library(prolog_stack)
is loaded and an
exception of the shape error(Format, Context)
is raised
Context is extended with a backtrace. To catch an error and
print its message including a backtrace, use the following template:
:- use_module(library(prolog_stack)). ..., catch_with_backtrace(Goal, Error, print_message(error, Error)), ...,
This is good practice for a catch-all wrapper around an
application. See also main/0
from library library(main)
