## Using the flake ## Using the flake
For the experimental flakes functionality we provide poetry2nix as a flake providing an overlay For the experimental flakes functionality we provide _poetry2nix_ as a flake providing an overlay
to use with [nixpkgs](https://nixos.org/nixpkgs/manual). to use with [nixpkgs](https://nixos.org/nixpkgs/manual). Additionally, the flake provides
a flake template to quickly start using _poetry2nix_ in a project:
#### Example ```sh
nix flake --template github:nix-community/poetry2nix
```nix
{
description = "Your flake using poetry2nix";
inputs.nixpkgs.url = "github:NixOS/nixpkgs";
inputs.utils.url = "github:numtide/flake-utils";
inputs.poetry2nix-src.url = "github:nix-community/poetry2nix";
outputs = {nixpkgs, utils, poetry2nix-src, self}: utils.lib.eachDefaultSystem (system: let
pkgs = import nixpkgs { inherit system; overlays = [ poetry2nix-src.overlay ]; };
in
{
# use pkgs.poetry2nix here.
});
}
``` ```
