prolog_edit:edit_command(+Editor, -Command)

Determines how Editor is to be invoked using shell/1. Editor is the determined editor (see prolog_edit:edit_source/1), without the full path specification, and without a possible (.exe) extension. Command is an atom describing the command. The following %-sequences are replaced in Command before the result is handed to shell/1:

%e	Replaced by the (OS) command name of the editor
%f	Replaced by the (OS) full path name of the file
%d	Replaced by the line number

If the editor can deal with starting at a specified line, two clauses should be provided. The first pattern invokes the editor with a line number, while the second is used if the line number is unknown.

The default contains definitions for vi, emacs, emacsclient, vim, notepad^* and wordpad^*. Starred editors do not provide starting at a given line number.
