* Installation Changes in Emacs 25.1
|
||
|
||
+++
|
||
** Building Emacs now requires C99 or later.
|
||
|
||
** Building Emacs now requires GNU make, version 3.81 or later.
|
||
|
||
** By default, Emacs no longer works on IRIX. We expect that Emacs
|
||
users are not affected by this, as SGI stopped supporting IRIX in
|
||
December 2013. If you are affected, please send a bug report. You
|
||
should be able to work around the problem either by porting the Emacs
|
||
undumping code to GCC under IRIX, or by configuring --with-wide-int,
|
||
or by sticking with Emacs 24.4.
|
||
|
||
** 'configure' now prefers gnustep-config when configuring GNUstep.
|
||
If gnustep-config is not available, the old heuristics are used.
|
||
|
||
---
|
||
** The configure option '--with-pkg-config-prog' has been removed.
|
||
Use './configure PKG_CONFIG=/full/name/of/pkg-config' if you need to.
|
||
|
||
---
|
||
** The configure option '--with-mmdf' has been removed.
|
||
It was no longer useful, as it relied on libraries that are no longer
|
||
supported, and its presence led to confusion during configuration.
|
||
This affects only the 'movemail' utility; Emacs itself can still
|
||
process MMDF-format files as before.
|
||
|
||
** The configure option '--enable-silent-rules' is now the default,
|
||
and silent rules are now quieter. To get the old behavior where
|
||
'make' chatters a lot, configure with '--disable-silent-rules' or
|
||
build with 'make V=1'.
|
||
|
||
---
|
||
** The configure option '--with-gameuser' now allows to specify a
|
||
group instead of a user if its argument is prefixed by ':' (a colon).
|
||
This will cause the game score files in ${localstatedir}/games/emacs
|
||
to be owned by that group, and the helper program for updating them to
|
||
be installed setgid. The option now defaults to the 'games' group.
|
||
|
||
---
|
||
** The `grep-changelog' script (and its manual page) are no longer included.
|
||
It has no particular connection to Emacs and has not changed in years,
|
||
so if you want to use it, you can always take a copy from an older Emacs.
|
||
|
||
|
||
* Startup Changes in Emacs 25.1
|
||
|
||
|
||
* Changes in Emacs 25.1
|
||
|
||
** New command `comment-line' bound to `C-x C-;'.
|
||
|
||
** New function `custom-prompt-customize-unsaved-options' checks for
|
||
unsaved customizations and prompts user to customize (if found).
|
||
|
||
+++
|
||
** Network security (TLS/SSL certificate validity and the like) is
|
||
added via the new Network Security Manager (NSM) and controlled via
|
||
the `network-security-level' variable.
|
||
|
||
** C-h l now also lists the commands that were run.
|
||
|
||
---
|
||
** The new M-s M-w key binding uses eww to search the web for the
|
||
text in the region.
|
||
|
||
** M-x suggests shorthands and ignores obsolete commands for completion.
|
||
** x-select-enable-clipboard is renamed select-enable-clipboard.
|
||
x-select-enable-primary and renamed select-enable-primary.
|
||
Additionally they both now apply to all systems (OSX, GNUstep, Windows, you
|
||
name it), with the proviso that on some systems (e.g. Windows)
|
||
select-enable-primary is ineffective since the system doesn't
|
||
have the equivalent of a primary selection.
|
||
|
||
+++
|
||
** terpri gets an optional arg ENSURE to conditionally output a newline.
|
||
|
||
+++
|
||
** New macro `define-advice'.
|
||
|
||
** `insert-register' now leaves point after the inserted text
|
||
when called interactively. A prefix argument toggles this behavior.
|
||
|
||
** New var `truncate-string-ellipsis' to choose how to indicate truncation.
|
||
|
||
+++
|
||
** The new variable `term-file-aliases' replaces some files from lisp/term.
|
||
The function `tty-run-terminal-initialization' consults this variable
|
||
when deciding what terminal-specific initialization code to run.
|
||
|
||
---
|
||
** New variable `system-configuration-features', listing some of the
|
||
main features that Emacs was compiled with. This is mainly intended
|
||
for use in Emacs bug reports.
|
||
|
||
+++
|
||
** A password is now hidden also when typed in batch mode. Another
|
||
hiding character but the default `.' can be used by let-binding the
|
||
variable `read-hide-char'.
|
||
|
||
** The new functions `string-collate-lessp' and `string-collate-equalp'
|
||
preserve the collation order as defined by the system's locale(1)
|
||
environment. For the time being this is implemented for modern POSIX
|
||
systems and for MS-Windows, for other systems they fall back to their
|
||
counterparts `string-lessp' and `string-equal'.
|
||
|
||
*** The ls-lisp package uses `string-collate-lessp' to sort file names.
|
||
If you want the old, locale-independent sorting, customize the new
|
||
option `ls-lisp-use-string-collate' to a nil value.
