2020-10-13 10:42:41 <Uniaika> god damnit
2020-10-13 10:43:34 <Uniaika> I'm having this JSON format to parse and I can't seem to make sense of what to do
2020-10-13 10:43:49 <Uniaika> I have *two* top-level field, that are to be unified in a sum type in Haskell-land
2020-10-13 10:45:44 <Uniaika> so naturally I'm writing such an instance https://ghostbin.co/paste/r64hne2
2020-10-13 10:46:30 <Uniaika> (surprise, doesn't compile)
2020-10-13 10:47:00 × bliminse quits (~bliminse@host217-42-95-37.range217-42.btcentralplus.com) (Ping timeout: 256 seconds)
2020-10-13 10:47:30 × L29Ah quits (~L29Ah@unaffiliated/l29ah) (Ping timeout: 272 seconds)
2020-10-13 10:47:44 → bliminse joins (~bliminse@host217-42-95-37.range217-42.btcentralplus.com)
2020-10-13 10:49:13 → p8m joins (p8m@gateway/vpn/protonvpn/p8m)
2020-10-13 10:49:25 × Stanley00 quits (~stanley00@unaffiliated/stanley00) ()
2020-10-13 10:49:58 × p8m_ quits (p8m@gateway/vpn/protonvpn/p8m) (Ping timeout: 260 seconds)
2020-10-13 10:50:25 → thir joins (~thir@p200300f27f02580060eb7dde324e54c8.dip0.t-ipconnect.de)
2020-10-13 10:52:43 <fendor> Uniaika, in the example, aren't you missing the unifying sum type?
2020-10-13 10:55:05 <Uniaika> >_> sorry, I'll edit the snippet
2020-10-13 10:55:12 × thir quits (~thir@p200300f27f02580060eb7dde324e54c8.dip0.t-ipconnect.de) (Ping timeout: 260 seconds)
2020-10-13 10:55:40 <Uniaika> fendor: reload, it's been added
2020-10-13 10:55:54 × rprije quits (~rprije@203.214.95.251) (Ping timeout: 265 seconds)
2020-10-13 10:56:48 <fendor> Uniaika, and why doesn't it compile? Code-snippet looks roughly good to me
2020-10-13 10:58:38 × John20 quits (~John@82.46.59.122) (Ping timeout: 258 seconds)
2020-10-13 11:01:08 <merijn> heh
2020-10-13 11:01:21 <Uniaika> fendor: https://ghostbin.co/paste/r64hne2
2020-10-13 11:01:24 <Uniaika> here is the error
2020-10-13 11:01:25 <merijn> "maybe" is exported from Prelude?
2020-10-13 11:01:31 → bahamas joins (~lucian@unaffiliated/bahamas)
2020-10-13 11:01:38 <Uniaika> merijn: yes, I think so
2020-10-13 11:01:56 <Uniaika> fendor: also, I think I have a hard time expressing the fact that they may be null, but not at the same time?
2020-10-13 11:02:17 × xelxebar quits (~xelxebar@gateway/tor-sasl/xelxebar) (Remote host closed the connection)
2020-10-13 11:02:24 <Uniaika> I mean, if it were an object, I'd use (.:?)
2020-10-13 11:02:31 <nshepperd> this looks like a job for Alternative
2020-10-13 11:02:50 → xelxebar joins (~xelxebar@gateway/tor-sasl/xelxebar)
2020-10-13 11:03:00 <Uniaika> hmm
2020-10-13 11:03:04 <Uniaika> sounds like it yeah
2020-10-13 11:03:30 <Uniaika> but every tutorial under the sun seems to be operating on an object, and not with top-level values, so I don't know how much they apply?
2020-10-13 11:03:33 → lemmih__ joins (~lemmih@218.186.157.57)
2020-10-13 11:03:34 <Uniaika> hmm.
2020-10-13 11:03:41 <Uniaika> I'll try something
2020-10-13 11:03:58 <Uniaika> (thanks for being rubber ducks, it's incredibly helpful to be able to lay down my thoughts)
2020-10-13 11:04:28 <fendor> Uniaika, I think the type for field2 is wrong, too. Don't you need Data.UUID.fromText ?
