Sometimes you want every source file to have a common header. Perhaps a copyright notice, perhaps specifying emacs local variables.
The following emacs command does just this that. It uses a end-of-header sentinel. If it's exists, the header is updated. If not, it is added at the beginning of the file
insert-header-core is the main program, and
insert-header is your locally customized version. For whatever reason, make sure your
headertag ends with a newline
(defun insert-header-core (headertag headerfile) "insert a source file header" (interactive) (goto-char (point-min)) (kill-region (point-min) (progn (search-forward headertag nil t 1) (point))) (insert-file headerfile) ) (defun insert-header () (interactive) (insert-header-core "/* HEADER END */\n" "header.txt") )
