-* Changes for non-free operating systems
+* Changes in Emacs 22.1 on non-free operating systems
+++
** Passing resources on the command line now works on MS Windows.
+
You can use --xrm to pass resource settings to Emacs, overriding any
existing values. For example:
---
** On MS Windows, the "system caret" now follows the cursor.
+
This enables Emacs to work better with programs that need to track
the cursor, for example screen magnifiers and text to speech programs.
---
** Tooltips now work on MS Windows.
+
See the Emacs 21.1 NEWS entry for tooltips for details.
---
** Images are now supported on MS Windows.
+
PBM and XBM images are supported out of the box. Other image formats
depend on external libraries. All of these libraries have been ported
to Windows, and can be found in both source and binary form at
---
** Sound is now supported on MS Windows.

WAV format is supported on all versions of Windows, other formats such
as AU, AIFF and MP3 may be supported in the more recent versions of
Windows, or when other software provides hooks into the system level
---
** Different shaped mouse pointers are supported on MS Windows.
+
The mouse pointer changes shape depending on what is under the pointer.
---
** Pointing devices with more than 3 buttons are now supported on MS Windows.
+
The new variable `w32-pass-extra-mouse-buttons-to-system' controls
whether Emacs should handle the extra buttons itself (the default), or
pass them to Windows to be handled with system-wide functions.
---
** Emacs takes note of colors defined in Control Panel on MS-Windows.

