I used Emacs for over 10 years, but stopped using it when I had to administer nearly 100 servers, where I was not allowed to install Emacs. With the birth of the St. Louis Emacs User Group, I've decided to try to start using Emacs again.

I've decided to start with Prelude, since it provides a lot of add-on packages with decent configuration out of the box.


# Make sure we have the latests Homebrew.
brew update
# Install ctags, which Emacs likes to use to index source files to find function definitions.
brew install ctags
# Install latest version (24.3) of Emacs. Include Mac OS X GUI support with sRGB colors.
brew install --cocoa --srgb emacs
# Link into /Applications folder.
brew linkapps
# Link executables into the PATH, before system versions.
EMACS_VERSION=$(ls -1 /usr/local/Cellar/emacs | tail -1)
ln -sf /usr/local/Cellar/emacs/$EMACS_VERSION/bin/{emacs,emacsclient} /usr/local/bin/
hash -r
# Install Prelude.
mkdir -p ~/.emacs.d
git clone git:// ~/.emacs.d/prelude


# Create a .emacs file that will load Prelude, but allow for personal customization.
cat > ~/.emacs.d/init.el <<-EOF

  • Store my .emacs.d/init.el file in my config_files repo.
  • Break up init.el file into pieces:
    • packages.el
    • keymap.el
    • theme.el
    • ruby.el
    • prelude.el (maybe)
  • Need to make sure rubocop command is installed in all Ruby versions.
    • It's used by the Prelude Ruby mode.
