| 2025-01-08 17:51:46 +0100 | <tomsmeding> | much as I am usually condescending about the abilities of LLMs, I'm quite sure it can generate the source for `head`. :) |

| 2025-01-08 17:50:49 +0100 | <jokoon> | no idea if he will solve this with chatpgt without help |
| 2025-01-08 17:50:21 +0100 | <lambdabot> | head [] = error "Prelude.head: empty list" |
| 2025-01-08 17:50:20 +0100 | <lambdabot> | head (x:_) = x |
| 2025-01-08 17:50:20 +0100 | <mauke> | @src head |
| 2025-01-08 17:50:14 +0100 | <jokoon> | although to be fair I just had a student send me his haskell homework |
| 2025-01-08 17:49:51 +0100 | <jokoon> | you can guess that I am doing homework haha |
| 2025-01-08 17:49:26 +0100 | <mauke> | yes, that's pretty much how head is defined |
| 2025-01-08 17:49:09 +0100 | <jokoon> | that works |
| 2025-01-08 17:49:06 +0100 | <jokoon> | like this then https://bpa.st/SDXA |

| 2025-01-08 17:45:42 +0100 | <tomsmeding> | you can give multiple equations to a function |
| 2025-01-08 17:45:34 +0100 | <jokoon> | I will try to put an if |
| 2025-01-08 17:45:26 +0100 | <jokoon> | put some if? |
| 2025-01-08 17:45:25 +0100 | <tomsmeding> | what have you tried? |
| 2025-01-08 17:45:18 +0100 | <jokoon> | and how can I raise an error if the list is empty? |
| 2025-01-08 17:44:55 +0100 | <tomsmeding> | which will still crash if f8 gets an empty list |
| 2025-01-08 17:44:47 +0100 | <tomsmeding> | f8 (a : _) = a |
| 2025-01-08 17:44:28 +0100 | <jokoon> | https://bpa.st/KICQ like this? |
| 2025-01-08 17:43:41 +0100 | <tomsmeding> | pattern-match on it? |
| 2025-01-08 17:42:56 +0100 | <jokoon> | can I access the first element of a list without the head function? |

| 2025-01-08 17:41:04 +0100 | <merijn> | ah, no I'm misremebering it seems, it's from 2018 |
| 2025-01-08 17:40:05 +0100 | <merijn> | sm: So that should be MORE than old enough to require ;) |
| 2025-01-08 17:39:36 +0100 | <merijn> | 2.4 is the version I used at the start of my phd in 2014 |
| 2025-01-08 17:39:24 +0100 | <merijn> | anyway, cabal 2.2 is over a decade old, so :p |
| 2025-01-08 17:38:06 +0100 | <merijn> | sm: At any rate, the core idea is that the semantics of a field will never change for a specific cabal-version, so even if field "foo" changes behaviour in a later version of the spec, any file declaring version X will always use the semantics of 'foo' at time X |
| 2025-01-08 17:36:52 +0100 | <merijn> | ah, right |
| 2025-01-08 17:36:43 +0100 | <tomsmeding> | ah |
| 2025-01-08 17:36:29 +0100 | <tomsmeding> | merijn: the Note here seems to give more certainty https://cabal.readthedocs.io/en/stable/file-format-changelog.html#spec-history |
| 2025-01-08 17:36:27 +0100 | <merijn> | tomsmeding: In general there's no real reason the spec and cabal-install versions should correspond (they always have and do at the moment, but there's no specific reason) |
| 2025-01-08 17:35:48 +0100 | <merijn> | tomsmeding: I'm not 100% it's guaranteed |
| 2025-01-08 17:35:40 +0100 | <tomsmeding> | merijn: "generally"? |
| 2025-01-08 17:35:22 +0100 | <merijn> | sm: to add onto tomsmeding answer, cabal-version refers to the cabal *spec* i.e. supported features, (generally equal to "the earliest cabal version that supports it") |