\f
* Lisp Changes in Emacs 22.1
-** New function `locate-file' searches for a file in a list of directories.
-`locate-file' accepts a name of a file to search (a string), and two
-lists: a list of directories to search in and a list of suffixes to
-try; typical usage might use `exec-path' and `load-path' for the list
-of directories, and `exec-suffixes' and `load-suffixes' for the list
-of suffixes. The function also accepts a predicate argument to
-further filter candidate files.
-
-One advantage of using this function is that the list of suffixes in
-`exec-suffixes' is OS-dependant, so this function will find
-executables without polluting Lisp code with OS dependancies.
+** General Lisp changes:
+++
-** The default value of `sentence-end' is now defined using the new
-variable `sentence-end-without-space', which contains such characters
-that end a sentence without following spaces.
-
-The function `sentence-end' should be used to obtain the value of the
-variable `sentence-end'. If the variable `sentence-end' is nil, then
-this function returns the regexp constructed from the variables
-`sentence-end-without-period', `sentence-end-double-space' and
-`sentence-end-without-space'.
+*** The function `eql' is now available without requiring the CL package.
+++
-** The argument to forward-word, backward-word, forward-to-indentation
-and backward-to-indentation is now optional, and defaults to 1.
+*** `makehash' is now obsolete. Use `make-hash-table' instead.
+++
-** If a command sets transient-mark-mode to `only', that
-enables Transient Mark mode for the following command only.
-During that following command, the value of transient-mark-mode
-is `identity'. If it is still `identity' at the end of the command,
-it changes to nil.
+*** `add-to-list' takes an optional third argument, APPEND.
+
+If APPEND is non-nil, the new element gets added at the end of the
+list instead of at the beginning. This change actually occurred in
+Emacs 21.1, but was not documented then.
+++
-** The new hook `before-save-hook' is invoked by `basic-save-buffer'
-before saving buffers. This allows packages to perform various final
-tasks, for example; it can be used by the copyright package to make
-sure saved files have the current year in any copyright headers.
+*** New function `add-to-ordered-list' is like `add-to-list' but
+associates a numeric ordering of each element added to the list.
+++
-** If a buffer sets buffer-save-without-query to non-nil,
-save-some-buffers will always save that buffer without asking
-(if it's modified).
+*** New function `copy-tree' makes a copy of a tree.
----
-** list-buffers-noselect now takes an additional argument, BUFFER-LIST.
-If it is non-nil, it specifies which buffers to list.
+It recursively copyies through both CARs and CDRs.
+++
-** The kill-buffer-hook is now permanent-local.
+*** New function `delete-dups' deletes `equal' duplicate elements from a list.
-+++
-** `auto-save-file-format' has been renamed to
-`buffer-auto-save-file-format' and made into a permanent local.
+It modifies the list destructively, like `delete'. Of several `equal'
+occurrences of an element in the list, the one that's kept is the
+first one.
+++
-** Functions `file-name-sans-extension' and `file-name-extension' now
-ignore the leading dots in file names, so that file names such as
-`.emacs' are treated as extensionless.
+*** New function `rassq-delete-all'.
+
+(rassq-delete-all VALUE ALIST) deletes, from ALIST, each element whose
+CDR is `eq' to the specified value.
+++
-** copy-file now takes an additional option arg MUSTBENEW.
+*** The function `number-sequence' makes a list of equally-separated numbers.
-This argument works like the MUSTBENEW argument of write-file.
+For instance, (number-sequence 4 9) returns (4 5 6 7 8 9). By
+default, the separation is 1, but you can specify a different
+separation as the third argument. (number-sequence 1.5 6 2) returns
+(1.5 3.5 5.5).
+++
-** If the second argument to `copy-file' is the name of a directory,
-the file is copied to that directory instead of signaling an error.
+*** New variables `most-positive-fixnum' and `most-negative-fixnum'.
-+++
-** `visited-file-modtime' and `calendar-time-from-absolute' now return
-a list of two integers, instead of a cons.
+They hold the largest and smallest possible integer values.
+++
-** `file-chase-links' now takes an optional second argument LIMIT which
-specifies the maximum number of links to chase through. If after that
-many iterations the file name obtained is still a symbolic link,
-`file-chase-links' returns it anyway.
+*** Minor change in the function `format'.
-+++
-** The function `commandp' takes an additional optional
-argument. If it is non-nil, then `commandp' checks
-for a function that could be called with `call-interactively',
-and does not return t for keyboard macros.
+Some flags that were accepted but not implemented (such as "*") are no
+longer accepted.
+++
-** An interactive specification can now use the code letter 'U' to get
-the up-event that was discarded in case the last key sequence read for a
-previous 'k' or 'K' argument was a down-event; otherwise nil is used.
+*** Functions `get' and `plist-get' no longer give errors for bad plists.
----
-** Functions y-or-n-p, read-char, read-key-sequence and the like, that
-display a prompt but don't use the minibuffer, now display the prompt
-using the text properties (esp. the face) of the prompt string.
+They return nil for a malformed property list or if the list is
+cyclic.
+++
-** read-from-minibuffer now accepts an additional argument KEEP-ALL
-saying to put all inputs in the history list, even empty ones.
+*** New functions `lax-plist-get' and `lax-plist-put'.
+
+They are like `plist-get' and `plist-put', except that they compare
+the property name using `equal' rather than `eq'.
+++
-** The `read-file-name' function now takes an additional argument which
-specifies a predicate which the file name read must satify. The
-new variable `read-file-name-predicate' contains the predicate argument
-while reading the file name from the minibuffer; the predicate in this
-variable is used by read-file-name-internal to filter the completion list.
+*** New variable `print-continuous-numbering'.
----
-** The new variable `read-file-name-function' can be used by lisp code
-to override the internal read-file-name function.
+When this is non-nil, successive calls to print functions use a single
+numbering scheme for circular structure references. This is only
+relevant when `print-circle' is non-nil.
-+++
-** The new variable `read-file-name-completion-ignore-case' specifies
-whether completion ignores case when reading a file name with the
-`read-file-name' function.
+When you bind `print-continuous-numbering' to t, you should
+also bind `print-number-table' to nil.
+++
-** The new function `read-directory-name' can be used instead of
-`read-file-name' to read a directory name; when used, completion
-will only show directories.
+*** New function `macroexpand-all' expands all macros in a form.
+
+It is similar to the Common-Lisp function of the same name.
+One difference is that it guarantees to return the original argument
+if no expansion is done, which can be tested using `eq'.
+++
-** The new variable search-spaces-regexp controls how to search
-for spaces in a regular expression. If it is non-nil, it should be a
-regular expression, and any series of spaces stands for that regular
-expression. If it is nil, spaces stand for themselves.
+*** The function `atan' now accepts an optional second argument.
-Spaces inside of constructs such as [..] and *, +, ? are never
-replaced with search-spaces-regexp.
+When called with 2 arguments, as in `(atan Y X)', `atan' returns the
+angle in radians between the vector [X, Y] and the X axis. (This is
+equivalent to the standard C library function `atan2'.)
+++
-** There are now two new regular expression operators, \_< and \_>,
-for matching the beginning and end of a symbol. A symbol is a
-non-empty sequence of either word or symbol constituent characters, as
-specified by the syntax table.
+*** A function or macro's doc string can now specify the calling pattern.
+
+You put this info in the doc string's last line. It should be
+formatted so as to match the regexp "\n\n(fn .*)\\'". If you don't
+specify this explicitly, Emacs determines it from the actual argument
+names. Usually that default is right, but not always.
+++
-** skip-chars-forward and skip-chars-backward now handle
-character classes such as [:alpha:], along with individual characters
-and ranges.
+*** New macro `with-local-quit' temporarily allows quitting.
----
-** In `replace-match', the replacement text no longer inherits
-properties from surrounding text.
