| 2021-03-19 11:04:13 | <dramforever> | For Haskell *development* just stay away from Arch Haskell packages. Actually, for most cases, as a rule of thumb for *any* development just stay away from *any* Linux distro packages. |
| 2021-03-19 11:04:31 | <dramforever> | (If you'd like to disagree, you clearly know enough to ignore my rule of thumb.) |
| 2021-03-19 11:05:34 | <__monty__> | Gentoo and NixOS don't have this problem : ) Even on Debian you might want to use their packages because a significant install base is going to be using those versions anyway. |

| 2021-03-19 11:08:51 | <dramforever> | My main gripe about the distro libraries is that they are often built for the programs included in the distro |
| 2021-03-19 11:09:13 | <dramforever> | e.g. Having pandoc means including pandoc dependencies |

| 2021-03-19 11:09:54 | <yushyin> | as a maintainer i wouldn't even bother maintaining haskell packages. build some well known haskell packages (pandoc,shellcheck) statically, ignore libraries and recommend ghc/stack/nix for development |

| 2021-03-19 11:10:03 | <dramforever> | Developing on them, and one day you'll get a missing dependency, the next day you'll get an outdated library, and the next you'll be missing a dependency, whose dependency is newer than that in the distro and conflicts with something |
| 2021-03-19 11:10:25 | <__monty__> | It's less of an issue in source-based distros. NixOS makes all of hackage available for example. |
| 2021-03-19 11:10:27 | <dramforever> | yushyin: Not being able to build a package in a distro with your distro's packages sound... a bit odd :( |
| 2021-03-19 11:10:40 | <dramforever> | __monty__: They still get outdated easily :( |
| 2021-03-19 11:11:35 | <__monty__> | Potato, tomato, outdated, stable. |
| 2021-03-19 11:12:05 | <dramforever> | As if nixpkgs haskell packages are, by any standard, stable |
| 2021-03-19 11:12:24 | <__monty__> | Most of them derive from stackage LTS. |
| 2021-03-19 11:12:36 | <dramforever> | That's true |
| 2021-03-19 11:12:50 | <dramforever> | I guess somehow I just keep using non-stackage stuff :P |

| 2021-03-19 11:13:38 | <dramforever> | I guess I don't get to complain about a set of stuff being unstable if it's literally the entire hackage |

| 2021-03-19 11:16:28 | <jonn> | Dear all, I want to add a flag to my own project for conditional compilation. Sadly, I'm yet to switch to cabal v2 and am still using stackage. How do I do that without manually patching .cabal file (which I suppose is generated from packages.yaml + stack.yaml?) |

| 2021-03-19 11:18:14 | <[exa]> | jonn: I'm afraid switching to cabal v2 might be easier |
| 2021-03-19 11:18:36 | <dramforever> | You don't have to use package.yaml for using stack. If you don't have a package.yaml, that .cabal file will be used. |
| 2021-03-19 11:18:48 | <opqdonut> | yeah, I use stack.yaml + myproj.cabal |
| 2021-03-19 11:18:57 | <dramforever> | And I think hpack (package.yaml thing) and stack support flags too? |

| 2021-03-19 11:19:28 | <jonn> | It does, but it only seem to support flags for dependencies, not the project apps / libs. |
| 2021-03-19 11:20:01 | <jonn> | At least, that's what I gathered from reading the docs and observations... |

| 2021-03-19 11:20:15 | <day> | __monty__: ive seen nixOS mentionings pop up more and more. maybe i'll give it a try, but I kind of like the rolling release style |
| 2021-03-19 11:20:17 | <dramforever> | By 'it' do you mean hpack or stack? |
| 2021-03-19 11:20:27 | <jonn> | stack, whilst reading package.yaml |
| 2021-03-19 11:20:49 | <__monty__> | day: NixOS unstable is a rolling release. |
| 2021-03-19 11:20:59 | <day> | oh |
| 2021-03-19 11:21:07 | <jonn> | Ok, so I'll try to edit .cabal file and hope that stack shan't regenerate it. |
| 2021-03-19 11:21:23 | <dramforever> | If you delete package.yaml it will, but how will that help? |
| 2021-03-19 11:21:25 | <__monty__> | There's minimal checks ensuring the channel builds which can hold up channel bumps. |
| 2021-03-19 11:21:35 | <dramforever> | Oh no https://github.com/sol/hpack#flags |
| 2021-03-19 11:21:44 | <dramforever> | This is some confusing documentation |
| 2021-03-19 11:21:59 | <dramforever> | jonn: But from what I gather, you *can* specify flags in package.yaml |

| 2021-03-19 11:24:05 | <dramforever> | Yeah that's why I was asking, you keep mentioning stack not supporting flags and mention package.yaml vs *.cabal, but they are kind of two separate things |

| 2021-03-19 11:25:07 | <dramforever> | I'm going to guess that using the name for your local package will make it apply to your local package |

| 2021-03-19 11:28:01 | <jonn> | But maybe it does... |
| 2021-03-19 11:28:16 | <dramforever> | If you use NixOS you also get a really different system configuration thing |

| 2021-03-19 11:29:31 | <__monty__> | day: The package manager is usable everywhere. The special thing about NixOS is declarative system configuration through NixOS modules (kind of a bad name but hysterical raisins). |
| 2021-03-19 11:29:45 | <dramforever> | jonn: Yeah, the reason you need to tell the two apart is because if you don't like hpack, you can just delete package.yaml and edit *.cabal, as mentioned earlier |
