04:23:58FromDiscord<Yardanico> deleted again :(
04:48:38FromDiscord<Elegantbeef> Who's deleting these?
05:08:25FromDiscord<deadmeme77> Is Nim on termux outdated?
05:08:38FromDiscord<Elegantbeef> Probably
05:09:58FromDiscord<demotomohiro> Package manager on termux installed nim-1.6.6 on my android phone.
05:10:49FromDiscord<deadmeme77> It's 1.6.6 in mine too. Not too shabby
05:11:29FromDiscord<deadmeme77> Enough for some quick demo I'd say
05:11:39FromDiscord<Elegantbeef> That's stable
05:11:42FromDiscord<Elegantbeef> So yes that's up to date
05:12:45FromDiscord<demotomohiro> As far as I know, package manager on gentoo and arch linux provides nim-1.6.6 now.
05:19:04FromDiscord<deadmeme77> It runs perfectly. Nice 👍
05:24:25FromDiscord<deadmeme77> @demotomohiro have you been using Nim to script batch jobs in your phone? If so, do you need root for Termux to be able to find files in Android's SD cards?
05:44:25FromDiscord<demotomohiro> I just use Nim to test some code on termux.
05:46:09FromDiscord<demotomohiro> @deadmeme77 It seems you can read sdcard from termux: https://wiki.termux.com/wiki/Internal_and_external_storage
06:04:20FromDiscord<Prestige> Elegantbeef are you familiar with testing frameworks that can "mock" function calls? I've been thinking of implementing this for my Nim testing framework but am not sure it's possible, without compiler access...
06:05:08FromDiscord<Elegantbeef> I doubt you need compiler access
06:05:46FromDiscord<Prestige> I can describe the functionality if you are unfamiliar
06:06:03FromDiscord<Elegantbeef> I'm unfamiliar so go ahead but yea i doubt you need compiler access
06:06:56FromDiscord<Prestige> "mocking" a function allows you to substitute the body of the function, basically. Change what it does and what it returns. The tricky part, I think, is substituting this for the whole Nim program
06:07:19FromDiscord<Rika> Just import some other module that mocks the function?
06:07:20FromDiscord<Elegantbeef> Yea that's what i figured you might have IO/Capi and at test time want to only return X thing
06:07:33FromDiscord<Elegantbeef> Yea that's less complex than my idea
06:07:48FromDiscord<Elegantbeef> My idea would be replace a call with your own function using a macro
06:07:52FromDiscord<Rika> Oh wait hm I get it
06:07:57FromDiscord<Prestige> In reply to @Rika "Just import some other": How could you do that globally for your program?
06:07:58FromDiscord<Rika> No I get it wait
06:08:48FromDiscord<Rika> You prolly “have” to put a define flag
06:08:51FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=40s7
06:08:51FromDiscord<Rika> Yeah that
06:08:57FromDiscord<Rika> Wait I got a warning brb
06:09:20FromDiscord<Prestige> hmmm
06:10:01FromDiscord<Prestige> Elegantbeef is there some neat way you could have the testing framwork search all files that would be used, see if it has said import, then replace it with that?
06:10:04FromDiscord<Prestige> Or am I overthinking this
06:10:29FromDiscord<Elegantbeef> I mean just make that your module
06:10:41FromDiscord<Elegantbeef> There is no reason for fancy shit
06:10:52FromDiscord<Prestige> Because I don't want anything related to testing to actually imported into files unrelated to testing, basically
06:11:02FromDiscord<Prestige> I want to keep all testing logic within the test
06:11:28FromDiscord<Elegantbeef> put a `when not defined(test): {.error: "you imported test in non test environment".}` inside `mymoduletest`
06:11:37FromDiscord<Elegantbeef> I dont see that you really need any magic here
06:11:45FromDiscord<Elegantbeef> But you know me i'm often wrong
06:12:09FromDiscord<Prestige> I could write like an example of what I want to be writing in a test I guess, if that would help
06:13:00FromDiscord<Elegantbeef> You can also emit your own procedures/calls if you really wanted
06:13:22FromDiscord<Elegantbeef> But that requires macros which dont make this reasonable to look at imo
06:14:17FromDiscord<Prestige> perhaps
06:15:13FromDiscord<Prestige> in my test I want to be able to just do like, `mock(module.someProc, myImpl)` and when I compile and run the test, it calls `myImpl` instead of `module.someProc`
06:15:25FromDiscord<Prestige> Then I don't need to create other files, etc
06:15:43FromDiscord<Elegantbeef> Sure but that requires replacing all `someProc` usage without the information where
06:15:51FromDiscord<Prestige> Yeah
06:15:58FromDiscord<Elegantbeef> So that surely needs compiler support
06:16:27FromDiscord<Elegantbeef> But you could do something like `mock(someProcCall(args), myProcToReplace, myReplacementProc)`
06:17:10FromDiscord<Elegantbeef> You might be able to abuse term rewriting macros
06:17:53FromDiscord<Prestige> hm
06:17:57FromDiscord<Prestige> I'd like more info on that
06:20:51FromDiscord<Prestige> this would be really powerful for testing
06:21:10FromDiscord<Elegantbeef> Writing an example
06:21:54FromDiscord<Prestige> sweet
06:27:26FromDiscord<Elegantbeef> Nope order of operations issue as always
06:27:49FromDiscord<Prestige> well damn
06:28:16FromDiscord<Elegantbeef> https://play.nim-lang.org/#ix=3ZTJ
06:28:24FromDiscord<Elegantbeef> We could do it unsafely with just idents
06:28:49FromDiscord<Elegantbeef> So you'd do `mock(doThing, proc() = echo "no")` and it'd replace all `doThing` with the name of that proc
06:29:42FromDiscord<Elegantbeef> i mean we could make it a tinge safer with checking the type and if the module is the same
06:29:56FromDiscord<Elegantbeef> so you could do like `mock("mymodule.myProc", ...)`
06:30:41FromDiscord<Prestige> that playground didnt work out
06:30:50FromDiscord<Prestige> it's not code
06:30:55FromDiscord<Elegantbeef> Eh doesnt matter i have a proper implementation incomming