|
||
|
||
*** The MS-Windows specific variable `w32-collate-ignore-punctuation',
|
||
if set to a non-nil value, causes the above 2 functions to ignore
|
||
symbol and punctuation characters when collating strings. This
|
||
emulates the behavior of modern Posix platforms when the locale's
|
||
codeset is "UTF-8" (as in "en_US.UTF-8"). This is needed because
|
||
MS-Windows doesn't support UTF-8 as codeset in its locales.
|
||
|
||
+++
|
||
** The new function `bidi-find-overridden-directionality' allows to
|
||
find characters whose directionality was, perhaps maliciously,
|
||
overridden by directional override control characters. Lisp programs
|
||
can use this to detect potential phishing of URLs and other links that
|
||
exploits bidirectional display reordering.
|
||
|
||
+++
|
||
** The new function `buffer-substring-with-bidi-context' allows to
|
||
copy a portion of a buffer into a different location while preserving
|
||
the visual appearance both of the copied text and the text at
|
||
destination, even when the copied text includes mixed bidirectional
|
||
text and directional control characters.
|
||
|
||
** New variable `ns-use-fullscreen-animation' controls animation for
|
||
non-native NS fullscreen. The default is nil. Set to t to enable
|
||
animation when entering and leaving fullscreen. For native OSX fullscreen
|
||
this has no effect.
|
||
|
||
** A new text property `inhibit-read-only' can be used in read-only
|
||
buffers to allow certain parts of the text to be writable.
|
||
|
||
** A new function `directory-files-recursively' returns all matching
|
||
files (recursively) under a directory.
|
||
|
||
** The new `directory-name-p' can be used to check whether a file
|
||
name (as returned from, for instance, `file-name-all-completions' is
|
||
a directory file name. It returns non-nil if the last character in
|
||
the name is a forward slash.
|
||
|
||
+++
|
||
** New variable `fast-but-imprecise-scrolling' inhibits
|
||
fontification during full screen scrolling operations, giving less
|
||
hesitant operation during auto-repeat of C-v, M-v at the cost of
|
||
possible inaccuracies in the end position.
|
||
|
||
** The function `font-info' now returns more details about a font.
|
||
In particular, it now returns the average width of the font's
|
||
characters, which can be used for geometry-related calculations.
|
||
|
||
** A new function `default-font-width' returns the average width of a
|
||
character in the current buffer's default font. If the default face
|
||
is remapped (see `face-remapping-alist'), the value for the remapped
|
||
face is returned. This function complements the existing function
|
||
`default-font-height'.
|
||
|
||
** New functions `window-font-height' and `window-font-width' return
|
||
the height and average width of characters in a specified face and
|
||
window. If FACE is remapped (see `face-remapping-alist'), the
|
||
function returns the information for the remapped face.
|
||
|
||
** A new function `window-max-chars-per-line' returns the maximal
|
||
number of characters that can be displayed on one line. If a face
|
||
and/or window are provided, these values are used for the
|
||
calculation. This function is different from `window-body-width' in
|
||
that it accounts for (i) continuation glyphs, (ii) the size of the
|
||
font, and (iii) the specified window.
|
||
|
||
** New possible value for `system-type': nacl.
|
||
|
||
+++
|
||
** New variable `inhibit-message', when bound to non-nil, inhibits
|
||
`message' and related functions from displaying messages the Echo
|
||
Area. The output is still logged to the *Messages* buffer.
|
||
|
||
|
||
* Editing Changes in Emacs 25.1
|
||
|
||
** Successive single-char deletions are collapsed in the undo-log just like
|
||
successive char insertions.
|
||
|
||
** Unicode names entered via C-x 8 RET now use substring completion by default.
|
||
|
||
** New minor mode global-eldoc-mode is enabled by default.
|
||
|
||
** Emacs now supports "bracketed paste mode" when running on a terminal
|
||
that supports it. This facility allows Emacs to understand pasted
|
||
chunks of text as strings to be inserted, instead of interpreting each
|
||
character in the pasted text as actual user input. This results in a
|
||
paste experience similar to that under a window system, and significant
|
||
performance improvements when pasting large amounts of text.
|
||
|
||
** Emacs now supports the latest version of the UBA.
|
||
The Emacs implementation of the Unicode Bidirectional Algorithm (UBA)
|
||
was updated to support all the latest additions and changes introduced
|
||
in Unicode Standard versions 6.3 and 7.0, and a few changes suggested
|
||
for Unicode 8.0. This includes full support for directional isolates
|
||
and the Bidirectional Parentheses Algorithm (BPA) specified by these
|
||
Unicode standards.
|
||
|
||
** You can access `mouse-buffer-menu' (C-down-mouse-1) using C-f10.
|
||
|
||
+++
|
||
** New buffer-local `electric-pair-local-mode'.
|
||
|
||
|
||
* Changes in Specialized Modes and Packages in Emacs 25.1
|
||
|
||
** The `save-place' variable is replaced by a `save-place-mode'.
|
||
|
||
** Midnight-mode
|
||
*** `midnight-mode' is a proper minor mode.
|
||
*** clean-buffer-*-regexps can now specify buffers via predicate functions.
|
||
|
||
** In xterms, killing text now also sets the CLIPBOARD/PRIMARY selection
|
||
in the surrounding GUI (using the OSC-52 escape sequence). This only works
|
||
if your xterm supports it and enables the `allowWindowOps' options (disabled
|
||
by default at least in Debian, for security reasons).
