# Description

`nix fmt` calls the formatter specified in the flake.

Flags can be forwarded to the formatter by using `--` followed by the flags.

Any arguments will be forwarded to the formatter. Typically these are the files to format.


# Example

To use the [official Nix formatter](https://github.com/NixOS/nixfmt):

```nix
# flake.nix
{
  outputs = { nixpkgs, self }: {
    formatter.x86_64-linux = nixpkgs.legacyPackages.${system}.nixfmt-tree;
  };
}
```
