Auto-Enclosing Blocks #142
Description
Is there such a thing in lua-mode already, i couldn't find it anyway and i think it is nice if the blocks get an end inserted automatically, so if i type function or while and hit enter or space-bar the end gets inserted. I added this to my init.el file which does it for me:
(defun put-block-end ()
"put ends of blocks"
(interactive)
(when (and
;; in lua mode
(derived-mode-p 'lua-mode)
;; enter or space
(member (char-before) '(10 32)))
(when
(save-excursion (backward-word)
(member (thing-at-point 'word)
'("do" "if" "for" "while" "function")))
(if (= (char-before) 10)
(progn ;enter
(insert "end")
(forward-line -1)
(forward-word)
(insert " "))
(progn ;space
(insert " " "end")
(backward-char 4))))))
And then:
(defun my-lua-mode-hook ()
(add-hook 'post-self-insert-hook 'put-block-end))
(add-hook 'lua-mode-hook 'my-lua-mode-hook)

Hi, please check https://github.com/Fuco1/smartparens and https://github.com/joaotavora/autopair, IIRC some of those provided that functionality. Up to the point when some people complained about it being too eager, eg #135 and #143.

If you'd like to have it implemented separately regardless, please keep the mentioned issues in mind to avoid inconveniences when editing comments or string literals (there's a
lua-comment-or-string-pfunction to help with this).