06:53:35FromDiscord<Prestige> maybe use wormhole.app
06:54:00FromDiscord<Elegantbeef> What matrix files are too spooky for you?
06:54:21FromDiscord<Prestige> matrix files?
06:54:34FromDiscord<Prestige> if you mean that wandbox.org thing, that didn't work
06:54:34FromDiscord<Elegantbeef> Matrix supports file uploads
06:54:41FromDiscord<Elegantbeef> It's a multi media protocol

06:56:47FromDiscord<Prestige> ty
06:59:04FromDiscord<Elegantbeef> Would be nice if `noRewrite` was respected
07:04:10FromDiscord<Elegantbeef> If unclear you need to pass `-d:test`
07:06:46FromDiscord<Elegantbeef> and you probably want to do `--hint[Pattern]:off` if you dont like the noise, this way of mocking will cause the compiler to be slower since norewrite isnt respected for whatever reason
07:10:33FromDiscord<Prestige> i'll try to break it

07:39:14FromDiscord<Elegantbeef> Dont export mocker anyway
07:39:36FromDiscord<Elegantbeef> It needs to me imported in all files to work as it's supposed to
07:41:32FromDiscord<Prestige> hmm
07:42:55FromDiscord<Elegantbeef> Dont know if you noticed the config.nims but that's how we're injecting it
08:09:36FromDiscord<Prestige> So it's always implicitly imported, hmm

08:59:55*kayabaNerve joined #nim
09:02:10FromDiscord<Elegantbeef> No you testing framework doesnt need to export any file
09:02:45FromDiscord<Elegantbeef> You have to import that module in all modules to have `mock` work properly
09:03:03FromDiscord<Elegantbeef> So you need to bring that around and use `--import:mocker`

09:37:29FromDiscord<d4rckh> i have to go manually and click detect indentation from file every time i open vs code
09:37:34FromDiscord<d4rckh> (edit) "i have to go manually ... and" added "to each file"
09:37:44FromDiscord<d4rckh> why doesnt it detect the indentation automatically?
09:37:53FromDiscord<j-james> oh that's unexpected
09:38:05FromDiscord<j-james> there should be a "detect indentation" setting
09:38:43FromDiscord<d4rckh> wait i found it
09:38:48FromDiscord<d4rckh> but i swear i enabled it before and it didnt work
09:39:00FromDiscord<d4rckh> now it works 🤦‍♂️
09:39:31FromDiscord<j-james> i've had annoyances with it not indenting with two spaces when creating new files, but existing always works fine
09:39:49FromDiscord<d4rckh> it should do something like
09:40:18FromDiscord<d4rckh> if it detects im indenting manually using 2 spaces, like pressing space 2 times to indent, it should automatically change the behavior of the tab key to insert 2 spaces

