- This section briefly describes the peculiarities of using Emacs
-under Mac OS with native window system support. For Mac OS X, Emacs
-can be built either without window system support, with X11, or with
-Carbon API. This section only applies to the Carbon build. For Mac
-OS Classic, Emacs can be built with or without Carbon API, and this
-section applies to either of them because they run on the native
-window system.
-
- Emacs built on Mac OS X supports most of its major features except
-display support of PostScript images. The following features of Emacs
-are not supported on Mac OS Classic: unexec (@code{dump-emacs}),
-asynchronous subprocesses (@code{start-process}), and networking
-(@code{open-network-stream}). As a result, packages such as Gnus,
-GUD, and Comint do not work. Synchronous subprocesses
-(@code{call-process}) are supported on non-Carbon build, but
-specially-crafted external programs are needed. Since external
-programs to handle commands such as @code{print-buffer} and
-@code{diff} are not available on Mac OS Classic, they are not
-supported. Non-Carbon build on Mac OS Classic does not support some
-features such as file dialogs, drag-and-drop, and Unicode menus.

-
-@vindex mac-control-modifier
-@vindex mac-command-modifier
-@vindex mac-option-modifier
-@vindex mac-function-modifier
- On Mac, Emacs can use @key{control}, @key{command}, @key{option}, and
-laptop @key{function} keys as any of Emacs modifier keys except
-@key{SHIFT} (i.e., @key{ALT}, @key{CTRL}, @key{HYPER}, @key{META}, and
-@key{SUPER}). The assignment is controlled by the variables
-@code{mac-control-modifier}, @code{mac-command-modifier},
-@code{mac-option-modifier}, and @code{mac-function-modifier}. The value
-for each of these variables can be one of the following symbols:
-@code{alt}, @code{control}, @code{hyper}, @code{meta}, @code{super}, and
-@code{nil} (no particular assignment). By default, the @key{control}
-key works as @key{CTRL}, and the @key{command} key as @key{META}.
-
- For the @key{option} key, if @code{mac-option-modifier} is set to
-@code{nil}, which is the default, the key works as the normal
-@key{option} key, i.e., dead-key processing will work. This is useful
-for entering non-@acronym{ASCII} Latin characters directly from the
-Mac keyboard, for example.
-
- Emacs recognizes the setting in the Keyboard control panel (Mac OS
-Classic) or the International system preference pane (Mac OS X) and
-supports international and alternative keyboard layouts (e.g., Dvorak).
-Selecting one of the layouts from the keyboard layout pull-down menu
-will affect how the keys typed on the keyboard are interpreted.
-
-@vindex mac-pass-command-to-system
-@vindex mac-pass-control-to-system
- Mac OS intercepts and handles certain key combinations (e.g.,
-@key{command}-@key{SPC} for switching input languages). These will not
-be passed to Emacs. One can disable this interception by setting
-@code{mac-pass-command-to-system} or @code{mac-pass-control-to-system}
-to @code{nil}.
-
-@vindex mac-emulate-three-button-mouse
- Especially for one-button mice, the multiple button feature can be
-emulated by setting @code{mac-emulate-three-button-mouse} to @code{t}
-or @code{reverse}. If set to @code{t} (@code{reverse}, respectively),
-pressing the mouse button with the @key{option} key is recognized as
-the second (third) button, and that with the @key{command} key is
-recognized as the third (second) button.
-
-@vindex mac-wheel-button-is-mouse-2
- For multi-button mice, the wheel button and the secondary button are
-recognized as the second and the third button, respectively. If
-@code{mac-wheel-button-is-mouse-2} is set to @code{nil}, their roles
-are exchanged.
-
-@node Mac International
-@section International Character Set Support on Mac
-@cindex Mac Roman coding system
-@cindex clipboard support (Mac OS)
-
- Mac uses non-standard encodings for the upper 128 single-byte
-characters. They also deviate from the ISO 2022 standard by using
-character codes in the range 128-159. The coding systems
-@code{mac-roman}, @code{mac-centraleurroman}, and @code{mac-cyrillic}
-are used to represent these Mac encodings.
-
- You can use input methods provided either by LEIM (@pxref{Input
-Methods}) or Mac OS to enter international characters. To use the
-former, see the International Character Set Support section of the
-manual (@pxref{International}).
