Tested out @ChillingHsu's method from above across a few different builds on macOS High Sierra 10.13 with Emacs 26, and found the following:

  • emacsclient works fine if you use emacs-plus.
  • emacsclient also works fine with Aquamacs (normal version installed via brew cask install emacs)
  • emacsclient doesn't work with emacs-mac, which doesn't install a /Applications/Emacs.app/Contents/MacOS/bin/emacsclient, and is therefore not available with or without the (server-start) parameter.

I like emacs-mac the most, since it works with my window manager. I currently run it by making EDITOR='open -a /Applications/Emacs.app, which opens the file in the existing window; sort of like having a persistent server.

How to place a hook for when one opens a file via the terminal?

(Using plain Emacs.app - no client/server)

Update: I can confirm either of these works:

(add-hook 'find-file-hook 'xxx)
(advice-add 'pop-to-buffer-same-window :after 'xxx)

Hello Vivek, I tried to change /Applications/Emacs.app/Contents/MacOS/bin/emacsclient to /usr/local/bin/emacsclient (emacs-mac). After that, this script would work well.

Hi, would anyone happen to know the current functioning approach for the brew cask install emacs-mac installation?

The default script installed by brew at /usr/local/bin/emacs (without args) doesn't open a background instance of emacs by default, as is my preferred behaviour. I know I could do $ alias emacs='emacs &', but I'm basically a novice in this whole game and:

  1. I don't know what negative consequences that might have, and,
  2. I'm keen to get my hands on a working current solution as a case-study, and see why the other methods weren't working (or where I'm going wrong) for the sake of education in the ways of the shell.

Maybe someone knows whether me using the Spacemacs distribution or the Zsh shell would break these approaches?
(RE Spacemacs, when I attempted to use @ChillingHsu's approach I tried placing the (server-start) line in init.el, as well as every possible section of my .spacemacs file without luck)

Thanks very much

Hi SolidStill, as a fellow spacemacs user I also faced some issues getting this setup.

I've written a short blog post about my emacs/spacemacs installation and setup which hopefully might help you. I used a combination of the code snippets from here but had to change a few things. You will also need to disable all of the spacemacs server variables in your .spacemacs file. I detail this in the post though.

Best of luck.

Just scanned thorugh your blog post @aidanscannell; thanks v much for taking the time to reply - your post touches on a few key additional topics I've been trying to develop a decent understanding of: Latex authoring in emacs on macos, version-controlling emacs setups/configurations.

Funnily enough, I actually graduated from Bristol with a Maths BSci in 2010, never used that education in any meaningful way, and am now training myself up to get a job in data analysis. I'm looking to redevelop a technical mindset/mentality by getting into the guts of (and really understanding) all the tools/methods/theory I encounter along that journey. Your post really nails the kind of efficiently-verbose and well-reasoned exposition that is crucial in really developing understanding in a concept, as opposed to just becoming familiar with a concept.

In all honesty, the temptation to pester you with emacs-related technical support questions is probably going to be too strong to resist. I'm truly glad that I eventually noticed this post, "being less amateur with Github notifications" is def going on my learning-list. Thanks for the inspiration and kudos for helping deliver Skynet to mankind 😛

Hi @mwolson, thanks for the update. I believe your starter script works for Nextstep port (although I haven't verify that by myself), but it not works for Mac port. Because Emacs Mac port lacks multi-tty support, which means, emacsclient from mac port can only able to create tty frames but not GUI frames.

@railwaycat This seems outdated. I'm able to open GUI emacs from emacsclient now. Could you update instructions for this? However, the Emacs server in GUI app won't run in the background. C-x C-x the last window closes the app and also the server. This behavior is different from the official Emacs build. Their Emacs.app can run without any window.
