threadutil.pl -- Interactive thread utilities

This library provides utilities that are primarily intended for interactive usage in a threaded Prolog environment. It allows for inspecting threads, manage I/O of background threads (depending on the environment) and manipulating the debug status of threads.

threads

List currently known threads with their status.

join_threads

Join all terminated threads.

interactor

Run a Prolog toplevel in another thread with a new console window.

thread_has_console is semidet

True when the calling thread has an attached console.

See also: - attach_console/0

attach_console is det

Create an xterm-console and make the standard Prolog streams point to it.

xterm_args(-List) is nondet[multifile]

Multifile and dynamic hook that provides (additional) arguments for the xterm(1) process opened for additional thread consoles. Each solution must bind List to a list of atomic values. All solutions are concatenated using append/2 to form the final argument list.

The defaults set the colors to black-on-light-yellow, enable a scrollbar, set the font using Xft font pattern and prepares the back-arrow key.

tspy(:Spec) is det

tspy(:Spec, +ThreadId) is det
