3.3.1 Locating things to edit

The 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  '/home/jan/.config/swi-prolog/lib/chat/countr.pl':16
  2 chat:country/1   '/home/jan/.config/swi-prolog/lib/chat/world0.pl':72

Your choice?
