Emacs Mac Port

Hey guys,

If you are on a Mac, you *should* start using this:

https://github.com/railwaycat/emacs-mac-port

I've been having some serious issues with the vanilla Cocoa Emacs lately on
Mavericks, including a nasty memory leak that would somehow trigger
distnoted and put the CPU usage at 100% every hour or so.

Besides being quite stable, it has some nice usability improvements made
specifically to make Emacs integrate better with OSX. My orgmode experience
has been much better since I started using it!

Thought I'd share :)

Cheers,

Marcelo.

I second this. Things I really like are:
- fast flyspell (I was having issues because of syntax highlighting in
vanilla emacs);
- several full screen modes (native OS X fullscreen, or just "take the
whole screen with no menu bar" version, which I prefer);
- smooth scrolling;
- double tap with three fingers to get dictionary entries (OK, I admit
it's a gimmick, but it's fun nonetheless).

I'm curious about this one -- any screencast demonstrating
this?  Any hint on what part of the Emacs display engine has
been improved to get this?

Thanks,

I don't know how to make a screencast ... but what I refer to is this in
the feature list
(https://github.com/railwaycat/emacs-mac-port/blob/master/README-mac):

  * Pixel-based mouse wheel smooth scroll for newer mice/trackpads.

Searching for a bit, I think it's related to this code:

Somewhat off-topic, but just use Quicktime Player:
File > New Screen Recording.

I like to recode the resulting file afterwards using Handbrake,
reducing resolution (and stripping the sound track or even color where
possible) allows quite tiny files with a good frame rate.

Cheers, Bernd

Interesting, because with the Emacs (from emacsforosx.com), I have
been hitting 100% cpu problem again and again lately. I had tried out
this port, but I hit 2 issues and put it aside:

- with the same theme (solarized-dark), the background with the
railwaycat port is darker!  minor issue, of course. 
- gnus (when trying to access nntps servers with gnutls) gets
stuck. I'll need to debug that, unless someone has a trick up their
sleeve.

I may just give it a try for my regular work, I run gnus in a
different Emacs, so that can continue to run on the other port.

Wow! Thanks, Marcelo. If this is indeed the cause of the performance
problems I've been seeing, this will save me many agonizing hours. I
never suspected emacs in these problems, but I've certainly seen
distnoted turn into a complete CPU hog. I have emacs running all the
time, so if that's the cause, this will be a huge relief.

Thanks!

+1

I swear by this port.

A few other cool things it has:

High resolution versions of tool bar icons and the splash screen image for Retina.

- DictionaryService support
      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.).

* 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.

+ tons more

The port is developed by YAMAMOTO Mitsuharu and his last announcement is at:
