Well, set it manually (not tested). Emacs can not possibly know about
all statement delimiters of all languages out there:
;;; Add more either here or using
;;; (setq dh-eos-alist (cons '(mode . "str") dh-eos-alist)
(defvar dh-eos-alist '((c-mode . ";")
(c++-mode . ";")
(java-mode . ";")))
(defun dh-insert-eos ()
(interactive)
(let ((eos (assq major-mode dh-eos-alist)))
(insert (if eos
(cdr eos)
""))
;; Change this if you don't want auto-indent.
(newline-and-indent)))
;; May be problematic outside of X. Use the output of C-h k as an
;; argument to `kbd' for "weird" keys.
(global-set-key (kbd "<S-return>") #'dh-insert-eos)
