Homebrew Taps

After releasing to GitHub, GitLab, or Gitea, GoReleaser can generate and publish a homebrew-tap recipe into a repository that you have access to.

The brews section specifies how the formula should be created. You can check the Homebrew documentation, and the formula cookbook for more details.

# .goreleaser.yaml
brews:
  -
    # Name of the recipe
    #
    # Default: ProjectName
    # Templates: allowed
    name: myproject

    # IDs of the archives to use.
    # Empty means all IDs.
    ids:
    - foo
    - bar

    # GOARM to specify which 32-bit arm version to use if there are multiple
    # versions from the build section. Brew formulas support only one 32-bit
    # version.
    #
    # Default: 6
    goarm: 6

    # GOAMD64 to specify which amd64 version to use if there are multiple
    # versions from the build section.
    #
    # Default: v1
    goamd64: v1

    # NOTE: make sure the url_template, the token and given repo (github or
    # gitlab) owner and name are from the same kind.
    # We will probably unify this in the next major version like it is
    # done with scoop.

        # The value to be passed to `GIT_SSH_COMMAND`.
        # This is mainly used to specify the SSH private key used to pull/push

By defining the brew section, GoReleaser will take care of publishing the Homebrew tap. Assuming that the current tag is v1.2.3, the above configuration will generate a program.rb formula in the Formula folder of user/homebrew-tap repository:

class Program < Formula
  desc "How to use this binary"
  homepage "https://github.com/user/repo"
  version "v1.2.3"

  on_macos do
    url "https://github.com/user/repo/releases/download/v1.2.3/program_v1.2.3_macOs_64bit.zip"
    sha256 "9ee30fc358fae8d248a2d7538957089885da321dca3f09e3296fe2058e7fff74"
  end

  on_linux
    if Hardware::CPU.intel?
      url "https://github.com/user/repo/releases/download/v1.2.3/program_v1.2.3_Linux_64bit.zip"
      sha256 "b41bebd25fd7bb1a67dc2cd5ee12c9f67073094567fdf7b3871f05fd74a45fdd"

end

!!! info Note that GoReleaser does not generate a valid homebrew-core formula. The generated formulas are meant to be published as homebrew taps, and in their current form will not be accepted in any of the official homebrew repositories.

Head Formulas

GoReleaser does not generate head formulas for you, as it may be very different from one software to another.

Our suggestion is to create a my-app-head.rb file on your tap following homebrew's documentation.

GitHub Actions

To publish a formula from one repository to another using GitHub Actions, you cannot use the default action token. You must use a separate token with content write privileges for the tap repository. You can check the resource not accessible by integration for more information.

Limitations

• Only one GOARM build is allowed;