15:55:48FromDiscord<Yardanico> oh, if you want to do the same with jester, it doesn't have that functionality
15:55:51FromDiscord<Yardanico> you'll have to do it manually

17:24:00FromDiscord<Phil> It's fine, I semi regularly ask waaaaay dumber questions here
17:24:25Amun-RaI'd use haproxy for reverse proxying
17:24:56FromDiscord<Rika> i'd say haproxy is better for load balancing ironically
17:24:58FromDiscord<Phil> Why not just industry standards like Apache and nginx ?
17:25:10FromDiscord<Rika> haproxy is also industry standard..........
17:25:10Amun-Rait is industry standard
17:25:13FromDiscord<Phil> Oh wait, I'm dumb
17:25:22FromDiscord<Phil> Ah, too slow
17:25:28Amun-Raand it's way better status page than (free) nginx does ;>
17:25:34Amun-Rait's → it has
17:25:37FromDiscord<Rika> yes that is true
17:25:38FromDiscord<Phil> Memory kicked in way to late
17:25:46FromDiscord<Rika> metrics are better on haproxy
17:26:05FromDiscord<Rika> i should prolly migrate my nginx config then
17:26:19FromDiscord<Phil> Hmm, my old workplace used haproxy
17:26:31FromDiscord<Phil> Current one swears on nginx
17:26:36Amun-RaI use nginx as httpd and haproxy for ssl offload/revproxy/lb
17:27:06FromDiscord<Phil> And I'm too unknowing to know if one has cases where they are better than the other
17:29:35*haskellandchill joined #nim
17:31:43FromDiscord<Rika> haproxy is equal with nginx with reverse proxy stuff, but ofc it isnt an httpd
17:32:33Amun-Ramhm
17:33:33FromDiscord<Phil> So basically given I just want it to serve my front-end and forward requests to my backend and serve image /audio files I could just as easily use haproxy ?
17:36:07Amun-Rayes
17:36:37FromDiscord<Phil> Hmmmm
17:36:56FromDiscord<Phil> I might make a second docker image of by project eventually then
17:41:10haskellandchillhi is this the most active chat for nim discussion? I wanted to evaluate Nim's feature claims like https://mawfig.github.io/2022/06/18/v-lang-in-2022.html did for V lang. I expect Nim to do much better than V did.
17:42:17FromDiscord<huantian> Yeah this is probably the most active chat
17:42:35haskellandchillok and if I access it from discord it's the same basically?
17:42:49FromDiscord<Phil> Pretty much
17:42:57FromDiscord<huantian> Mhm the chat is bridged between discord, irc, and matrix
17:44:13FromDiscord<huantian> Depending on your topic it might be better to make a forum post tho
17:45:25*haskellandchill quit (Quit: Client closed)
17:45:33FromDiscord<Phil> Aye. Form post is more likely to get attention if you want some more elaborate answers
17:45:50FromDiscord<haskellandchill> interesting
17:46:07FromDiscord<dom96> Matrix<->Discord<->IRC. It's all linked together here
17:46:29FromDiscord<Elegantbeef> Even had telegram at one point but "They're too noisey" 😄
17:46:30FromDiscord<haskellandchill> I just want to be fair to the community and also yeah not be missing anything basic with my approach

17:49:31FromDiscord<haskellandchill> one thing I can't figure out is how to refer to `$` as a function

