| 2026-03-03 16:48:55 +0100 | <haskellbridge> | <ijouw> Yes, (:) is the constructor for lists. You need the one for trees. |

| 2026-03-03 16:48:05 +0100 | <c_wraith> | Do you have a specific example to work with, or just exploring the idea more generally? |
| 2026-03-03 16:46:14 +0100 | <c_wraith> | So you should be starting with the data definition, and the constructors within |
| 2026-03-03 16:46:00 +0100 | <c_wraith> | Ah, true. Matching is done against the constructors for the data type. |
| 2026-03-03 16:45:28 +0100 | <durstloescher> | my intuition says i just use (x:xs) but trees are no lists |
| 2026-03-03 16:45:07 +0100 | <durstloescher> | i don't understand how i can "get" the value and how to proceed with the next node |
| 2026-03-03 16:44:39 +0100 | <durstloescher> | i know the concept but i'm not comfortable with the use of pattern matching in this topic |
| 2026-03-03 16:43:28 +0100 | <c_wraith> | (There's nothing particularly special about Haskell for binary trees, at least in the context of immutable data structures.) |
| 2026-03-03 16:42:24 +0100 | <c_wraith> | How comfortable are you with binary trees in general? |
| 2026-03-03 16:41:56 +0100 | <durstloescher> | hey can someone explain binary trees in haskell to me? |

| 2026-03-03 16:16:11 +0100 | gentauro | however, I DO run my `ghci` with stack -> `stack ghci` |
| 2026-03-03 16:15:47 +0100 | <gentauro> | kind of strainge tbh |
| 2026-03-03 16:15:43 +0100 | <gentauro> | __monty__: Nope. That seem to work |

| 2026-03-03 16:12:08 +0100 | <__monty__> | Can you reproduce the same behavior in GHCi? |
| 2026-03-03 16:11:18 +0100 | <gentauro> | but, I'm not on a windows device … |
| 2026-03-03 16:11:10 +0100 | <gentauro> | I guess even (Elm) Evan ran into something like this (back in 2019): https://discourse.elm-lang.org/t/help-improve-unicode-support-on-windows/3366 |
| 2026-03-03 16:11:05 +0100 | <lambdabot> | print x = putStrLn (show x) |
| 2026-03-03 16:11:05 +0100 | <int-e> | @src print |
| 2026-03-03 16:09:47 +0100 | <gentauro> | __monty__: yeah: `putStr (show localeEncoding)` -> `UTF-8` |
| 2026-03-03 16:07:31 +0100 | <__monty__> | Does System.IO.localeEncoding report UTF-8 for you? |

| 2026-03-03 16:05:47 +0100 | <__monty__> | s/en_US/en_DK/g; except LC_ALL is empty. |
| 2026-03-03 16:04:37 +0100 | <gentauro> | __monty__: what does your `locale` say? |
| 2026-03-03 15:59:17 +0100 | <__monty__> | If I `hSetEncoding` to `latin1` I do get the error you got so it looks like it is an encoding problem. |
| 2026-03-03 15:55:32 +0100 | <gentauro> | it's correct to assume that `hSetEncoding` is set globally right? I just need to add it in my `main :: IO ()` right? |

| 2026-03-03 15:53:23 +0100 | <gentauro> | it's just x3 the same syntas with the following keywords |
| 2026-03-03 15:53:07 +0100 | <gentauro> | __monty__: obviously not. It's to write less ;) |
| 2026-03-03 15:51:56 +0100 | wbrawner | (~wbrawner@129.146.105.153) (Ping timeout: 252 seconds) |
| 2026-03-03 15:51:55 +0100 | <__monty__> | That doesn't look like valid Haskell syntax. |
| 2026-03-03 15:51:27 +0100 | <gentauro> | just in case, it's `hSetEncoding {stderr|stdin|stdout} utf8` |
| 2026-03-03 15:51:19 +0100 | misterfish | (~misterfis@84.53.85.146) (Ping timeout: 264 seconds) |
| 2026-03-03 15:50:25 +0100 | <gentauro> | I guess I've set UTF-8 properly in the Haskell app. |
| 2026-03-03 15:50:10 +0100 | <gentauro> | ijouw: `hGetEncoding` -> `Just UTF-8` |
| 2026-03-03 15:47:46 +0100 | <gentauro> | ijouw: let me try |
| 2026-03-03 15:47:05 +0100 | <yahb2> | 🍎🍏 |
| 2026-03-03 15:47:05 +0100 | <gentauro> | % putStrLn [ '🍎', '🍏' ] |
| 2026-03-03 15:46:57 +0100 | <__monty__> | (FYI, you can use en_DK to get sensible dates ; ) ) |
| 2026-03-03 15:46:40 +0100 | <haskellbridge> | <ijouw> Just to be sure, you can use hGetEncoding to double check |