|
||
|
||
** xterm-mouse-mode now supports mouse-tracking (if your xterm supports it).
|
||
|
||
** package.el
|
||
|
||
*** If a package is available on multiple archives and one has higher
|
||
priority (as per `package-archive-priorities') only that one is
|
||
listed. This can be configured with `package-menu-hide-low-priority'.
|
||
|
||
*** `package-menu-hide-obsolete' now toggles the hiding of packages.
|
||
This includes the above-mentioned low-priority packages, as well as
|
||
available packages whose version is lower than the currently installed
|
||
version (which were previously impossible to display).
|
||
This allows users to downgrade a package if a lower version is
|
||
available.
|
||
|
||
*** When filtering the package menu, keywords starting with "arc:" or
|
||
"status:" represent package archive or status, respectively, instead
|
||
of actual keywords.
|
||
|
||
*** Most functions which involve downloading information now take an
|
||
ASYNC argument. If it is non-nil, package.el performs the download(s)
|
||
asynchronously.
|
||
|
||
*** New variable `package-menu-async' controls whether the
|
||
package-menu uses asynchronous downloads.
|
||
|
||
*** `package-install-from-buffer' and `package-install-file' work on directories.
|
||
This follows the same rules as installing from a .tar file, except the
|
||
-pkg file is optional.
|
||
|
||
*** Packages which are dependencies of other packages cannot be deleted.
|
||
The FORCE argument to `package-delete' overrides this.
|
||
|
||
*** New custom variable `package-selected-packages' tracks packages
|
||
which were installed by the user (as opposed to installed as
|
||
dependencies). This variable can also be manually customized.
|
||
|
||
*** New command `package-install-user-selected-packages' installs all
|
||
packages from `package-selected-packages' which are currently missing.
|
||
|
||
*** New command `package-autoremove' removes all packages which were
|
||
installed strictly as dependencies but are no longer needed.
|
||
|
||
** Shell
|
||
|
||
When you invoke `shell' interactively, the *shell* buffer will now
|
||
display in a new window. However, you can customize this behavior via
|
||
the `display-buffer-alist' variable. For example, to get
|
||
the old behavior -- *shell* buffer displays in current window -- use
|
||
(add-to-list 'display-buffer-alist
|
||
'("^\\*shell\\*$" . (display-buffer-same-window))).
|
||
|
||
|
||
** EIEIO
|
||
+++
|
||
*** The `:protection' slot option is not obeyed any more.
|
||
+++
|
||
*** The `newname' argument to constructors is optional&deprecated.
|
||
If you need your objects to be named, do it by inheriting from `eieio-named'.
|
||
+++
|
||
*** The <class>-list-p and <class>-child-p functions are declared obsolete.
|
||
+++
|
||
*** The <class> variables are declared obsolete.
|
||
+++
|
||
*** The <initarg> variables are declared obsolete.
|
||
*** defgeneric and defmethod are declared obsolete.
|
||
+++
|
||
*** `constructor' is now an obsolete alias for `make-instance'.
|
||
|
||
** ido
|
||
*** New command `ido-bury-buffer-at-head' bound to C-S-b
|
||
Bury the buffer at the head of `ido-matches', analogous to how C-k
|
||
kills the buffer at head.
|
||
|
||
** Minibuffer
|
||
|
||
*** You can use <up> and <down> keys to move point in the multi-line
|
||
minibuffer just as in an ordinary buffer. Only when point moves over
|
||
the bottom/top of the minibuffer it goes to the next/previous history
|
||
element. The new commands bound to <up> and <down> in the minibuffer:
|
||
`next-line-or-history-element' and `previous-line-or-history-element'.
|
||
|
||
** Search and Replace
|
||
|
||
*** Query-replace history is enhanced.
|
||
When query-replace reads the FROM string from the minibuffer, typing
|
||
`M-p' will now show previous replacements as "FROM SEP TO", where FROM
|
||
and TO are the original text and its replacement, and SEP is an arrow
|
||
string defined by the new variable `query-replace-from-to-separator'.
|
||
To select a prior replacement, type `M-p' until the desired
|
||
replacement appears in the minibuffer, and then exit the minibuffer by
|
||
typing RET.
|
||
|
||
** Calc
|
||
+++
|
||
*** If `quick-calc' is called with a prefix argument, insert the
|
||
result of the calculation into the current buffer.
|
||
|
||
** ElDoc
|
||
*** New minor mode `global-eldoc-mode'
|
||
*** `eldoc-documentation-function' now defaults to `ignore'
|
||
*** `describe-char-eldoc' displays information about character at point,
|
||
and can be used as a default value of `eldoc-documentation-function'. It is
|
||
useful when, for example, one needs to distinguish various spaces (e.g. ] [,
|
||
] [, ] [, etc.) while using mono-spaced font.
