Name

nix flake init - create a flake in the current directory from a template

Synopsis

nix flake init [option...]

Examples

Create a flake using the default template:
```
# nix flake init
```
List available templates:
```
# nix flake show templates
```

Create a flake from a specific template:

# nix flake init -t templates#simpleContainer

Description

This command creates a flake in the current directory by copying the files of a template. It will not overwrite existing files. The default template is templates#defaultTemplate, but this can be overridden using -t.

Template definitions

A flake can declare templates through its templates and defaultTemplate output attributes. A template has two attributes:

description: A one-line description of the template, in CommonMark syntax.
path: The path of the directory to be copied.

Here is an example:

outputs = { self }: {

  templates.rust = {
    path = ./rust;
    description = "A simple Rust/Cargo project";
  };

  templates.defaultTemplate = self.templates.rust;
}

Options

--template / -t template
The template to use.

Common evaluation options:

--arg name expr
Pass the value expr as the argument name to Nix functions.
--argstr name string
Pass the string string as the argument name to Nix functions.
--eval-store store-url
The Nix store to use for evaluations.
--impure

--include / -I path
Add path to the list of locations used to look up <...> file names.
--override-flake original-ref resolved-ref
Override the flake registries, redirecting original-ref to resolved-ref.
