I want to configure my Emacs install to work with Gmail and I need to find my install location to configure it.
I installed Emacs on my Mac using Homebrew. Where would the install be located it? How can I find it?
Is there any other way to configure Emacs?
First, some references:
Official manual: https://www.gnu.org/software/emacs/manual/html_node/emacs/Init-File.html
Some discussion with examples: https://superuser.com/questions/73458/where-is-emacs-file
Brief answer: M-:user-init-file will print in the minibuffer the location of the configuration file which was used when this Emacs version started. Typically, this will be ~/.emacs, ~/.emacs.el or ~/.emacs.d/init.el.
There are several mail user agents (programs to manage emails) available in Emacs. Gnus is the one that comes with Emacs built-in. You can put Gnus-specific configuration in the Emacs init file, or you can put it separately in ~/.gnus file. I recommend reading this walk-through, if you will choose to use Gnus as your MUA: https://eschulte.github.io/emacs24-starter-kit/starter-kit-gnus.html . (This is the one I use too). A popular alternative is http://emacswiki.org/emacs/WanderLust but I wouldn't know how to set it up with GMail.
You do not need the install location to configure Emacs. You do so though a init file in your home directory.
The manual can tell you all you need to know about customizing emacs using the init file (or directory)
