2021-03-24 08:36:55 × dbmikus quits (~dbmikus@cpe-76-167-86-219.natsow.res.rr.com) (Ping timeout: 256 seconds)
2021-03-24 08:37:16 <bahamas> the library you're talking about sounds familiar (although I don't remember the name). however, I fear it uses too many abstractions, which might not be necessary for what I'm trying to do
2021-03-24 08:38:19 → Foritus joins (~buggery@cpc91316-watf11-2-0-cust68.15-2.cable.virginm.net)

2021-03-24 08:38:28 <bahamas> I have another question. I see some warnings regarding automatic deriving "No deriving strategy specified. Did you want stock, newtype, or anyclass?
2021-03-24 08:38:59 → hiroaki joins (~hiroaki@2a02:8108:8c40:2bb8:a7dd:a3bb:c8b0:2d88)
2021-03-24 08:39:01 <bahamas> do I have to specify the strategy on each deriving declaration, or is there a different approach?
2021-03-24 08:39:07 × Foritus quits (~buggery@cpc91316-watf11-2-0-cust68.15-2.cable.virginm.net) (Remote host closed the connection)

2021-03-24 08:43:39 → kuribas joins (~user@ptr-25vy0i8r3m7ulrlbw64.18120a2.ip6.access.telenet.be)
2021-03-24 08:44:02 <ski> i guess the laste paragraph on that page applies in your case, and you then have to explicitly specify the strategies in which there's an ambiguity reported
2021-03-24 08:45:38 → xourt joins (d4c620ea@212-198-32-234.rev.numericable.fr)

2021-03-24 08:47:25 → Foritus joins (~buggery@cpc91316-watf11-2-0-cust68.15-2.cable.virginm.net)
2021-03-24 08:48:30 <bahamas> ski: I'm deriving Show and Generic for a record and a sum type
2021-03-24 08:48:42 → maroloccio_ joins (~marolocci@pousada3ja.mma.com.br)
2021-03-24 08:49:01 <bahamas> so none of them are a newtype. I'm assuming the warning shows up, because I have GeneralizedNewtypeDeriving enabled
2021-03-24 08:50:09 <bahamas> ok, this is just a warning, so I'll ignore it for now
2021-03-24 08:51:07 <ski> so the ambiguity is between `stock' and `anyclass', for `Show', i think

2021-03-24 08:52:34 <ski> hm
2021-03-24 08:54:39 <bahamas> I have a question regarding records and json. I know that one pattern is to prefix each record field to prevent clashes. for example data User = { uName :: Text, uAge :: Int }. but the incoming json is usually { name: "foo", age: 26 }. is there a way to handle this automatically?
2021-03-24 08:55:50 × heatsink quits (~heatsink@2600:1700:bef1:5e10:b09b:3609:dd4b:42c9) (Ping timeout: 264 seconds)
2021-03-24 08:55:55 → kritzefitz joins (~kritzefit@p548c9398.dip0.t-ipconnect.de)
2021-03-24 08:56:01 <kuribas> bahamas: the duplicaterecordfields extension
2021-03-24 08:56:38 <kuribas> bahamas: And if you use that, the namedFieldPuns and recordWildCards extensions are very handy.
2021-03-24 08:56:48 <kuribas> Because it makes manipulating records much easier.

2021-03-24 08:58:12 <xsperry> IIRC json will handle it automatically if your field names start with data name. so data User = { userName :: Text, userAge :: Int }
2021-03-24 08:58:25 × Foritus quits (~buggery@cpc91316-watf11-2-0-cust68.15-2.cable.virginm.net) (Quit: ლ(ಠ益ಠლ) .:. <Ashley> my porn is hidden in a folder called "BBC Micro Emulator")
2021-03-24 08:58:40 <kuribas> bahamas: or alternatively you can also use a conversion function in the genericToJSON
2021-03-24 08:58:53 <kuribas> xsperry: that's not automatic, you need to write it yourself.

2021-03-24 09:00:07 × MichaelHoffmannb quits (brisadmozi@gateway/shell/matrix.org/x-cvnnmjtfpdwpnugh) (Quit: Idle for 30+ days)
2021-03-24 09:00:28 <kuribas> bahamas: https://hackage.haskell.org/package/aeson-1.5.6.0/docs/Data-Aeson.html#v:fieldLabelModifier
2021-03-24 09:00:43 <bahamas> kuribas: yeah. that's my current solution
2021-03-24 09:01:02 <kuribas> bahamas: then what is the question?
2021-03-24 09:01:07 <bahamas> kuribas: that involves copying a JsonUtils file in all projects. I was wondering if someone abstracted this
2021-03-24 09:01:11 × Foritus quits (~buggery@cpc91316-watf11-2-0-cust68.15-2.cable.virginm.net) (Client Quit)
2021-03-24 09:01:20 <kuribas> JsonUtils?
2021-03-24 09:01:24 <kuribas> it's part of Aeson
2021-03-24 09:01:33 <bahamas> kuribas: that's just how I named the file
2021-03-24 09:01:40 <kuribas> And how much more abstraction do you want then genericToJSON?
2021-03-24 09:02:06 <kuribas> you can always write, myCustomToJSON = genericToJSON optionOverrides
2021-03-24 09:02:09 <bahamas> kuribas: https://bpa.st/DLGA
2021-03-24 09:02:23 <bahamas> this is my current implementation
2021-03-24 09:03:00 <kuribas> bahamas: and?
2021-03-24 09:03:05 <kuribas> I don't see the problem
2021-03-24 09:03:11 <bahamas> hey, I was just wondering if anybody did this. maybe it's not general enough or maybe it's not worth making a library out of it
2021-03-24 09:03:21 <bahamas> it's ok if that's the case. I just thought I'd ask
2021-03-24 09:03:48 → Franciman joins (~francesco@host-79-53-62-46.retail.telecomitalia.it)
2021-03-24 09:05:01 <kuribas> that would be very useful IMO...
2021-03-24 09:05:06 <kuribas> wouldn't
2021-03-24 09:05:15 <kuribas> it's fairly easy to implement
2021-03-24 09:06:00 → wonko7 joins (~wonko7@45.15.17.60)
2021-03-24 09:06:03 <bahamas> sure. at the same time, I think the pattern of prefixing labels with lowercase letters is widespread. so it could be an alternative option provided by aeson
2021-03-24 09:06:16 <bahamas> but I don't have strong feelings for this. it's just a thought
