[OS X Emacs] How to configure '~/.bash_profile' and '~/.bashrc' to work with Aquamacs?

[Christopher M. Balz]

Thank you Peter.  I made two changes that seem to do the trick (I had earlier done Aquamacs -> Tools -> Install Command Line Tools).  The changes were: a) Remove the '~/.emacs_bash' symlink I'd created; b) Create a '~/.bashrc' file containing an invocation of my alias-setting script; c) Invoke '~/.bashrc' from '~/.bash_profile' (leaving exported env vars in ~/'.bash_profile' where they belong).

Aquamacs seems to append '/usr/bin:/bin:/usr/sbin:/sbin:/usr/texbin' to the path it gets from '~/.bash_profile', but that doesn't seem to be a problem.  

 - cb

Otherwise, for example with a link from '~/.emacs_bash' to '~/.bash_profile', concatenated shell variables (commonly, $PATH) get a lot of redundant values in them.

Likewise, '.bashrc' executes once per *nix shell, including for Emacs shell buffers.

The difference of Mac OS X is that it launches processes *without* a shell's aid. So you need to wrap a shell (script) around the launching of Aquamacs Emacs. Or you launch it from a command line (open ...). Another way is to use ~/.MacOSX/environment.plist, documented in /Developer/Documentation/DocSets/com.apple.ADC_Reference_Library.CoreReference.docset/Contents/Resources/Documents/documentation/MacOSX/Conceptual/BPRuntimeConfig/Articles/EnvironmentVars.html or http://developer.apple.com/mac/library/documentation/MacOSX/Conceptual/BPRuntimeConfig/Articles/EnvironmentVars.html.


The file ~/.emacs_bash is executed when inside any Emacs a(n interactive) shell is started, by this shell instance. You can insert those statements that perform or set up something particular for Emacs.
