font changes etc.; some 21.4 changes
mule/mule-msw-init-late.el: Specify charset->windows-registry conversion.
mule/mule-x-init.el: Delete extra mule font additions here. Put them in faces.c.
cl-macs.el: Document better.
font-lock.el: Move Lisp function regexp to lisp-mode.el.
lisp-mode.el: Various indentation fixes:
Handle flet functions better.
Handle argument lists in defuns and flets.
Handle quoted lists, e.g. property lists -- don't indent like
function calls. Distinguish between lambdas and other lists.
lisp-mode.el: Handle this form.
faces.el, font-menu.el, font.el, gtk-faces.el, msw-faces.el, msw-font-menu.el, x-faces.el, x-init.el: Major overhaul of face-handling code:
-- Fix lots of bogus code in msw-faces.el, msw-font-menu.el,
font-menu.el that was "truenaming" font specs -- i.e. in the
process of frobbing a particular field in a general user-specified
font spec with wildcarded fields, sticking in particular values
for all the remaining wildcarded fields. This bug was rampant
everywhere except in x-faces.el (the oldest and only correctly
written code). This also means that we need to work with font
names at all times and not font instances, because a font instance
is essentially a truenamed font.
-- Total rewrite of extremely junky code in msw-faces.el. Work
with names as well as font instances, and return names; stop
truenaming when canonicalizing and frobbing; fix handling of the
combined style field, i.e. weight/slant (also fixed in font.el).
-- Totally rewrite the frobbing functions in faces.el. This time,
we frob all the instantiators rather than just computing a single
instance value and working backwards. That way, e.g., `bold' will
work for all charsets that have bold available, rather than only
for whatever charset was part of the computed font instance
(another example of the truename virus). Also fix up code to look
at the fallbacks (all of them) when no global value present, so we
don't need to put something in the global value. Intelligently
handle a request to frob a buffer locale, rather than signalling
an error. When frobbing instantiators, try hard to figure out
what device type is associated with them, and frob each according
to its own proper device type. Correctly handle inheritance
vectors given as instantiators. Preserve existing tags when
putting back frobbed instantiators. Extract out general
specifier-frobbing code into specifier.el. Document everything
cleanly. Do lots of other things better, etc.
-- Don't duplicatively set a global specification for the default
font -- it's already in the fallback and we no longer need a
default global specification present. Delete various code in
x-faces.el and msw-faces.el that duplicated the lists of fonts in
faces.c.
-- init-global-faces was not being called at all under MS Windows!
Major bogosity. That caused device-specific values to get stuck
into all the fonts, making it very hard to change them -- setting
global specs caused nothing to happen.
-- Correct weight names in font.el.
-- Lots more font fixups in objects*.c.
Printer.el: Warning fix.
specifier.el: Add more args to map-specifier.
Add various "heuristic" specifier functions to aid in creation of
specifier-munging code such as in faces.el.
subr.el: New functions.
lwlib.c: Fix warning.
config.inc.samp: Clean up, add args to control fastcall (not yet supported! the
changes needed are in another ws of mine), profile support, vc6
support, union-type.
xemacs.dsp, xemacs.mak: Semi-major overhaul.
Fix bug where dump-id was always getting recomputed, forcing a
redump even when nothing changed.
Add support for fastcall. Support edit-and-continue (on by
default) with vc6. Use incremental linking when doing a debug
compilation. Add support for profiling.
Consolidate the various debug flags.
Partial support for "batch-compiling" -- compiling many files on a
single invocation of the compiler. Doesn't seem to help that much
for me, so it's not finished or enabled by default.
Remove HAVE_MSW_C_DIRED, we always do.
Correct some sloppy use of directories.
s/cygwin32.h: Allow pdump to work under Cygwin (mmap is broken, so need to undefine
HAVE_MMAP).
s/win32-common.h, s/windowsnt.h: Support for fastcall. Add WIN32_ANY for identifying all Win32
variants (Cygwin, native, MinGW). Both of these are properly used
in another ws.