+A quit inside the body of `with-local-quit' is caught by the
+`with-local-quit' form itself, but another quit will happen later once
+the code that has inhibitted quitting exits.
-+++
-** The list returned by `(match-data t)' now has the buffer as a final
-element, if the last match was on a buffer. `set-match-data'
-accepts such a list for restoring the match state.
+This is for use around potentially blocking or long-running code
+inside timer functions and `post-command-hook' functions.
+++
-** Variable aliases have been implemented:
+*** New macro `define-obsolete-function-alias'.
-*** defvaralias ALIAS-VAR BASE-VAR [DOCSTRING]
+This combines `defalias' and `make-obsolete'.
-This function defines the symbol ALIAS-VAR as a variable alias for
-symbol BASE-VAR. This means that retrieving the value of ALIAS-VAR
-returns the value of BASE-VAR, and changing the value of ALIAS-VAR
-changes the value of BASE-VAR.
++++
+*** New function `unsafep' determines whether a Lisp form is safe.
-DOCSTRING, if present, is the documentation for ALIAS-VAR; else it has
-the same documentation as BASE-VAR.
+It returns nil if the given Lisp form can't possibly do anything
+dangerous; otherwise it returns a reason why the form might be unsafe
+(calls unknown function, alters global variable, etc).
-*** indirect-variable VARIABLE
+*** `list-faces-display' takes an optional argument, REGEXP.
-This function returns the variable at the end of the chain of aliases
-of VARIABLE. If VARIABLE is not a symbol, or if VARIABLE is not
-defined as an alias, the function returns VARIABLE.
+If it is non-nil, the function lists only faces matching this regexp.
-It might be noteworthy that variables aliases work for all kinds of
-variables, including buffer-local and frame-local variables.
+** Lisp code indentation features:
+++
-*** The macro define-obsolete-variable-alias combines defvaralias and
-make-obsolete-variable. The macro define-obsolete-function-alias
-combines defalias and make-obsolete.
+*** The `defmacro' form can contain indentation and edebug declarations.
-+++
-** Enhancements to keymaps.
+These declarations specify how to indent the macro calls in Lisp mode
+and how to debug them with Edebug. You write them like this:
-*** Cleaner way to enter key sequences.
+ (defmacro NAME LAMBDA-LIST [DOC-STRING] [DECLARATION ...] ...)
-You can enter a constant key sequence in a more natural format, the
+DECLARATION is a list `(declare DECLARATION-SPECIFIER ...)'. The
+possible declaration specifiers are:
+
+(indent INDENT)
+ Set NAME's `lisp-indent-function' property to INDENT.
+
+(edebug DEBUG)
+ Set NAME's `edebug-form-spec' property to DEBUG. (This is
+ equivalent to writing a `def-edebug-spec' for the macro,
+ but this is cleaner.)
+
+---
+*** cl-indent now allows customization of Indentation of backquoted forms.
+
+See the new user option `lisp-backquote-indentation'.
+
+---
+*** cl-indent now handles indentation of simple and extended `loop' forms.
+
+The new user options `lisp-loop-keyword-indentation',
+`lisp-loop-forms-indentation', and `lisp-simple-loop-indentation' can
+be used to customize the indentation of keywords and forms in loop
+forms.
+
++++
+** Variable aliases:
+
+*** New function: defvaralias ALIAS-VAR BASE-VAR [DOCSTRING]
+
+This function defines the symbol ALIAS-VAR as a variable alias for
+symbol BASE-VAR. This means that retrieving the value of ALIAS-VAR
+returns the value of BASE-VAR, and changing the value of ALIAS-VAR
+changes the value of BASE-VAR.
+
+DOCSTRING, if present, is the documentation for ALIAS-VAR; else it has
+the same documentation as BASE-VAR.
+
+*** New function: indirect-variable VARIABLE
+
+This function returns the variable at the end of the chain of aliases
+of VARIABLE. If VARIABLE is not a symbol, or if VARIABLE is not
+defined as an alias, the function returns VARIABLE.
+
+It might be noteworthy that variables aliases work for all kinds of
+variables, including buffer-local and frame-local variables.
+
++++
+*** The macro `define-obsolete-variable-alias' combines `defvaralias' and
+`make-obsolete-variable'.
+
+** defcustom changes:
+
++++
+*** The new customization type `float' requires a floating point number.
+
+** String changes:
+
++++
+*** The escape sequence \s is now interpreted as a SPACE character.
+
+Exception: In a character constant, if it is followed by a `-' in a
+character constant (e.g. ?\s-A), it is still interpreted as the super
+modifier. In strings, \s is always interpreted as a space.
+
++++
+*** A hex escape in a string constant forces the string to be multibyte.
+
++++
+*** An octal escape in a string constant forces the string to be unibyte.
+
++++
+*** `split-string' now includes null substrings in the returned list if
+the optional argument SEPARATORS is non-nil and there are matches for
+SEPARATORS at the beginning or end of the string. If SEPARATORS is
+nil, or if the new optional third argument OMIT-NULLS is non-nil, all
+empty matches are omitted from the returned list.
+
++++
+*** New function `string-to-multibyte' converts a unibyte string to a
+multibyte string with the same individual character codes.
+
++++
+*** New function `substring-no-properties' returns a substring without
+text properties.
+
++++
+*** The new function `assoc-string' replaces `assoc-ignore-case' and
+`assoc-ignore-representation', which are still available, but have
+been declared obsolete.
+
++++
+** Displaying warnings to the user.
+
+See the functions `warn' and `display-warning', or the Lisp Manual.
+If you want to be sure the warning will not be overlooked, this
+facility is much better than using `message', since it displays
+warnings in a separate window.
+
++++
+** Progress reporters.
+
+These provide a simple and uniform way for commands to present
+progress messages for the user.
+
+See the new functions `make-progress-reporter',
+`progress-reporter-update', `progress-reporter-force-update',
+`progress-reporter-done', and `dotimes-with-progress-reporter'.
+
+** Buffer positions:
+
++++
+*** Function `compute-motion' now calculates the usable window
+width if the WIDTH argument is nil. If the TOPOS argument is nil,
+the usable window height and width is used.
+
++++
+*** The `line-move', `scroll-up', and `scroll-down' functions will now
+modify the window vscroll to scroll through display rows that are
+taller that the height of the window, for example in the presence of
+large images. To disable this feature, bind the new variable
+`auto-window-vscroll' to nil.
+
++++
+*** The argument to `forward-word', `backward-word' is optional.
+
+It defaults to 1.
+
++++
+*** Argument to `forward-to-indentation' and `backward-to-indentation' is optional.
+
+It defaults to 1.
+
++++
+*** New function `mouse-on-link-p' test if a position is in a clickable link.
+
+This is the function used by the new `mouse-1-click-follows-link'
+functionality.
+
++++
+*** New function `line-number-at-pos' returns the line number of a position.
+
+It an optional buffer position argument that defaults to point.
+
++++
+*** `field-beginning' and `field-end' take new optional argument, LIMIT.
+
+This argument tells them not to search beyond LIMIT. Instead they
+give up and return LIMIT.
+
++++
+*** Function `pos-visible-in-window-p' now returns the pixel coordinates
+and partial visiblity state of the corresponding row, if the PARTIALLY
+arg is non-nil.
+
++++
+*** New functions `posn-at-point' and `posn-at-x-y' return
+click-event-style position information for a given visible buffer
+position or for a given window pixel coordinate.
+
+** Text modification:
+
++++
+*** The new function `insert-for-yank' normally works like `insert', but
+removes the text properties in the `yank-excluded-properties' list
+and handles the `yank-handler' text property.
+
++++
+*** The new function `insert-buffer-substring-as-yank' is like
+`insert-for-yank' except that it gets the text from another buffer as
+in `insert-buffer-substring'.
+
++++
+*** The new function `insert-buffer-substring-no-properties' is like
+`insert-buffer-substring', but removes all text properties from the
+inserted substring.
+
++++
+*** The new function `filter-buffer-substring' extracts a buffer
+substring, passes it through a set of filter functions, and returns
+the filtered substring. Use it instead of `buffer-substring' or
+`delete-and-extract-region' when copying text into a user-accessible
+data structure, such as the kill-ring, X clipboard, or a register.
+
+The list of filter function is specified by the new variable
+`buffer-substring-filters'. For example, Longlines mode adds to
+`buffer-substring-filters' to remove soft newlines from the copied
+text.
+
++++
+*** Function `translate-region' accepts also a char-table as TABLE
+argument.