-
- Emacs on Mac OS automatically changes the value of
-@code{keyboard-coding-system} according to the current keyboard
-layout. So users don't need to set it manually, and even if set, it
-will be changed when the keyboard layout change is detected next time.
-
- The Mac clipboard and the Emacs kill ring (@pxref{Killing}) are
-synchronized by default: you can yank a piece of text and paste it
-into another Mac application, or cut or copy one in another Mac
-application and yank it into a Emacs buffer. This feature can be
-disabled by setting @code{x-select-enable-clipboard} to @code{nil}.
-One can still do copy and paste with another application from the Edit
-menu.
-
- On Mac, the role of the coding system for selection that is set by
-@code{set-selection-coding-system} (@pxref{Communication Coding}) is
-two-fold. First, it is used as a preferred coding system for the
-traditional text flavor that does not specify any particular encodings
-and is mainly used by applications on Mac OS Classic. Second, it
-specifies the intermediate encoding for the UTF-16 text flavor that is
-mainly used by applications on Mac OS X.
-
- When pasting UTF-16 text data from the clipboard, it is first
-converted to the encoding specified by the selection coding system
-using the converter in the Mac OS system, and then decoded into the
-Emacs internal encoding using the converter in Emacs. If the first
-conversion failed, then the UTF-16 data is directly converted to Emacs
-internal encoding using the converter in Emacs. Copying UTF-16 text
-to the clipboard goes through the inverse path. The reason for this
-two-pass decoding is to avoid subtle differences in Unicode mappings
-between the Mac OS system and Emacs such as various kinds of hyphens,
-and to minimize users' customization. For example, users that mainly
-use Latin characters would prefer Greek characters to be decoded into
-the @code{mule-unicode-0100-24ff} charset, but Japanese users would
-prefer them to be decoded into the @code{japanese-jisx0208} charset.
-Since the coding system for selection is automatically set according
-to the system locale setting, users usually don't have to set it
-manually.
-
- The default language environment (@pxref{Language Environments}) is
-set according to the locale setting at the startup time. On Mac OS,
-the locale setting is consulted in the following order:
-
-@enumerate
-@item
-Environment variables @env{LC_ALL}, @env{LC_CTYPE} and @env{LANG} as
-in other systems.
-
-@item
-Preference @code{AppleLocale} that is set by default on Mac OS X 10.3
-and later.
-
-@item
-Preference @code{AppleLanguages} that is set by default on Mac OS X
-10.1 and later.
-
-@item
-Variable @code{mac-system-locale} that is derived from the system
-language and region codes. This variable is available on all
-supported Mac OS versions including Mac OS Classic.
-@end enumerate
-
- The default values of almost all variables about coding systems are
-also set according to the language environment. So usually you don't
-have to customize these variables manually.
-
-@node Mac Environment Variables
-@section Environment Variables and Command Line Arguments.
-@cindex environment variables (Mac OS)
-
- On Mac OS X, when Emacs is run in a terminal, it inherits the values
-of environment variables from the shell from which it is invoked.
-However, when it is run from the Finder as a GUI application, it only
-inherits environment variable values defined in the file
-@file{~/.MacOSX/environment.plist} that affects all the applications
-invoked from the Finder or the @command{open} command.
-
- Command line arguments are specified like
-
-@example
-/Applications/Emacs.app/Contents/MacOS/Emacs -g 80x25 &
-@end example
-
-@noindent
-if Emacs is installed at @file{/Applications/Emacs.app}. If Emacs is
-invoked like this, then it also inherits the values of environment
-variables from the shell from which it is invoked.
-
- On Mac OS Classic, environment variables and command line arguments
-for Emacs can be set by modifying the @samp{STR#} resources 128 and
-129, respectively. A common environment variable that one may want to
-set is @samp{HOME}.
