| 2025-11-25 22:47:58 +0100 | <hseg> | hrmph. I broke something |
| 2025-11-25 22:47:12 +0100 | <hseg> | now to see if my patch actually fixed things... |
| 2025-11-25 22:47:01 +0100 | <hseg> | well, this bit |
| 2025-11-25 22:46:55 +0100 | <hseg> | it builds ! |

| 2025-11-25 22:25:04 +0100 | <hseg> | ... ah, that's why you wrote fmap .. $ and not <$> -- precedence |
| 2025-11-25 22:21:52 +0100 | <hseg> | (probably because there are some differences between what I pasted and what I wrote) |

| 2025-11-25 22:21:29 +0100 | <hseg> | ... for some reason it's not working when I paste it into the actual code -- ghc doesn't think this typechecks? |
| 2025-11-25 22:21:09 +0100 | <tomsmeding> | I very rarely use MaybeT so I also had to double-check that it does the right thing |

| 2025-11-25 22:10:34 +0100 | <hseg> | it's been a while, am a little rusty |
| 2025-11-25 22:10:31 +0100 | <tomsmeding> | (because it chooses based on the Maybe, not based on monadic state in m) |
| 2025-11-25 22:10:19 +0100 | <hseg> | ah, excellent |
| 2025-11-25 22:10:01 +0100 | <tomsmeding> | but 'MaybeT m' is Alternative regardless of m, as long as m implements Monad |
| 2025-11-25 22:09:49 +0100 | <tomsmeding> | yes |
| 2025-11-25 22:09:43 +0100 | <hseg> | on MaybeT IO? |
| 2025-11-25 22:09:06 +0100 | <tomsmeding> | this asum uses <|> on MaybeT |
| 2025-11-25 22:08:42 +0100 | <tomsmeding> | Leary: hseg: like this? https://play.haskell.org/saved/C0K0rs9c |
| 2025-11-25 22:07:46 +0100 | <hseg> | problem. Shake.Action is not an Alternative |
| 2025-11-25 22:07:34 +0100 | <[exa]> | but no need for transformers |
| 2025-11-25 22:07:10 +0100 | merijn | (~merijn@host-vr.cgnat-g.v4.dfn.nl) merijn |
| 2025-11-25 22:07:09 +0100 | <[exa]> | yeah it feels dirty |
| 2025-11-25 22:06:03 +0100 | <[exa]> | (IO is Alternative) |
| 2025-11-25 22:06:00 +0100 | <tomsmeding> | doing it with IO exceptions feels ugly |
| 2025-11-25 22:05:37 +0100 | <[exa]> | it crashes but <|> saves |
| 2025-11-25 22:05:28 +0100 | <hseg> | wait, won't Just env <- getEnv crash if the envvar is unset? |
| 2025-11-25 22:05:05 +0100 | <[exa]> | (otoh yeah MaybeT is the clean way) |
| 2025-11-25 22:04:50 +0100 | <[exa]> | in IO you can just bind to `Just env <- getEnv` and return the env in 2 alternatives, no need to do MaybeT |
| 2025-11-25 22:04:35 +0100 | <hseg> | am getting a little confused with the tower of monads I'm using here |
| 2025-11-25 22:04:23 +0100 | <tomsmeding> | yes and then end with `maybe default return =<<` |

| 2025-11-25 22:03:01 +0100 | <Leary> | Rather, `<|>` on `MaybeT IO`. |
| 2025-11-25 22:02:57 +0100 | <tomsmeding> | so what about the IO |
| 2025-11-25 22:02:52 +0100 | <hseg> | Maybe |
| 2025-11-25 22:02:46 +0100 | <tomsmeding> | what's f here? |
| 2025-11-25 22:02:42 +0100 | <lambdabot> | (Foldable t, Alternative f) => t (f a) -> f a |
