DrRacket is an IDE for the programming language Racket, a dialect of the languages Lisp/Scheme. Racket is a good starting point if you want to learn the functional programming paradigm. This blog entry explains how to install the DrRacket IDE on your Mac.
To install DrRacket on macOS, you can simply use your existing Homebrew installation to install the program from the repository.
brew cask install racket
This command will install the programming language Racket with some libraries and the IDE DrRacket.
Note that if you use the
PtlRacket formula for Homebrew, you will install a very minimal installation of racket without the IDE DrRacket and with only a few libraries.
brew install ptl-racket