2020-10-13 11:04:57 <Uniaika> fendor: well, since there is already a FromJSON instance for UUID, I thought it would work out-of-the-box?
2020-10-13 11:05:07 × chaosmasttter quits (~chaosmast@p200300c4a711b00135524723c22b3f52.dip0.t-ipconnect.de) (Ping timeout: 260 seconds)
2020-10-13 11:05:13 <nshepperd> what exactly do you mean by a top level field
2020-10-13 11:05:37 <nshepperd> value, whatever
2020-10-13 11:05:41 <Uniaika> I'll add the desired JSON representation to the snippet
2020-10-13 11:05:55 × lemmih_ quits (~lemmih@2406:3003:2072:44:9dc:f2e9:a002:8d1a) (Ping timeout: 240 seconds)

2020-10-13 11:06:32 × bahamas quits (~lucian@unaffiliated/bahamas) (Ping timeout: 265 seconds)
2020-10-13 11:06:34 <fendor> Uniaika, I don't think `withText` gives you a text and then you have to specify a value parser for that text. Doesnt use the instance automatically
2020-10-13 11:07:04 <nshepperd> that usage of withText doesn't look right anyhow
2020-10-13 11:07:12 <fendor> indeed
2020-10-13 11:07:27 <nshepperd> The first argument is only used for the error message
2020-10-13 11:08:50 <Uniaika> fendor, nshepperd : https://ghostbin.co/paste/r64hne2
2020-10-13 11:09:04 <merijn> Uniaika: I recommend using a different pastebin, that one is terrible
2020-10-13 11:09:09 <Uniaika> ah shit
2020-10-13 11:09:10 <Uniaika> sorry
2020-10-13 11:09:15 <Uniaika> dpaste?
2020-10-13 11:09:19 <merijn> It apparently requires me enabling cookies AND solving a captcha to read things
2020-10-13 11:09:21 <merijn> screw that
2020-10-13 11:09:23 <Uniaika> I think hpaste is dead now, right?
2020-10-13 11:09:25 <dminuoso> https://paste.tomsmeding.com/
2020-10-13 11:09:32 <dminuoso> Is the spiritual hpaste successor
2020-10-13 11:09:41 <Uniaika> https://paste.tomsmeding.com/QMFidUu1
2020-10-13 11:09:45 <Uniaika> dminuoso: thx
2020-10-13 11:09:49 <fendor> well, for Foo, it could be something like: `parseJSON v = Field1 <$> v .: "field1" <|> Field2 <$> v .: "field2"`
2020-10-13 11:09:52 <merijn> tomsmeding is the hero #haskell needed ;)
2020-10-13 11:10:04 → John20 joins (~John@82.46.59.122)
2020-10-13 11:10:10 <merijn> He resurrected ircbrowse too, so now I can be self-concious about how much time I spend here :p
2020-10-13 11:10:18 <Uniaika> fendor: ooooh
2020-10-13 11:10:30 <merijn> tomsmeding: oh, maybe you should send a mail to Haskell Weekly to publicize those two?
2020-10-13 11:10:36 × snakemas1 quits (~snakemast@213.100.206.23) (Ping timeout: 260 seconds)

2020-10-13 11:11:49 → mmohammadi981266 joins (~mmohammad@188.210.103.147)
2020-10-13 11:12:04 × mmohammadi981266 quits (~mmohammad@188.210.103.147) (Client Quit)
2020-10-13 11:12:14 <Uniaika> fendor: but (.:) is expecting a HashMap right?
2020-10-13 11:12:25 <tomsmeding> merijn: I'm not sure it would be a good idea to publicise ircbrowse that way, given that it's not my project... :p
2020-10-13 11:12:53 <dminuoso> Uniaika: No.
2020-10-13 11:12:56 <merijn> tomsmeding: It's open source, you just forked/maintained it
2020-10-13 11:13:05 <dminuoso> (.:) :: FromJSON a => Object -> Text -> Parser a