-
- The way to set an environment variable is by adding a string of the
-form
-
-@example
-ENV_VAR=VALUE
-@end example
-
-@noindent
-to resource @samp{STR#} number 128 using @code{ResEdit}. To set up the
-program to use unibyte characters exclusively, for example, add the
-string
-
-@example
-EMACS_UNIBYTE=1
-@end example
-
-@cindex Mac Preferences
- Although Emacs on Mac does not support X resources (@pxref{X
-Resources}) directly, one can use the Preferences system in place of X
-resources. For example, adding the line
-
-@example
-Emacs.cursorType: bar
-@end example
-
-@noindent
-to @file{~/.Xresources} in X11 corresponds to the execution of
-
-@example
-defaults write org.gnu.Emacs Emacs.cursorType bar
-@end example
-
-@noindent
-on Mac OS X. One can use boolean or numeric values as well as string
-values as follows:
-
-@example
-defaults write org.gnu.Emacs Emacs.toolBar -bool false
-defaults write org.gnu.Emacs Emacs.lineSpacing -int 3
-@end example
-
-@noindent
-Try @kbd{M-x man RET defaults RET} for the usage of the
-@command{defaults} command. Alternatively, if you have Developer
-Tools installed on Mac OS X, you can use Property List Editor to edit
-the file @file{~/Library/Preferences/org.gnu.Emacs.plist}.
-
-
-@node Mac Directories
-@section Volumes and Directories on Mac
-@cindex file names (Mac OS)
-
- This node applies to Mac OS Classic only.
-
- The directory structure in Mac OS Classic is seen by Emacs as
-
-@example
-/@var{volumename}/@var{filename}
-@end example
-
-So when Emacs requests a file name, doing file name completion on
-@file{/} will display all volumes on the system. You can use @file{..}
-to go up a directory level.
-
- On Mac OS Classic, to access files and folders on the desktop, look
-in the folder @file{Desktop Folder} in your boot volume (this folder
-is usually invisible in the Mac @code{Finder}).
-
- On Mac OS Classic, Emacs creates the Mac folder
-@file{:Preferences:Emacs:} in the @file{System Folder} and uses it as
-the temporary directory. Emacs maps the directory name @file{/tmp/}
-to that. Therefore it is best to avoid naming a volume @file{tmp}.
-If everything works correctly, the program should leave no files in it
-when it exits. You should be able to set the environment variable
-@code{TMPDIR} to use another directory but this folder will still be
-created.
-
-
-@node Mac Font Specs
-@section Specifying Fonts on Mac
-@cindex font names (Mac OS)
-
- It is rare that you need to specify a font name in Emacs; usually
-you specify face attributes instead. For example, you can use 14pt
-Courier by customizing the default face attributes for all frames:
-
-@lisp
-(set-face-attribute 'default nil
- :family "courier" :height 140)
-@end lisp
-
-@noindent
-Alternatively, an interactive one is also available
-(@pxref{Face Customization}).
-
-But when you do need to specify a font name in Emacs on Mac, use a
-standard X font name:
-
-@smallexample
--@var{maker}-@var{family}-@var{weight}-@var{slant}-@var{widthtype}-@var{style}@dots{}
-@dots{}-@var{pixels}-@var{height}-@var{horiz}-@var{vert}-@var{spacing}-@var{width}-@var{charset}
-@end smallexample
-
-@noindent
-@xref{Font X}. Wildcards are supported as they are on X.
-
- Emacs on Mac OS Classic uses QuickDraw Text routines for drawing texts
-by default. Emacs on Mac OS X uses @acronym{ATSUI, Apple Type Services
-for Unicode Imaging} as well as QuickDraw Text, and most of the
-characters other than Chinese, Japanese, and Korean ones are drawn using
-the former by default.
-
- @acronym{ATSUI}-compatible fonts have maker name @code{apple} and
-charset @code{iso10646-1}. For example, 12-point Monaco can be specified
-by the name:
-
-@example
--apple-monaco-medium-r-normal--12-*-*-*-*-*-iso10646-1
-@end example
-
-Note that these names must be specified using a format containing all
-14 @samp{-}s (not by
-@samp{-apple-monaco-medium-r-normal--12-*-iso10646-1}, for instance),
-because every @acronym{ATSUI}-compatible font is a scalable one.
-
- QuickDraw Text fonts have maker name @code{apple} and various charset
-names other than @code{iso10646-1}. Native Apple fonts in Mac Roman
-encoding has charset @code{mac-roman}. You can specify a
-@code{mac-roman} font for @acronym{ASCII} characters like
-
-@smalllisp
-(add-to-list
- 'default-frame-alist
- '(font . "-apple-monaco-medium-r-normal--13-*-*-*-*-*-mac-roman"))
-@end smalllisp
-
-@noindent
-but that does not extend to ISO-8859-1: specifying a @code{mac-roman}
-font for Latin-1 characters introduces wrong glyphs.
