port_profile(+Goal, ++Options)

Create a (box model) port profile for the given Goal execution

Goal: A callable goal (atom or compound term)
Options: A list of OptionName:OptionValue structures

Description

Executes Goal and creates a (box model) port profile for this execution. The ports are the ports as defined for the debugger's box model and include:

call: predicate invocation
exit: deterministic predicate success
fail: predicate failure
*exit: nondeterministic predicate success
redo: reentering a predicate on backtracking
next: going to the next clause of a predicate
else: going to an alternative within a predicate
leave: leaving a predicate with exit_block/1
delay: delaying a predicate
resume: reentering a predicate on waking

The available options are:

format (default:txt)

output format, txt or html

txt

prints an ascii table, taking width-option into account

html

prints an html table, taking border-option into account

raw

prints the raw results as lines of the form

		[M:F/A from PM:PF/PA, Port, Count].

if the show_caller-option is on, and

		[M:F/A, Port, Count].

if the show_caller-option is off. These are valid Prolog terms which can be read back using read/2.

border (default:0)

table border width for html output

output (default:default)

where to put the result: possible values are

file(File): where File is a file name
stream(Stream): where Stream is an Eclipse stream identifier
dir(Dir): where Dir is a directory in which files with generated names will be placed
default: either dir(profiler) for html format, or stream(output) otherwise

ports (default:all)

the atom 'all' or a list of port names

predicates (default:all)

the atom 'all' or 'spied_only'. The latter means that only predicates with a spy point have their ports counted.

show_caller (default:on)

whether to show and distinguish predicates by their calling predicate (on or off). This is the only option that affects data collection as well as presentation.

show_module (default:off)

whether to show the predicate's definition modules in the output table (on or off)

width (default:80)

page width for txt output

Note: Any choicepoints that are left behind by Goal will be cut, i.e. port_profile/2 behaves like once/1.
