built-in method
print_message/3
Description
print_message(Kind, Component, Term)
Built-in method for printing a message represented by a term, which is
converted to the message text using the
logtalk::message_tokens(Term, Component)
hook non-terminal. This method is declared in the
logtalk built-in
object as a public predicate. The line prefix and the output stream used
for each Kind-Component pair can be found using the
logtalk::message_prefix_stream(Kind, Component, Prefix, Stream)
hook predicate.
This predicate starts by converting the message term to a list of tokens
and by calling the
logtalk::message_hook(Message, Kind, Component, Tokens)
hook predicate. If this predicate succeeds, the print_message/3
predicate assumes that the message have been successfully printed.
By default: messages of kind debug or debug(_) are only printed when
the debug flag is turned on; messages of kind banner, comment, or
comment(_) are only printed when the report flag is set to on;
messages of kind warning and warning(_) are not printed when the
report flag is set to off; messages of kind silent and silent()
are not printed (but can be intercepted).
