annotate lisp/fontl-hooks.el @ 4477:e34711681f30
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.

24 ;;; Synched up with: FSF 19.30. (font-lock.el) | |
25 | |
26 ;;; Commentary: | |
27 | |
28 ;; The reason for the existence of this file is so that modes can | |
29 ;; call `font-lock-set-defaults' without worrying about whether | |
30 ;; font-lock is loaded. We don't autoload this from font-lock.el | |
31 ;; because loading font-lock.el automatically turns font-lock on. | |
32 | |
33 ;;; Code: | |
34 | |
35 (defun font-lock-set-defaults (&optional explicit-defaults) | |
36 "Set fontification defaults appropriately for this mode. | |
37 Sets `font-lock-keywords', `font-lock-keywords-only', `font-lock-syntax-table', | |
38 `font-lock-beginning-of-syntax-function' and | |
39 `font-lock-keywords-case-fold-search'. | |
40 | |
41 If `font-lock-defaults' is currently set, it is used. Otherwise, the | |
42 symbol naming the major mode is examined for a `font-lock-defaults' | |
43 property. If that is not present, but a variable `foo-mode-font-lock-keywords' | |
44 is, the value of that variable is used as the default for | |
45 `font-lock-keywords'. Various other backward-compatible behaviors also | |
46 exist -- if you're curious, look at the source. | |
47 | |
48 The value of `font-lock-maximum-decoration' is used to determine which | |
49 set of keywords applies, if more than one exists. | |
50 | |
51 This will also put the buffer into Font Lock mode if any keywords exist | |
52 and if auto-fontification is called for, as determined by | |
53 `font-lock-auto-fontify', `font-lock-mode-enable-list', and | |
54 `font-lock-mode-disable-list'. | |
55 | |
56 Calling this function multiple times in the same buffer is safe -- this | |
57 function keeps track of whether it has already been called in this | |
58 buffer, and does nothing if so. This allows for multiple ways of getting | |
59 Font Lock properly initialized in a buffer, to deal with existing major | |
60 modes that do not call this function. (For example, Font Lock adds this | |
61 function to `find-file-hooks'.) | |
62 | |
63 Major modes that have any font-lock defaults specified should call this | |
64 function during their initialization process, after they have set | |
65 the variable `major-mode'. | |
66 | |
67 If EXPLICIT-DEFAULTS is t, this function will not check whether it | |
68 has already been run in this buffer, and will always do the full | |
69 computation. | |
70 | |
71 If EXPLICIT-DEFAULTS is not nil and not t, it should be something | |
72 that is allowable as a value for `font-lock-defaults' and will be | |
73 used to initialize the Font Lock variables." | |
