Autorun predicate

Is there a way to define autorun predicate, which will run after loading a file?

Yeah, I know about swipl -s fil开发者_Go百科e.pl -g "main.", but still looking for something, which can be put in source file file.pl

:- initialization(main).

Make sure the main directive always calls halt/0, else you will get a toplevel when it fails. Or put in an unconditional call to halt/0:

:- initialization(once(((main ; true), halt))).
