Homebrew

After releasing to GitHub or GitLab, 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.

!!! warning If you have multiple 32-bit arm versions in each build section, and you do not specify any ids in the brew section, it will default to all artifacts and GoReleaser will fail.

# .goreleaser.yml
brews:
  -
    # Name template of the recipe
    # Default to project name
    name: myproject

    # IDs of the archives to use.
    # Defaults to all.
    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 atm only one 32-bit version.
    # Default is 6 for all artifacts or each id if there a multiple versions.
    goarm: 6

    # 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.

    # GitHub/GitLab repository to push the formula to
    # Gitea is not supported yet, but the support coming
    tap:
      owner: repo-owner
      name: homebrew-tap
      # Optionally a token can be provided, if it differs from the token provided to GoReleaser
      token: "{{ .Env.HOMEBREW_TAP_GITHUB_TOKEN }}"

    # Template for the url which is determined by the given Token (github or gitlab)
    # Default for github is "https://github.com/<repo_owner>/<repo_name>/releases/download/{{ .Tag }}/{{ .ArtifactName }}"
    # Default for gitlab is "https://gitlab.com/<repo_owner>/<repo_name>/uploads/{{ .ArtifactUploadHash }}/{{ .ArtifactName }}"
    url_template: "http://github.mycompany.com/foo/bar/releases/{{ .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
    # Default is empty.
    download_strategy: CurlDownloadStrategy.

    # Allows you to add a custom require_relative at the top of the formula template
    # Default is empty
    custom_require: custom_download_strategy

    # Git author used to commit to the repository.
    # Defaults are shown.
    commit_author:
      name: goreleaserbot
      email: goreleaser@carlosbecker.com

    # Folder inside the repository to put the formula.
    # Default is the root folder.
    folder: Formula

    # Caveats for the user of your binary.
    # Default is empty.
    caveats: "How to use this binary"

    # Your app's homepage.
    # Default is empty.
    homepage: "https://example.com/"

    # Your app's description.
    # Default is empty.
    description: "Software to create fast and easy drum rolls."

    # 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
    # in case there is an indicator for prerelease in the tag e.g. v1.0.0-rc1
    # Default is false.
    skip_upload: true

    # Custom block for brew.
    # Can be used to specify alternate downloads for devel or head releases.
    # Default is empty.
    custom_block: |
      head "https://github.com/some/package.git"
      ...      

    # Packages your package depends on.
    dependencies:
      - name: git
      - name: zsh
        type: optional

    # Packages that conflict with your package.
    conflicts:
      - svn
      - bash

    # Specify for packages that run as a service.
    # Default is empty.
    plist: |
      <?xml version="1.0" encoding="UTF-8"?>
      ...      

    # So you can `brew test` your formula.
    # Default is empty.
    test: |
      system "#{bin}/program --version"
      ...      

    # Custom install script for brew.
    # Default is 'bin.install "program"'.
    install: |
      bin.install "program"
      ...      

!!! tip Learn more about the name template engine.

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"

  if os.Mac?
    url "https://github.com/user/repo/releases/download/v1.2.3/program_v1.2.3_macOs_64bit.zip"
    sha256 "9ee30fc358fae8d248a2d7538957089885da321dca3f09e3296fe2058e7fff74"
  elsif os.Linux?
    url "https://github.com/user/repo/releases/download/v1.2.3/program_v1.2.3_Linux_64bit.zip"
    sha256 "b41bebd25fd7bb1a67dc2cd5ee12c9f67073094567fdf7b3871f05fd74a45fdd"
    if Hardware::CPU.arm?
      if Hardware::CPU.is_64_bit?
        url "https://github.com/user/repo/releases/download/v1.2.3/program_v1.2.3_Linux_arm64.zip"
            sha256 "97cadca3c3c3f36388a4a601acf878dd356d6275a976bee516798b72bfdbeecf"
      else
        url "https://github.com/user/repo/releases/download/v1.2.3/program_v1.2.3_Linux_armv7.zip"
        sha256 "78f31239430eaaec01df783e2a3443753a8126c325292ed8ddb1658ddd2b401d"
      end
    end
  end

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

  def install
    bin.install "program"
  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, 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.
