I need to devise an e-lisp macro, that would do the following: Assume I am now looking at a file named "/a/b/c/ZZZ/d/e.cpp", I'd like the macro to open "/a/b/c/YYY/d/e.h" for me. The elements a,b,c,d,e are unknown in advance, while elements ZZZ and YYY are a constant part of the path. How do I do this? (My understanding of e-lisp is pretty basic). I am using GNU Emacs 21.2.1.
