I'd like to get the output of apropos/1 and help/1 etc. inside my Emacs buffer, instead of an XPCE window. I'm using SWI-Prolog under Linux.
What I have tried:
Setting flags in the init file (~/.plrc):
:- set_prolog_flag(gui, false).
:- set_prolog_flag(xpce, false).
Calling swipl with the --nopce flag (a wild guess looking at /usr/lib/swi-prolog/xpce.rc)
ssh localhost, effectively emulating a terminal-only machine, which worked, but there must be a better solution...
And yes, I could just uninstall the swi-prolog-x package, but I may want to write GUI programs in the future. Ideally I would like to turn off the GUI only for the documentation / debugging.
EDIT:
I've found out part of the solution: the goals online_help:give_help/1 and online_help:give_apropos seem to be what I need. I just need to re-hook these onto help and apropos, maybe via prolog:help_hook/1. Any ideas?
[~]# unset DISPLAY
swipl --nopce
This a an undocumented flag... Normally it is only used when building the system/
