Brew Plugin

Automate the creation of Homebrew formulae. This plugin can be use with any other package manager plugin.

NOTE: This plugin does not work in lerna monorepos that use independent versioning.

Installation

This plugin is not included with the auto CLI installed via NPM. To install:

npm i --save-dev @auto-it/brew
# or
yarn add -D @auto-it/brew

Usage

To use this plugin you will need to add the required configuration and a template file.

  • executable - REQUIRED: The executable to create a formula for
  • name - REQUIRED: The name of the formula to create
  • formula - A path to the formula template. Default is './formula-template.rb'
{
  "plugins": [
    [
      "brew",
      {
        "executable": "path/to/some/executable",
        "name": "name-of-formula",
        "formula": "path/to/formula/template"
      }
    ]
  ]
}

Create a template name ./formula-template.rb at the root of the project (or use the formula option to customize the location)/ The template file must be a valid homebrew ruby file.

auto will replace the following tokens in the template file:

  • $VERSION - The version being published
  • $SHA - The sha of the executable being included in the formula

Here is the template auto uses to publish it's own brew formula:

class Auto < Formula
  desc "Generate releases based on semantic version labels on pull requests."
  homepage "https://intuit.github.io/auto/home.html"
  url "https://github.com/intuit/auto/releases/download/$VERSION/auto-macos.gz"
  version "$VERSION"
  sha256 "$SHA"

  def install
    libexec.install Dir["*"]
    bin.install libexec/"auto-macos"
    mv bin/"auto-macos", bin/"auto"
  end

  test do
    system bin/"auto", "--version"
  end
end

Multiple Formulae

You can also use this to create multiple brew formulae.

  "plugins": [
    [
      "brew",
      [
        {
          "executable": "path/to/some/executable",
          "name": "name-of-formula",
          "formula": "path/to/formula/template"
        },
        {
          "executable": "path/to/another/executable",
          "name": "another-formula",
          "formula": "path/to/formula/another"
        }
      ]
    ]
  ]