-
- Native Apple Traditional Chinese, Simplified Chinese, Japanese,
-Korean, Central European, Cyrillic, Symbol, and Dingbats fonts have
-the charsets @samp{big5-0}, @samp{gb2312.1980-0},
-@samp{jisx0208.1983-sjis} and @samp{jisx0201.1976-0},
-@samp{ksc5601.1989-0}, @samp{mac-centraleurroman},
-@samp{mac-cyrillic}, @samp{mac-symbol}, and @samp{mac-dingbats},
-respectively.
-
- The use of @code{create-fontset-from-fontset-spec} (@pxref{Defining
-Fontsets}) for defining fontsets often results in wrong ones especially
-when using only OS-bundled QuickDraw Text fonts. The recommended way to
-use them is to create a fontset using
-@code{create-fontset-from-mac-roman-font}:
-
-@lisp
-(create-fontset-from-mac-roman-font
- "-apple-courier-medium-r-normal--13-*-*-*-*-*-mac-roman"
- nil "foo")
-@end lisp
-
-@noindent
-and then optionally specifying Chinese, Japanese, or Korean font
-families using @code{set-fontset-font}:
-
-@lisp
-(set-fontset-font "fontset-foo"
- 'chinese-gb2312 '("song" . "gb2312.1980-0"))
-@end lisp
-
- Single-byte fonts converted from GNU fonts in BDF format, which are not
-in the Mac Roman encoding, have foundry, family, and character sets
-encoded in the names of their font suitcases. E.g., the font suitcase
-@samp{ETL-Fixed-ISO8859-1} contains fonts which can be referred to by
-the name @samp{-ETL-fixed-*-iso8859-1}.
-
-@vindex mac-allow-anti-aliasing
- Mac OS X 10.2 or later can use two types of text renderings: Quartz 2D
-(aka Core Graphics) and QuickDraw. By default, Emacs uses the former on
-such versions. It can be changed by setting
-@code{mac-allow-anti-aliasing} to @code{t} (Quartz 2D) or @code{nil}
-(QuickDraw). Both @acronym{ATSUI} and QuickDraw Text drawings are
-affected by the value of this variable.
-
- Appearance of text in small sizes will also be affected by the ``Turn
-off text smoothing for font sizes @var{n} and smaller'' setting in the
-General pane (Mac OS X 10.1 or 10.2) or in the Appearance pane (10.3 or
-later) of the System Preferences. This threshold can alternatively be
-set just for Emacs (i.e., not as the system-wide setting) using the
-@command{defaults} command:
-
-@example
-defaults write org.gnu.Emacs AppleAntiAliasingThreshold @var{n}
-@end example
-
-
-@node Mac Functions
-@section Mac-Specific Lisp Functions
-@cindex Lisp functions specific to Mac OS
-
-@findex do-applescript
- The function @code{do-applescript} takes a string argument,
-executes it as an AppleScript command, and returns the result as a
-string.
-
-@findex mac-file-name-to-posix
-@findex posix-file-name-to-mac
- The function @code{mac-file-name-to-posix} takes a Mac file name and
-returns the GNU or Unix equivalent. The function
-@code{posix-file-name-to-mac} performs the opposite conversion. They
-are useful for constructing AppleScript commands to be passed to
-@code{do-applescript}.
-
-@findex mac-set-file-creator
-@findex mac-get-file-creator
-@findex mac-set-file-type
-@findex mac-get-file-type
- The functions @code{mac-set-file-creator},
-@code{mac-get-file-creator}, @code{mac-set-file-type}, and
-@code{mac-get-file-type} can be used to set and get creator and file
-codes.
-
-@findex mac-get-preference
- The function @code{mac-get-preference} returns the preferences value
-converted to a Lisp object for a specified key and application.

+@cindex Macintosh
+@cindex GNUstep
+
+ This section describes the peculiarities of using Emacs built with
+the GNUstep libraries on GNU/Linux or other operating systems, or on
+Mac OS X with native window system support. On Mac OS X, Emacs can be
+built either without window system support, with X11, or with the
+Cocoa interface; this section only applies to the Cocoa build. Emacs
+does not support earlier versions of Mac OS.
