The internal character representation in Emacs is no longer
|
||||
Unicode-based; it is known as @code{emacs-mule}. This representation
|
||||
can handle several different variants of the same character, each one
|
||||
belonging to its own script. It marks each character with its script,
|
||||
to better discern them from one another.
|
||||
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'
|
||||
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 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.

The @code{^} interactive spec code has been removed, together with the
|

function @code{handle-shift-selection} and the variable

@code{this-command-keys-shift-translated}. Shift-translated keys are
|

no longer treated specially, making Emacs' handling of keybindings

that much more consistent.

@item
|

The @code{interactive-form} symbol property is no longer recognized.
|
||||
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
|
||||
Emacs no longer creates temporarily-active regions by giving the
|
||||
variable @code{transient-mark-mode} values of the form @code{(only
|
||||
. @var{oldvar})}. Instead, it uses a more slightly 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.
|

The @code{ignore-errors} macro has been moved into the @code{cl}
|

Many minibuffer functions, such as @code{read-file-name} and

||||
@code{minibuffer-complete}, have been rewritten in C. The completion
|

code has been considerably simplified; for instance, the completion

style cannot 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.

Explicitly numbered groups in regular expressions are no longer

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},

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 data type is not necessary, because Emacs can no longer
|
||||
type; this is not necessary, because we have removed the ability to
|
||||
display on graphical and text-only 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.

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.
