## Nix Flakes and Classic Nix ## Nix Flakes and Classic Nix
> Currently the New CLI is strongly bound to the Flakes feature, so I will use the term "Flakes" to refer to the New CLI & Flakes feature in this book.
Since the `nix-command` and `flakes` features are still experimental, the official documentation lacks detailed coverage, and the community's documentation on them is also scattered. From the perspective of reproducibility, ease of management, and maintenance, the classic Nix package structure and CLI are no longer recommended. Therefore, I will not delve into the usage of classic Nix. Beginners are advised to start with `nix-command` and `flakes` while disregarding any content related to classic Nix.

> 当前 New CLI 与 Flakes 特性是强绑定的（虽然现在已经有明确的拆分计划），因此在本书中我会使用 Flakes 来指代 New CLI 与 Flakes 两项特性。
Nix 于 2020 年推出了 `nix-command` & `flakes` 两个新特性，它们提供了全新的命令行工具、标准的 Nix 包结构定义、类似 cargo/npm 的 `flake.lock` 版本锁文件等等。这两个特性极大地增强了 Nix 的能力，因此虽然至今（2023/5/5）它们仍然是实验性特性，但是已经被 Nix 社区广泛使用。 Nix 于 2020 年推出了 `nix-command` & `flakes` 两个新特性，它们提供了全新的命令行工具、标准的 Nix 包结构定义、类似 cargo/npm 的 `flake.lock` 版本锁文件等等。这两个特性极大地增强了 Nix 的能力，因此虽然至今（2023/5/5）它们仍然是实验性特性，但是已经被 Nix 社区广泛使用。
但由于 `nix-command` & `flakes` 仍然是实验性特性，官方文档基本不包含任何介绍它们的内容，同时社区关于 Flakes 的文档也相当分散且不完整。 但由于 `nix-command` & `flakes` 仍然是实验性特性，官方文档基本不包含任何介绍它们的内容，同时社区关于 Flakes 的文档也相当分散且不完整。
