Message definition (Flakes)

=== Nix configuration ===
It is possible to override the global Nix configuration set in your <code>nix.conf</code> file for the purposes of evaluating a flake. This can be useful, for example, for setting up binary caches specific to certain projects, while keeping the global configuration untouched. The flake file can contain a nixConfig attribute with any relevant configuration settings supplied. For example, enabling the nix-community binary cache would be achieved by:
{{File|3=<nowiki>{
...
nixConfig = {
   extra-substituters = [
   "https://nix-community.cachix.org"
   ];
   extra-trusted-public-keys = [
   "nix-community.cachix.org-1:...="
   ];
}
}</nowiki>|name=flake.nix|lang=nix}}{{Note|If you are used to configuring your Nix settings via the NixOS configuration, these options are under <code>nix.settings</code> and not <code>nix</code>. For example, you cannot specify the automatic storage optimisation under <code>nix.optimisation.enable</code>.}}

Nix 配置

为了推导 flake，您可以覆盖 nix.conf 文件中设置的全局 Nix 配置。例如，这可用于设置特定项目的二进制缓存源，同时保持全局配置不变。Flake 文件中可包含一个 nixConfig 属性，并在其中设置相关配置。例如，启用 nix-community 二进制缓存可以通过以下方式实现：

❄︎ flake.nix

{
  ...
  nixConfig = {
    extra-substituters = [
      "https://nix-community.cachix.org"
    ];
    extra-trusted-public-keys = [
      "nix-community.cachix.org-1:...="
    ];
  }
}

Note: 如果您习惯通过 NixOS 配置来设置 Nix 配置，则这些选项位于 nix.settings 下，而不是 nix 下。例如，您无法在 nix.optimization.enable 下指定自动存储优化。