+
++++
+*** The new translation table `translation-table-for-input'
+is used for customizing self-insertion. The character to
+be inserted is translated through it.
+
+---
+*** Text clones.
+
+The new function `text-clone-create'. Text clones are chunks of text
+that are kept identical by transparently propagating changes from one
+clone to the other.
+
+---
+*** The function `insert-string' is now obsolete.
+
+** Filling changes.
+
++++
+*** In determining an adaptive fill prefix, Emacs now tries the function in
+`adaptive-fill-function' _before_ matching the buffer line against
+`adaptive-fill-regexp' rather than _after_ it.
+
++++
+** Atomic change groups.
+
+To perform some changes in the current buffer "atomically" so that
+they either all succeed or are all undone, use `atomic-change-group'
+around the code that makes changes. For instance:
+
+ (atomic-change-group
+ (insert foo)
+ (delete-region x y))
+
+If an error (or other nonlocal exit) occurs inside the body of
+`atomic-change-group', it unmakes all the changes in that buffer that
+were during the execution of the body. The change group has no effect
+on any other buffers--any such changes remain.
+
+If you need something more sophisticated, you can directly call the
+lower-level functions that `atomic-change-group' uses. Here is how.
+
+To set up a change group for one buffer, call `prepare-change-group'.
+Specify the buffer as argument; it defaults to the current buffer.
+This function returns a "handle" for the change group. You must save
+the handle to activate the change group and then finish it.
+
+Before you change the buffer again, you must activate the change
+group. Pass the handle to `activate-change-group' afterward to
+do this.
+
+After you make the changes, you must finish the change group. You can
+either accept the changes or cancel them all. Call
+`accept-change-group' to accept the changes in the group as final;
+call `cancel-change-group' to undo them all.
+
+You should use `unwind-protect' to make sure the group is always
+finished. The call to `activate-change-group' should be inside the
+`unwind-protect', in case the user types C-g just after it runs.
+(This is one reason why `prepare-change-group' and
+`activate-change-group' are separate functions.) Once you finish the
+group, don't use the handle again--don't try to finish the same group
+twice.
+
+To make a multibuffer change group, call `prepare-change-group' once
+for each buffer you want to cover, then use `nconc' to combine the
+returned values, like this:
+
+ (nconc (prepare-change-group buffer-1)
+ (prepare-change-group buffer-2))
+
+You can then activate the multibuffer change group with a single call
+to `activate-change-group', and finish it with a single call to
+`accept-change-group' or `cancel-change-group'.
+
+Nested use of several change groups for the same buffer works as you
+would expect. Non-nested use of change groups for the same buffer
+will lead to undesirable results, so don't let it happen; the first
+change group you start for any given buffer should be the last one
+finished.
+
+** Buffer-related changes:
+
+---
+*** `list-buffers-noselect' now takes an additional argument, BUFFER-LIST.
+
+If it is non-nil, it specifies which buffers to list.
+
++++
+*** `kill-buffer-hook' is now a permanent local.
+
++++
+*** The new function `buffer-local-value' returns the buffer-local
+binding of VARIABLE (a symbol) in buffer BUFFER. If VARIABLE does not
+have a buffer-local binding in buffer BUFFER, it returns the default
+value of VARIABLE instead.
+
+** Local variables lists:
+
++++
+*** Text properties in local variables.
+
+A file local variables list cannot specify a string with text
+properties--any specified text properties are discarded.
+
++++
+*** The variable `safe-local-eval-forms' specifies a list of forms that
+are ok to evaluate when they appear in an `eval' local variables
+specification. Normally Emacs asks for confirmation before evaluating
+such a form, but if the form appears in this list, no confirmation is
+needed.
+
+---
+*** If a function has a non-nil `safe-local-eval-function' property,
+that means it is ok to evaluate some calls to that function when it
+appears in an `eval' local variables specification. If the property
+is t, then any form calling that function with constant arguments is
+ok. If the property is a function or list of functions, they are called
+with the form as argument, and if any returns t, the form is ok to call.
+
+If the form is not "ok to call", that means Emacs asks for
+confirmation as before.
+
+** Searching and matching changes:
+
++++
+*** New function `looking-back' checks whether a regular expression matches
+the text before point. Specifying the LIMIT argument bounds how far
+back the match can start; this is a way to keep it from taking too long.
+
++++
+*** The new variable `search-spaces-regexp' controls how to search
+for spaces in a regular expression. If it is non-nil, it should be a
+regular expression, and any series of spaces stands for that regular
+expression. If it is nil, spaces stand for themselves.
+
+Spaces inside of constructs such as `[..]' and inside loops such as
+`*', `+', and `?' are never replaced with `search-spaces-regexp'.
+
++++
+*** New regular expression operators, `\_<' and `\_>'.
+
+These match the beginning and end of a symbol. A symbol is a
+non-empty sequence of either word or symbol constituent characters, as
+specified by the syntax table.
+
+---
+*** rx.el has new corresponding `symbol-end' and `symbol-start' elements.
+
++++
+*** `skip-chars-forward' and `skip-chars-backward' now handle
+character classes such as `[:alpha:]', along with individual
+characters and ranges.
+
+---
+*** In `replace-match', the replacement text no longer inherits
+properties from surrounding text.
+
++++
+*** The list returned by `(match-data t)' now has the buffer as a final
+element, if the last match was on a buffer. `set-match-data'
+accepts such a list for restoring the match state.
+
++++
+*** Functions `match-data' and `set-match-data' now have an optional
+argument `reseat'. When non-nil, all markers in the match data list
+passed to these function will be reseated to point to nowhere.
+
++++
+*** The default value of `sentence-end' is now defined using the new
+variable `sentence-end-without-space', which contains such characters
+that end a sentence without following spaces.
+
+The function `sentence-end' should be used to obtain the value of the
+variable `sentence-end'. If the variable `sentence-end' is nil, then
+this function returns the regexp constructed from the variables
+`sentence-end-without-period', `sentence-end-double-space' and
+`sentence-end-without-space'.
+
+** Undo changes:
+
++++
+*** `buffer-undo-list' can allows programmable elements.
+
+These elements have the form (apply FUNNAME . ARGS), where FUNNAME is
+a symbol other than t or nil. That stands for a high-level change
+that should be undone by evaluating (apply FUNNAME ARGS).
+
+These entries can also have the form (apply DELTA BEG END FUNNAME . ARGS)
+which indicates that the change which took place was limited to the
+range BEG...END and increased the buffer size by DELTA.
+
++++
+*** If the buffer's undo list for the current command gets longer than
+`undo-outer-limit', garbage collection empties it. This is to prevent
+it from using up the available memory and choking Emacs.
+
++++
+** New `yank-handler' text property can be used to control how
+previously killed text on the kill ring is reinserted.
+
+The value of the `yank-handler' property must be a list with one to four
+elements with the following format:
+ (FUNCTION PARAM NOEXCLUDE UNDO).
+
+The `insert-for-yank' function looks for a yank-handler property on
+the first character on its string argument (typically the first
+element on the kill-ring). If a `yank-handler' property is found,
+the normal behavior of `insert-for-yank' is modified in various ways:
+
+ When FUNCTION is present and non-nil, it is called instead of `insert'
+to insert the string. FUNCTION takes one argument--the object to insert.
+ If PARAM is present and non-nil, it replaces STRING as the object
+passed to FUNCTION (or `insert'); for example, if FUNCTION is
+`yank-rectangle', PARAM should be a list of strings to insert as a
+rectangle.
+ If NOEXCLUDE is present and non-nil, the normal removal of the
+`yank-excluded-properties' is not performed; instead FUNCTION is
+responsible for removing those properties. This may be necessary
+if FUNCTION adjusts point before or after inserting the object.
+ If UNDO is present and non-nil, it is a function that will be called
+by `yank-pop' to undo the insertion of the current object. It is
