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-option-modifier
|
|
|
|
On Mac, Emacs can use @key{control}, @key{command}, and @key{option}
|
|
|
|
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}, and @code{mac-option-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)
|
|
|
|
if its script is either Roman, Japanese, Traditional Chinese, Korean,
|
|
|
|
Cyrillic, Simplified Chinese, or Central European. Keyboard layouts
|
|
|
|
based on Unicode may not work properly. 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.,
|
2000-12-05 13:01:11 +00:00
|
|
|
@key{command}-@key{SPC} for switching input languages). These will not
|
2005-09-21 08:04:18 +00:00
|
|
|
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.

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.

The fontset @code{fontset-mac} is created automatically when Emacs
|
2005-09-21 08:04:18 +00:00
|
|
|
is run on Mac, and used by default. It displays as many kinds of
|
|
|
|
characters as possible using 12-point Monaco as a base font. If you
|
|
|
|
see some character as a hollow box with this fontset, then it's almost
|
|
|
|
impossible to display it only by customizing font settings (@pxref{Mac
|
|
|
|

You can use input methods provided either by LEIM (@pxref{Input

|
|

|
former, see the International Character Set Support section of the

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
|
2005-09-21 08:04:18 +00:00
|
|
|
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{Specify 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
|
2006-01-05 08:13:36 +00:00
|
|
|
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.
|
2005-09-21 08:04:18 +00:00
|
|
|
|
|
|
|
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.

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.
|
2005-09-21 08:04:18 +00:00
|
|
|
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.
|
2002-04-26 23:39:06 +00:00
|
|
|
|
2005-09-21 08:04:18 +00:00
|
|
|
Command line arguments are specified like
|
|
|
|
|
|
|
|
@example
|
|
|
|
/Applications/Emacs.app/Contents/MacOS/Emacs -geometry 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
|
2002-04-26 23:39:06 +00:00
|
|
|
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}.
|
2000-12-05 13:01:11 +00:00
|
|
|
|
|
|
|
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

|
Although Emacs on Mac does not support X resources (@pxref{X

|
|
|
|
resources. For example, adding the line
|
|
|
|
|
|
|
|
@example
|
|
|
|
Emacs.cursorType: bar
|
|
|
|

|
|
|
@noindent
|

|
|
|
|
|
|
|
@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
|

This node applies to Mac OS Classic only.
|

|
|
|
|
|
|
The directory structure in Mac OS Classic is seen by Emacs as
|
2000-12-05 13:01:11 +00:00
|
|
|
|
|
|
|
@example
|
2001-02-17 17:40:43 +00:00
|
|
|
/@var{volumename}/@var{filename}
|
2000-12-05 13:01:11 +00:00

|
|
@end example
|
|
|
|
|
2001-02-17 17:40:43 +00:00
|
|
|
So when Emacs requests a file name, doing file name completion on
|
2001-08-20 01:19:30 +00:00
|
|
|
@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
|
2002-04-26 23:39:06 +00:00
|
|
|
in the folder @file{Desktop Folder} in your boot volume (this folder
|
|

On Mac OS Classic, Emacs creates the Mac folder
|
2002-04-26 23:39:06 +00:00
|
|
|
@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.

It is rare that you need to specify a font name in Emacs; usually
|
2005-11-24 08:19:31 +00:00
|
|
|
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:
|

Native Apple fonts in Mac Roman encoding has maker name @code{apple}
|
2000-12-05 13:01:11 +00:00
|
|
|
and charset @code{mac-roman}. For example 12-point Monaco can be
|
2005-09-21 08:04:18 +00:00
|
|
|
specified by the name @samp{-apple-monaco-*-12-*-mac-roman}. When
|
|
|
|
using a particular size of scalable fonts, it must be specified in a
|
|
|
|
format containing 14 @samp{-}s like
|
|
|
|
@samp{-apple-monaco-medium-r-normal--13-*-*-*-*-*-mac-roman}.
|
|
|
|
|
|
|
|
You can specify a @code{mac-roman} font for @acronym{ASCII}
|
|
|
|
characters like
|
2000-12-05 13:01:11 +00:00

|
|
2005-09-21 08:04:18 +00:00

@lisp

'(font . "-apple-monaco-medium-r-normal--13-*-*-*-*-*-mac-roman"))
|
|
|
|
@end lisp
|
|
|
|
|
|
|
|
@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
|
|
|
|
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.
|
|
|
|
|
|
|
|
Since Emacs as of the current version uses QuickDraw Text routines
|
|
|
|
for drawing texts, only characters in the charsets listed above can be
|
|
|
|
displayed with the OS-bundled fonts, even if other applications that
|
|
|
|
use @acronym{ATSUI} or Cocoa can display variety of characters with
|
|
|
|
them.
|
|
|
|
|
|
|
|
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 fonts. The recommended way 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
|
|
|
|
Emacs uses the QuickDraw text rendering by default. On Mac OS X
|
|
|
|
10.2 and later, it can be changed so that it uses the Quartz 2D text
|
|
|
|
rendering (aka CG text rendering) by setting
|
|
|
|
@code{mac-allow-anti-aliasing} to @code{t}. However, it is reported
|
|
|
|
to sometimes leave some garbages.
