el_wrap/1

Availability::- use_module(library(editline)).(can be autoloaded)

[det]el_wrap(+Options)

Enable using editline on the standard user streams if user_input is connected to a terminal. This is the high level predicate used for most purposes. The remainder of the library interface deals with low level predicates that allows for applying and programming libedit in non-standard situations.

The library is registered with ProgName set to swipl (see el_wrap/4).
