listing

Outputs the definition of all dynamic predicates in the database.

Description

Outputs each of the dynamic predicates currently contained on the database. ie. all predicates created using assert/1 or asserta/1 or compiled as dynamic predicates.

The order in which the predicates are listed is undefined.

The individual clauses are output in indented format using writeclause/2.

No static predicates are output.

This predicate is sensitive to its module context (tool predicate, see @/2).

    yes.
    [eclipse]: assert(man(adam)), assert(woman(eve)),
    > assert((likes(X,Y):-man(X),woman(Y))).
    X = _g102
    Y = _g98
    yes.
    [eclipse]: listing.
    x .
    y(_g68):-
            write(_g68) .
