Homebrew is free and open software that simplifies the install of programs on macOS and Linux. The name comes from the idea of making apps for Mac based on the preferences of the user. You can imagine it as a store for programs that developers and users need but that you can not easily reach.
It installs what Apple or Linux does not carry out of the box.
Types of Homebrew
Homebrew is based on Git and Ruby. It works with Ruby and fits well with GitHub, so it is easy for average folks to use. During the first install it sets up files in a default folder as a Git deposit.
You can run the installer by means of a script from GitHub and it currently works on macOS and Linux. After cloning of the deposit, the system takes around 82MB. Without Homebrew it needs less than 100MB on Mac.
The project is not-for-profit and runs entirely thanks to volunteers wihtout pay. The money helps to cover costs for programs, servers and hosting for continuous testing and future improvements. Homebrew is safe to use.
It no longer changes permissions, so it acts just like any other program in the system.
By means of the tap-command without a set URL, Homebrew downloads a formula deposit from GitHub by means of HTTPS. Because many taps are hosted on GitHub, there is a shortcut for that. With a pointed URL it can tap a formula deposit from anywhere by means of any transfer method.
Popular packages installed through Homebrew include command line tools for Amazon Web Services, bash completion for smarter auto-completion, calculators, tools four file encryption and programs like dos2unix.
The word “homebrew” also points to something entirely different in other areas. In brewing it relates to making beer, wine, cider or mead at home. A typical amount for a homebrew recipe is 19 liters or 5 American gallons, because many home brewers like to store beer in Cornelius kegs, that hold exactly 19 liters.
You can start the home brewing hobby for under a hundred dollars. Newcomers commonly start with malt extract and the results give genuinely not bad beer. From here moving to grain methods for brewing is anatural next stage.
Homebrew also appears in the video game world. It relates to new games created for old platforms. Playing new homebrew games on classic consoles is a whole hobby on its own.
And in Dungeons & Dragons, homebrew points to homemade backgrounds, magic objects, monsters and spells done outside the official rules. A simple way to create a homebrew spell is to take an existing spell that best suits, observe similar spells and make some changes.
