@appendix Emacs 21.3 Antinews
|
|
|
|
For those users who live backwards in time, here is information about
|
|
downgrading to Emacs version 21.3. We hope you will enjoy the greater
|
|
simplicity that results from the absence of many newer features.
|
|
|
|
@itemize @bullet
|
|
@item
|
|
The input methods for Emacs are included in a separate distribution
|
|
called ``Leim''. To use them, you must extract the Leim tar file on
|
|
top of the Emacs distribution, into the same directory, before you
|
|
build Emacs.
|
|
|
|
@item
|
|
The file position and line number information is now at the end
|
|
of the mode line.
|
|
|
|
@item
|
|
When a file is managed with version control, the command @kbd{C-x C-q}
|
|
(whose general meaning is to make a buffer read-only or writable) now
|
|
does so by checking the file in or out. Checking the file out makes
|
|
the buffer writable; checking it in makes the buffer read-only (at
|
|
least with RCS).
|
|
|
|
You can still use @kbd{C-x v v} to do these operations if you wish;
|
|
its meaning is unchanged. If you want to control the buffer's
|
|
read-only flag without performing any version control operation,
|
|
use @kbd{M-x toggle-read-only}.
|
|
|
|
@item
|
|
Filesets are not supported.
|
|
|
|
@item
|
|
For simplicity, windows always have fringes. We wouldn't want
|
|
to in-fringe anyone's windows. Likewise, horizontal scrolling
|
|
always works the same automatic way.
|
|
|
|
@item
|
|
When you are logged in as root, all files now give you writable
|
|
buffers in Emacs reflecting the fact that you can write any files.
|
|
|
|
@item
|
|
Unicode support and unification between Latin-@var{n} character
|
|
sets have been removed. Cutting and pasting X selections does not
|
|
support ``extended segments'' so there are certain coding systems
|
|
it cannot handle.
|
|
|
|
@item
|
|
@kbd{C-w} in an incremental search always grabs an entire word
|
|
into the search string. More precisely, it grabs text through
|
|
the next end of a word.
|
|
|
|
@item
|
|
Yanking now preserves all text properties that were in the killed
|
|
text. The variable @code{yank-excluded-properties} has no meaning.
|
|
|
|
@item
|
|
Occur mode, Info mode, and Comint-derived modes now control
|
|
fontification in their own way, and @kbd{M-x font-lock-mode}
|
|
has nothing to do with it. To control fontification in Info
|
|
mode, use the variable @code{Info-fontify}.
|
|
|
|
@item
|
|
In Dired's @kbd{!} command, @samp{*} and @samp{?} now
|
|
cause substitution of the file names wherever they appear---not
|
|
only when they are surrounded by whitespace.
|
|
|
|
@item
|
|
Minibuffer completion commands now always complete the entire
|
|
minibuffer contents, just as if you had typed them at the end
|
|
of the minibuffer, no matter where point is actually located.
|
|
|
|
@item
|
|
An unquoted @samp{$} in a file name is now an error, if the following
|
|
name is not recognized as an environment variable. Thus,
|
|
the file name @file{foo$bar} would probably be an error. Meanwhile,
|
|
the @code{setenv} command does not expand @samp{$} at all.
|
|
|
|
@item
|
|
Commands to set the mark at a place away from point, including
|
|
@kbd{M-@@}, @kbd{M-h}, etc., don't do anything special when you repeat
|
|
them. In most cases, typing these commands multiple times is
|
|
equivalent to using them once. @kbd{M-h} does not use its numeric
|
|
argument.
|
|
|
|
@item
|
|
@kbd{C-@key{SPC} C-@key{SPC}} has no special meaning and neither does
|
|
@kbd{C-u C-x C-x}.
|
|
|
|
@item
|
|
There is no horizontal-bar cursor.
|
|
|
|
@item
|
|
The faces @code{minibuffer-prompt} and @code{mode-line-inactive}
|
|
do not exist, and the features they control don't exist either.
|
|
|
|
@item
|
|
The default value of @code{keyboard-coding-system} is always @code{nil}.
|
|
Emacs does not set it based on your locale settings.
|
|
If you want some other value, you must set it yourself.
|
|
|
|
@item
|
|
SGML mode does not handle XML syntax, and does not have indentation support.
|
|
|
|
@item
|
|
The @kbd{C-h} subcommands have been rearranged---especially those that
|
|
display specific files. Type @kbd{C-h C-h} to see a list of these
|
|
commands; that will show you what is different.
|
|
|
|
@item
|
|
Emacs does not read @file{~/.abbrev_defs} automatically; if you want
|
|
to load abbrev definitions from a file, you must always do so
|
|
explicitly.
|
|
|
|
@item
|
|
The @samp{--fullwidth}, @samp{--fullheight} and @samp{--fullscreen}
|
|
command line options are not supported.
|
|
|
|
@item
|
|
The @samp{--geometry} option now entirely applies only to the initial
|
|
frame.
|
|
|
|
@item
|
|
Many commands have been removed from the menus or rearranged.
|
|
|
|
@item
|
|
Many @code{etags} features for customizing parsing using regexps
|
|
have been removed.
|
|
|
|
@item
|
|
The CUA, ido, table, tramp, reveal, ruler-mode, and ibuffer packages
|
|
have been removed. So has the spreadsheet, SES, and the algebraic
|
|
calculator, Calc. (We distribute Calc separately.)
|
|
|
|
@item
|
|
The kmacro package has been removed. To start a keyboard macro you
|
|
must use @kbd{C-x (}; to end one, @kbd{C-x )}; to execute the last
|
|
one, @kbd{C-x e}.
|
|
|
|
@item
|
|
To keep up with decreasing computer memory capacity and disk space, many
|
|
other functions and files have been eliminated in Emacs 21.3.
