experimental command window widget with server loop
This changeset provides a new experimental proof-of-concept
cross-platform command window. It is intended to demonstrate how
communication between the GUI command window and the Octave
interpreter can work when the GUI is completely responsible for user
input instead of having the interpreter wait for input inside
readline.
This initial implementation uses a simple text box for input and a
separate text edit area for output. This design is not intended to be
the final arrangement, but was easy to implement for demonstration
purposes. These changes also make it possible to run the command-line
version of Octave in a similar client-server mode with a function
gathering input in one thread and the Octave intepreter running in
another.
The new command window is not intended to provide a general-purpose
terminal window. So running something like "system ('emacs')" will not
bring up an instance of Emacs running in the command window. This
also means that it will no longer be possible to use an external
output pager such as "less" in the command window. OTOH, it is also
no longer necessary to fork and exec a separate process on some Unixy
systems when Octave starts solely to give up the controlling terminal
so that "less" will function properly.
With the new terminal window, it is now possible to start Octave in
command line mode and later open the GUI desktop window and then
return to the command line when the GUI window is closed.
Some things that need to be finished:
* Merge the input and output windows so that command input and
output are interleaved as they are in a normal command window.
* Provide real readline command editing in the GUI command window and at
the client-server CLI prompt. We can use the readline callback
interface for the GUI and the normal readline interface for the
CLI. With this design, the command widget and the CLI front end
hold a copy of the command history. They do not need to
communicate with the interpreter to navigate the command history.
* Create interpreter_event messages for handling user input so that
the interpreter can ask the GUI to gather user input for functions
like "input".
* Consider passing results back to the command widget as
octave_value objects and allowing the command widget to format and
display them instead of passing formatted text from the
interpreter to the command widget.
* Provide an output pager feature for the GUI command window? Maybe
this feature is not necessary since we have scroll bars in the GUI
and we can also have the GUI ask the user whether to display
output if it is large.
ChangeLog:
* options-usage.h (usage_string, octave_print_verbose_usage_and_exit):
Include --experimental-terminal-widget in list of options.
(EXPERIMENTAL_TERMINAL_WIDGET_OPTION): New macro.
(long_opts): Include "experimental-terminal-widget" in the list.
* octave.h, octave.cc (cmdline_options::cmdline_options):
Handle EXPERIMENTAL_TERMINAL_WIDGET_OPTION.
(cmdline_options::m_experimental_terminal_widget): New data member.
(application::experimental_terminal_widget,
cmdline_options::experimental_terminal_widget
interpreter::experimental_terminal_widget): New functions.
* main.in.cc (fork_and_exec): New static variable.
(main): Don't fork and exec if argv includes
--experimental-terminal-widget.
* interpreter-qobject.h, interpreter-qobject.cc
(interpreter_qobject::pause, interpreter_qobject::stop,
interpreter_qobject::resume): New functions.
(interpreter_qobject::execute): Don't set prompt strings here if using
the new terminal widget. If using the new terminal widget, call
interpreter::shutdown and emit the shutdown_finished signal after
interpreter::execute returns.
(interpreter_qobject::shutdown): Don't do anything if using the new
terminal widget.
* main-window.h, main-window.cc (main_window::handle_octave_ready):
Set interpreter prompt strings here if using the new terminal widget.
(main_window::close_gui_signal): New signal.
(main_window::closeEvent): If using new terminal widget and shutdown
is confirmed, simply emit close_gui_signal.
(main_window::construct_octave_qt_link): If using new terminal widget,
connect qt_interpreter_events::interpreter_output_signal to the
terminal_dock_widget::interpreter_output slot and the
qt_interpreter_events::update_prompt_signal to the
terminal_dock_widget::update_prompt slot.
* octave-qobject.h, octave-qobject.cc
(base_qobject::interpreter_pause, base_qobject::interpreter_stop,
base_qobject::interpreter_resume): New functions.
(base_qobject::base_qobject): If using new terminal widget:
Don't connect interpreter_qobject::execution_finished signal to
octave_qobject::handle_interpreter_execution_finished slot
Don't connect octave_qobject::request_interpreter_shutdown signal to
the interpreter_qobject::shutdown slot.
Do connect the qt_interpreter_events::start_gui_signal signal to the
octave_qobject::start_gui slot and simply reload settings and call
qt_application::setQuitOnLastWindowClosed. There is no need to create
the main window here.
(base_qobject::exec): If using new terminal widget, wait for main
thread to finish after qt_application::exec returns.
(base_qojbect::experimental_terminal_widget,
base_qobject::gui_running): New functions.

base_qojbect::interpreter_pause, base_qojbect::interpreter_stop,
base_qojbect::interpreter_resume): New slots.
(base_qojbect::handle_interpreter_execution_finished): Do nothing if
using new terminal widget.
* qt-application.cc (qt_application::start_gui_p): Return dummy value
if using new terminal widget.

use new terminal widget. If using new terminal widget, connect
command_widget::interpreter_event signals to
terminal_dock_widget::interpreter_event signals.
(terminal_dock_widget::interpreter_output,
terminal_dock_widget::update_prompt): New slots.
(terminal_dock_widget::update_prompt_signal,
terminal_dock_widget::interpreter_output_signal): New signals.
* event-manager.h, event-manager.cc (Fdesktop): New function.
(interpreter_events::start_gui, interpreter_events::close_gui,