+
+ For various historical and technical reasons, Emacs uses the term
+@samp{Nextstep} internally, instead of ``Cocoa'' or ``Mac OS X''; for
+instance, most of the commands and variables described in this section
+begin with @samp{ns-}, which is short for @samp{Nextstep}. NeXTstep
+was an application interface released by NeXT Inc during the 1980s, of
+which Cocoa is a direct descendant. Apart from Cocoa, there is
+another NeXTstep-style system: GNUstep, which is free software. As of
+this writing, the GNUstep support is alpha status (@pxref{GNUstep
+Support}), but we hope to improve it in the future.

+
+@node Mac / GNUstep Basics, Mac / GNUstep Customization, , Mac OS / GNUstep
+@section Basic Emacs usage under Mac OS and GNUstep
+
+ By default, the @key{alt} and @key{option} keys are the same as
+@key{Meta}. The Mac @key{Cmd} key is the same as @key{Super}, and
+Emacs provides a set of keybindings using this modifier key that mimic
+other Mac / GNUstep applications (@pxref{Mac / GNUstep Events}). You
+can change these bindings in the usual way (@pxref{Key Bindings}).
+
+ The variable @code{ns-right-alternate-modifier} controls the
+behavior of the right @key{alt} and @key{option} keys. These keys
+behave like the left-hand keys if the value is @code{left} (the
+default). A value of @code{control}, @code{meta}, @code{alt},
+@code{super}, or @code{hyper} makes them behave like the corresponding
+modifier keys; a value of @code{none} tells Emacs to ignore them.
+
+ The standard Mac / GNUstep font and color panels are accessible via
+Lisp commands. To use the color panel, drag from it to an Emacs frame
+to change the foreground color of the face at that position (if the
+@key{shift} key is held down, it changes the background color
+instead). To discard the settings, create a new frame and close the
+altered one.
+
+ @key{S-Mouse-1} (i.e., clicking the left mouse button
+while holding down the @key{Shift} key) adjusts the region to the
+click position, just like @key{Mouse-3} (@code{mouse-save-then-kill});
+it does not pop up a menu for changing the default face, as
+@key{S-Mouse-1} normally does (@pxref{Temporary Face Changes}). This
+change makes Emacs behave more like other Mac / GNUstep applications.
+
+ When you open or save files using the menus, or using the
+@key{Cmd-o} and @key{Cmd-S} bindings, Emacs uses graphical file
+dialogs to read file names. However, if you use the regular Emacs key
+sequences, such as @key{C-x C-f}, Emacs uses the minibuffer to read
+file names.
+
+ On GNUstep, in an X-windows environment you need to use @key{Cmd-c}
+instead of one of the @key{C-w} or @key{M-w} commands to transfer text
+to the X primary selection; otherwise, Emacs will use the
+``clipboard'' selection. Likewise, @key{Cmd-y} (instead of @key{C-y})
+yanks from the X primary selection instead of the kill-ring or
+clipboard.
+
+
+@subsection Grabbing environment variables
+
+@c How is this any different to launching from a window manager menu
+@c in GNU/Linux? These are sometimes not login shells either.
+Many programs which may run under Emacs, like latex or man, depend on the
+settings of environment variables. If Emacs is launched from the shell, it
+will automatically inherit these environment variables and its subprocesses
+will inherit them from it. But if Emacs is launched from the Finder it
+is not a descendant of any shell, so its environment variables haven't been
+set, which often causes the subprocesses it launches to behave differently than
+they would when launched from the shell.
+
+For the PATH and MANPATH variables, a system-wide method
+of setting PATH is recommended on Mac OS X 10.5 and later, using the
+@file{/etc/paths} files and the @file{/etc/paths.d} directory.
+
+@node Mac / GNUstep Customization, Mac / GNUstep Events, Mac / GNUstep Basics, Mac OS / GNUstep
+@section Mac / GNUstep Customization
+
+Emacs can be customized in several ways in addition to the standard
+customization buffers and the Options menu.
+
+
+@subsection Font and Color Panels
+
+The Font Panel may be accessed with M-x ns-popup-font-panel. It
+will set the default font in the frame most recently used or clicked
+on.
+
+@c To make the setting permanent, use @samp{Save Options} in the
+@c Options menu, or run @code{menu-bar-options-save}.
