The Tcl/Tk interface includes an experimental terminal window based on Tcl/Tk. It is opened by using the (undocumented) predicate:
tk_terminal(Interp, TextWidget, InStream, OutStream, ErrStream).top.myterm, this predicate opens three
Prolog streams for which the text widget acts as a terminal.
There is also a library(tkconsol), making use of
tk_terminal/5, which switches the Prolog top level to a Tk
window. This is done by simply loading the library module.
