Installing Sweep requires:

• Emacs 27 or later, and
• SWI-Prolog 8.5.18 or later.

Sweep is available from NonGNU ELPA, to install it simply type in Emacs M-x package-install RET sweeprolog RET.

Note that in Emacs prior to version 28, you need to explicitly enable NonGNU ELPA by adding something like the following to your Emacs configuration:

  (with-eval-after-load 'package
    (add-to-list 'package-archives '("nongnu" . "https://elpa.nongnu.org/nongnu/")))
