| 2025-02-12 01:48:37 +0100 | <Leary> | kaol: If your ghc is recent enough, you have "multi-repl"; you can list multiple components or just do `cabal repl all`. For older GHC and ghciwatch, which don't support it, there's a nice way to write your cabal file such that you have a `dev` component that effectively combines the others without interfering with them: https://gist.github.com/LSLeary/6551f1dc3e25fe0d0d629b4ddb385359 |

| 2025-02-12 01:17:58 +0100 | <EvanR> | an extreme example of manually passing a dictionary, but it's pretty doable for 1 string |
| 2025-02-12 01:17:13 +0100 | <EvanR> | just pass the string form (lazily perhaps, if you might not use it) |
| 2025-02-12 01:16:55 +0100 | <EvanR> | like most examples of trying to save or restore Show instances |
| 2025-02-12 01:16:42 +0100 | <EvanR> | the example of forall a . Show a => being inflexible, this would be much better just as "pass in a string instead of using a constraint" |

| 2025-02-12 01:15:28 +0100 | <EvanR> | I just ignore Show and wish that the interactive interpreter could just show anything without any code or deriving, and this one off feature |
| 2025-02-12 01:15:12 +0100 | <dminuoso> | Im not convinced calling those instances "bad" is sensible at this point. |
| 2025-02-12 01:15:04 +0100 | <ski> | yes. i see no reason to abandon that vision, still |
| 2025-02-12 01:14:43 +0100 | <dminuoso> | ski: That was the original intent some decades ago. The reality of hackage tells a different story. |
| 2025-02-12 01:14:32 +0100 | <EvanR> | and if there's a better tool we can invent that other tool |
| 2025-02-12 01:14:14 +0100 | <EvanR> | for other purposes it might not be the best tool |
| 2025-02-12 01:14:10 +0100 | <ski> | (`Show' and `Read' are not for custom formatting. the instances on different types are meant to play together (`instance Show a => Show (Maybe a)',&c.). this, imho means that if your instance doesn't use valid Haskell source code format (either data constructors, or exported abstract operations), your instance is bad) |
| 2025-02-12 01:13:46 +0100 | <EvanR> | the cases for which it was invented, it really shines there |
| 2025-02-12 01:12:56 +0100 | <EvanR> | if it just didn't have type classes |
| 2025-02-12 01:12:47 +0100 | <EvanR> | haskell would be much more of a pain in the ass without it though |
| 2025-02-12 01:12:30 +0100 | <dminuoso> | typeclasses certainly are not the reason Im using Haskell. |

| 2025-02-12 01:12:01 +0100 | <EvanR> | it's not a good thing to base the entire type class system, or break the whole system over |
| 2025-02-12 01:11:49 +0100 | <dminuoso> | Since you are forced to do one of them, authors will just do - and they dont agree. |
| 2025-02-12 01:11:46 +0100 | <EvanR> | Show is stupid for other reasons |

| 2025-02-12 01:11:33 +0100 | <dminuoso> | It's a matter of not having the choice. |
| 2025-02-12 01:11:32 +0100 | <EvanR> | that's like every other language, they never got to the point of having solid abstractions because they felt it was necessary to shoehorn stuff and hammer a screw with it |
| 2025-02-12 01:11:28 +0100 | <dminuoso> | When you have only a single typeclass for "turn this thing into human text" that widely exists, but there's this large mismatch between "produce some nice legible string" and "produce valid haskell expressions"... |
| 2025-02-12 01:10:58 +0100 | <EvanR> | if the solid abstraction isn't doing what you want, the answer is probably not to break the abstraction for everyone, just don't use this abstraction |

| 2025-02-12 01:10:34 +0100 | <dminuoso> | I think its quite related. |
| 2025-02-12 01:10:30 +0100 | <EvanR> | anyway solid abstractions that are actually solid is great as long as you can do what you need to do with it |
| 2025-02-12 01:09:38 +0100 | <EvanR> | but Show type issues are a separate ergonomic issue from type class mechanisms I think |
| 2025-02-12 01:09:05 +0100 | <EvanR> | yeah I have dumb newtypes specifically to change the show instance |
| 2025-02-12 01:09:00 +0100 | <dminuoso> | So dunno, feels like incoherence is already upon us,. |
| 2025-02-12 01:08:43 +0100 | <dminuoso> | Or `newtype SortAfterShow ...` |
| 2025-02-12 01:08:33 +0100 | <dminuoso> | Say `newtype UppercaseShow ...` |
| 2025-02-12 01:08:26 +0100 | <dminuoso> | Or well, except for those versions that do silly things |
