Changing $HOME

Changing $HOME

[Shug Boabby]

hi there,

i wish to change the definition of ~/ in the minibuffer. i have a folder
  /Users/shug/GNU
which i wish to use as my base... it makes life a lot easier for me 
since it allows me to seperate the OS X stuff from everything i do in 
Emacs and the CL.

i have tried doing things such as:
  (setenv "HOME" "/Users/shug/GNU")
or
  (setq homedir "/Users/shug/GNU")
but it never seems to work.

the best results i have are by
  (cd "/Users/shug/GNU")
but that just means i always start in that directory when looking for 
new files... it obviously doesn't redefine the ~/ symbol.

does anyone know how to define ~/ as "/Users/shug/GNU"?

Setting $HOME before starting emacs should work.  In bash:

$ HOME=/Users/shug/GNU emacs

sorry, i should mention... this is on the OS X Panther (CVS Carbon) 
builds... started from the Dock icon. i have absolutely no idea how to 
set envars from the OS X launcher. so thats why i am thinking about
  /Users/shug/.emacs

The environment given  to the graphical applications (is  different from the
shell    environment    and)   is    defined    in    the   property    list
~/.MacOSX/environment.plist

It is an xml  file that you can edit with the  «Property List Editor» app in
/Applications/Utilities folder.

Try «open  .MacOSX/environment.plist» to open  it easily : it  should launch
the editor.

HTH.

i do not have a ~/.MacOSX/environment.plist file and i have no idea
what to enter in
order to get Emacs alone to pick up on a few envars. the following
looks like it will
help though:
  http://developer.apple.com/qa/qa2001/qa1067.html

cheers!

Re: Changing $HOME

actually Sébastien, that sets the envars for ALL apps opened from the
dock.

i only want it to set HOME for Emacs.

thanks pascal... but the problem is that i only wish to set HOME for
emacs, but not the other dock (or OS X) apps.

Does this do the trick:

emacs -q --no-site-file
C-x C-f ~/.emacs RET
(setenv "HOME" "/where/you/want/to/be") RET
C-x C-s
C-x C-c
emacs

Re: Changing $HOME

[Shug Boabby]

i'm afraid not... that was the first thing i tried. try it yourself...
what happens if i try to open ~/file on the second loading is that it
tries to load the file
  /Users/shug/GNU/GNU/file
instead of
  /Users/shug/GNU/file

i think perhaps finding a way to get OS X to tell Emacs what HOME is on
starting is the best way to fix this problem. unfortunatley i cannot
find a way to do that... (unless i start emacs from the shell. but i'd
prefer to do it from the dock icon)

Then you can put:
     (putenv "HOME" "/some/path") 
at the start of your ~/.emacs

Of course, it'll use the normal $HOME to find ~/.emacs. If that's not
what you want, you only can write a trampoline script:

% cat ~/bin/emacs
#!/bin/bash
export HOME=/some/path
exec /usr/local/bin/emacs "$@"

Make it setenv

(I only use (setf (getenv "HOME") "/some/path") personnally...)

That's strange. If I read the code of `expand-file-name' correctly,
setenvinv HOME should be the right thing to do for what you want, as
it determines the expansion of "~" via a call to a C function:
egetenv ("HOME") -- which does the obvious.

Could you explain, in what way this does not work?  What directory do
you see, if you type `C-x d ~ RET'?

If not at the right one, please start Emacs like this:

emacs -q --no-site-file --eval '(setenv "HOME" "/User/shug/GNU")'

and post the value of the variable `process-environment' (which you
can get via `C-h v').

/Users/shug/GNU:
  wildcard GNU
  ls: GNU: No such file or directory

but i assure you that /Users/shug/GNU does indeed exist

(note i changed your "User" to "Users")

and i get the same results.

perhaps this is only broken in the OS X carbon builds?

i think i will try to solve this problem by getting OS X to pass the
correct environment onto Emacs when it starts. until then... a command
line wrapper is my friend.

Re: Changing $HOME

[Shug Boabby]

cheers pascal... but again, the problem is that i wish to do this in OS
X... from the dock start icon. you cannot put a script in the dock,
otherwise i would.

btw, putenv is void on my version.

my original plan was to have two .emacs files:
  /Users/shug/.emacs
    which would set HOME and load my *real*
  /Users/shug/GNU/.emacs
     which is my .emacs which i use on many platforms and i syncronise
quite a lot. so adding OS X specific stuff into this file is bad in my
book.

but an alternative would be to scrap the unnecessary .emacs and get OS
X to pass the HOME envar to emacs when started from the dock.