+
+You can bring up a color panel with M-x ns-popup-color-panel. and
+drag the color you want over the emacs face you want to change. Normal
+dragging will alter the foreground color. Shift dragging will alter the
+background color.
+
+@c To make the changes permanent select the "Save Options"
+@c item in the "Options" menu, or run @code{menu-bar-options-save}.
+
+Useful in this context is the listing of all faces obtained by @key{M-x}
+@code{list-faces-display}.
+
+@subsection Open files by dragging to an Emacs window
+
+The default behaviour when a user drags files from another application
+into an Emacs frame is to insert the contents of all the dragged files
+into the current buffer. To remap the @code{ns-drag-file} event to
+open the dragged files in the current frame use the following line:
+
+@lisp
+(define-key global-map [ns-drag-file] 'ns-find-file)
+@end lisp
+
+
+@node Mac / GNUstep Events, GNUstep Support, Mac / GNUstep Customization, Mac OS / GNUstep
+@section Windowing System Events under Mac OS / GNUstep
+
+ Nextstep applications receive a number of special events which have
+no X equivalent. These are sent as specially defined ``keys'', which
+do not correspond to any sequence of keystrokes. Under Emacs, these
+``key'' events can be bound to functions just like ordinary
+keystrokes. Here is a list of these events.
+
+@table @key
+@item ns-open-file
+@vindex ns-pop-up-frames
+This event occurs when another Nextstep application requests that
+Emacs open a file. A typical reason for this would be a user
+double-clicking a file in the Finder application. By default, Emacs
+responds to this event by opening a new frame and visiting the file in
+that frame (@code{ns-find-file}). As an exception, if the selected
+buffer is the @samp{*scratch*} buffer, Emacs visits the file in the
+selected frame.
+
+You can change how Emacs responds to @key{ns-open-file} by changing
+the variable @code{ns-pop-up-frames}. Its default value,
+@code{'fresh}, is what we have just described. A value of @code{t}
+means to always visit the file in a new frame. A value of @code{nil}
+means to always visit the file in an existing frame.
+
+@item ns-open-temp-file
+This event occurs when another application requests that Emacs open a
+temporary file. By default, this is handled by just generating a
+@code{ns-open-file} event, the results of which are described above.
+
+@item ns-open-file-line
+Some applications, such as ProjectBuilder and gdb, request not only a
+particular file, but also a particular line or sequence of lines in
+the file. Emacs handles this by visiting that file and highlighting
+the requested line (@code{ns-open-file-select-line}).
+
+@item ns-drag-file
+This event occurs when a user drags files from another application
+into an Emacs frame. The default behavior is to insert the contents
+of all the dragged files into the current buffer
+(@code{ns-insert-files}). The list of dragged files is stored in the
+variable @code{ns-input-file}.
+
+@item ns-drag-color
+This event occurs when a user drags a color from the color well (or
+some other source) into an Emacs frame. The default behavior is to
+alter the foreground color of the area the color was dragged onto
+(@code{ns-set-foreground-at-mouse}). If this event is issued with a
+@key{Shift} modifier, Emacs changes the background color instead
+(@code{ns-set-background-at-mouse}). The name of the dragged color is
+stored in the variable @code{ns-input-color}.
+
+@item ns-change-font
+This event occurs when the user selects a font in a Nextstep font
+panel (which can be opened with @kbd{Cmd-t}). The default behavior is
+to adjust the font of the selected frame
+(@code{ns-respond-to-changefont}). The name and size of the selected
+font are stored in the variables @code{ns-input-font} and
+@code{ns-input-fontsize}, respectively.
+
+@item ns-power-off
+This event occurs when the user logs out and Emacs is still running, or when
+`Quit Emacs' is chosen from the application menu.
+The default behavior is to save all file-visiting buffers.
+@end table
+
+ Emacs also allows users to make use of Nextstep services, via a set
+of commands whose names begin with @samp{ns-service-} and end with the
+name of the service. Type @kbd{M-x ns-service-@key{TAB}@key{TAB}} to
+see a list of these commands. These functions either operate on
+marked text (replacing it with the result) or take a string argument
+and return the result as a string. You can also use the Lisp function
+@code{ns-perform-service} to pass arbitrary strings to arbitrary
+services and receive the results back. Note that you may need to
+restart Emacs to access newly-available services.