17:50:28FromDiscord<haskellandchill> Makes sense
17:51:58FromDiscord<haskellandchill> It seems contradictory to the goal in the faq
17:52:07FromDiscord<dom96> The segfault in that case can be thought of as a NilPointerException and indeed there is a Nim module which makes it so: https://nim-lang.org/docs/segfaults.html
17:52:22FromDiscord<haskellandchill> I understand why it's happening and that it's intended behavior
17:52:26FromDiscord<dom96> (edit) "NilPointerException" => "NilAccessException"
17:52:30FromDiscord<Elegantbeef> Nim does have mechanisms for no nil in `experimenta:strictNotNil`
17:52:51FromDiscord<haskellandchill> ooo
17:53:11FromDiscord<Elegantbeef> Though as the name implies it's not complete
17:53:15FromDiscord<Phil> In reply to @Elegantbeef "Nim does have mechanisms": Aaaaand bookmarked
17:53:25FromDiscord<Elegantbeef> https://nim-lang.org/docs/manual_experimental.html#strict-not-nil-checking
17:53:37FromDiscord<Yardanico> In reply to @haskellandchill "ooo": also just to be clear - nim and rust are different in quite a lot of things
17:53:43FromDiscord<Yardanico> even the basic approach to safety/etc is very different
17:53:46FromDiscord<haskellandchill> oh for sure
17:53:49FromDiscord<Yardanico> and memory management
17:53:51FromDiscord<haskellandchill> I'm just using it as an example
17:54:07FromDiscord<haskellandchill> oh how it could be handled to be more in line with the faq statement: "How about security and memory safety?↵Nim provides memory safety by not performing pointer arithmetic, with optional checks, traced and untraced references and optional non-nullable types."
17:54:20FromDiscord<haskellandchill> specifically a "traced reference"
17:54:24FromDiscord<Yardanico> a lot of the manual is quite old, yes
17:54:47FromDiscord<Elegantbeef> Memory safety also isnt a overwhelmingly concise term
17:55:02FromDiscord<Elegantbeef> Depending on what you consider it means changes what that means 😄
17:55:17FromDiscord<haskellandchill> the goal of the project is to be more precise and have verified support for language claims
17:55:35FromDiscord<haskellandchill> (edit) "the goal of the project is to be more precise ... and" added "with"
17:56:05FromDiscord<haskellandchill> but I believe that experimental feature is in line with it
17:56:49FromDiscord<haskellandchill> `nim c --experimental:strictNotNil file.nim`?
17:57:10FromDiscord<Elegantbeef> Yep or you can just include `{.experimental: "strictNotNil".}` in the fiile before your nilable code
17:57:43FromDiscord<haskellandchill> hm it doesn't seem to do anything for this case
17:57:53FromDiscord<haskellandchill> are there any examples for it?
17:58:00FromDiscord<Elegantbeef> You need to annotate the type is nilable
17:58:07FromDiscord<Elegantbeef> Scroll down on that link
17:58:08FromDiscord<Rika> you mean not nilable
17:58:41FromDiscord<haskellandchill> oh cool thanks
17:59:02FromDiscord<Elegantbeef> It doesnt turn all `ref T` into `not nil` only the ones you annotate
17:59:38FromDiscord<Elegantbeef> It also isnt complete so there are probably bugs and the like, but it's there so thought i'd mention it
17:59:59FromDiscord<haskellandchill> this syntax confuses me
17:59:59FromDiscord<haskellandchill> sent a code paste, see https://play.nim-lang.org/#ix=40tW
18:00:07FromDiscord<Rika> ? in what whay
18:00:08FromDiscord<Rika> (edit) "whay" => "way"
18:00:15FromDiscord<Elegantbeef> Object is a type alias to `NilableObject not nil`
18:00:17FromDiscord<haskellandchill> hm so I need two types to do it?
18:00:21FromDiscord<Rika> not necessarily
18:00:22FromDiscord<Elegantbeef> Yes
18:00:26FromDiscord<Rika> wait really?
18:00:34FromDiscord<Rika> you cant directly `ref object not nil`?
