More fun with EProject

I am really enjoying using Jonathan Rockway's Eproject for Emacs. It's project management done in a minimalistic way that lends itself to many useful elisp hacks. As well as the scons/flymake project definition that I use, there's also a nifty hack that allows header/source file definition switching that I just cooked up.

	;; a convienence function that lets us switch between source/header files in a project
	(defun buffer-other-eproject-files ()
	(interactive)
	(let*
	((buffer-file (file-name-nondirectory (buffer-file-name)))
	(other-buffer-files
	(delq nil
	(mapcar (lambda (x) (and
	(equal (file-name-nondirectory (file-name-sans-extension x)) (file-name-sans-extension buffer-file))
	(not (equal (file-name-nondirectory x) buffer-file))
	x)) (eproject-list-project-files)))))
	(when (> (length other-buffer-files) 0)
	;; TO DO : Possibly prompt if there is more than one..
	(find-file (car other-buffer-files)))))

It's only a few lines long but already useful. It's simple because eproject will simply list all the files in the current project for you, then you can pick out the duplicate...
