@{
|
|
|
|
The interaction between YAP and the user relies on YAP's ability to
|
|
portray messages. These messages range from prompts to error
|
|
information. All message processing is performed through the builtin
|
|
print_message/2, in two steps:
|
|
|
|
+ The message is processed into a list of commands
|
|
+ The commands in the list are sent to the `format/3` builtin
|
|
in sequence.
|
|
|
|
|
|
The first argument to print_message/2 specifies the importance of
|
|
the message. The options are:
|
|
|
|
+ `error`
|
|
error handling
|
|
+ `warning`
|
|
compilation and run-time warnings,
|
|
+ `informational`
|
|
generic informational messages
|
|
+ `help`
|
|
help messages (not currently implemented in YAP)
|
|
+ `query`
|
|
query used in query processing (not currently implemented in YAP)
|
|
+ `silent`
|
|
messages that do not produce output but that can be intercepted by hooks.
|
|
|
|
|
|
The next table shows the main predicates and hooks associated to message
|
|
handling in YAP:

/** @pred print_message_lines(+ _Stream_, + _Prefix_, + _Lines_)
|
|
|
|
|
|
Print a message (see print_message/2) that has been translated to
|
|
a list of message elements. The elements of this list are:
|
|
|
|
+ _Format_-_Args_
|
|
Where _Format_ is an atom and _Args_ is a list
|
|
of format argument. Handed to `format/3`.
|
|
+ `flush`
|
|
If this appears as the last element, _Stream_ is flushed
|
|
(see `flush_output/1`) and no final newline is generated.
|
|
+ `at_same_line`
|
|
If this appears as first element, no prefix is printed for
|
|
the first line and the line-position is not forced to 0
|
|
(see `format/1`, `~N`).
|
|
+ `<Format>`
|
|
Handed to `format/3` as `format(Stream, Format, [])`.
|
|
+ nl
|
|
A new line is started and if the message is not complete
|
|
the _Prefix_ is printed too.