18:00:39FromDiscord<haskellandchill> I tried that
18:00:41FromDiscord<haskellandchill> it didn't work
18:00:46FromDiscord<Elegantbeef> You cannot directly do that rika
18:00:47FromDiscord<Rika> when did it change
18:00:53FromDiscord<Rika> prolly read the rfc and forgot
18:01:00FromDiscord<Elegantbeef> `notNil` vs `strictNotNil`
18:01:29FromDiscord<haskellandchill> oh there's another?
18:01:41FromDiscord<Elegantbeef> Actually no nevermind neither support it
18:01:54FromDiscord<Elegantbeef> Eh `notNil` was a different implementation that is really deprecated by the latter
18:02:08FromDiscord<huantian> There are some alternative ways to make ref objects nil safe like Option and byref ig↵↵Or just don’t use ref objects
18:02:53FromDiscord<huantian> Oh is notNil just an older version? I was always confused why there’s two
18:02:58FromDiscord<Elegantbeef> I think the definition Nim uses of memory safe is more along the lines of "Memory is never lost and is always freed"
18:03:03FromDiscord<haskellandchill> byref ig?
18:03:21FromDiscord<Elegantbeef> Yea i think `notNil` was an old implementation that's only kept around due to possible old code that relies on it
18:06:35FromDiscord<Elegantbeef> I don't think the current implementation of `strictNotNil` actually catches a field access oddly
18:06:49FromDiscord<dom96> sent a code paste, see https://play.nim-lang.org/#ix=40tZ
18:07:19FromDiscord<Elegantbeef> It's probably just easier on the parser this way
18:08:27FromDiscord<haskellandchill> hm it doesn't seem to catch field access
18:08:40FromDiscord<haskellandchill> but I can change the example
18:09:06FromDiscord<Elegantbeef> I dont think it presently ever assumes the `not nil` object can be nil
18:09:19FromDiscord<Elegantbeef> So yea that's one of those bugs i mentioned 😄
18:10:32FromDiscord<haskellandchill> > We show an error for each dereference ([], .field, [index] () etc) which is of a tracked expression which is in MaybeNil or Nil state.
18:10:39FromDiscord<huantian> Pragma you can use on non-ref value types to make them pass by reference iirc↵(@haskellandchill)
18:10:45FromDiscord<haskellandchill> what does it mean by "We show an error"
18:10:54FromDiscord<haskellandchill> compile error? doesn't seem to
18:11:02FromDiscord<Elegantbeef> Eh huan most types are passed by ref as they're larger than 3 floats
18:11:14FromDiscord<Yardanico> both of these not nil things are unfinished, I don't think they ever worked as advertised :)
18:11:36FromDiscord<Elegantbeef> Eh yard it works just on `Nilable -> not nil` it doesnt work on the `not nil` part presently
18:11:40FromDiscord<dom96> it's also unclear what their future looks like, there were questions posed in https://github.com/nim-lang/RFCs/issues/437 but not answered
18:11:59FromDiscord<Elegantbeef> It's intended to be kept
18:12:08FromDiscord<Elegantbeef> > "Not nil annotation" -- Should be planned for Nim 2.x but removed from the "experimental" manual.
18:12:10FromDiscord<Yardanico> ? https://media.discordapp.net/attachments/371759389889003532/988144172835930272/unknown.png
18:12:18FromDiscord<Yardanico> although it's a stretch goal
18:12:45FromDiscord<Elegantbeef> yardanico that's for `out` parameters
18:14:16FromDiscord<huantian> We have our parameters??
18:14:23FromDiscord<Elegantbeef> No we do not
18:14:38FromDiscord<Elegantbeef> It's reserved in the language and araq wants them for definite assignment
18:17:50FromDiscord<huantian> Interesting
18:18:03FromDiscord<huantian> I can’t tell if this convo was helpful or confusing lmao
18:18:13FromDiscord<haskellandchill> woa strictNotNil worked without the `not nil` annotation
18:19:17FromDiscord<Elegantbeef> Uhh?