alloc.c, balloon-x.c, buffer.c, bytecode.c, callint.c, cm.c, cmdloop.c, cmds.c, console-gtk.c, console-gtk.h, console-msw.c, console-msw.h, console-stream.c, console-stream.h, console-tty.c, console-tty.h, console-x.c, console-x.h, console.c, console.h, device-gtk.c, device-msw.c, device-tty.c, device-x.c, device.c, device.h, devslots.h, dialog-gtk.c, dialog-msw.c, dialog-x.c, dialog.c, dired-msw.c, editfns.c, emacs.c, event-Xt.c, event-gtk.c, event-msw.c, event-stream.c, event-tty.c, event-unixoid.c, events.c, extents.c, extents.h, faces.c, fileio.c, fns.c, frame-gtk.c, frame-msw.c, frame-tty.c, frame-x.c, frame.c, frame.h, glyphs-eimage.c, glyphs-gtk.c, glyphs-msw.c, glyphs-widget.c, glyphs-x.c, glyphs.c, glyphs.h, gui-gtk.c, gui-msw.c, gui-x.c, gui.c, gutter.c, input-method-xlib.c, intl-encap-win32.c, intl-win32.c, keymap.c, lisp.h, macros.c, menubar-gtk.c, menubar-msw.c, menubar-x.c, menubar.c, menubar.h, minibuf.c, mule-charset.c, nt.c, objects-gtk.c, objects-gtk.h, objects-msw.c, objects-msw.h, objects-tty.c, objects-tty.h, objects-x.c, objects-x.h, objects.c, objects.h, postgresql.c, print.c, process.h, redisplay-gtk.c, redisplay-msw.c, redisplay-output.c, redisplay-tty.c, redisplay-x.c, redisplay.c, redisplay.h, scrollbar-gtk.c, scrollbar-msw.c, scrollbar-x.c, scrollbar.c, select-gtk.c, select-msw.c, select-x.c, select.c, signal.c, sound.c, specifier.c, symbols.c, syntax.c, sysdep.c, syssignal.h, syswindows.h, toolbar-common.c, toolbar-gtk.c, toolbar-msw.c, toolbar-x.c, toolbar.c, unicode.c, window.c, window.h: The following are the major changes made:
(1) Separation of various header files into an external and an
internal version, similar to the existing separation of process.h
and procimpl.h. Eventually this should be done for all Lisp
objects. The external version has the same name as currently; the
internal adds -impl. The external file has XFOO() macros for
objects, but the structure is opaque and defined only in the
internal file. It's now reasonable to move all prototypes in
lisp.h into the appropriate external file, and this should be
done. Currently, separation has been done on extents.h,
objects*.h, console.h, device.h, frame.h, and window.h.
For c/d/f/w, the most basic properties are available in the
external header file, with the macros resolving to functions. In
the internal header file, the macros are redefined to directly
access the structure. Also, the global MARK_FOO_CHANGED macros
have been made into functions so that they can be accessed without
needing to include lots of -impl headers -- they are used in
almost exclusively in non-time-critical functions, and take up
enough time that the function overhead will be negligible.
Similarly, the function overhead from making the basic properties
mentioned above into functions is negligible, and code that does
heavy accessing of c/d/f/w structures inevitably ends up needing
the internal header files, anyway.
(2) More face changes.
-- Major rewrite of objects-msw.c. Now handles wildcard specs
properly, rather than "truenaming" (or even worse, signalling an
error, which previously happened with some of the fallbacks if you
tried to use them in make-font-instance!).
-- Split charset matching of fonts into two stages -- one to find
a font specifically designed for a particular charset (by
examining its registry), the second to find a Unicode font that
can support the charset. This needs to proceed as two complete,
separate instantiations in order to work properly (otherwise many
of the fonts in the HELLO page look wrong). This should also make
it easy to support iso10646 (Unicode) fonts under X.
-- All default values for fonts are now completely specified in
the fallbacks. Stuff from mule-x-init.el has all been moved here,
merged with the existing specs, and totally rethought so you get
sensible results. (HELLO now looks much better!).
-- Generalize the "default X/GTK device" stuff into a
per-device-type "default device".
-- Add mswindows-{set-}charset-registry. In time,
charset<->code-page conversion functions will be removed.
-- Wrap protective code around calls to compute device specifier tags,
and do this computation before calling the face initialization code
because the latter may need these tags to be correctly updated.
(3) Other changes.
EmacsFrame.c, glyphs-msw.c, eval.c, gui-x.c, intl-encap-win32.c, search.c, signal.c, toolbar-msw.c, unicode.c: Warning fixes.
config.h.in: #undefs meant to be frobbed by configure *MUST* go inside of
#ifndef WIN32_NO_CONFIGURE, and everything else *MUST* go outside!
eval.c: Let detailed backtraces be detailed.
specifier.c: Don't override user's print-string-length/print-length settings.
glyphs.c: New function image-instance-instantiator.
config.h.in, sysdep.c: Changes for fastcall.
sysdep.c, nt.c: Fix up a previous botched patch that tried to add support for both
EEXIST and EACCES. IF THE BOTCHED PATCH WENT INTO 21.4, THIS FIXUP
NEEDS TO GO IN, TOO.
search.c: Fix *evil* crash due to incorrect synching of syntax-cache code
with 21.1. THIS SHOULD GO INTO 21.4.

