default-directory launched from Dock macOS

default-directory launched from Dock macOS

[Tak Kunihiro]

I want to launch emacs from Dock on macOS.

From scratch buffer on emacs 26.3, C-x C-f prompts home directory
"~/".  However, from scratch buffer on emacs 27.0.91, C-x C-f prompts
root directory "/", which is inconvenient.  When I launch emacs
27.0.91 by `cd; emacs &`, C-x C-f prompts "~/".

Is there a good way to launch emacs 27.0.91 from Dock with
default-directory "~/"?

I noticed this too but I wasn’t sure if it was because MacOS changed
or emacs changed because I changed both roughly at the same time.

Aside from doing something in the init.el startup file, I’m curious what
the others suggest.

It's good to know I'm not the only one.

If you want this issue to be investigated and maybe fixed, please
submit a bug report with all the details.

Thanks.

When I set ‘initial-buffer-choice to anything other than default, for example my 
home directory “~/“, C-x C-f prompts that directory.

If I set it to “~/foo/bar”, C-x C-f will prompt ~/foo/bar.

Maybe try that?

Maybe it's related to how MacOS and Spotlight handle environment
variables when the app is launch by clicking its icon or using
spotlight.

There are good chance that your HOME environment variable is empty.

You can instruct MacOS about these environment variables by following a
post I wrote about it:

Hope this helps.

Thank you for the suggestion.  That does not change the response.
I will submit a bug report.

27.0.91; default-directory launched via Dock MacOS

[Tak Kunihiro]

I want to launch emacs via Dock or Spotlight on MacOS.

From scratch buffer on emacs 26.3, C-x C-f prompts home directory
"~/".  However, from scratch buffer on emacs 27.0.91, C-x C-f prompts
root directory "/", which is inconvenient.

When emacs 27.0.91 is started in home directory, C-x C-f prompts
"~/", as expected.

I think that C-x C-f should prompt home directory "~/" instead of root
directory "/" when emacs is launched via Dock or Spotlight.  Since
that worked good until emacs 26.3, something was changed on emacs 27.

Can you store the behavior back?  I show the recipe below to reproduce
the problem.

 $ cd; mv .emacs.d dot.emacs.d
 click emacs 27.0.91 on Dock
 C-x b *scratch*
 C-x C-f ; => Find file: /
 M-x kill-emacs

 $ ./Downloads/emacs-27.0.91/nextstep/Emacs.app/Contents/MacOS/Emacs &
 C-x b *scratch*
 C-x C-f ; => Find file: ~/
 M-x kill-emacs

 click emacs 26.3 on Dock
 C-x b *scratch*
 C-x C-f ;=> Find file: ~/

This sounded plausible but HOME is set to my HOME directory and USER is set to my user name.

It will be curious to learn what changed.

In your shell or in launchd?

Launchd is responsible for the environment variables your GUI apps
(launched by clicking their icon or using Spotlight) have access to.

> It will be curious to learn what changed.

If my theory is right, previous Emacs versions were doing some black
magic to find your home even if the HOME environment variable wasn't set
and new version doesn't try anymore and defaults to "/".

via launchd (open from the dock)

And that makes sense because launchd knows who owns the process.  e.g. the UID of Emacs is my user, not root.

    -+= 00001 root /sbin/launchd
     \-+= 00811 pedz /Applications/Emacs.app/Contents/MacOS/Emacs-x86_64-10_14
       \--= 15598 pedz /usr/local/bin/aspell -a -m -B --encoding=utf-8

It could be, but OS X has been doing weird things with that for a
while, and not just with paths.

That's an interesting solution, but there are a couple of others.

One option for use entirely within Emacs with elisp is this:

    https://github.com/purcell/exec-path-from-shell

I took a slightly different approach for launching Emacs from the Dock
that would inherit environmental variables and one or two other things
(including several, preconfigured Emacs server options), by making a
handful of these:

    https://github.com/adversary-org/emacs-launcher-osx

My solution is a bit more configurable since it's basically just
stripped down app container with just the Emacs icon and a shell
script to run a few things (like "source ~/.bashrc"), sometimes set
custom variables, and then launch Emacs.  Most of these are also set
to launch an Emacs server (with various applications configured to use
the relevant corresponding client).

Most of the time these[1] these all behave exactly as expected.

Ben
