| 2025-02-12 22:32:42 +0100 | <lambdabot> | cmccann says: you want a debugger? GHC has one. Except that stepping through lazy evaluation is like listening to a stream of consciousness narrative told by a 5-year-old with ADHD. |

| 2025-02-12 22:32:26 +0100 | <merijn> | really? |
| 2025-02-12 22:32:23 +0100 | <merijn> | aww |
| 2025-02-12 22:32:21 +0100 | <lambdabot> | No quotes match. That's something I cannot allow to happen. |

| 2025-02-12 22:31:51 +0100 | <EvanR> | I will now look up :trace |

| 2025-02-12 22:31:38 +0100 | <geekosaur> | in particular :trace is a thing |
| 2025-02-12 22:31:31 +0100 | <monochrom> | I sympathize with wanting a stepper. But at this stage it looks like you haven't even grokked type inference and instance resolution. |
| 2025-02-12 22:31:12 +0100 | <EvanR> | I write :t something in ghci and see if it 1. works and 2. corresponds with my expectations. It helped |
| 2025-02-12 22:31:11 +0100 | <merijn> | (that is, not affecting build artifacts) |
| 2025-02-12 22:31:03 +0100 | <merijn> | monochrom: so they do, but I'm protecting you and or screwing you (choose as appropriate) by deleting any of your flags I deemed dumb :p |
| 2025-02-12 22:31:02 +0100 | <tomsmeding> | well it's still correct, but now non-sarcastically |
| 2025-02-12 22:30:54 +0100 | <tomsmeding> | oh you added "un" |
| 2025-02-12 22:30:41 +0100 | tomsmeding | nods vigorously |
| 2025-02-12 22:30:34 +0100 | <tomsmeding> | very |
| 2025-02-12 22:30:29 +0100 | <EvanR> | seems to be wildly unpopular |
| 2025-02-12 22:30:19 +0100 | <EvanR> | justsomeguy, ghci has a debugger |

| 2025-02-12 22:30:10 +0100 | <merijn> | monochrom: only the ones I don't explicit remove from you behind your back :p |
| 2025-02-12 22:29:41 +0100 | <monochrom> | I thought flags went into the hash and can trigger rebuild. |
| 2025-02-12 22:29:03 +0100 | <merijn> | still open, sadly, because it was never enough of a problem to invent a solution |

| 2025-02-12 22:28:11 +0100 | <tomsmeding> | justsomeguy: you'll get two different results for the outer and the inner fmap |

| 2025-02-12 22:28:02 +0100 | <merijn> | tomsmeding: I'm ahead of you by 7 years :) |
| 2025-02-12 22:27:59 +0100 | <tomsmeding> | justsomeguy: write down the type of `fmap`; write down the types of the arguments it gets in your expression; match the two and see what the `f` in fmap's type should be |
| 2025-02-12 22:27:46 +0100 | <EvanR> | I reversed the arguments, nevermind me |

| 2025-02-12 22:26:47 +0100 | <tomsmeding> | merijn: I do wonder if just dropping those flags is the right design though; sure, perhaps the user didn't intend to recompile the world, but perhaps they did! |
| 2025-02-12 22:26:45 +0100 | <monochrom> | More than that, you need a tool that tells you what "fmap" resolves to. |

| 2025-02-12 22:26:38 +0100 | <merijn> | tomsmeding: Yes, because cabal-install just invokes the Setup.hs parser |
| 2025-02-12 22:26:32 +0100 | <justsomeguy> | Maybe a haskell debugger? |
| 2025-02-12 22:26:12 +0100 | <justsomeguy> | Is there some tool I can put this into and see the evaluation process step-by-step? |
