Homebrew

The missing package manager for macOS

Install Homebrew
```
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
```
Paste that at a Terminal prompt.

The script explains what it will do and then pauses before it does it. There are more installation options here (required for OS X Lion 10.7 and below).
What Does Homebrew Do?

Homebrew installs the stuff you need that Apple didn’t.
```
$ brew install wget
```

Homebrew installs packages to their own directory and then symlinks their files into /usr/local.

$ cd /usr/local
$ find Cellar
Cellar/wget/1.16.1
Cellar/wget/1.16.1/bin/wget
Cellar/wget/1.16.1/share/man/man1/wget.1

$ ls -l bin
bin/wget -> ../Cellar/wget/1.16.1/bin/wget

Homebrew won’t install files outside its prefix, and you can place a Homebrew installation wherever you like.

Trivially create your own Homebrew packages.

$ brew create https://foo.com/bar-1.0.tgz
Created /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/bar.rb

It's all Git and Ruby underneath, so hack away with the knowledge that you can easily revert your modifications and merge upstream updates.
```
$ brew edit wget # opens in $EDITOR!
```

Homebrew formulae are simple Ruby scripts:

class Wget < Formula
  homepage "https://www.gnu.org/software/wget/"
  url "https://ftp.gnu.org/gnu/wget/wget-1.15.tar.gz"
  sha256 "52126be8cf1bddd7536886e74c053ad7d0ed2aa89b4b630f76785bac21695fcd"

  def install
    system "./configure", "--prefix=#{prefix}"
    system "make", "install"
  end
end

Homebrew complements macOS. Install your gems with gem, and their dependencies with brew.
"To install, drag this icon..." no more. brew cask installs macOS apps, fonts and plugins and other non-open source software.
```
$ brew cask install firefox
```

Making a cask is as simple as creating a formula.

$ brew cask create foo
Editing /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask/Casks/foo.rb