|
||
|
||
** eww
|
||
|
||
---
|
||
*** HTML can now be rendered using variable-width fonts.
|
||
|
||
+++
|
||
*** A new command `F' (`eww-toggle-fonts') can be used to toggle
|
||
whether to use variable-pitch fonts or not. The user can also
|
||
customize the `shr-use-fonts' variable.
|
||
|
||
+++
|
||
*** A new command `R' (`eww-readable') will try do identify the main
|
||
textual parts of a web page and display only that, leaving menus and
|
||
the like off the page.
|
||
|
||
---
|
||
*** You can now use several eww buffers in parallel by renaming eww
|
||
buffers you want to keep separate.
|
||
|
||
+++
|
||
*** Partial state of the eww buffers (the URIs and the titles of the
|
||
pages visited) is now preserved in the desktop file.
|
||
|
||
+++
|
||
*** `eww-after-render-hook' is now called after eww has rendered
|
||
the data in the buffer.
|
||
|
||
---
|
||
*** The `eww-reload' command now takes a prefix to not reload via
|
||
the net, but just use the local copy of the HTML.
|
||
|
||
+++
|
||
*** The DOM shr and eww uses has been changed to the general Emacs
|
||
xml.el/libxml2 DOM, and a new package dom.el has been added to
|
||
interact with this DOM. See the Emacs Lisp manual for interface
|
||
details.
|
||
|
||
+++
|
||
*** `mailcap-mime-data' is now consulted when displaying PDF files.
|
||
|
||
+++
|
||
*** The new `S' command will list all eww buffers, and allow managing
|
||
them.
|
||
|
||
---
|
||
*** https pages with valid certificates have headers marked in green, while
|
||
invalid certificates are marked in red.
|
||
|
||
** Message mode
|
||
|
||
*** text/html messages that contain inline image parts will be
|
||
transformed into multipart/related messages before sending.
|
||
|
||
** pcase
|
||
*** New UPatterns `quote', `app', `cl-struct', and `eieio'.
|
||
*** New UPatterns can be defined with `pcase-defmacro'.
|
||
+++
|
||
*** New vector QPattern.
|
||
|
||
** Lisp mode
|
||
*** Strings after `:documentation' are highlighted as docstrings.
|
||
|
||
** Rectangle editing
|
||
*** Rectangle Mark mode can have corners past EOL or in the middle of a TAB.
|
||
*** C-x C-x in rectangle-mark-mode now cycles through the four corners.
|
||
*** `string-rectangle' provides on-the-fly preview of the result.
|
||
|
||
** New font-lock functions font-lock-ensure and font-lock-flush, which
|
||
should be used instead of font-lock-fontify-buffer when called from Elisp.
|
||
|
||
** Macro `minibuffer-with-setup-hook' takes (:append FUN) to mean
|
||
appending FUN to `minibuffer-setup-hook'.
|
||
|
||
** cl-lib
|
||
*** New functions cl-fresh-line, cl-digit-char-p and cl-parse-integer.
|
||
|
||
** seq
|
||
*** New seq library:
|
||
The seq library adds sequence manipulation functions and macros that
|
||
complement basic functions provided by subr.el. All functions are
|
||
prefixed with `seq-' and work on lists, strings and vectors.
|
||
|
||
** Calendar and diary
|
||
|
||
+++
|
||
*** New commands to insert diary entries with Chinese dates:
|
||
`diary-chinese-insert-anniversary-entry' `diary-chinese-insert-entry'
|
||
`diary-chinese-insert-monthly-entry', `diary-chinese-insert-yearly-entry'.
|
||
|
||
+++
|
||
*** The calendar can now list and mark diary entries with Chinese dates.
|
||
See `diary-chinese-list-entries' and `diary-chinese-mark-entries'.
|
||
|
||
---
|
||
*** The option `calendar-mode-line-format' can now be nil,
|
||
which means to do nothing special with the mode line in calendars.
|
||
|
||
---
|
||
*** Many items obsolete since at least version 23.1 have been removed.
|
||
The majority were function/variable/face aliases, too numerous to list here.
|
||
The remainder were:
|
||
|
||
**** Functions `calendar-one-frame-setup', `calendar-only-one-frame-setup',
|
||
`calendar-two-frame-setup', `european-calendar', `american-calendar'.
|
||
|
||
**** Hooks `cal-menu-load-hook', `cal-x-load-hook'.
|
||
|
||
**** Macro `calendar-for-loop'.
|
||
|
||
**** Variables `european-calendar-style', `diary-face', `hebrew-holidays-{1,4}'.
|
||
|
||
**** The nil and list forms of `diary-display-function'.
|
||
|
||
** New ERT function `ert-summarize-tests-batch-and-exit'.
|
||
|
||
** New js.el option `js-indent-first-init'.
|
||
|
||
---
|
||
** `Info-fontify-maximum-menu-size' can be t for no limit.
|
||
|
||
+++
|
||
** `info-display-manual' can now be given a prefix argument which (any
|
||
non-nil value) directs the command to limit the completion
|
||
alternatives to currently visited manuals.
