sweep: SWI-Prolog Embedded in Emacs
Abstract
Sweep is an embedding of
SWI-Prolog in GNU Emacs. It provides an interface for executing Prolog
queries and consuming their results from Emacs Lisp. Sweep further
builds on top of this interface and on top of the standard Emacs
facilities to provide advanced features for developing SWI-Prolog
programs in Emacs.
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/")))
After installing the
sweeprolog
Elisp library, load it into Emacs:
(require 'sweeprolog)
All set! You can now use Sweep for Prolog development and for
integrating Prolog into your Emacs Lisp code. For a full description of
the different features of Sweep, see
the Sweep manual.
