Don't determine whether to call general device-type code at startup,
rather decide in the device-specific code itself.
lisp/ChangeLog addition:
2008-07-07 Aidan Kehoe <kehoea@parhasard.net>
Patch to make it up to the device-specific code whether
various Lisp functions should be called during device creation,
not relying on the startup code to decide this. Also, rename
initial-window-system to initial-device-type (which makes more
sense in this scheme), always set it.
* startup.el (command-line):
Use initial-device-type, not initial-window-system; just call
#'make-device, leave the special behaviour to be done the first
time a console type is initialised to be decided on by the
respective console code.
* x-init.el (x-app-defaults-directory): Declare that it should be
bound.
(x-define-dead-key): Have the macro take a DEVICE argument.
(x-initialize-compose): Have the function take a DEVICE argument,
and use it when checking if various keysyms are available on the
keyboard.
(x-initialize-keyboard): Have the function take a DEVICE argument,
allowing device-specific keyboard initialisation.
(make-device-early-x-entry-point-called-p): New.
(make-device-late-x-entry-point-called-p): New. Rename
pre-x-win-initted, x-win-initted.
(make-device-early-x-entry-point): Rename init-pre-x-win, take the
call to make-x-device out (it should be called from the
device-creation code, not vice-versa).
(make-device-late-x-entry-point): Rename init-post-x-win, have it
take a DEVICE argument, use that DEVICE argument when working out
what device-specific things need doing. Don't use
create-console-hook in core code.
* x-win-xfree86.el (x-win-init-xfree86): Take a DEVICE argument;
use it.
* x-win-sun.el (x-win-init-sun): Take a DEVICE argument; use it.
* mule/mule-x-init.el: Remove #'init-mule-x-win, an empty
function.
* tty-init.el (make-device-early-tty-entry-point-called-p): New.
Rename pre-tty-win-initted.
(make-device-early-tty-entry-point): New.
Rename init-pre-tty-win.
(make-frame-after-init-entry-point): New.
Rename init-post-tty-win to better reflect when it's called.
* gtk-init.el (gtk-early-lisp-options-file): New.
Move this path to a documented variable.
(gtk-command-switch-alist): Wrap the docstring to fewer than 79
columns.
(make-device-early-gtk-entry-point-called-p): New.
(make-device-late-gtk-entry-point-called-p): New.
Renamed gtk-pre-win-initted, gtk-post-win-initted to these.
(make-device-early-gtk-entry-point): New.
(make-device-late-gtk-entry-point): New.
Renamed init-pre-gtk-win, init-post-gtk-win to these.
Have make-device-late-gtk-entry-point take a device argument, and use
it; have make-device-early-gtk-entry-point load the GTK-specific
startup code, instead of doing that in C.
(init-gtk-win): Deleted, functionality moved to the GTK device
creation code.
(gtk-define-dead-key): Have it take a DEVICE argument; use this
argument.
(gtk-initialize-compose): Ditto.
* coding.el (set-terminal-coding-system):
Correct the docstring; the function isn't broken.
src/ChangeLog addition:
2008-07-07 Aidan Kehoe <kehoea@parhasard.net>
Patch to make it up to the device-specific code whether
various Lisp functions should be called during device creation,
not relying on the startup code to decide this. Also, rename
initial-window-system to initial-device-type (which makes more
sense in this scheme), always set it.
* redisplay.c (Vinitial_device_type): New.
(Vinitial_window_system): Removed.
Rename initial-window-system to initial-device type, making it
a stream if we're noninteractive. Update its docstring.
* device-x.c (Qmake_device_early_x_entry_point,
Qmake_device_late_x_entry_point): New.
Rename Qinit_pre_x_win, Qinit_post_x_win.
(x_init_device): Call #'make-device-early-x-entry-point earlier,
now we rely on it to find the application class and the
app-defaults directory.
(x_finish_init_device): Call #'make-device-late-x-entry-point with
the created device.
(Vx_app_defaults_directory): Always make this available, to
simplify code in x-init.el.
* device-tty.c (Qmake_device_early_tty_entry_point): New.
Rename Qinit_pre_tty_win, rename Qinit_post_tty_win and move to
frame-tty.c as Qmake_frame_after_init_entry_point.
(tty_init_device): Call #'make-device-early-tty-entry-point before
doing anything.
* frame-tty.c (Qmake_frame_after_init_entry_point): New.
* frame-tty.c (tty_after_init_frame): Have it call the
better-named #'make-frame-after-init-entry-point function
instead of #'init-post-tty-win (since it's called after frame, not
device, creation).
* device-msw.c (Qmake_device_early_mswindows_entry_point,
Qmake_device_late_mswindows_entry_point): New.
Rename Qinit_pre_mswindows_win, Qinit_post_mswindows_win.
(mswindows_init_device): Call
#'make-device-early-mswindows-entry-point here, instead of having
its predecessor call us.
(mswindows_finish_init_device): Call
#'make-device-early-mswindows-entry-point, for symmetry with the
other device types (though it's an empty function).
* device-gtk.c (Qmake_device_early_gtk_entry_point,
Qmake_device_late_gtk_entry_point): New.
Rename Qinit_pre_gtk_win, Qinit_post_gtk_win.
(gtk_init_device): Call #'make-device-early-gtk-entry-point; don't
load ~/.xemacs/gtk-options.el ourselves, leave that to lisp.
(gtk_finish_init_device): Call #'make-device-late-gtk-entry-point
with the created device as an argument.