|
||
|
||
---
|
||
** ntlm.el has support for NTLM2.
|
||
|
||
---
|
||
** The Rmail commands d, C-d and u now handle repeat counts to delete or
|
||
undelete multiple messages.
|
||
|
||
** Rmail can now render HTML mail messages if your Emacs was built with
|
||
libxml2 or if you have the Lynx browser installed. By default, Rmail
|
||
will display the HTML version of a mail message that has both HTML and
|
||
plain text parts, if display of HTML email is possible; customize the
|
||
`rmail-mime-prefer-html' option to `nil' if you don't want that.
|
||
|
||
** SES now supports local printer functions; see `ses-define-local-printer'.
|
||
|
||
** In sh-mode, you can now use `sh-shell' as a file-local variable to
|
||
specify the type of shell in use (bash, csh, etc).
|
||
|
||
** TLS
|
||
---
|
||
*** Fatal TLS errors are now silent by default.
|
||
|
||
** URL
|
||
|
||
*** The URL package accepts now the protocols "ssh", "scp" and "rsync".
|
||
When `url-handler-mode' is enabled, file operations for these
|
||
protocols as well as for "telnet" and "ftp" are passed to Tramp.
|
||
|
||
*** The URL package allows customizing the `url-user-agent' string.
|
||
The new `url-user-agent' variable can be customized to be a string or
|
||
a function.
|
||
|
||
*** The new interface variable `url-request-noninteractive' can be used
|
||
to specify that we're running in a noninteractive context, and that
|
||
we should not be queried about things like TLS certificate validity.
|
||
|
||
*** If URL is used with a https connection, the first callback argument
|
||
plist will contain a :peer element that has the output of
|
||
`gnutls-peer-status' (if Emacs is built with GnuTLS support).
|
||
|
||
** Tramp
|
||
|
||
*** New connection method "nc", which allows to access dumb busyboxes.
|
||
|
||
** SQL mode
|
||
|
||
*** New user variable `sql-default-directory' enables remote
|
||
connections using Tramp.
|
||
|
||
*** New command `sql-send-line-and-next' sends the current line to the
|
||
interactive buffer and advances to the next line, skipping whitespace
|
||
and comments.
|
||
|
||
*** Add support for Vertica SQL.
|
||
|
||
** VC and related modes
|
||
|
||
*** The new command vc-region-history shows the log+diff of the active region.
|
||
|
||
*** New option `vc-annotate-background-mode' controls whether
|
||
the color range from `vc-annotate-color-map' is applied to the
|
||
background or to the foreground.
|
||
|
||
*** `compare-windows' now compares text with the most recently used window
|
||
instead of the next window. The new option `compare-windows-get-window-function'
|
||
allows to customize this.
|
||
|
||
*** Two new faces `compare-windows-removed' and `compare-windows-added'
|
||
replace the obsolete face `compare-windows'.
|
||
|
||
** VHDL mode supports VHDL'08.
|
||
|
||
** Calculator: decimal display mode uses "," groups, so it's more
|
||
fitting for use in money calculations; factorial works with
|
||
non-integer inputs.
|
||
|
||
** HideIfDef mode now support full C/C++ expressions, argumented macro expansions
|
||
, interactive macro evaluation and automatic scanning of #defined symbols.
|
||
|
||
*** New custom variable `hide-ifdef-header-regexp' to define C/C++ header file
|
||
name patterns. Default case-insensitive .h, .hh, .hpp and .hxx.
|
||
*** New custom variable `hide-ifdef-expand-reinclusion-protection' to prevent
|
||
reinclusion protected header files from being fully hidden.
|
||
*** New custom variable `hide-ifdef-exclude-define-regexp' to define symbol
|
||
name patterns (e.x. all "FOR_DOXYGEN_ONLY_*") to be excluded.
|
||
|
||
** TeX mode
|
||
|
||
*** New custom variable `tex-print-file-extension' to help users who
|
||
use PDF instead of DVI.
|
||
|
||
** whitespace-mode: new 'big-indent style highlighting too much indentation.
|
||
By default, 32 spaces and four TABs are considered to be too much but
|
||
`whitespace-big-indent-regexp' can be configured to change that.
|
||
|
||
** tildify: `tildify-space-string', `tildify-pattern', and
|
||
`tildify-foreach-region-function' variables added making
|
||
`tildify-string-alist', `tildify-pattern-alist', and
|
||
`tildify-ignored-environments-alist' variables (as well as a few
|
||
helper functions) obsolete.
|
||
|
||
** xref
|
||
The new package provides generic framework and new commands to find
|
||
and move to definitions, as well as pop back to the original location.
