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/
