Re: Can't insert curly brace for string interpolation in ruby-mode

[Steven Degutis]

(1) Yes, that's true. That's a limitation of emacs, not the open command. Do `emacs --help`

(2) Please do reply-all instead of just replying to me, so more people have an opportunity to answer you.

(3) None of this is related to curly braces in ruby-mode, i.e. the topic of this thread. Let's stay on topic.

When I try open -a emacs --args ${1+"$@"}, I have to choose either open a file, or provide a command line argument. I can't do both.

I'd like an emacs.sh script that I could pass command line arguments to. I wouldn't want to manually type "open -a emacs" each time.

This almost completely does the job:

open -a emacs $1 --args ${2+"$@"}

But it only supplies files for Emacs to load. It doesn't support command line arguments like -Q or -nw.

No, `open` works fine for this. Look again at the man page. It doesn't expect a binary like you were passing it (Contents/MacOS/Emacs). Instead you just pass it the name of an app bundle. The command I sent to you in the last email works perfectly.

Thank you.

I did use the man page, and I did try --args, but open complained. Could you suggest a better shell script?

First of all I highly recommend installing Cocoa Emacs from homebrew. Look here for how to install it properly: https://github.com/sdegutis/using-emacs#installing-emacs-properly

Secondly, you pass args to open via --args (look at `man open`). So it would be `open -a emacs --args -Q` if you want to launch Cocoa Emacs with -Q

Good idea!

Unfortunately I haven't been able to emacs -Q in Mac due to my poor setup. I can't even pass the option!

Could someone suggest a better way to do this?

$ which emacs

/usr/bin/emacs

$ cat `which emacs`

#!/bin/sh

open -a /Applications/Emacs.app/Contents/MacOS/Emacs "$@"

My goal is to be able to launch "emacs <dir/file>" from Terminal.app, such that Emacs doesn't steal control over the terminal while it runs. Ordinarly, one would use "emacs <dir/file> &", but I like to close the terminal, and I don't want Emacs to die with it. So I use "open -a..."

The problem with this arrangement is that this doesn't allow command line options to be sent to Emacs. "open" provides --args, but I haven't been able to use it properly.

This works fine for me in emacs 24.2.1.  And with 23.4.1 too.  What
version are you using?

Same here.

You didn't say so the obligatory response is, "Have you tried it with -Q?"

  emacs -Q

Works for me.
