How to make emacs path aware on MacOSX

How to make emacs path aware on MacOSX

Apologies if this is the wrong forum for this. If so please redirect me.

I am running emacs on MacOSX, installed from a DMG file.

It works great, but it is not aware of my path, so I can't execute commands like 'git' or 'svn' etc.

How can I configure it to be aware of my path. I'm using the global path variable file /etc/profile.

/etc/profile only affects the Bourne shell or processes descended from
such a shell.

If you want global path changes to be visible to all programs, use
/etc/paths & /etc/paths.d/

The Finder on the Mac (that starts emacs) doesn't look at /etc/profile, etc.  For a particular user, it does look at ~/.MacOSX/environment.plist

Its a "property list" thing that is normal for Mac settings.  You can find it documented more on Mac forums and those kinds of places.

e.g. http://developer.apple.com/library/mac/#qa/qa1067/_index.html

If you are talking about shells started within emacs, thats a different matter.

It's *not* the Finder (it's Launch Service).

Another way to setup PATH is in your init file:

	(setenv "PATH" (concat "/some/directory" path-separator (getenv  
"PATH")))


Your shell can be corrected via ~/.emacs_<name of the shell  
interpreter>.

Thanks for the reply.

I must not have the environment syntax right.

I was able to set the path by adding in individual path elements like this:

/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/comcast/software/groovy/current/bin:/opt/comcast/software/grails/current/bin:/usr/local/git/bin:/usr/X11/bin:/opt/comcast/software/gradle/current/bin

But what I wanted to do was to set up some environment variables and include them in the path so as to shorten it:

SW_HOME /opt/summitbid/software
GROOV_HOME $SW_HOME/groovy/currrent

Path …:$GROOVY_HOME:/bin

But GROOVY_HOME never resolves to the actual path.

You have to "export" the variables in sh and bash. In csh or tcsh  
setenv does the same.

?

Sorry, but that doesn't make any sense to me. If I define a variable in
the environment.plist file, and then log out and back in (that's a pain)
the variables are available.

The problem is when I try to embed a variable in the value of another
variable: 

SW_HOME /opt/comcast/software
GROOVY_HOME $SW_HOME/groovy/current

In the case above, SW_HOME doesn't resolve correctly in the GROOVY_HOME
variable. 

It doesn't seem like exporting is the problem.

I did not understand completely what you wrote and assumed that you  
were still referring to the usual files a shell interpreter is reading  
when it is started.

Mac OS X allows to set up some so-called "Startup Items"...

That's indeed not possible inside ~/.MacOSX/environment.plist. It's  
just a simple text, or, better: XML file. Inside it no substitution  
happens. With GNU Emacs or some other editor it's really not that  
complicated to substitute variable names with the contents they stand  
for.

OTOH, a shell should be able resolve a setting like "$SW_HOME/groovy/ 
current" when "$SW_HOME" is given. Proof:

	ls -l $SW_HOME/groovy/current
