(defun my-set-truncate-lines ()
   "Set `truncate-lines' to t when visiting a file whose extension is
\"ext1\", \"ext2\", or \"ext3\"."
   (when (member (file-name-extension buffer-file-name)
		'("ext1" "ext2" "ext3"))
     (setq truncate-lines t))
   ;; return value for find-file-not-found-hooks:
   nil)

(add-hook 'find-file-hook 'my-set-truncate-lines)
