使用 Homebrew 发布软件

本文主要是介绍使用 Homebrew 发布软件，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1 相关概念

• Keg（酒桶）：安装好的脚本、软件等；
• Cellar（酒窖）：所有用 Homebrew 安装在本地的脚本、软件组成的集合；
• Formula（配方）：定义如何下载、编译和安装脚本或软件的 Ruby 脚本；
• Tap：一个包含若干 Formula 的 GitHub 专案。

2 创建 Formula

假如有一个软件的二进制包，需要先上传到网络上，并获取下载链接，如： https://github.com/Bytom/bytom/releases/download/v1.0.7/bytom-1.0.7-darwin_amd64.tgz。

然后执行如下命令：

$ brew create https://github.com/Bytom/bytom/releases/download/v1.0.7/bytom-1.0.7-darwin_amd64.tgz

之后 brew 就在其目录 /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/中自动创建一个 ruby 文件 bytom.rb：

# Documentation: https://docs.brew.sh/Formula-Cookbook
#                https://www.rubydoc.info/github/Homebrew/brew/master/Formula
# PLEASE REMOVE ALL GENERATED COMMENTS BEFORE SUBMITTING YOUR PULL REQUEST!
class Bytom < Formuladesc "Official Go implementation of the Bytom protocol "homepage "https://bytom.io/"url "https://github.com/Bytom/bytom/releases/download/v1.0.7/bytom-1.0.7-darwin_amd64.tgz"sha256 "25dd62343157fe6eb7a983edb1455f457cfca07552f02e1f9142227bd961a4a5"# depends_on "cmake" => :builddef install# ENV.deparallelize  # if your formula fails when building in parallel# Remove unrecognized options if warned by configuresystem "./configure", "--disable-debug","--disable-dependency-tracking","--disable-silent-rules","--prefix=#{prefix}"# system "cmake", ".", *std_cmake_argssystem "make", "install" # if this fails, try separate make/make install stepsendtest do# `test do` will create, run in and delete a temporary directory.## This test will fail and we won't accept that! For Homebrew/homebrew-core# this will need to be a test that verifies the functionality of the# software. Run the test with `brew test bytom`. Options passed# to `brew install` such as `--HEAD` also need to be provided to `brew test`.## The installed folder is not in the path, so use the entire path to any# executables being tested: `system "#{bin}/program", "do", "something"`.system "false"end
end

之后按照软件的实际需求对该文件进行编辑，可以修改或者增加以下内容：

desc           # 说明，默认已填写
homepage       # 主页，默认已填写
url            # 文件下载地址，默认已填写
version        # 软件版本号，该字段可以自己添加，强烈建议添加
sha256         # 信息摘要，默认已填写

文件的 sha256 摘要可以使用 openssl 命令获取：

$ openssl sha256 bytom-1.0.7-darwin_amd64.tgz
SHA256(bytom-1.0.7-darwin_amd64.tgz)= 25dd62343157fe6eb7a983edb1455f457cfca07552f02e1f9142227bd961a4a5

之后是文件依赖部分：

# depends_on "cmake" => :build

该部分按照实际需求填写。之后是安装部分：

  def install# ENV.deparallelize  # if your formula fails when building in parallel# Remove unrecognized options if warned by configuresystem "./configure", "--disable-debug","--disable-dependency-tracking","--disable-silent-rules","--prefix=#{prefix}"# system "cmake", ".", *std_cmake_argssystem "make", "install" # if this fails, try separate make/make install stepsend

system 后面是需要执行的安装命令，这个根据实际软件编译过程进行修改。

因为 bytom 是已经编译好的二进制软件包，所以实际的文件进行修改如下：

class Bytom < Formuladesc "Official Go implementation of the Bytom protocol "homepage "https://bytom.io/"url "https://github.com/Bytom/bytom/releases/download/v1.0.7/bytom-1.0.7-darwin_amd64.tgz"version "1.0.7"sha256 "25dd62343157fe6eb7a983edb1455f457cfca07552f02e1f9142227bd961a4a5"def installsystem 'mv bytomd-darwin_amd64 bytomd'system 'mv bytomcli-darwin_amd64 bytomcli'bin.install "bytomd"bin.install "bytomcli"endtest do# `test do` will create, run in and delete a temporary directory.## This test will fail and we won't accept that! For Homebrew/homebrew-core# this will need to be a test that verifies the functionality of the# software. Run the test with `brew test bytom`. Options passed# to `brew install` such as `--HEAD` also need to be provided to `brew test`.## The installed folder is not in the path, so use the entire path to any# executables being tested: `system "#{bin}/program", "do", "something"`.system "false"endend

安装过程的 bin.install 是调用 Homebrew 安装二进制软件。保存后，执行安装过程：

$ brew install bytom

之后软件就自动安装在 /usr/local/bin 文件夹下。

3 创建 Tap

之后，为了使其他用户也能安装上面的配置文件进行安装软件，则需要将上一步制作的 bytom.rb 文件上传到 GitHub 上，以供其他用户下载。

创建的 GitHub 仓库名的前缀统一为 homebrew-。例如将 bytom.rb 文件放置在 Bytom 组织的 homebrew-bytom 仓库下。

4 安装创建的软件

初次安装需要指定 tap：

$ brew tap bytom/bytom

该命令将用户名为 bytom 的 homebrew-bytom 联系起来，之后安装 bytom 软件时候就不需要再次指定了。然后进行安装：

$ brew install bytom

验证 bytomd 和 bytomcli 是否正确安装：

$ bytomd version
1.0.7+96a0b65f
$ bytomcli version
Bytomcli v1.0.7+96a0b65f darwin/amd64
