This is a sample user-initialisation file for SWI-Prolog. If you wish to
customise prolog, make a copy of this file and edit it to your
preferences.
Installation:
Unix/MacOS: ~/.plrc
Windows: <appdata>/pl.ini (see win_folder(appdata, AppData))
More hints on useful things you can put into this file are in the
SWI-Prolog reference manual. Notably look at debugger settings, editor
hooks, file_search_path/2, set_prolog_flag/2 and portray/1.

* IDE *
*******************************/
% Use this if you want to run the development tools in a separate
% thread. Doing allows you to use the editor, thread monitor and
% other tools while you are running a (long) query from the
% toplevel.
%
% Works fairly well on Unix systems, but you cannot run or develop
% XPCE applications this way. Occasionally deadlocks (in partcular
% when using XPCE applications that are not aware of the
% possibility that XPCE runs in another thread). Please report
% reproducable deadlocks. You typically have a deadlock if the
% interface or toplevel becomes unresponsive while no CPU time is
% being used.

/*******************************
* EDITOR *
*******************************/
% Define the editor to use. Note that more advanced manipulation
% of this is defined in the SWI-Prolog reference manual, section
% "Listing and Editor Interface"
%
% The value pce_emacs (or built_in) causes the system to use the
% built-in editor PceEmacs if the environment provides for a GUI.
% pce_emacs is the default if XPCE is available.
%
% The second entry defines an arbitrary editor and how to tell
% SWI-Prolog to open a file with it on a specified line-number.
% :- set_prolog_flag(editor, pce_emacs).
% :- set_prolog_flag(editor, pico).
%:- multifile
% prolog_edit:edit_command/2.
%

%prolog_edit:edit_command(pico, '%e "%f"').
/*******************************
* DEBUGGING *
*******************************/
% If you prefer graphical tracing, add the line below.
% :- (current_prolog_flag(gui, true) -> guitracer ; true).
% Determine how terms are printed by the debugger and toplevel. The
% values here are defaults. max_depth(10) replaces all subterms at
% a greater depth with elipses (...). See write_term/3 for further
% explanation and more options.
% :- set_prolog_flag(toplevel_print_options,
% [quoted(true), portray(true), max_depth(10)]).
% :- set_prolog_flag(debugger_print_options,
% [quoted(true), portray(true), max_depth(10)]).
% If you want to suppress printing toplevel query variables
% starting with an `_'
% :- set_prolog_flag(toplevel_print_anon, false).
% If you do not want the tracer to stop at at the exit port.
% :- leash(-exit).
/*******************************
* MISC SETTINGS *
*******************************/
% Use the flag below to disable coloured output in all cases.
% Normally, coloured output is enabled if the output is a
% terminal.
% :- set_prolog_flag(color_term, false).
% Specify colors for the above, based on the message kind See
% ansi_format/3 for specifying visual effects. The table below
% duplicates the default behavior. Notably on terminals with a
% dark background, yellow might be a better choice for warnings
% and errors.
%:- multifile user:message_property/2.
%
%user:message_property(informational, color(fg(green))).
%user:message_property(information, color(fg(green))).
%user:message_property(debug, color(fg(blue))).
%user:message_property(warning, color(fg(red))).
%user:message_property(error, color([fg(red),bold])).
% If you want to access the command-history like a Unix shell,
% set =history= to the number of commands to remember.
% :- set_prolog_flag(history, 50).
% Set =save_history= to =false= if you never want to save/restore the
% command history. Normally, the history is enabled if the system
% provides a history and the input comes from a terminal.
% :- set_prolog_flag(save_history, false).
