* doc/emacs/killing.texi (Clipboard): Document clipboard manager. * doc/lispref/windows.texi (Basic Windows, Coordinates and Windows) (Coordinates and Windows): * display.texi (Refresh Screen, Line Height, Face Attributes) (Overlay Arrow, Beeping, Glyphless Chars): Likewise. * doc/lispref/frames.texi (Frames): Remove little-used "terminal frame" and "window frame" terminology. (Frame Parameters, Font and Color Parameters, Initial Parameters) (Size and Position, Visibility of Frames): Callers changed. (Frames): Clarify which terminals in framep are graphical. (Initial Parameters): --geometry is not the only option which adds to initial-frame-alist. (Position Parameters): Note that icon-left and icon-top are for old window managers only. (Size Parameters): Sizes are in characters even on graphical displays. (Management Parameters): Note that window-id and outer-window-id can't really be changed, and that auto-raise isn't always obeyed. (Cursor Parameters): Document cursor-type explicitly. (Size and Position): The aliases set-screen-height and set-screen-width have been deleted. (Visibility of Frames): Mention "minimization". * doc/lispref/os.texi (Startup Summary): Minor clarifications. (Startup Summary, Suspending Emacs): Standardize on "text terminal" terminology.

For those users who live backwards in time, here is information about
|
|
downgrading to Emacs version 22.3. We hope you will enjoy the greater
|
|
simplicity that results from the absence of many Emacs @value{EMACSVER}
|
|
features.

|
|
@section Old Lisp Features in Emacs 22
|
|
|
|
@itemize @bullet
|
|
@item
|
|
The internal character representation used by Emacs is not longer
|
|
based on Unicode. In this representation, called @code{emacs-mule},
|
|
each character belongs to one and only one script. Emacs makes no
|
|
attempt to distinguish between ``similar'' characters occurring in
|
|
different scripts.
|
|
|
|
@item
|
|
The @code{^} interactive spec code, the function
|
|
@code{handle-shift-selection}, and the variable
|
|
@code{this-command-keys-shift-translated} have all been removed.
|
|
Shift-translated keys are no longer treated specially, making Emacs's
|
|
handling of keybindings much more consistent.
|
|
|
|
@item
|
|
Temporarily-active regions are not created by giving the variable
|
|
@code{transient-mark-mode} values of the form @code{(only
|
|
. @var{oldvar})}. We instead use a more complicated scheme:
|
|
setting @code{transient-mark-mode} to @code{only} enables Transient
|
|
Mark mode for the following command only, during which the value of
|
|
@code{transient-mark-mode} is set to @code{identity}; if it is still
|
|
@code{identity} at the end of the command, Transient Mark mode is
|
|
disabled.
|
|
|
|
@item
|
|
Many minibuffer functions, such as @code{read-file-name} and
|
|
@code{minibuffer-complete}, have been rewritten in C for greater
|
|
speed. The completion code has been considerably simplified; the
|
|
completion style can no longer be changed via
|
|
@code{completion-styles-alist}, and @code{completing-read} no longer
|
|
recognizes the special values @code{confirm-only} and
|
|
@code{confirm-after-completion} for its @var{require-match} argument.
|
|
|
|
@item
|
|
Emacs no longer supports explicitly-numbered groups in regular
|
|
expressions.
|
|
|
|
@item
|
|
The @code{permanent-local-hook} function property has no special
|
|
meaning.
|
|
|
|
@item
|
|
The @code{functionp} function now returns @code{t} for special forms.
|
|
|
|
@item
|
|
The @code{interactive-form} symbol property has no special meaning.
|
|
Once you supply a function with an interactive form, the only way to
|
|
change it is to redefine the function.
|
|
|
|
@item
|
|
The @code{ignore-errors} macro has been moved into the @code{cl}
|
|
package.
|
|
|
|
@item
|
|
Variables can now be both buffer-local and frame-local; buffer-local
|
|
bindings take precedence over frame-local bindings.
|
|
|
|
@item
|
|
Faces can no longer be remapped.
|
|
|
|
@item
|
|
Lisp programs now specify fonts by their names, which are strings
|
|
following the XLFD (X logical font descriptor) format. Fonts are no
|
|
longer represented using a special set of ``font'' data types. The
|
|
various functions that act on these data types, such as @code{fontp},
|
|
@code{font-spec}, and @code{list-fonts}, have all been deleted.
|
|
|
|
@item
|
|
Emacs does not recognize the @code{FontBackend} X resource and the
|
|
@code{font-backend} frame parameter. On the X Window System, fonts
|
|
are always drawn using the X core font driver.
|
|
|
|
@item
|
|
Display terminals are no longer represented using a ``terminal'' data
|
|
type; this is not necessary, because we have removed the ability to
|
|
display on graphical and text terminals simultaneously. For the same
|
|
reason, the @code{window-system} variable is no longer frame-local,
|
|
and the @code{window-system} function has been removed.
|
|
|
|
@item
|
|
The functions @code{list-system-processes} and
|
|
@code{process-attributes} have been removed. To get information about
|
|
system processes, call an external program, such as @command{ps}.
|
|
|
|
@item
|
|
The function @code{locate-user-emacs-file} and the variable
|
|
@code{user-emacs-directory} have been removed. Instead, use
|
|
hard-coded values pointing to @file{~/.emacs.d}.
|
|
|
|
@item
|
|
@code{vertical-motion} can no longer be told to move to a specific
|
|
column; it always puts point on the first column of a line.
|
|
|
|
@item
|
|
Windows no longer have parameters.
|
|
|
|
@item
|
|
The @code{display-buffer} function has been rewritten in C. Its
|
|
window-splitting heuristics are a little less sophisticated, and a
|
|
little less documented. Window-splitting is handled internally,
|
|
instead of using @code{split-window-preferred-function} (which has
|
|
been removed). Windows are never split horizontally; the variable
|
|
@code{split-width-threshold} has been removed.
|
|
|
|
@item
|
|
The @code{mode-name} variable now accepts only string values, and
|
|
cannot take the form of a mode-line construct.
|
|
|
|
@item
|
|
The behavior of @code{map-char-table} has changed. It calls the
|
|
mapping function for every single character in the table, instead of
|
|
using cons cells to represent contiguous character code ranges.
|
|
|
|
@item
|
|
Several keymaps have been eliminated: @code{input-decode-map},
|
|
@code{local-function-key-map}, @code{search-map},
|
|
@code{multi-query-replace-map}, and
|
|
@code{minibuffer-local-shell-command-map}.
|
|
|
|
@item
|
|
Many functions have been removed, including: @code{buffer-swap-text},
|
|
@code{emacs-init-time}, @code{emacs-uptime}, @code{use-region-p},
|
|
@code{region-active-p}, @code{start-file-process},
|
|
@code{process-lines}, @code{image-refresh},
|
|
@code{match-substitute-replacement}, @code{word-search-forward-lax},
|
|
and @code{word-search-backward-lax}.
|
|
|
|
@item
|
|
Many variables have been removed, including @code{read-circle},
|
|
@code{after-init-time} and @code{before-init-time},
|
|
@code{generate-autoload-cookie}, @code{file-local-variables-alist},
|
|
@code{replace-search-function} and @code{replace-re-search-function},
|
|
@code{inhibit-changing-match-data}, @code{wrap-prefix}, and
|
|
@code{line-prefix},
|
|