0 | 1 This directory contains files of elisp that customize Emacs for certain |
2 terminal types. | |
3 | |
4 When Emacs starts, it checks the TERM environment variable to see what type | |
5 of terminal the user is running on, checks for an elisp file named | |
6 "term/${TERM}.el", and if one exists, loads it. If that doesn't yield a file | |
7 that exists, the last hyphen and what follows it is stripped. If that doesn't | |
8 yield a file that exists, the previous hyphen is stripped, and so on until all | |
9 hyphens are gone. For example, if the terminal type is `aaa-48-foo', Emacs | |
10 will try first `term/aaa-48-foo.el', then `term/aaa-48.el' and finally | |
11 `term/aaa.el'. | |
12 | |
13 When writing terminal packages, there are some things it is good to keep in | |
14 mind. | |
15 | |
16 First, about keycap names. Your terminal package can create any keycap | |
17 cookies it likes, but there are good reasons to stick to the set recognized by | |
18 the X-windows code whenever possible. The key symbols recognized by Emacs | |
19 are listed in src/term.c; look for the string `keys' in that file. | |
20 | |
21 For one thing, it means that you'll have the same Emacs key bindings on in | |
22 terminal mode as on an X console. If there are differences, you can bet | |
23 they'll frustrate you after you've forgotten about them. | |
24 | |
25 For another, the X keysms provide a standard set of names that Emacs knows | |
26 about. It tries to bind many of them to useful things at startup, before your | |
27 .emacs is read (so you can override them). In some ways, the X keysym standard | |
28 is a admittedly poor one; it's incomplete, and not well matched to the set of | |
29 `virtual keys' that UNIX terminfo(3) provides. But, trust us, the alternatives | |
30 were worse. | |
31 | |
32 This doesn't mean that if your terminal has a "Cokebottle" key you shouldn't | |
33 define a [cokebottle] keycap. But if you must define cookies that aren't in | |
34 that set, try to pattern them on the standard terminfo variable names for | |
35 clarity; also, for a fighting chance that your binding may be useful to someone | |
36 else someday. | |
37 | |
38 For example, if your terminal has a `find' key, observe that terminfo | |
39 supports a key_find capability and call your cookie [key-find]. | |
40 | |
41 Here is a complete list, with corresponding X keysyms. | |

150 | |
151 (1) The terminfo documentation says this may be the 'insert character' or | |
152 `enter insert mode' key. Accordingly, key_ic is mapped to the `insertchar' | |
153 keysym if there is also a key_dc key; otherwise it's mapped to `insert'. | |
154 The presumption is that keyboards with `insert character' keys usually | |
155 have `delete character' keys paired with them. | |
156 | |
157 (2) If there is no key_next key but there is a key_npage key, key_npage | |
158 will be bound to the `next' keysym. If there is no key_previous key but | |
159 there is a key_ppage key, key_ppage will be bound to the `previous' keysym. | |
160 | |
161 (3) Sorry, these are not exact but they're the best we can do. | |
162 | |
163 (4) The uses of the "k0" capability are inconsistent; sometimes it | |
164 describes F10, whereas othertimes it describes F0 and "k;" describes F10. | |
165 Emacs attempts to politely accommodate both systems by testing for | |
166 "k;", and if it is present, assuming that "k0" denotes F0, otherwise F10. | |
167 ----------------------------------------------------------------------------- | |
168 | |
169 The following X keysyms do *not* have terminfo equivalents. These are | |
170 the cookies your terminal package will have to set up itself, if you want them: | |
171 | |
172 break | |
173 system | |
174 user | |
175 kp-backtab | |
176 kp-space | |
177 kp-tab | |
178 kp-f1 | |
179 kp-f2 | |
180 kp-f3 | |
181 kp-f4 | |
182 kp-multiply | |
183 kp-add | |
184 kp-separator | |
185 kp-subtract | |
186 kp-decimal | |
187 kp-divide | |
188 kp-0 | |
189 kp-2 | |
190 kp-4 | |
191 kp-6 | |
192 kp-8 | |
193 kp-equal | |
194 | |
195 In general, you should not bind any of the standard keysym names to | |
196 functions in a terminal package. There's code in loaddefs.el that does that; | |
197 the less people make exceptions to that, the more consistent an interface Emacs | |
198 will have across different keyboards. Those exceptions should go in your | |
199 .emacs file. | |
200 | |
201 Finally, if you're using a USL UNIX or a Sun box or anything else with the | |
202 USL version of curses(3) on it, bear in mind that the original curses(3) had | |
203 (and still has) a very much smaller set of keycaps. In fact, the reliable | |
204 ones were just the arrow keys and the first ten function keys. If you care | |
205 about making your package portable to older Berkeley machines, don't count on | |
206 the setup code to bind anything else. | |
207 | |
208 If your terminal's arrow key sequences are so funky that they conflict with | |
209 normal Emacs key bindings, the package should set up a function called | |
210 (enable-foo-arrow-keys), where `foo' becomes the terminal name, and leave | |
211 it up to the user's .emacs file whether to call it. | |
212 | |
213 Before writing a terminal-support package, it's a good idea to read the | |
214 existing ones and learn the common conventions. |
