I'm not retyping any paths either, that's the whole point (lisp-dir (format "%s/lisp" emacs-dir)) (init-dir (format "%s/emacs-init" emacs-dir)) (erc-dir (format "%s/erc" init-dir)) (gnus-dir (format "%s/gnus" init-dir)) (ide-dir (format "%s/ide" init-dir)) (w3m-dir (format "%s/w3m" init-dir)) I retype variable names of the variables that hold them but that's another thing, if I make a typo there Emacs should warn me somewhere along the way. And more than that, it is just a principle which is sound to always uphold not duplicate the same data. -- underground experts united https://dataswamp.org/~incal
