All predicatesShow -- Editor interface

This module implements the generic editor interface. It consists of two extensible parts with little in between. The first part deals with translating the input into source-location, and the second with starting an editor.

Source edit(+Spec)
Edit indicated object.
Source edit
Edit associated or script file. This is the Prolog file opened by double-clicking or the file loaded using
% swipl [-s]
Source locate(+Spec, -FullSpec, -Location)[multifile]
Source locate(+Spec, -Location)[multifile]
Locate object from the specified location.
Source do_edit_source(+Location)[private]
Actually call the editor to edit Location, a list of Name(Value) that contains file(File) and may contain line(Line). First the multifile hook edit_source/1 is called. If this fails the system checks for XPCE and the prolog-flag editor. If the latter is built_in or pce_emacs, it will start PceEmacs.

Finally, it will get the editor to use from the prolog-flag editor and use edit_command/2 to determine how this editor should be called.

Source editor(-Editor)[private]
Determine the external editor to run.
Source edit_command(+Editor, -Command)[multifile]
This predicate should specify the shell-command called to invoke the user's editor. The following substitutions will be made:
%ePath name of the editor
%fPath name of the file to be edited
%dLine number of the target
Source select_location(+Pairs, +UserSpec, -Location)[multifile]
