2020-09-30 14:05:37 → raehik joins (~raehik@cpc96984-rdng25-2-0-cust109.15-3.cable.virginm.net)
2020-09-30 14:05:48 <kuribas> merijn: I was thinking to make a library to pre (post-) process aeson data before (after) parsing/generating.
2020-09-30 14:05:57 × Amras quits (~Amras@unaffiliated/amras0000) (Ping timeout: 260 seconds)
2020-09-30 14:06:03 <kuribas> merijn: to move around fields.
2020-09-30 14:06:26 <kuribas> merijn: in the best case in a typesafe way (using generics).
2020-09-30 14:06:27 <Uniaika> kuribas: aren't there already hooks to do that?
2020-09-30 14:06:49 <kuribas> Uniaika: you mean a handwritten parser?
2020-09-30 14:07:00 <Uniaika> no, hooks in Aeson
2020-09-30 14:07:02 <Uniaika> wait a sec
2020-09-30 14:08:22 → ystael joins (~ystael@209.6.50.55)
2020-09-30 14:08:26 → heatsink joins (~heatsink@107-136-5-69.lightspeed.sntcca.sbcglobal.net)
2020-09-30 14:09:07 <Uniaika> kuribas: https://hackage.haskell.org/package/aeson-1.4.6.0/docs/Data-Aeson.html#g:16
2020-09-30 14:09:12 <Uniaika> option fields
2020-09-30 14:09:33 <kuribas> Uniaika: they only change the strings
2020-09-30 14:09:41 <kuribas> Uniaika: I want to reorder the JSON
2020-09-30 14:09:51 <Uniaika> wait, re-order it?
2020-09-30 14:10:49 <Uniaika> kuribas: that's tricky because objects are unordered while arrays are
2020-09-30 14:10:59 <kuribas> yeah, like {"subfield": {"x": 1, "y": 2}} => {"subfield_x": 1, "subfield_y": 2}
2020-09-30 14:11:19 <Uniaika> ah that's different
2020-09-30 14:11:26 <Uniaika> p. sure you can operate on the AST
2020-09-30 14:11:39 <Uniaika> although, to be fair, I would just use DTOs for that
2020-09-30 14:11:58 <kuribas> Uniaika: of course I can do Value -> Value, but I want something more principled, composable, and bidirectional.
2020-09-30 14:12:09 <Uniaika> and an explicit translation from the first (direct mapping of the object) to the second (better for my business logic)
2020-09-30 14:12:25 <lortabac> kuribas: lens-aeson ?
2020-09-30 14:12:29 → ericsagnes joins (~ericsagne@2405:6580:0:5100:df5:637e:fad1:ac7)

2020-09-30 14:12:50 <kuribas> lortabac: hmm, maybe an isomorphism?

2020-09-30 14:13:25 <lortabac> oh, if you don't want Value -> Value then lens-aeson is probably not the right tool
2020-09-30 14:16:33 <kuribas> well, maybe just Endo Value
2020-09-30 14:16:45 → cr3 joins (~cr3@192-222-143-195.qc.cable.ebox.net)

2020-09-30 15:04:44 <zincy_> Is there a name for this? You have a N x N matrix and have a set of instructions to update elements in the grid
2020-09-30 15:05:08 <zincy_> startCol, endCol, startRow, endRow
2020-09-30 15:05:47 <zincy_> And a function to update each element

2020-09-30 15:10:08 <zincy_> hehe
2020-09-30 15:10:58 <merijn> zincy_: Kinda serious
2020-09-30 15:11:00 <merijn> zincy_: http://www.sac-home.org/lib/exe/fetch.php?media=docs:tutorial.pdf
2020-09-30 15:11:20 <merijn> See chapter 4 on with loops
2020-09-30 15:12:30 <merijn> "tensor comprehensions" are also somewhat related

2020-09-30 15:13:22 <zincy_> thanks!
