 crop | is there a declarative alternative to cargo install? | 10:15:23 |
 @acidbong:envs.net | In reply to @crop_tech:matrix.org
is there a declarative alternative to cargo install? write a recipe with rustPlatform.buildRustPackage and nix build it
except it's not an alternative, it's a Nixpkgs builder exactly for Cargo | 10:21:31 |
| crop | i am trying to build rustfilt with this:
rustfilt = pkgs.rustPlatform.buildRustPackage rec {
pname = "rustfilt";
version = "0.2.1";
src = pkgs.fetchCrate {
inherit pname version;
sha256 = "sha256-Xo6qM2qdzkvoLkOsxksKdpi1rkpBKPGrPxz4zJ3EVyY=";
};
cargoHash = "";
cargoDepsName = pname;
};
but the problem is that the package doesn't contain a cargo lock file
so it fails in fetch-cargo-vendor-util
| 11:26:41 |
| crop | i tried to use the src from github but i now run into this problem: https://github.com/NixOS/nixpkgs/issues/392872 | 12:41:11 |
| crop | ok solved by switching to master and not use the taged version | 12:49:36 |

fetch the crate (or clone the repo), generate the lockfile (cargo generate-lockfile), put the lockfile in your nix config and change cargo* attrs to cargoLock.lockFile = ./Cargo.lock; | 13:06:25 |
 Makuru 📞(WAAF / 4850) | Why does rustc build for me but fenix not? | 15:35:46 |

| Makuru 📞(WAAF / 4850) | Huh? what why? | 15:38:58 |
| Makuru 📞(WAAF / 4850) | Why it starting a non linked but linked bin, from the nix store? | 15:39:27 |
| Makuru 📞(WAAF / 4850) | Why does it work with rustc but not with fenix? | 16:05:10 |
| Makuru 📞(WAAF / 4850) | Where does rustc change stuff? | 16:05:26 |
 dacid44 | How do I manage binaries from crates.io with nix? like, stuff I'd usually install by running cargo install cargo-make | 16:51:26 |
| dacid44 | if it matters, I'm currently using fenix for my Rust toolchain | 16:53:28 |
| dacid44 | also, was cargo-make removed from nixpkgs? I have an old project that pulls it from nixpkgs just fine, but it doesn't appear to exist there anymore | 16:58:16 |
| dacid44 | * also, was cargo-make removed from nixpkgs? I have an old project that pulls it from nixpkgs (24) just fine, but it doesn't appear to exist there anymore | 16:58:27 |
 Ben Sparks | well ideally they'd be packaged in nixpkgs, so just an install like any other | 16:58:32 |
| dacid44 | * also, was cargo-make removed from nixpkgs? I have an old project that pulls it from nixpkgs (24.05) just fine, but it doesn't appear to exist there anymore | 16:58:34 |
| dacid44 | cargo-make seems to have been removed from nixpkgs | 16:59:16 |
| dacid44 | * cargo-make seems to have been removed from nixpkgs? | 16:59:35 |
 ghpzin | Still there on current master, search.nixos.org is just having problems. | 17:01:21 |
| dacid44 | ah. Yeah I just tried it in my home-manager config and it worked | 17:01:40 |
| dacid44 | in general though, how would I do that for something that hasn't been packaged already? Do I have to fully package it myself, or is there a way to just plug in the name on crates.io and maybe a rust toolchain derivation or something and have it be built and installed as if by cargo install? | 17:04:42 |
