Modes and number of proofs¶
message_hook(@nonvar, @nonvar, @nonvar, @list(nonvar)) - zero_or_one
:- multifile(logtalk::message_hook/4). :- dynamic(logtalk::message_hook/4). % print silent messages instead of discarding them as default logtalk::message_hook(_, silent, core, Tokens) :- logtalk::message_prefix_stream(silent, core, Prefix, Stream), logtalk::print_message_tokens(Stream, Prefix, Tokens).