|
||
|
||
*** New key bindings
|
||
`xref-find-definitions' replaces `find-tag' and provides an interface
|
||
to pick one destination among several. Hence, `tags-loop-continue' is
|
||
unbound. `xref-pop-marker-stack' replaces `pop-tag-mark', but uses an
|
||
easier binding, which is now unoccupied (`M-,').
|
||
`xref-find-definitions-other-window' replaces `find-tag-other-window'.
|
||
`xref-find-definitions-other-frame' replaces `find-tag-other-frame'.
|
||
`xref-find-apropos' replaces `find-tag-regexp'.
|
||
|
||
*** New variables
|
||
`find-tag-marker-ring-length' is now an obsolete alias for
|
||
`xref-marker-ring-length'. `find-tag-marker-ring' is now an obsolete
|
||
alias for a private variable. `xref-push-marker-stack' and
|
||
`xref-pop-marker-stack' should be used to mutate it instead.
|
||
|
||
** etags
|
||
As a result of the above, these commands are now obsolete:
|
||
`find-tag-other-window', `find-tag-other-frame', `find-tag-regexp',
|
||
`tags-apropos' and `tags-loop-continue'.
|
||
|
||
** EUDC
|
||
EUDC's LDAP backend has been improved.
|
||
|
||
*** EUDC supports LDAP-over-SSL URLs (ldaps://).
|
||
|
||
*** EUDC passes LDAP passwords through a pipe to the ldapsearch
|
||
subprocess instead of on the command line.
|
||
|
||
*** EUDC handles LDAP wildcards automatically so the user shouldn't
|
||
need to configure this manually anymore.
|
||
|
||
*** The LDAP configuration section of EUDC's manual has been
|
||
rewritten.
|
||
|
||
There have also been customization changes.
|
||
|
||
*** New custom variable `eudc-server-hotlist' to allow specifying
|
||
multiple EUDC servers in init file.
|
||
|
||
*** Custom variable `eudc-inline-query-format' defaults to completing
|
||
on email and firstname instead of surname.
|
||
|
||
*** Custom variable `eudc-expansion-overwrites-query' defaults to nil
|
||
to avoid interfering with the kill ring.
|
||
|
||
*** Custom variable `eudc-inline-expansion-format' defaults to
|
||
"Firstname Surname <mail-address>".
|
||
|
||
*** Custom variable `eudc-options-file' defaults to
|
||
"~/.emacs.d/eudc-options".
|
||
|
||
*** New custom variable `ldap-ldapsearch-password-prompt-regexp' to
|
||
allow overriding the regular expression that recognizes the ldapsearch
|
||
command line's password prompt.
|
||
|
||
** Eshell
|
||
|
||
+++
|
||
*** The new built-in command `clear' can scroll window contents out of sight.
|
||
If provided with an optional non-nil argument, the scrollback contents will be cleared.
|
||
|
||
** Browse-url
|
||
|
||
*** Support for the Conkeror web browser.
|
||
|
||
---
|
||
*** Support for several ancient browsers is now officially obsolete.
|
||
|
||
+++
|
||
** tar-mode: new `tar-new-entry' command, allowing for new members to
|
||
be added to the archive.
|
||
|
||
** Autorevert: dired buffers are also auto-reverted via file
|
||
notifications, if Emacs is compiled with file notification support.
|
||
|
||
** Obsolete packages
|
||
|
||
---
|
||
*** gulp.el
|
||
|
||
+++
|
||
** The character classes [:graph:] and [:print:] in regular expressions
|
||
no longer match every multibyte character. Instead, Emacs now
|
||
consults the Unicode character properties to determine which
|
||
characters are graphic or printable. In particular, surrogates and
|
||
unassigned codepoints are now rejected. If you want the old behavior,
|
||
use [:multibyte:] instead.
|
||
|
||
|
||
* New Modes and Packages in Emacs 25.1
|
||
|
||
** cl-generic.el provides CLOS-style multiple-dispatch generic functions.
|
||
|
||
** scss-mode (a minor variant of css-mode)
|
||
|
||
** let-alist is a new macro (and a package) that allows one to easily
|
||
let-bind the values stored in an alist.
|
||
|
||
** `tildify-mode' allows to automatically insert hard spaces as one
|
||
types the text. Breaking line after a single-character words is
|
||
forbidden by Czech and Polish typography (and may be discouraged in
|
||
other languages), so `auto-tildify-mode' makes it easier to create
|
||
a typographically-correct documents.
|
||
|
||
* Incompatible Lisp Changes in Emacs 25.1
|
||
|
||
** Comint, term, and compile do not set the EMACS env var any more.
|
||
Use the INSIDE_EMACS environment variable instead.
|
||
|
||
** `save-excursion' does not save&restore the mark any more.
|
||
|
||
** read-buffer-function can now be called with a 4th argument (`predicate').
|
||
|
||
** completion-table-dynamic stays in the minibuffer.
|
||
If you want the old behavior of calling the function in the buffer
|
||
from which the minibuffer was entered, call it with the new argument
|
||
`switch-buffer'.
