Been an emacs user for 5 years and have tried all the mac ports. This is BY FAR the best I've used, both under the hood and and in appearance. It even has smooth pixel scrolling, pinch zoom, and some nifty mac specific optimizations.
You can quit (while t) and (shell-command "sleep 100").
No bogus menu bar activation while these evaluations.
Emulation of `select' without periodic polling
It doesn't use CPU time while the Lisp interpreter is idle and
waiting for some events to come, even with subprocesses or
If you try logout/shutdown/reboot while leaving a file-visiting
buffer modified and unsaved, a popup window appears for
confirmation. If you cancel the termination of Emacs (including
C-g or ESC), the whole logout/shutdown/reboot process is also
canceled immediately (i.e., you will see a "canceled" dialog
immediately rather than a "timed out" one afterward). If you
don't have unsaved buffers, shell buffers, etc., you won't see
Apple event handling
One can define Apple event handlers at the Lisp level.
Actually, graceful termination above is an instance of
Lisp-level Apple event handling. Another example is "Get URL"
handler that enables us to invoke the mailer you customized with
$ osascript -e 'tell application "Emacs"
to open location "mailto:firstname.lastname@example.org"'
If you set Emacs as the default mailer via Mail.app preference,
the Emacs mailer will set up a draft buffer when you click a
mailto: link in a Web browser.
You can look up a word under the mouse pointer in the selected
window by typing Command-Control-D (or double/single-tapping a
trackpad with three fingers on Mac OS X 10.7/10.8, resp.).
Resolution independence (10.4 - 10.6, 10.5 recommended)
Scaling works in Framework-Scaled Mode as opposed to (blurry)
Magnified Mode for the Carbon port.
Note: this type of resolution independence is deprecated on Mac
OS X 10.7.
64-bit (10.5 and later)
You can build and run a 64-bit binary with GUI support by
specifying CC="gcc -arch x86_64" or CC="gcc -arch ppc64" on
Some minor visual enhancements
- Aligned key bindings in menus
- Progress indicator (corresponding to hourglass) in the title bar
- Unusable items in the font panel are hidden
Try Options -> Show/Hide -> Font Panel from the menu bar or
M-x mac-font-panel-mode RET.
- Update display while the resize control (or the slider in the
font panel) is being dragged
fullscreen' frame parameter, with all values supported:
fullboth frames, which don't have the title bar, still allow us to
access the menu bar, the Dock, and the tool bars. The menu bar
can also be activated viamenu-bar-open',
Control-F2' (if full
keyboard access enabled), orCommand-Shift-/' (on Mac OS X 10.5
and later) even for fullboth frames where the menu bar is usually
hidden. Changing fonts or internal-border-width in fullscreen
frames does not clutter display. On multiple monitor
environments, one can move fullscreen frames to another monitor by
left' andtop' frame parameters accordingly.
Attaching/detaching external monitors should work even with
- The `sticky' frame parameter, which allows us to keep particular
frames visible for all Spaces on Mac OS X 10.5 and later.
- The function
system-move-file-to-trash', which can be specified
as a value ofdelete-by-moving-to-trash'.
- SVG image display. This can be done via the WebKit framework, so
you don't need librsvg.
- Multi-page TIFF images.
- The function
x-select-font' that provides modal font selection
dialog in a compatible way with GTK+ and W32 ones. Note that a
nonmodal counterpart has been available since Emacs 22 Carbon port
- Unicode character display including non-BMP ones.
- Complex Text Layout and text shaping. They are implemented using
the Core Text or NS Text layout engine, so you don't need libotf.
Glyph selection with variation selectors. Most of Adobe-Japan1
ideographic glyphs are accessible via IVSes (Ideographic Variation
Sequences) even for the OS-bundled Hiragino fonts, which do not
contain the UVS subtable in their cmap table as of Mac OS X 10.6.
Can be compiled with the ImageMagick support. Even without the
ImageMagick library, the Mac port provides a fallback using the
Image I/O framework so you can scale and rotate images.
- The variable
tool-bar-style' works like in GTK+. The values
text-image-horiz' are synonymous withboth'.
- Pixel-based mouse wheel smooth scroll for newer mice/trackpads.
- Gesture event handling for newer trackpads. By default, pinch
out/in are bound to text size scaling. With the shift key, they
turn on/off fullscreen status of the frame.
- Apple event sending with (a)synchronous reply handling. ODB
Editor Suite support is added as an example. (Only tested with
QuickCursor. Add "org.gnu.Emacs" to the elements
of QCEditInChoices in QuickCursor.app/Contents/Info.plist. On
QuickCursor 2.0, you need to kill the buffer after saving it in
order to reflect the changes to the original text area.)
- "Click in the scroll bar to: Jump to the spot that's clicked"
setting in the System Preferences is supported. Pressing the
option key while clicking toggles this behavior temporarily.
- Change of text smoothing threshold setting in the Appearance pane
of the System Preferences is reflected immediately.
- Several keyboard shortcuts (notably those for Keyboard Navigation)
listed in System Preferences just work like other applications.
- When the clipboard has both textual and image data, yank inserts
the former and push both into the kill ring so the latter can be
inserted with yank-pop afterwards.
- Use non-integral x positions for displaying antialiased
proportional fonts. You can see the difference by putting the box
cursor over Helvetica 12pt `I', whose ideal width is 3.33398 but
displayed with the rounded width 3, for example.
- Emacs info nodes are accessible via search field in the Help menu
on Mac OS X 10.6 and later.
- Menu item "Open Selected File in Emacs" is shown in Services or
context menu of other applications by default on Mac OS X 10.6
and later when absolute pathname-like text is selected.
- Reverse conversion in Kotoeri works even without selection.
Hitting Eisu/Kana key on JIS keyboard (or Control-Shift-;/J/K on
US keyboard) twice also works.
- New function
mac-file-alias-p', which is parallel to
- Experimental support for accessibility with respect to the custom
view for Emacs frames. It is required to support "Text to Speech"
on Mac OS X 10.7. Still there are several glitches.
- Can display color bitmap fonts such as Apple Color Emoji, if
compiled and executed on Mac OS X 10.7 or later. Also supports
display of some combinations of regional indicator symbols, such
as U+1F1EF followed by U+1F1F5, as national flags. Variation
Selectors 15 (text-style) and 16 (emoji-style) are also supported.
- New function `mac-start-animation', which provides animation
effects on Mac OS 10.5 and later via Core Animation. You can see
the default animations with buffer switching by horizontal
swiping/flicking, exiting from the splash screen by typing "q",
and the "About Emacs" and "Preferences..." menu items in the
application menu (labeled "Emacs") in the menu bar.
