I tried to add your script into my .emacs file, but it seems I made a
mistake somewhere. This is what emacs reports in backtrace:
Debugger entered--Lisp error: (void-variable c++-mode-map)
(define-key c++-mode-map (kbd "C-S-h") (quote my-goto-h-file))
eval-buffer(#<buffer *load*> nil "~/.emacs" nil t)
load-with-code-conversion("/home/daniel/.emacs" "~/.emacs" t t)
load("~/.emacs" t t)
[...]
What did I do wrong?
P.S. I want to be able to go back and forth: .cpp -> .h -> .cpp. Would
this do it?
(defun my-goto-h-file ()
(interactive)
(when (string-match "\\.cpp$" (buffer-file-name))
(let* ((h-file (format "%s.h"
(file-name-sans-extension (buffer-file-name)))))
(when (file-exists-p h-file)
(find-file h-file))))
(when (string-match "\\.h$" (buffer-file-name))
(let* ((h-file (format "%s.cpp"
(file-name-sans-extension (buffer-file-name)))))
(when (file-exists-p h-file)
(find-file h-file)))))
