AUCTeX Info Files in OS X

Question

I have Emacs installed from http://emacsformacosx.com/ and AUCTeX installed from homebrew. I used the option --with-emacs=/Applications/Emacs.app/Contents/MacOS/Emacs while installing AUCTeX. I am able to successfully load auctex.el and preview-latex.el using:

(add-to-list 'load-path "/usr/local/share/emacs/site-lisp")
(require 'tex-site)
(load "auctex.el" nil t t)
(load "preview-latex.el" nil t t)

However, AUCTeX's info files seem to be unavailable. I checked /usr/share/info/ and /Applications/Emacs.app/Contents/Resources/info/, the two default locations the info program searches for info files, but those related to AUCTeX are absent.

I looked at the AUCTeX tarball from the source and it does have the info files under doc/, which the INSTALL notes claim should be automatically installed during the installation process.

So what I am asking is:

1. Does homebrew install the info files for AUCTeX? If yes, where are they located?
2. If homebrew does not install the necessary info files, how can I copy them over from the source to the above mentioned directories. I guess I need to gzip them, so should I just include everything under the doc/ directory?

Answer 1

homebrew removes info files when installing packages. You can force homebrew to keep info files by setting $HOMEBREW_KEEP_INFO(as documented in man brew).

Set the environment variable $HOMEBREW_KEEP_INFO and re-install AUCTeX. Since you are already using homebrew, I'd suggest to also install Emacs from homebrew:

$ brew uninstall auctex
$ brew cleanup
$ export HOMEBREWW_KEEP_INFO=1
$ brew install emacs --cocoa --srgb
$ brew install auctex

You should now see AUCTeX info files in C-h i.

You may also want to consider installing AUCTeX via package.el (M-x package-install auctex).
