The possible flags, their values and their meanings are:
Flags Values Description
----------------------------------------------------------------------
auxiliary on,off predicate is a compiler auxiliary
break_lines list of list of predicate source File:Line
atom:integer that currently have breakpoints set
call_type prolog, predicate calling external convention
code_size an integer size of abstract machine
code in words (32/64 bits)
debugged on, off compiled in debugging mode
declared on, off predicate was declared
defined on, off predicate code exists
definition_module an atom where the procedure is defined
demon on, off predicate is a demon
deprecated on, off predicate is deprecated,
warning on use
leash stop,print, see below
notrace
meta_predicate pred(Prop1,...) the meta-arguments of the predicate
(from a meta_predicate/1 declaration)
mode pred(Mode1,...) the mode of the predicate (from a
mode/1 or meta_predicate/1 declaration)
parallel on, off clauses may be executed in parallel
port_calls list of list of DefModule:Name/Arity for
atom:atom/int the predicate's body goals where
breakpoints can be added. The
port_lines option returns the source
information for these ports, in the
same order
port_lines list of list of predicate source File:Line
atom:integer where breakpoints can be added. The
port_calls option returns the goal
information for these ports, in the
same order
priority 1..12 waking priority
run_priority 1..12 execution priority when woken
skip on, off procedure will be traced,
but its children will not
spy on, off procedure has a spypoint
stability static,dynamic is the procedure dynamic?
tool on, off tool property
type built-in,user type of predicate
visibility local,exported module scope
reexported,
imported
source_file an atom the file where defined
source_line an integer starting line number in the file
source_offset an integer byte offset at which the procedure
definition starts in its source file
The possible values of leash and their meanings are:
----------------------------------------------------- | Values Description | |-------------------------------------------------- | | stop procedure ports are printed and the | | debugger stops on them | | print procedure ports are printed and the | | debugger does not stop on them | | notrace procedure ports will not be shown, but | | its childrens's ports will | -----------------------------------------------------|
