A good tags file is essential when developing with emacs. My tags setup (see Adam’s dot files) didn’t work out of the box on my Mac. It turns out that the included ctags is ancient. The simple fix is to install a newer version of ctags with Darwin Ports.
sudo port install ctags
Adam Doppelt, a former coworker and emacs enthusiast, has shared his emacs dotfiles with the world.
This collection of lisp files has a rich set of features that I have found indespensable as a developer: source code highlighting, tags, source control integration, etc. I look forward to see what new tricks Adam has added.