|
||
|
||
** window-configurations no longer record the buffers's marks.
|
||
|
||
** inhibit-modification-hooks now also inhibits lock-file checks, as well as
|
||
active region handling.
|
||
|
||
** deactivate-mark is now buffer-local.
|
||
|
||
** `cl-the' now asserts that its argument is of the given type.
|
||
|
||
** `process-running-child-p` may now return a numeric process
|
||
group ID instead of `t'.
|
||
|
||
+++
|
||
** Mouse click events on mode line or header line no longer include
|
||
any reference to a buffer position. The 6th member of the mouse
|
||
position list returned for such events is now nil.
|
||
|
||
** Menu items in keymaps do not support the "key shortcut cache" any more.
|
||
These slots used to hold key-shortcut data, but have been obsolete since
|
||
Emacs-21.
|
||
|
||
** Emacs no longer downcases the first letter of a system diagnostic
|
||
when signaling a file error. For example, it now reports "Permission
|
||
denied" instead of "permission denied". The old behavior was problematic
|
||
in languages like German where downcasing rules depend on grammar.
|
||
|
||
+++
|
||
** The character classes [:alpha:] and [:alnum:] in regular expressions
|
||
now match multibyte characters using Unicode character properties.
|
||
If you want the old behavior where they matched any character with
|
||
word syntax, use `\sw' instead.
|
||
|
||
+++
|
||
** The `diff' command uses the unified format now. To restore the old
|
||
behavior, set `diff-switches' to `-c'.
|
||
|
||
|
||
* Lisp Changes in Emacs 25.1
|
||
|
||
** New hook `pre-redisplay-functions', a bit easier to use than pre-redisplay-function.
|
||
|
||
** The second arg of `looking-back' should always be provided explicitly.
|
||
|
||
** Obsolete text properties `intangible', `point-entered', and `point-left'.
|
||
Replaced by properties `cursor-intangible' and `cursor-sensor-functions',
|
||
implemented by the new `cursor-intangible-mode' and
|
||
`cursor-sensor-mode' minor modes.
|
||
|
||
** New process type `pipe', which can be used in combination with the
|
||
`:stderr' keyword of make-process to handle standard error output
|
||
of subprocess.
|
||
|
||
** New function `make-process' provides an alternative interface to
|
||
`start-process'. It allows programs to set process parameters such as
|
||
process filter, sentinel, etc., through keyword arguments (similar to
|
||
`make-network-process').
|
||
|
||
** `read-buffer' takes a new `predicate' argument.
|
||
|
||
** Emacs Lisp now supports generators.
|
||
|
||
** New finalizer facility for running code when objects
|
||
become unreachable.
|
||
|
||
** lexical closures can use (:documentation <form>) to build their docstring.
|
||
It should be placed right where the docstring would be, and <form> is then
|
||
evaluated (and should return a string) when the closure is built.
|
||
|
||
** define-inline provides a new way to define inlinable functions.
|
||
|
||
** New function macroexpand-1 to perform a single step of macroexpansion.
|
||
|
||
** Some "x-*" were obsoleted:
|
||
*** x-select-text is renamed gui-select-text.
|
||
*** x-selection-value is renamed gui-selection-value.
|
||
*** x-get-selection is renamed gui-get-selection.
|
||
*** x-get-clipboard and x-clipboard-yank are marked obsolete.
|
||
*** x-get-selection-value is renamed to gui-get-primary-selection.
|
||
*** x-set-selection is renamed to gui-set-selection
|
||
|
||
** New function `alist-get', which is also a valid place (aka lvalue).
|
||
|
||
** New function `funcall-interactively', which works like `funcall'
|
||
but makes `called-interactively-p' treat the function as (you guessed it)
|
||
called interactively.
|
||
|
||
** New function `function-put' to use instead of `put' for function properties.
|
||
|
||
+++
|
||
** New properties that can be specified with `declare':
|
||
*** (interactive-only INSTEAD), says to use INSTEAD for non-interactive use.
|
||
*** (pure VAL), if VAL is non-nil, indicates the function is pure.
|
||
*** (side-effect-free VAL), if VAL is non-nil, indicates the function does not
|
||
have side effects.
|
||
|
||
+++
|
||
** New macro `with-file-modes', for evaluating expressions with default file
|
||
permissions set to temporary values (e.g., for creating private files).
|
||
|
||
** You can access the slots of structures using `cl-struct-slot-value'.
|
||
|
||
** Functions `rmail-delete-forward' and `rmail-delete-backward' take an
|
||
optional repeat-count argument.
|
||
|
||
** Function `sort' can deal with vectors.
|
||
|
||
** Function `system-name' now returns an updated value if the current
|
||
system's name has changed or if the Emacs process has changed systems,
|
||
and to avoid long waits it no longer consults DNS to canonicalize the
|
||
name. The variable `system-name' is now obsolete.