+called with two arguments, the start and end of the current region.
+FUNCTION can set `yank-undo-function' to override the UNDO value.
+
+*** The functions `kill-new', `kill-append', and `kill-region' now have an
+optional argument to specify the `yank-handler' text property to put on
+the killed text.
+
+*** The function `yank-pop' will now use a non-nil value of the variable
+`yank-undo-function' (instead of `delete-region') to undo the previous
+`yank' or `yank-pop' command (or a call to `insert-for-yank'). The function
+`insert-for-yank' automatically sets that variable according to the UNDO
+element of the string argument's `yank-handler' text property if present.
+
+*** The function `insert-for-yank' now supports strings where the
+`yank-handler' property does not span the first character of the
+string. The old behavior is available if you call
+`insert-for-yank-1' instead.
+
+** Syntax table changes:
+
++++
+*** The macro `with-syntax-table' no longer copies the syntax table.
+
++++
+*** The new function `syntax-after' returns the syntax code
+of the character after a specified buffer position, taking account
+of text properties as well as the character code.
+
++++
+*** `syntax-class' extracts the class of a syntax code (as returned
+by `syntax-after').
+
++++
+*** The new function `syntax-ppss' rovides an efficient way to find the
+current syntactic context at point.
+
+** File operation changes:
+
++++
+*** New vars `exec-suffixes' and `load-suffixes' used when
+searching for an executable or an Emacs Lisp file.
+
++++
+*** The new primitive `set-file-times' sets a file's access and
+modification times. Magic file name handlers can handle this
+operation.
+
++++
+*** The new function `file-remote-p' tests a file name and returns
+non-nil if it specifies a remote file (one that Emacs accesses using
+its own special methods and not directly through the file system).
+The value in that case is an identifier for the remote file system.
+
++++
+*** `buffer-auto-save-file-format' is the new name for what was
+formerly called `auto-save-file-format'. It is now a permanent local.
+
++++
+*** Functions `file-name-sans-extension' and `file-name-extension' now
+ignore the leading dots in file names, so that file names such as
+`.emacs' are treated as extensionless.
+
++++
+*** `copy-file' now takes an additional option arg MUSTBENEW.
+
+This argument works like the MUSTBENEW argument of write-file.
+
++++
+*** `visited-file-modtime' and `calendar-time-from-absolute' now return
+a list of two integers, instead of a cons.
+
++++
+*** `file-chase-links' now takes an optional second argument LIMIT which
+specifies the maximum number of links to chase through. If after that
+many iterations the file name obtained is still a symbolic link,
+`file-chase-links' returns it anyway.
+
++++
+*** The new hook `before-save-hook' is invoked by `basic-save-buffer'
+before saving buffers. This allows packages to perform various final
+tasks, for example; it can be used by the copyright package to make
+sure saved files have the current year in any copyright headers.
+
++++
+*** If `buffer-save-without-query' is non-nil in some buffer,
+`save-some-buffers' will always save that buffer without asking (if
+it's modified).
+
++++
+*** New function `locate-file' searches for a file in a list of directories.
+`locate-file' accepts a name of a file to search (a string), and two
+lists: a list of directories to search in and a list of suffixes to
+try; typical usage might use `exec-path' and `load-path' for the list
+of directories, and `exec-suffixes' and `load-suffixes' for the list
+of suffixes. The function also accepts a predicate argument to
+further filter candidate files.
+
+One advantage of using this function is that the list of suffixes in
+`exec-suffixes' is OS-dependant, so this function will find
+executables without polluting Lisp code with OS dependancies.
+
+---
+*** The precedence of file name handlers has been changed.
+
+Instead of choosing the first handler that matches,
+`find-file-name-handler' now gives precedence to a file name handler
+that matches nearest the end of the file name. More precisely, the
+handler whose (match-beginning 0) is the largest is chosen. In case
+of ties, the old "first matched" rule applies.
+
++++
+*** A file name handler can declare which operations it handles.
+
+You do this by putting an `operation' property on the handler name
+symbol. The property value should be a list of the operations that
+the handler really handles. It won't be called for any other
+operations.
+
+This is useful for autoloaded handlers, to prevent them from being
+autoloaded when not really necessary.
+
+** Input changes:
+
++++
+*** An interactive specification can now use the code letter 'U' to get
+the up-event that was discarded in case the last key sequence read for a
+previous `k' or `K' argument was a down-event; otherwise nil is used.
+
++++
+*** The new interactive-specification `G' reads a file name
+much like `F', but if the input is a directory name (even defaulted),
+it returns just the directory name.
+
+---
+*** Functions `y-or-n-p', `read-char', `read-key-sequence' and the like, that
+display a prompt but don't use the minibuffer, now display the prompt
+using the text properties (esp. the face) of the prompt string.
+
++++
+*** (while-no-input BODY...) runs BODY, but only so long as no input
+arrives. If the user types or clicks anything, BODY stops as if a
+quit had occurred. `while-no-input' returns the value of BODY, if BODY
+finishes. It returns nil if BODY was aborted.
+
+** Minibuffer changes:
+
++++
+*** The new function `minibufferp' returns non-nil if its optional
+buffer argument is a minibuffer. If the argument is omitted, it
+defaults to the current buffer.
+
++++
+*** New function `minibuffer-selected-window' returns the window which
+was selected when entering the minibuffer.
+
++++
+*** `read-from-minibuffer' now accepts an additional argument KEEP-ALL
+saying to put all inputs in the history list, even empty ones.
+
++++
+*** The `read-file-name' function now takes an additional argument which
+specifies a predicate which the file name read must satify. The
+new variable `read-file-name-predicate' contains the predicate argument
+while reading the file name from the minibuffer; the predicate in this
+variable is used by read-file-name-internal to filter the completion list.
+
+---
+*** The new variable `read-file-name-function' can be used by Lisp code
+to override the built-in `read-file-name' function.
+
++++
+*** The new variable `read-file-name-completion-ignore-case' specifies
+whether completion ignores case when reading a file name with the
+`read-file-name' function.
+
++++
+*** The new function `read-directory-name' for reading a directory name.
+
+It is like `read-file-name' except that the defaulting works better
+for directories, and completion inside it shows only directories.
+
+** Completion changes:
+
++++
+*** The functions `all-completions' and `try-completion' now accept lists
+of strings as well as hash-tables additionally to alists, obarrays
+and functions. Furthermore, the function `test-completion' is now
+exported to Lisp. The keys in alists and hash tables can be either
+strings or symbols, which are automatically converted with to strings.
+
++++
+*** The new macro `dynamic-completion-table' supports using functions
+as a dynamic completion table.
+
+ (dynamic-completion-table FUN)
+
+FUN is called with one argument, the string for which completion is required,
+and it should return an alist containing all the intended possible
+completions. This alist can be a full list of possible completions so that FUN
+can ignore the value of its argument. If completion is performed in the
+minibuffer, FUN will be called in the buffer from which the minibuffer was
+entered. `dynamic-completion-table' then computes the completion.
+
++++
+*** The new macro `lazy-completion-table' initializes a variable
+as a lazy completion table.
+
+ (lazy-completion-table VAR FUN &rest ARGS)
+
+If the completion table VAR is used for the first time (e.g., by passing VAR
+as an argument to `try-completion'), the function FUN is called with arguments
+ARGS. FUN must return the completion table that will be stored in VAR. If
+completion is requested in the minibuffer, FUN will be called in the buffer
+from which the minibuffer was entered. The return value of
+`lazy-completion-table' must be used to initialize the value of VAR.
+
++++
+** Enhancements to keymaps.
+
+*** Cleaner way to enter key sequences.
+
+You can enter a constant key sequence in a more natural format, the
same one used for saving keyboard macros, using the macro `kbd'. For
example,
*** Interactive commands can be remapped through keymaps.

