Problem with Homebrew Casks on MacOS

[jftuga]

I have created a new command line app here with GoReleaser:

• https://github.com/jftuga/wrapline/blob/87328eca463851b53414bff9e915eeff10e62541/.goreleaser.yml#L79
• I would like to keep wrap_in_directory set to true because I like the way this works for tarballs and zip files.

The resulting cask files lives in my personal homebrew tap here:

• https://github.com/jftuga/homebrew-tap/blob/d84447d1668b2ecb31bc5d9ef0eb4235ca71dcbe/Casks/wrapline.rb

On MacOS, I ran:

$ brew update

$ brew install --cask jftuga/tap/wrapline
==> Downloading https://github.com/jftuga/wrapline/releases/download/v1.1.2/wrapline_1.1.2_darwin_arm64.tar.xz

Error: It seems the symlink source '/opt/homebrew/Caskroom/wrapline/1.1.2/wrapline' is not there.
ERROR: Previous command failed with exit code 1

The program is not installing. What do I need to change in my .goreleaser.yml file to fix this?

Also, what was the reason for deprecating brews sections in the newer versions of GoReleaser? Was it just because of Linux? Just curious.

$ goreleaser --version | rg 'GitVersion|BuildDate'
GitVersion:    2.12.6
BuildDate:     2025-10-21T23:42:46Z

$ goreleaser check

  • thanks for using GoReleaser!

Thanks,

I am trying to add the full path to the binary here:

• https://github.com/jftuga/wrapline/blob/a9dcb04229f37a9ad6037b2c0cdf6952e6d944af/.goreleaser.yml#L95-L100
• There are two locations: binaries and at the end of system_command

When I run goreleaser release --snapshot, I see the error of map has no entry for key "Os"

  • homebrew cask
  ⨯ release failed after 1s                          error=template: failed to apply "{{ .ProjectName }}_{{ .Version }}_{{ .Os }}_{{ .Arch }}/wrapline": template: failed to apply "{{ .ProjectName }}_{{ .Version }}_{{ .Os }}_{{ .Arch }}/wrapline": map has no entry for key "Os"

I wonder if maybe goreleaser/internal/tmpl/tmpl.go needs to be updated to include Os? Just a guess.

I have found the problem tmpl.go and have submitted a PR

Would this still be correct or is your PR an alternative to homebrew_casks?

homebrew_casks:
  - name: mtoolcask
    description: "CLI tool that wraps each line of input with a specified delimiter"
    repository:
      owner: jftuga
      name: homebrew-tap
      token: "{{ .Env.HOMEBREW_TOKEN }}"
    commit_author:
      name: jftuga
      email: jftuga@users.noreply.github.com
    homepage: https://github.com/jftuga/gorel-hb-cask-test
    test: system "#{bin}/mtool version"
    install: bin.install "mtool"

I actually have an existing formula name mtool so I named this one mtoolcask to avoid collisions.

I see this error when I run goreleaser release from a binary I built from your cask-wrapped-in branch:

  ⨯ release failed after 0s
    error=
    │ yaml: unmarshal errors:
    │   line 82: field test not found in type config.HomebrewCask
    │   line 83: field install not found in type config.HomebrewCask

you should probably follow the migration guide and homebrew cask docs, your config there is incorrect.
