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

    # Alternative names for the current recipe.
    #
    # Useful if you want to publish a versioned formula as well, so users can
    # more easily downgrade.
    #
    # Since: v1.20 (pro)
    # Templates: allowed
    alternative_names:
      - myproject@{{ .Version }}
      - myproject@{{ .Major }}

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

    # Sets the app file within a DMG.
    #
    # Since: 1.24 (pro)
    app: MyApp.app

    # 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.

    # URL which is determined by the given Token (github, gitlab or gitea).
    #
    # Default depends on the client.
    # Templates: allowed
    url_template: "https://github.mycompany.com/foo/bar/releases/download/{{ .Tag }}/{{ .ArtifactName }}"

    # Allows you to set a custom download strategy. Note that you'll need
    # to implement the strategy and add it to your tap repository.
    # Example: https://docs.brew.sh/Formula-Cookbook#specifying-the-download-strategy-explicitly
    download_strategy: CurlDownloadStrategy

    # Allows you to add a custom require_relative at the top of the formula
    # template.

    # Setting this will prevent goreleaser to actually try to commit the updated
    # formula - instead, the formula file will be stored on the dist folder only,
    # leaving the responsibility of publishing it to the user.
    # If set to auto, the release will not be uploaded to the homebrew tap

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
    if Hardware::CPU.arm? && !Hardware::CPU.is_64_bit?
      url "https://github.com/user/repo/releases/download/v1.2.3/program_v1.2.3_Linux_armv7.zip"
      sha256 "78f31239430eaaec01df783e2a3443753a8126c325292ed8ddb1658ddd2b401d"
    end
    if Hardware::CPU.arm? && Hardware::CPU.is_64_bit?
      url "https://github.com/user/repo/releases/download/v1.2.3/program_v1.2.3_Linux_arm64.zip"

    end
  end

  depends_on "git"
  depends_on "zsh" => :optional

  def install
    bin.install "program"
  end

  def post_install
  	etc.install "app-config.conf"
  end
end

!!! info

Note that GoReleaser does not generate a valid homebrew-core formula.
The generated formulas are meant to be published as
[homebrew taps](https://docs.brew.sh/Taps.html), 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.

Versioned formulas

!!! success "GoReleaser Pro"

This requires [GoReleaser Pro](/pro/).

GoReleaser can also create a versioned formula. For instance, you might want to make keep previous minor versions available to your users, so they easily downgrade and/or keep using an older version.

To do that, use alternative_names:

# .goreleaser.yaml
brews:
  - name: foo
    alternative_names:
      - "foo@{{ .Major }}.{{ .Minor }}"
    # other fields

So, if you tag v1.2.3, GoReleaser will create and push foo.rb and foo@1.2.rb.

Later on, you can tag v1.3.0, and then GoReleaser will create and push both foo.rb (thus overriding the previous version) and foo@1.3.rb. Your users can then brew install foo@1.2 to keep using the previous version.

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;
