upgrading console emacs (/usr/bin/emacs) on Mac

Question

I extensively use /usr/bin/emacs in Terminal.

I have Emacs 22 and I'd like to upgrade it to 23. I wonder how to do it.
Googling "emacs download mac" gives me Emacs.app which has its own window and user interface, but I don't want that.

I am not sure how I have /usr/bin/emacs in the first place, maybe it came with Mac OS?

Answer 1

You can run the Emacs.app version in a terminal like this:

/Applications/Emacs.app/Contents/MacOS/Emacs -nw 

In my .cshrc file, I use an alias to make this easier to invoke:

alias enw '/Applications/Emacs.app/Contents/MacOS/Emacs -nw' 

Answer 2

It is a standard editor included with OS X and a lot of other *nix systems along with vi/vim, and pico. Personally i wouldnt upgrade the pre-installed one. I would install from Macports, Fink, or Homebrew or compile from source myself to a different location (like /usr/local).

Answer 3

Install emacs from macports.

% sudo port install emacs

Then launch it from the terminal
