Using XPCE

The XPCE GUI tool for Prolog comes with a build-in emacs clone written in Prolog. It's emacs mode does proper indentation, full syntax checking by calling the SWI-Prolog parser, warning for singleton variables and finding predicate definitions based on the source-information from the Prolog database.

Both syntax checking and singleton warnings are generated each time you type the finishing full-stop of a clause or using the C-c C-s command.

See BindEditor for selecting PceEmacs as default editor.

Cross Referencing

As of SWI-Prolog 3.4.0/XPCE 5.0.9, the prolog mode of PceEmacs performs automatic cross referencing, colouring code according to whether it is defined and/or accessed.
