## Available Utilities
|
||||
|
||||
### nixfetch (WIP)
|
||||
### 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
|
||||
|
||||
```bash
|
||||
$ 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, and common functions
|
||||
should go under the `commons` workspace.

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](https://github.com/viperml/nh) project. If you wish to add
|
||||
an utility, feel free to.
|
||||
an utility, feel free to. Format your code with `rustfmt`, leave proper comments.
