首先

在中国，Homebrew和Homebrew Cask的软件包也可以使用Brewfile进行管理，但是在Brewfile中添加软件包并在第二次或以后的执行时会出现很多”already installed”之类的警告，不太令人愉快。此外，Atom编辑器的软件包可以使用apm命令进行管理，但是把它们和其他软件包一起使用Ansible进行管理可以使整个过程更加简洁明了，所以我尝试了一下。

我创建了三个用于Ansible角色的模块和一个用于apm的模块，并按照@znz blog的参考将其注册到了Ansible Galaxy，因此你可以轻松地使用。

使用步骤

安装Homebrew、Python和Ansible。

xcode-select --install

请在这里启动Xcode并同意许可证。

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
brew install python
brew install ansible

下载用于Homebrew、Cask和Atom软件包管理的Ansible角色。

在这里，将~/ansible-work作为工作目录。

mkdir ~/ansible-works
cd ~/ansible-works
ansible-galaxy install --roles-path=. hnakamur.homebrew-packages
ansible-galaxy install --roles-path=. hnakamur.homebrew-cask-packages
ansible-galaxy install --roles-path=. hnakamur.atom-packages 

创建库存文件

如果使用Homebrew进行安装，则/usr/local/etc/ansible/hosts将成为清单文件。

我们按照以下的方式创建文件。

mkdir -p /usr/local/etc/ansible
echo localhost > /usr/local/etc/ansible/hosts

创建 localhost.yaml 文件

请根据您想使用的软件包进行适当调整，以以下方式创建localhost.yaml文件。

- hosts: localhost
  connection: local
  gather_facts: no           
  sudo: no
  vars:
    homebrew_packages_taps:
      - homebrew/binary
      - homebrew/dupes
    homebrew_packages_packages:
      - { name: readline }
      - { name: openssl, state: linked }
      - { name: ansible }
      - { name: cmake }
      - { name: ctags }
      - { name: direnv }
      - { name: docker }
      - { name: git }
      - { name: jq }
      - { name: hub }
      - { name: imagemagick }
      - { name: mercurial }
      - { name: mysql }
      - { name: packer }
      - { name: pkg-config }
      - { name: pwgen }
      - { name: python }
      - { name: reattach-to-user-namespace }
      - { name: redis }
      - { name: subversion }
      - { name: the_silver_searcher }
      - { name: tig }
      - { name: tmux }
      - { name: whois }
      - { name: xz }
      - { name: vim }
      - { name: wget }
      - { name: zsh, install_options: disable-etcdir }
    homebrew_cask_packages_packages:
      - atom
      - calibre
      - firefox
      - google-chrome
      - google-japanese-ime
      - grandperspective
      - hipchat
      - iterm2
      - java
      - keepassx
      - kindle
      - mysqlworkbench
      - skype
      - spark
      - vagrant
      - virtualbox
      - zeroxed
    atom_packages_packages:
      - project-manager
      - recent-files
  roles:
    - hnakamur.homebrew-packages
    - hnakamur.homebrew-cask-packages
    - hnakamur.atom-packages

执行Ansible

ansible-playbook localhost.yml

从第二次开始的执行结果

% ansible-playbook localhost.yml

如果在homebrew模块中指定了state=link，那么它总是会变为changed=1，这有点不理想，但除此之外，不会变为changed而是按顺序展示ok的感觉是可以的。
