2024-11-01 10:27:16 +0100 | <tomsmeding> | my experience with this stuff is that IO seems to be strict in all your tests, but it fails if you actually want to use that for code correctness |
2024-11-01 10:27:19 +0100 | <tomsmeding> | so use evaluate and be safe |
2024-11-01 10:34:05 +0100 | <c_wraith> | evaluate isn't magic. the documentation explains what does and why. |
2024-11-01 10:35:43 +0100 | <tomsmeding> | right. In practice, though, not using `evaluate` comes to bite me not in the presence of exceptions but when benchmarking |
2024-11-01 10:36:10 +0100 | <tomsmeding> | if you want to benchmark an IO operation and are doing the timing manually for some reason, please, use `evaluate`. Using `return $! _` or something similar _will not work properly_ |

2024-11-01 11:25:37 +0100 | <mauke> | why without creating a binding? |
2024-11-01 11:25:38 +0100 | <tomsmeding> | you can create the binding locally |
2024-11-01 11:25:46 +0100 | <tomsmeding> | `let ?param = _ in f x y z` |

2024-11-01 12:15:11 +0100 | <sprotte24> | Hi |
2024-11-01 12:15:21 +0100 | <Rembane> | Hi sprotte24 ! |
2024-11-01 12:15:35 +0100 | <sprotte24> | I want to write a Haskell program |
2024-11-01 12:15:47 +0100 | <sprotte24> | Hi, Rembane |
2024-11-01 12:15:51 +0100 | <mauke> | what's it do? |
2024-11-01 12:16:19 +0100 | <Hecate> | rembaaaaaaane |
2024-11-01 12:16:25 +0100 | <Hecate> | what's uuuuup |
2024-11-01 12:16:28 +0100 | <sprotte24> | The Haskell programm has to compute the nearest Power of two for a given n. |
2024-11-01 12:16:34 +0100 | <Hecate> | sprotte24: nice |
2024-11-01 12:16:37 +0100 | <sprotte24> | Example: |
2024-11-01 12:16:42 +0100 | <mauke> | oh, is this homework? |
2024-11-01 12:17:21 +0100 | <sprotte24> | n= 9 nearest Power is 16 |
2024-11-01 12:17:35 +0100 | <mauke> | I'd say it's 8 |
2024-11-01 12:17:41 +0100 | <sprotte24> | Yes. kome work |
2024-11-01 12:18:03 +0100 | <Hecate> | mauke: maybe they have to round to the highest power of 2 |
2024-11-01 12:18:15 +0100 | <mauke> | yeah, that actually makes things easier |
2024-11-01 12:18:22 +0100 | <Rembane> | Hecate: Suuuuuuuuuuuuuuuuuup! :D |
2024-11-01 12:18:23 +0100 | <sprotte24> | The restriction: using binary is forbidden. |
2024-11-01 12:18:33 +0100 | <mauke> | define "using binary" |
2024-11-01 12:18:38 +0100 | <mauke> | like bit shifts? |
2024-11-01 12:18:46 +0100 | <Hecate> | damnit I was about to suggest that hahahaha |
2024-11-01 12:19:23 +0100 | <Hecate> | Rembane: I'm not doing too bad! Still at Chalmers? |
2024-11-01 12:20:15 +0100 | <sprotte24> | ok. if I use binary number, the Powers of 2 have the format 1, 10 100 1000 and so on |
2024-11-01 12:20:20 +0100 | <mauke> | :t head . dropWhile (< ?n) . iterate (2 *) $ 1 |
2024-11-01 12:20:21 +0100 | <lambdabot> | (Ord c, ?n::c, Num c) => c |
2024-11-01 12:20:29 +0100 | <Rembane> | Hecate: Still at Chalmers! I'll be done any day now. :D |
2024-11-01 12:21:21 +0100 | <sprotte24> | I am not allowed to use a list |
2024-11-01 12:21:33 +0100 | <Hecate> | Rembane: lovely. :) Say hi to Andreas Abel from me if you meet him |
2024-11-01 12:21:45 +0100 | <Rembane> | Hecate: Sure thing! :D |

2024-11-01 12:25:44 +0100 | <sprotte24> | I plan to build an recursive solution? |
2024-11-01 12:26:15 +0100 | <mauke> | yeah, if you want to emulate a loop in functional code, it's always going to be a recursive function |
2024-11-01 12:26:32 +0100 | <mauke> | (or a data structure like a list, but you're not allowed to do that, apparently) |

2024-11-01 14:01:37 +0100 | <tomsmeding> | Square: you might want to steal stuff from how head.hackage is implemented https://ghc.gitlab.haskell.org/head.hackage/ |
2024-11-01 14:05:01 +0100 | <Leary> | Square: https://hackage.haskell.org/ says "Hackage-server is on github [...]. Developer documentation is on in the github README, includig a quick guide to running your own server instance, and mirroring the central server." |

2024-11-01 14:30:47 +0100 | <merijn> | mauke: Cabal just invokes GHC on C files, which determines what C compiler to call |
2024-11-01 14:30:58 +0100 | <merijn> | I think there was either a config file or GHC flag to tell it to use something else |
2024-11-01 14:31:01 +0100 | <mauke> | no, cabal is doing something stupid |
2024-11-01 14:31:05 +0100 | <mauke> | and I can't figure out what |
2024-11-01 14:31:13 +0100 | <yushyin> | 4345 is the missing deps on foreign libs error, no? this is one of the more murky errors |
2024-11-01 14:31:35 +0100 | <merijn> | mauke: Error? And I assume you mean actual C and not secretly C++? |
2024-11-01 14:31:46 +0100 | <mauke> | Missing (or bad) header file: wcalc.h |
2024-11-01 14:32:01 +0100 | <mauke> | the fun part is that it only happens on 'cabal install'. 'cabal build' is fine with it |
2024-11-01 14:32:09 +0100 | <merijn> | mauke: Ah, that sounds more like wrong include dirs than wrong compiler, no? |
2024-11-01 14:32:20 +0100 | <mauke> | oh, the compiler is fine |
2024-11-01 14:32:33 +0100 | <merijn> | mauke: Is the cabal file public? |
2024-11-01 14:32:44 +0100 | <mauke> | but I can't get it to tell me wtf it's doing, so my plan is to configure a fake compiler that just dumps what's going on |
2024-11-01 14:32:52 +0100 | <merijn> | ooh |
2024-11-01 14:32:57 +0100 | <merijn> | I think I know :D |
2024-11-01 14:33:05 +0100 | <merijn> | But lemme check the cabal file first |

2024-11-01 14:33:53 +0100 | <merijn> | mauke: First clue is: "build works, install fails". install *always* builds an sdist *first* and THEN installs from that. To protect against broken sdists |
2024-11-01 14:34:05 +0100 | <merijn> | mauke: So most likely your sdist is fucked and not including the header |
2024-11-01 14:34:29 +0100 | <mauke> | I wish it would stop building an sdist. all I want is an executable |
2024-11-01 14:35:06 +0100 | <merijn> | mauke: Yeah, I think the problem is that `includes` doesn't include your headers in the sdist |
2024-11-01 14:35:21 +0100 | <merijn> | mauke: My C shipping projects explicitly list headers under `extra-source-files` |

2024-11-01 14:36:28 +0100 | <merijn> | C-sources get included, `includes` does not (since it might contain generated/system/whatever stuff) |
