central predicate for editing something is edit/1,
an extensible front-end that searches for objects (files, predicates,
modules, as well as XPCE classes and methods) in the Prolog database. If
multiple matches are found it provides a choice. Together with the
built-in completion on atoms bound to the
TAB key this
provides a quick way to edit objects:
?- edit(country). Please select item to edit: 1 chat:country/10 '/staff/jan/lib/prolog/chat/countr.pl':16 2 chat:country/1 '/staff/jan/lib/prolog/chat/world0.pl':72 Your choice?
