Emacs, Mac OS X and opening from Shell

Emacs, Mac OS X and opening from Shell

[Alberto Simões]

Dear Emacs users,

I've been an Emacs user for some decades, but never a really emacs hacker.
In the latest months I've been using Sublime for Mac, but I am missing
emacs a lot.

So, in the come back, I am trying to make the emacs command to open an
emacs window, if one is open, or opening a new buffer in the current window
(and focus that buffer if possible).

Currently, my emacs command line is a shell script that looks like this:

   /Applications/Emacs.app/Contents/MacOS/Emacs "$@" &

This, of course, open a new window (although I usually close it, as the
buffers are shared among windows).

Any idea how I can make it behave as I described earlier?

Thank you,
Alberto

Make it invoke emacsclient instead.

It seems it opens another window as well :-(

Thanks

No, it doesn't, at least not by default.  Did you read its
documentation?

Well, as far as I understood, by default it should open in the same frame.
But it doesn't.
I tried adding the -c, that creates a new frame as promised (so, giving no
real difference).
I also tried -nw, but same behavior.

So, it seems to be a misbehavior of the MacOS Version (using this version -
http://emacsformacosx.com/)
Or I am really doing something wrong... that is *really* a possibility >:-)

Thanks,
Alberto

open(1) works for me, for example,

    $ open -a Emacs ~/.emacs.d/init.el

if *.el has been set Emacs as its default opening App, you can also omit '-a Emacs':

    $ open ~/.emacs.d/init.el

It should work out-of-box, i.e., no configuration needed from the Emacs
side, the following should works for you:

    # Start a fresh Emacs
    $ open -a /Applications/Emacs.app -n --args -Q
    # Open a file
    $ open -a /Applications/Emacs.app ~/.emacs.d/init.el


BTW, emacsclient(1) works as well. After 'M-x server-start' from a GUI
Emacs window:

    $ emacsclient --no-wait ~/.emacs.d/init.el

Hi all,

Sorry for posting at the top, but I think this is the correct place for
this:

as far as i can tell, the sh script I think is being executed, is not.
So, sorry, as I wasn't really testing emacsclient :-(

Best,
Alberto

I’m using this emacs for OS
X (https://github.com/railwaycat/homebrew-emacsmacport) and
"emacsclient -n" does what I expect.

By the way, make sure the emacsclient you call is not the one from the
system (in /usr/bin).
