2021-04-27 21:45:08 <cheater> hmm my system's ghc comes with libffi.so.7 so i just symlinked it into path and i guess that works
2021-04-27 21:45:21 <cheater> LD_PATH or whatever
2021-04-27 21:45:31 × danvet quits (~Daniel@2a02:168:57f4:0:efd0:b9e5:5ae6:c2fa) (Ping timeout: 260 seconds)
2021-04-27 21:45:44 <cheater> tomsmeding: could you check gitter when you're around :)

2021-04-27 21:50:58 × pbgc quits (~pbgc@a89-152-234-147.cpe.netcabo.pt) (Quit: Computer has gone to sleep.)
2021-04-27 21:52:43 <lechner> Hi, I am a noobie who bit off too much. I would like to rewrite a Node.js website in Purescript but have some serious type confusion. any hinters would be appreciated. line 78 from the error is line 115 in the paste https://dpaste.org/T9bg
2021-04-27 21:53:32 × zebrag quits (~inkbottle@aaubervilliers-654-1-79-166.w86-212.abo.wanadoo.fr) (Quit: Konversation terminated!)
2021-04-27 21:54:19 <lechner> send returns HandlerM but the database query just before it messes everything up
2021-04-27 21:54:37 × slack1256 quits (~slack1256@200-112-79-247.baf.movistar.cl) (Ping timeout: 252 seconds)
2021-04-27 21:55:10 <monochrom> Is there a purescript channel so you can talk to better matching people?
2021-04-27 21:55:45 <monochrom> Or is my favourite correlation true again?
2021-04-27 21:56:42 × geekosaur quits (930099da@rrcs-147-0-153-218.central.biz.rr.com) (Quit: Connection closed)
2021-04-27 21:57:04 → geekosaur joins (930099da@rrcs-147-0-153-218.central.biz.rr.com)
2021-04-27 21:57:27 <geekosaur> I see 38 people and a logger in #purescript
2021-04-27 21:58:12 <lechner> yes I am over there too, but it's a third-party module they do not know, and I have a Haskell problem. plus, it's for a good purpose :)
2021-04-27 21:58:29 <monochrom> math channel : "I can't find accounting help on IRC" :: haskell channel : "I can't find purescript help on IRC"
2021-04-27 21:59:13 <lechner> that's the first unfriendly response i have seen here, but thanks!
2021-04-27 21:59:48 <monochrom> No, I am talking about a negative correlation between channel membership and job opportunities.
2021-04-27 22:00:41 → Alleria joins (~textual@2603-7000-3040-0000-b547-c3a9-933c-ab1d.res6.spectrum.com)
2021-04-27 22:00:54 <Rembane> lechner: That's not Haskell, that's Purescript. There is an excellent Purescript channel on the functional programming Slack. I recommend asking your question there instead.
2021-04-27 22:01:06 Alleria is now known as Guest25703
2021-04-27 22:01:20 × zardoz2 quits (~bc8134e3@217.29.117.252) (Quit: http://www.okay.uz/ (Session timeout))
2021-04-27 22:02:16 <lechner> unfortunately, my browser does not support Slack but I'll ask on IRC
2021-04-27 22:02:33 <lechner> monochrom: i see, sorry i am a volunteer myself
2021-04-27 22:03:45 <lechner> to be honest, i was a bit embarrassed to ask elementary questions (if there is such a thing in haskell) over there
2021-04-27 22:06:25 <lechner> if i were you folks, though, i would adopt PureScript as the ugly duckling. on a node server, which has been called the next PHP, the type safety it provides is a category killer hands down
2021-04-27 22:07:20 <monochrom> But I don't use a node server.
2021-04-27 22:07:21 × ddellaco_ quits (~ddellacos@ool-44c73afa.dyn.optonline.net) (Remote host closed the connection)
2021-04-27 22:08:17 <lechner> your clients may but they can't refactor safely on any project with more tha 500 lines
2021-04-27 22:09:13 <c_wraith> purescript is a different language with different semantics.
