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;
}
