| 2025-01-11 22:53:58 +0100 | <c_wraith> | there are anti-patterns in Haskell. Things like the existential typeclass pattern, which laziness turns out to be a much simpler solution to in nearly every case. |

| 2025-01-11 22:45:23 +0100 | <ash3en> | i did use them in the past already, but I often am too afraid to use anti-patterns I am not aware of |

| 2025-01-11 22:43:13 +0100 | <geekosaur> | you'll get used to HOFs eventually 🙂 |
| 2025-01-11 22:42:03 +0100 | <ash3en> | geekosaur: yes, thank you. i will keep it like this for now and maybe put them into a single function later on : ) |
| 2025-01-11 22:41:32 +0100 | <tomsmeding> | I think I'm going to stay with a helper function. :) |

| 2025-01-11 22:40:46 +0100 | <geekosaur> | ash3en, that works. I think you should also be able to write tokenizeNumber in terms of tokenizeString though |
| 2025-01-11 22:40:41 +0100 | <tomsmeding> | the tail blows up but the zipWith doesn't evaluate the tail on [] |
| 2025-01-11 22:40:02 +0100 | <tomsmeding> | probie: I did not |
| 2025-01-11 22:39:58 +0100 | <tomsmeding> | oh the zipWith saves you here, cute |
| 2025-01-11 22:39:44 +0100 | <lambdabot> | True |
| 2025-01-11 22:39:43 +0100 | <tomsmeding> | > (and . (zipWith (==) <*> tail)) [] |
| 2025-01-11 22:39:41 +0100 | <probie> | You didn't specify that you wanted it to be readable |
| 2025-01-11 22:39:24 +0100 | <tomsmeding> | ah yes I can read that |

| 2025-01-11 22:37:29 +0100 | <ash3en> | geekosaur: this is what i did now. does it look good to you? https://paste.tomsmeding.com/WfD77OU3 |
| 2025-01-11 22:32:39 +0100 | <tomsmeding> | i.e. "allEqual" |
| 2025-01-11 22:32:30 +0100 | <tomsmeding> | is there a shorter way to write (\case [] -> True ; x:xs -> all (== x) xs) |

| 2025-01-11 22:20:12 +0100 | <ash3en> | i think i get it now and i will try it out |
| 2025-01-11 22:18:29 +0100 | <ncf> | monochrom: i'm still curious. how do you prove the obvious free theorem for forall a b. b -> ((a -> a) -> b) -> b ? |
| 2025-01-11 22:17:58 +0100 | <geekosaur> | you can put any Haskell code inside the braces, and as long as the type of rtToken is available (since it's generating a normal Haskell source file and not using TH, it will be) you can use it |

| 2025-01-11 22:16:38 +0100 | <geekosaur> | why wouldn't that work? |

| 2025-01-11 22:14:51 +0100 | <ash3en> | this probably won't work, but im not sure, since the functions are called using Alex like this: |

| 2025-01-11 22:12:19 +0100 | <geekosaur> | so tokenizeAddressPattern becomes tokenize AddrPattern, tokenizeInt becomes tokenize (Integer . read . BS.unpack), etc. |
| 2025-01-11 22:11:34 +0100 | <geekosaur> | you can make one "master function" with wrappers for the specific uses, unless you want to pass the extra HOF at use sites. you pass a function (Text -> <whatever type rtToken is>) |

| 2025-01-11 22:08:19 +0100 | <ash3en> | i'm still not sure how i'd make a single function out of these. |

| 2025-01-11 22:06:21 +0100 | <geekosaur> | it could be even simpler but you need to apply more than just the constructor sometimes (e.g. Integer) |