2021-04-27 22:09:17 → kiweun joins (~kiweun@2607:fea8:2a62:9600:c1b6:8c92:c92d:e10a)
2021-04-27 22:09:21 <c_wraith> Using it is more like using javascript than haskell
2021-04-27 22:09:48 <c_wraith> (because you can never forget it is javascript underneath)
2021-04-27 22:09:52 <monochrom> For now, I speak for my clients, too.
2021-04-27 22:10:12 <monochrom> But I am not closed to future possibilities whatsoever.
2021-04-27 22:10:16 × bitmapper quits (uid464869@gateway/web/irccloud.com/x-lwoslwzxzqzjzamu) (Quit: Connection closed for inactivity)
2021-04-27 22:10:28 <yushyin> lechner: https://www.purescript.org/ see 'Community' down below
2021-04-27 22:11:07 × dinciorip quits (~dincio@5.171.80.13) (Quit: WeeChat 3.1)
2021-04-27 22:11:10 → pavonia joins (~user@unaffiliated/siracusa)
2021-04-27 22:11:24 <monochrom> I don't think I can find the line of code that the error message refers to.
2021-04-27 22:12:04 <lechner> monochrom: it's 115 but i got your message https://dpaste.org/T9bg#L115
2021-04-27 22:12:24 × dhil quits (~dhil@80.208.56.181) (Quit: Leaving)
2021-04-27 22:12:50 <monochrom> The error message mentions "discard". I can't find "discard".
2021-04-27 22:13:01 × nut quits (~user@roc37-h01-176-170-197-243.dsl.sta.abo.bbox.fr) (Ping timeout: 268 seconds)
2021-04-27 22:13:44 × kiweun quits (~kiweun@2607:fea8:2a62:9600:c1b6:8c92:c92d:e10a) (Ping timeout: 245 seconds)
2021-04-27 22:14:13 <lechner> i think that's the query result. it probably is too hard with a module you do not know https://pursuit.purescript.org/packages/purescript-postgresql-client/3.0.2 https://github.com/rightfold/purescript-postgresql-client
2021-04-27 22:14:31 <lechner> there are too many types you are not familiar with. i get it
2021-04-27 22:14:38 <monochrom> Well, I don't know how to bridge between HandlerM and ExceptT PGError Aff anyway.
2021-04-27 22:14:45 <lechner> in fact, i have the same problem
2021-04-27 22:15:01 × elfets quits (~elfets@ip-37-201-23-96.hsi13.unitymediagroup.de) (Ping timeout: 260 seconds)
2021-04-27 22:15:09 × __monty__ quits (~toonn@unaffiliated/toonn) (Quit: leaving)
2021-04-27 22:16:51 <lechner> no, the problem is that i added lines 111-114 that brought in the monad from line 64. without them everything works, except there is no SQL query :(
2021-04-27 22:16:52 × stree quits (~stree@68.36.8.116) (Ping timeout: 240 seconds)
2021-04-27 22:18:02 <lechner> i really should talk to the Purescript folks. i did not mean to impose and would rather preserve my goodwill here
2021-04-27 22:18:23 <monochrom> Actually, is this simply a matter of doing your "send" outside "withConnection"?
2021-04-27 22:18:47 <lechner> i think so
2021-04-27 22:19:03 <monochrom> Or outside "withTransaction", I don't know which.
2021-04-27 22:21:02 <lechner> i can scrap the transaction for now. the idea came from here (one page down) https://github.com/rightfold/purescript-postgresql-client#usage
2021-04-27 22:21:10 × malumore_ quits (~malumore@151.62.126.111) (Remote host closed the connection)
2021-04-27 22:21:23 → malumore_ joins (~malumore@151.62.126.111)
2021-04-27 22:21:30 → zebrag joins (~inkbottle@aaubervilliers-654-1-79-166.w86-212.abo.wanadoo.fr)
2021-04-27 22:21:45 <lechner> the other issue with #purescript was that server-side Purescript is officialy not supported, but i think that's the big future for them
2021-04-27 22:23:06 <monochrom> Indeed I would think that updating or outputting a web page shouldn't happen until after a DB transaction finishes (so you know it is a success and you are not in the middle of possible retries, rollbacks, race conditions.
