All predicatesShow sourcethreadutil.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.

Source threads
List currently known threads with their status.
Source join_threads
Join all terminated threads.
Source interactor is det
Source interactor(?Title) is det
Run a Prolog toplevel in another thread with a new console window. If Title is given, this will be used as the window title.
Source thread_run_interactor
Attach a console and run a Prolog toplevel in the current thread.
Source thread_has_console is semidet
True when the calling thread has an attached console.

- attach_console/0
Source attach_console is det
Source attach_console(?Title) is det
Create a new console and make the standard Prolog streams point to it. If not provided, the title is built using the thread id. Does nothing if the current thread already has a console attached.
Source open_console(+Title, -In, -Out, -Err) is det[private]
Open a new console window and unify In, Out and Err with the input, output and error streams for the new console.
Source 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.

Source enable_line_editing(+In, +Out, +Err) is det[private]
Enable line editing for the console. This is by built-in for the Windows console. We can also provide it for the X11 xterm(1) based console if we use the BSD libedit based command line editor.
Source detach_console(+ThreadId) is det[private]
Destroy the console for ThreadId.
Source tspy(:Spec) is det
Source tspy(:Spec, +ThreadId) is det
Trap the graphical debugger on reaching Spec in the specified or any thread.
Source tdebug is det
Source tdebug(+Thread) is det
Enable debug-mode, trapping the graphical debugger on reaching spy-points or errors.
Source tnodebug is det
Source tnodebug(+Thread) is det
Disable debug-mode in all threads or the specified Thread.
Source tprofile(+Thread) is det
Profile the operation of Thread until the user hits a key.
Source init_pce[private]
Make sure XPCE is running if it is attached, so we can use the graphical display using in_pce_thread/1.
Source interactor is det
Source interactor(?Title) is det
Run a Prolog toplevel in another thread with a new console window. If Title is given, this will be used as the window title.
Source attach_console is det
Source attach_console(?Title) is det
Create a new console and make the standard Prolog streams point to it. If not provided, the title is built using the thread id. Does nothing if the current thread already has a console attached.
Source tspy(:Spec) is det
Source tspy(:Spec, +ThreadId) is det
Trap the graphical debugger on reaching Spec in the specified or any thread.
Source tdebug is det
Source tdebug(+Thread) is det
Enable debug-mode, trapping the graphical debugger on reaching spy-points or errors.
Source tnodebug is det
Source tnodebug(+Thread) is det
Disable debug-mode in all threads or the specified Thread.