|
||
|
||
+++
|
||
** Function `write-region' no longer outputs "Wrote FILE" in batch mode.
|
||
|
||
---
|
||
** New utilities in subr-x.el:
|
||
*** New macros `if-let' and `when-let' allow defining bindings and to
|
||
execute code depending whether all values are true.
|
||
*** New macros `thread-first' and `thread-last' allow threading a form
|
||
as the first or last argument of subsequent forms.
|
||
|
||
+++
|
||
** Time-related changes:
|
||
|
||
*** Time-related functions now consistently accept numbers
|
||
(representing seconds since the epoch) and nil (representing the
|
||
current time) as well as the usual list-of-integer representation.
|
||
Affected functions include `current-time-string', `current-time-zone',
|
||
`decode-time', `float-time', `format-time-string', `seconds-to-time',
|
||
`time-add', `time-less-p', `time-subtract', `time-to-day-in-year',
|
||
`time-to-days', and `time-to-seconds'.
|
||
|
||
*** The `encode-time-value' and `with-decoded-time-value' macros have
|
||
been obsoleted.
|
||
|
||
*** `calendar-next-time-zone-transition', `time-add', and
|
||
`time-subtract' no longer return time values in the obsolete and
|
||
undocumented integer-pair format. Instead, they return a list of two
|
||
integers.
|
||
|
||
+++
|
||
** New function `set-binary-mode' allows to switch a standard stream
|
||
of the Emacs process to binary I/O mode.
|
||
|
||
** Miscellaneous name change
|
||
|
||
For consistency with the usual Emacs spelling, the Lisp variable
|
||
`hfy-optimisations' has been renamed to `hfy-optimizations'.
|
||
The old name should still work, as an obsolescent alias.
|
||
|
||
|
||
* Changes in Frames and Windows Code in Emacs 25.1
|
||
|
||
+++
|
||
** Emacs can now draw horizontal scroll bars on some platforms that
|
||
provide toolkit scroll bars, namely Gtk+, Lucid, Motif and Windows.
|
||
Horizontal scroll bars are turned off by default.
|
||
*** New function `horizontal-scroll-bars-available-p' telling whether
|
||
horizontal scroll bars are available on the underlying system.
|
||
*** New mode `horizontal-scroll-bar-mode' to toggle horizontal scroll
|
||
bars on all existing and future frames.
|
||
*** New function `toggle-horizontal-scroll-bar' to toggle horizontal
|
||
scroll bars on the selected frame.
|
||
*** New frame parameters `horizontal-scroll-bars' and
|
||
`scroll-bar-height' to set horizontal scroll bars and their height
|
||
for individual frames and in `default-frame-alist'.
|
||
*** New functions `frame-scroll-bar-height' and
|
||
`window-scroll-bar-height' return the height of horizontal scroll
|
||
bars on a specific frame or window.
|
||
*** `set-window-scroll-bars' now accepts five parameters where the last
|
||
two specify height and type of the window's horizontal scroll bar.
|
||
*** `window-scroll-bars' now returns type and sizes of horizontal scroll
|
||
bars too.
|
||
*** New buffer-local variables `horizontal-scroll-bar' and
|
||
`scroll-bar-height'.
|
||
|
||
+++
|
||
** The height of a frame's menu and tool bar are no longer counted in the
|
||
frame's text height. This means that the text height stands only for
|
||
the height of the frame's root window plus that of the echo area (if
|
||
present). This was already the behavior for frames with external tool
|
||
and menu bars (like in the Gtk builds) but has now been extended to all
|
||
builds.
|
||
|
||
+++
|
||
** Frames now do not necessarily preserve the number of columns or lines
|
||
they display when setting default font, menu bar, fringe width, or
|
||
scroll bars. In particular, maximized and fullscreen frames are
|
||
conceptually never resized if such settings change. For fullheight and
|
||
fullwidth frames, the behavior may depend on the toolkit used.
|
||
*** New option `frame-inhibit-implied-resize' if non-nil, means that
|
||
setting default font, menu bar, fringe width, or scroll bars of a
|
||
specific frame does not resize that frame in order to preserve the
|
||
number of columns or lines it displays.
|
||
|
||
+++
|
||
** New function `window-preserve-size' allows to preserve the size of
|
||
windows without "fixing" it. It's supported by `fit-window-to-buffer',
|
||
`temp-buffer-resize-mode' and `display-buffer'.
|
||
|
||
** Tearoff menus and detachable toolbars for Gtk+ has been removed.
|
||
Those features have been deprecated in Gtk+ for a long time.
|
||
|
||
|
||
* Changes in Emacs 25.1 on Non-Free Operating Systems
|
||
|
||
---
|
||
** Building Emacs for MS-Windows requires at least Windows XP
|
||
or Windows Server 2003. The built binaries still run on all versions
|
||
of Windows starting with Windows 9X.
|
||
|
||
+++
|
||
** Emacs running on MS-Windows now supports the daemon mode.
|
||
|
||
** OS X 10.5 or older is no longer supported.
|
||
|
||
** OS X on PowerPC is no longer supported.
