flakelight-go

Go module for flakelight.

Initializes a Go project flake from its source directory.

Configured options

Sets package to a Go package built from the flake source.

Adds go to the default devShell.

Adds checks for go test and gofmt.

Configures go files to be formatted with gofmt.

Options

fileset configures the fileset the package is built with. By default, it includes *.go, go.mod, go.sum, and .golangci.yml.

go.version selects the Go version by looking up pkgs.go_1_<version>. For example, go.version = 23; uses pkgs.go_1_23. The default is 25.

Getting started

To create a new project in an empty directory, run the following:

nix flake init -t github:chikof/flakelight-go

Existing projects can use one of the example flake.nix files below.

Example flake

You can call this flake directly:

{
  inputs.flakelight-go.url = "github:chikof/flakelight-go";
  outputs = { flakelight-go, ... }: flakelight-go ./. { };
}

With full control over package output (inclusing custom binaries):

{
  inputs.flakelight-go.url = "github:chikof/flakelight-go";

  outputs = {flakelight-go, ...}:
    flakelight-go ./. {
      package = pkgs:
        pkgs.buildGoModule {
          pname = "my-app";
          version = "0.1.0";
          src = ./.;

          # Build multiple binaries from cmd/
          subPackages = [ "./cmd/api" "./cmd/worker" ];

          vendorHash = "sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=";
        };
    };
}

Alternatively, add this module to your Flakelight config:

{
  inputs = {
    flakelight.url = "github:nix-community/flakelight";
    flakelight-go.url = "github:chikof/flakelight-go";
  };

  outputs = { flakelight, flakelight-go, ... }: flakelight ./. {
    imports = [ flakelight-go.flakelightModules.default ];

    go.version = 25;
  };
}