Example:
-Suppose that minor mode my-mode has defined the commands
-my-kill-line and my-kill-word, and it wants C-k (and any other key

+Suppose that minor mode `my-mode' has defined the commands

+bound to `kill-line') to run the command `my-kill-line' instead of
+`kill-line', and likewise it wants to run `my-kill-word' instead of
+`kill-word'.
Instead of rebinding C-k and the other keys in the minor mode map,
-command remapping allows you to directly map kill-line into
-my-kill-line and kill-word into my-kill-word through the minor mode
-map using define-key:
+command remapping allows you to directly map `kill-line' into
+`my-kill-line' and `kill-word' into `my-kill-word' using `define-key':
(define-key my-mode-map [remap kill-line] 'my-kill-line)
(define-key my-mode-map [remap kill-word] 'my-kill-word)
-Now, when my-mode is enabled, and the user enters C-k or M-d,
-the commands my-kill-line and my-kill-word are run.
+When `my-mode' is enabled, its minor mode keymap is enabled too. So
+when the user types C-k, that runs the command `my-kill-line'.
-Notice that only one level of remapping is supported. In the above
-example, this means that if my-kill-line is remapped to other-kill,
-then C-k still runs my-kill-line.
+Only one level of remapping is supported. In the above example, this
+means that if `my-kill-line' is remapped to `other-kill', then C-k still
+runs `my-kill-line'.
The following changes have been made to provide command remapping:
- The new function `command-remapping' returns the binding for a
remapped command in the current keymaps, or nil if not remapped.
-- key-binding now remaps interactive commands unless the optional
+- `key-binding' now remaps interactive commands unless the optional
third argument NO-REMAP is non-nil.

