| 2025-12-19 18:01:14 +0100 | <yin> | prelude doesn't even help |

| 2025-12-19 18:00:25 +0100 | <yin> | i mean the potential is there |
| 2025-12-19 18:00:14 +0100 | <yin> | mari-estel: my idealized version of Haskell :) |
| 2025-12-19 17:59:48 +0100 | <mari-estel> | yin: in comparison with? |
| 2025-12-19 17:59:28 +0100 | <yin> | merijn: i'm always sad that Haskell requires so much verbosity in order to guarantee correctness |
| 2025-12-19 17:57:15 +0100 | <sprout> | I would assume it works in haskell too. and even be faster due to laziness |
| 2025-12-19 17:56:46 +0100 | <sprout> | milan2: it works for me, but that's egel code |
| 2025-12-19 17:56:01 +0100 | <milan2> | Anyway sprout so scanl should work for 2015 d1 p2? |
| 2025-12-19 17:55:45 +0100 | <yin> | hey, i did sign main |
| 2025-12-19 17:54:43 +0100 | <milan2> | yin: Look yin even with type signatures! Not like yours ;) |
| 2025-12-19 17:54:33 +0100 | <yin> | yes i was happy for having only 12 days to worry about this week but i got to day 8 until work swallowed my free time |
| 2025-12-19 17:53:12 +0100 | <milan2> | :D |
| 2025-12-19 17:52:51 +0100 | <yin> | :D |
| 2025-12-19 17:52:46 +0100 | <yin> | merijn: tl;dr |
| 2025-12-19 17:52:37 +0100 | <merijn> | I immediately got sidetracked by work after doing the first day this year >.> |
| 2025-12-19 17:52:20 +0100 | <merijn> | yin: I always go for most readable and most correct: https://github.com/merijn/AdventOfCode/blob/master/Day1.hs |
| 2025-12-19 17:51:14 +0100 | <yin> | not the most readable, one can argue |
| 2025-12-19 17:50:19 +0100 | <milan2> | Lovely really few lines of code even with IO and both parts. |

| 2025-12-19 17:48:15 +0100 | <yin> | my day 1 this year: https://paste.jrvieira.com/1766162825403 |
| 2025-12-19 17:47:30 +0100 | <milan2> | I am glad I started with older ones. |
| 2025-12-19 17:47:25 +0100 | <yin> | milan2: good on you for starting at the beginning |
| 2025-12-19 17:45:54 +0100 | fp | (~Thunderbi@2001-14ba-6e24-3000--198.rev.dnainternet.fi) fp |
| 2025-12-19 17:45:32 +0100 | <probie> | For day 1, this year's was definitely annoying. I messed up day 1 part 2 on the first go, because I hadn't realised the values over 100 were in the data, since part 1 was all modulo 100 |
| 2025-12-19 17:43:46 +0100 | lambda_gibbon | (~lambda_gi@208.83.175.39) |
| 2025-12-19 17:41:30 +0100 | <sprout> | I just throw an exception when I am lazy |
| 2025-12-19 17:40:54 +0100 | <merijn> | milan2: oh, then it's just coicidence your question seems related to this year's day 1 part 2 |
| 2025-12-19 17:40:34 +0100 | <yin> | oh i used scanl |
| 2025-12-19 17:40:21 +0100 | <milan2> | merijn: I started from begining. |
| 2025-12-19 17:40:18 +0100 | <lambdabot> | Traversable t => (s -> a -> (s, b)) -> s -> t a -> (s, t b) |
| 2025-12-19 17:40:17 +0100 | <merijn> | :t mapAccumL |
| 2025-12-19 17:40:14 +0100 | <merijn> | Avoiding spoilers, my implementation relied on mapAccumL |
| 2025-12-19 17:39:48 +0100 | <milan2> | sprout: So scan hmmm... or maybe custom self recursive function. |
| 2025-12-19 17:39:31 +0100 | <yin> | sprout: scanr, which is foldr in disguise |
| 2025-12-19 17:39:20 +0100 | <merijn> | 2025 you mean? :p |
| 2025-12-19 17:38:46 +0100 | <sprout> | scan will give you a list of numbers, and you can terminate when you hit -1 |
| 2025-12-19 17:38:36 +0100 | <yin> | fun to see that i can press ctrl-c to halt `foldl const 0 (repeat ())` in ghci but not foldl' |
| 2025-12-19 17:37:02 +0100 | <sprout> | use scan |
| 2025-12-19 17:36:45 +0100 | <yin> | ironically, because it wouldn't terminate |
| 2025-12-19 17:36:24 +0100 | <lambdabot> | Terminated |
| 2025-12-19 17:36:07 +0100 | <yin> | > foldl' const 0 (repeat ()) |
| 2025-12-19 17:35:57 +0100 | <lambdabot> | 0 |
| 2025-12-19 17:35:55 +0100 | <yin> | > foldl' const 0 [undefined] |
| 2025-12-19 17:35:10 +0100 | <milan2> | Like we need definitelly left fold, and we need to stop counting as soon as we count -1. |
| 2025-12-19 17:34:16 +0100 | <milan2> | Advent of Code 2015 day 1 part 2 broke me :( |
| 2025-12-19 17:33:46 +0100 | <merijn> | What are you actually trying to do? |
| 2025-12-19 17:33:25 +0100 | <milan2> | I probably can't so this will not work on infinite lists. |
| 2025-12-19 17:33:15 +0100 | <merijn> | So you can short-circuit in skipping some evaluation of `f`, but you *have* to walk the list |
