nutils

Utils so good, they make you nut A collection of utilities for the Nix package manager

Available Utilities

nixfetch [0.1.0]

nixfetch fetches a file, adds it to the nix store and returns JSON data for the newly added path: mainly the file path and the hash. It is ultimately a wrapper around nix store prefetch-file. The nix store is used to avoid storing duplicates of the same file.

Usage

$ nixfetch https://raw.githubusercontent.com/NotAShelf/nutils/main/LICENSE # e.g.: try to fetch a path from Github
{"hash":"sha256-OXLcl0T2SZ8Pmy2/dmlvKuetivmyPd5m1q+Gyd+zaYY=","storePath":"/nix/store/zgw1a0w4j9anca8kjmgizy1m5zc9c0k2-LICENSE"}

flakecheck [0.1.0] (WIP)

flakecheck runs nix flake check with the --no-build argument and monitors the output for file errors containing the message is not valid. If a broken path is found, then attempts to repair the given path with nix-store --repair-path.

This is not a magic bullet. You should be concerned if your store produces broken paths, and investigate carefully.

Building

You know how to use Rust, yes?

Build the workspace you'd like to use. Nix package is a TODO because I don't really know how to build a multi-workspace project with Nix.

Contributing

Do you know how to use Rust? I don't. Make a pull request if you find one of my many mistakes. You may unlock the golden shelf skin at 99 mistakes found.

The repository follows a very simple structure: each utility must be its own workspace. If you find yourself repeating code, start abstracting or add a commons workspace.

Adding new utilities

This is a monorepo for utility wrappers around the nix package manager, focusing on the package manager itself rather than nixos-rebuild unlike the awesome nh project. If you wish to add an utility, feel free to. Format your code with rustfmt, leave proper comments.