+ `kill-line', when `my-mode' is enabled), and the actual key binding for
the command it is remapped to (e.g. C-k for my-kill-line).
It also has a new optional fifth argument, NO-REMAP, which inhibits
- remapping if non-nil (e.g. it returns C-k for kill-line and
- <kill-line> for my-kill-line).
+ remapping if non-nil (e.g. it returns "C-k" for `kill-line', and
+ "<kill-line>" for `my-kill-line').
- The new variable `this-original-command' contains the original
command before remapping. It is equal to `this-command' when the

*** Dense keymaps now handle inheritance correctly.
+
Previously a dense keymap would hide all of the simple-char key
bindings of the parent keymap.
*** New function `describe-buffer-bindings' inserts the list of all
defined keys and their definitions.

Lisp packages using many minor mode keymaps can now maintain their own
-keymap alist separate from minor-mode-map-alist by adding their keymap
-alist to this list.

-+++
-** Atomic change groups.
-
-To perform some changes in the current buffer "atomically" so that
-they either all succeed or are all undone, use `atomic-change-group'
-around the code that makes changes. For instance:
-
- (atomic-change-group
- (insert foo)
- (delete-region x y))
-
-If an error (or other nonlocal exit) occurs inside the body of
-`atomic-change-group', it unmakes all the changes in that buffer that
-were during the execution of the body. The change group has no effect
-on any other buffers--any such changes remain.
-
-If you need something more sophisticated, you can directly call the
-lower-level functions that `atomic-change-group' uses. Here is how.
-
-To set up a change group for one buffer, call `prepare-change-group'.
-Specify the buffer as argument; it defaults to the current buffer.
-This function returns a "handle" for the change group. You must save
-the handle to activate the change group and then finish it.
-
-Before you change the buffer again, you must activate the change
-group. Pass the handle to `activate-change-group' afterward to
-do this.
-
-After you make the changes, you must finish the change group. You can
-either accept the changes or cancel them all. Call
-`accept-change-group' to accept the changes in the group as final;
-call `cancel-change-group' to undo them all.
-
-You should use `unwind-protect' to make sure the group is always
-finished. The call to `activate-change-group' should be inside the
-`unwind-protect', in case the user types C-g just after it runs.
-(This is one reason why `prepare-change-group' and
-`activate-change-group' are separate functions.) Once you finish the
-group, don't use the handle again--don't try to finish the same group
-twice.
-
-To make a multibuffer change group, call `prepare-change-group' once
-for each buffer you want to cover, then use `nconc' to combine the
-returned values, like this:
-
- (nconc (prepare-change-group buffer-1)
- (prepare-change-group buffer-2))
-
-You can then activate the multibuffer change group with a single call
-to `activate-change-group', and finish it with a single call to
-`accept-change-group' or `cancel-change-group'.
-
-Nested use of several change groups for the same buffer works as you
-would expect. Non-nested use of change groups for the same buffer

-a command to present progress messages for the user.
+** Abbrev changes:
+++
-** New `yank-handler' text property can be used to control how
-previously killed text on the kill-ring is reinserted.
-
-The value of the yank-handler property must be a list with one to four
-elements with the following format:
- (FUNCTION PARAM NOEXCLUDE UNDO).
-
-The `insert-for-yank' function looks for a yank-handler property on
-the first character on its string argument (typically the first
-element on the kill-ring). If a yank-handler property is found,
-the normal behavior of `insert-for-yank' is modified in various ways:
-
- When FUNCTION is present and non-nil, it is called instead of `insert'
-to insert the string. FUNCTION takes one argument--the object to insert.
- If PARAM is present and non-nil, it replaces STRING as the object
-passed to FUNCTION (or `insert'); for example, if FUNCTION is
-`yank-rectangle', PARAM should be a list of strings to insert as a
-rectangle.
- If NOEXCLUDE is present and non-nil, the normal removal of the
-yank-excluded-properties is not performed; instead FUNCTION is
-responsible for removing those properties. This may be necessary
-if FUNCTION adjusts point before or after inserting the object.
- If UNDO is present and non-nil, it is a function that will be called
-by `yank-pop' to undo the insertion of the current object. It is
-called with two arguments, the start and end of the current region.
-FUNCTION can set `yank-undo-function' to override the UNDO value.
-
-*** The functions kill-new, kill-append, and kill-region now have an
-optional argument to specify the yank-handler text property to put on
-the killed text.
-
-*** The function yank-pop will now use a non-nil value of the variable
-`yank-undo-function' (instead of delete-region) to undo the previous
-yank or yank-pop command (or a call to insert-for-yank). The function
-insert-for-yank automatically sets that variable according to the UNDO
-element of the string argument's yank-handler text property if present.
-
-*** The function `insert-for-yank' now supports strings where the
-`yank-handler' property does not span the first character of the
-string. The old behavior is available if you call
-`insert-for-yank-1' instead.
+*** The new function `copy-abbrev-table' copies an abbrev table.
-*** The new function insert-for-yank normally works like `insert', but
-removes the text properties in the `yank-excluded-properties' list.
-However, the insertion of the text can be modified by a `yank-handler'
-text property.
+It returns a new abbrev table that is a copy of a given abbrev table.
+++
-** An element of buffer-undo-list can now have the form (apply FUNNAME
-. ARGS), where FUNNAME is a symbol other than t or nil. That stands
-for a high-level change that should be undone by evaluating (apply
-FUNNAME ARGS).
+*** `define-abbrev' now accepts an optional argument SYSTEM-FLAG.
-These entries can also have the form (apply DELTA BEG END FUNNAME . ARGS)
-which indicates that the change which took place was limited to the
-range BEG...END and increased the buffer size by DELTA.
-
-+++
-** If the buffer's undo list for the current command gets longer than
-undo-outer-limit, garbage collection empties it. This is to prevent
-it from using up the available memory and choking Emacs.
+If non-nil, this marks the abbrev as a "system" abbrev, which means
+that it won't be stored in the user's abbrevs file if he saves the
+abbrevs. Major modes that predefine some abbrevs should always
+specify this flag.
+++
** Enhancements to process support
-*** Function list-processes now has an optional argument; if non-nil,
-only the processes whose query-on-exit flag is set are listed.
+*** Function `list-processes' now has an optional argument; if non-nil,
+it lists only the processes whose query-on-exit flag is set.
-*** New set-process-query-on-exit-flag and process-query-on-exit-flag

