B.6 Readline Interaction

The following predicates are available if current_prolog_flag(readline, true) succeeds. They allow for direct interaction with the GNU readline library. See also readline(3)

rl_read_init_file(+File)

Read a readline initialisation file. Readline by default reads /.inputrc. This predicate may be used to read alternative readline initialisation files.

rl_add_history(+Line)

Add a line to the Control-P/Control-N history system of the readline library.
