Using PceEmacs

The XPCE GUI tool for Prolog comes with a build-in emacs clone written in Prolog. It's Prolog 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. Syntax colouring of clause heads and goals is based on information from the cross-referencer.

Both syntax checking and singleton warnings are generated for the clause in which the caret appears after every keystroke. Global analysis of the file is done after a shot idle time or after typing C-l (control+L).
