2020-10-11 01:53:31 <Tario> QQ: if I have a JSON that's has the following body:
2020-10-11 01:53:32 <Tario> {
2020-10-11 01:53:32 <Tario> "a": "blabla",
2020-10-11 01:53:32 <Tario> "b" : 24
2020-10-11 01:53:32 <Tario> }
2020-10-11 01:53:32 <Tario> How can I obtain with aeson the value from the key "a" as a Text, in the simplest way possible?

2020-10-11 02:03:58 <int-e> lemmih: I'm pretty sure that 8 would be too small :P
2020-10-11 02:04:23 <int-e> (I counted 9, maybe 10 with cr/lf newlines)
2020-10-11 02:06:29 <lemmih> Hm, right. The JSON is therefore broken. Gotta delete a space or newline.
2020-10-11 02:07:56 <lemmih> Tario: If you don't want to fix the JSON then you can use 'aeson' instead.
2020-10-11 02:08:34 <Tario> oh

2020-10-11 02:12:21 <c_wraith> This is one of those awkward things, where lens-aeson makes the task look like a super-tiny bit of code... But if you have problems, you suddenly need to understand lens.

2020-10-11 02:15:29 <Tario> yes, I've tried using aeson, but still I'm too novice to comprehend it, but I'm still trying.
2020-10-11 02:15:29 <Tario> Like when presented with a JSON like
2020-10-11 02:15:29 <Tario> { "name": "John", "age" : 54}
2020-10-11 02:15:29 <Tario> I would like to obtain the Text value from the "name" key. I tried to do
2020-10-11 02:15:30 <Tario> let name = myJson .: "name"
2020-10-11 02:15:30 <Tario> Or
2020-10-11 02:15:31 <Tario> HashMap.lookup "name" myJson
2020-10-11 02:15:32 <Tario> but that doesn't work