-the text before point. Specifying the LIMIT argument bounds how far
-back the match can start; this is a way to keep it from taking too long.
+** Miscellaneous:
+++
-*** New function `macroexpand-all' expands all macros in a form.
-It is similar to the Common-Lisp function of the same name.
-One difference is that it guarantees to return the original argument
-if no expansion is done, which can be tested using `eq'.
+*** A number of hooks have been renamed to better follow the conventions:
-*** The new function `minibufferp' returns non-nil if its optional
-buffer argument is a minibuffer. If the argument is omitted, it
-defaults to the current buffer.
+`find-file-hooks' to `find-file-hook',
+`find-file-not-found-hooks' to `find-file-not-found-functions',
+`write-file-hooks' to `write-file-functions',
+`write-contents-hooks' to `write-contents-functions',
+`x-lost-selection-hooks' to `x-lost-selection-functions',
+`x-sent-selection-hooks' to `x-sent-selection-functions',
+`delete-frame-hook' to `delete-frame-functions'.
-+++
-*** New function minibuffer-selected-window returns the window which
-was selected when entering the minibuffer.
+In each case the old name remains as an alias for the moment.
+++
-*** The new function `modify-all-frames-parameters' modifies parameters
-for all (existing and future) frames.
+*** local-write-file-hooks is marked obsolete
-+++
-*** New functions posn-at-point and posn-at-x-y return
-click-event-style position information for a given visible buffer
-position or for a given window pixel coordinate.
+Use the LOCAL arg of `add-hook'.
---
-*** New function quail-find-key returns a list of keys to type in the
-current input method to input a character.
-
-+++
-*** The new function `rassq-delete-all' deletes all elements from an
-alist whose cdr is `eq' to a specified value.
-
-+++
-*** The new function remove-list-of-text-properties is almost the same
-as `remove-text-properties'. The only difference is that it takes a
-list of property names as argument rather than a property list.
-
-+++
-*** The new primitive `set-file-times' sets a file's access and
-modification times. Magic file name handlers can handle this
-operation.
-
-+++
-*** New function substring-no-properties returns a substring without
-text properties.
+*** New function `x-send-client-message' sends a client message when
+running under X.
-+++
-*** The new function syntax-after returns the syntax code
-of the character after a specified buffer position, taking account
-of text properties as well as the character code.
+** GC changes:
+++
-*** `syntax-class' extracts the class of a syntax code (as returned
-by syntax-after).
+*** New variables `gc-elapsed' and `gcs-done' provide extra information
+on garbage collection.
+++
-*** New function `tool-bar-local-item-from-menu'
+*** The normal hook `post-gc-hook' is run at the end of garbage collection.
-The `tool-bar-add-item-from-menu' must not be used (as previously
-recommended) for making entries in the tool bar for local keymaps.
-Instead, use the function `tool-bar-local-item-from-menu', which lets
-you specify the map to use as an argument.
+The hook is run with GC inhibited, so use it with care.

+* New Packages for Lisp Programming in Emacs 22.1
+++
-*** New function window-body-height.
-This is like window-height but does not count the mode line
-or the header line.
+** The new library button.el implements simple and fast `clickable
+buttons' in emacs buffers. Buttons are much lighter-weight than the
+`widgets' implemented by widget.el, and can be used by lisp code that
+doesn't require the full power of widgets. Emacs uses buttons for
+such things as help and apropos buffers.
-+++
-*** (while-no-input BODY...) runs BODY, but only so long as no input
-arrives. If the user types or clicks anything, BODY stops as if a
-quit had occurred. while-no-input returns the value of BODY, if BODY
-finishes. It returns nil if BODY was aborted.
+---
+** The new library tree-widget.el provides a widget to display a set
+of hierarchical data as an outline. For example, the tree-widget is
+well suited to display a hierarchy of directories and files.
+++
-*** New macro with-local-quit temporarily sets inhibit-quit to nil for use
-around potentially blocking or long-running code in timers
-and post-command-hooks.
-
-** New packages:
-
-*** The new package syntax.el provides an efficient way to find the
-current syntactic context (as returned by parse-partial-sexp).
-
-*** The new package bindat.el provides functions to unpack and pack
+** The new library bindat.el provides functions to unpack and pack
binary data structures, such as network packets, to and from Lisp
data structures.
---
-*** The TCL package tcl-mode.el was replaced by tcl.el.
-This was actually done in Emacs-21.1, and was not documented.
-
-+++
-*** The new package button.el implements simple and fast `clickable buttons'
-in emacs buffers. `buttons' are much lighter-weight than the `widgets'
-implemented by widget.el, and can be used by lisp code that doesn't
-require the full power of widgets. Emacs uses buttons for such things

+** master-mode.el implements a minor mode for scrolling a slave
buffer without leaving your current buffer, the master buffer.
It can be used by sql.el, for example: the SQL buffer is the master

+++
-*** New Lisp library testcover.el works with edebug to help you determine
-whether you've tested all your Lisp code. Function testcover-start
-instruments all functions in a given file. Then test your code. Function
-testcover-mark-all adds overlay "splotches" to the Lisp file's buffer to
-show where coverage is lacking. Command testcover-next-mark (bind it to
-a key!) will move point forward to the next spot that has a splotch.
+** The new library benchmark.el does timing measurements on Lisp code.

Normally, a red splotch indicates the form was never completely
evaluated; a brown splotch means it always evaluated to the same
For difficult cases, you can add do-nothing macros to your code to
help out the test coverage tool. The macro `noreturn' suppresses a
red splotch. It is an error if the argument to `noreturn' does
-return. The macro 1value suppresses a brown splotch for its argument.

This macro is a no-op except during test-coverage -- then it signals
an error if the argument actually returns differing values.
