 sterni (he/him) | I’ll just see to it that hugs gets propagated quickly to the branch after megre | 22:58:29 |
 Alex | Ok, thanks. | 22:58:50 |

 bglgwyng | Do you mean a bug in builtins.functionArgs? | 00:08:45 |
| bglgwyng | https://github.com/bglgwyng/nix-x-cabal
I wrote another Nix + Haskell framework. It is based on flake-parts and uses plan.json to reproducible builds. It delegates all the network access from Cabal to Nix, and runs cabal build in pure way. | 04:59:21 |
| bglgwyng | It doesn't use pre-baked package set, but resolves version constraints. So you can freely choose any version of ghc(at this moment, in nixpgks.haskell.packages.ghc***) | 05:00:45 |
| bglgwyng | I wish I could provide the docs right now, but nix-options-doc and flake-parts don't play well together for some reasons.. | 05:10:06 |

(Was looking through wondering whether you're using IFD.) | 07:17:46 |
| bglgwyng | Thanks! | 07:19:13 |
| bglgwyng | No I don't use IFD | 07:19:16 |
| Alex | Are you sure? It looks to me like you do...
https://github.com/bglgwyng/nix-x-cabal/blob/4c7136218ba15da9304a054fbaeb8641db5592c3/modules/cabal-project.nix#L118
Or maybe I am mistaken and using builtins.readFile on an output is not IFD? | 07:20:28 |
| bglgwyng | ah... callCabal2Nix might use IFD internally | 07:20:35 |

ah... callCabal2Nix might use IFD internally That does too IIRC. | 07:20:51 |
| bglgwyng | Is readJSON (readFile ...) also considred IFD? | 07:21:10 |
| bglgwyng | I thought that import in IFD means the usage of `import' keyword | 07:21:40 |
 Wolfgang Walther | If the file is an output of another derivation, then yes. See https://nix.dev/manual/nix/2.30/language/import-from-derivation. | 07:22:08 |
| bglgwyng | I think I can remove the usage of callCabal2nix and it's in the roadmap | 07:22:18 |
| Alex | I guess disabling IFD with --option is one way of being sure. | 07:22:19 |
 MangoIV | it's every time where you have an output and you reflect whatever that output contains back into the evaluation phase | 07:22:48 |
| bglgwyng | I see | 07:24:03 |
