github.com/libfuse/sshfs
09:02:48PMunchAh right
09:03:07PMunchSo everything is hosted externally and only mounted localy
09:03:17PMunchBut if it is fuse then it won't run on Windows will it?
09:03:31PMunchAnd if you're running Linux this is a moot point

09:42:08FromDiscord<nnsee> i thought maybe windows would have fuse support... but perhaps not
09:44:30FromDiscord<odexine> i was under the impression that wsl is fuse capable
09:44:51FromDiscord<nnsee> oh, that probably does

14:36:15FromDiscord<angelsdust> Does nim support multiple returns?
14:36:30FromDiscord<k0ts> there is no types-inside-types
14:37:41FromDiscord<demotomohiro> In reply to @angelsdust "Does nim support multiple": You can use a tuple to return multiple values.
14:38:13FromDiscord<angelsdust> In reply to @demotomohiro "You can use a": Can I do sth like `var a,b,c = "a_b_c".split("_")`?
14:38:41FromDiscord<k0ts> no because the number of elements is not known at compile time
14:38:46FromDiscord<k0ts> you can do something like that with strscans though

15:33:12FromDiscord<odexine> What do you mean write it shorter?
15:33:40FromDiscord<odexine> There are functions in the sugar module that would help shorten that yes
15:41:41*ntat joined #nim
15:47:33FromDiscord<angelsdust> Like lambdas
15:50:04FromDiscord<demotomohiro> `proc(foo: var FOO) = foo.Bar()` is not a lambda?
15:51:52FromDiscord<odexine> Anonymous function and lambdas are commonly conflated
15:57:06FromDiscord<angelsdust> I meant it as, is there a short hand notation for lambas/anonymous functions like `(foo) -> foo.bar`

16:21:48FromDiscord<emmuni> In reply to @auxym "Installing via choosenim was": oh, perhaps i already added it as an exception then
17:14:25FromDiscord<michaelb.eth> In reply to @odexine "Anonymous function and lambdas": are they not the same thing, generally speaking ?↵↵maybe you have in mind a difference that’s contextual, like a specific language where the terms mean slightly different things?
17:16:42FromDiscord<michaelb.eth> wikipedia redirects “Lambda function (computer programming)” to “Anonymous function”

20:45:24FromDiscord<luteva> Hi! I would like to have a "field pragma" to genrate some code, just like the bitsize pragma:↵https://nim-lang.org/docs/manual.html#implementation-specific-pragmas-bitsize-pragma↵how can I do this? Any Example? (I do not want to explicitly call a macro after the type declaration.)
20:46:16FromDiscord<Elegantbeef> codegendecl is the closest you can get
20:46:21FromDiscord<Elegantbeef> Otherwise you need a typesection macro
20:47:43FromDiscord<luteva> is there any example of how to implement this?
20:49:19FromDiscord<Elegantbeef> What are you trying to do though?
20:51:53FromDiscord<luteva> sent a code paste, see https://play.nim-lang.org/#pasty=xYbSHdLM
20:52:34FromDiscord<Elegantbeef> So you do not need code gen?
20:52:51FromDiscord<luteva> but i see codegendecl seems to be too specific for something else 😉
20:52:57FromDiscord<Elegantbeef> you can use a user defined pragma then detect it later using `std/macros`
20:53:24FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#pasty=SimrpLeN
20:53:33FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#pasty=JKNXhpGN
20:54:19FromDiscord<Elegantbeef> the sunny package also uses the pragma pragma to some effect
20:55:53FromDiscord<Elegantbeef> As does https://github.com/beef331/dodger/blob/master/dodger/protocol/queries.nim
20:56:05FromDiscord<Elegantbeef> Though in your case I'd just implement procs over the pragma
20:56:18FromDiscord<luteva> but pragma pragma afaik has to be called later in the code right?↵I just don't want to call it. It should all be done by the pragma declaration.
20:56:34FromDiscord<Elegantbeef> Call what?
20:56:37FromDiscord<Elegantbeef> You're tagging afaict
20:56:37FromDiscord<luteva> but thx anyway. i'll have a look at the repo!
20:56:39FromDiscord<Elegantbeef> Why do you need to call
20:57:32FromDiscord<luteva> oh yes you can detect it, right? yes that may work for me.
20:57:38FromDiscord<luteva> thx! 💯
21:08:02FromDiscord<luteva> sent a code paste, see https://play.nim-lang.org/#pasty=mSaFDYse
21:08:33FromDiscord<Elegantbeef> What does `hasMany` actually do though?
21:09:49FromDiscord<luteva> generate some procs like User.add(post) which adds posts to the list of posts etc. and for deletion etc.
21:10:15FromDiscord<luteva> just like thi: https://guides.rubyonrails.org/association_basics.html#has-many
21:10:39FromDiscord<Elegantbeef> Where would it add them to though?
21:11:39FromDiscord<Elegantbeef> Like write the code you want to automate
21:11:43FromDiscord<luteva> to that module for the type User i think/hope 😄
21:13:54FromDiscord<luteva> sent a code paste, see https://play.nim-lang.org/#pasty=RTGwkneg
21:15:45FromDiscord<luteva> so user.add(comment) is just shorthand for user.comments.add(comment)
21:18:36FromDiscord<luteva> so if the has_many macro is being detected, it should add a seq[Comment] field to the type and add some procs to easily fill and clear this field. later, it should also handle the db references (like setting the foreign keys etc.)
21:19:06FromDiscord<luteva> that's just what ActiveRecord do.

21:51:10FromDiscord<luteva> ok first of all: thanks a lot!↵So, just to chack if i understood correctly:↵What you do is: write the "add"-proc and in that proc you check, if the proc is valid, by checking if the filed has the desired progma, right?
21:51:24FromDiscord<luteva> (edit) "chack" => "check"
21:51:42FromDiscord<Elegantbeef> You find where to add by iterating an objects fields and detecting the pragma
