NOTICE: The Cask syntax is changing! (8 Sep 2014)

There will be a period of transition while we update the Cask DSL to use new forms described in #4688.

End users should not notice a difference — but see below about upgrading on errors. Cask authors will need to adjust to the new DSL forms.

The Cask DSL 1.0 will be documented in CASK_LANGUAGE_REFERENCE.md and cask_language_deltas.md.

Code to support most of the new DSL forms has been in release for several weeks; most users are already running forward compatible code1.

The transition officially begins with version 0.40.0, released 8 Sep 2014. Cask definition files will also be changing. If you experience an error when running Homebrew-cask, please run

$ brew update && brew upgrade brew-cask && brew cleanup && brew cask cleanup

to get the latest code.

1 forward compatibility began with v0.38.0, released 28 Jul 2014

"To install, drag this icon..." no more!

Build Status Code Climate Bitdeli Badge

Let's see if we can get the elegance, simplicity, and speed of Homebrew for the installation and management of GUI Mac applications such as Google Chrome and Adium.

Homebrew-cask provides a friendly homebrew-style CLI workflow for the administration of Mac applications distributed as binaries.

It's implemented as a homebrew "external command" called cask.

Let's try it!

$ brew install caskroom/cask/brew-cask
$ brew cask install google-chrome
=> Downloading https://dl.google.com/chrome/mac/stable/GGRO/googlechrome.dmg
=> Success! google-chrome installed to /opt/homebrew-cask/Caskroom/google-chrome/stable-channel
=> Linking Google Chrome.app to /Users/phinze/Applications/Google Chrome.app

And there we have it. Google Chrome installed with a few quick commands: no clicking, no dragging, no dropping.

$ open ~/Applications/"Google Chrome.app"
