The following command is equivalent to running `nix-init --help`: ```bash nix run github:nix-community/nix-init -- --help ``` or if you don't have flakes enabled: ```bash nix run --extra-experimental-features "flakes nix-command" github:nix-community/nix-init -- --help ``` ## Usage ``` Usage: nix-init [OPTIONS] [OUTPUT] Arguments: [OUTPUT] The path or directory to output the generated file to Options: -u, --url Specify the URL -n, --nixpkgs Path to nixpkgs (in nix) -c, --config Specify the config file -h, --help Print help -V, --version Print version ``` ### Supported builders - `stdenv.mkDerivation` - `buildRustPackage` - `buildPythonApplication` and `buildPythonPackage` - `buildGoModule` ### Supported fetchers - `fetchCrate` - `fetchFromGitHub` - `fetchFromGitLab` - `fetchFromGitea` - `fetchPypi` - All other fetchers supported by [nurl] are also supported, you just have to manually input the tag/revision of the package ## Configuration nix-init will try to find `nix-init/config.toml` under XDG configuration directories ```toml # ~/.config/nix-init/config.toml # maintainers that will get added to the package meta maintainers = ["figsoda"] # path to nixpkgs, equivalent to `--nixpkgs` nixpkgs = "" # access tokens to access private repositories and avoid rate limits [access-tokens] "github.com" = "ghp_blahblahblah..." "gitlab.com".command = ["secret-tool", "or", "whatever", "you", "use"] "gitlab.gnome.org".file = "/path/to/api/token" ``` ## Changelog See [CHANGELOG.md](CHANGELOG.md) [nurl]: https://github.com/nix-community/nurl
