annotate libinterp/corefcn/oct-stream.cc @ 22089:c2c668b3051b
use classes for octave application and interpreter
* main-cli.cc (main): Simplify using class objects.
* main-gui.cc (main): Likeiwse.
* octave.h, octave.cc (octave::cmdline_options, octave::application,
octave::cli_application, octave::embedded_application,
octave::interpreter): New classes. Replace ordinary functions and
static/global data with objects. Access global application data
through application object.
* octave-gui.h, octave-gui.cc (octave::gui_application): New class.
Replace ordinary functions and static/global data with objects.
* main-window.cc (main_window::m_app_context): New data member.
(main_window::main_window): Pass application object instead of
start_gui flag.
(main_window::construct_octave_qt_link): Pass m_app_context to
octave_qt_link constructor.
* octave-interpreter.h, octave-interpreter.cc
(octave_interpreter::m_app_context,
octave_interpreter::m_exit_status): New data members.
(octave_interpreter::execute): Use class object to start interpreter.
Save exit status.
* octave-qt-link.h, octave-qt-link.cc (octave_qt_link::m_app_context):
New data member.
(octave_qt_link::do_set_default_prompts): Make prompt settings
conditional on whether the GUI is running.
* input.h, input.cc (interactive, forced_interactive):
Delete global data.
* dirfns.cc, error.cc, input.cc, oct-stream.cc, pager.cc,
sighandlers.cc, sysdep.cc, toplev.cc, lex.ll: Access interactive and
forced_interactive through global application object.