18:21:16FromDiscord<Yardanico> sent a code paste, see https://play.nim-lang.org/#ix=40u2
18:21:21FromDiscord<Yardanico> but of course you can always turn warnings into errors
18:21:26FromDiscord<dom96> cool
18:22:01FromDiscord<ElegantBeef> odd it doesnt work for field access right now 😄
18:22:31FromDiscord<haskellandchill> how do I turn warnings into errors?
18:23:10FromDiscord<Elegantbeef> `--warningAsError[StrictNotNil]` i think
18:23:20FromDiscord<haskellandchill> oh I can't do it for all warnings?

18:28:34FromDiscord<Elegantbeef> You call `echo t.x`
18:28:39FromDiscord<haskellandchill> ah
18:29:23FromDiscord<Phil> In reply to @reversem3 "What am I doing": I'll take a look in an hour or so, currently only on phone and on phone it looks too garbled to properly see anything
18:29:41FromDiscord<Elegantbeef> Even at a desktop it's too garbled
18:29:59FromDiscord<Phil> Ah so that wasn't my phone
18:30:48reversem3[m]Its showing the errors from vim
18:30:59FromDiscord<Phil> In that case could you also add a clean copy paste of a minimal example reversem3?
18:31:05reversem3[m]do you want me to post without the errors
18:31:15reversem3[m]ok
18:32:28reversem3[m]https://play.nim-lang.org/#ix=40u4
18:32:34reversem3[m]no errors , sorry about that
18:32:51reversem3[m] * no error in the paste now , sorry about that
18:33:05FromDiscord<Phil> That's f fine
18:33:39FromDiscord<Phil> You can't access the dB like that. First things first, you using sqlite or postgres?
18:34:15reversem3[m]db_postgres
18:34:38FromDiscord<Phil> Because your key problem is you're trying to use a dB connection (dB) without creating it first
18:35:57FromDiscord<Phil> Norm has a template for that, let me see
18:36:31reversem3[m]So this doesn't work ? `import std/db_postgres
18:36:31reversem3[m]let db = open("localhost", "user", "password", "dbname")
18:36:31reversem3[m]db.close()`
18:37:55FromDiscord<Phil> It does but the line running create tables is line 21
18:38:06FromDiscord<Phil> You create the connection way later
18:40:12NimEventerNew thread by Bulat_Ziganshin: Lifetime of pointer returned by str.cstring, see https://forum.nim-lang.org/t/9247
18:40:16reversem3[m]Ok, so I shouldn't have a separate file for opening the connection then?
18:40:24FromDiscord<Phil> Although even then you might get ringtone errors because those login credentials do not look like valid postgres login credentials. However, I have not used postgres before so no idea if those are some sort of valid default
18:42:07FromDiscord<Phil> Ohhh wait .. Oh fuck it, this is too painful on phone, I'll look at it when I'm in front of a computer.
18:44:05FromDiscord<haskellandchill> ringtone errors?
18:44:57FromDiscord<huantian> Probably autocorrect from runtime
18:46:35FromDiscord<haskellandchill> ah I was picturing somehow opening a connection to postgres like a dial up modem
18:47:40FromDiscord<Phil> Runtime
18:47:49FromDiscord<Phil> Not ringtone. Gna

19:51:19FromDiscord<exelotl> In reply to @Elegantbeef "I havent used it": I mean, the OOP aspect is exactly what I want, the thing is before doing a query you're expected to have a fully instantiated object which will be populated with the results of the query, but if that object (or any of its fields which are also model objects) happen to be `nil` then it just segfaults :x
19:51:30*kayabaNerve_ quit (Ping timeout: 240 seconds)
19:51:35FromDiscord<Elegantbeef> What?
19:52:06FromDiscord<Elegantbeef> I dont know Norm related APIs but given phil's code i didnt see any benefit in the OOP method of code, i could be wrong
19:53:21*Jjp137 joined #nim
19:54:08FromDiscord<Elegantbeef> Like does it actually benefit from being able to dynamically point at any model, or is it all mostly static?

19:55:04FromDiscord<exelotl> oh, you mean like that

19:57:44*PMunch quit (Quit: leaving)
19:58:05FromDiscord<exelotl> seems mostly just useful as a way to ensure every model has the necessary internal fields (e.g. `id`)
19:58:27FromDiscord<Elegantbeef> Yea that's my point concepts + value type inheritance works
19:58:34FromDiscord<Elegantbeef> For instance
19:58:37FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=40ui
19:59:49FromDiscord<Elegantbeef> But i really should make it clear i've never used Norm or anything like it so i dont even know what it does

20:43:47*noeontheend joined #nim
20:55:21FromDiscord<Phil> In reply to @reversem3 "https://play.nim-lang.org/#ix=40u4": Alright, finally can look at it on a proper screen
20:56:08FromDiscord<Phil> Issue 1) You don't import the postgres module in norm. the norm/model module is for defining models. The methods for doing things on a given database are in the sqlite/postgres modules
20:57:05FromDiscord<Phil> Issue 2) db is a DbConn object from std/db_sqlite (which norm has its own version of but they are literally the same type
20:57:24FromDiscord<Phil> (edit) "type" => "thing and can be used interchangeably)"
20:57:32FromDiscord<Phil> (edit) "interchangeably)" => "interchangeably). It does not have a "userFoo" attribute"
20:57:57FromDiscord<Phil> (edit) "Issue 2) db is a DbConn object from std/db_sqlite (which norm has its own version of but they are literally the same thing and can be used interchangeably). It does not have a "userFoo" attribute ... " added "(The echo `db.userFoo` will get you there)"
20:59:40FromDiscord<Phil> (Minor) Issue 3) Which won't be a runtime error but is in general advisable: database connection pooling is neat and saves you the runtime-effort of creating and destroying database connections all the time.
21:00:56FromDiscord<Phil> Issue 4) You might want to double check if you can access your postgres database with neither a username nor a password (since you pass those as empty strings).
21:01:06FromDiscord<Phil> (edit) "strings)." => "strings when creating a connection)."
21:01:10FromDiscord<Elegantbeef> I see phil has replaced me 😄
