built-in method

# `print_message_tokens/3`

## Description

    print_message_tokens(Stream, Prefix, Tokens)

Built-in method for printing a list of message tokens, declared in the logtalk built-in object as a public predicate. This method is automatically called by the print_message/3 method (assuming that the message was not intercepted by a message_hook/4 definition) and calls the user-defined hook predicate print_message_token/4 for each token. When a call to this hook predicate succeeds, the `print_message_tokens/3` predicate assumes that the token have been printed. When the call fails, the `print_message_tokens/3` predicate uses a default printing procedure for the token.

## Modes and number of proofs

    print_message_tokens(@stream_or_alias, +atom, @list(nonvar)) - zero_or_one

## Errors

(none)

## Examples

    ...,
    logtalk::print_message_tokens(user_error, '% ', ['Redefining ~w ~q'-[object,foo], nl]),
